NOTE The Determination of Prices

1
00:00:00.000 --> 00:00:06.000
To sum up quickly what we've done so far, we have the law of diminishing marginal utility,

2
00:00:06.000 --> 00:00:13.000
the fact that you increase the more, the greater your supply, do you have any product, lower

3
00:00:13.000 --> 00:00:19.000
the value of each unit, and that we solve the value paradox, why there seems to be a

4
00:00:19.000 --> 00:00:24.000
difference between use value and exchange value, there really isn't, and we've got

5
00:00:24.000 --> 00:00:29.000
the concept of the elasticity, we've got the falling demand curve, like so, we've got the

6
00:00:29.000 --> 00:00:34.680
The concept of elasticity of the demand curve and what it means, so that if the demand curve

7
00:00:34.680 --> 00:00:42.680
is very inelastic, it means that total revenue will decline as the price goes down and go

8
00:00:42.680 --> 00:00:44.000
up as the price goes up.

9
00:00:44.000 --> 00:00:50.640
If you have a flattish or more elastic demand curve, that means as the price goes down,

10
00:00:50.640 --> 00:00:56.560
total revenue goes up, and vice versa, total revenue will fall when the price goes up.

11
00:00:56.560 --> 00:01:03.160
So, that's the basic concept. What happens to total revenue when price changes?

12
00:01:03.160 --> 00:01:10.160
Okay, we now, that's the summing up we've done so far. We now go from that to the key

13
00:01:10.160 --> 00:01:15.840
point of microeconomics. I mean, how are prices determined? Why is the price what it is? Why

14
00:01:15.840 --> 00:01:20.160
is the price of oil whatever it is? Why is the price of Wonder Bread whatever it is?

15
00:01:20.160 --> 00:01:24.640
Why is the wage rate, as we'll see later on, what it is? All prices on the market, and

16
00:01:24.640 --> 00:01:30.620
There are millions of exchanges and each exchange has different terms of exchange. Each exchange

17
00:01:30.620 --> 00:01:39.620
has a price. There's money, two cents a nail, 50 cents for a Dove bar, $180 for a TV set,

18
00:01:39.620 --> 00:01:45.140
whatever happens to the data, these are prices. And so now we've got to the question of what

19
00:01:45.140 --> 00:01:50.320
determines prices. In contrast, people don't know any economics. It's not chaotic. It's

20
00:01:50.320 --> 00:02:20.320
It's not purely, it's not arbitrary, it's not chaotic, there are definite reasons, factors that determine prices, and it's basic, basically you've got two things, you've got, here's price on the y-axis, so any particular good or service, quantity on the x-axis, you have your falling demand curve, which we've already talked about, which all we know about is it's falling, it might be inelastic, it might be elastic.

21
00:02:20.320 --> 00:02:26.200
And then we have supply of the good. In other words, how much is there? Forget about the

22
00:02:26.200 --> 00:02:30.280
textbook of the rising supply curve. The supply is vertical. In other words, at any given

23
00:02:30.280 --> 00:02:35.560
time, at any given moment, at any given freeze frame, we've got a certain amount of stuff

24
00:02:35.560 --> 00:02:42.040
there. Why it's there, we'll get into later. Let's say there's 100,000 loaves of wonder

25
00:02:42.040 --> 00:02:45.320
bread right now in New York. I don't know how many there are, but let's say 100,000

26
00:02:45.320 --> 00:02:52.320
We need to be sold. In that case, we don't know how many there will be next week or next year. We'll talk about that later.

27
00:02:52.320 --> 00:02:58.320
But right now, at this moment, we need to be sold. There's a supply of 100,000 loads.

28
00:02:58.320 --> 00:03:02.320
So this is a vertical supply line. In this case, 100,000.

29
00:03:02.320 --> 00:03:09.320
Of course, this quantity is going. It increases as you go to the right. This is zero.

30
00:03:09.320 --> 00:03:12.320
And it keeps increasing as you go this way.

31
00:03:12.320 --> 00:03:18.680
So now we have a vertical supply line, we've got a demand curve which is falling, and we

32
00:03:18.680 --> 00:03:21.600
have an intersection point.

33
00:03:21.600 --> 00:03:25.200
And what I'm going to prove now, I'm going to make this statement, I haven't proved it,

34
00:03:25.200 --> 00:03:27.200
I'm just going to make a flat statement.

35
00:03:27.200 --> 00:03:31.440
What I'm going to prove now is the single most important thing in the course, namely

36
00:03:31.440 --> 00:03:37.000
that the price of anything, the price of any good or service at any day, at any time will

37
00:03:37.000 --> 00:03:43.000
will tend to be the intersection point of the demand curve and the supply line.

38
00:03:43.000 --> 00:03:47.000
If it isn't at that point, it will tend rapidly toward it.

39
00:03:47.000 --> 00:03:50.000
So this is what I'm going to demonstrate.

40
00:03:50.000 --> 00:03:58.000
Alright, supposing this is anything. It's wonder bread, it's fish, it's high-fi sets, it's nails, it doesn't make any difference.

41
00:03:58.000 --> 00:04:05.000
Let's say at any given day, we start the day with this point.

42
00:04:05.000 --> 00:04:23.000
Let's say the price is, let's say it's $1.50 a loaf, it starts at $1.50 a loaf, I'll add $1.50 a loaf, this much will be bought, that's where we already determined that.

43
00:04:23.000 --> 00:04:30.000
The bank card tells you, excuse me, how much the consumers will purchase or the buyers will purchase at any given price.

44
00:04:30.000 --> 00:04:34.000
At this point, let's say they purchase $70,000.

45
00:04:34.000 --> 00:04:39.000
Well, they've produced $100,000. $100,000 low is ready to be sold.

46
00:04:39.000 --> 00:04:41.000
They're only selling $70,000.

47
00:04:41.000 --> 00:04:46.000
In other words, what you've got is a gap between the supply ready to be sold

48
00:04:46.000 --> 00:04:49.000
and the amount purchased, the demand.

49
00:04:49.000 --> 00:04:53.000
This is unsold surplus.

50
00:04:53.000 --> 00:04:59.000
In other words, at this price, the supply is greater than demand.

51
00:04:59.000 --> 00:05:04.000
The amount of goods available to be sold is greater than the amount purchased.

52
00:05:04.000 --> 00:05:07.000
There's anything businessmen don't like.

53
00:05:07.000 --> 00:05:11.000
Businessmen are motivated here by one, two very simple motivations, actually one,

54
00:05:11.000 --> 00:05:14.000
to make as much money as they can and to avoid losing any money.

55
00:05:14.000 --> 00:05:19.000
In other words, to maximize their profits and avoid losses or minimize losses.

56
00:05:19.000 --> 00:05:21.000
They're losing money by not selling this thing.

57
00:05:21.000 --> 00:05:24.000
They've bought the bread, the retail stores have bought the bread.

58
00:05:24.000 --> 00:05:26.000
They ain't selling it.

59
00:05:26.000 --> 00:05:30.000
How do you sell an unsold surplus?

60
00:05:30.000 --> 00:05:32.000
Well, they try it. They lower the price a little bit.

61
00:05:32.000 --> 00:05:36.000
And by God, if they lower the price, they find they're selling more Wonder Bread.

62
00:05:36.000 --> 00:05:40.000
Or whatever else it is. Gear Shifts or Apples or whatever.

63
00:05:40.000 --> 00:05:44.000
As they keep selling it then, they find out the unsold surplus is gone.

64
00:05:44.000 --> 00:05:50.000
And so, they keep lowering the price until they get to this point here, the intersection point.

65
00:05:50.000 --> 00:05:54.000
And as they do that, they sell the unsold surplus.

66
00:05:54.000 --> 00:06:02.040
The only point at which the quantity supplied, if you're supplying 100,000, this is exactly

67
00:06:02.040 --> 00:06:04.640
how much consumers are willing to buy, 100,000.

68
00:06:04.640 --> 00:06:11.080
In other words, you eliminate the unsold surplus, a terrible headache for any businessman, by

69
00:06:11.080 --> 00:06:14.640
lowering the price until you get to this point.

70
00:06:14.640 --> 00:06:19.840
You have a built-in mechanism, so to speak, in the market, free market, a built-in mechanism

71
00:06:19.840 --> 00:06:25.140
and driving the price down to the intersection point because the higher the prices, the greater

72
00:06:25.140 --> 00:06:26.140
the unsold surplus.

73
00:06:26.140 --> 00:06:29.840
And as I say, as you keep lowering the price, you find out by trial and error, you find

74
00:06:29.840 --> 00:06:37.360
out very quickly as you lower the price, you sell more to find the unsold surplus is eliminated.

75
00:06:37.360 --> 00:06:41.200
On the other hand, supposing you start off the day with prices below the equilibrium

76
00:06:41.200 --> 00:06:48.200
price, let's say this is a dollar, say you start at 75 cents, okay, supposed to be a

77
00:06:48.200 --> 00:07:18.200
at 75 cents, surely you can sell a whole 100,000. There's something else happening here. People are willing to buy now because you have a falling demand curve. They're willing to buy 120,000 lobes. They're trying to buy 120,000 lobes. They can only find 100,000. In other words, you have a situation of demand being greater than supply, which is also called excess demand. You have people trying to find the stuff and it ain't there. In other words, you have a phenomenon of empty shelves.

78
00:07:18.200 --> 00:07:22.200
Where's my Wonder Bread? Gee, we sold out at 11 o'clock this morning.

79
00:07:22.200 --> 00:07:26.200
So, what happens then is the so-called shortage.

80
00:07:30.200 --> 00:07:34.200
So what you have then is a shortage. In other words, all of a sudden, my god, we've sold out.

81
00:07:34.200 --> 00:07:38.200
The businessmen realize, my god, if we can sell out at a cheap price, let's raise the price.

82
00:07:38.200 --> 00:07:41.200
Why are we losing money on this thing? We're forgoing a lot of money.

83
00:07:41.200 --> 00:07:46.200
And they find out that as they raise the price, the shortage is getting progressively eliminated.

84
00:07:46.200 --> 00:07:53.200
So what you have then in the market, every place in the market, the entire market economy, the reason why it works, I mentioned it I think before last week, it always works, it always works meaning there's never any shortage and there's never any surplus, in other words, there's never any surplus.

85
00:08:16.200 --> 00:08:20.520
Unsold surplus running like the time, disappears very quickly, never any shortage because it

86
00:08:20.520 --> 00:08:27.000
disappears quickly. The reason is the prices are flexible and the motivation to arrive

87
00:08:27.000 --> 00:08:35.000
at this intersection point is trying to increase your profits and trying to avoid losses. And

88
00:08:35.000 --> 00:08:39.520
by doing that, the free market economy is such, it always wipes out and very quickly

89
00:08:39.520 --> 00:08:43.700
wipes out all shortages and all surpluses, that you always wind up at this equilibrium

90
00:08:43.700 --> 00:08:51.700
equilibrium point. It's called an equilibrium point. The intersection point, the intersection price is called equilibrium price.

91
00:08:51.700 --> 00:09:06.700
The reason it's called equilibrium, once again an analogy with physics, physical sciences, something is in equilibrium when it tends to stay there and if this place from that point will return to it quickly.

92
00:09:06.700 --> 00:09:10.900
okay so that's exactly what happens here in this case is a pretty good analogy

93
00:09:10.900 --> 00:09:15.060
I'm not a fan of physical analogies in economics but in this case is pretty good

94
00:09:15.060 --> 00:09:18.960
one namely that it tends to remain there and if it's displaced from it it goes

95
00:09:18.960 --> 00:09:27.140
back and goes back very quickly day-to-day basis so driven by profit

96
00:09:27.140 --> 00:09:31.380
motive and with a flexible free price if the price is free to change there's no

97
00:09:31.380 --> 00:09:35.820
legal reason not to change there's no law against it we'll get to that pretty

98
00:09:35.820 --> 00:09:42.380
Soon, then the market economy is such that the prices always reflect, always equate supply

99
00:09:42.380 --> 00:09:43.380
and demand.

100
00:09:43.380 --> 00:09:49.340
In other words, they make supply and demand equal, this is also called clearing the market.

101
00:09:49.340 --> 00:09:57.140
In other words, it clears the market of any excess supply or unsold surplus and of any

102
00:09:57.140 --> 00:10:01.660
excess demand or shortages.

103
00:10:01.660 --> 00:10:09.500
And already you see why it is that in a market economy you never have any surplus or shortage.

104
00:10:09.500 --> 00:10:13.220
In a so-called planned economy, in socialist economies or semi-socialist economies, one

105
00:10:13.220 --> 00:10:18.220
of the great features, great, one of the important features of them is constant problems of shortages

106
00:10:18.220 --> 00:10:19.220
and surpluses.

107
00:10:19.220 --> 00:10:23.940
I remember, and this is not particularly important, but it just sticks in my mind, I remember

108
00:10:23.940 --> 00:10:27.860
Newsweek had mentioned that many years ago, all of a sudden in Russia they had a toothbrush

109
00:10:27.860 --> 00:10:28.860
shortage.

110
00:10:28.860 --> 00:10:30.580
Why a toothbrush shortage?

111
00:10:30.580 --> 00:10:37.100
Well, the bristles were in omsk and the handles were in pumpsk and somehow they never meshed

112
00:10:37.100 --> 00:10:39.140
the two things.

113
00:10:39.140 --> 00:10:43.540
They forgot or whatever it is overlooked and they couldn't bring the bristles and the handles

114
00:10:43.540 --> 00:10:44.540
together.

115
00:10:44.540 --> 00:10:46.040
It took weeks or months to do it.

116
00:10:46.040 --> 00:10:52.100
So this is just typical, constant series and so-called planned economies of unexplained

117
00:10:52.100 --> 00:10:53.100
shortages.

118
00:10:53.100 --> 00:10:55.780
How come there's no Hershey Boris today?

119
00:10:55.780 --> 00:10:56.780
Who knows?

120
00:10:56.780 --> 00:10:57.780
Whatever.

121
00:10:57.780 --> 00:11:03.780
So this is, and you will see later in countries which have a lot of price control, maximum price control, which we'll get to a little later,

122
00:11:03.780 --> 00:11:12.780
there's always shortages too, and if you're in a price control type country, it's wise if you find anything you like on the shelf to buy as much as you can of it and hoard it,

123
00:11:12.780 --> 00:11:14.780
because you ain't going to see it very often.

124
00:11:14.780 --> 00:11:21.780
A friend of mine used to teach in Vancouver, British Columbia, and they had severe price controls.

125
00:11:21.780 --> 00:11:26.780
He's a great fan of Hershey chocolate syrup, which of course is very bad for you, that's another point.

126
00:11:26.780 --> 00:11:31.780
So anytime you see Hershey chocolate syrup on the shelves in the Banker, we buy, you know, 20 cans.

127
00:11:31.780 --> 00:11:38.780
If you go to visit them, you open this cupboard and there's 50 cans of Hershey chocolate syrup and almost nothing else.

128
00:11:38.780 --> 00:11:41.780
Anyway, we'll get to that a little later. Yeah?

129
00:11:45.780 --> 00:11:49.780
The Banker exists just so you can't... the mechanism isn't there to clear the market.

130
00:11:49.780 --> 00:11:54.780
It just stays at the controlled price. Yeah.

131
00:11:54.780 --> 00:11:59.780
I'll get to that a little bit later. Right now I want to point out what happens with the free market. I'll get back to that at length.

132
00:11:59.780 --> 00:12:08.780
They're stuck either below or above the free market price. Exactly. Then you have black markets and all sorts of other phenomenon-type places.

133
00:12:08.780 --> 00:12:18.780
Anyway, this is just a teaser for later on, a little bit later. Right now I just want to show what happens with the free market before we get into the government intervention.

134
00:12:18.780 --> 00:12:29.780
So what you see is that everybody is collaborating here to try to get at the equilibrium price.

135
00:12:29.780 --> 00:12:34.420
And because this is a benefit of everybody, especially entrepreneurs here, to try to eliminate

136
00:12:34.420 --> 00:12:35.420
shortages or surpluses.

137
00:12:35.420 --> 00:12:41.780
And so this is a built-in mechanism to get here and to stay there, get here once you're

138
00:12:41.780 --> 00:12:43.380
displacing it, back to it.

139
00:12:43.380 --> 00:12:47.780
Okay, so now we have the important truth, we just single, yeah?

140
00:12:47.780 --> 00:12:51.780
How do you reach, or how does the company reach Point of Effect 11?

141
00:12:51.780 --> 00:12:53.780
How do they know where the point is?

142
00:12:53.780 --> 00:12:55.780
They know there's no unsold surplus, there's no other word.

143
00:12:55.780 --> 00:12:58.780
How do they know it's in the beginning? They just want to try a product.

144
00:12:58.780 --> 00:13:00.780
Yeah. Oh, at the beginning?

145
00:13:00.780 --> 00:13:02.780
Yeah. When you find out it's trial and error.

146
00:13:02.780 --> 00:13:05.780
In other words, you set a price, you don't know what's going to happen.

147
00:13:05.780 --> 00:13:10.780
If you find out, let's say a new thing is, thing, whatever it is, thingamabob is producing,

148
00:13:10.780 --> 00:13:14.780
if you set the price as $8, you find out nobody buys it.

149
00:13:14.780 --> 00:13:23.780
You go back and you lower the price. If you finally get to the point where people only buy at a price below cost, then you're out of business.

150
00:13:23.780 --> 00:13:31.780
I know you're making minimal losses and that's it. If, on the other hand, you find a lot of people buy for $5, then you're happy to get a $5.

151
00:13:31.780 --> 00:13:38.780
If you sort of test it, you find out, gee, the shelves are running out. All of a sudden they disappear at $5 and you raise it to $6.

152
00:13:38.780 --> 00:13:45.780
There's no magic formula here. The thing to keep emphasizing is, it's not like in the textbooks where you're given the demand curve.

153
00:13:45.780 --> 00:13:49.780
Nobody knows what the demand curve is. They're trying to find out, especially with a new product that's very difficult.

154
00:13:49.780 --> 00:13:56.780
Of course, you have competitors and they're trying to find that, and you wind up in this kind of process where you settle on an equilibrium point.

155
00:13:56.780 --> 00:14:02.780
But I'd say there's a great test, immediate test, namely if you find out nobody has a big unsold surplus, you know the price is too high.

156
00:14:02.780 --> 00:14:08.660
If you find out there's a shortage, in other words, a thing disappears quickly, then it's

157
00:14:08.660 --> 00:14:11.900
obviously a signal that you can raise the price without any problem.

158
00:14:11.900 --> 00:14:17.460
So that's the immediate feedback you get, whether the stuff is not being sold.

159
00:14:17.460 --> 00:14:20.260
This is true not just for consumer goods, but for also producers' goods, you know, down

160
00:14:20.260 --> 00:14:22.460
the line, if you're producing raw material or something.

161
00:14:22.460 --> 00:14:25.780
If you find out you're not being sold, you have to lower the price.

162
00:14:25.780 --> 00:14:26.780
Yeah?

163
00:14:26.780 --> 00:14:38.780
Will better companies just have a high total revenue if we have surplus, rather than a few million points?

164
00:14:40.780 --> 00:14:47.780
Let me say before, the demand curve is that they might have a high total revenue even though they don't have surplus

165
00:14:56.780 --> 00:15:02.780
They'll benefit by any sale of it. I mean, maybe in the future they'll say, well, Jean, we're not going to produce less. We'll tap a higher revenue.

166
00:15:02.780 --> 00:15:08.780
But once you've produced it, then you're stuck. I mean, you've already spent the money on this thing. You try to get sell-off as much as you can.

167
00:15:08.780 --> 00:15:13.780
Nobody's going to benefit by piling up unsold Wonder Bread or unsold TV sets.

168
00:15:13.780 --> 00:15:18.780
What you're talking about is a future decision of how much to produce in the future.

169
00:15:18.780 --> 00:15:24.780
Right now we're talking about a day-to-day situation. Once given the amount produced, what happens? How does the price set?

170
00:15:24.780 --> 00:15:31.780
We'll get to that later on, how you decide what's going to be, how much to produce for the next year or next time period.

171
00:15:40.780 --> 00:15:49.780
So we have this built-in mechanism for arriving at the free market price, and it will be the intersection point.

172
00:15:54.780 --> 00:16:02.860
And then the question is, well if this is true, I think it is, why do prices ever change?

173
00:16:02.860 --> 00:16:04.540
Why isn't every price the same forever?

174
00:16:04.540 --> 00:16:09.420
Now obviously the reason why prices haven't changed for one or two reasons, or both, namely

175
00:16:09.420 --> 00:16:11.940
either the demand curve changes or the supply changes.

176
00:16:11.940 --> 00:16:17.540
The only way in which any price can change over time is a change in one of these two

177
00:16:17.540 --> 00:16:22.420
underlying factors, or both, because in order to analyze both you have to analyze each one,

178
00:16:22.420 --> 00:16:33.260
Let's look then at what happens with supply changes easier. For example, let's say usually

179
00:16:33.260 --> 00:16:38.660
about every five years there's a big frost in Brazil, which is our major coffee producer,

180
00:16:38.660 --> 00:16:43.380
and a big frost and it kills half the coffee plants. So there's a big drop in the supply

181
00:16:43.380 --> 00:16:47.300
of coffee, in other words, how much coffee comes on the market say next month or whatever.

182
00:16:47.300 --> 00:16:55.300
So the supply curve shifts to the left. I'm making this dash in order to show the change here.

183
00:16:56.300 --> 00:17:01.300
So you have a drop in the, a lowering of the supply of this product.

184
00:17:02.300 --> 00:17:09.300
What happens? It means that the old price, the old equilibrium price, let's say it used to be, it used to be a dollar a pound back in the good old days, not too long ago.

185
00:17:09.300 --> 00:17:22.300
It means that the old price, the supply has suddenly lowered, so it means that with a new supply, you now have a shortage.

186
00:17:22.300 --> 00:17:34.300
In other words, demand, which used to be that demand and supply were cleared at a dollar a pound, all of a sudden you find since the supply has been lowered, that the shortage has opened up.

187
00:17:34.300 --> 00:17:41.300
There's a shortage, there's now a situation where people can't find the product at a dollar a pound, so the price goes up.

188
00:17:41.300 --> 00:17:52.300
The price is bid up by the buyers, so finally it reaches whatever, say $1.50 a pound, and the new equilibrium price again clear the market.

189
00:17:52.300 --> 00:17:59.300
In other words, demand again becomes excess demand, and demand and supply are now cleared at the higher price.

190
00:17:59.300 --> 00:18:02.300
So a higher price clears the market.

191
00:18:02.300 --> 00:18:09.300
This demonstrates the two functions that the price system performs in the market.

192
00:18:09.300 --> 00:18:12.300
Most people understand one function, they don't understand the other.

193
00:18:12.300 --> 00:18:15.300
One is the incentive function, we'll get to that later on.

194
00:18:15.300 --> 00:18:23.300
In other words, if the price is higher, people will produce more over the longer run.

195
00:18:23.300 --> 00:18:32.900
If you offer, well, just to give you an idea, they used to be, 1948, I think it was 1948,

196
00:18:32.900 --> 00:18:40.300
when there was only one atomic energy consumer, namely the US government, and I think it was called the Atomic Energy Commission,

197
00:18:40.300 --> 00:18:44.800
they were trying to find uranium, there was a quote, uranium shortage, couldn't find any uranium, they were going crazy,

198
00:18:44.800 --> 00:18:50.200
you can't get, uranium is gone, we can't produce any more atom bombs, the world is going to come to an end or whatever,

199
00:18:50.200 --> 00:18:54.800
Aside from whether or not they should be producing more atom bombs, it's another philosophic question.

200
00:18:54.800 --> 00:19:00.200
Some economists down there finally said, look turkeys, double the price you're offering.

201
00:19:00.200 --> 00:19:05.700
There's only one buyer, the US government, they're offering whatever it was per ton of uranium.

202
00:19:05.700 --> 00:19:10.200
Double the price and see what happens. They double the price, and all of a sudden everybody's out there with that Geiger counter,

203
00:19:10.200 --> 00:19:14.200
the famous uranium boom. Out on the west with the Geiger counter.

204
00:19:14.200 --> 00:19:18.200
By God, there was no uranium shortage. They found lots of uranium, and all they had to do was double the price offer

205
00:19:18.200 --> 00:19:25.200
The stuff is out there. Whatever the stuff is, you have to offer a higher price to induce them to go out and look for it.

206
00:19:25.200 --> 00:19:34.200
Most people sort of understand this. Not everybody understands this. If you offer a higher price for something, you'll probably get greater supply and vice versa.

207
00:19:34.200 --> 00:19:38.200
The thing they don't understand at all is what you can call the rationing function.

208
00:19:38.200 --> 00:19:47.200
In other words, the reason why everything has a price at all is because it's not unlimited.

209
00:19:47.200 --> 00:20:04.200
The universal fact of scarcity, everything is scarce. Some things are scarcer than others. If something were unlimited, it'd be free, like air, presumably. Water used to be before water shortages. So they're quote free unquote, almost close to it.

210
00:20:04.200 --> 00:20:09.160
But coffee is not free, coffee is scarce, like everything else and the things that produce

211
00:20:09.160 --> 00:20:10.160
coffee are scarce.

212
00:20:10.160 --> 00:20:16.140
If they get scarcer, that means the pricing performs a rationing function.

213
00:20:16.140 --> 00:20:19.860
Pricing of anything performs a function of squeezing out the sub-marginal buyers, people

214
00:20:19.860 --> 00:20:23.440
who don't want to spend a buck a pound, they'll only drink coffee if it's 20 cents a pound.

215
00:20:23.440 --> 00:20:28.820
If it's not a pound, they'll drink something else, water or cocoa, whatever it is.

216
00:20:28.820 --> 00:20:31.320
So the point is that prices perform a rationing function.

217
00:20:31.320 --> 00:20:35.320
If the thing becomes scarcer, the prices have to ration even more.

218
00:20:35.320 --> 00:20:45.320
And so, by the price going up, it performs the function of squeezing out marginal buyers, marginal buyers, those who are close to the edge of buying coffee.

219
00:20:45.320 --> 00:20:53.320
What happened a few years ago, the prices of coffee doubled, almost overnight, because of the big drop in supply, big increase in price,

220
00:20:53.320 --> 00:21:00.320
and people started buying, they bought less coffee, almost permanently. They cut the amount of coffee they drank, some people shifted permanently to tea,

221
00:21:00.320 --> 00:21:11.320
And the result of all this was they voluntarily restricted their purchases. Some people bought the same amount of coffee, some people were coffee freaks and said, how will I spend more money on it?

222
00:21:11.320 --> 00:21:19.320
Others, however, are only marginal coffee buyers and they cut their consumption. So the result of all that is a voluntary rationing process.

223
00:21:19.320 --> 00:21:25.320
The alternative to voluntary rationing is government rationing, which we'll get to later too.

224
00:21:25.320 --> 00:21:29.760
In World War Two, the government orders, gives you, issues tickets, personally hires hundreds

225
00:21:29.760 --> 00:21:33.620
of thousands of people to issue ticket books, and of course all this stuff, ration books,

226
00:21:33.620 --> 00:21:38.380
which they did during World War Two, and everybody's can, you know, you have only ten coupons a

227
00:21:38.380 --> 00:21:43.080
week to buy coffee, ten pounds a week or something, and then there's a whole hassle, and in addition

228
00:21:43.080 --> 00:21:48.220
to paying for the coffee and money, you also have to pay the ration tickets, a total mess.

229
00:21:48.220 --> 00:21:52.720
At any rate, but there is compulsory, it means you would buy more than ten, whatever it is,

230
00:21:52.720 --> 00:21:59.720
A drop in supply of x leads to an increase in the price of x.

231
00:22:22.720 --> 00:22:33.720
Okay, the opposite happens. In economics, almost all laws are symmetrical.

232
00:22:33.720 --> 00:22:50.720
Look at the other side of the coin.

233
00:22:50.720 --> 00:23:20.720
Okay, here we have coffee flowing back in, you have a big increase in coffee production, the climate's better, whatever it is, right, so you increase fertilizer, different techniques, so the supply of coffee goes up, this means that at the old price, where demand and supply are equal, all of a sudden you have a bigger supply now, you have sort of X amount of coffee, you have more than that, this means that at the greater supply, at the old price you now have

234
00:23:20.720 --> 00:23:27.720
the excess surplus, the unsold surplus of supply here, because supply has increased,

235
00:23:27.720 --> 00:23:32.720
it's still up at this price. It means in order to induce people to buy more than whatever

236
00:23:32.720 --> 00:23:36.720
100,000 pounds of coffee, whatever it happens to be, in order to induce people to buy more,

237
00:23:36.720 --> 00:23:40.720
you have to cut the price. And as you cut the price, they're now willing to buy the

238
00:23:40.720 --> 00:23:47.160
excess, the increased supply. And so the price falls to get back to a new equilibrium point

239
00:23:47.160 --> 00:23:51.880
where supply and demand are again equal.

240
00:23:51.880 --> 00:23:55.200
So this is, in other words, you eliminate the excess supply and you wind up

241
00:23:55.200 --> 00:23:58.640
with supply and demand being equal.

242
00:23:58.640 --> 00:24:05.120
So we conclude that an increase in the supply of X will lead to a drop in the price.

243
00:24:05.120 --> 00:24:10.120
And this is what happens. Of course, the coffee thing is a beautiful example. This happens all the time.

244
00:24:10.120 --> 00:24:11.480
The coffee,

245
00:24:11.480 --> 00:24:14.120
the frost in the coffee, in Brazil,

246
00:24:14.120 --> 00:24:18.080
Drop in supplies, an increase in price, and a couple years later the source is gone

247
00:24:18.080 --> 00:24:20.680
Supply increases and the price drops again

248
00:24:20.680 --> 00:24:22.480
So this is almost a

249
00:24:22.480 --> 00:24:24.520
textbook case, but it happens all the time

250
00:24:24.520 --> 00:24:26.400
all sorts of products

251
00:24:28.200 --> 00:24:30.400
Agriculture is a good example

252
00:24:30.400 --> 00:24:35.600
because in agriculture you have full, actual full supply, you don't have that much in other things

253
00:24:35.600 --> 00:24:36.920
in most things

254
00:24:36.920 --> 00:24:39.820
supply increases over time

255
00:24:39.820 --> 00:24:46.160
with agriculture, of course, it's more in the lap of the gods than other products

256
00:24:46.160 --> 00:24:49.260
but in general

257
00:24:49.260 --> 00:24:54.920
supply increases, in general you have an increase in supply of almost everything

258
00:24:54.920 --> 00:24:59.460
in that case, if that's true, which it is, you should have generally falling prices

259
00:24:59.460 --> 00:25:03.300
in other words, over time

260
00:25:03.300 --> 00:25:05.180
supply increases

261
00:25:05.180 --> 00:25:07.200
price falls

262
00:25:07.200 --> 00:25:12.400
By the way, this is not to lead to lower profits, because costs fall also, as we'll see later on.

263
00:25:12.400 --> 00:25:15.640
In other words, there's a general increase in productivity and costs fall,

264
00:25:15.640 --> 00:25:20.720
and so it doesn't mean you're squeezing firms or anything like that.

265
00:25:20.720 --> 00:25:22.240
So you've got, then,

266
00:25:22.240 --> 00:25:25.480
a situation where most prices should be falling, and yet,

267
00:25:25.480 --> 00:25:29.060
and yet, of course, as we all know, prices are almost always going up.

268
00:25:29.060 --> 00:25:32.860
Even now, and it's supposed to be the end of inflation, this is a macro,

269
00:25:32.860 --> 00:25:36.760
we discuss this in macros, there's only a macro concept,

270
00:25:36.760 --> 00:25:42.760
but uh... even now when the inflation is supposed to be over, it's still going up, prices are still going up about three or four percent a year

271
00:25:42.760 --> 00:25:44.680
this is when the inflation is supposed to be over

272
00:25:44.680 --> 00:25:47.400
uh... it's over only in the sense of

273
00:25:47.400 --> 00:25:50.920
five, six years ago prices were going up by fourteen percent a year

274
00:25:50.920 --> 00:25:54.680
so if it's true that supply usually goes up, how come prices are going up?

275
00:25:54.680 --> 00:25:56.840
and that's a good question, the answer is

276
00:25:56.840 --> 00:26:00.520
there's nothing to do with this good stuff, goods are going up, increasing

277
00:26:00.520 --> 00:26:01.960
the answer is with money

278
00:26:01.960 --> 00:26:06.120
and the fact that the manures are always going up because the government is printing money and pouring it in

279
00:26:06.120 --> 00:26:18.560
And in fact, in general, from the beginning of the Industrial Revolution, in other words,

280
00:26:18.560 --> 00:26:27.040
from about 1780, let's say, or 1800, until 1940, prices fell all the time, every year

281
00:26:27.040 --> 00:26:33.280
prices would fall a bit, except during wartime, during the War of 1812, the Civil War, World

282
00:26:33.280 --> 00:26:36.720
World War I and World War II, the government printed a lot of money in order to pay for

283
00:26:36.720 --> 00:26:37.720
the war effort.

284
00:26:37.720 --> 00:26:38.720
Of course, prices went up.

285
00:26:38.720 --> 00:26:43.080
All the other times, that was during peacetime, prices generally fell.

286
00:26:43.080 --> 00:26:50.000
The difference now is there's a different money system that's come in since the 1930s.

287
00:26:50.000 --> 00:26:54.960
A totally inflationary monetary system has now taken over of the government's printing

288
00:26:54.960 --> 00:27:01.320
factory, printing press, counterfeiting printing press factories down in Washington.

289
00:27:01.320 --> 00:27:07.320
For example, all of you are probably alive to this, namely, computers, of course, computers

290
00:27:07.320 --> 00:27:13.280
start off extremely expensive and now are very cheap, they keep getting cheaper, for

291
00:27:13.280 --> 00:27:21.080
a while they're getting cheaper every week. Calculators, which I remember the first time

292
00:27:21.080 --> 00:27:26.080
I saw a hand calculator, it wasn't too long ago, maybe 10 years ago or something, and

293
00:27:26.080 --> 00:27:30.320
I think it was about 10-12 years ago, right? It was on the elevator here and one of my

294
00:27:30.320 --> 00:27:37.320
One of my friends in the EE department, and he said, look, we have this magic thing, a new product, and all we have to do is to punch these buttons and multiply them and all that.

295
00:27:37.320 --> 00:27:41.320
I said, Jesus, that's fantastic. He said, yeah, it's only $500. I got a discount.

296
00:27:41.320 --> 00:27:50.320
So the capital assistance is so fantastic that right now we have a lot better calculators for $18.

297
00:27:50.320 --> 00:27:56.320
So this is what happens when the economy is given its head, so to speak, with very little interference.

298
00:27:56.320 --> 00:28:05.320
And you have a fantastic increase of production, productivity, increase in quality, and a huge drop in price.

299
00:28:05.320 --> 00:28:07.320
Same thing happened with TV sets.

300
00:28:07.320 --> 00:28:11.320
The first TV sets were around 1948, 1950.

301
00:28:11.320 --> 00:28:16.320
They were murky, not only were they black and white, they were, we can hardly see anything.

302
00:28:16.320 --> 00:28:18.320
Very murky images.

303
00:28:18.320 --> 00:28:20.320
Of course, there's no cable either.

304
00:28:20.320 --> 00:28:27.320
and of course about 2,000 bucks, the whole neighborhood is sitting around gazing at these little flickering images

305
00:28:27.320 --> 00:28:34.320
so now you have, even with inflation, even the fact that the dollar is worth one-fifth, let's say what it was in 1948

306
00:28:34.320 --> 00:28:42.320
even so the prices are fantastically smaller and much higher quality, normally you have to take price per unit quality

307
00:28:42.320 --> 00:29:00.160
This is what can be done in a free market system, even with, as I say, the government

308
00:29:00.160 --> 00:29:12.040
printing press, which turns on, which makes prices in general, higher.

309
00:29:12.040 --> 00:29:16.080
So in other words, with the supply changes, you don't have supply increases, you'll have

310
00:29:16.080 --> 00:29:24.160
a supply drop, you have an increase in price, and supply increases, you have a fall in price.

311
00:29:24.160 --> 00:29:28.640
And now one thing I'm going to stress here, which I always, every micro teacher always

312
00:29:28.640 --> 00:29:33.600
stresses on this, and always makes the point, and always says that half of students at least

313
00:29:33.600 --> 00:29:37.520
will get this wrong on a test, and they're always right, even though it seems to be a

314
00:29:37.520 --> 00:29:38.520
simple point.

315
00:29:38.520 --> 00:29:41.600
It seems to be something which can be very difficult to get through to the head of students.

316
00:29:41.600 --> 00:29:47.640
namely, a difference between when you increase supply, for example, you're going down the

317
00:29:47.640 --> 00:29:53.240
existing demand curve. The demand curve is defined as a locus of responses to price.

318
00:29:53.240 --> 00:29:57.040
In other words, given the price of so-and-so, how much will be purchased? That's what the

319
00:29:57.040 --> 00:30:01.560
demand curve is. So therefore, the one thing which can't change the demand curve is a change

320
00:30:01.560 --> 00:30:05.680
in price. The one thing which can't change the demand curve by definition is a change

321
00:30:05.680 --> 00:30:14.080
The demand curve is constructed, defined as, or constructed as, responses to price.

322
00:30:14.080 --> 00:30:19.240
So if you have an increase in supply, it does not increase the demand curve, it increases

323
00:30:19.240 --> 00:30:25.520
the quantity demanded going down the existing demand curve, okay, because this is the curve

324
00:30:25.520 --> 00:30:26.520
itself.

325
00:30:26.520 --> 00:30:33.120
As the supply drops, you're going up the existing demand curve, the demand curve as a whole

326
00:30:33.120 --> 00:30:34.120
doesn't shift.

327
00:30:34.120 --> 00:30:37.820
You're going up, you're decreasing the quantity of money because you're going up the same demand curve.

328
00:30:37.820 --> 00:30:40.420
We haven't gotten to the shifts in the demand curve yet. That's the next step.

329
00:30:40.420 --> 00:30:49.120
I just want to point out that the change in price will only go up or down existing given the demand curve by definition.

330
00:30:49.120 --> 00:30:53.120
Okay, that's a change in supply.

331
00:30:53.120 --> 00:30:57.120
The other thing which can change is the demand curve.

332
00:30:57.120 --> 00:31:02.120
In other words, the demand curve can shift.

333
00:31:02.120 --> 00:31:06.120
So why would a demand curve shift? Well, it doesn't shift because of the responsive price, as I said.

334
00:31:06.120 --> 00:31:12.120
There's one thing you can't shift in response to, because that's how it's defined.

335
00:31:12.120 --> 00:31:20.120
It can shift because of the inflation. In other words, if a government prints more money and spends it so everybody gets more money,

336
00:31:20.120 --> 00:31:27.120
they'll have more money to pay and buy on everything. That means the demand curve as a whole will shift. Every demand curve will shift upward.

337
00:31:27.120 --> 00:31:36.120
In other words, at any given price, everybody will spend more money or try to buy more goods at any given price.

338
00:31:36.120 --> 00:31:42.120
In other words, the man-curve of the whole shifts upward and to the right.

339
00:31:42.120 --> 00:31:49.120
So this is an upward shift. In other words, everybody is willing to spend more for any given price because everybody's got more money.

340
00:31:49.120 --> 00:31:53.120
Let's say the government prints twice as much money and gives it to everybody.

341
00:31:53.120 --> 00:32:23.120
One of my favorite examples I call the Angel Gabriel model, which is David Hume, a similar model, he didn't call it the Angel Gabriel model, but anyway, essentially he said what happens if an angel comes at night and doubles everybody's supply of money, by magic, and everybody's got twice as much money, they go and of course they spend, everybody's now willing to spend a lot more on everything, so the man curve shifts upward and to the right, of course prices will then double more or less on the end of it, but that was Hume's point.

342
00:32:23.120 --> 00:32:28.120
We don't get into that part of it here. It's, again, a macro point.

343
00:32:28.120 --> 00:32:36.120
But again, the situation is that the man curve as a whole, if everybody's got more money in their pocket, the man curve will go up.

344
00:32:36.120 --> 00:32:42.120
If the other half people have less money in their pocket, the man curve will shift downward. In other words, downward and to the left.

345
00:32:42.120 --> 00:32:46.120
It will spend less money on any given item.

346
00:32:46.120 --> 00:32:59.880
This will also happen, for example, if taxes go up, if the big income tax increase, just

347
00:32:59.880 --> 00:33:04.480
looking at the tax payers, they'll have less money in their pocket, all of the demand curves

348
00:33:04.480 --> 00:33:07.360
will shift, they'll go downward and to the left, they won't have the money to spend,

349
00:33:07.360 --> 00:33:08.360
very simple.

350
00:33:08.360 --> 00:33:11.120
If there's a big tax cut, the demand curve will shift upward.

351
00:33:11.120 --> 00:33:14.440
Again, we're not going to go too much into that because that's a macro point, but I'm

352
00:33:14.440 --> 00:33:21.440
I'm going to point out that demand curves, part of the thing that influences demand curves is how much money people have in their pockets.

353
00:33:21.440 --> 00:33:29.440
Okay, for individual goods and services, demand curves will shift on the basis of value scale changes.

354
00:33:29.440 --> 00:33:37.440
So that these value scales change all the time on the basis of fashion, preferences, whatever.

355
00:33:37.440 --> 00:33:46.440
For example, in the United States in the last 40 years, there's been a big shift in values of preferences by consumers on the wine and whiskey front.

356
00:33:46.440 --> 00:33:57.440
A big shift out of so-called heavy liquors and into so-called light stuff, either because people want to lose weight or whatever it is.

357
00:33:57.440 --> 00:34:08.240
In other words, there's been a big shift away from bourbon, and scotch, and especially rye whisky.

358
00:34:08.240 --> 00:34:10.640
As a matter of fact, when I was growing up, everyone was drinking blended whisky.

359
00:34:10.640 --> 00:34:12.640
Almost nobody makes blended whisky anymore.

360
00:34:12.640 --> 00:34:14.240
Blended.

361
00:34:14.240 --> 00:34:18.040
So these things are going way down. The man curves have shifted way down for those.

362
00:34:18.040 --> 00:34:23.640
On the other hand, vodka and gin have gone way up.

363
00:34:23.640 --> 00:34:34.640
The wine front has been a big shift away from red wine, and a big shift in favor of white wine. Enormous.

364
00:34:34.640 --> 00:34:42.640
So you have so-called yuppies, for example, known as the white wine and quiche set.

365
00:34:42.640 --> 00:34:46.640
So as a matter of fact, it's been a shift away from alcohol until we had white wine all together.

366
00:34:46.640 --> 00:34:51.640
Huge increase in wine. Forty years ago, nobody drank white wine because it was almost unheard of.

367
00:34:51.640 --> 00:35:21.600
So at any rate, these things reflect, this means of course, in the man curve front, which you have is a, means to say bourbon, the man curve for bourbon goes down, means people are now, means that the old prices will fall, that the old prices are, there's now a surplus, unsold surplus applied greater than the man,

368
00:35:21.640 --> 00:35:37.640
The price will have to fall immediately. On the other hand, say with vodka or white wine, there's a big increase in demand curve, the whole demand curve shifts upward, and it means the old price is now a shortage, so the price will go up.

369
00:35:37.640 --> 00:35:47.640
So, in other words, an increase in demand curve for X, where the whole curve shifts upward,

370
00:35:47.640 --> 00:35:52.640
and when we just use the phrase of the word increase in demand, it means the entire demand curve.

371
00:35:52.640 --> 00:36:00.640
It does not mean this thing here when supply goes up, say, and your quantity of demand increases.

372
00:36:00.640 --> 00:36:04.640
If you just use the phrase increase in demand, it first means the entire curve.

373
00:36:04.640 --> 00:36:10.140
It means that at any given price people will buy more of it than they did before, that's what it means, okay?

374
00:36:10.140 --> 00:36:20.140
So it means that the entire demand curve goes up, from here to here, and an increase in demand for X will yield an increase in price of X.

375
00:36:20.140 --> 00:36:29.140
On the other hand, a drop in the demand for X, say for bourbon, will yield a drop in the price.

376
00:36:29.140 --> 00:36:37.140
If people will not buy the same amount, they'll buy less at any given price, they'll not buy at the old price, they'll buy less than they did before, they'll unsold surplus.

377
00:36:37.140 --> 00:36:45.140
The result of this, the impact of this, these demand changes, will result in changes in supply.

378
00:36:45.140 --> 00:36:51.140
Now we get to what causes people, producers, to produce a thing in the first place.

379
00:36:51.140 --> 00:36:56.140
So far we've been talking about supply being given. Supplies 100,000 loads or whatever and that's it.

380
00:36:56.140 --> 00:37:00.140
Let me begin to talk about what the determinants apply. Why do producers produce 100,000 to begin with?

381
00:37:00.140 --> 00:37:02.140
How do they determine how much to produce?

382
00:37:02.140 --> 00:37:06.140
The next step we'll get to is how these demand changes impact on that.

383
00:37:06.140 --> 00:37:09.140
Okay, let's take a 10-minute break and we'll go back.

384
00:37:09.140 --> 00:37:15.140
Let's turn to the first step, namely, why are decisions made to produce as much as are being produced?

385
00:37:15.140 --> 00:37:20.140
Why do they decide to produce 100,000 loaves of Wonder Bread and not 50,000 or 200,000?

386
00:37:26.140 --> 00:37:41.620
Okay, let's see what happens here, fire please, price, quantity, supply, demand, let's take

387
00:37:41.620 --> 00:37:46.460
a situation where demand changes, demand increases for vodka or whatever, white wine, whatever

388
00:37:46.460 --> 00:37:47.460
happens to be.

389
00:37:47.460 --> 00:37:53.300
So is a permanent, well first of all businessmen have to decide is this a glitch in the system

390
00:37:53.300 --> 00:38:02.300
And that's something that has to be done by insight until the price goes up because of the increase in demand.

391
00:38:02.300 --> 00:38:04.300
The new equilibrium price is now higher.

392
00:38:04.300 --> 00:38:11.300
And it has to be decided, for example, the guys are lucked out into cabbage patch dolls.

393
00:38:11.300 --> 00:38:15.300
People have been producing dolls for 80 years, and nothing much happened.

394
00:38:15.300 --> 00:38:18.300
All of a sudden a cabbage patch doll hits.

395
00:38:18.300 --> 00:38:21.300
Unbelievable. Tremendous demand for it.

396
00:38:21.300 --> 00:38:51.300
Remember, one guy, the great thing is one guy from Pennsylvania actually flew to London to get it at a, to get it, it was a big shortage, and the question is, the cabbage patched off, people had to decide in the following year, is this a temporary thing, a blinding blaze which will be going on next year or not, while it still continued a certain, you know, fell off a little bit, so they had to decide, is this sort of a permanent thing, okay, with white wine, they figure vodka, yes it is, and so what then happens is,

397
00:38:51.300 --> 00:38:56.300
Well, this is going to be a permanent increase in demand. Tastes are changing, basically, etc., etc.

398
00:38:56.300 --> 00:39:01.300
Then they will gear up and produce more vodka for the future. In other words, they start changing the situation,

399
00:39:01.300 --> 00:39:06.300
getting white grapes instead of red grapes for the white wine, and they gear up.

400
00:39:06.300 --> 00:39:13.300
And how long this takes depends on the technological situation, depends on how long it takes to produce more vodka,

401
00:39:13.300 --> 00:39:20.300
more white wine, or more calculators, or whatever. So the length of time depends on the technology of the product.

402
00:39:20.300 --> 00:39:30.900
At any rate, it means that over time, because the increase of price means more profits, it means that there's a greater price per product being sold than before.

403
00:39:30.900 --> 00:39:36.600
They gear up and they produce more of it. So over the years, supply curve will then shift.

404
00:39:36.600 --> 00:39:43.400
In other words, next year's supply line will be higher, to the right, shifting to the right, et cetera, et cetera.

405
00:39:43.400 --> 00:39:52.400
You wind up, let's say, after about a few years, with a permanently new supply curve, which is now, which reflects the increase in demand for vodka.

406
00:39:52.400 --> 00:40:06.400
In other words, so this means you have a time period situation where, in year one, let's say, the price goes up.

407
00:40:06.400 --> 00:40:11.400
The first thing that happens, the demand curve for X goes up, this increases the price.

408
00:40:11.400 --> 00:40:17.640
A year later, the supply goes up a little bit in response to that, and so you have the price going down a little bit.

409
00:40:17.640 --> 00:40:27.640
Increase the supply of X, a drop in the price, and so forth and so on, until you get, say, to here, where the price is down, somewhere in between the initial one here and up there.

410
00:40:27.640 --> 00:40:32.640
And so, as the supply goes up, the price of it then falls over time.

411
00:40:32.640 --> 00:40:41.140
So what you have is a series of vertical increases of supply going like that, so finally you get a new final equilibrium point.

412
00:40:41.140 --> 00:40:47.140
In other words, this is a long run equilibrium point. It takes four years to five years, depending on how long it takes to gear up for all of this.

413
00:40:47.140 --> 00:40:57.140
So what you have is you wind up eventually with a permanent increase in supply and reflecting this permanent increase in demand for, say, white wine or vodka.

414
00:40:57.140 --> 00:41:01.140
On the other hand, let's take the falling demand.

415
00:41:01.140 --> 00:41:20.140
Bourbon, let's say, it was a fall in demand for bourbon, man curve for bourbon, and so they have a deep prime, the new curve goes like that.

416
00:41:20.140 --> 00:41:35.140
First you have a big drop as the surplus from the previous prices now, unsold surplus, you wind up with a lower price, a new equilibrium price is much lower.

417
00:41:35.140 --> 00:41:49.140
Then if the winemakers, the whisky makers believe this is going to be permanent, this reflects a permanent change, you drop it in half a red wine or bourbon, then over the years they will supply less of it, they will shift away from red wine into white wine, which of course is exactly what they've done.

418
00:41:49.140 --> 00:41:53.140
Much less red wine is being produced now than it used to be, much more white wine.

419
00:41:53.140 --> 00:41:56.140
It doesn't mean all red wine disappears, there's always a margin.

420
00:41:56.140 --> 00:41:59.140
It's a question of marginal changes.

421
00:41:59.140 --> 00:42:01.140
Less bourbon, more vodka.

422
00:42:01.140 --> 00:42:08.140
So what you have is a lower supply each year, and as the supply drops,

423
00:42:08.140 --> 00:42:12.140
the price goes up again until you wind up somewhere in the middle.

424
00:42:12.140 --> 00:42:18.140
So you have then over time, in response to the lower demand for red wine,

425
00:42:18.140 --> 00:42:29.140
You have a much lower supply, you have a lower price and a lower supply that allows you to wind up with a permanently lower supply as a response to the lower demand.

426
00:42:29.140 --> 00:42:39.140
In other words, over time, production of when entrepreneurs produce something, they're doing it in anticipation of selling it to the consumer, in anticipation of demand.

427
00:42:39.140 --> 00:42:46.140
If the demand rises and they realize they expect it, then they will produce more to meet that demand.

428
00:42:46.140 --> 00:42:50.140
If the demand falls, they realize and expect that means they'll produce less in response to that

429
00:42:50.140 --> 00:42:56.140
It means over time, consumers decide how much will be produced of everything

430
00:42:56.140 --> 00:43:00.140
If they like a product and they go for it in a big way, calculators, computers, or whatever

431
00:43:00.140 --> 00:43:04.140
a lot more will be produced, this huge shift of resources, land, labor, and capital

432
00:43:04.140 --> 00:43:07.140
into this new industry

433
00:43:07.140 --> 00:43:10.140
Even if, on the other hand, they don't like a product, they go away from it

434
00:43:10.140 --> 00:43:13.140
resources will flow out of the industry, out of red wine into white wine

435
00:43:13.140 --> 00:43:16.140
and why out of bourbon and into vodka and whatever.

436
00:43:16.140 --> 00:43:23.140
Of course you have, for example, before the calculator, I don't know if any of you have seen this,

437
00:43:23.140 --> 00:43:27.140
this is a technological museum somewhere, when I was going to college and taking statistics,

438
00:43:27.140 --> 00:43:34.140
they had what was called, I think multiplying machines is the name for it, I believe,

439
00:43:34.140 --> 00:43:40.140
and they were big bruisers, huge, very heavy, and you punch, they have a whole bunch of keyboard,

440
00:43:40.140 --> 00:43:49.140
and it took a long time, it took only slightly less time than doing it by pencil and that

441
00:43:49.140 --> 00:43:55.340
had a statistical lab which would take you hours to use these losers and they were obsolete,

442
00:43:55.340 --> 00:44:01.260
they were totally obsolesced by calculators and computers and so they should have.

443
00:44:01.260 --> 00:44:06.340
Some of these companies I think are no longer here, they are no longer producing that stuff,

444
00:44:06.340 --> 00:44:15.340
Burroughs, Frieden, those are the big names in these calculating machines. I guess they were cool.

445
00:44:15.340 --> 00:44:20.340
And so, less of them is produced. Right now, I guess zero is produced of that stuff.

446
00:44:20.340 --> 00:44:25.340
And they shift other, better products, which are demanded by consumers.

447
00:44:25.340 --> 00:44:28.340
In some cases, like the horse and buggy, there used to be millions of carriages being produced every year.

448
00:44:28.340 --> 00:44:33.340
There ain't no carriages except for the handsome cabs in a separate park. There's still a few.

449
00:44:33.340 --> 00:44:40.340
So over the long run, and the long run is that long, consumers decide by their demand curves, by their value scales and demand curves, how much should be put in, where resources should go into, where land, labor, capital, science, whatever, engineers, where they should focus their money.

450
00:45:03.340 --> 00:45:15.340
And it's decided by the price system, through the price system, through the man curves and profit and loss system, who's going to make profits where, and this reflects the intensity of demand by consumers.

451
00:45:15.340 --> 00:45:28.340
That's how the system works. That's how resources get funneled out of bourbon and into vodka, out of red wine and into white wine and so forth, out of calculating machines and into calculators, etc., etc., etc.

452
00:45:28.340 --> 00:45:38.980
Okay, so this is the, so the demand curves, prices can change either by an increase, either

453
00:45:38.980 --> 00:45:44.460
by change in supply or change in demand, if the supply increases, the price will fall,

454
00:45:44.460 --> 00:45:50.020
if the supply decreases, the price rises, if the demand curve increases, the price rises

455
00:45:50.020 --> 00:45:57.860
and will, if considered permanent, induce a greater increase, a long run increase in supply

456
00:45:57.860 --> 00:46:03.960
After the man-curve falls and is considered permanent, it will induce a long run stoppage supply.

457
00:46:03.960 --> 00:46:21.260
Now if you take this, any given product, and take this vertical curve, and if you look at, if the man-curve increases,

458
00:46:21.260 --> 00:46:27.260
And how much will, what will happen to supply as a result, and you wind up, let's say, here.

459
00:46:27.260 --> 00:46:34.260
If the main curve falls, what happens to supply as a result? It'll keep dropping until here.

460
00:46:34.260 --> 00:46:42.260
And if you connect these, if you connect these dots, you get what the textbook has as a forward-sloping supply curve.

461
00:46:42.260 --> 00:46:47.260
That's where that comes from. But this is a long-run supply curve.

462
00:46:47.260 --> 00:46:53.260
It reflects what happens if the price settles at any given point for a long period.

463
00:46:53.260 --> 00:46:56.260
This is how much will be produced.

464
00:46:56.260 --> 00:47:00.260
If the price settles at $1.50 a loaf of bread, I'll produce more of it.

465
00:47:00.260 --> 00:47:06.260
If the price settles at $75 a loaf, I'll produce less of it over the long run.

466
00:47:06.260 --> 00:47:09.260
The long run supply curve then is not the same thing as the man curve.

467
00:47:09.260 --> 00:47:13.260
It doesn't belong on the same graph. That's one of the basic problems with it.

468
00:47:13.260 --> 00:47:16.260
The man curve is instantaneous. It's a freeze-frame situation.

469
00:47:16.260 --> 00:47:21.260
Any given day, this is what the man curve is, is how much would be purchased at any given price.

470
00:47:21.260 --> 00:47:32.260
The vertical supply line is the equivalent, that belongs on the same graph, that's the freeze frame, that's essentially today's supply, how much is available at the store to be sold today.

471
00:47:32.260 --> 00:47:39.260
The long run supply, the long run upward sloping supply curve is a third dimension thing, it incorporates time in it.

472
00:47:39.260 --> 00:47:53.260
It's a long run situation which tells you how much will be produced. In other words, if over time, a lot more will be produced at a higher price, it'll be like that, if it'll only be a small increase in production at a higher price, it'll be something like that.

473
00:47:53.260 --> 00:48:03.260
It doesn't belong in the same graph. It's an interesting thing, but it's not relevant to immediate price determination. That's the problem with it.

474
00:48:03.260 --> 00:48:10.420
Also, the elasticity of supply doesn't make that much difference, but there's some interest.

475
00:48:10.420 --> 00:48:11.420
Most supply is elastic.

476
00:48:11.420 --> 00:48:15.860
I mean, if you offer a higher price, you'll get more, as I said, with uranium.

477
00:48:15.860 --> 00:48:19.860
But it hasn't got the same importance as the elasticity of demand, because total revenue

478
00:48:19.860 --> 00:48:21.340
doesn't depend on it.

479
00:48:21.340 --> 00:48:27.820
Of course, if you sell more at a higher price, you get a higher total revenue.

480
00:48:27.820 --> 00:48:32.060
You never have a lower total revenue at a higher price, with a supply curve.

481
00:48:32.060 --> 00:48:35.060
So it doesn't really have the same importance.

482
00:48:35.060 --> 00:48:39.340
So that's why when dealing with day-to-day demand curves, immediate real demand curves

483
00:48:39.340 --> 00:48:43.580
and supply curves, I deal with the vertical, whereas the forward sloping one is the long

484
00:48:43.580 --> 00:48:48.940
run, looking over time for different products.

485
00:48:48.940 --> 00:48:52.900
One thing is, which you can deal with right now, is there ain't almost no such thing as

486
00:48:52.900 --> 00:48:53.900
a vertical supply curve.

487
00:48:53.900 --> 00:48:57.900
Of course it's true in the long run.

488
00:48:57.900 --> 00:49:04.900
Rembrandt, there's not going to be any more Rembrandts being produced, because Rembrandt's dead, it's very simple.

489
00:49:04.900 --> 00:49:08.900
So the supply of Rembrandts is not only vertical right now, it's fixed forever.

490
00:49:08.900 --> 00:49:12.900
Except that you might lose a Rembrandt and it will go down.

491
00:49:12.900 --> 00:49:17.900
There's no way in which the supply of Rembrandts can increase, except if somebody forges a perfect forgery.

492
00:49:17.900 --> 00:49:21.900
It's very difficult, because the technology of detecting forgery for art is enormous.

493
00:49:21.900 --> 00:49:29.900
You have x-ray equipment, pigments, this is the whole science of architecture.

494
00:49:29.900 --> 00:49:34.900
There are very good forgers in the sense that they paint as well as Rembrandt does.

495
00:49:34.900 --> 00:49:38.900
They can forge it, but they can't really get away with it technologically.

496
00:49:38.900 --> 00:49:46.900
So the other things on the hand are usually much more, you can increase the supply if you want to do it.

497
00:49:46.900 --> 00:49:52.400
And there's plenty of stuff, and we'll get to this later on until we get to energy.

498
00:49:52.400 --> 00:50:00.900
Since 1890 there have been so-called experts in the field of oil who claim that in 10 years oil will run out, there ain't going to be no more oil left.

499
00:50:00.900 --> 00:50:07.900
They've been saying this since 1890, in other words the experts in 1890 said by 1900 there's going to be no more oil.

500
00:50:07.900 --> 00:50:16.400
Why do they say that? Because they take, it's very simple, I mean you can use mathematical models, but basically it's very simple.

501
00:50:16.400 --> 00:50:46.400
Very simple, what they do is this, they take proven reserves underground, okay, so proven reserves, I don't know, I haven't got the figure, let's say proven reserves are a billion barrels, alright, and then they say, well, they look at the annual use of oil, annual consumption of oil, they say, well, it's a hundred million barrels a year, annual consumption, so they conclude that, okay, it's very simple, they conclude in ten years the world's running out.

502
00:50:46.400 --> 00:50:49.400
It's a very simple extrapolation.

503
00:50:49.400 --> 00:50:54.300
The problem with it, and the same people more often have been saying this since 1890,

504
00:50:54.300 --> 00:50:59.600
the problem with it is that proven reserves don't mean a damn thing. Proven reserves are only what they've already mapped.

505
00:50:59.600 --> 00:51:03.700
They know exactly where the stuff is. There's plenty of stuff down there which you haven't mapped yet.

506
00:51:03.700 --> 00:51:09.700
And so when the price goes up, let's say for example,

507
00:51:09.700 --> 00:51:22.700
Let's say here's oil. Let's say we get to energy and detail later on, but let's say the supply starts going down for oil, and as the supply goes down, we know now what happens.

508
00:51:22.700 --> 00:51:27.700
Price goes up. As the price goes up, you have two effects now, the incentive effect and the rationing effect.

509
00:51:27.700 --> 00:51:32.700
The rationing effect means that people will buy less oil. The marginal oil buyers are going to disappear.

510
00:51:32.700 --> 00:51:35.700
That's of course exactly what happened in the late 70s.

511
00:51:35.700 --> 00:51:42.300
The price goes up, they start conserving, quote-unquote, they just buy less of it, they find ways to do it.

512
00:51:42.300 --> 00:51:47.700
You know, they say, gee, well, remember if we can't buy less of it, oil is essential in modern economy and all that stuff.

513
00:51:47.700 --> 00:51:54.800
This says nothing marginally, you can always buy less of something, just like with a subway, you can always have one less subway ride a week.

514
00:51:54.800 --> 00:51:57.800
And this adds up if you have a million people do it.

515
00:51:57.800 --> 00:52:09.800
So, the price goes up, you're going down the same demand curve, up the demand curve, in other words, with a lower quantity demanded, and with the price going up, there's more incentive to go out there and look for oil.

516
00:52:09.800 --> 00:52:13.800
Ah, the price of oil is higher, we're going to go start looking for it, and they go looking for it, and by God, they find it.

517
00:52:13.800 --> 00:52:19.800
There's lots of oil down there, just a question of price. It costs money to go and explore it, go for it, drill it, and all that sort of stuff.

518
00:52:19.800 --> 00:52:23.800
And as the price goes up, there's more incentive to go for it, and by God, they find it.

519
00:52:23.800 --> 00:52:28.800
And so what's been happening since 1890 is proven reserves keep going up even with the annual consumption

520
00:52:28.800 --> 00:52:34.800
Even with the annual consumption, there's enough proven reserves magically keep increasing

521
00:52:34.800 --> 00:52:42.800
And the reason why technologists tend to overlook this, and they did that, the famous flopper rule on this was the famous, was the Global 2000 Report

522
00:52:42.800 --> 00:52:47.800
I think it was submitted to President Carter in the mid-70s

523
00:52:47.800 --> 00:52:53.800
who claimed that by 1980 or 1985 oil would disappear, plus everything else.

524
00:52:53.800 --> 00:52:59.800
They used computer models and big-shot technology. The problem was there wasn't any money economists in the lot.

525
00:52:59.800 --> 00:53:05.800
And they forgot about the price system. But Marx, everybody, is not an economist.

526
00:53:05.800 --> 00:53:09.800
They forget about the price system. They assume that prices are not important.

527
00:53:09.800 --> 00:53:14.800
And so they assume that demand has nothing to do with prices and supply has nothing to do with prices.

528
00:53:14.800 --> 00:53:23.280
And so, what happens in real life is, as I say, when the price of oil goes up, people

529
00:53:23.280 --> 00:53:27.920
start buying less of it, and also they start looking for more of it.

530
00:53:27.920 --> 00:53:30.880
And so the supply keeps increasing.

531
00:53:30.880 --> 00:53:38.920
And this is exactly what happened, and refutes all these doom and doom forecasters, are constantly

532
00:53:38.920 --> 00:53:40.920
being refuted for that reason.

533
00:53:40.920 --> 00:53:52.920
We'll see later on, this is exactly what happened to OPEC. OPEC finally cut its throat. It took some years to do it, but they finally got to the point where non-OPEC countries were finding and producing more oil, like Britain and stuff like that.

534
00:53:52.920 --> 00:54:04.920
At any rate, this is now your arm, you see. You're a technologist who is now armed with economic knowledge, which most technologists don't have.

535
00:54:04.920 --> 00:54:08.920
I'll give you already a leg up. The next guy says the oil is going to disappear in ten years.

536
00:54:08.920 --> 00:54:13.920
Remember, you've heard that they've been saying this for a hundred years now.

537
00:54:22.920 --> 00:54:27.920
There's also, by the way, I'm not going to take any position on this because this is not my area.

538
00:54:27.920 --> 00:54:34.920
I just want to point out to you that there's apparently a maverick, big shot astrophysicist who's also big in geology and everything else,

539
00:54:34.920 --> 00:54:42.480
And now, who claims that oil is not produced from fossil fuels, does not come from vegetable

540
00:54:42.480 --> 00:54:48.000
or animal sediments, but the hydrocarbons really come from other stuff, non-organic

541
00:54:48.000 --> 00:54:49.000
matter.

542
00:54:49.000 --> 00:54:53.400
So if he's proven right, this means there's a lot of oil, particularly natural gas, way

543
00:54:53.400 --> 00:54:54.400
down deep.

544
00:54:54.400 --> 00:54:56.960
And so long probes will find a lot of stuff down there.

545
00:54:56.960 --> 00:55:01.280
If they do, then all the stuff gets shot to hell, because then there's almost no shortage

546
00:55:01.280 --> 00:55:11.000
ever. Especially natural gas. Anyway, Sweden is now having a deep probe, which will apparently

547
00:55:11.000 --> 00:55:20.000
test this theory. So it should come up in a year or two to find out whether this is true

548
00:55:20.000 --> 00:55:27.400
or not. Apparently, meteor, but his basis of thinking, one of the things he says is that

549
00:55:27.400 --> 00:55:51.700
Okay, so we now see how prices are determined by supply and demand, and how in the long run

550
00:55:51.700 --> 00:55:56.900
they're determined by supply and demand, how increases in demand will pull resources

551
00:55:56.900 --> 00:56:02.500
into areas, decreasing demand will take resources away from those areas.

552
00:56:02.500 --> 00:56:07.740
And so that consumer demand is sort of a king and queen of the economic system.

553
00:56:07.740 --> 00:56:12.300
Consumers determine what will be profitable and therefore what will be produced, and what

554
00:56:12.300 --> 00:56:16.740
will make it on the market and what won't.

555
00:56:16.740 --> 00:56:26.180
The famous example, some writers claim that, intellectuals claim that demand is determined

556
00:56:26.180 --> 00:56:29.860
by advertising. All you have to do is advertise something and people will buy it. Advertisers

557
00:56:29.860 --> 00:56:36.140
wish that were true and make their life a lot easier. It not only doesn't always work.

558
00:56:36.140 --> 00:56:39.500
You need advertising in order to sell something, especially a new product, but advertising

559
00:56:39.500 --> 00:56:43.620
is no panacea. It was, of course, the famous example of the etzel, the flop-a-roo of the

560
00:56:43.620 --> 00:56:51.220
etzel car, which had lots of advertising, lots of clapper items, a total flop-a-roo.

561
00:56:51.220 --> 00:56:56.060
Right now the etzel is fairly heavily in demand as a collector's item, by the way. That's

562
00:56:56.060 --> 00:56:59.060
And you get to the point where it's a collector's item.

563
00:56:59.060 --> 00:57:06.060
Another famous flopperoo was originally when shoes were, there's a big thing with shoes that were made out of Corfan instead of leather.

564
00:57:06.060 --> 00:57:10.060
I think Corfan has made a comeback in a sort of a mixed system.

565
00:57:10.060 --> 00:57:15.060
Anyway, the idea was Corfan's shoes were so invasive that the shoe never wears out.

566
00:57:15.060 --> 00:57:19.060
Which is undoubtedly true, except the problem was the feet wore out.

567
00:57:19.060 --> 00:57:22.060
So nobody wanted to wear those damn things.

568
00:57:22.060 --> 00:57:30.880
is again a total flop-a-roo, something slightly forgotten by the technologists who were crazy

569
00:57:30.880 --> 00:57:31.880
about Corfan.

570
00:57:31.880 --> 00:57:38.420
At any rate, so these things, and by the way, one of the examples of how the man is not

571
00:57:38.420 --> 00:57:43.740
determined by advertising is the existence of a huge market research subculture in the

572
00:57:43.740 --> 00:57:48.180
United States, a whole bunch of market researchers, it's also a good part-time occupation by the

573
00:57:48.180 --> 00:58:18.180
for people who want to spend a few hours a week at this thing, and what they do is the businessmen are desperately trying to find out will consumers buy this product, will they buy this ad, will they go for it, and obviously an indication is they can't determine anything, they're just trying to find out, which will they like better, which will they dislike more, they're constantly trying to find out desperately courting the consumer, trying to figure out what the consumer will like or won't like, it's hardly a determined process.

574
00:58:18.180 --> 00:58:36.180
And then one thing about, and sometimes of course intellectuals gripe about the stridently of advertising, of advertising, but you have to realize it's a great world, it's a great system where consumers are courted, even stridently, for trying my product, you have to get the consumer's attention first, the consumer's bombarded by all sorts of stuff.

575
00:58:36.180 --> 00:58:46.180
These people are busy, they've got lots of things to think about or whatever, and so why should they worry about some product, why do you have to sort of catch the attention of the person, hey, here's my product, fantastic.

576
00:58:46.180 --> 00:58:48.620
In socialist countries, they don't worry about consumers.

577
00:58:48.620 --> 00:58:49.940
Consumers are pain in the neck.

578
00:58:49.940 --> 00:58:52.260
There's not much advertising as a result.

579
00:58:52.260 --> 00:58:53.380
There's no courting the consumer.

580
00:58:53.380 --> 00:58:56.220
Consumers are, as I say, are a burden.

581
00:58:56.220 --> 00:58:58.940
It's a much worse system to be a burden,

582
00:58:58.940 --> 00:59:00.420
a consumer to be a burden than to be courted,

583
00:59:00.420 --> 00:59:01.260
I'll tell you that.

584
00:59:03.340 --> 00:59:04.340
In socialist countries,

585
00:59:04.340 --> 00:59:05.660
in countries where government is in the saddle

586
00:59:05.660 --> 00:59:07.260
instead of consumers,

587
00:59:07.260 --> 00:59:09.860
then it's considered,

588
00:59:09.860 --> 00:59:13.340
anytime anybody uses something or consumes something,

589
00:59:13.340 --> 00:59:15.780
you're wasting the social product, quote unquote.

590
00:59:15.780 --> 00:59:21.780
You're a consumer, you're wasting this. The government, the bureaucrats own the thing, and they're reluctant to have anybody use it.

591
00:59:21.780 --> 00:59:26.780
Making it shorter. That's the thinking that goes behind it.

592
00:59:26.780 --> 00:59:32.780
You can see here, we'll get to the water shortage, the alleged water shortage later on, but you can see here when the water shortage hit.

593
00:59:32.780 --> 00:59:37.780
The whole attitude on the part of the, here's the government which essentially municipalized the water industry.

594
00:59:37.780 --> 00:59:44.780
The water industry used to be private way back, and now you have all government water companies, water services.

595
00:59:44.780 --> 00:59:51.780
The whole attitude on the part of these guys is the consumers are a pain in the neck. They're using water. Stop using it. That's their attitude.

596
00:59:51.780 --> 00:59:58.780
Great attitude. Stop using everything. You'll never have any shortage if nobody eats, drinks and does anything else.

597
00:59:58.780 --> 01:00:07.780
So they immediately start blaming the consumers. The water shortage is because consumers are drinking too much, they're showering too much, whatever.

598
01:00:07.780 --> 01:00:13.780
They're washing their cars. And a private enterprise, in a private firm, they don't blame consumers. They're trying to get their custom.

599
01:00:13.780 --> 01:00:18.780
They try to get their custom. They try to get people to use the product. They don't consider it a pain in the neck. They consider it great.

600
01:00:18.780 --> 01:00:22.780
They're trying to find ways to get people to increase the consumption of the product.

601
01:00:22.780 --> 01:00:28.780
They don't blame them. As a matter of fact, if you have a private water company, they try desperately to get more water.

602
01:00:28.780 --> 01:00:37.780
They try to get the water, enough water, try to get the reservoirs and pipes and pipelines and all sorts of stuff in such a way that people can have plenty of water to use.

603
01:00:37.780 --> 01:00:41.420
It's only when government supplies it that the whole thing is a pain in the neck, because

604
01:00:41.420 --> 01:00:44.980
government doesn't live by profit, they don't care about profits, they don't go bankrupt

605
01:00:44.980 --> 01:00:50.620
if they have deficits, they just tax the people more than they get to make up the money.

606
01:00:50.620 --> 01:00:55.780
Uncle Sapp, in other words, the tax payer, pays the difference, so that's a totally

607
01:00:55.780 --> 01:01:00.540
different attitude, plus the different economics, totally different attitude of government officials

608
01:01:00.540 --> 01:01:01.540
in this thing.

609
01:01:01.540 --> 01:01:05.340
There's no incentive for them to supply water, a lot of it, or efficiently or anything else,

610
01:01:05.340 --> 01:01:15.340
The whole thing becomes something to get on the payroll, get your guys, your organization people on the payroll, and also get the taxpayers to keep funneling money into it.

611
01:01:15.340 --> 01:01:25.340
So, you never have a private firm saying, well, stop using New York, it's your fault. You're drinking too much water, you're showering too much. That's not the attitude.

612
01:01:25.340 --> 01:01:27.340
That is the attitude, of course, of the same with government.

613
01:01:27.340 --> 01:01:32.340
We'll get to, when we get to water shortage later on, we'll see how the pricing system has a big effect on that.

614
01:01:32.340 --> 01:01:44.340
But as a general attitude, you can see right away the difference between courting the consumer, trying to get people to buy more of your stuff, considering consumption, or you as just sort of a pain in the neck, necessarily evil at best.

615
01:01:44.340 --> 01:02:08.340
We now have each individual price of each individual good, how each individual price is determined by the intersection of a falling demand curve and a vertical supply line for any given time period

616
01:02:08.340 --> 01:02:21.340
and how it changes over time, either by change in supply curve or change in demand curve, which then becomes a resource pulling effect, in other words, which then increases or decreases resources going into the particular product.

617
01:02:21.340 --> 01:02:27.340
What we now have to look at is the relationship between different goods.

618
01:02:27.340 --> 01:02:35.340
In other words, what we've been doing so far is talking about each good at a time.

619
01:02:35.340 --> 01:02:43.300
And now we have to start talking about what the relationships are between different products.

620
01:02:43.300 --> 01:02:46.020
Some goods are close substitutes.

621
01:02:46.020 --> 01:02:50.460
Every good in a sense is a substitute for a consumer dollar, in which you can spend more

622
01:02:50.460 --> 01:02:51.460
of something.

623
01:02:51.460 --> 01:02:53.500
The money you have is fixed.

624
01:02:53.500 --> 01:02:59.500
If you spend more on good X, you might necessarily be spending less on good Y, that's a general situation

625
01:02:59.500 --> 01:03:04.500
But more than that, you have some goods which are close substitutes

626
01:03:12.500 --> 01:03:14.500
And some goods which are not

627
01:03:14.500 --> 01:03:19.500
And close substitutes have a different relationship between their demand and supply curves

628
01:03:19.500 --> 01:03:22.500
For example, let's get to the coffee case

629
01:03:23.500 --> 01:03:48.500
Coffee. Coffee supply falls because of a big frost, and price goes up. There are substitutes

630
01:03:48.500 --> 01:03:51.420
for coffee, which are going to become intimately related to this thing. In other words, when

631
01:03:51.420 --> 01:03:55.700
When people started buying less coffee because of the increased price, they shifted to other

632
01:03:55.700 --> 01:03:57.300
things like cocoa and tea.

633
01:03:57.300 --> 01:04:08.540
In other words, this is tea, which is a close substitute of coffee, the demand curve for

634
01:04:08.540 --> 01:04:15.460
tea went up in response, in other words, people were willing to buy tea, increased purchase

635
01:04:15.460 --> 01:04:18.860
at any given price because the demand curve went up in response to the higher price for

636
01:04:18.860 --> 01:04:19.860
coffee.

637
01:04:19.860 --> 01:04:48.860
In other words, the chain of cause and effect works like this, an increase, a fall in supply of X, in the words, coffee, raises the price of X, but since X and Y are co-substitutes, an increase in the price of X brings about an increase in demand for Y.

638
01:04:48.860 --> 01:05:18.860
because X is not more expensive, coffee is more expensive, a lot of people say why the heck would coffee, I'm shifting to tea, you're only a marginal coffee drinker, you're going to shift to tea, as you shift to tea, like that, the price of tea begins to go up, how much it goes up we don't know, it all depends on the tea market, the coffee market or whatever, but the point is, there's now an increase in demand curve for tea which leads the price of tea to go up also eventually.

639
01:05:18.860 --> 01:05:41.860
to some extent. So we now have demand for Y increases the price of Y. In other words, in response to the more expensive coffee, demand for T goes up and the price of T becomes also more expensive, or how much it does we don't know. It's not a quantitative law, it's a qualitative law.

640
01:05:41.860 --> 01:05:54.860
So we have a situation where two things are competitive as a drive here toward when the supply changes, as a drive toward making the price of the other one also competitive by this kind of process.

641
01:05:54.860 --> 01:06:04.860
It becomes more expensive, people then turn to tea because it's cheaper, relatively cheaper than coffee now, and tea becomes more expensive eventually too.

642
01:06:04.860 --> 01:06:15.860
So competition then cuts not only within each product, also between close substitutes, the same way for cocoa, the same process occurred for cocoa.

643
01:06:15.860 --> 01:06:32.860
We have a cocoa, we have a man for cocoa going up, man for Z increases the price of Z.

644
01:06:40.860 --> 01:06:43.860
Let's look at the other way around now.

645
01:06:45.860 --> 01:07:12.720
Increased supply of coffee, coffee now crosses over, price goes down, and the fact that coffee

646
01:07:12.720 --> 01:07:17.440
Coffee is now cheaper, the demand curve for tea drops, so the demand curve for tea falls

647
01:07:17.440 --> 01:07:23.640
because coffee is cheaper, people are willing to buy less tea at any given price, and so

648
01:07:23.640 --> 01:07:26.000
the price of tea then drops in response to that.

649
01:07:26.000 --> 01:07:31.480
In other words, you just reverse the signs here, an increase in supply of x will lead

650
01:07:31.480 --> 01:07:37.380
to a fall in the price of x, in which the term will lead to a drop in the demand for

651
01:07:37.380 --> 01:07:49.380
For y, the substitute, and this will lead to a drop in the price of y. Similarly for z, the demand curve for cocoa falls, the price of cocoa falls along with it.

652
01:07:49.380 --> 01:07:56.380
That's the close substitute. This happens all throughout the market, of course, not just for coffee and tea, but for everything.

653
01:07:56.380 --> 01:08:02.380
Substitutes for raw materials, substitutes for machinery, metals, all sorts of things.

654
01:08:02.380 --> 01:08:07.480
Iron, Aluminum, whatever, Aluminum and Magnesium, all these things are substitutes in one way or the other.

655
01:08:07.480 --> 01:08:15.480
They're not perfect substitutes, but they're close substitutes and they affect each other's market, the impact on each other's market.

656
01:08:21.480 --> 01:08:23.480
Let's see what happens when there's a...

657
01:08:26.980 --> 01:08:28.980
That's what happens when there's a change in supply.

658
01:08:28.980 --> 01:08:36.740
Changes in supply will cause a change in the price and a similar change in prices for the

659
01:08:36.740 --> 01:08:37.740
other substitutes.

660
01:08:37.740 --> 01:08:42.660
On the other hand, something different happens when there's a change in demand, because a

661
01:08:42.660 --> 01:08:47.460
change in demand usually reflects a change in the value scale between, say, coffee and

662
01:08:47.460 --> 01:08:48.460
tea anyway.

663
01:08:48.460 --> 01:09:02.580
Let's say this is the coffee market, and this is the tea market, and let's say people begin

664
01:09:02.580 --> 01:09:03.580
to shift from tea to coffee.

665
01:09:03.580 --> 01:09:07.260
As a matter of fact, originally in the United States, we drank mostly tea.

666
01:09:07.260 --> 01:09:10.900
Coffee was sort of the late edition.

667
01:09:10.900 --> 01:09:13.700
So there's a big shift from tea to coffee.

668
01:09:13.700 --> 01:09:22.700
The demand curve for coffee goes up, and eventually supply increases in response to it.

669
01:09:22.700 --> 01:09:29.700
The demand curve for coffee for tea goes down, and the price falls, and eventually the supply will fall in response.

670
01:09:29.700 --> 01:09:36.700
But when you have this kind of a shift, in other words, when you have a shift reflecting changes in the value scales of the consumer,

671
01:09:36.700 --> 01:09:38.700
then there's an opposite change in price.

672
01:09:38.700 --> 01:09:48.700
In other words, the coffee price goes up, at least in the short run to reflect the increased demand for coffee, and the price of tea goes down to reflect the fall in the demand for tea.

673
01:09:48.700 --> 01:09:57.700
So in this case, in the case where the value scales shift, the prices move in opposite directions instead of the same direction, because now you're having a difference in values in the consumer.

674
01:09:57.700 --> 01:10:06.700
They don't want tea anymore, they shift away from it, the price of tea drops in response to that, they want more coffee and the price of coffee goes up in response to that.

675
01:10:06.700 --> 01:10:10.700
Moving in the opposite directions in response to opposite changes in values.

676
01:10:10.700 --> 01:10:14.700
When there was a supply change, then it was a change in the same direction,

677
01:10:14.700 --> 01:10:18.700
because the values remained the same, the value scales remained the same,

678
01:10:18.700 --> 01:10:22.700
just the different supply conditions. Now you have a shift in value scales.

679
01:10:22.700 --> 01:10:26.700
The value scales are all relevant to each other. One thing goes up, the other thing has to go down,

680
01:10:26.700 --> 01:10:30.700
because it's all ranking, if you remember.

681
01:10:30.700 --> 01:10:34.700
So when white wine, red wine, has been an increase

682
01:10:34.700 --> 01:10:42.700
When I compare it to red wine, of course there's a shift in supply, and the price drops in response to that.

683
01:10:42.700 --> 01:10:48.700
So then the changes in price are opposite to each other.

684
01:10:48.700 --> 01:10:52.700
So that's what happens with close substitutes.

685
01:10:52.700 --> 01:10:57.700
Okay, we've got a big dose here tonight, so I think I'll leave at this point.
