NOTE 5.08. Money Costs, Prices, and Alfred Marshall

1
00:00:00.000 --> 00:00:07.440
8. Money, Costs, Prices, and Alfred Marshall

2
00:00:07.440 --> 00:00:13.800
In the E.R.E., therefore, every good sold to consumers will sell at a certain final

3
00:00:13.800 --> 00:00:21.580
equilibrium price, and at certain total sales. These receipts will accrue, in part, to capitalists

4
00:00:21.580 --> 00:00:28.200
in the form of interest income, and the remainder to owners of land and labor. The payments

5
00:00:28.200 --> 00:00:33.960
Costs of income to the producers have also been popularly termed costs.

6
00:00:33.960 --> 00:00:42.240
These are clearly money costs, or money expenses, and obviously are not the same thing as costs

7
00:00:42.240 --> 00:00:47.480
in the psychic sense of subjective opportunity foregone.

8
00:00:47.480 --> 00:00:52.280
Money costs may be ex post as well as ex ante.

9
00:00:52.280 --> 00:00:58.880
In the ERE, of course, ex ante and ex post calculations are always the same.

10
00:00:58.880 --> 00:01:05.980
However, the two concepts become linked when psychic costs are appraised as much as possible

11
00:01:05.980 --> 00:01:07.840
in monetary terms.

12
00:01:07.840 --> 00:01:15.160
Thus, payment to factors may be 95 ounces and recorded as a cost, while the capitalist

13
00:01:15.160 --> 00:01:22.200
who earns an interest of 5 ounces considers 100 as an opportunity cost.

14
00:01:22.200 --> 00:01:37.040
If for the moment we include as money costs factor payments and interest, then in the

15
00:01:37.040 --> 00:01:45.960
ERE money costs equal total money sales for every firm in every line of production.

16
00:01:45.960 --> 00:01:51.720
Strictly this assumption is incorrect, and we make it in this section only for purposes

17
00:01:51.720 --> 00:01:56.320
Profits of Simplicity For interest may be an opportunity cost for

18
00:01:56.320 --> 00:02:03.920
an individual investor, but it is not a money cost, nor is it an opportunity cost for the

19
00:02:03.920 --> 00:02:06.600
aggregate of capitalists.

20
00:02:06.600 --> 00:02:13.400
A firm earns entrepreneurial profits when its return is more than interest, suffers

21
00:02:13.400 --> 00:02:17.800
entrepreneurial losses when its return is less.

22
00:02:17.800 --> 00:02:25.460
In our production process, consumers will pay 100 ounces, money sales, and money costs

23
00:02:25.460 --> 00:02:33.040
are 100 ounces, factor plus interest income, and there will be similar equality for all

24
00:02:33.040 --> 00:02:35.880
other goods and processes.

25
00:02:35.880 --> 00:02:41.880
What this means in essence is that there are no entrepreneurial profits or losses in the

26
00:02:41.880 --> 00:02:49.200
CERE, because there is no change of data or uncertainty about possible change.

27
00:02:49.200 --> 00:02:56.360
If total money sales equal total money costs, then it evidently follows that total money

28
00:02:56.360 --> 00:03:03.400
sales per unit sold will equal total money costs per unit sold.

29
00:03:03.400 --> 00:03:09.580
This follows from elementary rules of arithmetic, but the money sales per unit are equal to

30
00:03:09.580 --> 00:03:16.420
to the money price of the good, by definition, while we shall call the total money costs

31
00:03:16.420 --> 00:03:20.940
per unit the average money cost of the good.

32
00:03:20.940 --> 00:03:28.220
It likewise follows, therefore, that price will equal average money cost for every good

33
00:03:28.220 --> 00:03:30.940
in the ERE.

34
00:03:30.940 --> 00:03:36.900
Strange as it may seem, a great many writers on economics have deduced from this a curious

35
00:03:36.900 --> 00:03:38.940
conclusion indeed.

36
00:03:38.940 --> 00:03:46.300
They have deduced that in the long run, that is, in the ERE, the fact that costs equals

37
00:03:46.300 --> 00:03:54.220
sales or that cost equals price implies that costs determine price.

38
00:03:54.220 --> 00:04:02.060
The price of the good discussed previously is 100 ounces per unit, allegedly because

39
00:04:02.060 --> 00:04:07.900
the cost, average money cost, is 100 ounces per unit.

40
00:04:07.900 --> 00:04:13.360
This is supposed to be the law of price determination in the long run.

41
00:04:13.360 --> 00:04:18.860
It would seem to be crystal clear, however, that the truth is precisely the reverse.

42
00:04:18.860 --> 00:04:25.580
The price of the final product is determined by the valuations and demands of the consumers,

43
00:04:25.580 --> 00:04:29.900
and this price determines what the cost will be.

44
00:04:29.900 --> 00:04:36.020
If the consumers value the product mentioned so that its price is 50 ounces instead of

45
00:04:36.020 --> 00:04:51.260
In the long run, when the effects of uncertainty are removed, that costs of production, here,

46
00:04:51.260 --> 00:04:56.200
factor payment plus interest payment, will equal the final price.

47
00:04:56.200 --> 00:05:02.620
We have seen above how factor incomes are at the mercy of consumer demand, and fluctuate

48
00:05:02.620 --> 00:05:05.020
according to that demand.

49
00:05:05.020 --> 00:05:10.900
Higher payments are the result of sales to consumers, and do not determine the latter

50
00:05:10.900 --> 00:05:12.980
in advance.

51
00:05:12.980 --> 00:05:19.580
Costs of production, then, are at the mercy of final price, and not the other way around.

52
00:05:19.580 --> 00:05:25.920
It is ironic that it is precisely in the ERE that this causative phenomenon should be the

53
00:05:25.920 --> 00:05:27.180
clearest.

54
00:05:27.180 --> 00:05:34.080
For in the ERE, we see quite evidently that consumers pay and determine the final price

55
00:05:34.080 --> 00:05:40.600
Price of the Product, that it is through these payments and these payments alone that factors

56
00:05:40.600 --> 00:05:46.600
and interest are paid, that therefore the amount of the payments and the total costs

57
00:05:46.600 --> 00:05:52.940
of production are determined by price and not vice versa.

58
00:05:52.940 --> 00:05:57.860
Money costs are the opposite of a basic determining factor.

59
00:05:57.860 --> 00:06:04.340
They are dependent on the price of the product, and on consumer demands.

60
00:06:04.340 --> 00:06:10.180
In the real world of uncertainty, it is more difficult to see this, because factors are

61
00:06:10.180 --> 00:06:17.340
paid in advance of the sale of the product, since the capitalist entrepreneurs speculatively

62
00:06:17.340 --> 00:06:24.260
advance money to the factors in the expectation of being able to recoup their money with a

63
00:06:24.260 --> 00:06:29.560
The Surplus for Interest and Profit After Sale to the Consumers

64
00:06:29.560 --> 00:06:36.100
Whether they do so or not depends on their foresight regarding the state of consumer demand

65
00:06:36.100 --> 00:06:39.520
and the future prices of consumers' goods.

66
00:06:39.520 --> 00:06:45.180
In the real world of immediate market prices, of course, the existence of entrepreneurial

67
00:06:45.180 --> 00:06:54.080
profit and loss will always prevent costs and receipts, cost and price, from being identical,

68
00:06:54.080 --> 00:07:02.660
And it is obvious to all that price is solely determined by valuations of stock, by utilities,

69
00:07:02.660 --> 00:07:05.500
and not at all by money cost.

70
00:07:05.500 --> 00:07:12.580
But although most economists recognize that in the real world, the so-called short run,

71
00:07:12.580 --> 00:07:18.840
costs cannot determine price, they are seduced by the habit of the individual entrepreneur

72
00:07:18.840 --> 00:07:25.920
of Dealing in Terms of Cost as the Determining Factor and they apply this procedure to the

73
00:07:25.920 --> 00:07:33.280
case of the ERE and therefore to the inherent long-run tendencies of the economy.

74
00:07:33.280 --> 00:07:39.360
Their grave error, as will be discussed further below, comes from viewing the economy from

75
00:07:39.360 --> 00:07:45.960
the standpoint of an individual entrepreneur rather than from that of an economist.

76
00:07:45.960 --> 00:07:53.400
To the individual entrepreneur, the cost of factors is largely determined by forces outside

77
00:07:53.400 --> 00:07:56.600
himself and his own sales.

78
00:07:56.600 --> 00:08:03.400
The economist, however, must see how money costs are determined, and, taking account

79
00:08:03.400 --> 00:08:09.180
of all the interrelations in the economy, must recognize that they are determined by

80
00:08:09.180 --> 00:08:16.100
by Final Prices Reflecting Consumer Demands and Valuations

81
00:08:16.100 --> 00:08:21.840
The source of the error will become clearer when we consider a world of non-specific as

82
00:08:21.840 --> 00:08:24.460
well as specific factors.

83
00:08:24.460 --> 00:08:30.620
However, the essentials of our analysis and its conclusion remain the same in that more

84
00:08:30.620 --> 00:08:34.100
complex and realistic case.

85
00:08:34.100 --> 00:08:40.480
The classical economists were under the delusion that the price of the final product is determined

86
00:08:40.480 --> 00:08:47.860
by costs of production, or rather, they fluctuated between this doctrine and the labor theory

87
00:08:47.860 --> 00:08:54.540
of value, which isolated the money costs of labor and picked that segment of the cost

88
00:08:54.540 --> 00:08:58.100
of production as the determinant of price.

89
00:08:58.100 --> 00:09:03.500
They slurred over the determination of the prices of such goods as old paintings that

90
00:09:03.500 --> 00:09:07.740
already existed and needed no further production.

91
00:09:07.740 --> 00:09:14.840
The correct relation between prices and costs, as outlined earlier, was developed along with

92
00:09:14.840 --> 00:09:21.140
other outstanding contributions to economics by the Austrian economists, including the

93
00:09:21.140 --> 00:09:28.020
Austrians Carl Menger, Eugen von Boehm-Bawerk and Friedrich von Wieser, and the Englishman

94
00:09:28.020 --> 00:09:30.460
W. Stanley Jevons.

95
00:09:30.460 --> 00:09:37.300
It was with the writings of the Austrian School in the 1870s and 1880s that economics was

96
00:09:37.300 --> 00:09:40.900
truly established as a science.

97
00:09:40.900 --> 00:09:47.060
The very interesting researches by Emil Kauder indicate that the essentials of the Austrian

98
00:09:47.060 --> 00:09:53.940
marginal utility theory, the basis of the view that price determines cost and not vice

99
00:09:53.940 --> 00:10:00.220
and vice versa or mutually had already been formulated by French and Italian economists

100
00:10:00.220 --> 00:10:06.920
of the 17th and 18th centuries, and that the English classical school shunted economics

101
00:10:06.920 --> 00:10:14.700
onto a very wrong road, a road from which economics was extricated only by the Austrians.

102
00:10:14.700 --> 00:10:21.260
Unfortunately, in the science of economics, retrogression in knowledge has taken place

103
00:10:21.260 --> 00:10:24.220
is almost as often as progression.

104
00:10:24.220 --> 00:10:30.880
The enormous advance provided by the Austrian School, on this point as on others, was blocked

105
00:10:30.880 --> 00:10:37.340
and reversed by the influence of Alfred Marshall, who attempted to rehabilitate the classicists

106
00:10:37.340 --> 00:10:43.340
and integrate them with the Austrians, while disparaging the contributions of the latter.

107
00:10:43.340 --> 00:10:48.540
It was unfortunately the Marshallian and not the Austrian approach that exerted the most

108
00:10:48.540 --> 00:10:51.040
influence over later writers.

109
00:10:51.040 --> 00:10:56.540
This influence is partly responsible for the current myth among economists that the Austrian

110
00:10:56.540 --> 00:11:02.780
School is effectively dead and has no more to contribute and that everything of lasting

111
00:11:02.780 --> 00:11:08.240
worth that it had to offer was effectively stated and integrated in Alfred Marshall's

112
00:11:08.240 --> 00:11:10.400
principles.

113
00:11:10.400 --> 00:11:16.580
Marshall tried to rehabilitate the cost of production theory of the classicists by conceding

114
00:11:16.580 --> 00:11:38.900
According to Marshall, both utility and money costs determine price, like blades of a scissors,

115
00:11:38.900 --> 00:11:44.240
but one blade is more important in the short run and another in the long run.

116
00:11:44.240 --> 00:11:49.920
He concludes that, as a general rule, the shorter the period we are considering, the

117
00:11:49.920 --> 00:11:55.080
greater must be the share of our attention which is given to the influence of demand

118
00:11:55.080 --> 00:12:01.000
on value, and the longer the period, the more important will be the influence of cost of

119
00:12:01.000 --> 00:12:03.200
production on value.

120
00:12:03.200 --> 00:12:10.480
The actual value at any time, the market value as it is often called, is often more influenced

121
00:12:10.480 --> 00:12:17.440
by passing events and by causes whose action is fitful and short-lived than by those which

122
00:12:17.440 --> 00:12:19.280
work persistently.

123
00:12:19.280 --> 00:12:25.480
But in long periods these fitful and irregular causes in large measure efface one another's

124
00:12:25.480 --> 00:12:32.480
influence so that in the long run persistent causes dominate value completely.

125
00:12:32.480 --> 00:12:35.020
The implication is quite clear.

126
00:12:35.020 --> 00:12:41.440
If one deals with short-run market values, one is being quite superficial and dwelling

127
00:12:41.440 --> 00:12:46.620
only on fitful and transient causes, so much for the Austrians.

128
00:12:46.620 --> 00:12:52.480
But if one wants to deal with the really basic matters, the really lasting and permanent

129
00:12:52.480 --> 00:13:00.260
causes of prices, he must concentrate on costs of production, pace the classicists.

130
00:13:00.260 --> 00:13:07.060
This impression of the Austrians, their alleged neglect of the long period and one-sided neglect

131
00:13:07.060 --> 00:13:12.500
of costs, has been stamped on economics ever since.

132
00:13:12.500 --> 00:13:18.220
Marshall's analysis suffers from a grave methodological defect, indeed from an almost

133
00:13:18.220 --> 00:13:24.420
hopeless methodological confusion as regards the short run and the long run.

134
00:13:24.420 --> 00:13:31.780
He considers the long run as actually existing, as being the permanent, persistent, observable

135
00:13:31.780 --> 00:13:38.260
element beneath the fitful, basically unimportant flux of market value.

136
00:13:38.260 --> 00:13:46.580
He admits on page 350 that even the most persistent causes are, however, liable to change.

137
00:13:46.580 --> 00:13:52.700
But he clearly indicates that they are far less likely to change than the fitful market

138
00:13:52.700 --> 00:13:53.700
values.

139
00:13:53.700 --> 00:13:57.620
When indeed lies their long-run nature.

140
00:13:57.620 --> 00:14:04.700
He regards the long-run data then as underlying the transient market values in a way similar

141
00:14:04.700 --> 00:14:11.200
to that in which the basic sea level underlies the changing waves and tides.

142
00:14:11.200 --> 00:14:17.520
This analogy, though not used in this context, was often used by classical economists as

143
00:14:17.520 --> 00:14:24.280
has applied to prices and the price level, an application equally erroneous.

144
00:14:24.280 --> 00:14:29.840
For Marshall, then, the long-run data are something that can be spotted and marked by

145
00:14:29.840 --> 00:14:31.200
an observer.

146
00:14:31.200 --> 00:14:37.300
Indeed, since they change far more slowly than the market values, they can be observed

147
00:14:37.300 --> 00:14:39.800
more accurately.

148
00:14:39.800 --> 00:14:44.880
Marshall's conception of the long run is completely fallacious, and this eliminates

149
00:14:44.880 --> 00:14:48.480
It's the whole groundwork of his theoretical structure.

150
00:14:48.480 --> 00:14:55.320
The long-run, by its very nature, never does and never can exist.

151
00:14:55.320 --> 00:15:01.540
This does not mean that long-run, or ERE, analysis is not important.

152
00:15:01.540 --> 00:15:09.240
On the contrary, only through the concept of the ERE can we subject to catallactic analysis,

153
00:15:09.240 --> 00:15:35.240
The ERE is the goal, albeit shifting in the concrete sense, toward which the market moves, but the point at issue is that it is not observable or real, as are actual market prices.

154
00:15:35.240 --> 00:15:40.560
We have seen the characteristics of the evenly rotating economy.

155
00:15:40.560 --> 00:15:47.740
The ERE is the condition that comes into being and continues to obtain when the present existing

156
00:15:47.740 --> 00:15:54.280
market data – valuations, technology, resources – remain constant.

157
00:15:54.280 --> 00:16:00.740
It is a theoretical construct of the economist that enables him to point out in what directions

158
00:16:00.740 --> 00:16:08.000
As the economy tends to be moving at any given time, it also enables the economist to isolate

159
00:16:08.000 --> 00:16:13.120
various elements in his analysis of the economy of the real world.

160
00:16:13.120 --> 00:16:19.560
To analyze the determining forces in a world of change, he must construct hypothetically

161
00:16:19.560 --> 00:16:22.180
a world of non-change.

162
00:16:22.180 --> 00:16:29.340
This is far different from, indeed, it is the reverse of, saying that the long run exists

163
00:16:29.340 --> 00:16:35.940
or that it is somehow more permanently or more persistently existent than the actual

164
00:16:35.940 --> 00:16:37.660
market data.

165
00:16:37.660 --> 00:16:44.740
The actual market prices, on the contrary, are the only ones that ever exist, and they

166
00:16:44.740 --> 00:16:52.940
are the resultants of actual market data, consumer demands, resources, etc., that themselves

167
00:16:52.940 --> 00:16:55.060
change continually.

168
00:16:55.060 --> 00:16:58.460
The long run is not more stable.

169
00:16:58.460 --> 00:17:03.420
This data necessarily change along with the data on the market.

170
00:17:03.420 --> 00:17:11.060
The fact that costs equal prices in the long run does not mean that costs will actually

171
00:17:11.060 --> 00:17:19.140
equal prices, but that the tendency exists, a tendency that is continually being disrupted

172
00:17:19.140 --> 00:17:26.460
in reality by the very fitful changes in market data that Marshall points out.

173
00:17:26.460 --> 00:17:32.540
Paul is here committing the famous fallacy of conceptual realism in which theoretical

174
00:17:32.540 --> 00:17:38.180
constructs are mistaken for actually existing entities.

175
00:17:38.180 --> 00:17:45.940
In sum, rather than being in some sense more persistent and more real than the actual market,

176
00:17:45.940 --> 00:17:53.800
the long run of the ERE is not real at all, but a very useful theoretical construct that

177
00:17:53.800 --> 00:17:59.240
That enables the economist to point out the direction in which the market is moving at

178
00:17:59.240 --> 00:18:07.240
any given time, specifically toward the elimination of profits and losses if existing market data

179
00:18:07.240 --> 00:18:08.960
remain the same.

180
00:18:08.960 --> 00:18:16.640
Thus, the ERE concept is especially helpful in the analysis of profits and losses as compared

181
00:18:16.640 --> 00:18:23.060
to interest, but the market data are the only actual reality.

182
00:18:23.060 --> 00:18:29.580
This is not to deny, and the Austrians never did deny, that subjective costs, in the sense

183
00:18:29.580 --> 00:18:37.100
of opportunity costs and utilities foregone, are important in the analysis of production.

184
00:18:37.100 --> 00:18:43.540
In particular, the disutilities of labor and of waiting, as expressed in the time preference

185
00:18:43.540 --> 00:18:49.820
ratios, determine how much of people's energies and how much of their savings will go into

186
00:18:49.820 --> 00:18:52.000
the production process.

187
00:18:52.000 --> 00:18:57.920
This in the broadest sense will determine or help to determine the total supply of all

188
00:18:57.920 --> 00:19:00.700
goods that will be produced.

189
00:19:00.700 --> 00:19:07.880
But these costs are themselves subjective utilities, so that both blades of the scissors

190
00:19:07.880 --> 00:19:12.360
are governed by the subjective utility of individuals.

191
00:19:12.360 --> 00:19:17.920
This is a monistic and not a dualistic causal explanation.

192
00:19:17.920 --> 00:19:23.960
The costs, furthermore, have no direct influence on the relative amount of the stock of each

193
00:19:23.960 --> 00:19:27.040
good to be produced.

194
00:19:27.040 --> 00:19:31.320
Consumers will evaluate the various stocks of goods available.

195
00:19:31.320 --> 00:19:37.360
How much productive energy and savings will go into producing stock of one particular

196
00:19:37.360 --> 00:19:41.120
good and how much into producing another?

197
00:19:41.120 --> 00:19:47.720
In other words, the relative stocks of each product will depend in turn on entrepreneurial

198
00:19:47.720 --> 00:19:52.720
Marshall's Treatment of the Greatest Monetary Profit

199
00:20:17.720 --> 00:20:22.560
Development of subjective costs was also highly fallacious.

200
00:20:22.560 --> 00:20:28.680
Instead of the idea of opportunity costs, he had the notion that they were real costs

201
00:20:28.680 --> 00:20:32.920
that could be added in terms of measurable units.

202
00:20:32.920 --> 00:20:39.520
Money costs of production then became the necessary supply prices that entrepreneurs

203
00:20:39.520 --> 00:20:46.740
had to pay in order to call forth an adequate supply of the efforts and weightings to produce

204
00:20:46.740 --> 00:20:49.140
a Supply of the Product.

205
00:20:49.140 --> 00:20:55.740
These real costs were then supposed to be the fundamental persisting element that backstops

206
00:20:55.740 --> 00:21:03.300
money costs of production and allowed Marshall to talk of the more persisting, long-run,

207
00:21:03.300 --> 00:21:06.140
normal situation.

208
00:21:06.140 --> 00:21:12.140
Marshall's great error here, and it has permeated the works of his followers and of present-day

209
00:21:12.140 --> 00:21:29.140
is to regard costs and production exclusively from the point of view of an isolated individual entrepreneur or an isolated individual industry rather than viewing the whole economy in all its interrelations.

210
00:21:29.140 --> 00:21:35.820
We must hasten to point out that this is by no means the same criticism as the Neo-Keynesian

211
00:21:35.820 --> 00:21:43.180
charge that economists must deal in broad aggregates and not with individual cases.

212
00:21:43.180 --> 00:21:49.800
The latter approach is even worse, since it begins with holes that have no basis in reality

213
00:21:49.800 --> 00:21:51.140
whatever.

214
00:21:51.140 --> 00:21:57.220
What we are advocating is a theory that deals with all the individuals as they interact

215
00:21:57.220 --> 00:22:04.240
in the Economy, Furthermore, this is the Austrian and not the Walrassian approach, which has

216
00:22:04.240 --> 00:22:06.460
recently come into favor.

217
00:22:06.460 --> 00:22:13.360
The latter deals with interrelations of individuals, the general equilibrium approach, but only

218
00:22:13.360 --> 00:22:20.940
in the ERE, and with mathematical abstractions in the ERE.

219
00:22:20.940 --> 00:22:27.420
Paul is dealing of necessity with particular prices of different goods, and he is attempting

220
00:22:27.420 --> 00:22:34.100
to show that alleged costs of production determine these prices in the long run.

221
00:22:34.100 --> 00:22:42.080
But it is completely erroneous to tie up particular goods with labor versus leisure and with consuming

222
00:22:42.080 --> 00:22:49.260
versus waiting costs, for the latter are only general phenomena, applying and diffusing

223
00:22:49.260 --> 00:22:52.740
Banking Throughout the Entire Economic System.

224
00:22:52.740 --> 00:22:59.660
The price necessary to call forth a non-specific factor is the highest price this factor can

225
00:22:59.660 --> 00:23:03.640
earn elsewhere, an opportunity cost.

226
00:23:03.640 --> 00:23:08.860
What it can attain elsewhere is basically determined by the state of consumer demand

227
00:23:08.860 --> 00:23:10.280
elsewhere.

228
00:23:10.280 --> 00:23:17.460
The foregone leisure and consumption costs in general only help to determine the size,

229
00:23:17.460 --> 00:23:23.460
The general stock of labor and savings that will be applied to production.

230
00:23:23.460 --> 00:23:25.460
All this will be treated further.
