NOTE 11.07. Gains and Losses During a Change in the Money Relation

1
00:00:00.000 --> 00:00:06.000
7. Gains and losses during a change in the money relation.

2
00:00:06.000 --> 00:00:19.000
A change in the money relation necessarily involves gains and losses, because money is not neutral, and price changes do not take place simultaneously.

3
00:00:19.000 --> 00:00:43.000
Let us assume, and this will rarely hold in practice, that the final equilibrium position resulting from a change in the money relation is the same in all respects, including relative prices, individual values, etc., as the previous equilibrium, except for the change in the purchasing power of money.

4
00:00:43.000 --> 00:00:49.800
Actually, as we shall see, there will almost undoubtedly be many changes in these factors

5
00:00:49.800 --> 00:00:56.240
in the new equilibrium situation, but even if there are not, the movement of prices from

6
00:00:56.240 --> 00:01:04.100
one equilibrium position to the next will not take place smoothly and simultaneously.

7
00:01:04.100 --> 00:01:11.160
It will not take place, according to the famous example of David Hume and John Stuart Mill,

8
00:01:11.160 --> 00:01:16.060
Where Everyone Awakens to Find His Money Supply Doubled Overnight

9
00:01:16.060 --> 00:01:23.800
Changes in the demand for money or the stock of money occur in step-by-step fashion, first

10
00:01:23.800 --> 00:01:29.640
having their effect in one area of the economy and then in the next.

11
00:01:29.640 --> 00:01:35.720
Because the market is a complex interacting network, and because some people react more

12
00:01:35.720 --> 00:01:41.700
for Quickly Than Others, movements of prices will differ in the speed of reaction to the

13
00:01:41.700 --> 00:01:44.400
changed situation.

14
00:01:44.400 --> 00:01:49.480
As we have intimated, the following law can be enunciated.

15
00:01:49.480 --> 00:01:55.860
When a change in the money relation causes prices to rise, the man whose selling price

16
00:01:55.860 --> 00:02:04.880
rises before his buying prices gains, and the man whose buying prices rise first loses.

17
00:02:04.880 --> 00:02:11.080
The one who gains the most from the transition period is the one whose selling price rises

18
00:02:11.080 --> 00:02:14.720
first and buying prices last.

19
00:02:14.720 --> 00:02:21.760
Conversely, when prices fall, the man whose buying prices fall before his selling price

20
00:02:21.760 --> 00:02:29.420
gains, and the man whose selling price falls before his buying prices loses.

21
00:02:29.420 --> 00:02:34.520
It should be evident in the first place that there is nothing about rising prices that

22
00:02:34.520 --> 00:02:39.800
that causes gains, or about falling prices that causes losses.

23
00:02:39.800 --> 00:02:45.960
In either situation, some people gain and some people lose from the change, the gainers

24
00:02:45.960 --> 00:02:51.900
being the ones with the greatest and lengthiest positive differential between their selling

25
00:02:51.900 --> 00:02:58.080
and their buying prices, and the losers the ones with the greatest and longest negative

26
00:02:58.080 --> 00:03:00.800
differential in these movements.

27
00:03:00.800 --> 00:03:07.900
Which people gain and which lose from any given change is an empirical question, dependent

28
00:03:07.900 --> 00:03:14.320
on the location of changes in elements of the money relation, institutional conditions,

29
00:03:14.320 --> 00:03:19.000
anticipations, speeds of reaction, etc.

30
00:03:19.000 --> 00:03:24.760
Let us consider the gains and losses from an increase in money stock.

31
00:03:24.760 --> 00:03:29.260
Suppose that we start from a position of monetary equilibrium.

32
00:03:29.260 --> 00:03:36.620
Every person's money relation is in equilibrium, with his stock of and demand for money being

33
00:03:36.620 --> 00:03:37.620
equal.

34
00:03:37.620 --> 00:03:42.660
Now suppose that Mr. Jones finds some new gold, never known before.

35
00:03:42.660 --> 00:03:46.580
A change in Jones' data has taken place.

36
00:03:46.580 --> 00:03:53.100
He now has an excess stock of gold in his cash balance compared with his demand for

37
00:03:53.100 --> 00:03:54.100
it.

38
00:03:54.100 --> 00:03:58.100
Jones acts to spend his excess cash balance.

39
00:03:58.100 --> 00:04:03.280
This new money is spent, let us say, on the products of Smith.

40
00:04:03.280 --> 00:04:09.840
Smith now finds that his cash balance exceeds his demand for money, and he spends his excess

41
00:04:09.840 --> 00:04:13.320
on the products of someone else.

42
00:04:13.320 --> 00:04:20.180
Jones increased supply also increases Smith's selling price and income.

43
00:04:20.180 --> 00:04:24.800
Smith's selling price has increased before his buying price.

44
00:04:24.800 --> 00:04:31.040
He spends the money on the products of Robinson, thus raising the latter's selling prices

45
00:04:31.040 --> 00:04:34.520
while most buying prices have not risen.

46
00:04:34.520 --> 00:04:42.120
As the money is transferred from hand to hand, buying prices rise more and more.

47
00:04:42.120 --> 00:04:49.160
Robinson's selling price increases, for example, but already one of the products he buys, Smith's,

48
00:04:49.160 --> 00:04:50.680
has gone up.

49
00:04:50.680 --> 00:04:55.880
As the process continues, more and more buying prices rise.

50
00:04:55.880 --> 00:05:01.960
The individuals who are far down on the list to receive the new money, therefore, find

51
00:05:01.960 --> 00:05:08.600
that their buying prices have increased while their selling prices have not yet done so.

52
00:05:08.600 --> 00:05:15.000
Of course, the changes in the money supply and in prices may well be insignificant.

53
00:05:15.000 --> 00:05:21.560
But this process occurs however large or small the change in the money stock.

54
00:05:21.560 --> 00:05:28.200
Obviously, the larger the increase in money stock, the greater Ceteris Paribus will be

55
00:05:28.200 --> 00:05:31.260
its impact on prices.

56
00:05:31.260 --> 00:05:38.020
We have seen that an increase in the stock of money leads to a fall in the PPM, and a

57
00:05:38.020 --> 00:05:43.000
decrease in the stock of money leads to a rise in the PPM.

58
00:05:43.000 --> 00:05:55.000
However, there is no simple and uneventful rise and fall in the PPM, for a change in the stock of money is not automatically simultaneous.

59
00:05:55.000 --> 00:06:04.000
New money enters the system at some specific point and then becomes diffused in this way throughout the economy.

60
00:06:04.000 --> 00:06:11.000
The individuals who receive the new money first are the greatest gainers from the increased money.

61
00:06:11.000 --> 00:06:20.000
Those who receive it last are the greatest losers, since all their buying prices have increased before their selling prices.

62
00:06:20.000 --> 00:06:32.000
Monetarily, it is clear that the gains of the approximate first half of the recipients of new money are exactly counterbalanced by the losses of the second half.

63
00:06:32.000 --> 00:06:52.000
Conversely, if money should somehow disappear from the system, say through wear and tear or through being misplaced, the initial loser cuts his spending and suffers most, while the last who feel the impact of a decreased money supply gain the most.

64
00:06:52.000 --> 00:07:10.000
For a decrease in the money supply results in losses for the first owners, who suffer a cut in selling price before their buying prices are lowered, and gains for the last, who see their buying prices fall before their income is cut.

65
00:07:10.000 --> 00:07:17.320
This analysis bears out our assertion that there is no social utility in an increased

66
00:07:17.320 --> 00:07:24.140
supply, nor any social disutility in a decreased supply of money.

67
00:07:24.140 --> 00:07:27.740
This is true for the transition period as well.

68
00:07:27.740 --> 00:07:34.700
An increase in gold is socially useful, that is, beneficial to some without demonstrably

69
00:07:34.700 --> 00:07:52.580
If, as we have been assuming, relative prices and valuations remain the same for all throughout,

70
00:07:52.580 --> 00:07:59.620
the new equilibrium will be identical with the old, except for an all-round price change.

71
00:07:59.620 --> 00:08:05.620
In that case, the gains and losses will be temporary, disappearing upon the advent of

72
00:08:05.620 --> 00:08:07.140
the new equilibrium.

73
00:08:07.140 --> 00:08:11.620
Actually, however, this will almost never occur.

74
00:08:11.620 --> 00:08:17.940
For even if people's values remain frozen, the shift in relative money income during

75
00:08:17.940 --> 00:08:22.700
the transition itself changes the structure of demand.

76
00:08:22.700 --> 00:08:28.280
The gainers of wealth during the transition period will have a structure of preferences

77
00:08:28.280 --> 00:08:30.280
The Theory of Money and Credit

78
00:08:58.280 --> 00:09:21.280
Money changes have this driving force, it may be noted, even in the fanciful case of the automatic overnight doubling of the supply of everyone's cash balance.

79
00:09:21.280 --> 00:09:30.580
For the fact that everyone's money stock doubles does not at all mean that all prices will automatically double.

80
00:09:30.580 --> 00:09:40.680
Each individual has a differently shaped demand-for-money schedule, and it is impossible to predict how each will be shaped.

81
00:09:40.680 --> 00:09:49.480
Some will spend proportionately more of their new money, and others will keep proportionately more in their cash balance.

82
00:09:49.480 --> 00:09:57.980
Many people will tend to spend their new cash balances on different goods from those they had bought with their old money.

83
00:09:57.980 --> 00:10:07.480
As a result, the structure of demand will change, and a decreased PPM will not double all prices.

84
00:10:07.480 --> 00:10:12.480
Some will increase by more, and some by less than double.
