Fisher did accept that given a rise in the money supply, other changes taking place simultaneously might affect V or T and thus break the proportional relationship between changes in M and changes in P. However, the impact of M by itself on P. holding everything else constant is strictly proportional. This relationship is expressed by the curve P = f (M) from the origin at 45°. TOS 7. The pure quantity theory of money as given by David Hume no doubt established functional relationship between P and M, it did not, however, mean that changes in P were proportional to changes in M. In Hume’s version it was realized that in a dynamic society with growing population and improving technology, output has a tendency to increase and so also the velocity of money. First, the quantity theory of money is unrealistic because it analyses the relation between M and P in the long run. Many Keynesian economists remain critical of the basic tenets of the quantity theory of money and monetarism, and challenge the assertion that economic policies that attempt to influence the money supply are the best way to address economic growth. According to Fisher, PT is SPQ. Given the assumptions of the theory, MV= PT is an identity. As a way of adjusting for this decrease in money's marginal value, the prices of goods and services rises; this results in a higher inflation level. After joining the points P, A, B and M we get a curve PM, which shows the relationship between changes in M and P. The Quantity Theory takes money just like any other commodity, whose value is determined by its demand and supply. As inflation rises, purchasing power decreases. Don Patinkin has critcised Fisher for failure to make use of the real balance effect, that is, the real value of cash balances. Panel A of the figure shows the effect of changes in the quantity of money on the price level. This equation equates the demand for money (PT) to supply of money (MV=M’V). Monetary economics is a branch of economics that studies different theories of money. At the time, Keynes advocated for a government response to the global depression that would involve the government increasing their spending and lowering their taxes in order to stimulate demand and pull the global economy out of the depression. It is, therefore, not applicable to a modern dynamic economy. One of the primary research areas for this branch of economics is the quantity theory of money. In panel В of the figure, the inverse relation between the quantity of money and the value of money is depicted where the value of money is taken on the vertical axis. First, it cannot explain ’why’ there are fluctuations in the price level in the short run. When the purchasing power of a unit of currency decreases, it requires more units of currency to buy the same quantity of goods or services. According to not-so- strict or broad version of the quantity theory of money, there is no doubt that price level changes as a result of changes in the quantity of money, but this change is not direct and proportionate. Price is changed or affected by other factors in the equation but does not affect or cause changes in those factors. The quantity theorists ignored the velocity of money because they were concerned with what Keynes calls transaction and precautionary motives for holding money.

The truth of this proposition is evident from the fact that if M and M’ are doubled, while V, V and T remain constant, P is also doubled, but the value of money (1/P) is reduced to half. Throughout the 1970s and 1980s, the quantity theory of money became more relevant as a result of the rise of monetarism. Prof. Robertson says, “Given the conditions of demand for money, the reaction between its value and the quantity of it available is of this peculiar kind, the larger the number of units available, the smaller in exactly the same proportion, is the value of each unit.” However, the latest version of the old classical quantity theory of money is given by an American Economist. 8. Read this article to learn about the quantity theory of money and its assumptions. One implication of these assumptions is that the value of money is determined by the amount of money available in an economy. Thus the theory is one-sided. As long as we hold money for these purposes, the amount of money held may remain stable but, as soon as we introduce the speculative motive for holding money, we have to admit the possibility of a change in the velocity of money. According to Hume, price level is regarded as a function of the quantity of money [P = f (m)]. Monetary policy refers to the actions undertaken by a nation's central bank to control money supply and achieve sustainable economic growth. 3. 10 per quintal, i.e., with the doubling of the quantity of money (from Rs. The proportion of M’ to M remains constant. According to Keynes, “So long as there is unemployment, output and employment will change in the same proportion as the quantity of money, and when there is full employment, prices will change in the same proportion as the quantity of money.” Thus Keynes integrated the theory of output with value theory and monetary theory and criticised Fisher for dividing economics “into two compartments with no doors and windows between the theory of value and theory of money and prices.”. 2 other things remaining unchanged, the price of wheat will be Rs. Hence, T remains constant. This inverse relationship between the quantity of money and the value of money is shown by downward sloping curve 1/P = f (M). In short, Fisher’s quantity theory does not claim that V or V’ never change, as many critics have claimed. Copyright 10. Disclaimer 9. Conversely, when M decreases from OM1 to OM2 price level also decreases from OP1 to OP3. Fisher’s quantity theory of money is explained with the help of Figure 65.1. In monetary economics, the chief method of achieving economic stability is through controlling the supply of money. Bodin believed that the main cause of the rise in price was an increase in the quantity of money— gold and silver. In the 1930s, Keynes also challenged the quantity theory of money, saying that increases in the money supply actually lead to a decrease in the velocity of circulation and that real income–the flow of money to the factors of production–increased.
