It is wrong to assume always that increased spending does not raise the real output but raise prices only. Essentially, as money supply goes up, prices go up, and as the supply goes down, prices will follow as well. For example, an increase in cost of production has an important bearing on the price level. Long Period: The theory is based on the assumption of long period. During underemployment an increase in money supply will tend to raise output level and, hence, T, but not P.
Monetary Theory of Prices: The quantity theory of money upholds the view that the general level of prices is mainly a monetary phenomenon. When the money supply changes, there is a proportional change in price levels, and when price levels change, the money supply changes by the same proportion. This Friedmanian words are enough to establish the essence of quantity theory of money inflation is largely caused by the excessive growth of money supply and by nothing else. This diagram is interesting in the sense that it first establishes the relationship between money supply and national output or national income below the full employment stage Y F. It was first formulated by Irving Fisher in the 1930s. The non-monetary factors, like taxes, prices of imported goods, industrial structure, etc. Another way to understand this theory is to recognize that money is like any other commodity: increases in its supply decrease marginal value the buying capacity of one unit of currency.
Therefore, any change in M triggers an immediate change in P, i. The quantity theory of money states that the quantity of money is the main determinant of the price level or the value of money. It means that in the ex-post or factual sense, the equation must always be true. The consumer, therefore, pays twice as much for the same amount of the good or service. Criticisms of the Theory : The Fisherian quantity theory has been subjected to severe criticisms by economists. T also remains constant and is independent of other factors such as M, M, V and V. A change in money demand or a change in the money supply will yield a change in the value of money and in the price level.
Money as a Store of Value Ignored: The quantity theory of money considers money only as a medium of exchange and completely ignores its importance as a store of value. Everyone is interested in some sectional price level. It ignores the role of demand for money in causing changes in the value of money. Quantity theory of money equation The quantity theory of money is built on an equation created by Irving Fisher 1867-1947 , an American economist, inventor, statistician and progressive social campaigner. A majority of opponents of the theory argue that in the short run prices are sticky, but the theory tends to hold true in the long run, making testing in a long run not necessary as there seems to be a consensus the theory holds true in the long run. It throws no light on the short-run problems. Ludwig von Mises 1881-1973 , a theoretical Austrian School economist, who lectured and wrote extensively on behalf of classical liberalism, said that while the quantity theory of money — at its core — was valid, it should not focus on the money supply without adequately explaining the demand for money.
There always exist inactive balances which exert no pressure on the prices of goods and services. These factors are relatively stable and change very slowly over time. The effect of money on real output, however, is a bit less clear. However, everybody continues hoarding cash and is not willing to take risks. Third, Keynes does not believe that the relationship between the quantity of money and the price level is direct and proportional. Rather, it is an indirect one via the rate of interest and the level of output. The rapid expansion of output in some special situations like emergency or recovery demonstrates that a considerable change in transactions may occur even during a relatively short period.
So, quantity theory of money breaks down when resources remain at full employment. No, the data show many outliers such as Argentina, Nicaragua, and Poland. The Fed has the power to adjust the money supply by increasing or decreasing the number of bills in circulation. This happens because more money is in circulation, so each bill becomes worth less. As inflation rises, the , or the value of money, decreases. In other words, national expenditure, i. Because rising prices give profit incentives to business expansion, a rise in P tends to raise T which may cause an increase in the quantity of money and its velocity of circulation.
After attaining the stage of full employment, an increase in effective demand which is the sum of consumption expenditure, investment expenditure and government expenditure i. Finally, it does not propose any casual relationship between the money supply and the price level, which may be related to each other. Wage will rise less rapidly or relative wages will fall in the labour surplus areas, thereby reducing unemployment Thus, through a judicious use of monetary policy, the time lag between disequilibrium and adjustment can e. If the money supply is controlled, the rest of the economy will look after itself, so say monetarists. Nobody else can make this policy decision.
According to Keynes, an increase in money supply is tantamount to an increase in effective demand. Consequently, the price level may change more in proportion to a change in the quantity of money. Supply of bank money or credit money is influenced largely by the interest rate. Economics News can include stories that are local, national, and international in scale. Instead Friedman argues that when the amount of money increases, the velocity also tends to go up, and vice versa. What we find in reality is unemployment or underemployment of resources.
No Direct and Proportionate Relation between M and P: Keynes criticised the classical quantity theory of money on the ground that there is no direct and proportionate relationship between the quantity of money M and the price level P. On the other hand, price level will rise. If, on the other hand, the average price level is low and goods and services tend to cost little money, consumers will demand less money. Similarly, a change in P may cause a change in M. The equation of exchange is an identity equation, i. Essentially, the theory's assumptions imply that the value of money is determined by the amount of money available in an economy.
