When this assumption holds good, there exists a proportional link between the changes in money supply and the changes in prices.

To begin with, when the quantity of money is M, the price level is P. When the quantity of … When these two assumptions are made the Equation of Exchange becomes the Quantity Theory of Money which shows that there is an exact, proportional relationship between money supply and the price level. M stand for money supply, V is the velocity of money or the average frequency of transactions and the sum is the price and quantity of the good indexed by i but normally we will find it as:. One of the main weaknesses of Fisher’s quantity theory of money is that it neglects the role of the rate of interest as one of the causative factors between money and prices. If these two assumptions hold true, then there is a strictly proportional link between changes in the money supply and changes in prices.

(A) and (B). The quantity theory of money states that the value of money is based on the amount of money in the economy. If these two assumptions hold true, then there is a strictly proportional link between changes in the money supply and changes in prices.

The quantity theory of money implies that a number of interactions are not possible. The assumptions of the simple quantity theory of money are that velocity and output are constant. This reformulated quantity theory of money is illustrated in Figure 67.1 (A) and (B) where OTC is the output curve relating to the quantity of money and PRC is the price curve relating to the quantity of money. 7.

Panel A of the figure shows that as the quantity of money increases from О to M, the level of output also rises along the ОТ portion of the OTC curve. The quantity theory of money is based directly on the changes brought about by an increase in the money supply. In actual life the price level and volume of production move up and down in a cyclical pattern.

Changes in velocity are so small that for all practical purposes velocity can be assumed to be constant over long periods of time, thus resulting in a vertical AS curve.

For a better understanding and appreciation of Friedman’s modern quantity theory, it is necessary to state the major assumptions and beliefs of Friedman. Assumptions of the Quantity Theory. One of the assumptions of the simple quantity theory of money is that output is fixed in the long run, which means the AS curve is vertical at all levels of Real GDP. This article provides an overview and analysis of one of the first macroeconomic theories on record, the Quantity Theory of Money (QTM). In his restatement he says that “money does matter”. The quantity theory of money is both a simple and complex topic. Fisher’s equation of exchange is related to an equilibrium situation in which rate of interest is independent of the quantity of money. The quantity theory is a simple way to explaining why changes in money can disturb the rest of the economy. In doing so I shall briefly outline three strands of quantity theory to emerge from this process and I shall point out their different emphases and focal points.

First, the quantity theory assumes that changes in spending do not simply cause proportional changes in the money stock. Sometimes, the theory is presented by splitting up average quantity of money (M) into two components, namely currency (M1) and banks money (M2) and their respective velocities, V1 and V2.

The assumptions of the simple quantity theory of money are that velocity and output are constant. Chapter 6 The Quantity Theory of Money Frank Hayes In this essay I wish to consider the quantity theory analysis and to extend this into a discussion of the major policy approaches to economic stabilization. Unrealistic Assumptions: This modifies the equation to . However, it is a theory with a number of weaknesses, and it has always had critics who have questioned the assumptions on which it is based. In the short rim these principles of the Quantity Theory are not in accord with facts. Given the assumptions of the theory, MV= PT is an identity. Fisher’s quantity theory of money is explained with the help of Figure 1. In other words, the level of prices in the economy is directly proportional to the quantity of money …

M1V1 + M2V2 = PT.

It is changes in money stock that are the cause, not the effect.

The quantity theory of money assumes that the velocity and output remains constant.
