Criticism of Purchasing Power Parity Theory: The purchasing power parity theory has been subject to the following criticisms: The actual rates of exchange Criticisms of absolute price parity fall neatly on to two categories: PPP theory emphasizes the role of prices in exchange rate determination; yet incomes are so Some critics, however, use a reductio ad absurdum to destroy the theory: Of course, under perfect competition, free trade without tariffs, quotas, or exchange 267).

Which of the following is true of the theory of purchasing power parity (PPP)? a. It suggests that in the long run, exchange rates should move toward levels that would equalize the prices of an identical basket of goods in any two countries. The traditional exchange rate models seek for the identification of an equilibrium between two economies in order to calculate the fair value of the exchange rate. An equilibrium based on the relative valuation of an identical commodity, on relative inflation, on the relative level of real interest rates, etc. In this article we will discuss about the Emmanuel’s unequal exchange theory of exchange theory. Marxists like Emmanuel (1972) and Anderson (1976) have attempted to explain the uneven development of productive factors (mainly labour productivity) and the resulting income differences in the capitalist world by the means of the ‘surplus drain’ hypothes.

The balance of payments theory of rate of exchange has certain significant merits. Firstly, this theory attempts to determine the rate of exchange through the forces of demand and supply and thus brings exchange rate determination in purview of the general theory of value. Secondly, this theory relates the rate of exchange to the BOP situation. A criticism of a different nature is that PPP views the exchange rate is the determined variable and price levels as causal variables, whereas there are also chains of causation running from exchange rates to prices. The theory asserts that, the rate of exchange is the function of the supply of and demand for foreign money and not exclusively the function of prices obtaining between two countries as asserted by the Purchasing Power Parity Theory which does not take into account invisible items.
