Title: Purchasing Power Parity: A Survey of the Issues
Abstract: The purchasing power parity (PPP) doctrine, one of the most widely researched areas in international finance, is also probably one of the most controversial in the theory of exchange rate determination. According to the theory of purchasing power parity, the rate of exchange between two currencies is determined by the differences in the price levels of their respective countries. However, while proponents of the theory argue that PPP provides a strong basis for determining exchange rates, others have contended otherwise, with a plethora of empirical research demonstrating persistent deviations from PPP. Consequently, we provide a survey of the issues that contribute to the problems in testing the theory. Notably, factors such as the lack of uniformity in the price indices used to determine the long-run equilibrium exchange rate — also known as the 'index-number problem' — and the issue of productivity bias, which is probably seen as the most serious criticism of PPP theory, are discussed. We also consider the role of market imperfections as well as structural changes in the economy.KeywordsExchange RateGross Domestic ProductReal Exchange RatePurchase Power ParityNominal Exchange RateThese keywords were added by machine and not by the authors.
