This paper presents a systematic analysis of the purchasing power parity hypothesis (PPP). This hypothesis states that the exchange rate is equal to the ratio of the domestic price level to the foreign price level. It has recently been argued that PPP performs poorly in the 1970s. This paper...

This paper examines the conventional monetary equation of exchange rate determination. Under certain exogeneity conditions, one can write the price level, at home and abroad, as the ratio of the nominal money supply to the demand for real money balances. Then, since the exchange rate is the...

This paper provides an empirical examination of the hypothesis that the forward exchange rate provides an "optimal" forecast of the future spot ex-change rate, for five currencies relative to the dollar. This hypothesis provides a convenient norm for examining the erratic behavior of exchange...

Most studies of the efficiency of the foreign exchange market focus on a single maturity -- usually a one month exchange rate. However, one observes that forward contracts of many maturities are simultaneously traded in the foreign exchange market. The hypothesis that the foreign. exchange...

Exchange rates of currencies in the Exchange Rate Mechanism of the EMS are characterized by long periods of stability interrupted by periods of extreme volatility. The periods of volatility appear at times of realignments of the central parities and at times when the exchange rate is within the...

The relevance of imperfect competition for models of aggregate economic fluctuations has received increased attention from researchers in both macroeconomics and industrial organization. Measuring properly the size of industry markups of price over marginal cost is important both for assessing...

There has been a significant interest on a theoretical level in the application of supergames to oligopoly behavior. Implications for pricing behavior in trigger-strategy models in response to aggregate demand are of particular importance for public policy considerations. We contrast the...
