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...

This paper addresses the question of reform of the international monetary system. It starts by identifying the sources of disenchantment with the performance of the present regime of floating exchange rates and by outlining the reasons for the lack of convergence of views about the...

This paper deals with the relations among international liquidity,the exchange-rate regime and the effectiveness of monetary policy. The first part of the paper contains an empirical study of the demand for international reserves. It is shown that (i) reserve holdings are a stable function of a...

This paper argues that macroeconomic policies for open economies differ, in fundamentally important ways, from the corresponding policies for closed economies.The openness of the economy imposes constraints on the effectiveness and proper conduct of macroeconomic policies and it also provides...

This paper reviews and analyzes the empirical record of exchange rates and prices during the 1970's and the analysis is based on the experience of the Dollar/Pound, the Dollar/French Franc and the Dollar/DM exchange rates. Section 2 presents the evidence on PPP during the 1970's and contrasts it...

This paper summarizes the results of an empirical study of the operation of flexible exchange rates during the 1920's under both the hyperinflationary conditions (based on the experience of Germany) and under the normal conditions (based on the experience of Britain, the United States and...

The 1970's witnessed the dramatic evolution of the international monetary system from a regime of pegged exchange rates into a regime of flexible rates. This paper surveys the key issues and lessons from the experience with floating rates during the1970's. The main orientation is empirical and...
