Both papers in this session try to discriminate between various theories of the determination of exchange rates. The null hypothesis of the Brittain paper is that monetary factors are not relevant in the determination of exchange rates. After examining some of the implications of current monetary models he rejects the null hypothesis. The Sargen paper sets out to explain the empirical observation that in the floating exchange rate period some rates were highly volatile while others seemed to be quite stable. He examines the implications of two alternative theories. He finds that the Purchasing Power Parity (PPP) theory as extended by Girton & Roper is not quite adequate in explaining exchange rate fluctuations, but that it explains reserve changes quite well. The Aliber-Dornbusch-McKinnon approach, which is the alternative theory, implies that structural parameters of the economy will influence exchange rate volatility. He then proceeds to estimate these parameters and finds that they are not sufficiently different across countries to account for the differences in exchange rate volatility. [ABSTRACT FROM AUTHOR]
