August 1971 - December 1976. It is contended that their short-term exchange rate equations provide a convenient vehicle for exposition of the policy problems faced by monetary authorities on exchange rate decisions. This empirical work is extended in Branson et al. (1979) to include the exchange rates in 1977 and 1978, inwhich they show and discuss the workings of the equations in detail. It is demonstrated that although the original equation estimated on the 1971-1976 data over predicts the dollar value of the Deutsch mark for most of 1978, the rise of the Deutsch mark is consistent with the ‘fundamentals’ equation. Dooley and Isard (1982) develop a model in which current account imbalances can be ‘financed’ through transfers of bonds denominated in either domestic or foreign currency The current spot exchange rate is linked to the expected future spot exchange rate via a risk premium, which depends on the global currency mix of outside assets that governments impose on private portfolios through budget deficits and interventions and on the global distribution of private wealth among regions with different portfolio preferences. Using monthly data starting in March 1973 and end ing in December 1977, their iterative procedure generates rational expectations
