The elasticity of substitution between goods from different countries---the Armington elasticity---is important for many questions in international economics, but its magnitude is subject to debate: the "macro" elasticity between home and import goods is often found to be smaller than the...

Since the September 1985 Plaza Hotel announcement by the Group of Five industrial countries, a substantial realignment of exchange rates has been achieved. At the same time, foreign exchange market intervention, much of it concerted and much of it sterilized, has been undertaken on a scale not...

When the goals of internal and external macroeconomic equilibrium are in conflict, sterilized intervention in the foreign exchange market may provide an independent policy instrument through which the central bank can resolve its dilemma in the short run. This paper is concerned with the West...

The purpose of this paper is two fold. First, to estimate, using structural methods, the extent to which capital flows undermined West German monetary policy during the Bretton Woods years 1960 to 1970 and second, to show that earlier reduced form estimates of the capital-account offset...

Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. In an earlier paper, we showed that this reasoning does...

There is a large and growing empirical literature that tests forthe existence of asset-price bubbles or quot;sunspotquot; equilibria -- equilibria unrelated to market fundamentals. Our view is that even tests for non-stationary asset-price bubbles should not be interpreted as such. In the...

This paper shows that the optimal extraction of seigniorage implies a strong tendency for inflation to fall over time toward its socially optimal level. The point is made using a multi-period model in which (i) the government can finance deficits through bond issue or money creation, (ii)...

Even when the exchange-rate plays no expenditure-switching role, countries may wish to have flexible exchange rates in order to free the domestic interest rate as a stabilization tool. In a setting with nontraded goods, exchange-rate movements may also enhance international risk sharing

This paper present some new empirical evidence on the extent of world capital-market integration. The first set of tests carried out uses data from different countries to compare internationally expected marginal rates of substitution between consumption on different dates. If residents of...

Several puzzling aspects of the behavior of United States stock prices can be explained by the presence of a specific type of rational bubble that depends exclusively on dividends. We call such bubbles quot;intrinsicquot; bubbles because they derive all of their variability from exogenous...
