This paper develops a simple but general methodology to estimate the expected intertemporal marginal rate of substitution or "EMRS", using only data on asset prices and returns. Our empirical strategy is general, and allows the EMRS to vary arbitrarily over time. A novel feature of our technique...

Typical evaluations of the choice of exchange rate regime employ a criterion function that depends on the real performance of the economy, and they focus on regimes that are expected to last indefinitely. This latter feature is strongly contradicted by the transitory nature of actual...

The management of the exchange rate is possible only if the government pursues a monetary-fiscal policy mix which is consistent with its exchange rate targets. In this paper with uncertainty concerning the length of individual life the real consequences of exchange rate management depend on the...

The collapse of a fixed exchange rate is typically marked by a sudden balance-of-payments crisis in which"speculators" fleeing from the domestic currency acquire a large portion of the central bank's foreign exchange holdings.Faced with such an attack, the central bank often withdraws...

The paper develops a model of exchange-rate and current-account determination for a small economy peopled by infinitely lived, utility-maximizing households. In this setting, a central-bank purchase of foreign exchange has no real effects when central-bank foreign reserves earn interest at the...

This paper investigates the long- and short-run neutrality of open-market monetary policy in a world of fixed exchange rates and imperfect substitutability between bonds denominated in different currencies. Using an illustrative portfolio-balance model, it shows that when the public discounts...

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

In recent years, many countries have instituted monetary reforms aimed at improving anti-inflation credibility. Is it a problem, however, that international welfare spillover effects seldom receive much consideration in the design of monetary reforms? Surprisingly, the answer may be no. Under...
