A model that contains no costs to changing prices but in which prices do not respond to nominal shocks is presented. In models that do not feature superneutrality of money flexible price equilibria will allow certain types of monetary shocks to affect the real economy. Sticky price behavior may...

The drift of two different diffusion processes (asset returns) is determined by a state variable which can take on two values. It jumps between the two according to Poisson increments (this is called a 'regime-switch'). For any given position of the state variable the drift of one process is...

In late 1993 and early 1994, the wholly-owned U.S. subsidiary of a German conglomerate experienced substantial losses in connection with the implementation of a petroleum marketing strategy, triggering an emergency recapitalization of the German parent company. The rescue was overseen by the...

The most widely accepted explanation for the inverse association between private investments and current accounts [Glick and Rogoff, 1995] rests on data for manufactures through 1990. Is this consensus robust to revisions to the national accounts and the expansion of information technologies...

We consider monetary-policy rules with inflation-rate targets and interest-rate or money-growth instruments using a flexible-price, perfect-foresight model. There is always a locally-unique target equilibrium. There may also be below-target equilibria (BTE) with inflation always below target and...

This paper addresses the question: do risk premia account for the observed time-varying discrepancies between forward and corresponding future spot exchange rates? A simple theoretical framework is used to derive testable restrictions on the parameters of a multivariate regression model. Using...

Failures of the law of one price explain much of the variation in real C.P.I. exchange rates. We use C.P.I. data for U.S. cities and Canadian cities for 14 categories of consumer prices to examine the nature of the deviations from the law of one price. The distance between cities explains a...

We formulate an optimizing-agent model in which both labor and product markets exhibit monopolistic competition and staggered nominal contracts. The unconditional expectation of average household utility can be expressed in terms of the unconditional variances of the output gap, price inflation,...

We investigate the role of "country risk" in determining the default risk of firms in emerging markets. In particular, we study the relationship between the secondary market spreads (over hard-currency government bond yields) of bonds issued by emerging market firms and bonds issued by their...

For G-7 countries over the period 1961-1990, there appears to be a strong and stable negative correlation between annual changes in the current account and investment. Here we explore this correlation using a highly tractable empirical model that distinguishes between global and country-specific...
