This paper analyzes an exchange economy in which several assets serve as stores of value and where agents have completely heterogeneous preferences and endowments. It describes the set of perfect foresight equilibria in which all assets have positive prices. There are international policies with determinate exchange rates if the world economy satisfies a strong efficiency criterion. Also, the c...

We survey the recent empirical and theoretical developments in the literature on the relation between prices and exchange rates. After updating some of the major findings in the empirical literature we present a simple framework to interpret this evidence. We review theoretical models that generate insensitivity of prices to exchange rate changes through variable markups, both under flexible pr...

Kocherlakota and Pistaferri (2007) describe two different models (Private Information Pareto Optimal and Incomplete Markets) of how households partially insure themselves against idiosyncratic shocks. They demonstrate that the models differ in terms of their implications for real exchange rates. In this paper, we use data from a wide range of countries, and document that there is a statististic...

We consider two types of rms both operating in two countries. The demand side of the markets of the two countries are separated and each type of rm produces its good in one of these countries. We study the e ect of an exchange rate change on the competitive equilibrium prices in each country. When producing for the foreign market causes the same costs as producing for the home market then the `...

We propose a new model of exchange rates, which yields a theory of the forward premium puzzle. Our explanation combines two ingredients: the possibility of rare economic disasters, and an asset view of the exchange rate. Our model is frictionless, has complete markets, and works for an arbitrary number of countries. In the model, rare worldwide disasters can occur and affect each country’s prod...

Most of the large industrialized countries floated their exchange rates in early 1973, after the demise of the post-war Bretton Woods system of fixed exchange rates. While there have been extensive academic disputes over the relative merits of fixed and floating exchange rates, most discussions have been carried out on a largely hypothetical basis. The move to a generalized floating regime prov...
