An information externality exists in the foreign exchange market due to the fact that traders play two partially conflicting roles: (i) each is a speculator and (ii) each is an information clearinghouse in that each intermediates own-customer orders which convey information. Profit maximization...

I test three potentially complementary models in an effort to capture the fundamentals that underlaid the market's determination of Peru's floating exchange rate through the period 1950-54: the first is an expectational purchasing power parity (PPP) model which maintains that asset market forces...

This article presents an overview of research on the Microstructure of Foreign Exchange Markets. We begin by summarizing the institutional features of FX trading and describe how they have evolved since the 1980s. We then explain how these features are represented in microstructure models of FX...

I develop and estimate a general equilibrium model for the term structures of nominal and real interest rates in the UK that incorporates Markov-switching. The model allows for non- neutralities, nonlinear dynamics, and flexibility in the dynamics of the risk premia - features that are all...

his paper studies the effects of financial integration on macroeconomic volatility and welfare. We examine a two-sector (tradable and nontradable), two-country world economy with production in which both stocks and bonds are traded internationally, but markets are incomplete. The effects of...

This paper presents a new numerical method for solving stochastic general equilibrium models with dynamic portfolio choice over many financial assets. The method can be applied to models where there are heterogeneous agents, time-varying investment opportunity sets, and incomplete asset markets....

The aim of this paper is to establish the link between the high frequency dynamics of spot exchange rates and developments in the macroeconomy. To do so, I first present a theoretical model of exchange-rate determination that bridges the gap between existing microstructure and traditional...

We provide an overview of micro-based research using models of currency trading set in a partial equilibrium setting, and in the general equilibrium setting of modern macroeconomic models. In so doing we aim to dispel the myth that micro-based research is solely focused on the details of...

This article summarizes exchange-rate research using microstructure models. It first lays out the key features of the foreign exchange market and describes how they are incorporated into a canonical model of currency trading. The empirical implications of the model are then examined. The article...

This paper studies the dynamics of the U.S. external position for the past 35 years, and examines alternative paths for future external adjustment. We develop a new present value expression for the external position that embeds the restrictions of international solvency and can be easily...
