Macroeconomic models of nominal exchange rates perform poorly. In sample, R2 statistics as high as 10 percent are rare. Out of sample, these models are typically out-forecast by a naïve random walk. This paper presents a model of a new kind. Instead of relying exclusively on macroeconomic...

This paper presents a new model for studying international capital flows and debt dynamics. The model emphasizes the role of expectations concerning future trade flows and returns as the determinants of a country's foreign asset and liability positions, and how revisions in these expectations...

Since 2013 regulators have been investigating the activities of some of the world's largest banks around the setting of daily benchmarks for forex prices. These benchmarks are a key linchpin of world financial markets, providing standardize prices used to value global equity and bond portfolios,...

This paper describes a new analytical framework for the quantitative assessment of international external positions. The framework links each country's current net foreign asset position to its current trade flows, forecasts of future trade flows, and expectations concerning future returns on...

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

This paper addresses international financial integration in a new way. We focus on informational integration, specifically, the importance of information conveyed by order flow in major currencies for pricing minor currencies. We develop a multi-currency model of portfolio allocation in the...

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...

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...

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...
