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...

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...

When information about fundamentals is symmetric, can information-based trade still arise? Consider bond and FX markets, where private information about nominal cash flows is generally absent, but participants are convinced that superior information exists. We analyze a class of asymmetric...

We model dynamic mechanisms for a global commons. Countries benefit from both consumption and aggregate conservation of an open access resource. A country's relative value of consumption-to-conservation is privately observed and evolves stochastically. An optimal quota maximizes world welfare...

This paper formulates a dynamic model of global carbon consumption in the absence of an effective international agreement. Each period, countries extract carbon from the global ecosystem. A country's output depends both on its carbon usage and on the ecosystem ("stored carbon"). The desired mix...

Between 1995 and 2008, the European Union and the United States raised environmental standards and concurrently experienced important reductions in emissions from manufacturing despite a rise in output. Levinson (2009) finds that the offshoring of polluting industries to countries with lower...

We develop and estimate an household search model to evaluate if ignoring that labor market decisions are taken at the household level - as usually done in search models of the labor market - has relevant empirical consequences. We evaluate the impact of this potential mispecification error by...

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...
