This paper presents a general approximation method for characterizing time-varying equilibrium portfolios in a two-country dynamic general equilibrium model. the method can be easily adapted to most dynamic general equilibrium models, it applies to environments in which markets are complete or...

This paper proposes a concept of a global currency and introduces a "global currency pricing" specification into a standard N-country open economy macroeconomic model. A global currency is defined as a virtual unit of account that is exclusively used for international trade invoicing and is...

We quantify the macroeconomic effects of the tariff measures announced (but not entirely implemented yet) on Liberation Day (April 2nd, 2025) through the lens of a New-Keynesian two-country model calibrated to the US and the rest of the world. We study both a unilateral 10pp tariff increase and...

This paper explores the relationship between exchange rate adjustment and trade policy in a simple New Keynesian open economy macro model. We show that movement in exchange rates have a direct implication for trade policy when governments choose tariffs endogenously. In particular, we show that...

This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in stabilising the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

This paper develops a model of endogenous exchange rate pass-through within an open economy macroeconomic framework, where both pass-through and the exchange rate are simultaneously determined, and interact with one another. Pass-through is endogenous because firms choose the currency in which...

The literature on optimal capital controls for macro-prudential policy has focused on capital controls in a small open economy. This ignores the spillover effects to the rest of the world. This paper re-examines the case for capital controls in a large open economy, where domestic financial...
