In this paper we develop a general model of an imperfectly competitive small open economy. There is a traded and non-traded sector, whose outputs are combined in order to produce a single final good that can be either consumed or invested. We make general assumptions about preferences and...

When firms borrow in foreign currency but collect revenues in local currency, exchange rate changes can affect their ability to repay their debt. Using loan-level data from U.S. banks' regulatory filings, this paper studies the effect of exchange rate changes on firms’ loan payments. A 10...

This paper analyses an open economy Ramsey model with an endogenous labour supply without capital. The technology defines an optimal firm size. Changes to the number of firms is subject to adjustment costs, so that the entry dynamics is determined endogenously. We find that there is a short run...

We present a unified dynamic framework to study the interconnections between international trade and business cycle models. We prove an aggregate equivalence between a competitive, representative firm model that has aggregate production externalities and dynamic trade models that feature...

We quantify the impact of barriers to international investment, using a novel multi-country dynamic general equilibrium model with heterogeneous investors and imperfect capital mobility. Our model yields a gravity equation for bilateral foreign asset positions. We estimate this gravity equation...

Ambitious climate policy, coupled with financial frictions, has the potential to create macrofinancial stability risk. Such stability risk may expand beyond the economy implementing climate policy, potentially catching other countries off guard. International spillovers may occur because of...
