We propose a dynamic general equilibrium model of exchange rate determination, which simultaneously accounts for all major puzzles associated with nominal and real exchange rates. This includes the Meese-Rogoff disconnect puzzle, the PPP puzzle, the terms-of-trade puzzle, the Backus- Smith...

This paper studies the welfare implications of trade opening in a world in which trade raises aggregate income but also increases income inequality, and in which redistribution needs to occur via a distortionary income tax-transfer system. We provide tools to characterize and quantify the...

How strong are strategic complementarities in price setting across firms? In this paper, we provide a direct empirical estimate of firm price responses to changes in prices of their competitors. We develop a general framework and an empirical identification strategy to estimate the elasticities...

We show that the exchange rate may appreciate or depreciate depending on the specific mix of sanctions imposed, even if the underlying equilibrium allocation is the same. Sanctions that limit a country's imports tend to appreciate the country's exchange rate, while sanctions that limit exports...

We propose a theory of inattention solely based on preferences, absent any cognitive limitations, or external costs of acquiring information. Under disappointment aversion, information decisions and risk attitude are intertwined, and agents are intrinsically information averse. We illustrate...

We argue that buyout waves form in response to fluctuations in aggregate discount rates. In our model, discount rates alter the present value of cash flow improvements and the illiquidity premium demanded by buyout investors. We confirm our predictions empirically. Overall deal activity varies...

We discover a novel monetary policy shock that has a widespread impact on aggregate financial conditions. Our shock can be summarized by the response of long-horizon yields to Federal Open Market Committee (FOMC) announcements; not only is it orthogonal to changes in the near-term path of policy...

I study the dynamics of asset prices in an economy in which investors choose whether to hold diversified or concentrated portfolios of risky assets. The latter are valuable, as they increase the productivity of the correspond- ing enterprises. I capture the tradeoff between risk sharing and...
