I provide novel evidence for the impact of trade policy uncertainty on exporters. In a dynamic, heterogeneous firms model, trade policy uncertainty will delay the entry of exporters into new markets and make them less responsive to applied tariff reductions. Policy instruments that reduce or...

We document several new features of firms' export entry and exit behaviors: i) one-third of exporting firms enter into and exit from exporting multiple times; ii) most continuing exporters enter and exit specific export destinations multiple times; iii) firms re-entering exporting often sell the...

Existing models of offshoring are not equipped to explain how global production sharing affects the volatility of economic activity. This paper develops a trade model that can account for why offshoring industries in low wage countries such as Mexico experience fluctuations in employment that...

This paper develops an information-based theory of international currency based on search frictions, private trading histories, and imperfect recognizability of assets. Using an open-economy search model with multiple competing currencies, the value of each currency is determined without...

We provide a synoptic description of financial crises and the multilateral response over the course of the last four decades. We present both indicators of economic performance around crisis dates and a comprehensive description of multilateral rescue efforts. While emergency lending has grown,...

Numerous studies have documented substantial deviations from the law of one price for consumer goods. However, in most cases small transaction costs can explain these violations. In our study, we purposely focus on a market where such frictions are minimal, namely online bookselling in the US...

This paper considers the relation between immigration and prices in a number of countries across the world over the period from 1990 to 2006. Immigration is shown to have a negative impact on international relative prices. A 10% increase in the share of immigrant workers in total employment...

The last twenty years have witnessed periods of sustained appreciations of the real exchange rate in emerging economies. The case of Mexico between 1988 and 2002 is representative of several episodes in Latin America and Central and Eastern Europe in which countries opening to capital flows...

In theory, nominal exchange rate movements can lead to “expenditure switching” when they generate changes in the relative prices of goods across countries. This paper explores whether the expenditure-switching role of exchange rates has changed in the current episode of significant global...

Motivated by recent empirical work, this paper formalizes a theory of competitive savings — an arms race in household savings for mating competition that is made more fierce by an increase in the male-to-female ratio in the pre-marital cohort. Relative to the empirical work, the theory can...
