The field of international trade has undergone significant theoretical and empirical advancements over the last twenty-five years. A key breakthrough has been the emergence of firm-level approaches to studying exporting, importing, and global value chains. The field has also experienced a...

Products with negative externalities are often subject to regulations that limit competition. The single-product case may suggest that it is irrelevant for aggregate welfare whether output is restricted via corrective taxes or limiting competition. However, when products are differentiated...

We introduce a general quantifiable framework to study the location decisions of multinational firms. In the model, firms choose in which locations to pay the fixed costs of setting up production, taking into account potential complementarities among production locations. The firm's location...

The rise of artificial intelligence (AI) and of cross-border restrictions on data flows has created a host of new questions and related policy dilemmas. This paper addresses two questions: How is digital service trade shaped by (1) AI algorithms and (2) by the interplay between AI algorithms and...

What are a country's policy options in the face of emerging technologies development in a global economy? To answer this question, we examine optimal dynamic policies in an open economy where technology is endogenously accumulated through R&D innovation. Our key insight is that a country has...

Hegemonic powers, like the United States and China, exert influence on other countries by threatening the suspension or alteration of financial and trade relationships. Mechanisms that generate gains from integration, such as external economies of scale and specialization, also increase the...

We examine the potential role of international agreements on product standards through a stylized model where countries have different regulatory preferences and firms incur fixed costs of regulatory diversity. Overall, our analysis suggests that the common perception of regulatory agreements as...

I study the equilibrium and the welfare effects of international trade when product markets are imperfectly competitive due of search frictions--as in Burdett and Judd (1983)--rather than product differentiation--as in Dixit and Stiglitz (1977). Markups are positive, even though there are...

We use Brazilian administrative employer-employee matched data of worker demographics, industry of affiliation, occupation, and wages to examine whether females in managerial and executive positions (cracks in the glass ceiling) lead to more gender-equal workplace outcomes. In response to the...

We estimate a model of firm export dynamics featuring cross-country complementarities. The firm decides where to export by solving a dynamic combinatorial discrete choice problem, for which we develop a solution algorithm that overcomes the computational challenges inherent to the large...
