This paper conducts a Cox-type survival analysis of Japanese corporate firms using census-coverage data collected by METI. A study of exiting firms confirmed several characteristics of Japanese firms in the 1990s. First, excessive internalization in the corporate structure and activities is...

How does growing international financial diversification affect firm-level and aggregate labor shares? We study this question using a novel framework of firm labor choice in the face of aggregate risk. The theory implies a cross-section of labor risk premia and labor shares that appear as...

Multinational firms (MNEs) dominate trade flows, yet their global production decisions are often ignored in firm-level studies of exporting and importing. Using newly merged data on US firms' trade and multinational activity by country, we show that MNEs are more likely to trade not only with...

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...

Free trade or preferential trade areas (PTAs) allow importers who belong to the area to export to each other while paying zero or preferential tariffs as long as Rules of Origin (ROOs) are met. Meeting them is costly not only in terms of production costs but also in terms of documentation costs....

I explore whether the world trading system of the twentieth century can be adapted to address the challenges of the twenty-first. I first develop an understanding of how GATT functioned during the twentieth century, and which features of the economic environment were most important in...

We examine how export expansion induced by the U.S-Vietnam Bilateral Trade Agreement (BTA) affected migration, school enrollment, work and healthcare use of young children and adolescents in Vietnam. To do so, we exploit variation in tariff reductions across industries associated with the BTA...

Trade policy uncertainty (TPU) has become an important source of economic uncertainty and research. We review the main sources and measures of TPU. We then provide a conceptual framework for modeling TPU and methods of estimating and quantifying its effects. We analyze its role in trade...

The design of a trade agreement should reflect its purpose. Does digital trade change the purpose of a trade agreement? To explore this question, I first describe the definitional and classification issues associated with digital trade, and for modeling purposes I adopt a simple taxonomy of the...

We study whether tariff preferences conferred on South Korean goods through the implementation of the Korea-U.S. Free Trade Agreement (KORUS) drew U.S. import demand away from other U.S. trading partners through the phenomenon known as trade diversion. In the two years following the...
