Two central insights from the Schumpeterian approach to innovation and growth are that the pace of innovation is endogenously determined by the expectation of future profits and that growth is inherently a process of creative destruction. As international trade is a key determinant of firm...

We generalize the closed-economy neoclassical growth model (CNGM) to allow for costly goods trade and capital flows with imperfect substitutability between countries. We develop a tractable, multi-country, quantitative model that matches key features of the observed data (e.g., gravity equations...

Research in international trade has changed dramatically over the last twenty years, as attention has shifted from countries and industries towards the firms actually engaged in international trade. The now-standard heterogeneous firm model posits measure zero firms that compete under...

We examine US workers' employment and earnings before and after trade liberalization with China. Among workers initially employed in manufacturing, we find substantial and persistent declines in both outcomes, with indirect exposure via input-output linkages exacerbating the negative effects of...

Since the 1990s, R&D has become less geographically concentrated, and has seen especially fast growth in emerging markets. One of the distinguishing features of the R&D globalization phenomenon is its concentration within the software/IT domain; the increase in foreign R&D has been largely...

The location of US multinational foreign R&D has shifted significantly to include emerging markets in addition to traditional Western R&D hubs, resulting in two challenges for multinationals: (1) how to transfer knowledge across geographic distances, and (2) how to facilitate learning when local...

This paper studies how international trade influences U.S. presidential elections. We expect the positive employment effects of expanding exports to increase support for the incumbent's party, and job insecurity from import competition to diminish such support. Our national-level models show for...

We examine firm participation in global supply chains to help explain a puzzling decline in protectionist demands in the U.S. despite increased import competition and ongoing currency undervaluation. To explain firm responses to undervaluation, we rely on advances in the international trade...

This paper reviews recent research on geography and trade. One of the key empirical findings over the last decade has been the role of geography in shaping the distributional consequences of trade. One of the major theoretical advances has been the development of quantitative spatial models that...

This paper analyzes China's experience under U.S. apparel and textile quotas. It makes use of a unique new database that tracks U.S. trading partners' performance under the quota regimes established by the global Multifiber Arrangement (1974 to 1995) and subsequent Agreement on Textiles and...
