Firms play a central role in the selection, sponsorship, and employment of skilled immigrants entering the United States for work through programs like the H-1B visa. This role has not been widely recognized in the literature, and the data to better understand it have only recently become...

This paper studies the impact that immigrant innovators have on the global activities of U.S. firms by analyzing detailed data on patent applications and on the operations of the foreign affiliates of U.S. multinational firms. The results indicate that increases in the share of a firm's...

Despite the rapid expansion of U.S.-China trade ties, the increase in U.S. FDI in China, and the expanding amount of economic research exploring these developments, a number of misconceptions distort the popular understanding of U.S. multinationals in China. In this paper, we seek to correct...

In this paper, we extend the growth model to include firm-specific technology capital and use it to assess the gains from opening to foreign direct investment. A firm's technology capital is its unique know-how from investing in research and development, brands, and organization capital. What...

We examine the home bias of international knowledge spillovers as measured by the speed of patent citations (i.e. knowledge spreads slowly over international boundaries). We present the first compelling econometric evidence that the geographical localization of knowledge spillovers has fallen...

Each of the world's largest retailers---Walmart, Carrefour, Tesco, and Metro---entered China after 1995. Their subsequent expansion in China may have influenced Chinese exports through two channels. First, they may have enhanced bilateral exports between the retailers' Chinese operations and...

This paper develops a framework to analyze the relationship between the diffusion of new technologies and the decentralization decisions of firms. Centralized control relies on the information of the principal, which we equate with publicly available information. However, the manager can use her...

Support for R&D subsidies relies on empirical evidence that R&D "spills over" between firms. But firm performance is affected by two countervailing R&D spillovers: positive effects from technology spillovers and negative business stealing effects from R&D by product market rivals. We develop a...

Although it is evident that R&D has undergone a process of internationalization, and that the less-advanced economies are becoming increasingly involved in this process, the substantial body of literature in this area has been based largely on the experiences of the developed countries. This...

Empirical studies on information communication technologies (ICT) typically aggregate the "information" and "communication" components together. We show theoretically and empirically that these have very different effects on the empowerment of employees, and by extension on wage inequality. If...
