This paper reports the results of an empirical study of the industry and country determinants of U.S. outward foreign direct investment (FDI). These results contribute to the literature in two dimensions. First, they demonstrate that the structure of U.S. FDI reflects an interaction between country skilled-labor abundance and industry skilled-labor intensities that is consistent with comparative advantage. Second, they confirm the results of early studies that market access plays an important role in the structure of U.S. FDI. Together these results paint a broad picture of the structure of U.S. FDI that casts light on the predictions of the theory of multinational enterprise.

We estimate international technology spillovers to U.S. manufacturing firms via imports and foreign direct investment (FDI) between 1987 and 1996. In contrast to earlier work, our results suggest that FDI leads to substantial productivity gains for domestic firms. The size of FDI spillovers is economically important, accounting for about 14% of productivity growth in U.S. firms between 1987 and 1996. FDI spillovers are particularly strong in high-tech sectors, whereas they are largely absent in low-tech sectors. Small firms with low productivity benefit more from FDI spillovers than larger productivity firms with more productivity do. The evidence for import spillovers is much weaker.

How large are spatial barriers to transferring knowledge? We analyze the international operations of multinational firms to answer this fundamental question. In our model firms can transfer bits of knowledge to their foreign affiliates in either embodied (traded intermediates) or disembodied form (direct communication). Knowledge transfer costs interact with the knowledge intensity of production to determine the geographic structure of multinationals' input sourcing as well as its competitiveness in foreign markets. The model shows how data on observable trade costs and features of multinationals'global operations reveal the size and nature of knowledge transfer costs. Our empirical analysis confirms the model's predictions using firm-level data, quantifies the aggregate implications of the model for the structure of multinationals' operations, and demonstrates that transfer costs shape the knowledge content of intra-firm trade flows.

We develop an assignment theory to analyse the volume and composition of foreign direct investment (FDI). Firms conduct FDI by either engaging in greenfield investment or in cross-border acquisitions. Cross-border acquisitions involve firms trading heterogeneous corporate assets to exploit complementarities, while greenfield FDI involves setting up a new production division in the foreign country. In equilibrium, greenfield FDI and cross-border acquisitions coexist within the same industry, but the composition of FDI between these modes varies with firm and country characteristics. Firms engaging in greenfield investment are systematically more efficient than those engaging in cross-border acquisitions. Furthermore, most FDI takes the form of cross-border acquisitions when production-cost differences between countries are small, while greenfield investment plays a more important role for FDI from high-cost into low-cost countries. These results capture important features of the data.

Multinational sales have grown at high rates over the last two decades, outpacing the remark-able expansion of trade in manufactures. Con-sequently, the trade literature has sought to incorporate the mode of foreign market access into the “new ” trade theory. This literature rec-ognizes that firms can serve foreign buyers through a variety of channels: they can export their products to foreign customers, serve them through foreign subsidiaries, or license foreign firms to produce their products. Our work focuses on the firm’s choice be-tween exports and “horizontal ” foreign direct investment (FDI). Horizontal FDI refers to an investment in a foreign production facility that

We develop a quantifiable general equilibrium model of trade and multinational production (MP) in which countries can specialize in innovation or production. Home market effects or comparative advantage leads some countries to specialize in innovation and relegate manufacturing operations to other countries via outward MP. Counterfactual analysis reveals that the reduction in the cost of MP or the integration of China into the world economy may hurt countries that are driven to specialize in production, although these losses tend to be very small. Contrary to popular fears, production workers gain even in countries that further specialize in innovation.

This paper presents theory and evidence from disaggregated Chinese data that tariff reductions induce a country’s producers to upgrade the quality of their exports. We first document stylized facts regarding the effect of trade liberalization on export prices. Next, we develop an analytic framework that relates a firm’s choice of quality to its access to imported intermediates. In the model, a reduction in import tariffs induces a firm to increase export quality and raise its export price in industries where the scope for quality differentiation is large and lower its export price in industries where the scope is small. The predictions are consistent with the stylized facts and are highly robust econometrically.

International transactions are costly because they require investments in logistics, contracts, and the acquisition of local institutional knowledge. We posit that a portion of the fixed cost of entering a specific export market can be used toward covering the cost of acquiring imported inputs from that same market, and vice versa. Using dis-aggregated transactions data for Chinese firms from 2000 to 2015, we document firm-level trading patterns suggesting such bilateral economies of scope. Through a structural model, we estimate that the simultaneous export and import in a given country reduce export and import fixed costs by around 42 and 35 percent, respectively.
