Antràs, Pol, and Ricardo Caballero. 2009. “Trade and Capital Flows: A Financial Frictions Perspective.” Journal of Political Economy 117 (4): 701-44. DOI:10.1086/605583 Abstract
The classical Heckscher-Ohlin-Mundell paradigm states that trade and capital mobility are substitutes in the sense that trade integration reduces the incentives for capital to flow to capital-scarce countries. In this paper we show that in a world with heterogeneous financial development, a very different conclusion emerges. In particular, in less financially developed economies (South), trade and capital mobility are complements in the sense that trade integration increases the return to capital and thus the incentives for capital to flow to South. This interaction implies that deepening trade integration in South raises net capital inflows (or reduces net capital outflows). It also implies that, at the global level, protectionism may backfire if the goal is to rebalance capital flows.

Cambridge, MA: Harvard University Press. Harvard University Press Abstract
Why do firms decide to offshore certain parts of their production process? What qualities certain countries as particularly attractive locations to offshore? In this paper we address these questions with a theory of international production hierarchies in which organizations arise endogenously to make efficient use of agents' knowledge. Our theory highlights the role of host-country management skills (middle management) in bringing about the emergence of international offshoring. By shielding top management in the source country from routine problems faced by host country workers, the presence of middle managers improves the efficiency of the transmission of knowledge across countries. The model further delivers the prediction that the positive effect of middle skills on offshoring is weaker, the more advanced are communication technologies in the host country. We provide evidence consistent with this prediction.

Antràs, Pol, and Elhanan Helpman. 2008. “Contractual Frictions and Global Sourcing.” The Organization of Firms in a Global Economy, edited by Elhanan Helpman, T Verdier, and D Marin, 9-54. Cambridge, MA: Harvard University Press. Harvard University Press Abstract
We generalize the Antràs and Helpman (2004) model of the international organization of production in order to accommodate varying degrees of contractual frictions. In particular, we allow the degree of contractibility to vary across inputs and countries. A continuum of firms with heterogeneous productivities decide whether to integrate or outsource the production of intermediate inputs, and from which country to source them. Final-good producers and their suppliers make relationship-specific investments which are only partially contractible, both in an integrated firm and in an arm's-length relationship. We describe equilibria in which firms with different productivity levels choose different ownership structures and supplier locations, and then study the effects of changes in the quality of contractual institutions on the relative prevalence of these organizational forms. Better contracting institutions in the South raise the prevalence of offshoring, but may reduce the relative prevalence of FDI or foreign outsourcing. The impact on the composition of offshoring depends on whether the institutional improvement affects disproportionately the contractibility of a particular input. A key message of the paper is that improvements in the contractibility of inputs controlled by final-good producers have different effects than improvements in the contractibility of inputs controlled by suppliers.

We develop a tractable framework for the analysis of the relationship between contractual incompleteness, technological complementarities, and technology adoption. In our model, a firm chooses its technology and investment levels in contractible activities by suppliers of intermediate inputs. Suppliers then choose investments in noncontractible activities, anticipating payoffs from an ex post bargaining game. We show that greater contractual incompleteness leads to the adoption of less advanced technologies, and that the impact of contractual incompleteness is more pronounced when there is greater complementary among the intermediate inputs. We study a number of applications of the main framework and show that the mechanism proposed in the paper can generate sizable productivity differences across countries with different contracting institutions, and that differences in contracting institutions lead to endogenous comparative advantage differences.

We develop a dynamic bargaining model in which a leading country endogenously decides whether to sequentially negotiate free trade agreements with subsets of countries or engage in simultaneous multilateral bargaining with all countries at once. We show how the structure of coalition externalities shapes the choice between sequential and multilateral bargaining, and we identify circumstances in which the grand coalition is the equilibrium outcome, leading to worldwide free trade. A model of international trade is then used to illustrate equilibrium outcomes and how they depend on the structure of trade and protection. Global free trade is not achieved when the political-economy motive for protection is sufficiently large. Furthermore, the model generates both “building bloc” and “stumbling bloc” effects of preferential trade agreements. In particular, we describe an equilibrium in which global free trade is attained only when preferential trade agreements are permitted to form (a building bloc effect), and an equilibrium in which global free trade is attained only when preferential trade agreements are forbidden (a stumbling bloc effect). The analysis identifies conditions under which each of these outcomes emerges.

How does the formation of cross-country teams affect the organization of work and the structure of wages? To study this question, we propose a theory of the assignment of heterogeneous agents into hierarchical teams, where less skilled agents specialize in production and more skilled agents specialize in problem solving. We first analyze the properties of the competitive equilibrium of the model in a closed economy, and show that the model has a unique and efficient solution. We then study the equilibrium of a two-country model (North and South), where countries differ in their distributions of ability, and in which agents in different countries can join together in teams. We refer to this type of integration as globalization. Globalization leads to better matches for all southern workers but only for the best northern workers. As a result, we show that globalization increases wage inequality among nonmanagers in the South, but not necessarily in the North. We also study how globalization affects the size distribution of firms and the patterns of consumption and trade in the global economy.

Antràs, Pol. 2005. “Incomplete Contracts and the Product Cycle.” American Economic Review 95 (4): 1054-73. DOI:10.1257/0002828054825600 Abstract
The incomplete nature of contracts governing international transactions limits the extent to which the production process can be fragmented across borders. In a dynamic, general-equilibrium Ricardian model of North-South trade, the incompleteness of international contracts is shown to lead to the emergence of product cycles. Because of contractual frictions, goods are initially manufactured in the North, where product development takes place. As the good matures and becomes more standardized, the manufacturing stage of production is shifted to the South to benefit from lower wages. Following the property-rights approach to the theory of the firm, the same force that creates product cycles, i.e., incomplete contracts, opens the door to a parallel analysis of the determinants of the mode of organization. The model gives rise to a new version of the product cycle in which manufacturing is shifted to the South first within firm boundaries, and only at a later stage to independent firms in the South. Relative to a world with only arm’s length transacting, allowing for intrafirm production transfer by multinational firms is shown to accelerate the shift of production towards the South, while having an ambiguous effect on relative wages. The model delivers macroeconomic implications that complement the work of Krugman (1979), as well as microeconomic implications consistent with the findings of the empirical literature on the product cycle.

I present new estimates of the elasticity of substitution between capital and labor using data from the private sector of the U.S. economy for the period 1948-1998. I first adopt Berndt's (1976) specification, which assumes that technological change is Hicks neutral. Consistently with his results, I estimate elasticities of substitution that are not significantly different from one. I next show, however, that restricting the analysis to Hicks-neutral technological change necessarily biases the estimates of the elasticity towards one. When I modify the econometric specification to allow for biased technical change, I obtain significantly lower estimates of the elasticity of substitution. I conclude that the U.S. economy is not well described by a Cobb-Douglas aggregate production function. I present estimates based on both classical regression analysis and time series analysis. In the process, I deal with issues related to the nonsphericality of the disturbances, the endogeneity of the regressors, and the nonstationarity of the series involved in the estimation.

We present a North-South model of international trade in which differentiated products are developed in the North. Sectors are populated by final-good producers who differ in productivity levels. On the basis of productivity and sectoral characteristics, firms decide whether to integrate into the production of intermediate inputs or outsource them. In either case they have to decide from which country to source the inputs. Final-good producers and their suppliers must make relationship-specific investments, both in an integrated firm and in an arm’s-length relationship. We describe an equilibrium in which firms with different productivity levels choose different ownership structures and supplier locations. We then study the effects of within-sectoral heterogeneity and variations in industry characteristics on the relative prevalence of these organizational forms.

This paper presents new estimates of total factor productivity growth in Britain for the period 1770–1860. We use the dual technique and argue that the estimates we derive from factor prices are of similar quality to quantity-based calculations. Our results provide further evidence, calculated on the basis of an independent set of sources, that productivity growth during the British Industrial Revolution was relatively slow. The Crafts–Harley view of the Industrial Revolution is thus reinforced. Our preferred estimates suggest a modest acceleration after 1800.

Roughly one-third of world trade is intrafirm trade. This paper starts by unveiling two systematic patterns in the volume of intrafirm trade. In a panel of industries, the share of intrafirm imports in total U.S. imports is significantly higher, the higher the capital intensity of the exporting industry. In a cross-section of countries, the share of intrafirm imports in total U.S. imports is significantly higher, the higher the capital-labor ratio of the exporting country. I then show that these patterns can be rationalized in a theoretical framework that combines a Grossman-Hart-Moore view of the firm with a Helpman-Krugman view of international trade. In particular, I develop an incomplete-contracting, property-rights model of the boundaries of the firm, which I then incorporate into a standard trade model with imperfect competition and product differentiation. The model pins down the boundaries of multinational firms as well as the international location of production, and it is shown to predict the patterns of intrafirm trade identified above. Econometric evidence reveals that the model is consistent with other qualitative and quantitative features of the data.
