This paper examines how country, industry and firm characteristics interact in general equilibrium to determine nations' responses to trade liberalization. When firms possess heterogeneous productivity, countries differ in relative factor abundance and industries vary in factor intensity, falling trade costs induce reallocations of resources both within and across industries and countries. These reallocations generate substantial job turnover in all sectors, spur relatively more creative destruction in comparative advantage industries than comparative disadvantage industries, and magnify ex ante comparative advantage to create additional welfare gains from trade. The relative ascendance of high-productivity firms within industries boosts aggregate productivity and drives down consumer prices. In contrast with the neoclassical model, these price declines dampen and can even reverse the real wage losses of scarce factors as countries liberalize.
John Sutton sets out a unified theory that encompasses two major approaches to studying market, while generating a series of novel predictions as to how markets evolve. Traditionally, the field of industrial organization has relied on two unrelated theories—the cross-section theory and the growth-of-firms theory—to explain cross-industry differences in concentration and within-industry skewness. The two approaches are based on very different mathematical structures and few researchers have attempted to relate them to each other. In this book, John Sutton unifies the two approaches through a theory that rests on three simple principles. The first two, a "survivor principle" that says that firms will not pursue loss-making strategies, and an "arbitrage principle" that says that if a profitable opportunity is available, some firm will take it, suffice to define a set of possible outcomes. The third, the "symmetry principle," says that the strategy used by a new entrant into any submarket depends neither on the entrants identity nor on its history in other submarkets. This allows researchers to bring together the roles of strategic interactions and of independence effects. The result is that the considerations motivating the cross-section tradition and those motivating the growth-of-firms tradition both drop out within a single game-theoretic model. This book follows Sutton's Sunk Costs and Market Structure, published by MIT Press in 1991.
Economic and social progress requires a diverse ecosystem of firms that play complementary roles. Making It Big: Why Developing Countries Need More Large Firms constitutes one of the most up-to-date assessments of how large firms are created in low- and middle-income countries and their role in development. It argues that large firms advance a range of development objectives in ways that other firms do not: large firms are more likely to innovate, export, and offer training and are more likely to adopt international standards of quality, among other contributions. Their particularities are closely associated with productivity advantages and translate into improved outcomes not only for their owners but also for their workers and for smaller enterprises in their value chains. The challenge for economic development, however, is that production does not reach economic scale in low- and middle-income countries. Why are large firms scarcer in developing countries? Drawing on a rare set of data from public and private sources, as well as proprietary data from the International Finance Corporation and case studies, this book shows that large firms are often born large—or with the attributes of largeness. In other words, what is distinct about them is often in place from day one of their operations. To fill the “missing top†? of the firm-size distribution with additional large firms, governments should support the creation of such firms by opening markets to greater competition. In low-income countries, this objective can be achieved through simple policy reorientation, such as breaking oligopolies, removing unnecessary restrictions to international trade and investment, and establishing strong rules to prevent the abuse of market power. Governments should also strive to ensure that private actors have the skills, technology, intelligence, infrastructure, and finance they need to create large ventures. Additionally, they should actively work to spread the benefits from production at scale across the largest possible number of market participants. This book seeks to bring frontier thinking and evidence on the role and origins of large firms to a wide range of readers, including academics, development practitioners and policy makers.
This paper studies the macroeconomic effect and underlying firm-level transmission channels of a reduction in business entry costs. We provide novel evidence on the response of firms' entry, exit, and employment decisions. To do so, we use as a natural experiment a reform in Portugal that reduced entry time and costs. Using the staggered implementation of the policy across the Portuguese municipalities, we find that the reform increased local entry and employment by, respectively, 25% and 4.8% per year in its first four years of implementation. Moreover, around 60% of the increase in employment came from incumbent firms expanding their size, with most of the rise occurring among the most productive firms. Standard models of firm dynamics, which assume a constant elasticity of substitution, are inconsistent with the expansionary and heterogeneous response across incumbent firms. We show that in a model with heterogeneous firms and variable markups the most productive firms face a lower demand elasticity and expand their employment in response to increased entry.
I develop a model of firm-to-firm search and matching to show that the impact of falling trade costs on firm sourcing decisions and consumer welfare depends on the relative size of search externalities in domestic and international markets. These externalities can be positive if firms share information about potential matches, or negative if the market is congested. Using unique firm-to-firm transaction-level data from Uganda, I document empirical evidence consistent with positive externalities in international markets and negative externalities in domestic markets. I then build a dynamic quantitative version of the model and show that, in Uganda, a 25% reduction in trade costs led to a 3.7% increase in consumer welfare, 12% of which was due to search externalities.
The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank’s Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50 percent of variation in exports is along the extensive margin—a quantitative victory for the Melitz framework. The remaining 50 percent on the intensive margin (exports per exporting firm) contradicts a special case of Melitz with Pareto-distributed firm productivity, which has become a tractable benchmark. This benchmark model predicts that, conditional on the fixed costs of exporting, all variation in exports across trading partners should occur on the extensive margin. We find that moving from a Pareto to a lognormal distribution allows the Melitz model to match the role of the intensive margin in the EDD. We use likelihood methods and the EDD to estimate a generalized Melitz model with a joint lognormal distribution for firm-level productivity, fixed costs and demand shifters, and use “exact hat algebra” to quantify the effects of a decline in trade costs on trade flows and welfare in the estimated model. The welfare effects turn out to be quite close to those in the standard Melitz-Pareto model when we choose the Pareto shape parameter to fit the average trade elasticity implied by our estimated Melitz-lognormal model, although there are significant differences regarding the effects on trade flows.
In many countries, a sizable share of international trade is carried out by intermediaries. While large firms tend to export to foreign markets directly, smaller firms typically export via intermediaries (indirect exporting). I document a set of facts that characterize the dynamic nature of indirect exporting using firm-level data from Vietnam and develop a dynamic trade model with both direct and indirect exporting modes and customer accumulation. The model is calibrated to match the dynamic moments of the data. The calibration yields fixed costs of indirect exporting that are less than a third of those of direct exporting, the variable costs of indirect exporting are twice higher, and demand for the indirectly exported products grows more slowly. Decomposing the gains from indirect and direct exporting, I find that 18 percent of the gains from trade in Vietnam are generated by indirect exporters. Finally, I demonstrate that a dynamic model that excludes the indirect exporting channel will overstate the welfare gains associated with trade liberalization by a factor of two.
Global Production is the first book to provide a fully comprehensive overview of the complicated issues facing multinational companies and their global sourcing strategies. Few international trade transactions today are based on the exchange of finished goods; rather, the majority of transactions are dominated by sales of individual components and intermediary services. Many firms organize global production around offshoring parts, components, and services to producers in distant countries, and contracts are drawn up specific to the parties and distinct legal systems involved. Pol Antràs examines the contractual frictions that arise in the international system of production and how these frictions influence the world economy. Antràs discusses the inevitable complications that develop in contract negotiation and execution. He provides a unified framework that sheds light on the factors helping global firms determine production locations and other organizational choices. Antràs also implements a series of systematic empirical tests, based on recent data from the U.S. Customs and Census Offices, which demonstrate the relevance of contractual factors in global production decisions. Using an integrated approach, Global Production is an excellent resource for researchers, graduate students, and advanced undergraduates interested in the inner workings of international economics and trade.
