Book excerpt: We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity emphasized in the recent trade and macro literatures. Using Nielsen barcode data on prices and sales, we estimate elasticities of substitution within and between firms, and use the estimated model to recover unobserved qualities, marginal costs and markups. We find that variation in firm quality and product scope explains at least four fifths of the variation in firm sales. Most firms are well approximated by the monopolistic competition benchmark of constant markups, but the largest firms that account for most of aggregate sales depart substantially from this benchmark. Although the output of multiproduct firms is differentiated, cannibalization is quantitatively important for the largest firms. This imperfect substitutability of products within firms, and the fact that larger firms supply more products than smaller firms, implies that standard productivity measures are not independent of demand system assumptions and probably dramatically understate the relative productivity of the largest firms.

Book excerpt: Master's Thesis from the year 2015 in the subject Economics - International Economic Relations, grade: 2,0, University of Münster (Institute of International Economics), language: English, abstract: While the traditional Trade Theory is merely able to explain trade between developed and less developed countries, the more recent literature of the New Trade Theory allows for capturing trade between countries that are all highly developed. One of its models - the Melitz model of intra-industry trade (2003) - incorporates heterogeneity in firm productivity into a framework based on Krugman (1980). The Melitz model is a corner stone of New Trade Theory models and has been extended in various papers to analyze intra-industry trade with respect to different aspects. One important aspect that is covered intensively in recent literature is the efect of unilateral trade liberalization on a country's welfare. This thesis presents the Melitz model (2003) by firstly illustrating its fundament based onKrugman (1980) and secondly deriving its working mechanisms both for opening for trade as well as for trade liberalization. Further, extensions by Melitz and Ottaviano (2005) and Demidova and Rodriguez-Clarez (2011) will be presented. The thesis concludes by discussing the contribution of the Melitz model to explain occurring trading patterns and its limitations.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This paper sets out a basic heterogeneous-firms trade model that is closely akin to Melitz (2003). The positive and normative properties of the model are studied in a manner intended to highlight the core economic logic of the model. The paper also studies the impact of greater openness at the firm-level and aggregate level, focusing on changes in the number and type of firms, trade volumes and prices, and productivity effects. The normative effects of liberalisation are also studied and here the paper focuses on aggregate gains from trade, and income redistribution effects, showing inter alia that the model is marked by a Stolper-Samuelson like effect. A number of empirically testable hypotheses are also developed. These concern the impact of greater openness on the firm-level trade pattern, the variance of unit-prices, the stock market valuation of firms according to size, and the lobbying behaviour by size.

Available in PDF, EPUB and Kindle. Book excerpt: We measure the role of firm heterogeneity in counterfactual predictions of monopolistic competition trade models without parametric restrictions on the distribution of firm fundamentals. We show that two bilateral elasticity functions are sufficient to nonparametrically compute the counterfactual aggregate impact of trade shocks, and recover changes in economic fundamentals from observed data. These functions are identified from two semiparametric gravity equations governing the impact of bilateral trade costs on the extensive and intensive margins of firm-level exports. Applying our methodology, we estimate elasticity functions that imply an impact of trade costs on trade flows that falls when more firms serve a market because of smaller extensive margin responses. Compared to a baseline where elasticities are constant, firm heterogeneity amplifies both the gains from trade in countries with more exporter firms and the welfare gains of European market integration in 2003-2012.

Book excerpt: We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selection into trade, while accommodating asymmetries in trade flows. A new equation for the proportion of exporting firms takes a gravity form, such that the extensive margin is also affected by multilateral resistance. We develop Taylor approximated multilateral resistance terms with which to capture the comparative static effects of changes in trade costs. For isolated bilateral changes in trade frictions, multilateral resistance effects are small for most countries. However, if all countries reduce their trade frictions, the impact of multilateral resistance is so strong that bilateral trade falls in most cases, despite the larger trade elasticities implied by firm heterogeneity. As a consequence, the world-wide trade response, though positive, is much lower.

Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the response of industries and firms to changes in trade costs. Several new firm-level models of international trade with heterogeneous firms predict that industry productivity will rise as trade costs fall due to the reallocation of activity across plants within an industry. Using disaggregated U.S. import data, we create a new measure of trade costs over time and industries. As the models predict, productivity growth is faster in industries with falling trade costs. We also find evidence supporting the major hypotheses of the heterogenous-firm models. Plants in industries with falling trade costs are more likely to die or become exporters. Existing exporters increase their shipments abroad. The results do not apply equally across all sectors but are strongest for industries most likely to be producing horizontally-differentiated tradeable goods.

Book excerpt: This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional trade theories. We examine the implications of firm heterogeneity for comparative advantage, market size, aggregate trade, the welfare gains from trade, and the relationship between trade and income distribution. While a number of studies examine the endogenous response of firm productivity to trade liberalization, modeling internal firm organization and the origins of firm heterogeneity remain interesting areas of ongoing research.

Available in PDF, EPUB and Kindle. Book excerpt: International trade is dominated by a small number of very large firms. Models of trade with heterogeneous firms have been developed to study the causes and consequences of this observation. The canonical model of trade with heterogeneous firms shows that trade leads to between-firm reallocations and selection: it shifts employment towards firms with the best attributes and forces marginal firms to exit. The model also illustrates the role of heterogeneity, and its various sources, in explaining the volume of trade and the firm-level margins of adjustment. Consistent with the model, earlier empirical studies have documented that exporting is a rare activity, that exporting firms are larger and more productive than other firms, and that trade liberalization reallocates market shares towards the best-performing firms in various countries. More recent studies using transaction-level data have unveiled additional salient features of trade flows. First, sales by foreign firms are very heterogeneous and highly concentrated. Second, both the extensive margin (number of exporting firms) and the intensive margin (average export per firm) are important in explaining the level of exports and its changes over time. More heterogeneity in sales across firms is associated with a higher volume of trade along both margins. Third, increased foreign competition reallocates market shares towards top firms and hence can increase concentration from any country of origin. Numerous extensions of the benchmark model have been proposed to study other important aspects, such as the relevance of multi-product and multinational firms and the extent to which heterogeneity is endogenous to firms' choices, but some open challenges still remain.

Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews the empirical evidence on firm heterogeneity in international trade. A first wave of empirical findings from micro data on plants and firms proposed challenges for existing models of international trade and inspired the development of new theories emphasizing firm heterogeneity. Subsequent empirical research has examined additional predictions of these theories and explored other dimensions of the data not originally captured by them. These other dimensions include multi-product firms, offshoring, intra-firm trade and firm export market dynamics.

Available in PDF, EPUB and Kindle. Book excerpt: Essays by leading scholars suggest that insights from international business could enrich firm heterogeneity research in international economics. Despite their common roots, international economics (IE) and international business (IB) have developed into two distinct fields of study. Economists have directed their efforts at formalizing the workings of international trade and investment at the macroeconomic level; business scholars have relied more on data-driven conceptual narratives than mathematical tools. But the recent focus of IE literature on firm heterogeneity suggests that IE would benefit from IB analyses of the behavior and organization of the internationalizing firm. The contributions to this volume investigate ways that insights from IB can enrich IE research in firm heterogeneity. The contributors discuss firm-specific advantages in international trade and investment, considering the firm as the unit of analysis and managerial inputs as a variable in market entry decisions; analyze interactions between a firm and its external environment, including local corporate philanthropy and institutional settings; examine the boundaries of the firm and organizational choices such as the make-or-buy decision; and investigate technology transfer and innovation offshoring, discussing the role of subsidiaries, inventor employment, and other related topics. Although IE and IB look at international firms from different perspectives, these contributions make it clear that there is a potential for a productive exchange of insights and information between the two disciplines.

Book excerpt: This paper builds a tractable partial equilibrium model in the spirit of Melitz (2003), which incorporates two dimensions of heterogeneity: firms specific productivity shocks and firm-market specific demand shocks. The structural parameters of interest are estimated using only cross-sectional data, and counterfactual experiments regarding the effects of reducing costs, both fixed and marginal, or of trade preferences (with distortionary Rules of Origin) offered by an importing country are performed. Our counterfactuals make a case for "trade as aid," as such polices can create a win-win scenario and are less subject to the usual worries regarding the efficacy of direct foreign aid.
