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.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this article we propose a new methodology for computing the aggregate productivity of an industry, its variations and decompositions of the latter into changes of individual productivities (within effect) and changes in industry composition (between effect). Current aggregate measures rely on some weighted average of individual productivities, and decompositions distinguish between the effect of productivities and weights on variations of the average. However such aggregate measure is incoherent with the disaggregate one (the two are computed with different methodologies), is subject to aggregation biases, arbitrariness in the choice of weights, and information loss. Such problems are particularly serious when heterogeneity among firms is high. We propose instead a geometric approach where aggregate productivity can be measured directly on industry data, but nevertheless its variations can be decomposed into between and within effects plus an heterogeneity effect. We show that our measure does not incur in many of the problems of the weighted average and we also present an empirical application to European data.
Download or read book The Impact of Trade on Aggregate Productivity and Welfare with Heterogeneous Firms and Business Cycle Uncertainty written by and published by . This book was released on 2008 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a model with monopolistic competition, productively heterogeneous firms, and business cycle aggregate shocks. With firm-specific productive heterogeneity, weaker firms quit when faced with a negative aggregate shock. Consequently, trade does not always increase firm-level aggregate productivity as negative shocks on the home market can be compensated for by positive shocks elsewhere. Weaker firms, which would otherwise quit in autarky, can continue to operate by exporting. Despite this, trade can still improve welfare for risk-averse consumers by reducing aggregate price fluctuations.

Available in PDF, EPUB and Kindle. Book excerpt: Despite the microeconomic evidence supporting the superior idiosyncratic productivity of multinational firms (MFN) and their affiliates, cross-country studies fail to find robust evidence of a positive relationship between Foreign Direct Investment and growth. In order to study the aggregate implications of MNF entry and production, I develop a Dynamic Stochastic General Equilibrium model with firm heterogeneity where MNF sort according to their own productivity. Entry and production of MNF contribute to aggregate productivity growth at decreasing rates over time but potentially crowd out domestic producers due to increased product and factor market competition. I compare the aggregate benefit of productivity contributions with the cost of crowding out and argue that composition and crowding-out effects can help explain the conflicting evidence on the impact of Foreign Direct Investment on growth.
Download or read book Occupational Choice Aggregate Productivity and Trade written by Jürgen Meckl and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We propose occupational decisions of heterogeneous individuals as an alternative mechanism of explaining the distribution of firm productivities emphasized by empirical studies. Thus, we integrate the frameworks of Melitz (Econometrica 71 (2003):1695-725), and of Manasse and Turrini (Journal of International Economics 54 (2001):97-117) that establish the theoretical base of trade models with heterogeneous firms. Our model is technically much simpler than the Melitz approach while preserving the main results on firm-selection effects caused by international market integration. Our approach paves the way for detailed analysis of institutions in a heterogeneous firm model to better understand the link between institutions and an economy's productivity distribution.

Book excerpt: We develop a monopolistically competitive model of trade with firm heterogeneity - in terms of productivity differences - and endogenous differences in the 'toughness' of competition across markets - in terms of the number and average productivity of competing firms. We analyze how these features vary across markets of different size that are not perfectly integrated through trade; we then study the effects of different trade liberalization policies. In our model, market size and trade affect the toughness of competition, which then feeds back into the selection of heterogeneous producers and exporters in that market. Aggregate productivity and average markups thus respond to both the size of a market and the extent of its integration through trade (larger, more integrated markets exhibit higher productivity and lower markups). Our model remains highly tractable, even when extended to a general framework with multiple asymmetric countries integrated to different extents through asymmetric trade costs. We believe this provides a useful modeling framework that is particularly well suited to the analysis of trade and regional integration policy scenarios in an environment with heterogeneous firms and endogenous markups.

This book was released on 2019-11-27 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: We assess the aggregate productivity impact of distortions arising from labor regulations in Mexico and how they interact with informality. Using employment surveys and a firm-level economic census, we document a number of novel features about informal firms in Mexico. We then construct and estimate a model of heterogeneous firms and endogenous informality to study the micro and macro impacts from various policy reforms. Some reforms may have large impacts on informal employment but small impacts on aggregate productivity.

Book excerpt: This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry reallocations of resources following trade liberalization, and patterns of trade participation across firms and destination markets. Accounting for these empirical patterns reveals new mechanisms through which the aggregate economy is affected by trade liberalization, including endogenous increases in average industry and firm productivity.
Download or read book Falling Trade Costs Heterogeneous Firms and Industry Dynamics written by Andrew B. Bernard and published by . This book was released on 2003 with total page 50 pages. 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.
Download or read book Multi product Firms and Trade Liberalization written by Andrew B. Bernard and published by . This book was released on 2006 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper develops a general equilibrium model of multi-product firms and analyzes their behavior during trade liberalization. Firm productivity in a given product is modeled as a combination of firm-level "ability" and firm-product-level "expertise", both of which are stochastic and unknown prior to the firm's payment of a sunk cost of entry. Higher firm-level ability raises a firm's productivity across all products, which induces a positive correlation between a firm's intensive (output per product) and extensive (number of products) margins. Trade liberalization fosters productivity growth within and across firms and in aggregate by inducing firms to shed marginally productive products and forcing the lowest-productivity firms to exit. Though exporters produce a smaller range of products after liberalization, they increase the share of products sold abroad as well as exports per product. All of these adjustments are shown to be relatively more pronounced in countries' comparative advantage industries.

This book was released on 2011-04-01 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper tests the effect of comparative advantage, size, and networking on the firm probability of exporting. The closest theoretical framework is the one of Bernard, Redding, and Schott (2007), with firm heterogeneity across countries and industries. We use a recently assembled multi-country multi-industry firm level dataset, and construct original measures of comparative advantage. The results show that firms are more likely to export if they belong to the comparative advantage industry, if they enjoy a higher productivity, or if they benefit from foreign, domestic, or communication networks.

Available in PDF, EPUB and Kindle. Book excerpt: "We develop a stochastic, general equilibrium, two-country model of trade and macroeconomic dynamics. Productivity differs across individual, monopolistically competitive firms in each country. Firms face a sunk entry cost in the domestic market and both fixed and per-unit export costs. Only relatively more productive firms export. Exogenous shocks to aggregate productivity and entry or trade costs induce firms to enter and exit both their domestic and export markets, thus altering the composition of consumption baskets across countries over time. In a world of flexible prices, our model generates endogenously persistent deviations from PPP that would not exist absent our microeconomic structure with heterogeneous firms. It provides an endogenous, microfounded explanation for a Harrod-Balassa-Samuelson effect in response to aggregate productivity differentials and deregulation. Finally, the model successfully matches several moments of U.S. and international business cycles"--NBER website
