Domestic regulation,import penetration and firm-level productivity growth

This paper shows that the impact of import penetration on firms’ productivity growth depends on firms’ distance to the efficiency frontier and on product market regulation. Using firm-level data for a substantial number of OECD countries from the late 1990s to late 2000s, the analysis reveals nonlinear effects of both sectoral import penetration and de jure product market regulation measures, depending on firms’ positions along the global distribution of productivity. Close to the technology frontier, import penetration has a strongly positive effect on firm-level productivity growth, with less stringent domestic regulation enhancing this effect substantially. However, far from the frontier, the effect of import penetration on firm-level productivity growth is much smaller and often not significant. Its interaction with domestic regulation generally has no statistically significant effect either. The heterogeneous effects of import penetration and domestic product market regulation on firm-level productivity growth are consistent with a neo-Schumpeterian view of trade and regulation.     

Entry to foreign markets and productivity: Evidence from a matched sample of Turkish manufacturing firms

We examine the effects of international trading activities of firms on creating productivity gains in Turkey by using a recent firm-level data set over the period 2003–2010. We establish treatment models and investigate the productivity improvements of firms through trade by using propensity score matching techniques together with difference-in-difference estimates. Three different groups of treatment are constructed: (1) firms that are involved only with import activities, (2) firms that are involved only with export activities and (3) firms that are involved with both export and import activities. The results of the study suggest that both exporting and importing have positive significant effects on total factor productivity (TFP) and labour productivity (LP) of firms. Importing is found to have a greater impact on productivity of firms compared to exporting. Further, two-way trade is found to have more significant effects than those of one-way trade on firm productivity. Finally, our results indicate that international trade has greater impact on LP rather than TFP of firms.     

Wage Effects of Trade Reform with Endogenous Worker Mobility

In this paper, we use a linked employer–employee database from Brazil to evaluate the wage effects of trade reform. With an aggregate (firm-level) analysis of this question, we find that a decline in trade protection is associated with an increase in average wages in exporting firms relative to domestic firms, consistent with earlier studies. However, using disaggregated, employer–employee level data, and allowing for the endogenous assignment of workers to firms due to match-specific productivity, we find that the premium paid to workers at exporting firms is economically and statistically insignificant, as is the differential impact of trade openness on the wages of workers at exporting firms relative to otherwise identical workers at domestic firms. We also find that workforce composition improves systematically in exporting firms, in terms of the combination of worker ability and the quality of worker–firm matches, post-liberalization. These results stand in stark contrast to the findings reported in many earlier studies and underscore the importance of endogenous matching and, more generally, non-random labor market allocation mechanisms, in determining the effects of trade policy changes on wages.     

The impact of trade liberalization on productivity: Evidence from India's formal and informal manufacturing sectors

Despite a large literature investigating the impacts of trade on firm productivity, there is almost no evidence on how small firms react to trade liberalization. Using a unique dataset of firm-level surveys that are representative of the entire Indian manufacturing industry, I show that India's unilateral reduction in final goods tariffs increased the average productivity of small, informal firms, which account for 80% of Indian manufacturing employment but have been excluded from previous studies. In contrast, the increase in productivity among larger, formal firms was driven primarily by the concurrent reduction in input tariffs. By examining the effect of the tariff liberalization on the distributions of productivity and firm size, I find evidence consistent with the exit of the smallest, least productive firms from the informal sector. In addition, I find that although the decline in final goods tariffs did not significantly impact average formal sector productivity, it did increase productivity among the top quantiles of the distribution.

Technology gap,imported capital goods and productivity of manufacturing plants in Sub-Saharan Africa

This paper uses firm-level data from Ghana, Tanzania and Kenya to examine the effect of capital goods imports on domestic firms' productivity, and the role firms' technology gap plays in aiding the transmission of knowledge embodied in capital goods to domestic firms. The results show that increasing imports of capital goods and closing technology gaps have positive effects on productivity. Furthermore, domestic firms with technology standards farther from international best practices benefit more from capital goods imports. The results also imply that trade liberalization policy aimed at eliminating tariffs on capital goods will significantly improve the performance of technically incompetent firms in the African manufacturing sector.     

Structural estimation and solution of international trade models with heterogeneous firms

We present an empirical implementation of a general-equilibrium model of international trade with heterogeneous manufacturing firms. The theory underlying our model is consistent with Melitz (2003). A nonlinear structural estimation procedure identifies a set of core parameters and unobserved firm-level trade frictions that best fit the geographic pattern of trade. Our estimation model is consistent with the specified general equilibrium model, and we conduct general equilibrium counterfactual analyses to illustrate model responses. We first assess the economic effects of reductions in measured tariffs. Taking the simple-average welfare change across regions the Melitz structure indicates welfare gains from liberalization that are four times larger than in a standard trade policy simulation. Furthermore, when we compare the economic impact of tariff reductions with reductions in estimated fixed trade costs we find that policy measures affecting the fixed costs are of greater importance than tariff barriers.

The impact of trade on aggregate productivity and welfare with heterogeneous firms and business cycle uncertainty

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 the risk-averse consumer by reducing aggregate price fluctuations.     

International trade in services: A portrait of importers and exporters

We provide a novel set of stylized facts on firms engaging in international trade in services, using unique data on firm-level exports and imports from the world's second largest services exporter, the United Kingdom (UK). We show that only a fraction of UK firms engage in international trade in services, that trade participation varies widely across industries and that service traders are different from non-traders in terms of size, productivity and other firm characteristics. We also provide detailed evidence on the trading patterns of service exporters and importers, such as the number of markets served, the value of exports and imports per market and the share of individual markets in overall sales. We interpret these facts in the light of existing theories of international trade in services and goods. Our results demonstrate that firm-level heterogeneity is a key feature of services trade. Also, we find many similarities between services and goods trade at the firm level and conclude that existing heterogeneous firm models for goods trade will be a good starting point for explaining trade in services as well.     

Cherries for sale: The incidence and timing of cross-border M&A

This paper develops a model of cross-border M&A activity that features firm-level productivity shocks and endogenous export activity. We show that foreign firms will be relatively more attracted to targets in the domestic country that had high productivity levels that induced them to invest in large export networks several years prior to acquisition, but subsequently experienced a negative productivity shock (i.e., cherries for sale). From the theory we derive a dynamic panel binary choice empirical model to predict cross-border M&A activity, and find strong evidence for our hypotheses connecting the evolution of firm-level productivity to the ultimate targets of cross-border acquisitions using French firm-level data.

Trade policy under firm-level heterogeneity in a small economy

We explore the effect of trade policy on productivity and welfare in the now standard model of firm-level heterogeneity and product differentiation with monopolistic competition. To obtain sharp results, we restrict attention to an economy that takes as given the price of imports and the demand schedules for its exports (a “small economy”). We first establish that welfare can be decomposed into four terms: productivity, terms of trade, variety and curvature, where the last is a term that captures heterogeneity across varieties. We then show how a consumption subsidy, an export tax, or an import tariff allows our small economy to deal with two distortions that we identify and thereby reach its first-best allocation. We also show that an export subsidy generates an increase in productivity, but given the negative joint effect on the other three terms (terms of trade, variety, and curvature), welfare falls. In contrast, an import tariff improves welfare in spite of the fact that productivity falls.     

Foreign acquisition and post-privatization exit of state-owned firms

This paper analyzes the impact of foreign and domestic ownership on the exit rates of privatized state-owned enterprises (SOEs) in transitional countries. The exit of privatized SOEs can have a profound impact on employment and on the development of local economies of transitional countries. An oligopoly model that incorporates country-level trade costs and individual SOE's productivity is developed to assess the exit of SOEs under either foreign or domestic ownership. The model shows that market competition between firms can lead to liquidation of the SOE by a domestic firm when trade costs increase. When the productivity of SOE is high, neither foreign nor domestic firm will liquidate. The predictions of the model are tested using firm-level privatization data from Central and Eastern Europe. By controlling for productivity, trade costs, and other attributes of SOEs after privatization, it is found that foreign ownership significantly reduces the probability of SOE's exit as compared to domestic ownership. Furthermore, there is evidence that as trade costs increase, the exit probability of domestically owned SOEs increases and the exit probability of foreign-owned SOEs declines.     

The role of intermediaries in facilitating trade

This paper documents that intermediaries play an important role in facilitating international trade. We modify a heterogeneous firm model to allow for an intermediary sector. The model predicts that firms will endogenously select their mode of export - either directly or indirectly through an intermediary - based on productivity. The model also predicts that intermediaries will be relatively more important in markets that are more difficult to penetrate. We provide empirical confirmation for these predictions using the firm-level census of China's trade, and generate new facts regarding the activity of intermediaries. We also provide evidence that firms begin to export directly after exporting through intermediaries.     

A simple model of firm heterogeneity, international trade, and wages

This paper presents a general equilibrium trade model in which homogeneous firms choose a technology from a set of competing technologies and choose employees from a set of workers of heterogeneous skill. In equilibrium, the interaction between the characteristics of competing technologies, international trade costs, and the availability of workers of heterogeneous skill gives rise to firm heterogeneity. The model generates several of the stylized facts concerning the (apparent) superiority of firms that engage in international trade relative to those that do not and has implications for the effect of international trade on the skill premium and on observed industry-level productivity.     

Internationalization choices and Italian firm performance during the crisis

We focus on the relationship between internationalization choices and performance of Italian firms during the first period of the financial crisis (2007–2010). Making use of a new firm-level database, we build a six-class taxonomy of firms’ internationalization activities; then we estimate firms’ performance as a function of internationalization forms, also estimating propensity score and Heckman selection models in order to control for endogeneity and sample selection bias. Over the period 2007–2010, Italian firms moved (on average) towards more complex forms of internationalization. Empirical analysis finds that these upward changes are related with positive effects on firms’ (labour) productivity, also in a period characterized by the 2009 trade collapse. These findings put additional emphasis on the issue of the diversification of both products and markets as a goal to be pursued by firms, even in times of crisis, to remain competitive and make profits.     

International trade,risk taking and welfare

This paper shows that the gains from opening up to international trade are smaller when firms do not fully internalize downward risk. I develop a general equilibrium model with two key assumptions. First, when faced with adverse productivity shocks, employers can lay off workers without fully paying the social costs of their layoff decisions, a common feature of many institutions. Second, when opening to international trade, the elasticity of demand perceived by an industry increases. In this setup, I show that international trade induces firms to take more risk and (i) raises the equilibrium unemployment rate, (ii) increases the volatility of sectoral sales and (iii) increases welfare proportionately less than in the absence of the externality. Inducing firms to internalize the costs of layoff (Blanchard and Tirole, 2003) therefore appears even more important in a globalized world.
