Trade Intermediation and the Organization of Exporters

Empirical papers show that successful exporting firms either use unaffiliated foreign trade intermediaries or own foreign wholesale subsidiaries. However, conventional trade theory models assume that producers can directly access foreign consumers. We introduce intermediaries in an international trade model where producers differ with respect to productivity as well as regarding their varieties' perceived quality and tradability. Trade intermediation is prone to frictions owing to the absence of enforceable cross‐country contracts while own wholesale subsidiaries require additional capital investment. The sorting pattern of firms depends on their degree of competitive advantage; the equilibrium prevalence of intermediation in the industry depends negatively on the heterogeneity among producers, and the market‐specificity of goods, and positively on expropriation risk. Using sectoral US export data by destination country, we confirm the empirical validity of these predictions.     

Local export spillovers in France

This paper investigates the presence of local export spillovers on both the extensive (the decision to start exporting) and the intensive (the export volume) margins of trade, using data on French individual export flows, at the product-level and by destination country, between 1998 and 2003. We investigate whether the individual decision to start exporting and exported volume are influenced by the presence of nearby product and/or destination specific exporters, using a gravity-type equation estimated at the firm-level. Spillovers are considered at a fine geographical level corresponding to employment areas (348 in France). We control for the new economic geography-type selection of firms into agglomerated areas, and for the local price effects of firms agglomeration. Results show evidence of the presence of export spillovers on the export decision but not on the exported volume. We interpret this as a first evidence of export spillovers acting through the fixed rather than the variable cost. Spillovers on the decision to start exporting are stronger when specific, by product and destination, and are not significant when considered on all products-all destinations. Moreover, export spillovers exhibit a spatial decay within France: the effect of other exporting firms on the export decision is stronger within employment areas and declines with distance.     

Market size and entry in international trade: Product versus firm fixed costs

This paper develops a theoretical framework to infer the nature of fixed costs from the relationship between entry patterns in international markets and destination market size. If fixed costs are at the firm level, firms take advantage of an intrafirm spillover by expanding firm‐level product range (scope). Few firms enter with many products and dominate international trade. If fixed costs are at the product level, an interfirm spillover reduces the fixed costs to export for all firms producing the product. The resulting entry pattern consists of many firms exporting different varieties of the same product. Using cross‐country data on firm and product entry, I find empirical evidence consistent with product‐level costs. More firms than products enter in larger markets offering their consumers lower prices and a greater variety of goods within the product category.     

Is export diversification good for profitability? First evidence for manufacturing enterprises in Germany

This article uses a tailor-made newly available data set for enterprises from manufacturing industries in Germany to investigate for the first time the links between export diversification over destination countries and goods on the one hand and the profitability of the exporting firms on the other hand. We find that profits tend to be larger in firms with less diversified export sales over goods and in firms with more diversified export sales over destination countries.     

What explains indirect exports of goods and services in Eastern Europe and Central Asia?

This paper investigates the determinants of indirect exporting, using firm-level data for 27 countries in Eastern Europe and Central Asia. Indirect exporting depends on a combination of fixed and variable trade cost factors. We first hypothesize that firms that perceive customs, transportation, crime and legal systems as severe obstacles anticipate higher fixed costs and are more likely to export indirectly. The second hypothesis is that indirect exporting tends to be a temporary strategy. Econometric models are used to test the first hypothesis and transition matrices to test the second. In particular, probit, Heckman-probit and fractional response models are estimated to analyse the determinants of the export mode and the share of indirect exports. The results indicate that the factors that account for the fixed cost of exporting, mainly affect the decision to export indirectly (extensive margin), but some of them also affect, to a lesser extent, the amount exported indirectly (intensive margin). More specifically, factors such as customs and trade restrictions and transportation obstacles affect the extensive margin only, whereas crime affects both margins. Secondly, trade agreement membership mainly affects trade in manufactured goods, while exchange rate volatility affects positively the extensive and intensive margin of indirect exports of services. The results also indicate that firms are more likely to change their status as an indirect exporter than they are to change their status as a direct exporter or a non-exporter, which provides support to the second hypothesis.     

Exporters in cross‐section: Direct versus intermediated trade

How do producers that export their goods directly differ from those that export through trade intermediaries? We take a standard model of trade with heterogeneous firms and add heterogeneity in quality to the usual heterogeneity in productivity. Modeling trade intermediaries as increasing marginal costs but decreasing fixed costs of exporting, we find that only firms with the highest quality‐adjusted productivity levels choose to export directly. Under certain parameter restrictions, the model shows that direct exporters tend to be larger and charge higher prices for their goods. In contrast to the literature, using Chinese customs data, we confirm that direct exporters do charge higher prices for their goods.     

Wholesalers in international trade

Recent empirical research in international trade has revealed overwhelming evidence that, in all countries, a remarkably small proportion of firms report exports in Customs statistics. However, a large share of these are wholesalers. This suggests that the number of producers selling their products abroad might be much greater than that suggested by a simple count of the firms directly reporting their exports. This paper sheds light on the role of wholesalers in international trade. Our model uses very general assumptions to show that intermediated exporters may contribute significantly to the extension of countries' export opportunities. The model predicts a twofold role in international trade. First, wholesalers alleviate the difficulty of reaching less-accessible markets. Second, they help less-efficient firms to supply foreign markets, thus increasing the number of exported varieties at the aggregate level. We use French firm-level export data to provide empirical support for these two predictions.     

Export Destination,Product Quality and Wages in a Middle‐Income Country. The Case of South Africa

A robust finding in the firm‐level literature is that exporting firms pay higher wages. Using South African data this paper investigates the relationship between export destination and wages at a worker level. South Africa, a middle‐income country, has two distinct main export markets—a regional market where per capita incomes are lower than at home, and an international market with higher per capita incomes. Our estimates show that workers in firms that export to the region earn less than those that produce for the domestic market. Those in firms that export outside the region earn more than either domestic producers or region‐only exporters. Much of this difference in wages can be explained by the premium the different types of exporters pay for skills. These results support previous studies which suggest that export destination is related to product quality which in turn is related to worker quality and therefore wages.     

Who Exports Better Quality Products to Smaller or More Distant Markets?

The role of across‐firm differences in product quality and firms' competitiveness in determining the spatial patterns of within‐product export unit values across destinations is examined in this paper. Using product level export data, it is shown that the average export unit value of a product shipped from the USA or Korea increases with distance and decreases with destination market's size. However, within‐product average unit values for products exported from China and India decrease with distance and increase with market size. To interpret these different spatial patterns of unit values across exporting countries, model of quality heterogeneity is developed in which firms differ in their workers' skill level and higher‐skilled workers show greater productivity in performing tasks that improve product quality. The model predicts that in relatively skill‐abundant countries, exporting firms specialize in high‐quality products using relatively cheap skilled labor, whereas, in relatively skill‐scarce countries, firms that produce lower‐quality products are more competitive.     

Trade and productivity: Self-selection or learning-by-exporting in India

Recent literature tried to explain the Indian growth miracle in different ways, ranging from trade liberalization to industrial reforms. Using data on Indian manufacturing firms, this paper analyzes the relationship between firm's productivity and export market participation during 1991–2004. While it provides evidence of the self-selection hypothesis by showing that more productive firms become exporters, the results do not show that entry into export markets enhances productivity. The paper examines the explanation of self selection hypothesis for total factor productivity differences across 33,510 exporting and non-exporting firms. It uses propensity score matching to test the learning-by-exporting hypothesis. In line with the prediction of recent heterogeneous firm models of international trade, the main finding of the paper is: more productive firms become exporters but it is not the case that learning by exporting is a channel fuelling growth in Indian manufacturing.     

Does export and productivity growth linkage exist? Evidence from the Indian manufacturing industry

This paper examines the interrelation between exporting and productivity performance by using a representative sample of Indian manufacturing firms over the period 1994–2006. Specifically, we attempt to test the empirical validity of the learning‐by‐exporting and the self‐selection hypotheses for our sample firms. In order to investigate the linkage, in the first step, we test for causality between TFP and export intensity of firms. Although overall results are rather mixed and provide some support for both hypotheses, still the empirical results are more favorable for the self‐selection behavior of firms. In the next stage, we attempt to provide evidence on export and productivity linkage that occurs during various phases of transition in the export market. Our results suggest that entering in the export market does not improve productivity performance. However, the decision to exit from the export market does have an adverse effect on the productivity. In addition, our results indicate the presence of a high sunk cost of exporting coupled with perhaps lesser information about foreign markets. Finally, our results also lend some support to the significant role of in‐house research activities and economies of scale in firms' productivity performance.

The impact of trade promotion services on Canadian exporter performance

From 1999 to 2006, Canadian firms successfully diversified their exports to destinations beyond the United States while smaller firms increased their share in total exports. Both are explicit aims of the Trade Commissioner Service export promotion program. Exploiting assumptions from the treatment effects literature, we identify a causal, export‐boosting effect. In contrast with existing evidence for Latin American countries, the intensive margin effect—higher exports to existing product‐destination markets—dominates. Effects at the extensive margin—exporting more products to more destinations—are smaller and sensitive to identification assumptions. We interpret this evidence in light of trade models with heterogeneous firms.     

The Impact of Exporting and Export Destination on Manufacturing Wages: Evidence for Sub-Saharan Africa

This paper investigates wage effects of trade status of African firms. Using data for manufacturing firms, we find a positive overall association between individual earnings and export status. Moreover, the skill wage premium in exporting firms is significantly higher. These results are consistent with either trade inducing higher wages in the exporting country, or with more productive (higher wage) firms self‐selecting into exporting. The results are not robust, however, to disaggregation by export destination. Exporting to outside Africa generates a negative wage premium whereas exporting to African markets yields a positive premium in export firms of the exporting country. This suggests that there is a disciplining effect on the wages of exporting firms only when exporting is to more competitive markets.     

Inequality,public good provision and the composition of trade

This paper investigates the effect of trade liberalization on the provision of public goods and shows that inequality also plays a vital role here. Public goods help enhance the productivity of firms, lower prices and raise profitability. The provision of public goods has different effects in closed and open economies. In an open economy, the impact of productive spending on increasing profit is stronger. Consequently, the opening up of the economy shifts the benefits of productive public goods from consumers to firms. As the median voters’, share of the firm’s profit rises, public goods become more appealing and flourish. Consequently, the manufacturing export is boosted by a rise in productivity.     

Learning‐by‐Exporting Revisited: The Role of Intensity and Persistence*

Two non‐mutually exclusive hypotheses can explain the empirically established export premium: self‐selection of more productive firms into export markets and learning‐by‐exporting. This paper focuses on how the temporal dimension of firms' exporting activities and the intensity of exports influence the scope of learning effects. Using a panel of Swedish firms and dynamic generalized method of moments estimation, we find a learning effect among persistent exporters with high export intensity, but not among temporary exporters or persistent exporters with low export intensity. For small firms, exports boost productivity among persistent exporters with both high and low export intensity, but the effect is stronger for persistent export‐intensive small firms.     

企业出口前研发投入、出口及生产率进步-来自中国制造业企业的证据

出口会导致企业生产率提高么?什么因素会影响出口的生产率效应?本文采用2001—2007年中国规模以上制造业企业调查数据估计了出口的即期和长期生产率效应。我们认为企业出口之前的研发投入可以通过增加企业的吸收能力来提高出口的生产率效应。通过采用倾向得分匹配的计量方法,我们发现:(1)平均看来,对于首次出口的企业,其出口当年企业生产率有2%的提升,然而在出口之后的几年中这种提升效应均不显著。(2)对于有出口前研发投入的企业,出口对生产率存在着持续且幅度较大的提升作用;但对于没有出口前研发投入的企业,出口对生产率没有显著的提升效应或提升效应短且较弱。(3)出口对生产率的提升效应随企业从事出口前研发年数的增加而提高。     

Productivity effects of international outsourcing: evidence from plant-level data

Abstract.  We investigate the impact of international outsourcing on productivity using plant-level data for Irish manufacturing. Specifically, we distinguish the effect of outsourcing of materials from services inputs. Moreover, we examine whether the impact on productivity is different for plants being more embedded in international markets through exporting or being part of a multinational. Our results show robust evidence for positive effects from outsourcing of services inputs for exporters, either domestic or foreign owned. By contrast, we find no statistically significant evidence of an impact of international outsourcing of services on productivity for firms not operating on the export market.

Why firms set different export prices? Evidence from Spain

Using firm-level export data for the 2010–2014 period, we investigate the variation of export prices across and within Spanish manufacturing firms. We find that more productive firms set higher export prices. However, this result is not robust to controlling for other firm-level characteristics and alternative productivity measures. We show that firms set higher export prices in more distant markets and in destinations with high GDP per capita, and lower export prices in large and low-competition markets. These latter results suggest that firms adjust the quality of their products to destination characteristics.
