Trading firms in the services sectors: comparable evidence from four EU countries

We establish a set of stylised facts for trade and trading firms in five market services sectors using comparable firm- and activity-level data from four EU countries. Our analysis shows that exports account for much lower shares of overall sales in the services sectors than in manufacturing. This is because fewer firms are engaged in trade in the services sectors and also because within particular sectors firms trade a lower share of their sales on average. Services producers trade mostly goods, but in terms of value, trade in services is much more important to them than to manufacturers. Larger and more productive firms are more likely to be two-way traders and to engage in both goods and services trade. Trade by services firms is somewhat less dominated by firms that both export and import than trade by manufacturing firms. Few firms export many services or to many countries. The value of services exports is increasing in the number of markets served but not necessarily in the number of services traded.     

Importing,exporting and performance in sub-Saharan African manufacturing firms

This paper examines productivity differences between internationally trading and non-trading firms using data on a sample of firms from 19 sub-Saharan African countries. The paper provides the first evidence of whether exporters, importers and two-way traders perform better than non-traders, and whether there are differences in performance between different types of trading firms in sub-Saharan Africa. Our results indicate that exporters, importers and two-way traders perform better than non-exporters, non-importers and non-two-way traders. We further find that two-way traders perform better than importers only or exporters only, results largely consistent with recent results for other countries and regions. Considering information on export starters, continuers and exiters we also present some evidence suggesting that there is no significant difference in performance between export continuers and starters.     

Economic performance and international trade engagement: the case of Portuguese manufacturing firms

By combining economic and financial data for Portuguese manufacturing firms with data on their exports and imports, we uncover some aspects of the relationship between international trade engagement and firms’ performances. In line with recent theoretical and empirical developments in the international trade literature: (i) we testify that Portuguese international trade is highly concentrated, especially on the import side, and both in inter- and intra-sector terms; (ii) we corroborate previous studies and theses according to which two-way traders outperform only importers, only exporters and above all domestic firms; (iii) we find that the greater the diversification of markets and goods (especially with regard to imports), the better the performance achieved by internationalised firms; (iv) we notice that the higher the intensity of firms’ international trade (especially imports), the better their performance; (v) we also present evidence that destination markets for exports and origin markets for imports are also important in explaining firm’s performance.     

Higher productivity in importing German manufacturing firms: self-selection, learning from importing, or both?

This paper uses a newly available comprehensive panel data set for manufacturing enterprises from 2001 to 2005 to document the first empirical results on the relationship between imports and productivity for Germany, a leading actor on the world market for goods. Furthermore, for the first time the direction of causality in this relationship is investigated systematically by testing for self-selection of more productive firms into importing, and for productivity-enhancing effects of imports (‘learning-by-importing’). We find a positive link between importing and productivity. From an empirical model with fixed enterprise effects that controls for firm size, industry, and unobservable firm heterogeneity we see that the premia for trading internationally are about the same in West and East Germany. Compared to firms that do not trade at all two-way traders do have the highest premia, followed by firms that only export, while firms that only import have the smallest estimated premia. We find evidence for a positive impact of productivity on importing, pointing to self-selection of more productive enterprises into imports, but no clear evidence for the effect of importing on productivity due to learning-by-importing.     

Allocative Efficiency of Agrifood Traders: Shrimp Traders in Indonesia

Shrimp is one of Indonesia's most important agricultural export commodities, with an annual export value exceeding $1 billion. If this high-value sector is to remain competitive and continue to grow, rural traders must be able to efficiently allocate scarce labour and factor inputs to trade shrimp. This study tests for factors leading to allocative inefficiency in the shrimp trade, by estimating a stochastic cost frontier on the basis of data from a survey of 200 shrimp traders in Central Java and South Sulawesi. Our results show that larger firms have a distinct cost advantage in trade and, owing in part to greater access to factor markets, are more efficient in allocating factors. Small firms can improve their allocative efficiency and become more competitive by specialising in trading one shrimp variety and by using output contracts to mitigate risk in the output market.     

Effects of presidents’ characteristics on internationalization of small and medium firms in Japan

Recent heterogeneous-firm models of international trade suggest that productivity determines whether firms engage in export activity and foreign direct investment. In practice, however, many productive firms are not internationalized, whereas many unproductive firms are, which suggests that there are factors other than productivity that influence firms’ internationalization. This study uses a unique panel data set for Japanese small and medium enterprises (SMEs) to examine whether the personal characteristics of a firm’s president are factors in firm internationalization. We find that SMEs with a risk-tolerant, forward-looking president are more likely to be internationalized. These effects are large in magnitude, as is the productivity effect, which provides a partial explanation as to why many productive firms are not internationalized. In addition, we find that productivity has an insignificant effect on firms exiting export markets, whereas presidential myopia increases the probability of exit. The evidence further suggests that a firm’s initial export costs become sunk following its entry into export markets, which explains why many unproductive firms are internationalized.     

Shipment frequency of exporters and demand uncertainty

This paper examines how exporting firms adapt to the uncertainty stemming from demand volatility. By using monthly customs data from France, we decompose exports into different extensive and intensive margins including two novel margins: the number of months the firms exported (frequency) and the average export value per month. We establish four empirical patterns. First, firms export less to markets with higher demand volatility. Second, this effect is mainly explained by the frequency margin. Third, volatility affects the frequency margin through two channels: indirectly through lower trade volume and directly through logistics re-optimization. In particular, our results suggest that firms send less frequent, larger shipments to more uncertain markets conditional on total exports. Fourth, the effect of demand volatility is magnified on markets with longer time-to-ship. We propose that these observations are in line with simple stochastic inventory management approaches.     

Global production networks and China's processing trade

This paper unveils a systematic pattern in China's processing trade. In a cross-section of Chinese provinces, the average distance traveled by processing imports (import distance) is negatively correlated to the average distance traveled by processing exports (export distance). To explain this pattern, we set up a three-country industry-equilibrium model in which heterogeneous firms from two advanced countries, East and West, sell their products in each other's markets. Each firm can use two modes to serve the foreign market. It can directly export its products from its home country. Alternatively, it can indirectly export to the foreign market by assembling its product in a third low-cost country, China, which is located in the vicinity of East. Our model establishes two theoretical predictions relating China's geographical location to its processing trade patterns. First, China's processing exports are negatively affected by both an increase in import distance and a rise in export distance. Second, China's processing exports to East Asian countries are more sensitive to export distance and less sensitive to import distance than its processing exports to non-Asian countries. We find empirical support for both predictions.     

Wholesalers,indirect exports,geography, and economies of scope: Evidence from firm transaction data in Japan

This study examines wholesalers’ roles in manufacturers’ exports in Japan. First, it is shown that, like in the case of manufacturing sector, a productivity sorting on the overseas activities is also present in the case of wholesalers. Namely, only the most productive wholesaler firms can engage in foreign direct investment, and the next productive wholesaler firms can participate in export activities, and the least productive wholesaler firms do domestic transactions only. Second, we investigate how the wholesalers facilitate manufacturers’ export activities in the form of indirect exports. We have found that the wholesalers through which manufacturing firms indirectly export their goods are predominantly located in Tokyo or Osaka. The probability of indirect exports is negatively correlated with distance between manufacturers and wholesalers, but there are certain threshold distances at 300–500 kilometers, over which the chance of indirect exports turns null. Another notable finding is that wholesalers’ productivities have positive correlation with the chances of indirect exports whereas manufacturers’ productivities do not matter. The number of manufacturers from which a wholesaler purchases goods, is found to have a positive correlation with the probability of indirect exports, a type of economies of scope effect.     

The effect of tariff reductions on firm size and firm turnover in canadian manufacturing

Using panel data on 81 Canadian manufacturing industries over the 1983–1996 period, the authors show that the estimated impact of recent tariff cuts was a positive and significant increase in the exit rate of firms. Supplementing this finding with recent research showing, that exiting firms tend to be less productive than those that survive, this provides support for recent trade models asserting that increased exposure to international trade induces the exit of least efficient firms, thereby contributing to productivity growth.

Trade and employment in Vietnam: how firms' trade matters

This paper aims to analyse how employment and wages change when a firm's trade status is altered. Using a detailed firm-level dataset of Vietnamese manufacturing enterprises, the study finds that how firms trade matters for firm employment and wages in Vietnam. The average effect of one-way trading (exporting or importing) is positive for both firms' total employment and female employment. Direct trading activities are associated with a higher level of employment than indirect trading activities by firms. The female employment effect of direct exports is nearly three times higher than direct imports. Indirect imports hurt firms' total employment and female employment. Both direct and indirect two-way traders experience higher growth in firm employment than direct-only traders. However, it is interesting to note that indirect two-way trading activities have a positive impact on female employment. Furthermore, the commencement of direct import is also associated with greater labour cost advantage.     

Fixed Export Costs and Export Behavior

This article provides a direct assessment of how fixed export costs (FECs) and productivity jointly determine firm‐level export behavior. Using Chilean data, we construct indices of FECs for each industry‐region‐year triplet and match them to domestic firms. Our empirical results show that firms facing higher estimated FECs are less likely to export, while those with higher productivity export more. These outcomes are the foundation of the widely‐used sorting mechanism in trade models with firm heterogeneity. We also find that the substitution between FECs and productivity in determining export decisions is weaker for firms with higher productivity. Finally, among firms that export, both larger FECs and greater within‐triplet productivity dispersion are associated with a greater export volume of the average exporter.     

Exports and Productivity Selection Effects for Dutch Firms

The paper tests whether recent theories of international trade with heterogeneous firms can explain the export patterns in Dutch firm- and plant- level data in manufacturing and services. Recent trade models with heterogeneous firms predict that the export decision of firms is affected by sunk entry costs in foreign markets, with only the most productive firms self-selecting into exports. We test a latent variable model of the export decision by probit regressions and standard OLS panel regressions. Our results support the self-selection prediction. The process further appears to be conditioned by scale effects, market structure and multinational affiliation. Regarding alternative explanations, we do not find evidence for the learning-by-exporting hypothesis, even when controlling for the firm’s distance to the international productivity frontier.     

Upstreamness,exports, and wage inequality: Evidence from Chinese manufacturing data

In this paper we investigate within-firm wage inequality across heterogeneous industries that hold different positions in the domestic value chain, and across heterogeneous firms that have different exposure to trade. We find that the wage inequality problem is more severe in upstream industries than in downstream ones, and among firms with greater exposure to trade (i.e., larger export share of sales). Our findings support both classic and new new trade theories on wage inequality. In downstream industries where Chinese firms are typically engaged in processing and assembly work with intensive use of unskilled labor, trade leads to less wage inequality within firms. However, trade also introduces pro-competitive effects which usually benefit exporters and their skilled labor. The results hold after various checks and controls for robustness.     

金融危机与福建出口贸易发展的稳定性分析——基于福建和江苏的比较研究

入世以来,较之于江苏出口贸易的强劲发展势头,福建则表现出明显的增长乏力特征。在国际金融危机期间,相对于江苏而言,福建的出口贸易遭受冲击的程度相对小些。研究表明,在中国融入经济全球化程度逐步加深的今天,出口波动性小的地区的贸易发展并不意味着一定优于出口波动性大的。     

Understanding Cross-Country Differences in Exporter Premia: Comparable Evidence for 14 Countries

We use comparable micro level panel data for 14 countries and a set of identically specified empirical models to investigate the relationship between exports and productivity. Our overall results are in line with the big picture that is by now familiar from the literature: exporters are more productive than non-exporters when observed and unobserved heterogeneity is controlled for, and these exporter productivity premia tend to increase with the share of exports in total sales; there is evidence in favour of self-selection of more productive firms into export markets, but nearly no evidence in favour of the learning-by-exporting hypothesis. We document that the exporter premia differ considerably across countries in identically specified empirical models. In a meta-analysis of our results we find, consistent with theoretical predictions, that productivity premia are larger in countries with lower export participation rates, with more restrictive trade policies, lower per capita GDP, less effective government and worse regulatory quality, and in countries exporting to relatively more distant markets.

Higher wages in exporting firms: self-selection, export effect, or both? First evidence from linked employer-employee data

While it is a stylized fact that exporting firms pay higher wages than non-exporting firms, the direction of the link between exporting and wages is less clear. Using a rich set of German linked employer-employee panel data we follow over time plants that start to export. We show that the exporter wage premium does already exist in the years before firms start to export, and that it does not increase in the following years. Higher wages in exporting firms are thus due to self-selection of more productive, better paying firms into export markets; they are not caused by export activities.     

Assessing Productivity Gains from International Trade in a Small Open Economy

Empirical evidence suggests that exporter firms tend to charge higher markups than non-exporters due to trade barriers. The exporters’ markup premium, however, may disappear in a special case, namely when the home country is small relative to its trade partners and trade barriers are low. This can be because competition is more intense in the large export destination than in the small home country, so that firms are able to set higher markups for locally sold products but not for exports. This paper provides empirical evidence on the validity of this special case by estimating markups for firms in Luxembourg who generally export to larger countries. The estimated negative markup premium for exporters has important implications for the productivity measurement. In a sufficiently small open economy, exporters’ productivity may be biased downward, when the firm-level markup variation is not controlled for in the productivity estimation. The bias in the productivity estimates further leads to the inaccurate conclusion that openness to international trade lowers allocative efficiency.     

自由贸易抑或贸易保护——国际贸易的经济增长效应再考察

全球经济复苏过程中,发达国家与新兴经济体之间关于自由贸易的争议也变得空前激烈。国际贸易是否有利于全球经济增长?这实际上是长期以来国际经济学与发展经济学领域颇具争议的问题之一,而在当下对这一问题进行重新审视更具有重要的现实意义。传统贸易理论对贸易合理性的探究尽管触及了经济增长问题,但在贸易静态收益理论的框架下,国际贸易究竟是否会促进一国经济增长,既取决于各个国家在各个发展阶段的经济增长究竟偏向于出口部门还是进口部门,也取决于各种贸易政策对各个部门的相对供给和相对需求的影响。本文对现有针对国际贸易与经济增长关系所做的实证研究作了系统回顾和分析总结,明确指出了目前各种看似矛盾的实证证据背后的理论和技术根源。在此基础上,运用两阶段最小二乘估计(2SLS)和GMM动态面板回归技术,对1960～2006年期间全球各国面板数据进行分析,对不同收入水平的国家组别分别就其贸易占GDP比重与GDP增长之间的关系进行实证检验。文章发现,上述实证研究证明国际贸易对经济增长的促进作用与一国经济发展阶段相关,但对不同收入水平的国家而言则存在差异,同时进口和出口在经济增长中的表现也存在差异性。总体来看,对中等收入国家而言,贸易占GDP比重与GDP增速之间的关系最强,进出口均有较强带动作用;高收入国家贸易占GDP比重与GDP增速之间关系较弱,进口的作用甚至大于出口;低收入国家贸易占GDP比重与GDP增速之间的关系最弱,进口甚至有抑制作用。
