International Trade,Offshoring and Heterogeneous Firms

Recent trade models determine the equilibrium distribution of firm‐level efficiency endogenously and show that freer trade shifts the distribution towards higher average productivity because of entry and exit of firms. These models ignore the possibility that freer trade also alters the firm‐size distribution via international firm migration (offshoring); firms must, by assumption, produce in their “birth nation.” We show that when firms are allowed to switch locations, new productivity effects arise. Freer trade induces the most efficient small‐nation firms to move to the large nation. The large country gets an “extra helping” of the most efficient firms while the small nation's firm‐size distribution is truncated on both ends. This reinforces the large‐nation productivity gain while reducing or even reversing the small‐nation productivity gain. The small nation is nevertheless better off allowing firm migration.     

信贷融资对异质性企业出口参与的影响* ——基于商业信贷和银行信贷角度的理论和实证分析

本文在新新贸易理论框架下，基于商业信贷和银行信贷的综合视角，系统研究了信贷融资对异质性企业出口参与的影响。本文重点围绕商业信贷对银行信贷的促进作用展开分析，从企业层面为中国出口增长“奇迹”提供来自金融视角的证据。本文在异质企业出口模型中引入商业信贷和银行信贷，论证商业信贷和银行信贷通过缓解出口成本融资约束影响企业出口参与，并运用中国制造业企业和IVprobit估计方法进行实证检验。本文发现：（1）改善商业信贷和银行信贷融资状况会提高企业出口概率；（2）商业信贷对银行信贷的促进作用有利于企业参与出口；（3）商业信贷对企业出口参与的作用不受企业所有制、企业规模、行业竞争性和企业出口固定成本差异的影响，银行信贷的作用则受上述差异的影响，商业信贷对银行信贷的促进作用受企业所有制和企业规模差异的影响。因此，发展信贷融资、建立商业信贷和银行信贷的互融互通机制，是加快中国出口增长的重要举措。     

Determinants of intra‐firm trade: Evidence from foreign affiliates in Sub‐Saharan Africa

By exploiting a unique sample of foreign affiliates in Sub‐Saharan Africa, we study previously examined and unexamined firm‐level determinants of intra‐firm trade. We document that foreign affiliates engaging in intra‐firm trade are relatively few and that the majority of these also engage in trade at arm's length, which accounts for an important fraction of their total trade. The identified firm‐level determinants of intra‐firm trade are consistent with property rights and intangible asset theories of the multinational firm, with international production hierarchy theories, as well as with theories of complex FDI and of multinational activity under credit constraints.     

Credit constraints and productivity of SMEs: Evidence from Canada

To what extent firms are constrained by external credit is usually unobserved in commonly used firm-level data. We use a survey of financing among Canadian small and medium-sized enterprises to measure the likelihood of a firm being constrained by credit. We find that firm size, current debt-to-asset ratio and cash flow are robust indicators of being financially constrained, while long-term debt to asset ratio is not a significant indicator of credit constraints. We then estimate the firm-level total factor productivity, taking into account the measured credit constraints. Omitting credit constraints leads to an upward bias of productivity estimates, by 4 percent. In addition, we find no strong evidence that suggests credit constraints lead to slower productivity growth. Finally, we confirm that both investment and employment growth are negatively affected by the measured credit constraints.     

Intra‐firm trade,exporting, importing,and firm performance

Abstract This paper examines firm heterogeneity in terms of size, wages, capital intensity, and productivity between domestic and foreign‐owned firms that engage in intra‐firm trade, firms that export and import, firms that import only, and firms that export only. As previously documented, heterogeneity between different groups of trading firms is substantial. Taking into account intra‐firm trade in addition to exporting and importing yields new insights into the productivity advantage previously established for exporting firms. The results presented here show that this premium accrues only to exporters that also import and to exporters that also engage in intra‐firm trade, but not to firms that export only. Using simultaneous quantile regressions, the paper illustrates that heterogeneity within different groups of trading firm is equally large. Some of this within‐group heterogeneity can be attributed to differences in trading partners.     

Does international openness affect the productivity of local firms?

This paper examines how international openness can change firm productivity in south‐eastern Europe (SEE), a crucial question for middle‐income countries. Using firm‐level data for six transition economies over the 1995–2002 period, we identify whether foreign ownership and propensity to trade with more advanced countries can bring about higher learning effects. We find that: (i) foreign ownership has helped restructure and enhance the productivity of local firms in four out of six countries; (ii) exporting to advanced markets has a larger impact on productivity growth in four countries, especially when the firm's absorptive capacity is taken into account; (iii) in contrast, exporting to the less competitive markets of the former Yugoslavia seems to negatively affect productivity growth in three countries; and (iv) learning effects from importing are similar to those from exporting. Our results suggest that trade liberalization is not uniformly beneficial. Regional composition of trade flows and absorptive capacity of local firms matter. Thus, trade liberalization within the SEE region may not provide a substitute for a general trade liberalization which includes access to the more competitive markets of countries belonging to the Organization for Economic Co‐operation and Development.     

Trade Liberalization and Heterogeneous Technology Investments

We propose a trade model where heterogeneous firms decide on a productivity‐enhancing technology investment. The model analyzes the impact of multilateral trade liberalization on firm‐ and industry‐level productivity. Freer trade increases the incentives to invest in technology by raising export profits. It also dampens these incentives, however, as profits stemming from domestic sales are reduced. Only exporters benefit from the former positive effect. The shape of the distribution of efficiency draws, the level of trade costs and the technology intensity of the industry are key elements removing the ambiguities regarding the net impact of trade liberalization.     

Second thoughts on the exporter productivity premium

Abstract Contrary to the prevailing interpretation, this paper shows that the central models of trade with heterogeneous firms ( Melitz 2003 ; Bernard et al. 2003 ) exhibit ambiguous predictions for the exporter productivity premium. This prospect arises because of differences between theoretical and empirical representations of firm productivity. Instead of marginal productivity, we examine in both models the theoretical equivalent of empirically observable productivity (value‐added per employee). Given the presence of fixed export costs or heterogeneous mark‐ups and trade costs, the observable productivity of exporters in proximity to the export‐indifferent firm turns out to be lower than that of non‐exporters; that is, the productivity distributions overlap. The paper reviews empirical literature that reports non‐positive exporter productivity premia in firm‐level data and discusses implications for empirical research on exporter performance, including learning and the role of non‐parametric regressions (stochastic dominance, quantile regressions), fixed costs, and productivity distributions.     

Firm heterogeneity,credit constraints,and endogenous growth

This paper is in general concerned with the role of firm heterogeneity for economic growth. We focus on heterogeneous productivity in innovation and credit constraints of firms within a semi-endogenous growth model reflecting recent empirical findings on firm heterogeneity. Our model allows for an explicit solution for transitional growth and for the balanced growth path level of innovations or ideas. The model predicts an optimal degree of heterogeneity in the presence of an endogenous firm distribution. This enables us to draw inference about the impact of key policy parameters of the model on these quantities and to draw conclusions about firm and capital market related policies.     

Disentangling barriers to internationalization

Abstract. Recent literature on multinational firms has focused on low productivity as a barrier to the internationalization of firms. But labour market frictions or financial constraints may also hamper internationalization. In order to assess the importance of these barriers, we present new empirical evidence on the extensive and intensive margin of exports and foreign direct investment (FDI) based on micro‐level data of German firms. First, we find a positive impact of firm size and productivity on firms’ international activities. Second, labour market frictions can constitute barriers to foreign activities. Third, self‐reported financial constraints have no impact on firms’ internationalization decisions. JEL classification: F23, G2     

Exports versus FDI in German Manufacturing: Firm Performance and Participation in International Markets

Recent theoretical work has been able to explain how even within narrowly defined industries, firms can exhibit heterogeneous degrees of participation in international commerce. Differences in productivity between firms are the principal explanation offered by theory to explain heterogeneity with respect to international commerce. In particular, theory predicts that the least productive firms will produce for the domestic market only, while better performers engage in export activities, and the top firms establish foreign subsidiaries. This paper presents an empirical test of the relationship between productivity and patterns of international trade and production. Using German firm‐level data from 1996 to 2002, we test the predicted rank ordering of productivity according to firms’ trade pattern by examining the distribution functions of the three subsets of firms for stochastic dominance. Our results are generally consistent with the predictions from theory, and document significant productivity differences according to trade patterns.     

Regional variations in exporters’ productivity premium: Theory and evidence

The international trade literature confirms that the average productivity of exporters is higher than that of nonexporters, while economic geography studies establish that urban firms tend to be more productive than rural ones. By introducing region‐specific transportation costs in a Melitz‐type heterogeneous‐firm trade model, the theory predicts that the minimum threshold productivity level for export is higher but that for survival by serving the local market is lower in the periphery region than in the core. Using Japanese plant‐level panel data, we find evidence supporting the theoretical prediction that exporters in the peripheral regions, especially those distant from the core, have large productivity premiums.     

Global sourcing and credit constraints

This paper incorporates credit constraints into a model of global sourcing and heterogeneous firms. Following Antràs and Helpman ( 2004 ), heterogeneous firms decide whether to outsource or integrate input suppliers. Financing of fixed organizational costs requires borrowing with credit constraints and collateral based on tangible assets. The party that controls intermediate inputs is responsible for these financing costs. Sectors differ in their reliance on external finance and countries vary in their financial development. The model predicts that increased financial development decreases the share of integration relative to outsourcing in a country. The effect is more pronounced in sectors with a high reliance on external finance. However, this effect is mitigated by higher productivity (TFP) and headquarter intensity. Empirical examination confirms the predictions of the model. An improvement in financial development from the 25th to the 75th percentile in industries at the 75th percentile in finance dependence relative to those at the 25th percentile is associated with a 16.8% decrease in the median share of US intra‐firm imports. An increase in TFP from the 25th to the 75th percentile in the TFP triple interactions increase the share of US intra‐firm imports at the median by 3.2%. An increase in headquarter intensity from the 25th to the 75th percentile in the headquarter intensity triple interactions increase the share of US intra‐firm imports at the median by 21%.     

Trade Liberalization and Productivity Growth

This paper presents a trade model with firm‐level productivity differences and R&D‐driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run.     

中国上市公司商业信用 周期性变化的宏观经济动因研究

本文为了揭示中国上市公司商业信用周期性变化的宏观经济动因,构建了一个宏观经济因素影响上市公司商业信用行为的理论分析框架,从宏观和微观两个层面分析了宏观经济发展状况、货币政策和通货膨胀水平对中国上市公司商业信用周期性变化的影响机理。利用中国上市公司季度面板数据进行了实证检验。结果显示,随着货币政策宽松、宏观经济扩张和通货膨胀水平的增加,中国上市公司提供的商业信用净额都显著降低。这些研究结果折射出,当货币政策收紧或宏观经济收缩时,商业信用资金从上市公司部门流向非上市企业部门;反之,当货币政策过度宽松或宏观经济过度扩张时,上市公司部门通过商业信用渠道从非上市企业部门吸纳商业信用资金。     

Bank loans vs. trade credit

Using a World Bank dataset of Chinese firms, we investigate the relative importance of bank loans and trade credit in promoting firm performance. To deal with possible endogeneity issues, we employ distinct and separable instrumental variables for bank loans and trade credit. We find that access to bank loans is central to improving firm performance and growth, while the availability of trade credit is much less important. Our results suggest that trade credit cannot effectively substitute for bank loans. Overall, our findings suggest the need for further development of China's formal financial institutions, which would enable the non‐state sector to grow much faster than it has grown in recent decades.     

Trade Liberalization and Firm Productivity: Evidence from Chinese Manufacturing Industries

This paper examines the impact of tariff reduction following China's World Trade Organization (WTO) entry on the productivity of Chinese manufacturing firms using a firm‐level panel database that comprises all of China's manufacturing firms with an annual turnover above 5 million yuan and that spans the period of 2000–2006. An instrumental variable estimator is used to account for the endogeneity of the tariff reduction. The results indicate that China's trade liberalization in the five years following its WTO entry has led to a 0.94% annual increase in total factor productivity for Chinese manufacturing firms. However, the overall productivity gain from the tariff reduction is a net result of a productivity depressing effect of output tariff reduction and a productivity enhancing effect of input tariff reduction. Both effects have diminished in magnitude over the years after China joined the WTO. Firm heterogeneity and turnover plays an important role in generating gains from trade liberalization. The surviving firms have managed to cope with and take advantage of lower tariffs. The extent to which the tariff reduction affects Chinese firms' productivity is also dependent on the ownership structure of the firms with foreign‐invested firms being the clear winner.     

Trade liberalization and credit constraints: Why opening up may fail to promote convergence

This paper examines credit constraints as one channel held responsible for hampering economic convergence between countries. Specifically, we extend a Melitz and Ottaviano ( 2008 ) type trade model with variable mark‐ups to allow for endogenous technology adoption. We consider a framework with two countries that potentially differ with respect to credit market development. Firms have the option to adopt a more efficient technology by paying some fixed cost that is more costly to finance for financially constrained firms. We find that technology adoption increases in both countries after trade liberalization but more so in the financially more developed country: the productivity gap widens. Simulations show that the welfare gap widens too. Opening up without sufficient access to external funding thus fails to promote convergence.     

Estimates of gender differences in firm’s access to credit in Sub-Saharan Africa

Based on firm level data from 16 Sub-Saharan African countries we show how three different measures of credit constraints lead to three different estimates of gender differences in manufacturing firms’ credit situation. Using a perception based credit constraint measure female owned firms appear relatively more constrained than male owned firms. Using formal financial access data we find no gender effect. Finally, using direct information on credit constraints, male owned small firms appear disadvantaged. Furthermore we show a strong size gradient in the gender gap for the two measures for which we find significant gender differences.     

Access to credit and informality among micro and small enterprises in Ethiopia

This paper examines the determinants of Micro and Small and Enterprises (MSEs) access to credit in Ethiopia using detailed firm‐level data collected in 2003. Its basic purpose is to identify the various attributes of a firm that determine its access to credit with an emphasis on the role of firm formality. We find that informal firms are more credit constrained compared to formal firms. A firm’s location, membership of a business association and maintaining an accounting record are found to be important determinants of access to credit. Further, we find firms whose owners have vocational training are more credit constrained than those who are not, as are firms that are exclusively male owned. There is no systematic relation between access to credit and a firm’s age, size and the sector in which it operates. The paper concludes with possible policy interventions designed to improve access to credit for MSEs in Ethiopia.
