Firm strategies in expanding and diversifying exports

This paper provides novel empirical evidence on the patterns and dynamics of exports by Irish firms over the past two decades from a highly detailed data set of export records at the firm‐product‐destination level. We identify patterns of export concentration and specialisation and how these evolved over time. Firms’ strategies for export growth along product and destination markets mixes are then examined and the contributions of intensive (average sales) and extensive (number of products or markets) margins to overall exports and to export growth are calculated. We find that most exporting firms are quite small, selling a few products to a small number of destinations while export values are dominated by a relatively small group of highly globalised large firms selling many products to many destinations. Continuing exporters frequently introduce new products, drop products and enter and exit markets. Export growth in the case of Irish‐owned exporters appears largely driven by the extensive margin of product and destination changes. However, the opposite pattern holds for foreign‐owned firms with growth mainly coming from the intensive margin.     

出口成本、信贷约束与企业出口

出口固定成本的存在将导致企业生产率的“自我选择”效应。如果存在出口信贷约束,信贷获取能力强的企业出口表现将优于信贷获取能力差的企业。本文利用世界银行调查数据,实证发现信贷约束限制企业出口,银行营运资金贷款和固定投资贷款对企业出口的影响存在非对称性。营运资金贷款对扩大出口集约边际和扩展边际的作用都很明显,而固定投资贷款仅仅扩大出口扩展边际。此外,对于财务脆弱的企业,银行信贷的出口促进作用更加显著。     

The effect of the Uruguay round on the intensive and extensive margins of trade

Do tariffs inhibit trade flows by limiting the entry of exporters (‘firm extensive margin’) or by restricting the average volume exported by each firm (‘firm intensive margin’)? Using a gravity equation approach, we analyze how the decrease in tariffs promoted during the 90s by the Uruguay Round multilateral trade agreement affected the trade margins of French firms for 57 sectors and 147 countries from 1993 to 2002. Our main contribution is to estimate the elasticity of trade on both margins, controlling for the unobserved heterogeneity of trade flows thanks to a three-dimensional panel and to time-varying tariffs as a measure of variable trade costs. Our results show that the number of firms exporting in a given sector to a given destination is related to the level of tariffs. But they also show that the decrease in tariffs induced by the implementation of the Uruguay Round did not lead more firms to export and that it only induced incumbent exporters to increase their shipments. We control for two problems that may affect our basic specification: tariff changes may be endogenous and zero flows are not included. Our results are confirmed — even when the extensive margin is significant, its magnitude is very small.     

The productivity payoff of information technology in multimarket SMEs

This paper examines the effects of information technology (IT) adoption on the productivity of multimarket small and medium-sized enterprises (SMEs). The main hypothesis is that IT usage increases efficiency to a higher degree in diversified and internationalized firms compared with single-market SMEs. This hypothesis is tested using a large sample of more than 2,000 Spanish SMEs. Overall, intensive use of IT in operations processes is found to be associated with substantial increases in productivity of firms following both related and unrelated diversification. Also, exporting firms with more intensive use of IT have higher productivity. These results are consistent with previous theoretical arguments on the relationship between IT and efficiency of firms and open future research directions related to the role played by IT in the management control systems of both diversified and exporting firms.     

How Do Exporters React to Changes in Cost Competitiveness?

Various international institutions such as the European Commission, the ECB and the OECD often use unit labour costs as a measure of international competitiveness. The goal of this paper was to examine how well this measure is related to international export performance at the firm level. To this end, we use Belgian firm‐level data for the period 1999 to 2010 to analyse the impact of unit labour costs on exports. We find an estimated elasticity of the intensive margin of exports with respect to unit labour costs between −0.2 and −0.4. This elasticity varies between sectors and between firms, with more labour‐intensive firms having a higher elasticity. The microdata also enable us to analyse the impact of unit labour costs on the extensive margin. Our results show that higher unit labour costs reduce the probability of starting to export for non‐exporters and increase the probability of exporters stopping. While our results show that unit labour costs have an impact on the intensive margin and extensive margin of firm‐level exports, the effect is rather low, suggesting that pass‐through of costs into prices is limited. The latter is consistent with recent trade models emphasising that not only relative costs, but also demand factors such as quality and taste matter for explaining firm‐level exports.     

Firms and the global crisis: French exports in the turmoil

Global trade contracted quickly and severely during the global crisis. This paper uses a unique dataset of French firms to match export data to firm-level credit constraints and shows that most of the 2008–2009 trade collapse was due to the unprecedented demand shock and to product characteristics. While all firms have been affected by the crisis, the effect on large firms has been mainly at the intensive margin and has resulted in a smaller portfolio of products being offered to export destinations. The effect on smaller exporters has been to reduce the range of destinations served or to stop exporting altogether. Credit constraints have been an added aggravation for firms active in high financial dependence sectors. However, the share of credit constrained firms is small and their number has not increased hugely during the crisis, with the result that the overall impact of credit constraints on trade has been limited.     

The internationalization of new and small firms: A resource-based view

This paper seeks to enhance understanding of the internationalization of small- and medium-sized enterprises (SMEs). The study focuses upon the following issues: Can the characteristics of principal founders, businesses, and the external environment at one point in time be used to `explain' at a later date whether a firm is still an exporter or a nonexporter, whether exporting firms are larger in size than nonexporting firms, whether exporting firms report superior performance than nonexporting firms, and whether exporting firms are more likely to survive than nonexporting firms? To address these questions, this study draws upon a sample of 621 manufacturing, construction, and services businesses located in twelve contrasting environments in Great Britain surveyed first in 1990/91 and then re-interviewed in 1997.A resource-based view is reviewed to identify the range of factors encouraging some owner-managed SMEs to enter export markets. Four categories of human and financial capital are examined: general human capital resources, the principal founder's management know-how, the principal founder's specific industry know-how, and a principal founder's ability to obtain financial resources that can act as a buffer against random shocks. Variables relating to resource availability in the external environment were also collected and considered control variables. Previous studies have highlighted substantial industry differences in the propensity for businesses to enter export markets as well as to survive. The principal industrial activity of each business in 1990/91 was, therefore, considered a control variable.Variables collected during the 1990/91 survey were selected to explain variations in the propensity to export reported by surviving independent firms in 1997. After elimination of missing values, the working sample was reduced to 116 independent firms for this study (86 nonexporters and 30 exporters in 1997). In addition, the 21 variables were selected to explain variations in business size in 1997, profit performance relative to competitors reported in 1997, changes in employment over the 1990/91 to 1997 period, and business survival over the 1990/91 to 1997 period (213 survivors and 395 nonsurvivors).Multivariate statistical analysis confirmed that previous experience of selling goods or services abroad is a key influence encouraging firms to export. Businesses with older principal founders, with more resources, denser information and contact networks, and considerable management know-how are significantly more likely to be exporters. Further, businesses with principal founders that had considerable industry-specific knowledge are markedly more likely to be exporters. Businesses principally engaged in the service sectors and those located in urban areas are significantly less likely to be exporters.A key finding of this study is that the explanatory variables significantly associated with the propensity to export sales abroad are not the same as those significantly associated with selected size and performance measures. The resource-based explanatory variables selected fail to significantly detect employment-growing firms over the 1990/91 to 1997 period. They also fail to significantly distinguish surviving independent firms from nonsurviving firms.Results from this study will provide policy-makers and practitioners with additional insights into the key resource-based factors associated with the decision by new and small independent firms to export sales abroad. Practitioners and policy-makers can focus upon the characteristics of principal founders, businesses, and the external environment to predict the subsequent propensity of an independent firm to be an exporter. Policy-makers and practitioners who want more new and small firms to export outside their local areas may prefer to target their resources and assistance to the relatively smaller proportion of firms that have the business and principal founder profiles that are significantly associated with a firm being an exporter.     

Learning by exporting: Lessons from high-technology SMEs

We investigate the learning by exporting hypothesis by examining the effect of exporting on the subsequent innovation performance of a sample of high-technology SMEs based in the UK. We find evidence of learning by exporting, but the pattern of this effect is complex. Exporting helps high-tech SMEs innovate subsequently, but does not make them more innovation intensive. There is evidence that consistent exposure to export markets helps firms overcome the innovation hurdle, but that there is a positive scale effect of exposure to export markets which allows innovative firms to sell more of their new-to-market products on entering export markets. Service sector firms are able to reap the benefits of exposure to export markets at an earlier (entry) stage of the internationalization process than are manufacturing firms. Innovation-intensive firms exhibit a different pattern of entry to and exit from export markets from low-intensity innovators, and this is reflected in different effects of exporting.     

Export promotion activities in developing countries: What kind of trade do they promote?

Information problems involved in trading differentiated goods are a priori acuter than those associated with trading more homogeneous products. The impact of export promotion activities intending to address these problems can therefore be expected to differ across goods with different degree of differentiation. Empirical evidence on this respect is virtually inexistent. This article aims at filling this gap in the literature by providing estimates of the effect of these activities over firms trading different goods using highly disaggregated export data for the whole population of Costa Rican exporters over the period 2001–2006. We find that trade promotion actions favor an increase of exports along the extensive margin, in particular, in terms of destination countries, in the case of firms that are already selling differentiated goods. However, these actions do not seem to encourage exporter to start exporting these goods. Further, no significant impacts are observed for firms exporting reference-priced and homogeneous goods.     

Heterogeneous firms,exporter networks and the effect of distance on international trade

Distance effects in gravity equations are high and are not decreasing over time. Given that technical change in transport technology is biased in favor of long distances, this constitutes a challenge for existing theoretical models. In line with recent empirical evidence, this paper introduces a spillover effect from the number of exporters to the fixed costs of exporting into a trade model with heterogeneous firms. Since less firms export to remote markets, the equilibrium fixed costs are increasing in distance. This creates an additional effect of distance on aggregate trade flows: while the intensive margin of trade is unaffected, the extensive margin is magnified. This magnification leads to higher predicted distance effects. In addition, it offers a new perspective on non-decreasing distance effects: a relatively moderate strengthening of the spillover over time is sufficient to generate a constant distance elasticity.     

Does Export Openness Increase Firm‐level Output Volatility?

There is a widespread concern that increased trade may lead to increased instability and thus risk at the firm level. Greater export openness can indeed affect firm‐level volatility by changing the exposure and the reaction of firms to macroeconomic developments. The net effect is ambiguous from a theoretical point of view. This paper provides firm‐level evidence on the link between openness and volatility. Using comprehensive data on more than 21,000 German manufacturing firms for the period 1980–2001, we analyse the evolution of firm‐level output volatility and the link between volatility and export openness. Our paper has three main findings. First, firm‐level output volatility is significantly higher than the level of aggregate volatility, but it displays similar patterns. Second, increased export openness lowers firm‐level output volatility. This effect is primarily driven by variations along the extensive margin, i.e. by the distinction between exporters and non‐exporters. Variations along the intensive margin, i.e. the volume of exports, tend to have a dampening impact on volatility as well. Third, small firms are more volatile than large firms.     

Productivity and Learning‐by‐exporting: A Firm‐level Analysis of Indian Manufacturing

In this paper, we examine whether firms become productive by learning through exporting. To this end, we estimate the production function using microdata of Indian manufacturing firms operating in the period 1991–2001. In contrast to studies on developed countries, our results provide evidence that Indian manufacturing firms are experiencing a rise in productivity through entering export markets and thus experience the learning effect. We also find that there is a productivity rise prior to exporting. Therefore, our results also support the self‐selection mechanism for exporting.     

Where Do Firms Export,How Much and Why?

The empirical finding that exporting firms are more productive on average than non‐exporters has provoked a large theoretical literature based on models such as Melitz ( 2003 ), where more productive firms are more likely to overcome costs associated with trade. This paper investigates how closely the productivity heterogeneity framework fits the data from a firm‐level survey that includes information on export destinations and firm characteristics such as productivity. We find a high degree of unpredictable idiosyncratic participation in export markets by firms and a relatively weak positive correlation between the extent of a firm's export market participation and its export sales. We find that a small number of standard gravity variables provide a close fit to the country‐level determinants of trade but that greater variation results in more difficulty in explaining firm‐specific factors driving exporting behaviour. We also illustrate some elements of the dynamics over time in firm exporting patterns by destination. We show that lagged exporting activity has a significant effect on a firm's current exporting profile.     

Credit rationing and firm exports: Microeconomic evidence from small and medium‐sized enterprises in China

This paper examines the effect of credit rationing on export performance by small and medium‐sized firms in China. We use a detailed firm‐level data provided by the Small and Medium‐sized Enterprises Dynamic Survey (SMEDS) during 2015–16 to conduct this analysis. The SMEDS provides firm‐specific measures of credit rationing based directly on firm‐level responses to the survey rather than indirect ones, based on firm‐level financial statements. We find that, at the extensive margin, weak and strong credit rationing reduces export probability of small and medium‐sized enterprises (SMEs) by 15.1% and 39.6%, respectively. At the intensive margin, they decrease SMEs' export values by more than 20.0% and over 28.8%, respectively. Different than existing literature, we construct valid firm‐level instruments, firm‐level housing stock, for credit rationing rather than using province‐level instruments. We also employ county‐industry‐level instruments and obtain consistent estimates. In addition, credit rationing exhibits heterogeneous impacts on firms with different liquidity ratios, product portfolios, external collateral and capital utilisation rates.     

Modelling Small Firms' Decisions to Export – Evidence from Manufacturing Firms in Finland, 1995

In this paper, I model small firms' decisions to export by applying an existing model of the theory of diffusion of innovations and test the predictions of the model with data on Finnish SMEs. The model, incorporating so-called epidemic learning and rank effects, describes nicely the different phases of this decision-making process. The data used in the empirical analysis has been collected by interviewing directors of small industrial firms especially for this study. The results suggest, among other things, that the development of exporting in a small firm is particularly influenced by the language skills of the entrepreneurs, and that the smaller the firm, the faster is the adoption of the export strategy. In addition, the development of exporting has been faster in firms that have started exporting in the 1990s than in firms that began exporting before the '90s.     

Effectiveness of Export Support Programs: Impact on the Relational Capital and International Performance of Early Internationalizing Small Businesses

This article evaluates the impact of public export support programs on the internationalization of early internationalizing small businesses. We build and test a conceptual model of the link between export support services and early internationalizing firms’ relational capital and international performance in terms of both economic international performance and the number of foreign markets in which they are present. The results show that financial support is effective in enhancing firm performance only in terms of the number of foreign markets but not in terms of economic performance, that informational support is effective through its influence on relational capital, and that operational support is not. Our findings contrast with those of previous studies on firms that internationalize through stages and suggest that new export support services adapted to early internationalizing firms are needed.     

SME Networks and International Performance: Unveiling the Significance of Foreign Market Entry Mode

This study investigates the relevance of interorganizational networks for the international performance of small and medium‐sized enterprises (SMEs) in relation to the foreign market entry mode (FMEM) selected. We distinguish two groups of internationalized SMEs: exporting firms and micromultinational enterprises (mMNEs). Drawing on insights from the network theory, our study accounts for the role of intermediate outcomes (innovative behavior and foreign market knowledge). Structural equation modeling is conducted in a sample of U.K.‐based internationalized SMEs. Our findings suggest that interorganizational networks have an indirect influence on international performance but differences are found among the two groups of internationalized SMEs.     

Export Promotion: Bundled Services Work Better

Export promotion agencies provide exporters with a broad range of services, going from counselling to sponsoring their participation in international trade missions and fairs. These services may have heterogeneous effects and thus contribute differently to achieve the goals of these organisations. Empirical evidence on their relative effectiveness is rather limited. This paper aims at filling this gap in the literature. We compare the impact of different public trade promotion programmes on the extensive and intensive margin of firms’ exports, both to each other and with respect to no participation in these activities, by applying multiple treatment matching difference‐in‐differences on highly disaggregated export data for the whole population of Colombian exporters over the period 2003–06. We find that use of programmes that combine different services is associated with better export performance than their basic individual components, primarily along the country‐extensive margin.     

Indirect Exporters

Indirect exporters are defined as firms exporting through a trade intermediary. These firms have received rapidly expanding empirical and theoretical attention recently. I show that in Eastern Europe and Central Asia these firms do, as predicted by the theoretical literature, lie between domestic firms and direct exporters for a range of performance measures. Multi-product firms, despite their generally higher productivity, are shown to be more likely to use intermediaries than single-product firms, suggesting that “mixed exporting strategies” that use intermediaries are important for these firms. Analysis using a small panel subsample of the data suggests the sunk costs of indirect exporting are significantly lower than those for direct exporting, pointing to a role for intermediaries in “greasing the wheel” of entry to export markets.
