Spillovers through backward linkages and the export performance of business services. Evidence from a sample of Italian firms

We provide evidence on the role of spillovers through vertical linkages in service firms’ internationalisation process. We combine input–output coefficients with region-level information on downstream manufacturing sector exports to build a measure of spillovers through backward linkages, which we assess as a systematic determinant of Italian BS firms’ export status. Once considered firm and sector specificities, export spillovers especially matter for exporting to high-income economies outside Europe. This finding originates from higher sunk costs stemming from greater distance to the destination market and tougher competition within the destination market. Furthermore, the spillovers’ geographical scope is mainly local. We thus contribute to international business theory by generalising existing evidence from case studies on the importance of buyer–supplier relationships for service firms’ internationalisation across several BS sectors. Our research carries important implications for international business practices as well, as joining networks with internationalised customers may play an important role in enhancing BS firms’ exports, regardless of the BS supplied.     

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.     

Export Spillovers: Opening the Black Box

This paper studies the importance of export spillovers in a firm's decision to enter specific export markets and extends the current state of the literature by assessing different mechanisms through which they may occur, namely (i) labour movement, (ii) intra‐industry spillovers and (iii) inter‐industry linkages. We do so by exploiting a unique data set covering the universe of manufacturing firms in Denmark for the period 1995–2006 which combines transaction‐level export data, firm accounting data, employer–employee linked data and information from yearly input–output tables. We corroborate the literature on export spillovers by presenting robust evidence of destination‐specific export spillovers. The results suggest that labour mobility as well as intra‐ and inter‐industry linkages (backward linkages) are important channels for export spillovers, while presenting heterogeneous effects across firms of different size and export markets.     

Learning from exporting: The moderating effect of technological capabilities

There is evidence that exporters are more productive than non-exporters. Scholars argue that exporters may have access to knowledge spillovers in foreign markets and use this knowledge to become more efficient. However, we know little about whether learning from exporting is affected by firms’ heterogeneous resource endowments and, particularly, about the specific firm characteristics that matter the most in this respect. Utilizing a sample of 1534 Spanish manufacturing firms from 1990 to 2002, we empirically analyze whether a firm's technological capabilities (proxied by its relative R&D expenditures) affect its ability to learn from the interaction with foreign agents. We find that firm productivity increases after exporting for all firms. However, ex post productivity improvements are larger for the more technologically advanced firms than they are for their less technologically advanced counterparts. Our results show that some firms stand to benefit more from exporting than others and hint at the importance of absorptive capacity for knowledge acquisition overseas.     

Implications of Firm Controllable Factors on Export Growth

The need to stimulate export activity of U.S. companies has motivated research on export behavior of firms. Based on the strategic export model, this study attempts to investigate firm controllable factors that stimulate export growth. A survey of 640 small and medium sized manufacturing firms engaged in exporting showed that having a high commitment to exporting, having a possitive attitude toward exporting by placing less importance on perceived barriers to exporting (or export growth), having a customized product adaptation policy and willingness to modify the product, and seeking outside export assistance contribute to export success measured by export growth. International market expansion strategy did not seem to be associate with export growth.     

Demand uncertainty: Exporting delays and exporting failures

This paper presents a model of trade that explains why firms wait to export and why many exporters fail. Firms face uncertain demands that are only realized after the firm enters the destination. The model retools the timing of the resolution of uncertainty found in models with heterogeneity of firm productivity. This retooling addresses several shortcomings. First, the imperfect correlation of demands reconciles the sales variation observed in and across destinations. Second, since demands for the firm's output are correlated across destinations, a firm can use previously realized demands to forecast unknown demands in untested destinations. The option to forecast demands causes firms to delay exporting in order to gather more information about foreign demand. Third, since uncertainty is resolved after entry, many firms enter a destination and then exit after learning that they cannot profit. This prediction reconciles the high rate of exit seen in the first years of exporting. Finally, when faced with multiple destinations to which they can export, many firms will choose to sequentially export in order to slowly learn more about its chances for success in untested markets.     

Does firm size matter in exporting and using FTA schemes?

In this paper, we empirically compare the role of firm size when exporting with that when using free trade agreement (FTA) schemes. We employ a unique survey providing detailed information on FTA use by Japanese affiliates in ASEAN, India, and Oceania. Our findings from the analysis on Japanese affiliates in ASEAN are as follows. First, firm size matters in both decisions on exporting and on using FTA schemes. In particular, firm size is more quantitatively important in decisions on FTA use than on exporting. Second, firms with experience in utilizing FTAs for exporting have an approximately 40% higher probability of using an FTA for exporting to a new country. Third, larger-sized firms use a larger number of FTA schemes.     

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.     

Export behaviour of SMEs in transition countries

Melitz’s dynamic model of export participation is the basis of our empirical specification that accounts for a wide range of internal and external factors affecting the export behaviour of small and medium-sized enterprises (SMEs) in Transition Countries (TCs). Using firm-level data, our estimates highlight the particular importance of the human and technology-related factors to the export behaviour of SMEs in TCs. Other important factors for SME exporting activities are productivity-enhancing spillovers from industry—especially vertical—linkages, firm size, ownership type, type of activity, the availability of external finance, networking through business associations, and market share. In addition, significant period and country differences are identified. This paper contributes to the transition literature by filling an important gap in the understanding of the SME internationalisation process and by identifying a comprehensive set of variables to explain firms’ export behaviour in TCs.     

Productivity Premia for German Manufacturing Firms Exporting to the Euro‐Area and Beyond: First Evidence from Robust Fixed Effects Estimations

This paper reports estimates of the productivity premium of German firms exporting to the Euro‐zone and beyond, controlling for unobserved time‐invariant firm‐specific effects. Furthermore, it tests for self‐selection of more productive firms into exporting beyond the Euro‐zone. The main contribution of the paper is to correct a serious flaw in hitherto published studies that ignore the potentially disastrous consequences of extreme observations, or outliers. The paper shows that estimates of the exporter productivity premium by destination are driven by a small share of outliers that comprises some five per cent of all firms. These outliers are identified by a recently developed highly robust estimator for models with fixed effects. Using a ‘clean’ sample without these outliers, the estimated productivity premium of firms that export to the Euro‐zone only is no longer statistically different from zero at a conventional error level, and the estimated premium of firms exporting beyond the Euro‐zone, too, over firms that serve the German market only is tiny. Furthermore, an ex‐ante differential that is statistically significant and large only shows up for enterprises that exported to the Euro‐zone already and start to export to countries outside the Euro‐zone. These conclusions differ considerably from those based on non‐robust standard regression analyses.     

How Small Is Too Small? Firm Size as a Barrier to Exporting from the United States

The purpose of this paper is ask whether there is a minimum size that firms must achieve to take advantage of the benefits of exporting from the United States. An analysis of 2,822 firms in 49 different industries in South Carolina, a rapidly growing export–driven state, was conducted to address this question. This paper builds on the contributions of previous research in the areas of small to medium–sized enterprises (SMEs) and export success and SMEs in the export development process. Analysis of manufacturing exports from South Carolina indicates that firm size serves as a necessary as well as a sufficient condition for export success among small manufacturing firms. Reasons for this are discussed, and implications for managers and policymakers are offered.     

Financial vulnerability and export dynamics

This paper examines the implication of financial shocks on firms’ export dynamics in developing economies. To address this question, we use the Exporter Dynamics Dataset, which contains new data on the microstructure of exports for 34 developing countries between 1997 and 2011, and investigate how exporter behaviour is affected by financial crises. We find that financial crises in both the origin and destination countries have a large negative effect on firm, product and destination dynamics, particularly in industries dependent on external finance. Financial crises make the costs of exporting more difficult to meet and in turn reduce firms’ ability to start exporting, introduce new products and sell to new destinations. We also find that the impact of financial crises is less pronounced in exporting countries with relatively more open capital accounts, suggesting that portfolio inflows may be a good substitute for underdeveloped domestic financial markets.     

Foreign Market Competition as a Determinant of Exporter Performance: Evidence from Slovenian Manufacturing Firms

Most studies on the link between exporting status and firm productivity find no evidence of learning‐by‐exporting, whereas self‐selection of more productive firms into exporting is most often confirmed. Furthermore, empirical tests of the learning‐by‐exporting hypothesis rarely rely on a specific learning mechanism and instead estimate very general tests of the effects of exporting on improvements of firm efficiency. Lack of explicit controls for specific learning mechanisms in turn biases the empirical estimates against finding the learning effects. Here I undertake a more targeted approach to learning‐by‐exporting by using data on Slovenian manufacturing enterprises between 1994 and 2002 to explore a specific channel for learning in the export markets. Using a variety of empirical tests, I show that competition in exporting markets serves as an added criterion in firm self‐selection as only the most productive and fastest growing firms choose to enter more competitive foreign markets. Once home‐market competition is explicitly controlled, a significant productivity adjustment effect of exporting firms in response to intensification of export market competition is revealed. Crucially, this provides tentative evidence of learning‐by‐exporting, which has so far been elusive in the relevant literature.     

The decision to export: Firm heterogeneity,sunk costs,and spatial concentration

Integrating perspectives of the Uppsala model of internationalization process, international new ventures and trade theories of heterogeneous firms, this paper develops a dynamic discrete-choice model of export decisions by a profit-maximizing firm. Empirical analyses based on a panel data set of Chinese firms show that sunk costs, productivity, firm size, foreign ownership, industry competition and spatial concentration are positively associated with the decision to export, while state ownership has a negative association with the probability of exporting. However, we find that the relationships are not always uniform and depend on firm-specific idiosyncrasies. The results show that foreign-invested firms and large firms (regardless of ownership) rely on productivity performance related advantages for expanding overseas, while domestic firms, especially small- and medium-sized enterprises, build competitive advantage by leveraging agglomeration economies and the associated spillovers. Our results highlight the role of firm heterogeneity, sunk costs and spatial concentration in shaping the export behavior of firms.     

Firm export dynamics and the geography of trade

Two recent trends in international economics have been an increased focus on the geography of trade (e.g. what factors determine where a country exports) and the emergence of new theoretical and empirical work examining exporting activity at the firm-level. However, data limitations have prevented much progress in combining these two areas, because very few countries provide firm-level data breaking down firm exports by their destination. This paper uses a unique survey of Irish exporting firms with information on over fifty destinations for a five-year period to fill some of the gaps in this empirical literature. In particular we investigate how well the predications of a model of exporting with firm heterogeneity fits with the patterns of this detailed data source. Amongst our findings are that firm productivity differences are a factor in explaining the number of export markets a firm has but the prediction of a hierarchy of markets could only be weakly upheld by the data. Firm involvement in individual export markets is found to be much more dynamic than export status. Entry and exit to markets is shown to be a quantifiably important component of overall export flows, with this factor becoming more important for less popular markets. The paper also shows how the patterns of entry and exit into export markets combine to determine the overall firm-level distribution of number of markets entered.     

Segmenting U.S. firms for export development

In attempting to aid firms in their exporting efforts, various segmentation approaches have been developed by government agencies and research groups. Each of these segmentation schemes aims at the identification of specific export needs within different groups of firms. The four major approaches suggested in the literature propose to differentiate firms into groups based on the level of international activities, managerial attitudes, size, and service orientation of firms. The research presented in this article investigates these four segmentation approaches by applying them to common data collected from small and medium sized U.S. manufacturing firms and investigating their effectiveness in differentiating among groups of firms. The results indicate that the differentiation of firms according to their level of international activities is the most effective one of the four approaches investigated. Subsequently, various specific needs of exporting firms are presented and a redirection of current export promotion efforts is suggested.     

Geography,knowledge spillovers and small firms’ exports: an empirical examination for The Netherlands

This study examines the impact of external and internal scale economies on the decision to start exporting and the level of exports of innovating firms. Based on new trade theory, increasing returns to scale—both internal and external scale economies—are considered an important source of comparative and competitive advantage. The empirical analysis of (small) innovating firms in The Netherlands leads to two main findings. First, firms that are located in technical Marshallian clusters seem less inclined to become exporters. Availability of technical knowledge alone does not help to reduce entry costs that come with the decision to export and/or marketing and sales costs in order to achieve a higher export performance. Second, firms that experience difficulties in appropriating innovation rents due to labour poaching also seem to be less inclined to become exporters. The explanation for this second finding is the importance of outgoing knowledge spillovers, which is particularly relevant for small, product innovating firms. This reduces their probability to export. However, if firms export, the knowledge leaking argument is not valid for the export performance of the firm.     

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.     

A model of demand,productivity and foreign location decision among Taiwanese firms

We develop a theoretical framework to examine the relative importance of firm demand and productivity in firm decisions to export and where to locate foreign direct investments. The model shows that the equilibrium firm decision depends on product technology, consumer preference for product quality, fixed investment costs of establishing a foreign subsidiary, transportation costs and relative wages. Our empirical results confirm the predictions of the theoretical model. Firm-level demand and productivity components are important in explaining the decision to participate in foreign markets with their relative importance depending on the firm's organizational form (exports versus FDI) and the destination of the investments. In general, FDI firms are more productive than exporting firms regardless of FDI destinations. FDI firms also have a higher demand component than exporters and this demand component is stronger than productivity. Finally, among FDI firms, while those with a high demand index and productivity have a significantly higher propensity to invest in high-income countries, firm productivity is the sole determinant of firms undertaking FDI in low-income countries.     

Knowledge spillovers and high-impact growth: Comparing local and foreign firms in the UK

This paper is concerned with entrepreneurial high-impact firms, which are firms that generate ‘both’ disproportionate levels of employment and sales growth, and have high levels of innovative activity. It investigates differences in the influence of knowledge spillovers on high-impact growth between foreign and local firms in the UK. The study is based on an analysis of data from UK Innovation Scoreboard on 865 firms, which were divided into ‘high-impact firms’ (defined as those achieving positive growth in both sales and employment) and low-impact firms (negative or no growth in sales or employment). More precisely, the paper investigates the influence of knowledge spillovers on high-impact growth of foreign and local firms, from regional, sectoral and firm size perspectives. The findings suggest that (1) firms’ access to regional knowledge spillovers (from businesses and higher education institutions) is more significantly associated with high-impact growth of local firms in comparison to foreign firms; (2) because knowledge spillovers are more likely to occur in high-tech sectors (compared to low-tech sectors), firms in high-tech sectors are more associated with high-impact growth. Nonetheless, the relationship is stronger for local firms compared to foreign firms; (3) because small firms have greater need for knowledge spillovers (relative to large firms), there is a negative relationship between firm size and high-impact growth, but the negative relationship is greater for UK firms in comparison to foreign firms. Implications are drawn for policy and research.
