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.     

Exporting and Economic Performance: Firm‐level Evidence of Spanish Manufacturing

In a previous paper, Delgado, Fariñas and Ruano (2002) report TFP differences between exporters and non‐exporters on the basis of a sample of Spanish manufacturing firms. In this paper, we extend the previous analysis in three directions using a similar data set. First, we investigate additional economic performance differences between exporters and non‐exporters. Second, we measure TFP differences estimating production functions that control for unobserved heterogeneity and simultaneity bias. Third, we explore the self‐selection and learning‐by‐exporting hypothesis as explanations for the greater performance of exporters. With respect to the results, we confirm that many indicators of economic performance such as productivity, size, wages and innovation are greater in exporting firms. Furthermore, TFP differences between exporters and non‐exporters estimated with parametric methods are remarkably similar to those estimated using index numbers. Finally, performance differences and transition patterns between the export market and the domestic market indicate higher performance for entering exporters with respect to non‐exporters at the moment of entry. We find evidence of selection in the entry and the exit side of the export market. One of the basic results that we obtain indicates that after controlling for self‐selection, the productivity growth of entering exporters does not significantly change with respect to non‐exporters. As the evidence we find indicates no systematic changes in performance between non‐exporters and exporters after entry takes place, we do not confirm the learning‐by‐exporting hypothesis.     

Efficiency and Ownership Structure: The Case of Poland

We examine the effects of foreign entry on productive efficiency during the Polish investment liberalisation. The performance of foreign acquisitions is compared to foreign firms entering the market through greenfield entry, as well as domestic acquisitions of privatised firms, domestic greenfields and remaining state‐owned (non‐privatised) firms during the period 1995–2000. We find that foreign privatised firms have realised larger productivity gains than all types of domestic firms and that this is not due to higher price‐cost margins, which is consistent with the idea that foreign firms bring in firm‐specific knowledge. Foreign greenfields have the highest average labour productivity, while foreign privatisations show the largest productivity increase.     

Investment History and Market Orientation Effects in the TFP–FDI Relationship1

This paper examines the robustness of previous stochastic dominance tests that find significant total factor productivity (TFP) heterogeneity between firms that export abroad and multinational enterprises (MNEs). We extend this literature by focusing on how ‘within‐MNE’ heterogeneity affects the extent to which one can identify the TFP threshold in the exporter–MNE TFP relationship. Within‐MNE heterogeneity is established by determining both the number and location of the foreign affiliates established by each MNE. In this way, we separate single‐affiliate MNEs from those with multiple affiliates, as well as analyse the role played by vertical FDI, a topic typically ignored in previous stochastic dominance tests of the Helpman et al. (2004, American Economic Review, 94, 300–16) hypothesis. Our empirical tests employ Japanese firm‐level FDI and TFP data for the period 1975–2000. Using Kolmogorov–Smirnov tests to determine stochastic dominance, we find significant TFP heterogeneity within the MNE group based on investment history and affiliate geographic location. While our results confirm the standard HMY three‐tiered classification to exist for Japanese firms, exporter–MNE ‘between‐group’ TFP heterogeneity is sensitive to the ‘within‐MNE’ investment history heterogeneity. We note that single‐ and two‐affiliate MNEs are statistically more similar to exporting firms than to MNEs with greater foreign affiliate totals. This shows the exporter–MNE TFP threshold to be not as explicit as Helpman et al. (2004, American Economic Review, 94, 300–16) suggest. In fact, our results allow us to identify the MNE‐side width of Girma et al.’s (2005, Economic Letters, 83, 317–24) ‘uncertainty region’ surrounding this threshold. Finally, we also find a strong TFP–market orientation relationship exists where the most productive firms follow complex integration strategies, lesser TFP firms do horizontal FDI, and the least productive MNEs do vertical FDI.     

Exports and Productivity: A Survey of the Evidence from Firm‐level Data

While the role of exports in promoting growth in general, and productivity in particular, has been investigated empirically using aggregate data for countries and industries for a long time, only recently have comprehensive longitudinal data at the firm level been used to look at the extent and causes of productivity differentials between exporters and their counterparts which sell on the domestic market only. This paper surveys the empirical strategies applied, and the results produced, in 54 microeconometric studies with data from 34 countries that were published between 1995 and 2006. Details aside, exporters are found to be more productive than non‐exporters, and the more productive firms self‐select into export markets, while exporting does not necessarily improve productivity.     

Export Premium,Self‐selection and Learning‐by‐Exporting: Evidence from Chinese Matched Firms

This study empirically focuses on examining the hypotheses of export premium (exporters are more productive than non‐exporters), selection‐into‐exporting (more productive firms are ones that tend to become exporters) and learning‐by‐exporting (new export market entrants have higher productivity growth than non‐exporters in the post‐entry period). The propensity score matching method is used to adjust for observable differences of firm characteristics between exporters and non‐exporters, allowing an adequate ‘like‐for‐like’ comparison. We also use the difference‐in‐difference matching estimator to capture the magnitude of different productivity growth between matched new export market entrants and non‐exporters in the post‐entry period up to two years. Drawing on 2,340 Chinese firms in the period 2000–02, we find evidence for export premium and self‐selection, and once the firm has entered the export market there is additional productivity growth from the learning effect, in particular in the second year after entry.     

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.     

The Direct Contribution of FDI to Productivity Growth in Britain, 1997–2008

This paper considers the contribution of foreign‐owned plants and firms to aggregate total factor productivity (TFP) growth in Britain for 1997–2008 using data from the Annual Respondents' Database. The contribution of different sub‐groups is further decomposed to show the role of continuing plants vis‐à‐vis reallocations in output shares. TFP is calculated using system GMM estimation. Taking into account the smaller initial size of the foreign‐owned sector in 1997, foreign‐owned plants contributed relatively more to aggregate productivity growth than UK‐owned plants over the period. This strong performance is mostly the result of reallocations of output shares towards high productivity continuing plants and the opening of high productivity plants.     

Evaluating the Contribution of Exporting to UK Productivity Growth: Some Microeconomic Evidence

This study assesses the contribution of exporting activities to aggregate productivity growth in the UK for all market‐based sectors for the period 1996–2004, using a weighted FAME dataset. Based on decompositions of productivity growth, our findings suggest that, overall, exporting firms experience faster productivity growth than non‐exporting firms and therefore contribute more to national productivity growth. In addition, aggregate productivity for exporters benefits from a large contribution from ‘continuing’ firms improving their productivity, as well as exporters that have been taken‐over/merged or started‐up as new firms. In contrast, most of the TFP improvement for non‐exporters is attributable to lower productivity firms exiting, rather than from internal improvements or the productivity‐enhancing impact of new firms.     

Trade,Tariffs and Total Factor Productivity: The Case of Spanish Firms

The aim of this paper is to examine the sensitivity of total factor productivity (TFP) to foreign competition in the case of a European country. Using the Olley and Pakes method, we calculate the TFP of Spanish manufacturing firms and study the impact of EU tariffs and the presence of foreign products and imports on TFP at the firm level. Applying the System‐GMM method, we find that TFP is negatively impacted by European tariffs, whereas competition in the form of the increased presence of foreign products in the domestic market and firm imports leads to improvements in the TFP. Moreover, these two effects are complementary. We also find evidence of important asymmetries among firms depending on their involvement in foreign markets.     

Do exports generate higher productivity? Evidence from Slovenia

I use matched sampling techniques to analyze whether firms that start exporting become more productive, controlling for the self-selection into export markets. To this end, I use micro data of Slovenian manufacturing firms operating in the period 1994-2000. Overall I find that export entrants become more productive once they start exporting. The productivity gap between exporters and their domestic counterparts increases further over time. These results also hold at the industry level and are robust to other controls that may be associated with increased productivity, such as private ownership. Using information on the (firm-level) destination of exports, I find that the productivity gains are higher for firms exporting towards high income regions.     

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.     

Does Exporter Turnover Contribute to Aggregate Productivity Growth? Evidence from Malaysian Manufacturing

Malaysia’s economic success is to a significant extent underpinned by its export‐oriented manufacturing sector. The sector has a large foreign presence, with MNCs attracted by the open trade and investment regime, and FDI‐friendly policies. Using unpublished manufacturing census data for 2000 and 2005, we apply the methodology by Foster et al. (1998) to decompose productivity growth. The analysis shows that exporters were more productive than domestic‐oriented establishments, and were distinctly more competitive. The empirical evidence also shows that establishment turnover is important in boosting productivity growth. In particular, we find that turnover of exporters made a larger contribution to aggregate productivity growth compared with domestic‐oriented establishments during the period from 2000 to 2005. Surviving establishments (those that operated in both years), on the other hand, made a negative contribution. It is noteworthy that entrants to export markets were more productive than surviving non‐exporters and even surviving exporters. Exiters from export markets or ‘export failures’, on the other hand, were less productive than continuing exporters. Given the importance of turnover to productivity growth, the government should ensure unrestricted entry to the export sectors for both foreign and domestic investors. Continuing with pro‐FDI policies is also important, given the keener global competition.     

Intermediaries,Firm Heterogeneity and Exporting Behaviour

In this paper, we present one of the first work on the relation between firm productivity and exporting behaviour in the presence of intermediaries. Using a standard trade framework à la Melitz (2003, Econometrica, 71 , 6, 1695) and Chaney (2009, American Economic Review, 98, 4 , 1707), we find that the most productive firms have sales in the home country and also exporting directly to foreign countries, followed by firms with sales in the home country and exporting both directly and through intermediaries, by firms with sales in the home country and exporting through intermediaries, and finally by firms with sales in the home country only. These theoretical predictions are borne out in a data set of 12,679 firms in 29 developing economies during the 2002–06 period.     

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.     

A method for calculating export supply and import demand elasticities

This article has a dual aim. First, it sets out to underline a learning-by-exporting effect in Spanish firms between 1991 and 2002. It further seeks to outline the conditions allowing firms to benefit from these spillover effects. Using a propensity score matching method, a group of firms having entered the export market (treatment group) is compared with a similar group of non-exporting firms (control group), and difference-in-differences regressions are carried out. The results show a cumulative productivity differential of 32% for the first four years of exporting, with continuous improvement in productivity. After three years of exporting, productivity gain is still approximately 10%. This study shows that increases in capacity utilisation and competitive pressure from foreign markets are insufficient to explain this causal link between exporting and total factor productivity (TFP). It is thus possible to deduce the presence of a learning-by-exporting effect, benefiting firms with sufficiently qualified employees and which are already engaged in international relations (due to foreign suppliers and/or foreign equity participation).     

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.     

Internationalisation and Economic Performance of Enterprises: Evidence from Polish Firm‐level Data

This article provides evidence on the relative performance of internationalised firms using Polish firm‐level data, spanning the period 1996–2005 and covering all medium and large enterprises. We distinguish between three modes of internationalisation: foreign direct investment, exporting and importing of capital goods. Our results point strongly at the superior performance of foreign affiliates vs domestic firms, exporters vs non‐exporters, and importers vs non‐importers: internationalised firms are larger, more capital intensive, pay higher wages and are more productive than purely domestic firms. Foreign ownership is the strongest factor accounting for gains from internationalisation. The premia from exporting are substantially lower, though also significantly positive. The performance of capital goods importers is also higher compared to non‐importers and is to some extent related to their involvement in other types of international activity. The results are robust to the choice of specification and productivity estimator. The analysed enterprises recorded a sizeable and broad‐based productivity improvement over the period under consideration. Not only the initial levels of productivity of exporters, importers and foreign affiliates were on average significantly higher that those of their non‐internationalised counterparts, but they also recorded faster productivity gains (manifested in increasing productivity premia), so that the discrepancies grew even larger. We also perform the analysis of productivity spillovers from internationalised firms onto own, downstream and upstream sectors. We find evidence of significant horizontal and backward spillovers from all three types of international activity. Our results suggest that trade externalities are rather of a horizontal nature, while those related to foreign direct investment operate mainly via backward linkages.     

Trade shocks,product mix adjustment and productivity growth in Italian manufacturing

In this paper, we use firm-level data on the universe of Italian manufacturing multi-product exporters to test whether demand shocks in export markets lead multi-product exporters to increase their productivity. The main mechanism behind the documented productivity gains is the reallocation of resources across products within firms (American Economic Review, 104, 2014 and 495; National Bureau of Economic Research Working Paper Series No. 22433, 2016). Intuitively, the increased demand stemming from foreign markets will induce firms to adjust their product mix by moving inputs from low to high productive/profitable uses. We find that these productivity gains are significant and can explain between 1/10 and 1/2 of aggregate productivity growth in the manufacturing sector.
