Firm-level interactions between exporting and productivity: Industry-specific evidence

This paper investigates interactions between exporting and productivity at the firm level, using a panel of firms in the UK chemical industry. This is both highly technology intensive and the UK’s largest exporting sector. We find exporters are more productive than non-exporters, but are also on average smaller. This superior productivity performance among exporters appears to be caused by both self-selection and learning-by-exporting effects. In contrast to other studies, we find learning effects are significantly positive among new entrants, weaker for more experienced exporters and negative for established exporters. JEL no.

Industry Differences in the Effect of Export Market Entry: Learning by Exporting?

An extensive evidence base affirms the importance of sunk costs and firm heterogeneity to exporting. Only higher productivity firms can profitably cover sunk costs and enter export markets. This is the standard explanation for the regularity with which econometric analyses report that exporters are more productive than non-exporters. But what happens to their productivity trajectory once they have entered? Some theory points to the possibility of a further productivity boost, attributable to the effects of learning and competition. We investigate whether this is because the potential for a post-entry boost depends upon how exposed to competition the firm is. We find that industry differences are an important marker for determining whether learning effects boost productivity after export market entry.     

Does agglomeration promote internationalization of Chinese firms?

Knowledge spillover from the agglomeration of exporters can reduce the initial costs of exporting faced by other firms and thereby facilitate exports. We use a large dataset of Chinese manufacturing firms to assess whether industrial agglomeration lowers the minimum productivity level required for exporting and whether it increases a firm's probability of exporting. Semi-parametric quantile regressions reveal that the productivity advantage of exporters against non-exporters is markedly smaller in agglomerated regions. Furthermore, a parametric estimation of an export entry model indicates that the agglomeration of incumbent exporters contributes significantly to export participation, although its magnitude is limited. These spillover effects are generated not only by the agglomeration of exporting foreign invested firms (FIFs), but also, more importantly, by that of indigenous Chinese exporters. In fact, the agglomeration of exporting FIFs only contributes to the export entry of FIFs.     

Exports and success in German manufacturing

Exports and Success in German Manufacturing. - While Germany has a very open, export-oriented manufacturing sector, there has been little research on the role of exporting in German firms’ performance. This paper documents the significant differences between exporters and non-exporters and attempts to identify the sources of these disparities. Exporters are much larger, more capital-intensive, and more productive than non-exporters. However, the bulk of the evidence suggests that these performance characteristics predate the entry into export markets. The authors find no positive effects on employment, wage or productivity growth after entry. The authors’ results provide evidence that success leads to exporting rather than the reverse.     

Exporting May Not Always Boost Firm Productivity

A large empirical literature suggests the performance characteristics of firms that export are different from firms that do not. Specifically, exporters tend to be larger, more productive and pay higher wages than non-exporters. This paper reports on an econometric analysis of the characteristics of exporters and non-exporters in Swedish manufacturing industry. We use matching and difference-in-differences analysis to investigate a panel data set on a large number of firms and spanning almost 20 years. Some of our results echo those reported elsewhere. However, in contrast to the findings for every other country analysed so far, we find that the performance characteristics of exporters and non-exporters are remarkably similar. In particular, we find no evidence of pre- or post-entry differences in firm level productivity. This is a striking outcome, probably driven by the extremely high openness of the Swedish economy.

The exporter productivity premium along the productivity distribution: evidence from quantile regression with nonadditive firm fixed effects

A vast literature on the international activities of heterogeneous firms finds the existence of a positive exporter productivity premium. On average, exporting firms are more productive than firms that sell on the national market only. The Melitz (Econometrica 71:1695–1725, 2003) model, however, has implications for not only mean differences but also differences in the distribution of productivity. Furthermore, exporting firms may be different from non-exporting firms for reasons that are not included in the Melitz model. We believe that conditioning on firm fixed effects and studying the distribution of productivity are both necessary for empirical tests of the Melitz model. This paper is the first to employ a new quantile estimation technique for panel data introduced in Powell (Did the economic stimulus payments of 2008 reduce labor supply? Evidence from quantile panel data estimation. RAND Corporation Publications Department, Santa Monica, 2014). We find that the premium is positive at all productivity levels, but highest at the lowest quantiles. These results support theoretical models which suggest that there is a division in productivity between exporters and non-exporters.     

Export Performance and Destination Characteristics of Irish Manufacturing Industry

Recent research has sought to explore whether exporting enterprises have superior performance characteristics relative to non-exporters, and whether such superiority is associated with performance pre- and/or post-exporting. This paper extends existing research by examining the influence of export market destination on firm performance. It explores these issues using micro data on Irish manufacturing between 1991 and 1998, a time period during which Ireland experienced rapid export-driven growth. The study provides further evidence of the superior characteristics of exporters relative to non-exporters and supports the self-selection hypothesis that superior enterprises are more likely to export. We find export destination matters: the performance characteristics of enterprises that export globally differ from those that export locally. JEL no. F14     

Export activity and productivity: Evidence from the Taiwan electronics industry

Conclusions We use plant-level panel data for the Taiwanese electrical machinery and electronics industry to examine productivity differentials between exporters and non-exporters. Consistent with other recent literature, we find that exporters are larger, pay higher wages, undertake more investment expenditures in machinery, equipment, and new technology, and are substantially more productive than non-exporters.     

The U-Shaped Productivity Dynamics of French Exporters

We use data on French manufacturing firms to reveal that the productivity dynamics of new exporters is typically U-shaped. Prior to entry, firm productivity temporarily decreases, then recovers contemporaneously with entry, as the benefits from sales to foreign markets accrue. We show that the U-shaped pattern is more pronounced for intensively exporting firms and for firms operating in capital-intensive or high-technology sectors. This finding suggests that firms prepare to become exporters through prior specific investments and learning-to-export mechanisms. We then point to the limitations of studies that focus only on date of entry to exporting to discriminate between self-selection versus learning mechanisms. JEL no.  F10, F14, L60     

Exporting, capital investment and financial constraints

Many firms cite financial constraints as some of the most important impediments to their investment and growth. Using a unique data set from the Czech Republic this paper investigates the importance of financing constraints in the context of exporters. It finds that exporters are less financially constrained than non-exporters. However, after carefully correcting for possible endogeneity and selection issues, the evidence points to less constrained firms self-selecting into exporting rather than exporting alleviating firms’ financial constraints.     

Multinationals and plant survival

The aim of this paper is twofold: first, to investigate how different ownership structures affect plant survival, and second, to analyze how the presence of foreign multinational enterprises (MNEs) affects domestic plants’ survival. Using a unique and detailed data set on the Swedish manufacturing sector, I am able to separate plants into those owned by foreign MNEs, domestic MNEs, exporting non-MNEs, and purely domestic firms. In line with previous findings, the result, when conditioned on other factors affecting survival, shows that foreign MNE plants have lower survival rates than non-MNE plants. However, separating the non-MNEs into exporters and non-exporters, the result shows that foreign MNE plants have higher survival rates than non-exporting non-MNEs, while the survival rates of foreign MNE plants and exporting non-MNE plants do not seem to differ. Moreover, the simple non-parametric estimates show that domestic MNE plants are more likely to exit the market than other plants, also when controlling for plant-specific differences. Finally, foreign presence in the market seems to have had a negative impact on the survival rate of plants in non-exporting non-MNEs, but not to have affected plants in exporting non-MNEs or plants in domestic MNEs.     

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.

The ladder of internationalization modes: evidence from European firms

How do firms enter international markets? To answer this question, this paper uses a unique multi-country firm-level dataset which, besides direct exporting and FDI, provides explicit information on a number of internationalization modes: indirect exporting, outsourced manufacturing and service FDI. We present a theoretical framework in which modes requiring higher and higher commitment have progressively higher fixed and lower marginal costs. By estimating multinomial and ordered logit models, we present evidence in line with such a sorting framework with respect to TFP and innovativeness. We identify three ’clusters’ of modes: indirect exporters are similar to non-exporters, direct exporters and outsourced manufacturers constitute a second cluster while service and manufacturing FDI are the most demanding internationalization modes.     

Exports and Productivity Growth: First Evidence from a Continuous Treatment Approach

A recent survey of 54 micro-econometric studies reveals that exporting firms are more productive than non-exporters. However, previous empirical studies show that exporting does not necessarily improve productivity. One possible reason for this result is that most previous studies are restricted to analysing the relationship between a firm’s export status and the growth of its labour productivity, using the firms’ export status as a binary treatment variable and comparing the performance of exporting and non-exporting firms. In this paper, we apply the newly developed generalised propensity score (GPS) methodology that allows for continuous treatment, that is, different levels of the firms’ export activities. Using the GPS method and a large panel data set for German manufacturing firms, we estimate the relationship between a firm’s export-sales ratio and its labour productivity growth rate. We find that there is a causal effect of firms’ export activities on labour productivity growth. However, exporting improves labour productivity growth only within a sub-interval of the range of firms’ export-sales ratios. JEL no.  F14, F23, L60     

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.     

Learning-by-Exporting: Continuous Productivity Improvements or Capacity Utilization Effects? Evidence from Slovenian Firms

Following along the lines of a growing literature on the causal link between exporting and productivity, this paper analyzes the existence of “learning-by-exporting” using firm-level data for Slovenian manufacturing enterprises between 1994 and 2002. We fail to find conclusive evidence of learning-by-exporting. By matching new exporting firms to “sufficiently” similar non-exporters and using the difference-in-differences method on the matched pairs it is revealed that productivity improvements, although present, are far from permanent and tend to dissipate shortly after initial entry. Confronting the data on factor accumulation with TFP measures indicates that the perceived learning effects may in fact only be a consequence of increased capacity utilization brought about by the opening of an additional market.

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.     

Exports versus FDI: An Empirical Test

In a recent paper Helpman, Melitz and Yeaple argue firm heterogeneity leads to self-selection in the structure of international commerce. Only the most productive firms find it profitable to meet the higher costs associated with FDI; the next set of firms finds it profitable to serve foreign markets through exporting; while the least productive firms serve only the domestic market. The paper tests this assumption using the concept of stochastic dominance. Robust support is found for the model, the productivity distribution of multinational firms is found to dominate that of export firms, which in turn dominates that of non-exporters. JEL no.
