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.     

Exporting and Environmental Performance: A Firm‐level Productivity Analysis

The objective of this paper is to study empirically the relationship between export orientation and firms’ environmental performance from different perspectives of trade theory. On the one hand, productivity heterogeneity is analysed within the new trade‐theoretical framework. The approach followed is to determine firm‐level productivity components, including an environmental productivity indicator (as a performance measure) and taking as reference the Spanish food industry. On the other hand, from the traditional comparative advantage perspective, this study also develops an export performance model to evaluate the effect of technology, environmental variables and factor endowment on exporting. The results show greater environmental productivity and corporate efficiency for export‐oriented firms. Our findings also determine the positive effect on firms’ export intensity of environmental performance as a factor of specialisation and technology proficiency.

Offshoring and Outsourcing Potentials: Evidence from German Micro‐Level Data

This paper provides two indicators that measure: (i) offshoring potentials (cross‐country geographical relocation) and (ii) outsourcing potentials (organisational relocation) separately at the level of jobs, occupations, tasks and industries. We use four waves of the BIBB/BAuA Labour Force Survey in Germany and apply principal component analysis based on a large set of potential determinants of offshoring and outsourcing derived from the literature. Our results show significant variation across these levels in the determinants of both dimensions. We provide a comprehensive empirical classification of the determinants of how easily jobs can be offshored and outsourced. This can serve as a basis for further research to investigate the economic effects of job offshoreability.     

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.     

State‐owned Enterprises,Exporting and Productivity in China: A Stochastic Dominance Approach

A popular explanation for China's rapid economic growth in recent years has been the dramatic increase in the number of private domestic‐ and foreign‐owned firms and a decline in the state‐owned sector. However, recent evidence suggests that China's state‐owned enterprises (SOEs) are in fact stronger than ever. In this paper, we examine over 78,000 manufacturing firms between 2002 and 2006 to investigate the relationship between ownership structure and the degree of firm‐level exposure to export markets and firm‐level productivity. Using a conditional stochastic dominance approach, we reveal that although our results largely adhere to prior expectations, the performance of SOEs differs markedly between those that export and those that supply the domestic market only. It appears that China's internationally focused SOEs have become formidable global competitors.     

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.     

Firm R&D,Absorptive Capacity and Learning by Exporting: Firm‐level Evidence from China

The absorptive capacity of firms developed through R&D promotes learning by exporting. In this paper, we estimate the instantaneous and long‐run productivity effects of exporting on the universe of Chinese manufacturing firms. We find that exporting has very different productivity effects for firms with different pre‐export R&D status. It has large and lasting productivity effects for firms with pre‐export R&D, while it has little effects for firms without pre‐export R&D. Furthermore, the effect of exporting increases with the number of years of pre‐export R&D investment.

External Debt,Labour Productivity Growth and Convergence: Evidence from Sub‐Saharan Africa

Sub‐Saharan Africa (SSA) has long suffered from lagging productivity and excessive levels of indebtedness. Using both parametric and non‐parametric techniques, this paper examines the impact of external debt on labour productivity growth and convergence across SSA economies over the period 1970–2010. The results indicate the presence of debt‐overhang effects, regardless of model and sample specification. Debt reduction through the Heavily Indebted Poor Countries and Multilateral Debt Relief initiatives enhanced growth but was not successful in offsetting the debt‐overhang effects. Moreover, excessive levels of external debt were responsible for divergence in output per worker over the early 1990s. Although this trend was reversed over the 2000s, reduction in debt through the debt relief initiatives seems to have been insufficient in helping heavily indebted countries in SSA catch up with the labour productivity levels of the best‐performing economies in the region.     

The Quest for Robust Counterfeit and Piracy Figures: Custom Agencies as Statistical Decision‐makers and Recent Evidence Based on German Imports

Based on unique custom seizure data, we extrapolate robust figures on the amount of counterfeit and piracy in German imports. We therefore outline a simple model which explores estimation biases in counterfeit statistics provided by utility‐maximising custom agencies. Our empirical strategy sets out to (i) provide evidence on bias and, (ii) guided by theory, identify an unbiased subsample of the data. Upper bound population estimates (counterfeit shares) for 2010–11 suggest that around 17 per cent of all German imports are counterfeit. In addition, we highlight differences in counterfeit trade by commodity and distribution channel, and conclude with policy advice.     

The Determinants of Firm Exit from Exporting: Evidence for the UK

This study seeks to understand to what extent new exporters are able to survive in international markets and whether exit from exporting is more likely to be associated with firm-level heterogeneity or more general factors such as trade costs and/or barriers to entry and exit (such as sunk costs). This study presents the first analysis undertaken for a nationally representative group of UK firms on the determinants of exit from exporting, using panel data covering all market-based sectors of the UK during 1997–2003. Our findings suggest that the probability of a firm ceasing to export is directly influenced by its productivity and other attributes associated with firm-level productivity differences (such as size and foreign ownership). Micro-finance factors, such as profitability and the ability to finance through long-term debt, play an additional role. Lastly, sectoral differences (e.g. industrial concentration) also help explain the firm’s exit decision, whilst trade costs lead to a higher probability of exiting from selling internationally.     

R&D Productivity and the Spillover Effects of High‐tech Industry on the Traditional Manufacturing Sector: The Case of Taiwan

This study sets out to estimate the impact of R&D on productivity within the private sector, with further analysis of the different impacts of R&D within high‐tech and traditional manufacturing firms. We also attempt to examine the spillover effects from R&D investment in the high‐tech sector on productivity growth within the traditional industries. Using a sample of 136 large manufacturing firms during the period 1994–2000, we develop an extended version of the Cobb‐Douglas production function model, and our findings suggest that Taiwan's R&D investment had a significant impact on firm productivity growth, with output elasticity standing at around 0.18. When the sample is divided into high‐tech and traditional firms, the R&D output elasticity in high‐tech firms is significantly greater than that found in traditional firms. In addition, the average rate of return in high‐tech firms is much greater than that estimated for other industries. Besides, our empirical results show that, although significant, the impact of R&D investment from the high‐tech sector, on the productivity growth of traditional firms, is rather limited.     

Foreign Direct Investment and Total Factor Productivity Growth: New Macro‐Evidence

Although the role of foreign direct investment (FDI) in facilitating technology transfer is well known in the literature, empirical evidence regarding the effect of FDI on growth is mixed. The contradictory results in the literature may be due to the failure to account for endogeneity and for the abortive capacity of the hosting countries. Using panel data for 49 countries over the period 1974–2008 and the existence of Investment Promotion Agencies in the receiving countries as an instrument, our results show that increased FDI stock leads to higher productivity growth. We also find a significant positive effect on the interaction between FDI stock and distance to the technological frontier, suggesting that the ability of technologically backward countries in absorbing technologies developed at the frontiers increases as more FDI stock is accumulated.     

Exporting and productivity in business services: Evidence from the United States

Does exporting make firms more productive, or do more productive firms choose to become exporters? This paper considers the link between exporting and productivity for a sample of firms in US business services. We find that larger, more productive firms are more likely to become exporters, but that these factors do not necessarily influence the extent of exporting. This conforms with previous literature that there is a self-selection effect into exporting. We then test for the effect of exporting on productivity levels after allowing for this selection effect. We model both the relationship between exporting and productivity, and a simultaneous relationship between export intensity and productivity after allowing for selection bias. In both cases we find an association, indicating that productivity is positively linked both to exporting and to increased exposure to international markets.     

Service Offshoring and Productivity: Evidence from the US

The practice of sourcing service inputs from overseas suppliers has been growing in response to new technologies that have made it possible to trade in some business and computing services that were previously considered non‐tradable. This paper estimates the effects of offshoring on productivity in US manufacturing industries between 1992 and 2000. It finds that service offshoring has a significant positive effect on productivity in the United States, accounting for around 10 per cent of labour productivity growth during this period. Offshoring material inputs also have a positive effect on productivity, but the magnitude is smaller accounting for approximately 5 per cent of productivity growth.     

Outward FDI and Productivity: Micro‐evidence from Slovenia

This paper uses a rich data set of Slovenian manufacturing firms active in the period 1994–2002 that contains information on outward FDI and exports to different markets in order to test three empirical hypotheses that relate the decision for outward FDI to total factor productivity. First, the evidence supports the hypothesis proposed by Helpman, Melitz and Yeaple (2004) that more productive firms are more likely to invest in a foreign affiliate. Second, the hypothesis proposed by Head and Ries (2003 ) that less productive firms may be encouraged to invest in low‐income countries is rejected by the data. However, the main contribution of the paper is to confirm the third hypothesis that required firm's productivity increases with the number of markets that the firm serves, i.e. there is a positive relationship between the number of a firm's foreign affiliates and its total factor productivity.     

International Trade and Economic Growth Nexus in Australia: A Robust Evidence from Time‐Series Estimators

This study examines the effects of international trade on output and tests the null of Granger non‐causality between trade and economic growth in Australia. The single‐equation IV‐GMM, DOLS, FMOLS and NLLS and the system‐based ML estimates consistently support the positive and significant long‐run effects of exports and investment on output. The effects of imports are consistently negative across all the estimates. The OLSEG, RLS and ARDL‐ECM estimates provide a mixed and weak and that overparameterised level‐VAR estimates no support for the effects of trade on output. The estimates of the model with structural breaks provide a dominant support for the cointegrating relationship among variables. In conclusion, the evidence supporting the positive and significant long‐run effects overwhelms the evidence providing a mixed, weak or no support for the effects of trade on output. The results of the study can be inductively generalised to mimic the findings of the literature at large and to suggest that a part of the inconclusiveness over the gains of trade could analogously be ascribed to the use of different methodologies and test statistics across studies. The results support the acceleration of exports and investment to foster the higher levels of output and economic growth.
