Learning‐by‐Exporting Revisited: The Role of Intensity and Persistence*

Two non‐mutually exclusive hypotheses can explain the empirically established export premium: self‐selection of more productive firms into export markets and learning‐by‐exporting. This paper focuses on how the temporal dimension of firms' exporting activities and the intensity of exports influence the scope of learning effects. Using a panel of Swedish firms and dynamic generalized method of moments estimation, we find a learning effect among persistent exporters with high export intensity, but not among temporary exporters or persistent exporters with low export intensity. For small firms, exports boost productivity among persistent exporters with both high and low export intensity, but the effect is stronger for persistent export‐intensive small firms.     

Export Market Dynamics and Plant‐Level Productivity: Impact of Tariff Reductions and Exchange‐Rate Cycles*

In this paper, we examine how changes in tariff rates and industry‐specific real exchange rates affect the entry/exit process to export markets and productivity growth. Using the experience of the Canadian manufacturing sector over three decades, we find that firms in export markets enjoy faster productivity growth than non‐participants. The size of the growth advantage depends on whether real exchange rates are increasing or decreasing. The increase in the value of the Canadian dollar during the post‐2000 period almost completely offset the productivity growth advantages enjoyed by new exporters during this period.     

Productivity Performance of Export Market Entry and Exit: Evidence from Indian Firms

This paper contributes to the literature on exporting and firm productivity, focusing on export entry (efficiency), learning (post‐entry growth) and exit (inefficiency) by Indian firms. Drawing on 7000 firms during 1989–2009, our main objective is to examine the effect of exporting on firm productivity, correcting for selection bias using propensity‐score matching, which allows a “like‐for‐like” comparison between new exporters and nonexporters. Robust to different matching estimators, we find evidence of learning‐by‐exporting that new exporters acquire rapid productivity growth after entry, relative to nonexporters. We also find that (1) exporters are more productive than nonexporters; (2) productive firms tend to self‐select in entering the exporting market, and (3) least productive exporters are found to exit the export market as they experience adverse productivity effect prior to the year of exit. Our robust result on learning‐by‐exporting suggests that entering export market does appear to be a channel explaining the Indian recent growth miracle.     

EXPORT‐MARKET DYNAMICS AND THE PROBABILITY OF FIRM CLOSURE: EVIDENCE FOR THE UNITED KINGDOM

This study presents the first empirical analysis of the determinants of firm closure in the United Kingdom with an emphasis on the role of export‐market dynamics, using panel data for a nationally representative group of firms operating in all‐market‐based sectors during 1997–2003. Our findings show that the probability of closure is (cet. par.) significantly lower for exporters, particularly those experiencing export‐market entry and exit. Having controlled for other attributes associated with productivity (such as size and export status), the following factors are found to increase the firm's survival prospects: higher capital intensity and TFP, foreign ownership, young age, displacement effects (through relatively high rates of entry of firms in each industry), and belonging to certain industries. Interestingly, increased import penetration (a proxy for lower trade costs) leads to a lower hazard rate for exporting entrants and continuous exporters, while inducing a higher hazard rate for domestic producers or those that quit exporting.     

Intra‐firm trade,exporting, importing,and firm performance

Abstract This paper examines firm heterogeneity in terms of size, wages, capital intensity, and productivity between domestic and foreign‐owned firms that engage in intra‐firm trade, firms that export and import, firms that import only, and firms that export only. As previously documented, heterogeneity between different groups of trading firms is substantial. Taking into account intra‐firm trade in addition to exporting and importing yields new insights into the productivity advantage previously established for exporting firms. The results presented here show that this premium accrues only to exporters that also import and to exporters that also engage in intra‐firm trade, but not to firms that export only. Using simultaneous quantile regressions, the paper illustrates that heterogeneity within different groups of trading firm is equally large. Some of this within‐group heterogeneity can be attributed to differences in trading partners.     

The Export Promoting Effect of Emigration: Evidence from Denmark

Ethnic networks exhibit the potential to lower barriers to trade. The paper identifies the export‐promoting effect of emigration on the firm‐level using Danish data for the year 2001. Accounting for taste similarity, self‐selection and unobserved heterogeneity, three main findings are established. First, the elasticity of manufacturing exports to emigration is robust and of similar size as the effect of immigration. Secondly, only immigration encourages market entry but not emigration, suggesting that variable cost reductions and demand for home‐country products are the driving force of emigrant network effects. Thirdly, benefits from emigration accrue exclusively to low‐productivity firms.     

Market size and entry in international trade: Product versus firm fixed costs

This paper develops a theoretical framework to infer the nature of fixed costs from the relationship between entry patterns in international markets and destination market size. If fixed costs are at the firm level, firms take advantage of an intrafirm spillover by expanding firm‐level product range (scope). Few firms enter with many products and dominate international trade. If fixed costs are at the product level, an interfirm spillover reduces the fixed costs to export for all firms producing the product. The resulting entry pattern consists of many firms exporting different varieties of the same product. Using cross‐country data on firm and product entry, I find empirical evidence consistent with product‐level costs. More firms than products enter in larger markets offering their consumers lower prices and a greater variety of goods within the product category.     

企业出口前研发投入、出口及生产率进步-来自中国制造业企业的证据

出口会导致企业生产率提高么?什么因素会影响出口的生产率效应?本文采用2001—2007年中国规模以上制造业企业调查数据估计了出口的即期和长期生产率效应。我们认为企业出口之前的研发投入可以通过增加企业的吸收能力来提高出口的生产率效应。通过采用倾向得分匹配的计量方法,我们发现:(1)平均看来,对于首次出口的企业,其出口当年企业生产率有2%的提升,然而在出口之后的几年中这种提升效应均不显著。(2)对于有出口前研发投入的企业,出口对生产率存在着持续且幅度较大的提升作用;但对于没有出口前研发投入的企业,出口对生产率没有显著的提升效应或提升效应短且较弱。(3)出口对生产率的提升效应随企业从事出口前研发年数的增加而提高。     

Firm productivity and importing: Evidence from Chinese manufacturing firms

This paper investigates various aspects of the relationship between firm productivity and importing for a large sample of Chinese firms between 2002 and 2006 making a distinction between the origin, variety, skill and technology content of imports. Employing a random effects probit model and a propensity score matching with difference‐in‐differences (PSM–DID) approach and treating imports as endogenous in our measure of total factor productivity (TFP) (De Loecker 2007), we test the self‐selection and learning‐by‐doing hypotheses. Our results show evidence of a bi‐directional causal relationship between importing and productivity. Although importing firms tend to be more productive before entering the import market, once they start importing firms experience significant productivity gains for up to two years following entry. We also find evidence of learning effects following the decision to import, which is stronger when import starters source their products from high‐income economies, import a wider variety of products and import products with a higher skill and technology content. A number of robustness checks confirm the learning effects of importing on TFP growth.     

GROWTH,INTER‐INDUSTRY AND INTRA‐INDUSTRY COMPETITION AND WELFARE*

In this paper we introduce strategic interaction between firms in an R&D growth model which captures both the intra‐industry competition between firms operating within an industry and the inter‐industry competition between firms in different industries. We show that the more substitutable the goods produced within each industry (across industries) are, that is, the more intense the intra‐industry (inter‐industry) competition, the higher is the growth rate. In the comparison between social optimum and a decentralized economy, it is shown that the market outcome is characterized by inefficiently high entry of firms within each industry and insufficient productivity growth.     

Exporters in cross‐section: Direct versus intermediated trade

How do producers that export their goods directly differ from those that export through trade intermediaries? We take a standard model of trade with heterogeneous firms and add heterogeneity in quality to the usual heterogeneity in productivity. Modeling trade intermediaries as increasing marginal costs but decreasing fixed costs of exporting, we find that only firms with the highest quality‐adjusted productivity levels choose to export directly. Under certain parameter restrictions, the model shows that direct exporters tend to be larger and charge higher prices for their goods. In contrast to the literature, using Chinese customs data, we confirm that direct exporters do charge higher prices for their goods.     

Export rivalry and exchange rate pass‐through

In this paper, we investigate the influence of market rivalry on firm‐level exchange rate pass‐through. Similar to Bloom et al. Econometrica, 80 , 1347–1393 (2013), we define market rivalry as product market proximity, and expect the cross market spillovers, that is, through leaked information or reputation, to affect firm‐level export price. Using a comprehensive dataset from Chinese exporters for the 2000–2007 period, we find that in response to a higher degree of market rivalry firms are less responsive to exchange fluctuations. This unresponsiveness suggests a higher degree of exchange rate pass‐through. The influence of market rivalry is stronger among firms that export consumption and heterogeneous products, and to developed countries. Our results are robust to different measures of market rivalry and specifications.     

THE RELATIONSHIP BETWEEN EXPORT STATUS AND PRODUCTIVITY IN SERVICES: A FIRM‐LEVEL ANALYSIS FOR SPAIN

This paper analyses the relationship between export status and productivity in a major service exporter, Spain, during 2001–07. I find that exporters in the services sector are 45 percent more productive than non‐exporters. This productivity premium is larger for firms that supply non‐internet‐related services than for firms that supply internet‐related services. The results show that exporters were more productive than non‐exporters before beginning to export, and also that exporting increases productivity growth; however, this positive shock vanishes quickly.     

Who Exports Better Quality Products to Smaller or More Distant Markets?

The role of across‐firm differences in product quality and firms' competitiveness in determining the spatial patterns of within‐product export unit values across destinations is examined in this paper. Using product level export data, it is shown that the average export unit value of a product shipped from the USA or Korea increases with distance and decreases with destination market's size. However, within‐product average unit values for products exported from China and India decrease with distance and increase with market size. To interpret these different spatial patterns of unit values across exporting countries, model of quality heterogeneity is developed in which firms differ in their workers' skill level and higher‐skilled workers show greater productivity in performing tasks that improve product quality. The model predicts that in relatively skill‐abundant countries, exporting firms specialize in high‐quality products using relatively cheap skilled labor, whereas, in relatively skill‐scarce countries, firms that produce lower‐quality products are more competitive.     

Innovation,trade and multi‐product firms

This paper contributes to the literature on the relationship between innovation and exports by developing a model that emphasizes the role of product innovation in explaining heterogeneity in export behaviour both across and within firms. The dynamic model assumes that firms invest to maintain and increase the portfolio of products they sell: innovation is a stochastic process whereby the probability to capture new business opportunities is a function of the number of goods already sold. Crucially, the model assumes two independent mechanisms to drive the extensive and the intensive margins of a firm's export. The resulting lack of (built‐in) correlation between the two margins is well reflected in the data and represents the main contribution of our theoretical framework. The model is consistent with several other empirical regularities that characterize multi‐product firms, such as the heavy tail in the distribution of the number of products exported by each firm, the strict hierarchy in the sales of products across markets, the substantial degree of product churning and the highly skewed distributions of export sales.     

Export revenue and quality: Firm‐level evidence from developing countries

I combine firm‐level export data from eight low‐income and middle‐income countries to test the relation between export price and export revenue. Across‐firm estimations show a strong positive association between export price and export revenue. Within‐firm estimations show that firms generate larger export revenue from their high‐price products. The positive correlation between export price and export revenue is strong for manufactures, weak for primary commodities, and nonexistent for extractables. Results are robust to using an alternative quality measure and controlling for exporters’ market power.     

Exporting, productivity and agglomeration

Economic analysis of adjustment to globalisation has shifted from countries and industries to firms and plants. One particularly fruitful area for research has been aspects of entry to, participation in and exit from export markets. This paper contributes to that literature. Its focus is the exporting behaviour of manufacturing firms in the United Kingdom. To isolate the impact of participation in export markets we use nearest neighbour matching. For 1988-2002, we find evidence that spillovers associated with agglomeration can raise the probability of export market entry and once entry has occurred there may be additional productivity benefits. Survival is driven partly by size and total factor productivity and partly by industry characteristics.     

Vertical Integration,Firms’ Entry,Exit, Strategic Shifts,Age, and The Productivity Growth in Korea's Core Growth‐Leading Industries

This study attempts to measure the impact of firms’ entry, exit, strategic shifts, and age on the productivity growth of Korea's three core growth‐leading industries and their vertical integration with capital share (VI) firms and non‐VI (NVI) firms in view of the 2008 global financial crisis and the institutional push by the Korean Government. A stochastic frontier production model was applied to firm‐level panel data from 2006 to 2011 for Korea's automobile, electronics and general machinery industries. The results show that exogenous shocks to the market triggered large‐scale resource reallocations from firms with declining productivity to firms with less declining or rising productivity, and market share reallocation between VI firms and NVI firms. The Korean Government's institutional push led the productivity growth of NVI firms to reach their highest levels in 2010. In a VI structure, a structure comprising VI firms only, the agency problem dominated the synergies of secure supply chains and saving on transaction costs, while NVI firms endeavoured to raise their productivity to step into a VI structure to secure stable supply chains, only to find their R&D initiatives stagnated once they took on the VI structure. Therefore, efficient resource reallocation is hindered by the agency problem within the bounds of vertically integrated industrial structures.     

Trade and productivity: Self-selection or learning-by-exporting in India

Recent literature tried to explain the Indian growth miracle in different ways, ranging from trade liberalization to industrial reforms. Using data on Indian manufacturing firms, this paper analyzes the relationship between firm's productivity and export market participation during 1991–2004. While it provides evidence of the self-selection hypothesis by showing that more productive firms become exporters, the results do not show that entry into export markets enhances productivity. The paper examines the explanation of self selection hypothesis for total factor productivity differences across 33,510 exporting and non-exporting firms. It uses propensity score matching to test the learning-by-exporting hypothesis. In line with the prediction of recent heterogeneous firm models of international trade, the main finding of the paper is: more productive firms become exporters but it is not the case that learning by exporting is a channel fuelling growth in Indian manufacturing.     

Multi‐product exporters,variable markups and exchange rate fluctuations

In this paper we investigate how firms adjust markups across products in response to fluctuations in the real exchange rate. We estimate markups at the market–product–plant level using detailed panel production and cost data from Mexican manufacturing between 1994 and 2007. Exploiting variation in the real exchange rate in the aftermath of the peso crisis in December 1994, we provide robust empirical evidence that plants increase their markups and producer prices in response to a real depreciation and that this increase is greater for products with higher productivity. Thus, we provide direct evidence for the theoretical mechanism of variable markup response behind incomplete and heterogeneous exchange rate pass‐through on producer prices. Our empirical methodology allows us to decompose the producer price response to exchange rate shocks into a markup and a marginal cost component using our markup estimates. Using these estimates, we establish that marginal cost at the product–plant level increases more in response to real exchange rate depreciation if the plant has higher share of imported inputs.
