Importing,Exporting, and Innovation in Developing Countries

This study shows the persistent differences in evolution of firms when they are grouped according to their trade orientation as: two‐way traders (both importing and exporting), “exporters‐only”, “importers‐only”, and nontraders. Extending the existing models of firm evolution into an open economy setup by incorporating the importing decision, a simple model is presented and it is empirically shown that: (i) globally engaged firms are larger, more productive, and grow faster than nontraders; (ii) two‐way traders are the fastest growing and most innovative group who are followed by exporter‐only firms; and (iii) estimating the export premium without controlling for import status is likely to overestimate the actual value by capturing the import premium. Robustness of the results is shown by providing evidence from the panel data constructed from the original dataset and controlling for variables that are likely to affect firm evolution.     

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.     

Endogenous Timing in a Strategic Trade Policy Game: A Two-Country Oligopoly Model with Multiple Firms

This paper examines strategic trade policy games where the number of firms in the importing and exporting countries differs and all firms play as Cournot oligopolies. Under the assumption of linear demand and constant marginal cost, we show that, if the number of firms in the exporting country exceeds that in the importing country by more than three, the government of the exporting country chooses to move as a leader, imposing an export tax on firms. The government of the importing country then becomes a follower and imposes an import tariff. This lies contrary to the previous study, which assumed that there is only one firm in each country.     

Export cartel and consumer welfare

The purpose of this paper is to show that export cartels are not necessarily harmful for consumers in the importing countries. Using a strategic trade policy model, we show that, contrary to the harmful effect, product‐market cooperation benefits consumers by affecting the trade policies. We further show that consumers in the importing countries are affected adversely if cooperation is among the governments of the exporting countries, instead of the exporting firms.     

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.     

Political Influence of Firms in the Tradables and Non‐Tradables Sectors: A Cross‐Country Analysis

Recent theoretical studies have shown that firms lobby government agencies to influence the structure of trade policies. This article empirically examines whether firms classified as either exporting or import‐competing (i.e. firms in the tradables sector) have differential levels of political influence relative to domestic firms that only produce non‐traded goods (i.e. firms in the non‐tradables sector). We use a rich firm‐level, cross‐sectional dataset from the World Business Environment Survey to achieve this objective. Results from the analysis reveal that exporting or import‐competing firms do have more political influence relative to domestic firms that neither export nor produce import‐competing goods. Market structure, firm age, firm size, government ownership, and dependence on public infrastructure also affect the extent of political influence that firms have.     

Local export spillovers in France

This paper investigates the presence of local export spillovers on both the extensive (the decision to start exporting) and the intensive (the export volume) margins of trade, using data on French individual export flows, at the product-level and by destination country, between 1998 and 2003. We investigate whether the individual decision to start exporting and exported volume are influenced by the presence of nearby product and/or destination specific exporters, using a gravity-type equation estimated at the firm-level. Spillovers are considered at a fine geographical level corresponding to employment areas (348 in France). We control for the new economic geography-type selection of firms into agglomerated areas, and for the local price effects of firms agglomeration. Results show evidence of the presence of export spillovers on the export decision but not on the exported volume. We interpret this as a first evidence of export spillovers acting through the fixed rather than the variable cost. Spillovers on the decision to start exporting are stronger when specific, by product and destination, and are not significant when considered on all products-all destinations. Moreover, export spillovers exhibit a spatial decay within France: the effect of other exporting firms on the export decision is stronger within employment areas and declines with distance.     

Two Tales on the Returns to Education: The Impact of Trade on Wages

This paper uses micro data from the Current Population Survey combined with data from the US International Trade Commission and Bureau of Economic Analysis to evaluate the impacts of international trade (import penetration and export intensiveness) on wages with a special focus on the returns to education. Consistent with the literature, our empirical analysis provides evidence that the wage rates of similarly skilled workers differ across net‐exporting, net‐importing, and nontradable industries. Our results add to the literature by showing that the wage gap usually found across importing and exporting industries vanishes for highly skilled workers (workers with college degree and beyond) when we control for the cross‐effect between international trade and education, but the wage gap due to international trade still persists for low‐skilled workers. This finding supports the view that education serves as an equalizer and counterbalances the adverse impact from import penetration on wages of highly skilled workers.     

Trade liberalization,forward‐looking firms,and welfare

We set up an oligopolistic model with two exporting firms selling to a third market to investigate the welfare implications of trade liberalization when the exporting firms are forward‐looking. The results show that with cost asymmetry trade liberalization encourages the exporting firms to engage in tacit collusion, which may not only be detrimental to the domestic welfare, but also to the consumer surplus of the importing country. Moreover, we find that tacit collusion is less sustainable if the government of the importing country imposes a lower (higher) tariff on the more (less) efficient exporting firm. If a nonforward‐looking or a forward‐looking cost‐efficient domestic firm exists in the importing country, then trade liberalization also encourages tacit collusion.     

Does export and productivity growth linkage exist? Evidence from the Indian manufacturing industry

This paper examines the interrelation between exporting and productivity performance by using a representative sample of Indian manufacturing firms over the period 1994–2006. Specifically, we attempt to test the empirical validity of the learning‐by‐exporting and the self‐selection hypotheses for our sample firms. In order to investigate the linkage, in the first step, we test for causality between TFP and export intensity of firms. Although overall results are rather mixed and provide some support for both hypotheses, still the empirical results are more favorable for the self‐selection behavior of firms. In the next stage, we attempt to provide evidence on export and productivity linkage that occurs during various phases of transition in the export market. Our results suggest that entering in the export market does not improve productivity performance. However, the decision to exit from the export market does have an adverse effect on the productivity. In addition, our results indicate the presence of a high sunk cost of exporting coupled with perhaps lesser information about foreign markets. Finally, our results also lend some support to the significant role of in‐house research activities and economies of scale in firms' productivity performance.     

考虑港口收费管制的进出口贸易竞争研究

考虑港口的收费管制因素,建立了进出口贸易竞争模型。该模型由一个出口国和两个进口国组成,且各国都拥有一个港口,位于出口国的两家公司均向两个进口国销售商品,并在各个进口国展开市场竞争（古诺竞争或伯川德竞争）,各贸易国的港口根据其是否存在价格管制确定港口收费。针对进出口公司的每种竞争模式,得到了不同的港口收费管制组合下各贸易国的港口收费、港口利润和社会福利,并将竞争均衡结果进行了比较。研究发现： （1）在进出口公司古诺竞争模式下,若三个贸易国的港口都无收费管制（有收费管制）且进出口产品的差异较大 （小）时,各贸易国的社会福利和港口利润均更高; （2）在进出口公司伯川德竞争模式下,若进出口产品的差异较大 （小）,则出口国的港口利润主要取决于港口收费 （贸易量）,而进口国恰好相反; （3）当进出口产品的差异较大 （小）时,进出口公司在古诺 （伯川德）竞争模式下各贸易国的社会福利、港口利润以及港口使用费都更高。     

On the International Linkages between Trade and Merger Policies*

In a three‐country model, this paper investigates linkages between merger incentives of exporting firms and the trade policy of an importing country. When exporting firms come from only one country, the tariff response of the importing country reverses the welfare effects of a merger in the exporting country. If there exist two exporting countries, a merger creates two types of conflicting international externalities. First, a merger in one exporting country increases profits of all firms. Secondly, non‐merged firms lose if the importing country is free to raise its tariff in response to a merger of foreign exporters.     

Impact of nontariff measures on firms in Tunisia

This paper analyzes the effect of nontariff measures (NTMs) on firms in Tunisia. It draws a precise picture of NTMs’ effects on firms’ imports. We use firm‐level data to take into account firm heterogeneity. We explore the impact of NTMs on small vs. medium and large firms. We also consider the differentiated impact of NTMs. Some measures have informational content and help reduce information asymmetries. When the endogeneity issue of NTMs is controlled for, results show an overall positive impact of NTMs on imports. They provide evidence that NTMs are more beneficial to the imports of medium and large firms. Moreover, NTMs with informational content have an import enhancing effect. An extended analysis separating importing and exporting firms from those solely importing suggests that both types of firms benefit from the positive effects of NTMs. This result highlights the need to assist small firms facing NTMs. Furthermore, some NTMs with informational content should be addressed carefully and not considered only as barriers to trade to be eliminated. Instead, harmonization efforts between countries can be a better policy.     

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.     

The Impact of Exporting and Export Destination on Manufacturing Wages: Evidence for Sub-Saharan Africa

This paper investigates wage effects of trade status of African firms. Using data for manufacturing firms, we find a positive overall association between individual earnings and export status. Moreover, the skill wage premium in exporting firms is significantly higher. These results are consistent with either trade inducing higher wages in the exporting country, or with more productive (higher wage) firms self‐selecting into exporting. The results are not robust, however, to disaggregation by export destination. Exporting to outside Africa generates a negative wage premium whereas exporting to African markets yields a positive premium in export firms of the exporting country. This suggests that there is a disciplining effect on the wages of exporting firms only when exporting is to more competitive markets.     

Heterogeneous Firms in Importing: Theory and Evidence from China

In this study, I explore the effects of the financial status of firms on its decisions to import. The import decision is reflected in various aspects, such as whether to import or buy from home market; what types of goods to import, etc. A novelty of this analysis is that I distinguish between ordinary trade and processing trade, which involves importing inputs to be assembled and re-exported. Several novel patterns emerge. Firstly, a firm’s financial status, especially its liquidity, significantly influences its decisions to import. Secondly, regional financial development also has a significantly affect importing decisions. However, a firm’s creditworthiness and regional factors work independently (i.e., regional financial development does not alleviate a firm’s credit constraints). The findings yield implications for developing economies which demand technological spillovers from advanced markets and those which maintain large trade surpluses with the developed economies.     

Foreign Acquisitions in China and Multinationals’ Global Market Strategy

Using firm‐level data from 2000 to 2006, we find that foreign acquisitions in China change the target firms’ export extensive margins. We develop a three‐country model with cross‐border acquisitions to show that the acquirers can alter the targets’ export decision through three possible channels: fixed‐cost jumping, technology transfer and global market reorganization. We find evidence that foreign acquisitions change the Chinese target firms’ probability of exporting to a third market. Technology transfer is not observed. Evidence implies that fixed‐cost jumping is used to enable the targets to export, while global market reorganization is a key motive for the acquirers to withdraw the targets from the export market.     

The returns to exporting: evidence from UK firms

Abstract The question of learning versus self‐selection has dominated the micro‐econometric literature on firm export decisions without leading to any firm conclusions. In part this reflects the limited information content of the data typically used. In this paper we use survey data on UK firms to offer some new insights into this debate. We find that the majority of firms report benefits to exporting across a wide range of performance measures, including size, profitability, and the introduction of new products. These effects do not decline as the number of years of exporting rises if the export intensity of the firm rises.     

Sunk costs of exporting and the role of experience in international trade

This paper estimates the importance of destination‐specific sunk costs of exporting and investigates the role of firms' previous experience in international trade for the decision to export to a market. While destination‐specific sunk costs are important, firms' experience in international trade can help to overcome these costs more easily. In particular, import experience from a market is found to facilitate exporting to this country and export experience from other markets can increase the probability of exporting to a country. This latter effect turns out to be conditional on the characteristics and number of markets served by a firm.     

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.
