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.     

Inequality and Saving: Further Evidence from Integrated Economies

Renewed attention to inequality and saving has arisen owing to their pronounced implications for global imbalances and financial crises. We show that the relationship between saving and inequality is negative if savers' funds are borrowed by spending households for consumption as in the USA, but positive if saving is allocated through financial systems to investing firms for production as in China. This theoretical result is largely consistent with empirical evidence found from these two increasingly integrated economies and other related countries by estimating panel‐data models. The policy implication is that inequality must be reduced in order to increase saving in the USA and other Organisation for Economic Co‐operation and Development (OECD) countries and to boost consumption in China and other parts of emerging Asia.     

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.     

Managerial capital,occupational choice and inequality in a global economy

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice and income inequality. Individuals with different managerial talent choose to become entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial capital. The model generates three income classes: low‐income workers facing the prospect of unemployment, middle‐income entrepreneurs managing domestic firms and high‐income entrepreneurs managing global firms. Trade liberalization policies raise unemployment and improve welfare. A reduction in per‐unit trade costs raises top incomes and generates labour‐market polarization. A reduction in fixed exporting costs has an ambiguous effect on top incomes and personal income distribution. Policies reducing labour‐market frictions or the costs of managerial‐capital acquisition create more jobs and improve welfare. The income distributional effects of labour‐market policies depend on which policy is implemented.     

Finance and inequality: Channels and evidence

We provide a framework to interpret the recent literature on financial development and inequality. In many developing countries, access to funding and financial services by firms and households is still very skewed. Recent evidence suggests that poor access does not only reflect economic constraints but also barriers erected by insiders. Inequality affects the distribution of political influence, so financial regulation often is easily captured by established interests in unequal countries. Captured reforms deepen rather than broaden access, as small elites obtain most of the benefits while risks are socialized. Financial liberalization motivated to increase access may in practice increase fragility and inequality, and lead to political backlash against reforms. Thus financial reforms may succeed only if matched by a buildup in oversight institutions. Journal of Comparative Economics 35 (4) (2007) 748–773.     

A Note on Strategic Trade Policy and Endogenous Quality Choice*

This paper shows that some of the main policy implications in Park (2001 ) and Zhou, Spencer, and Vertinsky (2002 ) are sensitive to their assumptions on marginal production costs. The unilaterally optimal policy for investment towards quality improvement is analyzed, assuming constant and non‐negative marginal production costs under vertically differentiated international duopoly. If marginal production costs are different across firms, the optimal policy for each exporting country may be opposite in its sign from that shown by the existing papers under Bertrand competition. The policy reversal may also occur for the low‐quality exporting country under Cournot competition.     

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.     

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.     

Export market participation with sunk costs and firm heterogeneity

In this article we investigate the importance of sunk costs, firm characteristics and spillovers from nearby exporters on a firm's decision to participate in exporting. The empirical analysis involves the estimation of a nonstructural, discrete choice, dynamic model with firm heterogeneity. By using panel data for Estonian companies from 1994 to 1999 we find that: (i) both sunk costs and observable firm characteristics are important determinants of export market participation; (ii) previous history matters, in that, if a firm has been exporting the previous period or the period before, it significantly increases the likelihood of the firm exporting in the current period; (iii) larger firms with high capital intensity and foreign ownership are more likely to be exporters; (iv) operating in an export-oriented industry increases a firm's likelihood of exporting.     

Does Exporting Increase Productivity? A Microeconometric Analysis of Matched Firms

Exporting involves sunk costs, so some firms export whilst others do not. This proposition derives from a number of models of firm behavior and has been exposed to microeconometric analysis. Evidence from the latter suggests that exporting firms are generally more productive than nonexporters. They self‐select, in that they are more productive before they enter export markets, but the evidence suggests that entry does not make them any more productive. This paper investigates exporting and firm performance for a large panel of UK manufacturing firms, applying matching techniques. The authors find that exporters are more productive and they do self‐select. In contrast to other evidence, however, exporting further increases firm productivity.     

Within‐firm wage inequality and firm‐level exports

This paper analyzes changes in within‐firm inequality of hourly wages arising from export shocks to exporting firms in Denmark. We provide causal evidence that export demand shocks increase within‐firm inequality. Decomposing overall inequality into within and between components for occupational and educational groups, the results show that exports lead to a significant increase in within‐group wage inequality but do not affect the between‐group component. We develop a partial equilibrium model, featuring heterogeneous workers, which rationalizes these observations and shows how export demand shocks induce a complementarity effect, leading to increases in wage inequality within firms.     

Skill‐biased heterogeneous firms,trade liberalization and the skill premium

We propose a theory that rising globalization and rising wage inequality are related because trade liberalization raises the demand facing highly competitive skill‐intensive firms. In our model, only the lowest‐cost firms participate in the global economy exactly along the lines of Melitz ( 2003 ). In addition to differing in their productivity, firms differ in their skill intensity. We model skill‐biased technology as a correlation between skill intensity and technological acumen, and we estimate this correlation to be large using firm‐level data from Chile in 1995. A fall in trade costs leads to both greater trade volumes and an increase in the relative demand for skill, as the lowest‐cost/most‐skilled firms expand to serve the export market while less skill‐intensive non‐exporters retrench in the face of increased import competition. This mechanism works regardless of factor endowment differences, so we provide an explanation for why globalization and wage inequality move together in both skill‐abundant and skill‐scarce countries. In our model countries are net exporters of the services of their abundant factor, but there are no Stolper‐Samuelson effects because import competition affects all domestic firms equally.     

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.     

Importing exporters and exporting importers: A study of the decision of Chinese firms to engage in international trade

This paper examines the complex and interdependent relationship between importing and exporting for a panel of Chinese manufacturing firms. We estimate the decision to import and export simultaneously within a dynamic random‐effects bivariate probit framework addressing the endogenous initial conditions problem. Results show that decisions to export and import are simultaneously determined and that sunk‐entry costs play a significant role in a firm's decision to enter international markets. Costs are larger for exporting. We also find a substitution effect between the two decisions. The substitutability between exporting and importing is greater for financially constrained private firms.     

Trade and inequality in a directed search model with firm and worker heterogeneity

This paper integrates the insight that exporting firms are typically more productive and employ higher‐skilled workers into a directed search model of the labour market. The model generates a skill premium as well as residual wage inequality among identical workers. A trade liberalization increases the skill premium and likely increases residual inequality among high‐skilled workers. The calibrated model generates results consistent with the prior literature examining the effect of the Canada‐US Free Trade Agreement on the Canadian labour market: a significant decrease in employment in manufacturing, but only a small change in unemployment and wages.     

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.     

Corruption,product complexity and African exporters

Several studies have shown that African manufacturers perform poorly, especially in comparison to their counterparts from other developing countries. We build on these studies by (a) examining the decision to stop exporting among African manufacturers and (b) investigating whether these decisions can be linked to institutional dimensions (such as corruption). Consistent with previous studies, we observe that a significant fraction of African firms stop exporting every year. Using product complexity as a measure of an industry’s ‘sensitivity’ to corruption, we find that firms in more ‘corruption-sensitive’ industries are more likely to stop exporting if there is an increase in overall corruption in the exporting country. Firm characteristics (such as size and productivity) also seem to influence the decision to stop exporting. Our finding about the relationship between corruption and the decision to stop exporting supports the conventional wisdom that corruption is detrimental to economic performance.     

Limits of the New Institutional Economics Approach to African Development

In the last two decades, there has been a marked shift in the research on Sub-Saharan Africa from standard neoclassical analysis to new institutional economics (NIE). The increasing emphasis on NIE is reflected in a wide range of works by international financial institutions and scholars. However, the NIE approach retains fundamental limitations due to its narrow interpretation of institutions, its over-reliance on analysis of transactions costs and property rights, and its ahistorical attachment to markets and private sector firms as major engines of development. Furthermore, NIE typically fails to look “inside institutions” to identify the complex cultural factors that shape the interests and behaviors of the members of institutions. This paper engages in a critique of NIE analysis of Sub-Saharan Africa’s economic development, and suggests the need for a nuanced analysis of property rights and culture, along with development programs to address inequality and poverty and to foster state-led development.     

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.     

TARIFF POLICY AND WELFARE IN AN INTERNATIONAL DUOPOLY WITH CONSUMER‐FRIENDLY INITIATIVE

The purpose of this paper is to explore how strategic tariff policy and welfare are affected by the consumer‐friendly initiative of foreign exporting firms. We define a firm that is consumer‐friendly or non‐profit‐based if it considers both its own profit and consumer surplus. This paper extends Brander and Spencer by taking the consideration of consumer‐friendly firms into an international duopoly, and within such context examining the tariff policy and welfare. The consumer‐friendly initiative that leads to trade liberalization is a ‘Win‐Win‐Win’ solution in the sense that it is not only beneficial for foreign exporting firms, but also for the government and consumers of the importing country.
