Export Destination,Product Quality and Wages in a Middle‐Income Country. The Case of South Africa

A robust finding in the firm‐level literature is that exporting firms pay higher wages. Using South African data this paper investigates the relationship between export destination and wages at a worker level. South Africa, a middle‐income country, has two distinct main export markets—a regional market where per capita incomes are lower than at home, and an international market with higher per capita incomes. Our estimates show that workers in firms that export to the region earn less than those that produce for the domestic market. Those in firms that export outside the region earn more than either domestic producers or region‐only exporters. Much of this difference in wages can be explained by the premium the different types of exporters pay for skills. These results support previous studies which suggest that export destination is related to product quality which in turn is related to worker quality and therefore wages.     

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.     

WHY FOREIGN OWNERSHIP MAY BE GOOD FOR YOU*

We develop a two‐country model with heterogeneous producers and rent‐sharing at the firm level. We identify two sources of a multinational wage premium: A composition effect because multinational firms are more productive, make higher profits, and pay higher wages, and a firm‐level wage effect, because a firm makes higher global profits and thus pays higher wages in its home market when becoming multinational. With two identical countries, the wage premium is fully explained by firm characteristics. Allowing for technology differences between countries, a residual wage premium exists in the technologically backward country but not in the advanced country.     

International Trade and Collective Bargaining Outcomes: Evidence from German Employer–Employee Data

In theoretical trade models with variable mark‐ups and collective wage bargaining, exposure to international markets might reduce the exporter wage premium. We test this prediction using linked German employer–employee data covering the years 1996–2007. To separate the rent‐sharing mechanism from assortative matching, we exploit individual worker information to construct profitability measures that are free of skill composition. Our results show that rent‐sharing is less pronounced in more export‐intensive firms or in more open industries. The exporter wage premium is highest for low‐productivity firms. In line with theory, these findings are unique to the subsample of plants covered by collective bargaining.     

The Exporter Wage Premium Reconsidered—Destinations,Distances and Linked Employer–Employee Data

This study uses detailed, reliable and up‐to‐date linked employer–employee data that take account of both the demand and the supply side of the labor market to challenge the conventional wisdom of a universal exporter wage premium. It investigates whether for German establishments an exporter wage premium can be found irrespective of export destination and the distance between export origin and destination. As expected, it finds that exporters generally pay higher wages than non‐exporters, but it also shows that only exporting to certain countries is associated with a wage premium. Moreover, such a premium exists only for establishments that ship goods over a relatively long distance.     

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 Location of Firms in Unionized Countries*

This paper develops a two‐country economic geography model with Cournot competition, where the labor markets are unionized so that trade unions bargain efficiently with each firm over wages and employment. Agglomeration forces are present due to wage premia obtained by the trade unions. It is shown that if the bargaining power of unions differs across countries then, as trade costs are reduced, the country with relatively weak unions gradually acquires all firms. However, for a range of trade costs, it is also a locally stable equilibrium for all firms to locate in the country with strong unions.     

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.     

INTERNATIONAL WELFARE AND EMPLOYMENT LINKAGES ARISING FROM MINIMUM WAGES*

We formulate a two‐country model with monopolistic competition and heterogeneous firms to reconsider labor market linkages in open economies. Labor market imperfections arise by virtue of country‐specific real minimum wages. Abstracting from selection of just the best firms into export status, standard effects on marginal and average firm productivity are reversed in our model, yet there are significant gains from trade arising from employment expansion. In addition, we show that with firm heterogeneity an increase in one country’s minimum wage triggers firm exit in both countries and thus harms workers at home and abroad.     

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.     

The formal sector wage premium and firm size

We show theoretically that when larger firms pay higher wages and are more likely to be caught defaulting on labor taxes, then large-high wage firms will be in the formal and small-low wage firms will be in the informal sector. The formal sector wage premium is thus just a firm size wage differential. Using data from Ecuador we illustrate that firm size is indeed the key variable determining whether a formal sector premium exists.     

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.     

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.

Who Trades with Whom? Exploring the Links between Firms' International Activities,Skills, and Wages

Using firm‐level data on the Italian manufacturing industry, we examine how trade activities are related to workforce composition and wages. We contribute to empirical research on these issues in three ways. First, we provide new evidence that is consistent with multi‐attribute models on firm heterogeneity and trade. We show that even after controlling for various company characteristics, including size and capital intensity, exporters still pay higher wages and employ more skilled workers than nonexporters. Second, we consider engagement in international transactions, either by means of exports, imports, or a combination of the two. We show that failing to control for importing activities may bias upward export premia. Third, we look at how the wage and the employment structures of trading firms change with the country of destination and origin of trade flows. We find that wage and skill premia are influenced by the characteristics of partner countries.     

Directed search with heterogeneous firms: an experimental study

Directed search models labor markets where workers observe wages before deciding where they will apply. This paper tests this model for the case of heterogeneous firms in a laboratory experiment. The theory predicts that more productive firms offer higher wages and workers apply more often to these higher wages. In consequence, more productive firms are more likely to match and the market is more efficient than the prediction of an alternative model where search is random. The main results of the experiment are that average firms offer wages that are close to or a little lower than the theoretical predictions but highly variable and workers apply more often to high offers but not to the extent predicted. The markets are no more efficient than random search predicts, because of the variation in wage offers.     

企业出口与生产率的关系——基于中国工业企业数据的实证研究

采用1998—2007年中国工业企业数据,对出口与生产率的关系进行了再探讨,具体研究了出口企业是否具有更高的生产率、企业在做出口决策的过程中是否存在自我选择机制以及出口行为本身是否能促进企业生产率的增长。研究结果显示:当用TFP衡量生产率时,企业出口决策中存在自我选择机制,因此出口企业的生产率相对较高——这与异质企业贸易模型的预期结果一致;当用劳动生产率(人均附加值)衡量企业生产率时,则"生产率悖论"存在,即出口者的生产率反而较低;当企业刚进入出口市场时,其生产率会经历短期的快速增长,但从长期来看,出口对企业生产率增长的作用在整体上是负向的。     

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.     

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.     

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.
