Internet Technology and the Extensive Margin of Trade: Evidence from eBay in Emerging Economies

Online platforms such as eBay offer technologies that make it easier for firms to export. This paper dissects a new firm‐level dataset that covers sales made through eBay by sellers based in 21 emerging economies to provide a new lens through which to look at the effect of trade costs on the extensive margin of trade. Comparing eBay sellers with “offline” firm‐level data from the World Bank's Exporter Dynamics Database allows us to test whether the observed trade patterns on eBay fit with the trade‐liberalization predictions of heterogeneous‐firm models. We find that eBay firms export to more destinations, suggesting low destination‐specific fixed costs on eBay. We then show that the distribution of export destinations across eBay sellers is well approximated by a balls‐and‐bins model of frictionless trade, suggesting eBay indeed lowers fixed export costs. Finally, we compare the gravity of eBay with that of offline trade and find geographic distance, languages, and trade agreements to matter less for online trade.     

Decomposing service exports adjustments along the intensive and extensive margin at the firm‐level

Using a panel data set of Austrian service exporting firms this paper examines the determinants of service exports at the firm/destination country level. We implement a random effects Heckman sample selection firm‐level gravity model as well as a fixed effects Poisson model. Expected firm‐level service exports are decomposed into the intensive and extensive margins of adjustment as a response to counterfactual changes. We find market demand to be a key determinant. Results also suggest high service export potentials due to regulatory reform in partner countries within the EU. Adjustments at the extensive margin only play a marginal role. Increases in firm size as well as changes in distance related costs are most effective in developing new export relationships in services.     

What makes a successful export? Evidence from firm‐product‐ level data

Abstract We analyse a very rich and unique panel database that provides information on exports at the firm‐product level. Motivated by the recent theory of multi‐product firms, we investigate what determines the survival of products in the export mix to find that, in export dynamics, characteristics of the product as well as that of the firm matter. In particular, firm productivity as well as product scale and tenure are associated with a higher export survival rate. This suggests, in line with theory, that there are firm‐ as well as firm‐product‐specific competencies that are important for shaping firms’ export mix.     

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.     

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.     

Export Spillovers of FDI on China's Domestic Firms

This paper examines the horizontal and vertical export spillovers of foreign direct investment (FDI) on China's manufacturing domestic firms by using firm‐level census data over the period of 2000–03. Based on a Heckman two‐step procedure combining first differencing and instrumental variable regression techniques, it is found that FDI has had a positive impact on the export value of domestic firms mainly through backward technology spillovers and a positive impact on the export‐to‐sales ratio of domestic firms through horizontal export‐related information spillovers. After decomposing FDI by different market orientation and domestic firms by different ownership, the paper finds that the positive impact on domestic firms' export values is mainly from the nonexporting and the exporting foreign‐invested enterprises while the positive impact on domestic firms' export‐to‐sales ratios is mainly from the high‐exporting foreign‐invested enterprises. Both types of export spillovers are mainly diffused to domestic non‐state‐owned enterprises.     

Sunk Costs,Firm Heterogeneity,Export Market Entry and Exit: Evidence from India

This paper analyses the role of sunk costs and firm heterogeneity in firm decision to enter and exit export markets. Employing rich firm-level data on Indian manufacturing firms, the study points out that sunk costs in terms of previous export experience significantly explain entry and exit decisions of firms in the export market. The first set of analysis involves estimation of dynamic discrete choice model using random effects probit correcting for initial conditions problem. We find evidence that previous export experience (sunk costs) matters for export decision. However, importance of sunk costs is found to depreciate rapidly. Further, analysis across sub-sample of firms accounting for firm heterogeneity factors like size and product level information supports the hypothesis of sunk costs. Second set of analysis involving firm survival in export markets using discrete-time hazard models shows evidence of negative duration dependence. We observe that those firms which continue to export for few years are less likely to exit from export markets.

     

Reaching up and reaching out: The impact of competition on firms’ productivity and export decisions

Using firm‐level data from 139 countries, this paper investigates the effect of competition in both the domestic and foreign markets on firm productivity and export decisions. Applying a sample selection endogenous treatment (SSET) Poisson model that tackles both the issue of endogenous sample selection and endogenous treatment at the same time, we document robust evidence that strong competition in the domestic market propels firms to be more productive, and decreasing domestic competition increases firms’ propensity to export. However, firms’ export intensity (i.e. how much they export) is not directly influenced by competition in the domestic market. Moreover, lower competition in the foreign market increases the propensity of domestic firms to export, enlarging the set of exporting firms to include firms with relatively smaller export amounts.     

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.     

Credit Constraints,Technology Choice and Exports: A Firm‐level Study for Latin American Countries

In this paper, constraints on technology choice and credit access are introduced into a firm‐level trade model in a dynamic setting in order to explain factors that limit benefits to a firm from trade liberalization. Theoretical analysis shows that firms face credit constraints depending on their initial productivity and the cost of credit. As a result, credit‐constrained firms may not be able to cross the minimum productivity threshold needed to enter and compete in a foreign market. Empirical analysis using firm‐level panel data for six Latin American countries confirms that financial constraints negatively influence firms' export and investment decisions.     

Exporting and Productivity: The Effects of Multi‐Product and Multi‐Market Export Entry

Empirical studies on the micro‐level effects of exporting on productivity pay usually little attention to the potentially heterogeneous effects of the different modes of export market entry. We show that multi‐product export entry is associated with higher post‐entry productivity compared to other firms. This can imply significant benefits from experimentation with different products. Our analysis is based on detailed export data from full population of firms in Estonia, disaggregated for each firm by export markets and individual products.     

Sizing Up the Impact of Embassies on Exports

The purpose of this study is to test for the effects of trade promotion via the foreign service. The theory of trade with heterogeneous firms predicts that unilateral trade promotion allows medium‐sized firms to export. We investigate the effects of trade promotion using firm‐level data and information on the opening and closing of embassies abroad from the very similar neighboring countries Sweden and Norway. We use a difference‐in‐difference specification where firms from Norway are used as a control group for Swedish firms. Our results show that large firms as well as medium‐sized firms respond to the opening of embassies.     

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.     

A theory on the role of wholesalers in international trade based on economies of scope

This paper offers a theoretical foundation for the existence of wholesalers and other intermediaries in international trade and analyzes their role in an economy with heterogeneous manufacturing firms and fixed costs of exporting. Wholesalers are assumed to possess a technology such that they can buy manufacturing goods domestically and sell in foreign markets and they can, unlike manufacturers, export more than one good. A wholesaler therefore faces an additional fixed cost, which increases in the number of goods it handles. The presence of wholesale firms leads to productivity sorting. The most productive firms export on their own by paying a fixed cost, but a range of firms with intermediate productivity levels export through international wholesalers. A higher fixed cost of exporting to a destination means that wholesalers handle: (i) a higher share of total export volumes to this destination and (ii) a higher share of the exported product scope (i.e., the number of exported products) to this destination. A higher fixed cost of exporting gives wholesalers a larger role, since these can spread the fixed cost across more than one good. The wholesale technology therefore exhibits economies of scope. An empirical analysis using Swedish firm‐level data supports the main assumption and predictions of the model.     

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.     

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.     

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.     

Export promotion and intra‐industry reallocations

Publicly funded/subsidized export promotion agencies reducing informational barriers to export and thus firm‐level fixed/sunk costs of exporting are present in most countries. This paper develops a two‐country one‐sector heterogeneous firms model with origin‐specific publicly funded export promotion agencies and shows how the public good nature of export‐relevant information and the ability to engage in global public affairs may rationalize the existence of such agencies. A novel finding of the model is that gains from export promotion are shared with the trade partner via intra‐industry reallocations.     

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.     

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.
