Fixed export cost heterogeneity, trade and welfare

Recent literature on the workhorse model of intra-industry trade has explored heterogeneous cost structures at the firm level. These approaches have proven to add realism and predictive power. This paper presents a new and simple heterogeneous-firms specification. We develop a symmetric two-country intra-industry trade model where firms are of two different marginal cost types and where fixed export costs are heterogeneous across firms. This model traces many of the stylized facts of international trade. However, we find that with heterogeneous fixed export costs there exists a positive bilateral tariff that maximizes national and world welfare.     

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.     

Effects of Islamic religiosity on bilateral trust in trade: The case of Turkish exports

Using a rich firm level data set for Turkish manufacturing, we test whether sharing similar religious beliefs with potential contracting parties drives a firm’s first time entry into export markets. We exploit variation in the practice of Islam across Turkish NUTS3 regions and we find that firms located in regions characterised by stronger religiousness are more likely to enter export destinations with a higher share of Muslims among their population. This result is robust to the control for past trade, common language, cultural and migration ties as well as for selective trade policy in favour of politically connected religious business groups. In particular, religious proximity eases export entry for producers of “trust intensive” goods, it favours subsequent foreign market entries and reduces the export exit probability. All in all, our evidence supports an export enhancing effect of religious proximity working through export sunk costs reduction rather than through similarity in preferences.     

eBay’s anatomy

We use a new US-firm-level dataset covering all domestic and international sales made through eBay, an online marketplace, to provide insights about firm heterogeneity in online international trade. One is that the share of firms that export is surprisingly high, at 85%.     

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.     

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.     

Second thoughts on the exporter productivity premium

Abstract Contrary to the prevailing interpretation, this paper shows that the central models of trade with heterogeneous firms ( Melitz 2003 ; Bernard et al. 2003 ) exhibit ambiguous predictions for the exporter productivity premium. This prospect arises because of differences between theoretical and empirical representations of firm productivity. Instead of marginal productivity, we examine in both models the theoretical equivalent of empirically observable productivity (value‐added per employee). Given the presence of fixed export costs or heterogeneous mark‐ups and trade costs, the observable productivity of exporters in proximity to the export‐indifferent firm turns out to be lower than that of non‐exporters; that is, the productivity distributions overlap. The paper reviews empirical literature that reports non‐positive exporter productivity premia in firm‐level data and discusses implications for empirical research on exporter performance, including learning and the role of non‐parametric regressions (stochastic dominance, quantile regressions), fixed costs, and productivity distributions.     

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.     

Deconstructing gravity: trade costs and extensive and intensive margins

Abstract This paper uses data on US exports to decompose exports into the number of exporting firms (the extensive margin) and average export sales (the intensive margin). We show how a range of proxies for trade costs has different impacts on the two margins. Distance has a negative effect on both margins, but the magnitude is considerably larger for the extensive margin. Most of the variables capturing language, internal geography, infrastructure and import cost barriers work through the extensive margin. We show that these results are consistent with a Melitz‐style model of trade with heterogeneous firm productivity and fixed costs.     

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.     

Globalization and firm‐level cost structure

In this study, we draw on economic theories of cost structure and the effects of international trade on firms' productivity to assess firm‐level cost behavior in the context of globalization. We investigate why and how trade openness affects firms' cost structure by examining the changes of fixed inputs along with those in capacity levels. Using a sample consisting of 25 countries from 2000 to 2014, we find that trade openness does significantly affect firms fixed and variable cost inputs, which indicate that production uncertainty along with international trade is essential to the cost structure decision in terms of cost rigidity. Furthermore, larger firms are more likely to adopt a rigid cost structure with higher fixed costs and lower variable costs because they are more involved in the international economy and more exposed to associated uncertainties.     

Trade Policy in the Presence of Technology Licensing*

We consider strategic trade policy when a high‐cost and a low‐cost firm belonging to two different countries compete in quantities in a third country, and technology is transferable via licensing. We characterize the effects of subsidies on (i) licensing payments—a new source of rents, (ii) the decision to license, and (iii) the subsidy bill difference (compared to when licensing is infeasible). We find that, in the presence of licensing, optimal strategic trade policy has several interesting features. For example, even under Cournot competition, optimal policy can be an export tax instead of an export subsidy. Also, unlike results in strategic trade policy with asymmetric costs, we find that optimal export subsidies are not necessarily positively related to the cost‐competitiveness of firms. In other words, governments need not necessarily favor “winners” when licensing is possible. Furthermore, there exist parameterizations such that a government, if it can, might ban licensing.     

Big is Beautiful when Exporting

This paper starts out from the observation that the export ratios of firms (export to sales ratios) vary greatly among firms and that they are systematically higher for larger exporters. We relate the difference in export ratios to firm‐level differences in transport costs. In accordance with the data, we assume that freight rates are a function of firm‐level export volumes. We test our model using Japanese manufacturing firm‐level data. We first estimate the elasticity of the freight rate with respect to firm‐level export volumes at the sector level. When feeding these estimates back into the model, it can explain more than 50% of the variation in firm‐level export ratios.     

Asymmetric Demand Information and Foreign Direct Investment*

We examine the FDI versus exports decision of firms competing in an oligopolistic (quantity‐setting) market under demand uncertainty and asymmetric information. Compared to a firm that chooses to export, a firm that chooses to set up a plant in the host market has superior information about local market demand. In addition to the well‐known tension between the fixed set‐up costs of investment, the additional variable costs of exports and oligopoly sizes, the incentive to invest abroad is explained by the strategic learning effect. FDI may be observed even if trade costs are zero. The analysis is robust to price competition and to the possibility that a foreign firm can engage in both FDI and exports.     

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.     

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.

     

Regional variations in exporters’ productivity premium: Theory and evidence

The international trade literature confirms that the average productivity of exporters is higher than that of nonexporters, while economic geography studies establish that urban firms tend to be more productive than rural ones. By introducing region‐specific transportation costs in a Melitz‐type heterogeneous‐firm trade model, the theory predicts that the minimum threshold productivity level for export is higher but that for survival by serving the local market is lower in the periphery region than in the core. Using Japanese plant‐level panel data, we find evidence supporting the theoretical prediction that exporters in the peripheral regions, especially those distant from the core, have large productivity premiums.     

Financial factors and the margins of trade: Evidence from cross-country firm-level data

Using a large cross-country, firm-level database containing 5000 firms in 9 developing and emerging economies, we study how financial factors affect both firms' export decisions and the amount exported by firms. First, our results highlight the importance of the impact of firms' access to finance on their entry decision into the export market. However, better financial health neither increases the probability of remaining an exporter once the firm has entered, nor the size of exports. Second, we find that financial constraints create a disconnection between firms' productivity and their export status: productivity is only a significant determinant of the export decision if the firm has a sufficient access to external finance. Finally, an increase in a country's financial development dampens this disconnection, thus acting both on the number of exporters and on the exporters' selection process. These results contribute to the literature documenting the role of fixed costs and of the extensive margin of trade in total trade adjustment, and provide micro-level evidence of the positive impact of financial development on trade found by previous literature.     

Risk sharing and export performance with firm heterogeneity

We investigate how market uncertainty affects the export performance of a firm through financial frictions. We first extend Melitz's (2003) heterogeneous firm trade model by incorporating demand shocks, linking the demand uncertainties to the financing costs of firms. In this extension, the default probability is endogenously determined by a firm's productivity and demand uncertainty. Hence, firms with higher productivity or lower market uncertainty are offered lower interest rates and thus show better export performance. As an application, we also show that a risk-sharing mechanism, that pools default risk for a certain group of firms, lowers the default risk. This mechanism allows banks to charge lower interest rates to the member firms and therefore ultimately improves their export performance in both extensive and intensive margins. We find a real-world example of such a mechanism from business groups in Korea. Using Korean firm-level data, we show that the more diversified the business group, the greater the likelihood that its member firms export and the bigger their export revenues. We also show that our results are robust to alternative explanations for Korean business groups’ export competitiveness.     

Trade Liberalization and Heterogeneous Technology Investments

We propose a trade model where heterogeneous firms decide on a productivity‐enhancing technology investment. The model analyzes the impact of multilateral trade liberalization on firm‐ and industry‐level productivity. Freer trade increases the incentives to invest in technology by raising export profits. It also dampens these incentives, however, as profits stemming from domestic sales are reduced. Only exporters benefit from the former positive effect. The shape of the distribution of efficiency draws, the level of trade costs and the technology intensity of the industry are key elements removing the ambiguities regarding the net impact of trade liberalization.
