This article shows how to use the publicy-available firm-level surveys produced by the World Bank Enterprise Surveys (WBES) to reproduce the stylized facts that characterize firm heterogeneity and its relationship with global engagement, as established by Bernard et al. (2007) for manufacturing firms in the U.S. The article describes how to incorporate this exercise in different teaching activities such as small group classes and homework and courseworks assignments. The activities proposed allow students to develop skills handling and analyzing firm-level data and, since WBES surveys are available for more than 150 countries since 2002, they offer an unique opportunity to evaluate the extent to which the stylized facts established from U.S. data are also representative of countries of different size and stage of development. The activities proposed connect the theory of trade with heterogeneous firms to the real-world empirical evidence that motivated the development of these models.

Received wisdom suggests that most exporters sell most of their output domestically. We show, however, that the distribution of export intensity varies substantially across countries and is often bimodal, displaying “twin peaks”—that is, large shares of both low- and high-intensity exporters coexisting alongside each other within a country. We reconcile this new stylized fact with an otherwise standard model of trade in which firms face firm-destination-specific revenue shifters that follow a lognormal distribution with sufficiently high dispersion. We structurally estimate the model and show that differences in countries’ size relative to the rest of the world can account for most of the observed cross-country variation in the distribution of export intensity in our data. While policies that incentivize firms to export a high share of their output account for a substantial share of the variation in the dispersion of firm-destination revenue shifters, they cannot fully account for the widespread prevalence of twin peaks around the world.

Special economic zones (SEZ), one of the most important instruments of industrial policy used in developing countries, often impose export share requirements (ESR). That is, firms located in SEZ are required to export more than a certain share of their output to enjoy a wide array of incentives—a practice prohibited by the World Trade Organization (WTO) Agreement on Subsidies and Countervailing Measures. In this paper we exploit the staggered removal of ESR across products and over time in the SEZ of the Dominican Republic—a reform driven by external commitments to comply with WTO disciplines on subsidies—to evaluate how ESR affect export performance at the product and firm levels. Using customs data on international trade transactions from the period 2006 to 2014, we find that making the Dominican SEZ regime WTO‐compliant made SEZ more attractive locations for exporters to be based in. The reform, however, did not have a significant effect on the country's exports or on the share of export value originating from SEZ.

This paper finds that a greater reliance on foreign market sales increases the volatility of firms’ stock returns, using high‐frequency data for publicly listed Japanese manufacturing firms over the period 2000–10. The two margins of global engagement we consider, namely, exports and sales via foreign affiliates (horizontal foreign direct investment), have both a positive and economically significant effect on firm‐level volatility. We find, however, that increasing the intensity of sales through foreign affiliates has a stronger effect on volatility than a similar change in export intensity. We also uncover evidence consistent with the notion that firms’ need to use external finance to cover the substantial costs involved in reaching foreign consumers can be an important channel through which firms’ participation in international markets increases their exposure to economic uncertainty.

This paper presents a simple model of subsidies with export share requirements (ESR) in a heterogeneous firm environment. A two-country general equilibrium version of the model with a single 100% ESR is calibrated using firm-level data from the 2002 wave of the Business Environment and Enterprise Performance Survey collected by the World Bank for China. The calibrated model is used to gauge the change in subsidies with ESR that is consistent with the fall in the share of ‘pure exporters’, firms exporting all their output, observed in China, from 25.7% in 2002 to 11.1% in 2013. Our results indicate that a 6.9% reduction in the ad-valorem subsidy rate available to firms that export all their output is consistent with the observed fall in their share of exporting firms. Expenditure in subsidies (as a share of value-added) falls by 66% and welfare in China increases by 1.76% while real income in the rest of the world falls by 0.59%.
