July 2019The Margins of Trade
with Jonathan Eaton: w26124
We introduce quality differentiation and an extensive margin of products into a standard quantitative, general equilibrium model of international trade. Both the quality and the quantity of a product play a role in its contribution both to consumption and to production. The framework allows bilateral trade to vary at the extensive and intensive margins and the intensive margin of trade to vary at the quantity and unit-value margins. We estimate the parameters of the model using bilateral data on trade flows and on unit values in trade. The model captures (i) the well-documented increasing relation between unit values and both importer and exporter per capita income and (ii) how the extensive margin rises with importer and exporter size. But, unlike other contributions to the literature co...
April 2018Escaping Import Competition in China
with Ann Harrison: w24527
In a stylized model, firms differentiate their products to escape import com- petition. Facing a nested CES demand, each firm chooses between a nest with competitors and its own nest under higher costs. The profit from differentiation is an inverted U-shaped function of firm productivity. It increases with import competition and is lower than the social benefit. Differentiation increases the gains from trade. In establishment data from China spanning its 2001 WTO accession, tariff cuts are associated with increases in productivity, introduction of new goods, switches to skill-intensive sectors. Markups in the model explain the large increases in revenue productivity among small firms and input suppliers.
March 2014Trade, Skills, and Quality Upgrading: A Theory with Evidence from Colombia
with Marcela Eslava, Daniel Xu: w19992
We develop a model of international trade with heterogeneous firms and endogenous quality choices. Producing higher quality involves returns to scale, it is intensive in skilled labor and high-quality inputs. Firms' quality choices are interrelated because firms sell their goods to consumers and to other firms. We estimate the model using data on manufacturing plants in Colombia before the trade liberalization, simulate a counterfactual liberalization and compare the results to post-liberalization data. Like other unilateral trade liberalizations in developing countries, the skill premium and skill intensity in manufacturing increased, and the size of firms decreased in Colombia. In the model, lower tariffs lead importers and exporters to upgrade quality, increasing the domestic demand and...
