This article presents, through gravity models and a correct definition of what is understood by lost opportunities, an analysis of aggregate trade flows aimed at identifying China’s effects on Latin America’s trade. The results obtained indicate that it is not possible to talk about lost...

We study international trade in a model where consumers have non-homothetic preferences and where household income restricts the extensive margin of consumption. In equilibrium, monopolistic producers set high (low) prices in rich (poor) countries but a threat of parallel trade restricts the...

Empirical evidence shows that R&D spending is highly correlated with firm productivity, highly concentrated among large firms, and responsive to trade liberalization. This paper develops a model of product upgrading with heterogeneous firms that captures these characteristics by allowing firms...

This paper focuses on the necessary conditions required in order to exploit the substitution effect which arises when there is a shift in demand induced by import quotas under imperfect competition. The protective policy succeeds if the substitution effect shifts in favor of goods produced by...

We study international trade in a model where consumers have non-homothetic preferences and where household income restricts the extensive margin of consumption. In equilibrium, monopolistic producers set high (low) prices in rich (poor) countries but a threat of parallel trade restricts the...

Why would an increase in imported inputs rise exports? We argue that importing more varieties of intermediate inputs increases firm’s productivity and thereby makes the firm able to overcome the export fixed costs. Whereas the literature evidences the positive effect of an increase in imported...

Is there evidence from China's pre-WTO accession period that newly imposed U.S. or EU import restrictions deflect Chinese exports to third markets? We examine this question by drawing on a newly constructed data set of U.S. and EU product-level import restrictions on Chinese trade imposed...

This paper addresses the question of why the price of nontradables relative to tradables is positively correlated with income per worker. I construct a two-sector model in which agents differ with respect to managerial ability. Agents sort themselves by choosing to become a worker, a manager in...

A large class of models with CES utility and iceberg trade costs are now known to generate isomorphic “gravity equations.” Economic interpretations of these gravity equations vary in terms of two basic elements: the exporter's “mass” variable and the elasticity of trade with respect to...

This paper endogenizes the extent of intra-sectoral competition in a multi-sectoral general-equilibrium model of oligopoly and trade. Firms choose capacity followed by prices. If the benefits of capacity investment in a given sector are below a threshold level, the sector exhibits Bertrand...
