The Gains from Input Trade with Heterogeneous Importers

Dynamic Selection and the New Gains from Trade with Heterogeneous Firms∗

This paper develops an open economy growth model in which firm heterogeneity increases the gains from trade. Technology spillovers from incumbent firms to entrants cause the productivity threshold for firm survival to grow over time as competition becomes tougher. By raising the profits of exporters, trade increases the entry rate and generates a dynamic selection effect that leads to higher gr...

Measurable Dynamic Gains from Trade

Volatility, Insurance, and the Gains from Trade∗

By reducing the negative correlation between local prices and productivity shocks, trade liberalization changes the volatility of returns. In the context of agriculture in developing countries—where production is risky, producers are risk averse, and insurance markets are incomplete—this change in volatility may have large welfare effects. In this paper, we empirically, analytically, and quanti...

Transboundary Pollution and the Gains from Trade

We analyse the effects of transboundary pollution on trade patterns and welfare in a general equilibrium trade model. Production in a dirty industry generates pollution that negatively effects productivity, both at home and abroad, in a clean industry. Trade may lead to the spatial separation of production but the existence of transboundary pollution can offset the benefits from specialization....

European Integration and the Gains from Trade

This chapter discusses whether and how 'new quantitative trade models' (NQTMs) can be fruitfully applied to quantify the welfare effects of trade liberalization, thus shedding light on the trade-related effects of further European integration. On the one hand, it argues that NQTMs have indeed the potential of being used to supplement traditional ‘computable general equilibrium’ (CGE) analysis t...
