We study the gains from trade in an economy with oligopolistic competition, firm heterogeneity, and innovation. Oligopolistic competition together with free entry make markups responsive to firm productivity and trade costs. Lowering trade costs reduces markups on domestic sales but increases...

For developing countries, a technological catch-up is sometimes a prerequisite for endorsement of trade agreements. This paper compares sequential trade liberalization through a preferential trade agreement (PTA) and one-shot multilateral trade liberalization with respect to the speed with which...

The recent extensive study of vertical product differentiation models has allowed for the analysis of international trade issues in the presence of country asymmetries in terms of product qualities, technology, costs, market size and income. In the presence of such asymmetries, national...

We study the gains from trade in a model with oligopolistic competition, heterogeneous firms and innovation, and provide a formula to decompose the mechanism. The new insight we provide is that market concentration can be a welfare-relevant feature of market power above and beyond markup...

This paper presents a dynamic general equilibrium model of trade between two advanced countries in which both innovation and skill acquisition rates are endogenously determined. The model offers a North-North (as opposed to a North-South) trade explanation for increasing relative wage...

This paper analyzes the economic effects of TBT under the existence of technological asymmetry between countries. It first defines TBTs and shows the current status and evolution of TBTs using descriptive measures. In addition, the paper also compares the technology levels of Korea to those of...

The COVID-19 pandemic has accelerated the shift toward digital services. Meanwhile, the race for technological and economic leadership has heated up, with risks of decoupling that could set back trade and growth and hinder the recovery from the worst global recession since the Great Depression....

This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...

The dynamics of export market exit and firm closure have found limited attention in the new heterogeneous-firms trade literature. In fact, several of the predictions on firm survival and exit stemming from this new class of models are at odds with the stylized facts. Empirically, higher...
