I examine how globalization affects wages and welfare in a general equilibrium model of international trade with partly oligopolistic markets. Globalization is modeled as reducing trade costs or opening up shielded sectors to trade. There is a national or international common agency that...

We build a model of tacit collusion between firms that operate in multiple markets to study the effects of trade costs. A key feature of the model is that cartel discipline is endogenous. Thus, markets that appear segmented are strategically linked via the incentive compatibility constraint....

Why is further multilateral trade liberalisation proving so difficult to achieve? This paper shows that Article XXIV itself, the set of WTO rules governing trade block formation, undermines the multilateral liberalisation process. Trade block formation under Article XXIV can be thought of as a...

Foreign direct investment (FDI) has grown far more rapidly than trade during the last two decades. As with the other prominent features of globalisation, FDI is controversial. The impact of FDI on labour markets has been of growing concern, particularly, for source countries. The deterioration...

We show in a multi-sector, heterogeneous-firm trade model that the effect of tariffs on entry, especially in the presence of production linkages, can reverse the traditional positive optimal tariff argument. We then use a new tariff dataset, and apply it to a 189-country, 15-sector version of...

In a standard multi-sector, heterogeneous-firm trade model the effect of tariffs on entry, especially in the presence of production linkages, can reverse the traditional positive optimal-tariff argument. We construct and employ a new, large, disaggregated tariff dataset and then apply a...
