The GATT/WTO Article XXIV prevents a customs union (CU) from raising its common external tariff. In this paper, we compare CU formation with and without this Article XXIV constraint. We show, in a multi-country oligopoly model, that for a given CU structure, Article XXIV improves world welfare...

This paper analyses GATT/WTO trade negotiations in an oligopolistic multi-country setting and identifies a new rationale for trade agreements.  When set unilaterally, tariffs are inefficiently high, both for familiar terms-of-trade reasons, but also to restrict market access of foreign firms. ...

We empirically examine the impact of trade on labor demand elasticities using Korean firm-level data. In our analysis, in addition to looking at the impact of liberalizing import restrictions, we take into account the fact that greater trade integration also leads to better and greater export...

This article analyzes European Union-China trade relations in the context of the current negotiations for a new comprehensive framework agreement between the European Union (EU) and the People’s Republic of China. China is a strong economic power with increasingly sophisticated production in...

While the WTO process of multilateral trade liberalization encounters increasing resistance, in part because the most difficult issues have finally risen to the top of the agenda, market-based forces are contributing to international economic integration. One of the most potent are cross-border...
