In this paper we study the optimal import policy in an oligopolistic market with a given number of quantity-setting firms. In the absence of fixed costs, we show that if the policy instrument is an import quota, the optimal policy is either free trade or autarky, while if the instrument is a tariff the optimal policy is neither free trade nor autarky. In the case of fixed costs, we show that co...

This paper shows that governments have no incentive to introduce non-tariff barriers when they are free to set tariffs but they do when tariffs are determined cooperatively. We then show three results. First, with trade liberalization, there is a progression from using tariffs only to quotas, and to antidumping constraints (when quotas are jointly eliminated). Second, there is a narrowing of th...

States with weak institutions can lose from trade with strong states when trade is subject to predation. The happy liberal idea of trade fostering better institutions and peace can be turned on its head. The Ricardian model of trade subject to predation offered here implies imperialism without capital, contra Marxists. Weak and poor South trades with strong and rich North. Poor South labor is a...

In practice, Free Trade Agreements (FTAs) vastly outnumber Customs Unions (CUs). Nevertheless, the literature traditionally views CUs as optimal for members because CU members coordinate external tariffs. I show that a dynamic FTA flexibility benefit can help explain the prevalence of FTAs: individual FTA members have the flexibility to form their own future FTAs whereas CU members must jointly...

We investigate the extent to which antidumping actions eliminate trade altogether. Using quarterly 10-digit HS-level export data for products involved in U.S. antidumping cases we find that antidumping actions increase the hazard rate by more than 50%. We find strong evidence of investigation effects with the impact during the initiation and preliminary duty phases considerably larger than once...

This paper shows that an importing country can have an incentive to impose a tari to extract rents earned by foreign exporters even in a perfectly competitive setting. To demonstrate this, I develop a new model of international trade that incorporates xed costs of exporting and rm heterogeneity within a perfectly competitive framework. In this setting, despite the fact that there are no pre-exi...

This paper examines the welfare implications of an existence of free trade agreements (FTAs) and customs unions (CUs) in the GATT system, in the presence of cross-foreign ownership among countries. In particular, two GATT regimes are analyzed: a pure GATT regime without any regional free trade agreements, and modified GATT regime with either an FTA or a CU. This paper argues that, when foreign ...

The world’s largest retailers—Walmart, Carrefour, Tesco, and Metro—all entered China after 1995. They established hundreds of stores as well as centers for procuring goods to be sold worldwide. Multinational retailers may affect Chinese exports through two channels. First, they could inform outlets in other countries where they operate about the products offered by local Chinese suppliers, ther...
