Many of the world's largest cities are now in developing countries. We develop a simple theoretical model, inspired by the case of Mexico, that explains the existence of such giant cities as a consequence of the strong forward and backward linkages that arise when manufacturing tries to serve a...

We develop a model in which special interest groups make political contributions in order to influence an incumbent government's choice of trade policy. In the political equilibrium. the interest groups bid for protection, and each group's offer is optimal given the offers of the others. The...

In this paper we reconsider a key empirical prediction generated by an important class of political-economy models of trade policy, namely that trade protection should be higher in sectors characterized by lower import penetration (we call this the little support for this prediction. In this...

Using the menu-auction approach to endogenous determination of tariffs and allowing additionally for lobby formation itself to be endogenous, this paper analyzes the impact of unilateral trade liberalization by one country on its partner's trade policies. We find that such unilateral...

This paper considers a specific factor model with two sectors in which agents are altruistic towards domestic residents. I show that, even if the degree of altruism is small, direct democracy leads to commercial policies that are biased against trade as long as the mobile factor is unbiased in...

Economists and political scientists have frequently attempted to determine whether trade policy-related political action takes place along factor-lines (such as capital versus labor, as implied by the Stolper-Samuelson theorem) or along industry-lines (as implied by models with imperfect factor...

With fast-track authority (FTA), the US Congress delegates trade-policy authority to the President by committing not to amend a trade agreement. We suggest an interpretation in which Congress uses FTA to forestall destructive competition between its members for protectionist rents. We show that...
