This paper reviews empirical methods used to estimate the impact of trade policies under imperfect competition. We decompose the welfare effects of trade policy into four possible channels: (i) a deadweight loss from distorting consumption and production decisions; (ii) a possible gain from...

Do trade reforms that significantly reduce import barriers lead to faster economic growth? In the two decades since Rodríguez and Rodrik's (2000) critical survey of empirical work on this question, new research has tried to overcome the various methodological problems that have plagued previous...

This paper presents a non-technical discussion of economic issues that arise due to links between competition (or anti-trust) policy and international trade. While recent advances in international trade theory have borrowed heavily from the industrial organization literature, this work has a...

The last two centuries witnessed the rise and fall of empires. We construct a model which rationalises this in terms of the changing trade gains from empires. In the model, empires are arrangements that reduce trade cost between an industrial metropole and the agricultural periphery. During...

When subsidies and tariffs are applied to imports with fluctuating prices, it is shown that the output response of domestic producers depends on market structure and their attitude toward risk. The domestic industry response is contrasted under two types of market structure, a monopoly and a...

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...

We study a simple, tractable model of labor adjustment in a trade model that allows us to analyze the economy's dynamic response to trade liberalization. Since it is a neoclassical market-clearing model, we can use duality techniques to study the equilibrium, and despite its simplicity a rich...

This chapter (to appear in the forthcoming Handbook of International Economics, Vol. 5) develops a framework with which to interpret and survey answers to the question: how does increased openness affect aggregate welfare in a typical developing country? We decompose answers into four...

A model is constructed in which multinational firms may arise endogenously. Multinationals exist in equilibrium when transport and tariff costs are high, incomes are high, and firm-level scale economies are important relative to plant-level scale economies. Less obvious, multinationals are more...
