This paper addresses the final steps to global free trade -- the political economy forces that might drive them, and the role the WTO might play in guiding them. Two facts form the departure point: 1) Regionalism is here to stay; 2) the motley assortment of regional trade agreements is not the...

In a model where all factors of production are imperfectly mobile, we argue that the Dixit-Norman scheme of commodity taxes may not lead to strict Pareto gains from trade. Rather, this scheme must be augmented by policies which give factors an incentive to move: hence, the role for trade...

A free trade agreement supports global free trade since trade barriers tend to divert trade in favor of members, but not reduce imports. The term: 'mutual assured deterrence' is used to refer to a regional free trade association that has the feature that no member can gain individually from the...

What is the impact on output of movement towards free trade? Can trade liberalization have a permanent effect on output levels, and more importantly, does it have an impact on steady-state growth rates? The model developed here emphasizes the role" that knowledge spillovers emanating from...

This paper asks why developing country policymakers have been so reluctant to undertake trade reform until the 1980s, and why many of them have embraced open trade policies so wholeheartedly since then. To answer these questions, the paper develops a heuristic index of the "political...

Quantitative results from a large class of structural gravity models of international trade depend critically on the elasticity of trade with respect to trade frictions. We develop a new simulated method of moments estimator to estimate this elasticity from disaggregate price and trade-flow data...

The new trade theory emphasizes the role of market-share reallocations across firms ("stealing") in driving productivity growth, while the older literature focused on average productivity improvements ("learning"). We use comprehensive, firm-level data from India's organized manufacturing sector...

This paper reviews a new framework for analyzing the interrelationship between inequality, unemployment, labor market frictions, and foreign trade. This framework emphasizes firm heterogeneity and search and matching frictions in labor markets. It implies that the opening of trade may raise...

Recent trade models determine the equilibrium distribution of firm-level efficiency endogenously and show that freer trade shifts the distribution towards higher average productivity due to entry and exit of firms. These models ignore the possibility that freer trade also alters the firm-size...

Unilateral tariff liberalisation by developing nations is pervasive but our understanding of it is shallow. This paper strives to partly redress this lacuna on the theory side by introducing three novel political economy mechanisms with particular emphasis is on the role of production...
