Market exchange is subject to an endogenously determined level of predation which impedes specialization and gains from trade. We construct a model in which utility-maximizing agents opt between careers in production and careers in predation. Three types of equilibria may emerge: autarky (with...

A simple general equilibrium model of an economy with distortionary taxes and public goods is used to extend, unify and clean up the welfare analysis of changes in taxation, redistribution and the provision of public goods. We clarify the distinction between compensation and money metric...

There is widespread concern about the effect of the Uruguay Round policy changes on world agricultural prices and consequently upon the welfare of developing countries. Assessing welfare changes with the standard terms of trade effect calculation can be misleading for distorted economies, since...

The theory of trade reform typically is based on a passive government budget constraint, in which changes in tariff revenue are costlessly offset by lump sum transfers. This paper offers a general framework for trade reform when the government budget constraint is active, such that tariff...

"Contract enforcement is probabilistic, but the probability depends on rules and processes. A stimulus to trade may induce traders to alter rules or processes to improve enforcement. In the model of this paper, such a positive knock-on effect occurs when the elasticity of supply of traders is...

"Most empirical policy work requires the aggregation of policies. Trade policy aggregation exemplifies the aggregation problem poignantly, with thousands of highly dispersed trade barriers. This paper provides methods of policy aggregation that are consistent with two common objectives of...

Government budget balance forces the endogenous use of distortionary tax instruments" when an exogenous reform is implemented. The aggregate efficiency of such reforms is based" on comparisons of simple summary measures of the Marginal Cost of Funds of the various tariff" or quota changes with...
