Trade policy reforms in recent decades have sharply reduced the distortions that were harming agriculture in developing countries, yet global trade in farm products continues to be far more distorted than trade in nonfarm goods. Those distortions reduce some forms of poverty and inequality but...

This paper analyses the welfare effects of changes in cross-sectional wage dispersion, using a class of tractable heterogeneous-agent economies. We emphasize a trade-off in the welfare calculation that arises when labour supply is endogenous. On the one hand, as wage uncertainty rises, so does...

This paper studies an overlapping generations model with stochastic production and incomplete markets to assess whether the introduction of an unfunded social security system leads to a Pareto improvement. When returns to capital and wages are imperfectly correlated a system that endows retired...

We develop a multi-country Dixit-Stiglitz model to investigate the impacts of: (i) changes in the international distribution of consumers' expenditure; (ii) decreasing tariffs; and (iii) improvements in transportation infrastructure. We show that, in general, decreasing tariff barriers do not...

This paper employs MIMIC, an applied general equilibrium model of the Dutch economy, to explore various tax cuts aimed at combating unemployment and raising labour supply. MIMIC combines modern labour-market theories, a firm empirical foundation, and a detailed description of Dutch labour-market...

International negotiations for an agreement to reduce the emission of greenhouse gases are unlikely to produce concrete and comprehensive policies for effective emission reductions in the near term, not least because the policy measures being considered are economically very costly to major...

This paper presents a computable general equilibrium model of world trade, and applies the model to analyses of world trade and production effects of European integration. The main features of the model are: four world regions, twelve traded goods, one non-tradable aggregate in each region and...

We develop a method that allows one to compute incomplete-market equilibria routinely for Markovian equilibria (when they exist). The main difficulty to be overcome arises from the set of state variables. There are, of course, exogenous state variables driving the economy but, in an incomplete...

China has always strived for self-sufficiency in farm products, particularly staple foods. Its rapid industrialization following its opening up to global markets during the past two decades has been making that more difficult, and its accession to the WTO may add to that difficulty. New...

Using a numerical general equilibrium model we examine the possible production, trade and welfare effects of successful implementation of the Uruguay Round results. The model includes trade in manufactures and (some) services among industrial regions and countries; there is imperfect competition...
