Tax and expenditure policies are studied in a federation with mperfectly mobile households. States implement a linear progressive tax and supply a public good. A vertical fiscal externality, reflecting the effect of the state policies on federal revenues, provides an incentive to state taxes to...

In a dynamic general equilibrium setup, this paper highlights the role of vintages and creative destruction in business fluctuations. By stressing the forward-looking characteristic of the optimal scrapping rule, we use a standard rational expectations argument to show the constancy of the...

We provide a definition of the rational expectations core in an atomless economy with asset markets and show that allocations in the core can be decentralized by a system of asset and spot prices as rational expectations equilibria.

This paper proposes a model where employers have two types of prejudices: racial and spatial discrimination. Because of the first one, black workers have less chance than white workers to find a job. Because of the second one, workers living closer to the city-center have less chances than...

This paper dels with optimal taxation in a two-class economy with two private commodities and labour. We derive optimal non-linear income and linear commodity taxes in the presence of merit goods. We formulate merit goods arguments via pathology of individual choice. We assume weak separability...
