In this paper we consider a labor constrained scheduling problem (LCSP) which is a simplification of a practical problem arising in industry. Jobs are subject to precedence constraints and have specified processing times. Moreover, for each job the labor requirements varies as the job is...

In a model where agents have unequal production skills and different preferences, we build social welfare functions which rely only on ordinal non-comparable information on individual preferences. Social welfare functions are required to satisfy properties of compensation for inequalities in...

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.
