This paper provides a methodology to study coalition formation problems with externalities and heterogeneous players, whensome subset of the players can act as "coalition developers" over time. The framework provided here allows to explicitly predict the timing of admission to coalitions, the...

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.
