This paper examines a model of an infinite production economy with a finite number of types of agents and semi-public goods, which are subjected to crowding and exclusion. The utility of an agent depends not only on the vector of public commodities produced by the coalition to which she belongs,...

This paper examines a model of an infinite production economy with a finite number of types of agents and semi-public goods, where utility of a member of a coalition depends not only on the vector of public commodities produced by this coalition, but also on the structure of the coalition. The...

This paper investigates efficiency and equitability issues given a cost sharing method f in an economy with a public commodity. We introduce the basic concept of a f-Lindahl equilibrium and study the set of all these particular equilibrium allocations. It then turns out that this set is...

The central result of this paper is a refinement of an equivalence theorem in Mas-Colell (1980) for the core of a finite economy with a public good. It is shown that an allocation belongs to the core if and only if it is a cost share equilibrium. A further characterization of core elements which...
