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...

"Awareness" for a public good is necessary to stimulate voluntary contributions towards the provision of this commodity. This applies in particular to the global reduction of greenhouse gases and its relevance for mitigation of climate change. The success of the new climate agreement to be...

We consider a model with two countries, two commodities and production factors, labour and environment. The countries first choose their environmental standards and then the equilibrium market allocations are determined. We study a subgame perfect Nash equilibrium of this game for two types of...

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...
