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...
