ECONOMIES WITH PUBLIC PROJECTS: EFFICIENCY AND DECENTRALIZATION∗

The article deals with the two fundamental theorems of welfare economics for production economies with a finite set of agents, infinitely many private goods, and a set of public projects. The problem of efficiency and decentralization is addressed under the following very general assumptions: (a) the commodity– price duality is endowed with a consistent locally convex topology; (b) the set of public projects is without any mathematical structure. Moreover, any agent is characterized by a nonordered preference relation depending on consumption goods and public projects. Approximate and exact welfare theorems are discussed throughout the article.
