D. Diamantaras et al., DECENTRALIZATION OF PARETO OPTIMA IN ECONOMIES WITH PUBLIC PROJECTS, NONESSENTIAL PRIVATE GOODS AND CONVEX COSTS, Economic theory, 8(3), 1996, pp. 555-564
In the theory of economies with public goods one usually considers the
case in which private goods are essential, i.e., each agent receives
a fixed minimum level of utility if he consumes no private goods, irre
spective of the public goods consumed. This paper develops the second
welfare theorem for economies with public projects and possibly inesse
ntial private goods. As a corollary we also derive conditions under wh
ich valuation equilibria exist.
