This paper focuses on indivisible multiple-cost–single-benefit projects that must be approved by the government. A simple mechanism is proposed that ensures an efficient and fair implementation of such projects. The proposed mechanism is appropriate for a unilateral information structure: the...

In this paper we develop a differentiable approach to deal with incentives in a, possibly small, subset of a general domain of preferences in economies with one public and one private good. We show that, for two agents, there is no mechanism which is efficient, strategy-proof and where...

This chapter examines the scope for mutually beneficial intergenerational cooperation, and looks at various attempts to theoretically explain the emergence of norms and institutions that facilitate this cooperation. The contributions reviewed come from branches of economics as far apart as...
