We outline a new voting procedure for representative democracies. This procedure should be used for important decisions only and consists of two voting rounds: a randomly-selected subset of the citizens is awarded a one-time voting right. The parliament also votes, and the two decisions are...

We consider the problem of choosing a level of the public good for an economy in which agents have continuous and single-peaked preferences (Black, 1948). We show that a solution satisfying strategy-proofness and continuity if and only if it is an augmented median-voter solution. An augmented...

In a recent paper, Sprumont (1991) showed that the uniform rule (Benassy, 1982) on the single-peaked domain (Black, 1948) is the only rule that satisfies strategy-proofness, anonymity, and efficiency. This result motivates us to investigate whether there is a larger domain on which there exists...

The Qualified Majority Voting (QMV) used by the Council of the European Union developed to a high degree of complexity from one modifying treaty to another, until the latest definition stipulated in the Treaty of Lisbon. This paper analyses this EU intra-institutional voting method using a...

Research on collective provision of private goods has focused on distributional considerations. This paper studies a class of problems of decision under uncertainty in which an efficiency argument for collective choice emerges from the mathematics of aggregating individual payoffs. Consider...

The problem of how to rationally aggregate probability measures occurs in particular (i) when a group of agents, each holding probabilistic beliefs, needs to rationalise a collective decision on the basis of a single 'aggregate belief system' and (ii) when an individual whose belief system is...

Standard models of equilibrium unemployment assume exogenous labour market institutions and flexible wage determination. This paper models wage rigidity and collective bargaining endogenously, when workers differ by observable skill and may adopt either individualised or collective wage...

We study the nature of individual demands for environmental regulation and for trade openness in the general equilibrium of a small open economy where the environment is an input to production. Differences in the ability of individuals to afford private mitigation of the adverse consequences of...
