Optimal Voting Rules

We study dominant strategy incentive compatible (DIC) and deterministic mechanisms in a social choice setting with several alternatives. The agents are privately informed about their preferences, and have single-crossing utility functions. Monetary transfers are not feasible. We use an equivalence between deterministic, DIC mechanisms and generalized median voter schemes to construct the constrained-efficient, optimal mechanism for an utilitarian planner. Optimal schemes for other welfare criteria such as, say, a Rawlsian maximin can be analogously obtained

Dominant Strategies Implementation when Compensations are Allowed:a Characterization Fundación

Dominant strategies truthful implementation of flexible social objectives involves the ability of the planner to alter the individual incentives in such a way that the externality imposed on society by each agent reporting a given type is fully internalized in the agent’s final payoff. In other words, the agents’ objective function must mimic the social objectives. We find that our main result is robust enough to explain why well-known mechanisms like Groves’s transfers work in some contexts while some other social objectives are not implementable in dominant strategies.Individual decisiveness, compensation mechanisms, dominant strategies.
