We introduce intention-based social preferences into a mechanism design framework with independent private values and quasilinear payoffs. For the case where the designer has no information about the intensity of social preferences, we provide conditions under which mechanisms which have been designed under the assumption that agents are selfish can still be implemented. For the case where precise information about social preferences is available, we show that any tension between efficiency, incentive-compatibility, and voluntary participation may disappear. Impossibility results such as the one by Myerson and Satterthwaite (1983) are then turned into possibility results. We also provide a systematic account of the welfare implications of kindness sensations.

We study political competition in an environment in which voters have private information about their preferences. Our framework covers models of income taxation, public-goods provision or publicly provided private goods. Politicians are vote-share-maximizers. They can propose any policy that is resource-feasible and incentive-compatible. They can also offer special favors to subsets of the electorate. We prove two main results. First, in a symmetric equilibrium, policies are surplus-maximizing and hence first-best Pareto-efficient. Second, there is a surplus-maximizing policy that wins a majority against any welfare-maximizing policy. Thus, in our model, policies that trade off equity and efficiency considerations are politically infeasible.

Terms of use: Documents in EconStor may Robust Mechanism Design and Social Preferences AbstractWe study a classic mechanism design problem: How to organize trade between two privately informed parties. We characterize an optimal mechanism under selfish preferences and present experimental evidence that, under such a mechanism, a non-negligible fraction of individuals deviates from the intended behavior. We show that this can be explained by models of social preferences and introduce the notion of a social-preference-robust mechanism. We characterize an optimal mechanism in this class and present experimental evidence that it successfully controls behavior. We finally show that this mechanism is more profitable only if deviations from selfish behavior are sufficiently frequent.JEL-Code: C920, D030, D820.

Tax competition between two governments who choose nonlinear income tax schedules to maximize the average utility of its residents when skills are unobservable and labor is perfectly mobile is examined. We show that there are no Nash equilibria in which there is a skill type that pays positive taxes to one country and whose utility is larger than the average utility in the other country or in which the lowest skilled are subsidized. We also show that it is possible for the most highly skilled to receive a net transfer funded by taxes on lower skilled individuals in equilibrium. These findings confirm the race-to-the-bottom thesis in this setting. Terms of use: Documents in EconStor mayJEL-Code: D820, H210, H870.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
