Social norms permeate society across a wide range of issues and are important to understanding how societies function. In this paper we concentrate on 'bad' social norms - those that are inefficient or even damaging to a group. This paper explains how bad social norms evolve and persist; our...

This note uncovers new properties of the von Neumann-Morgenstern solution in weak tournaments and majoritarian games. We propose a new procedure for the construction of choice sets from weak tournaments, based on dynamic stability criteria. The idea is to analyze dynamic versions of the...

We study electoral competition among politicians who are heterogeneous both in competence and in how much they care about (what they perceive as) the public interest relative to the private rents from being in office. We show that politicians may have stronger incentives to behave...

We examine the effects of social preferences and beliefs about the social preferences of others in a simple leader-follower voluntary contributions game. We find that groups perform best when led by those who are reciprocally oriented. Part of the effect can be explained by a false consensus...

We report an experiment comparing sequential and simultaneous contributions to a public good in a quasi-linear two-person setting. In one parameterization we find that overall provision is lower under sequential than simultaneous contributions, as predicted, but the distribution of contributions...

We examine the characteristics of effective leaders in a simple leader-follower voluntary contributions game. We focus on two factors: the individual's cooperativeness and the individual's beliefs about the cooperativeness of others. We find that groups perform best when led by those who are...

We compare social preference and social norm based explanations for peer effects in a three-person gift-exchange game experiment. In the experiment a principal pays a wage to each of two agents, who then make effort choices sequentially. In our baseline treatment we observe that the second...

Governments, central banks, and private organizations frequently face the challenge of convincing their audience to take a specific action. One key choice is whether to send a public message that can coordinate the audience's actions or to rely instead on private messages that may differ across...

Sellers in real-estate markets, on internet platforms, in auction houses, and so forth, routinely pose non-binding price requests. Using a laboratory experiment, we examine how competition moderates the way such cheap-talk communication affects trade between buyers and sellers. For bilateral...
