Experimental studies have shown that sanctions effectively deter free riding within groups. However, the over-use of costly punishment may actually harm overall welfare. A main reason for over-punishment is that free-riders generate negative emotions that likely favor excessive punishments. In this paper we ask whether the venting of one’s emotions in different ways can reduce the level of exce...

One goal of federal housing policy is to improve the prospects of children in poor families. This paper examines the effect of public housing participation on housing quality and educational attainment. Using the SIPP, we show that living in projects is associated with more negative outcomes for children, although this appears to be due to unobserved heterogeneity. We control for the endogeneit...

We present a model of altruistically-minded– yet rational– players contributing to a public good. A key feature is the tension between altruism and crowding-out effects. We present three main results: (1) More altruistic behaviour often reduces social welfare; (2) It is almost always optimal for a player to act more selfishly than her true preference; (3) A player’s optimal altruistic commitmen...

We explore the effect of fixed versus dynamic group membership on public good provision. In a novel experimental design, we modify the traditional voluntary contribution mechanism (VCM) by periodically replacing old members of a group with new members over time. Under this dynamic, overlapping generations matching protocol we find that average contributions experience significantly less decay o...
