We study the effects of leadership on the private provision of a public good when group members are heterogeneously endowed. Leadership is implemented as a sequential public goods game where one group member contributes first and all the others follow. Our results show that the presence of a leader increases average contribution levels but less so than in case of homogeneous endowments. Leadership is almost ineffective, though, if participants do not know the distribution of endowments. Granting the leaders exclusion power does not lead to significantly higher contributions.

We report on an experiment designed to explore the interrelation of otherregarding concerns with attitudes towards risk and delay when the latter have a social dimension, i.e., pertain to one's own and another person's payoffs. For this sake, we compare evaluations of several prospects, each of which allocates either certain or risky and either immediate or delayed payoffs to the actor and to another participant. We find that individuals are mainly self-oriented as to social allocation of risk and delay, although they are other-regarding with respect to expected payoff levels.
