We examine the effects of leading by example in voluntary contributionexperiments. Leadership is implemented by letting one group membercontribute to the public good before followers do. Such leadershipincreases contributions in comparison to the standard voluntary contributionmechanism,...

We present an experimental study on the wasted resources associated with tax evasion. The waste arises from taxpayers and tax authorities, investing costly effort in concealment, respectively detect ion, of tax evasion. We show that (socially ineffcient) efforts depend positively on the...
