In recent years, interest has been growing in policy applications of different auction systems. This paper reports a series of experiments that were used to design and implement an auction in a unique policymaking environment. In April 2000, the Georgia legislature passed a law that mandated...

The use of monetary incentives may not affect behavior much in some contexts, or it may simply reduce the dispersion of data around some theoretical prediction. But the experiments indicate that incentive effects may be large and systematic in other contexts. In the absence of a widely accepted...

Public goods experiments are notable in that they produce an array of systematic treatment effects that are inconsistent with the predictions of standard game theory. In response, theorists have proposed alternative models designed to explain these interesting (and often intuitive) patterns in...

The standard public goods experiment involves linear payoffs in which the unique Nash equilibrium is at the lower boundary, i.e., full free riding. Contributions in these experiments tend to decline toward the Nash equilibrium in most treatments, but contributions persist even after as many as...
