The existence of punishment opportunities has been shown to cause efficiency in public goods experiments to increase …

We use experiments to study the efficiency effects for a market as a whole of adding the possibility of forward …

patterns of behavior. Using controlled laboratory experiments, we study how financial incentives can be used to find a way out … of such performance traps. Our experiments are set in a corporate environment where subjects' payoffs depend on …

We study manager-employee interactions in experiments set in a corporate environment where payoffs depend on employees …

examine the sensitivity of this result to the ability of people to observe others' choices. Our experiments are set in a …

theoretical model a dominant and a dominated region first interact through a voting process that can lead to different degrees of …-perfect equilibrium the voting process always leads to an intermediate arrangement acceptable for both parts. Hence, the costly political … struggle never occurs. In contrast, in our experiments we observe a large amount of fighting involving high material losses …
