We conduct a contest experiment where participants can invest in increasing both the mean and the spread of an uncertain performance variable. Subjects are treated with different prize schemes and in accordance with theory we observe substantial investments in spread. We find that both types of...

We conduct a contest experiment to study if spread seeking and effort can be managed in a situation where participants can invest in increasing both the mean and the spread of an uncertain performance variable. Subjects are treated with different prize schemes and in accordance with theory, we...

When affirmative action policies target more than one disadvantaged group, they contain uncertainty as to whether an individual who belongs to one of these groups was actually favored. In a laboratory experiment, we study how this feature affects outcomes of affirmative action in the form of...

This paper analyzes the coordination challenge a partial cartel faces when payoff asymmetries between potential cartel insiders and potential cartel outsiders are large. We introduce two experimental treatments: a standard treatment where a complete cartel can be supported in a Nash equilibrium...

Public goods are dealt with in two literatures that neglect each other. Mechanism design advises a social planner that expects individuals to misrepresent their valuations. Experiments study the provision of the good when preferences might be non-standard. We introduce the problem of the...

This paper tests motivational crowding out in the domain of charitable giving. A novelty is that our experiment isolates alternative explanations for the decline of giving such as strategic considerations of decision makers. Moreover, preference elicitation allows us to focus on the reaction of...

This paper provides experimental evidence on the formation of partial cartels with endogenous coordination. Firms face a coordination challenge when a partial cartel is to be formed as every firm is better off if it is not inside the cartel but is a free-riding outsider. We introduce a...

Unlike previous attempts to implement cooperation in a prisoners' dilemma game with an infinite horizon in the laboratory, we focus on extended prisoners' dilemma games in which a second (pure strategy) equilibrium allows for voluntary cooperation in all but the last round. Our four main...
