Die Theorie des Wettbewerbs als Entdeckungsverfahren behauptet, daß die Ergebnisse des Wettbewerbes nicht vorhergesagt werden können, weil hierzu Tatsachen benötigt würden, die durch ihn erst entdeckt werden sollen. Dann wäre es allerdings unmöglich, Aussagen über Wettbewerb empirisch zu...

What is the motivational effect of imposing a minimum effort require- ment? Agents may no longer exert voluntary effort but merely meet the requirement. Here, we examine how such hidden costs of control change when control is considered legitimate. We study a principal- agent model where control...

Lying to participants offers an experimenter the enticing prospect ofmaking others' behaviour a controlled variable,but is eschewed by experimental economists because it may pollute thepool of subjects. This paper proposes andimplements a new experimental design, the Conditional...

We evaluate the impact of technology adoption subsidies on in- vestment behavior in an individual choice experiment. In a laboratory setting professional managers are confronted with an intertemporal decision problem in which they have to decide whether or not to search for, and possibly adopt,...

There is a general presumption that social preferences can be ignored if markets are competitive. Market experiments (Smith 1962) and recent theoretical results (Dufwenberg et al. 2008) suggest that competition forces people to behave as if they were purely self-interested. We qualify this view....

When workers are faced with the threat of unemployment, their relationship with a particular firm becomes valuable. As a result, a worker may comply with the terms of a relational contract that demands high effort even when performance is not enforceable by a third party. But can relational...

One possible conclusion from recent experimental research on decision making under risk is that observed behaviour can be reasonable accommodated by expected utility plus an error term. This conclusion implies that the violation rate of expected utility should decrease if errors are excluded....

We show experimentally that a principal?s distrust in the voluntary performance of an agent has a negative impact on the agent?s motivation to perform well. Before the agent chooses his performance, the principal in our experiment decides whether he wants to restrict the agents? choice set by...

Substantial academic interest and public policy debate centers on campaign finance reform. Campaign resources can provide benefits to constituencies if candidates use them to fund the distribution of useful information. On the other hand, voters can potentially be harmed if candidates trade...

In our model, an agent produces an outcome by a costly effort and then distributes it among heterogeneous users. The agent's payoff is the weighted sum of the users? shares and the coefficient reflecting their heterogeneity. When the agent neglects users? heterogeneity the game leads to an...
