Leadership is important for the well-functioning of organizations. We examine the effects of leadership on contributions in public goods experiments. Leadership by example is implemented by letting one group member contribute to the public good before followers do. Such leadership increases...

We investigate experimentally whether entry costs have an impact on the evolution of cooperation in a social dilemma game. In particular, subjects repeatedly play the so-called takeover game with anonymous partners randomly drawn from a fixed population of participants. The game represents a...

The variable threat-bargaining model of Nash (1953) assumes that threats in the sense of binding commitments as to what one will do if bargaining ends in conflict, are chosen before bargaining. By comparision, late threats to be chosen after bargaining end in conflict, appear more natural and...

In a large scale newspaper experiment 5,132 readers of the German weekly, Die Zeit, participated in a three-person bargaining game. In our data analysis we focus on (1) the influence of age, gender, profession and the medium chosen for participation on bargaining behavior and on (2) the external...

In the experiment two bureaucrats independently can grant a permit with the profit of the private party depending on when the permit is given. Whereas one bureaucrat can only veto the project, the second one has additional discretion in granting the permit earlier or later. We speak of greasing...

We study a market in which both buyers and sellers can decide to preempt and set their quantities before market clearing. Will this lead to preemption on both sides of the market, only one side of the market, or to no preemption at all? We find that preemption tends to be asymmetric in the sense...

In a stochastic duopoly market, sellers must form state-specific aspirations expressing how much they want to earn given their expectations about the other's behavior. We define individually and mutually satisficing sales behavior for given individual beliefs and aspiration profiles. In a first...

Idiosyncratic risk attitudes are usually assumed to be commonly known and restricted to own payoffs. However, the alternatives faced by a decision maker often involve risks for others' payoffs as well. Motivated by the importance of other-regarding preferences in social interactions, this paper...

We examine the effects of leading by example in voluntary contribution experiments. Leadership is implemented by letting one group member contribute to the public good before followers do. Such leadership increases contributions in comparison to the standard voluntary contribution mechanism,...
