Evidence from an experiment investigating the “house money effect” in the context of a public goods game is reconsidered. Analysis is performed within the framework of the panel hurdle model, in which subjects are assumed to be one of two types: free-riders, and potential contributors. The...

In this paper, an economy is analyzed where one group of agents, the altruists, cares about the well-being of another group of agents, the recipients. It is asked how changes in the size of these groups affect the altruists’ charitable giving in the Nash equilibrium. I show that a pure group...

In a laboratory experiment, I test whether guilt aversion, i.e., a preference to fulfill other people’s expectations, plays out stronger if agents are socially close. I induce two different group identities among participants. They play a dictator game. Dictators either play with a recipient...

In the dictator game, the recipient’s opportunity to send a message to the dictator increases giving. The effect is equally strong if the message is written before or after the dictator has decided (experiment 1). Recipients have a stronger willingness to pay for ex-ante communication, however...

This article reports the results of a simple bargaining experiment on the ultimatum-revenge game. The game enables to differentiate between fairness that is stimulated by intentional based motives, distributional motives, and fairness considerations that mix both motives. The laboratory...

In this paper we investigate the role of judicial control of lobbying activities in an endogenous policy framework, focusing on two dimensions of quality of the judiciary, namely efficiency and integrity. We present a multi-layer lobbying model where a self-interested group is allowed to inuence...

In 1878 the liberal parties lost enough votes to loose the majority in the parliament which they had defended in the general election just one year before. In this paper, the question of where the voters came from and why the voting changed so crucially within one year are re-examined. The...

We study the effect of voting when insiders’ public goods provision may affect passive outsiders. Without voting insiders’ contributions do not differ, regardless of whether outsiders are positively or negatively affected or even unaffected. Voting on the recommended contribution level...

According to Adam Smith (1790), human selfishness can be restrained by introspection. We test the effect of introspection on people’s willingness to cooperate in a public good game. Drawing on the concept of identity utility (George A. Akerlof and Rachel E. Kranton, 2000), we show...

Punishees regularly ask for justification. But is justification also effective? To answer this question under controlled conditions, we have conducted a public goods experiment with central punishment. The authority is neutral – she does not benefit from contributions to the public good....
