In the Solidarity Game (Selten and Ockenfels, 1998) lucky winners of a lottery can transfer part of their income to unlucky losers. Will losers get smaller transfers if they can be assumed to be (partly) responsible for their zero income because they have chosen riskier lotteries (Trhal and...

The launch of a public project requires support from enough members of a group. Members (players) are differently important for the project and have different cost/benefit relations. There are players who profit and players who suffer from the launch of the project. Examples are the Kyoto...

In this paper we propose a three-level computational equilibrium model that allows to analyze the impact of the regulatory environment on transmission line expansion (by the regulator) and investment in generation capacity (by private firms) in liberalized electricity markets. The basic model...

We experimentally investigate a Bertrand market with homogenous goods where sellers may behave socially responsible by donating a share of their profits to an existing non-profit organization. In our experiment, we find that this Corporate Social Responsibility (CSR) component is used...

Empirische Studien weisen darauf hin, dass der Gender Wage Gap - die geschlechtsspezifische Lohnlücke - im Tarifbereich geringer als im nicht-tarifgebundenen Bereich der Wirtschaft ausfällt. Dennoch ist es eine weitgehend offene Frage, wie sich die Strukturen und der Ablauf von...

In this paper we propose a three-level computational equilibrium model that allows to analyze the impact of the regulatory environment on transmission line expansion (by the regulator) and investment in generation capacity (by private firms) in liberalized electricity markets. The basic model...

In liberalized electricity markets strategic firms compete in an environment characterized by fluctuating demand and non-storability of electricity. While spot market design under those conditions by now is well understood, a rigorous analysis of investment incentives is still missing. Existing...

Public goods provision often involves groups of contributors repeatedly interacting with administrators who can extract rents from the pool of contributions. We suggest a novel identification approach that exploits the sequential ordering of decisions in a panel vector autoregressive model to...

In this study, we investigate how and why people discriminate among different groups, including their own groups and multiple out-groups. In a laboratory experiment, we use dictator games for five groups to compare actual transfers to in-group and out-group agents with the respective beliefs...

We conduct an experimental study among European citizens regarding cross-cultural perceptions related to trust in two dimensions: volunteerism and honesty. We use representative samples from five major economies of the Euro area: France, Germany, Italy, the Netherlands, and Spain. We find that...
