Viewing individual contributions as investments in emission reduction we rely on the familiar linear public goods-game to set global reduction targets which, if missed, imply that all payoffs are destroyed with a certain probability. Regulation by milestones does not only impose a final...

In generosity games, one agreement payoff is exogenously given, whereas the other is endogenously determined by the proposer's choice of the "pie" size. This has been shown to induce pie choices which are either efficiency or equality seeking. In our experiment, before playing the generosity...

In a situation, where it is efficient for one of two parties to pollute but highly inefficient if both parties do so, the harmed third party can freely impose its damage claims on both parties what crucially determines which equilibrium to expect. Whereas "equality before the law" requires equal...

In two-person generosity games the proposer's agreement payoff is exogenously given whereas that of the responder is endogenously determined by the proposer's choice of the pie size. Earlier results for two-person generosity games show that participants seem to care more for efficiency than for...

We run a market experiment where firms can choose not only their price but also whether to present comparable offers. They are faced with artificial demand from consumers who make mistakes when assessing the net value of products on the market. If some offers are comparable however, some...

There is extensive literature, both theoretical and empirical, on the effects of social identity on a wide range of economic and non-economic outcomes. However, there is only scarce knowledge about how social identity is affected by policies or market structure. We address the question how...

Gender-specific patterns of self-selection into competitive and cooperative environments may have multiple reasons. One of the most prominent explanations to this point is, that there are inherent differences between men and women when it comes to preferences regarding competition. We take a...

Like Feinberg and Sherman (1985) and Phillips and Mason (1992) we test experimentally whether conglomerate firms, i.e., firms competing on multiple structurally unrelated markets, can effectively limit competition. Our more general analysis assumes differentiated rather than homogeneous products...

This paper experimentally investigates the effect of limits on campaign spending and outcome in an electoral contest where two candidates, an incumbent and a challenger, compete for office in terms of the amount of campaign expenditure. The candidates are asymmetric only in that the incumbent...
