Several economists have maintained that social sanctions can enforce cooperation in public good situations. This experimental study investigates whether indirect social sanctions from monetarily unaffected observers can increase contributions to a public good. The experiment has two treatment...

Studies have shown that there are differences in cooperative behavior across countries. Furthermore, differences in the use of and the reaction to the introduction of a norm enforcement mechanism have recently been documented in cross-cultural studies. We present data that prove that stark...

A collective decision problem is described by a set of agents, a profile of single-peaked preferences over the real line and a number k of public facilities to be located. We consider public facilities that do not suffer from congestion and are non-excludable. We provide a characterization of...

This paper presents the results from an experiment investigating whether framing affects the elicitation and predictive power of preferences for cooperation, i.e., the willingness to cooperate with others. Cooperation preferences are elicited in three treatments using the method of Fischbacher,...

We examine a global refunding scheme for mitigating climate change. Countries pay an initial fee into a global fund that is invested in long-run assets. In each period, part of the fund is distributed among the participating countries in relation to the emission reductions they have achieved in...

We analyze non-cooperative international climate policy in a setting of political competition by national interest groups. In the first stage, countries decide whether to set up an international emission permits market, which only forms if it is supported by all countries. In the second stage,...

This paper examines the investment incentives of market-based regulation, with focus on the technology characteristics the different regulatory schemes tend to incentivize. The firms' technology choice is socially optimal if and only if the aggregate emission allowance supply is completely...

In this paper we provide a political game where agents decide whether to become legislators or politicians. Legislators determine the political institutions constraining politicians\' behavior and politicians compete for gaining the power to make decisions about the level of the public good. We...

Using a natural experiment from Germany, we show that temporary placebased subsidies generate persistent effects on economic density. We identify employment and capital formation as main channels for higher income per square kilometer. As the spatial regression discontinuity design allows us to...

In addition to his role as a consumer pursuing his own interests, an individual may also regard himself as an ethical observer, judging matters from society's point of view. It is not clear which of these possibly conflicting roles respondents in contingent valuation studies take on. This leads...
