In this paper we experimentally investigate whether partial coercion can in combination with conditional cooperation increase contributions to a public good. We are especially interested in the behavior of the non-coerced populations. The main finding is that in our setting conditional...

Solar geoengineering has received increasing attention as an option to temporarily stabilize global temperatures. A key concern surrounding these technologies is that heterogeneous preferences over the optimal amount of cooling combined with low deployment costs may allow the country with the...

We experimentally study the causal effects of different types of market experience on the efficiency levels attained in a subsequent social dilemma. Our motivation stems from the existence of contrasting views on the potential spillover effects of participation in markets on non-market...

We study the stability of voluntary cooperation in response to varying rates at which a group grows. Using a laboratory public-good game with voluntary contributions and economies of scale, we construct a situation in which expanding a group's size yields potential efficiency gains, but only if...

We investigate whether there is a link between conditional cooperation and betrayal aversion. We use a public goods game to classify subjects by type of contribution preference and by belief about the contributions of others; and we measure betrayal aversion for different categories of subject....

Over the last millennium, the clan and the corporation have been the loci of cooperation in China and Europe respectively. This paper examines - analytically and historically - the cultural and institutional co-evolution that led to this bifurcation. We highlight that groups with which...

Since Mancur Olson's “Logic of collective action” it is common conviction in social sciences that in large groups the prospects of a successful organization of collective actions are rather bad. Following Olson's logic, the impact of an individual's costly contribution becomes smaller if the...

An influential body of psychological and anthropological theories holds that societies exhibit heterogeneous cooperation systems that differ both in their level of in-group favoritism and in the tools that they employ to enforce cooperative behavior. According to some of these theories, entire...

What are the long-term effects of Communism on economically relevant notions such as social trust? To answer this question, we use the reunification of Germany as a natural experiment and study the post-reunification trajectory of convergence with regard to individuals’ trust and risk, as well...
