Being good-looking seems to generate substantial benefits in many social interactions, making the "beauty premium" a not to be underrated economic factor. This paper investigates how physical attractiveness enables people to generate these benefits in the case of cooperation, using field data...

We study how the willingness to enter long-term bilateral relationships affects cooperation even when parties have little information about each other, ex ante, and cooperation is otherwise unenforceable. We experimentally investigate a finitely-repeated Prisoner’s Dilemma, allowing players to...

Centralized sanctioning institutions are of utmost importance for overcoming free-riding tendencies and enforcing outcomes that maximize group welfare in social dilemma situations. However, little is known about how such institutions come into existence. In this paper we investigate, both...

We analyze the dynamics of neighbourhood watch programs in a local interaction framework. Agents can watch their neighbours' houses and thus deter burglars from breaking in. At the same time, agents also try to recruit their neighbours to join the neighbourhood watch program. The probability of...

This paper provides a survey of recent experimental work in eco- nomics focussing on social and economic networks.The experiments consider networks of coordination and cooperation,buyer-seller net- works,and network formation.

Costless pre-play communication has been found to effectively facilitate coordination and enhance efficiency in games with Pareto-ranked equilibria. We report an experiment in which two groups compete in a weakest-link contest by expending costly efforts. Allowing intra-group communication leads...

Schott et al. (2007) have shown that the “tragedy of the commons” can be overcome when individuals share their output equally in groups of optimal size and there is no communication. In this paper we investigate the impact of introducing communication groups that may or may not be linked to...

Opinion is divided on whether it is better to have a single world money or variable exchange rates. Pope, Selten and von Hagen (2003) propose that fresh light would be shed via an analysis that allows for seven complexity impacts on the exchange rate that are underplayed (where not entirely...

We study how cooperative behavior reacts to selective (favorable or unfavorable) pre-play information about the cooperativeness of other, unrelated groups within an experimental framework that is sufficiently rich for conflicting behavioral norms to emerge. We find that cooperation crucially...
