Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...

Labor Market Intermediaries (LMIs) are entities or institutions that interpose themselves between workers and firms to facilitate, inform, or regulate how workers are matched to firms, how work is accomplished, and how conflicts are resolved. This paper offers a conceptual foundation for...

We explore the role of social capital in the spread of the recent Covid-19 pandemic in independent analyses for Austria, Germany, Italy, the Netherlands, Sweden, Switzerland and the UK.

Many of our most pressing challenges, from combating climate change to dealing with pandemics, are collective action problems: situations in which individual and collective interests conflict with each other. In such situations people face a dilemma about making individually costly but...

This paper demonstrates the effects of ethnic and religious diversity on the quality of public spaces. Its identification strategy relies on the exogeneity of public housing allocations in France, and thereby eliminates the bias from endogenous sorting. The paper uses micro evidence of social...

This paper looks at the financial resources of trades unions in the UK, both updating previous work and attempting to understand the management of first and second order collective action problems. First order problems refer to the problems of initiating collective action and second order...
