We examine the role of intergenerational co-residence for female labour supply in a patrilocal society. To account for the endogeneity of women's co-residence with parents or in-laws, we exploit a tradition in Central Asia, namely that the youngest son of a family usually lives with his parents....

We present robust evidence on the presence of adverse selection in hospitalization insurance for low-income households. A large randomized control trial from Pakistan allows us to separate adverse selection from moral hazard, to estimate how selection changes at different points of the demand...

Child labor is a common consequence of economic shocks in developing countries. We show how reducing vulnerability can affect child labor and schooling. We exploit the extension of a health and accident insurance scheme by a Pakistani microfinance institution (MFI) that was set up as a...

Trust is crucial for successful collective action. A prime example is collective commercialization of agricultural produce through producer organizations. We conduct a cluster-randomized controlled trial in rural Senegal in which we vary the number and the type of smallholder farmers – members...

We analyze whether the availability of formal insurance products affects informal solidarity transfers in two independent behavioral experiments in the Philippines. The first experiment allows for communication, non-anonymity and unrestricted transfers. The second experiment mimics a laboratory...

We measure the willingness to compete of entrepreneurs and salaried workers in an experiment. We let participants choose between a piece-rate and a tournament scheme either in private or in public. We find that in the private condition entrepreneurs are less competitive than salaried workers,...

We devise a new experimental game by nesting a voluntary contributions mechanism in a broader spectrum of incentive schemes. With it, we study tensions between egalitarianism, equity concerns, self-interest, and the need for incentives. In a 2x2 design, subjects either vote on or exogenously...

Recent research has shown that women shy away from competition more often than men. We evaluate experimentally three alternative policy interventions to promote women in competitions: Quotas, Preferential Treatment, and Repetition of the Competition unless a critical number of female winners is...
