This paper discusses the nonparametric identification of causal direct and indirect effects of a binary treatment based on instrumental variables. We identify the indirect effect, which operates through a mediator (i.e. intermediate variable) that is situated on the causal path between the...

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...

Smallholder agriculture in Sub-Saharan Africa is largely exposed to pervasive market failures, translating into missed opportunities and sub-optimal economic behavior. These failures can partly be traced to the importance of economies of scale in procuring inputs and marketing produce, where...

This study analyses whether the Swedish school choice reform, enacted in 1992, had different effects on students from different socio-economic backgrounds. We use detailed geographical data on students' and schools' locations to construct measures of the degree of potential choice. This allows...

Aktive Arbeitsmarktpolitik in der Schweiz wird der deutschen gegenübergestellt. Beide Länder haben viele Gemeinsamkeiten bezüglich Zielsetzung, Instrumenten und institutionellen Reformen von aktiver Arbeitsmarktpolitik. In der Schweiz stand jedoch bereits schon früher eine informative...

We examine the effectiveness of three democratically chosen rules that alleviate the coordination and cooperation problems inherent in collectively managed common-pool resources. In particular we investigate how rule effectiveness and rule compliance depends on the prevailing local norms and...

This paper evaluates the effects of a major Swedish school choice reform. The reform in 1992 increased school choice and competition among public schools as well as through a large-scale introduction of private schools. We estimate the effects of school choice and competition, using precise...
