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...

A series of observations on various types of cooperatives is constructed from intermittent surveys between 1920 and 1950 and, where possible, these are extended to recent years. These observations allow several questions to be taken up: how well have organizations that resemble consumers'...

This paper considers a matching model of heterogenous workers and jobs which includes onthe-job search. High-educated workers transitorily accept unskilled jobs and continue to search for skilled jobs. We study the implications of this model for the unemployment rates of high and low-educated...

We develop a simple human capital model for optimum schooling length when earnings are stochastic, and highlight the pivotal role of risk attitudes and the schooling gradient of earnings risk. We use Spanish data to document the gradient and to estimate individual response to earnings risk in...
