The investment decisions of small-scale farmers in developing countries are conditioned by their financial environment. Binding credit market constraints and incomplete insurance can reduce investment in activities with high expected profits. We conducted several experiments in northern Ghana in...

We partnered with a micro-lender in Mali to randomize credit offers at the village level. Then, in no-loan control villages, we gave cash grants to randomly selected households. These grants led to higher agricultural investments and profits, thus showing that liquidity constraints bind with...

In an experiment providing fertilizer grants to women rice farmers in Mali, we found that women who received fertilizer increased both the quantity of fertilizer they used on their plots and complementary inputs such as herbicides and hired labor. This highlights that farmers respond to an...

While the regulation of tenancy arrangements is widespread in the developing world, evidence on how such regulation influences the long-run allocation of land and labor remains limited. To provide such evidence, this paper exploits quasi-random assignment of linguistically similar areas to...

The aim of this paper is to provide a new mechanism based on social interactions explaining why minority workers have worse labor-market outcomes than majority workers. Building on Granovetter's idea that weak ties are superior to strong ties for providing support in getting a job, we develop a...

Evidence from psychology suggests that overconfidence is more important in North America than in Japan. The pattern is reversed for shame, an emotion that appears to play a more important role among Japanese than North Americans. We develop a model that endogenizes these differences, building on...

We study how the prevailing internal organization of the family affected the initial design of pension systems. Our theoretical framework predicts that, in society with weak family ties, pensions systems were introduced to act as a safety net, while in societies with strong ties they replicate...

We develop two different social network models with different economic foundations. In the local-aggregate model, it is the sum of friends' efforts in some activity that affects the utility of each individual while, in the local-average model, it is costly to deviate from the average effort of...

We consider a linguistically diversified society that has to select a set of official languages. We examine the notion of language disenfranchisement that is created when one or more languages fail to be included in the list of the official ones, implying that some individuals are denied full...

Many people are sensitive to social esteem, and their pride is a source of pro--social behavior. We present a game-theoretic model in which sensitivity to esteem varies across players and may depend on context as well players' beliefs about their opponents. For example, the pride associated with...
