This paper investigates the role of social learning in the diffusion of a new agricultural technology in Ghana. We use unique data on farmers communication patterns to define each individual s information neighborhood, the set of others from whom he might learn. Our empirical strategy is to test...

In this chapter we examine social networks among farmers in a developing country. We use detailed data on economic activities and social interactions between people living in four study villages in Ghana. It is clear that economic development in this region is being shaped by the networks of...

We look at the effects of rainfall forecasts and realized rainfall on equilibrium agricultural wages over the course of the agricultural production cycle. We show theoretically that a forecast of good weather can lower wages in the planting stage, by lowering ex ante out-migration, and can...

Many basic economic theories with perfectly functioning markets do not predict the existence of the vast number of microenterprises readily observed across the world. We put forward a model that illuminates why financial and managerial capital constraints may impede experimentation, and thus...

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 this paper we argue the case for greater exploitation of synergies between research on specific institutions based on micro-data and the big questions posed by the institutions and growth literature. To date, the macroeconomic literature on institutions and growth has largely relied on...

We examine the impact of ambiguous and contested land rights on investment and productivity in agricultural in Akwapim, Ghana. We show that individuals who hold powerful positions in a local political hierarchy have more secure tenure rights, and that as a consequence they invest more in land...

We show that the real return to capital in Ghana’s informal sector is high. For farmers, we find annual returns ranging from 205-350% in the new technology of pineapple cultivation, and 30- 50% in well-established food crop cultivation. We also examine the relative prices of durable goods of...
