We study a contract change for tea pluckers on an Indian plantation, with a higher government-stipulated baseline wage. Incentive piece rates were lowered or kept unchanged. Yet, in the following month, output increased by 20–80%. This response contradicts the standard model and several...

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...

Agricultural productivity in Sub-Saharan Africa (SSA) lags far behind all other regions of the world. A long list of policy experiments has yielded more evidence on what fails than on what works. We analyze a randomized control trial of a rare scaled-up success story: One Acre Fund's small...

In discussing the paradoxical violation of expected utility theory that now bears his name, Maurice Allais noted that individuals tend to “greatly value” payoffs that are certain. Allais' observation would seem to imply that people will undervalue insurance relative to the predictions of...

In this paper we show that the study of the farm size-productivity relationship hinges on the choice of productivity measure. Our main insight is that using yields, a partial measure of productivity, may not be informative for the size-productivity relationship because, in addition to total...

We examine whether returns to capital are higher for farmers who borrow than for those who do not, a direct implication of many credit market models. We measure the difference in returns through a two-stage loan and grant experiment. We find large positive investment responses and returns to...

Recent evaluations of traditional microfinance loans have found no significant impacts on borrower incomes or productive activities. We examine whether this can be remedied by (a) modifying loan features to facilitate financing of working capital needs of farmers, and (b) delegating selection of...

Many rural households in low and middle income countries continue to rely on small-scale agriculture as their primary source of income. In the absence of irrigation, income arrives only once or twice per year, and has to cover consumption and input needs until the subsequent harvest. We develop...
