A recent literature has developed that combines two prominent empirical approaches to ex ante policy evaluation: randomized controlled trials (RCT) and structural estimation. The RCT provides a "gold-standard'' estimate of a particular treatment, but only of that treatment. Structural estimation...

Section I introduces the material. In section II a model is developed which explores the impact of input-quality uncertainty on factor demand from which is derived a rationale for the use of devices which segment the population into classes differing in their "skill" distribution parameters. The...

This paper seeks to explain the U-shaped relationship between farm productivity and farm scale - the initial fall in productivity as farm size increases from its lowest levels and the continuous upward trajectory as scale increases after a threshold - observed across the world and in low-income...

Parochial politics is typically associated with poor leadership and low levels of public good provision. This paper explores the possibility that community involvement in politics need not necessarily worsen governance and, indeed, can be efficiency-enhancing when the context is appropriate....

Obesity is an important global health problem. Although obesity is not directly related to access to health care or constrained by resource deprivation, overweight status is predominantly found in poor, less-educated populations. This paper seeks to identify the causal role of schooling in...

The livelihoods of the majority of the world's poor depend on agriculture. They face substantial risk from fluctuations in weather conditions. Better risk, credit and savings markets can improve productivity and welfare in rural areas but entail high administrative costs. We consider a classic...

We exploit recent molecular genetics evidence on the genetic basis of arsenic excretion and unique information on family links among respondents living in different environments from a large panel survey within a theoretical framework incorporating optimizing behavior to uncover the hidden costs...

We examine the role of ethnic politics at the local level in supplying public goods within a framework that incorporates two sides to ethnic groups: an inclusionary side associated with internal cooperation and an exclusionary side associated with the disregard for others. The inclusionary...

We use unique data characterizing individual savings for twins and non-twins in urban China to examine why the savings rates of the young are elevated relative to the middle-aged, despite rising individual life-cycle incomes. We show that inter-generational co-residence masks the true life-cycle...

We examine the generalizability of internally valid estimates of causal effects in a fixed population over time when that population is subject to aggregate shocks. This temporal external validity is shown to depend upon the distribution of the aggregate shocks and the interaction between these...
