This paper is a practical guide for researchers and practitioners who want to understand spillover effects in program evaluation. The paper defines spillover effects and discusses why it is important to measure them. It explains how to design a field experiment to measure the average effects of...

Conditional cash transfer (CCT) programs aim to alleviate poverty through monetary and in-kind benefits, as well as reduce future levels of poverty by encouraging investments in education, health, and nutrition. The success of CCT programs at reducing poverty depends on whether, and the extent...

Conditional cash transfer (CCT) programmes aim to alleviate poverty through monetary and in-kind benefits, as well as reduce future incidence of poverty by encouraging investments in education, health and nutrition. The success of CCT programmes at reducing poverty depends on whether, and the...

We estimate the income elasticity for a variety of macro- and micronutrients using a sample of poor rural households in Mexico. The nutrient-income elasticity is estimated using both parametric and semiparametric methods. A special focus is placed on the nonlinearity of the relationship between...

Does research add value to aid? Specifically, does impact evaluation research help or hinder the delivery of development projects? This paper analyzes the question by constructing a new data set of 100 impact evaluations and 1,135 projects appro
