This paper considers causal inference and sample selection bias in nonexperimental settings in which (i) few units in the nonexperimental comparison group are comparable to the treatment units, and (ii) selecting a subset of comparison units similar to the treatment units is difficult because...

This paper considers causal inference and sample selection bias in non-experimental settings in which: (i) few units in the non-experimental comparison group are comparable to the treatment units; and (ii) selecting a subset of comparison units similar to the treatment units is difficult because...

This paper uses propensity score methods to address the question: how well can an observational study estimate the treatment impact of a program? Using data from Lalonde's (1986) influential evaluation of non-experimental methods, we demonstrate that propensity score methods succeed in...

This paper describes a general equilibrium based social policy model for Cote d'Ivoire whose aim is both to facilitate analysis of a wide range of social policy options, any of which could conceivablybe pursued in Cote d'Ivoire over the next five or ten years, and to provide a basis for further...

This paper uses data from the Greater Avenues for Independence (GAIN) demonstration to discuss the evaluation of programs that are implemented at multiple sites. Two frequently used methods are pooling the data or using fixed effects (an extreme version of which estimates separate models for...

Even though access to credit is central to child labor theoretically, little work has been done to assess its importance empirically. Dehejia and Gatti examine the link between access to credit and child labor at a cross-country level. The authors measure child labor as a country aggregate, and...

This paper exploits a unique longitudinal data set from Tanzania to examine the consequences of child labor on education, employment choices, and marital status over a 10-year horizon. Shocks to crop production and rainfall are used as instrumental variables for child labor. For boys, the...
