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...

Although a growing theoretical literature points to credit constraints asan important source of inefficiently high child labor, little work has been done to assess its empirical relevance. Using panel data from Tanzania, the authors find that households respond to transitory income shocks by...

Using four rounds of panel household data from the Kagera region of Tanzania, we show that transitory income shocks ¨C measured by the value of crop lost by farming households ¨C lead to significantly increased child labor. A one standard deviation increase in the shock is associated with a...

This paper examines the relationship between child labor and access to credit at a crosscountry level. Even though this link is theoretically central to child labor, so far there has been little work done to assess its importance empirically. We measure child labor as a country aggregate, and...
