When properly implemented, Randomized Controlled Trials (RCT) can achieve a high degree of internal validity. Yet, if an RCT is to inform policy interventions that extend beyond the experimental population, it is critical to establish external validity. In this paper, we first present a...

When properly implemented, Randomized Controlled Trials (RCT) achieve a high degree of internal validity. Yet, if an RCT is to inform policy, it is critical to establish external validity. This paper systematically reviews all RCTs conducted in developing countries and published in leading...

This paper provides a survey of six widely used non-experimental methods for estimating the impact of programmes in the context of developing economies (instrumental variables, regression discontinuity, direct matching, propensity score matching, linear regression and non-parametric methods, and...

In most national education systems, educational attainment depends heavily on parental socioeconomic status, which challenges the notion of equal opportunity. Educational interventions have increasingly become the focus of public and scientific debate as a tool for mitigating these disparities....

This paper proposes a powerful alternative to the t-test of the null hypothesis that a coefficient in linear regression is equal to zero when a regressor is mismeasured. We assume there are two contaminated measurements of the regressor of interest. We allow the two measurement errors to be...
