The effect of shift structure on worker performance and productivity is of increasing interest to firms and regulatory bodies. Using approximately 743,000 emergency medical incidents attended by 2,381 paramedics in Mississippi, we evaluate the extent that paramedics' performance toward the end...

The returns to educational investments hinge on whether such investments can improve the quality and persistence of educational gains. We report the results from a randomized evaluation of an adult education program in Niger, in which some students learned how to use simple mobile phones...

Almost 50 years after domestic US family planning programs began, their effects on childbearing remain controversial. Using the county-level roll-out of these programs from 1964 to 1973, this paper reevaluates their shorter and longer term effects on US fertility rates. I find that the...

We assess the implications of nonlinearity for IV and FE estimation when the estimated model is inappropriately assumed to be linear. Our application is the causal link between family income and child outcomes. Our nonlinear IV and FE estimates show an increasing, concave relationship between...
