We provide simple tests for selection on unobserved variables in the Vytlacil-Imbens-Angrist framework for Local Average Treatment Effects. The tests allow researchers not only to test for selection on either or both of the treated and untreated outcomes, but also to assess the magnitude of the...

We analyze the impact on crime of 3.7 million refugees who entered and stayed in Turkey as a result of the civil war in Syria. Using a novel administrative data source on the flow of offense records to prosecutors' offices in 81 provinces of the country each year, and utilizing the staggered...

This paper investigates the effects of application processing times on welfare applicants' benefit and employment outcomes. For causal inference, we exploit exogenous variation in application processing times stemming from the random assignment of caseworkers. Our findings indicate that longer...

In this paper I seek to identify and estimate the causal effect of fertility on family income. I analyze the endogeneity of the decision to have a second child with a sample of twins at first birth (as in Rosenzweig and Wolpin, 1980). And the decision to have a third son is addressed with an...

This chapter considers methods for evaluating the impact of social programs in the presence of nonrandom program placement or program selection. It first presents the evaluation problem as a missing data problem and then considers various solutions proposed in the statistics and econometrics...
