This paper estimates the effect of the early childhood environment on a large array of social and economic outcomes lasting almost 60 years. To do this, we exploit variation in the living conditions experienced by Yemenite children after being airlifted to Israel in 1949. We find that children...

We use simulation methods to impute missing data. First we suggest how one can iteratively estimate a large number of parameters associated with a joint normal distribution function fof latent variable associated with the data. We suggest a way to test the joint normality assumption next....

We present in this paper evidence about the effects and mechanisms of gender peer effects in elementary, middle, and high schools. For identification, we rely on idiosyncratic variations in gender composition across adjacent cohorts within the same schools. We find that an increase in the...

The Israeli matriculation certificate is a prerequisite for most postsecondary schooling. In a randomized trial, we attempted to increase certification rates among low-achievers with cash incentives. The experiment used a school-based randomization design offering awards to all who passed their...

This article presents evidence on the child-quantity/child-quality trade-off using quasi-experimental variation due to twin births and preferences for a mixed sibling sex composition, as well as ethnic differences in the effects of these variables. Our sample includes groups with very high...
