This paper investigates the effects of environmental conditions during pregnancy on later life outcomes using quasi-experimental variation created by the immigration of Ethiopian Jews to Israel in May 24th 1991. Children in utero prior to immigration faced dramatic differences in medical care...

The consequences of gender social and learning interactions in the classroom are of interest to parents, policy makers, and researchers. However, little is known about gender peer effects in schools and their operational channels. In this paper, we estimate the effects of classroom gender...

In this paper, we estimate the extent of ability peer effects in the classroom and explore the underlying mechanisms through which these peer effects operate. We identify as low ability students those who are enrolled at least one year behind their birth cohort (quot;repeatersquot;). We show...

There is renewed interest in ways to enhance secondary education, especially among disadvantaged students. This study evaluates the short-term effects of a remedial-education program that provided additional instruction to under-performing high-school students in Israel. The program targeted...

This paper measures empirically the relationship between classroom teaching practices and student achievements. Based on primary- and middle-school data from Israel, I find very strong evidence that two important elements of teaching practices cause student achievements to improve. In...

This paper studies the effect of mothers' education on fertility in a population with very low female labor force participation. The results we present are particularly relevant to many countries in the Muslim world where 70-80 percent of women are still out of the labor force. For...

The time that children spend in school varies across countries. Do these differences explain international gaps in pupils' academic achievements? In this paper, I estimate the effects of instructional time on students' achievement using PISA 2006 data, which includes data samples from over 50...

This paper uses an unusual pay reform to test the responsiveness of investment in schooling to changes in redistribution schemes that increase the rate of return to education. We exploit an episode where different Israeli kibbutzim shifted from equal sharing to productivity-based wages in...

In this paper, we estimate the influence of social relationships on educational attainment and social outcomes of students in school. More specifically, we investigate how losing different types of social relationships during the transition from elementary to middle school affect students'...
