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'...

Religions often preach preferential treatment of fellow believers, but the magnitude and economic implications of religion-based discrimination are largely unknown, partly because religiosity is often confounded with ethnicity. We analyze grading decisions in national matriculation exams in...

The pay-as-you-go social security system, increasingly burdened by dwindling labor force, can benefit from immigrants whose birth rates exceed those of the native born birth. The paper examines adynamic political-economy mechanism through which the social security system influences the young...

In the political-economy debate people express the idea that immigrants are good because they can help pay for the old, thus help sustaining the social security system. In addition, the median voter whose income derives from wages will wish to keep out the immigrants who will depress his/her...

In the political debate people express the idea that immigrants are good because they can help pay for the old. The paper explores this idea in a dynamic political-economy setup. For this purpose we develop an OLG political economy model of social security and migration. We characterize sub-game...

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...

This paper uses a natural experiment in Israel to assess the impact of school teaching resources and how it is used, ‘time-on-task', on academic achievements and non-cognitive outcomes. It exploits variation induced by a change in the funding formula that reduced instructional resources...
