The authors establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws. Individuals born in the beginning of the year start school at an older age, and can therefore drop out after completing less schooling than individuals born near the end of the year. Roughly 25 percent of potential dropouts remain in school because of compulsory schooling laws. They estimate the impact of compulsory schooling on earnings by using quarter of birth as an instrument for education. The instrumental valuables estimate of the return to education is close to the ordinary least squares estimate, suggesting that there is little bias in conventional estimates.

This paper analyzes data on 11,600 students and their teachers who were randomly assigned to different size classes from kindergarten through third grade. Statistical methods are used to adjust for nonrandom attrition and transitions between classes. The main conclusions are (1) on average, performance on standardized tests increases by four percentile points the first year students attend small classes; (2) the test score advantage of students in small classes expands by about one percentile point per year in subsequent years; (3) teacher aides and measured teacher characteristics have little effect; (4) class size has a larger effect for minority students and those on free lunch; (5) Hawthorne effects were unlikely.

This paper uses a unique data set to measure peer effects among college age roommates. Freshman year roommates and dormmates are randomly assigned at Dartmouth College. I find that in this group, peer effects are very important in determining levels of academic effort and in decisions to join social groups such as fraternities. Residential peer effects are markedly absent in other major life decisions such as choice of college major. Several forms of peer effects are considered. The data support a model in which peer effects are driven by roommate behavior after the freshmen arrive. Social learning based on a roommate's observable pre-Dartmouth information or skills appears to be less important. Peer effects in GPA occur at the individual room level whereas peer effects in fraternity membership occur both at the room level and the entire dorm level. I also find that a freshman with high social ability is likely to remain with his or her roommates in sophomore year, but high academic ability actually decreases roommate retention.
The Regulation of Labor [статья]

We investigate the regulation of labor markets through employment, collective relations, and social security laws in 85 countries. We find that the political power of the left is associated with more stringent labor regulations and more generous social security systems, and that socialist, French, and Scandinavian legal origin countries have sharply higher levels of labor regulation than do common law countries. However, the effects of legal origins are larger, and explain more of the variation in regulations, than those of politics. Heavier regulation of labor is associated with lower labor force participation and higher unemployment, especially of the young. These results are most naturally consistent with legal theories, according to which countries have pervasive regulatory styles inherited from the transplantation of legal systems.
