摘要：Social networks are important for finding jobs, but which ties are most useful? Granovetter has suggested that weak ties are more valuable than strong ties, since strong ties have redundant information, while weak ties have new information. Using 6 million Facebook users' data, we find evidence for the opposite. We proxy for job help by identifying people who eventually work with a pre-existing friend. Using objective tie strength measures and our job help proxy, we find that most people are h...

摘要：While a large literature has focused on the impact of parental investments on child cognitive development, very little is known about the role of the child's own investments alongside that of the parents. By using the Child Development Supplement of the Panel Study of Income Dynamics, we model the cognitive production function for adolescents using an augmented value-added model and adopt an estimation method that takes account of unobserved child characteristics. We find that a child's own in...

摘要：This paper analyzes the US Lanham Act of 1940, a heavily subsidized and universal child care program administered during World War II. I first estimate its impact on maternal employment using a triple-differences model. I find that employment increased substantially following the introduction of the program. I then study children's long-run labor market outcomes. Using Census data from 1970 to 1990, I assess well-being in a life-cycle framework by tracking cohorts of treated individuals throug...

摘要：This paper estimates peer effects in a university context where students are randomly assigned to sections. While students benefit from better peers on average, low-achieving students are harmed by high-achieving peers. Analyzing students' course evaluations suggests that peer effects are driven by improved group interaction rather than adjustments in teachers' behavior or students' effort. Building on Angrist's research, we further show that classical measurement error in a setting where grou...

摘要：We investigate the impact of local social pressure on firms' firing decisions. Using linked employer-employee data, we show that secondary establishments located further away from headquarters have higher dismissal rates than those located closer. The effect of distance on dismissals is stronger, the greater the visibility of the firm in the local community of its headquarters and the larger the degree of selfishness of that community. We show that these findings can be explained by the social...

摘要：We investigate how workers' performance is affected by the timing of wages in a real-effort experiment. In all treatments, agents earn the same wage sum, but wage increases are distributed differently over time. We find that agents work harder under increasing wage profiles if they do not know these profiles in advance. A profile that continuously increases wages by small amounts raises performance by about 15% relative to a constant wage. The effort reactions can be organized by a model in wh...

摘要：Algorithmically recommending workers to employers for the purpose of recruiting can substantially increase hiring: in an experiment conducted in an online labor market, employers with technical job vacancies that received recruiting recommendations had a 20% higher fill rate compared to the control. There is no evidence that the treatment crowded out hiring of nonrecommended candidates. The experimentally induced recruits were highly positively selected and were statistically indistinguishable...
