Using records from a large public university, we examine the impact of Greek life on academic performance and salaries. To isolate the causal effect of Greek life, we exploit a university policy prohibiting students from joining a Greek organization during their first semester and a minimum GPA for subsequent eligibility. Regression discontinuity and panel methods reveal that Greek affiliation reduces student grades by 0.1-0.3 standard deviations. Greek effects are largest during the semester of pledging, semesters of increased social activities, and for males. We find no evidence of a Greek salary premium and rule out even modest positive effects.

This study uses employment data on California county-industry pairs (CIPs) between 1990 and 2016 to test whether minimum wage increases caused employment growth to slow most in the CIPS with a large share of low wage workers. Evidence supports the hypothesis, and we use the estimates to simulate the effect of a 10 percent increase in the minimum wage. The simulations suggest that a 10 percent increase could cause a 3.4 percent employment loss in the average CIP in California. The job loss is projected to be concentrated in two industries: accommodation and food services, and retail. While the most populated counties of California are expected to incur the largest employment loss in terms of the number of workers, the smaller counties generally experience a larger percentage point loss in employment due to the lower wages and the greater number of workers that would be affected by the minimum wage hike. Moreover, there is substantial variation across counties in terms of the percentage of jobs lost within a given industry.

This study tests whether the employer mandate under the Affordable Care Act (ACA) increased involuntary part-time (IPT) employment. Using data from the Current Population Survey between 1994 and 2014, we find that IPT employment in 2014 was higher than predicted based on economic conditions and the composition of jobs and workers in the labor market. More importantly, using difference-in-difference methods, we find that the increase in the probability of IPT employment since 2010 was greatest in the industries and occupations where workers were most likely to be affected by the mandate. We also show that there has been virtually no change in the probability of IPT employment where the number of workers affected by the mandate was small. We estimate that approximately 1 million additional workers between the ages of 19 and 64 are in IPT employment as a result of the ACA employer mandate.

According to federal law in 2012, employers can take a credit of up to $5.13 for tips received by workers in satisfying the minimum wage requirement of $7.25. This study uses interstate variation in laws regarding tip credits and minimum wages to identify the effects of reducing or eliminating the tip credit on employment and earnings in the U.S. restaurant industry. Using data from the Quarterly Census of Employment and Wages and the Current Population Survey, we find that a reduction in the tip credit increases weekly earnings but reduces employment in the full services restaurant industry and for tipped workers. The results are robust to controls for spatial heterogeneity in employment trends and are supported by a series of falsification tests.

This study argues that the promotion of union goals could have positive, negative, or neutral effects on risk adjusted return performance. Moreover, the union's ability and incentive to use pension assets to promote union goals will vary with the design of the pension. Using panel data on over 36,000 pension plans drawn from IRS Form 5500 filings, we empirically estimate the effects of unions on risk adjusted returns and find that the union effect on performance varies in ways that are consistent with our priors. In particular, unions have the largest negative effect among multi-employer defined contribution plans and the negative effect of unions can be eliminated by a switch to participant direction. Also, we find that unions improve performance for single employer defined contribution plans.

Since 1990, most pension plans have shifted the responsibility for directing pension assets to the employee. This study summarizes some of the possible explanations for this rapid shift toward participant direction and uses IRS Form 5500 data to investigate the effect of worker and plan characteristics on the likelihood of making a switch. The study also estimates the effect of a switch to participant direction on employee contribution and asset allocation behavior. The analysis reveals that collective bargaining and pension investments in employer stock reduce the chance of a switch to participant direction, whereas below average return performance increases the chance. Also, a switch to participant direction increases employee contributions to the pension and reduces the share of assets invested in employer securities.
