Social scientists are often interested in assessing relative changes between two groups over time, for example, the convergence of black-white wages from 1940 to 1990. In such situations, we need a control group for both treatment groups to remove biases resulting from time trends and unobserved...

We present a detailed decomposition method and provide a Stata estimator to assess relative changes between two groups over time in a synthetic cohort analysis. Using the convergence of black–white wage gap between 1960 and 1970 as an example, we show that education accounts for 73% of the...

Interviews present a puzzle: Research suggests they are of little value in screening hires, and yet they remain pervasive. Using a longitudinal dataset from a large call center company, we find that interviewers vary in quality along three dimensions of performance: making offers, convincing...

Referrals can impact screening and self-selection of applicants during the hiring process. We model and estimate how referral information affects the selection of employees through job offers, acceptances, and turnover. Using rich data from a call center company, we show that referrals help...
