To evaluate peer-comparison audit and feedback to high-prescribing primary care physicians (PCPs) and assess the effect of targeted messaging on avoiding unnecessary antibiotic prescriptions and avoiding long-duration prescribing. In this 3-arm randomized clinical trial, administrative data collected from IQVIA's Xponent database were used to recruit the highest quartile of antibiotic-prescribing PCPs (n = 3500) in Ontario, Canada. Physicians were randomized 331 to receive a mailed letter sent in December 2018 addressing antibiotic treatment initiation (n = 1500), a letter addressing prescribing duration (n = 1500), or no letter (control; n = 500). Outliers at the 99th percentile at baseline for each arm were excluded from analysis. The primary outcome was total number of antibiotic prescriptions over 12 months postintervention. Secondary outcomes were number of prolonged-duration prescriptions (&gfeedback, including messaging on limiting antibiotic-prescribing durations, led to statistically significant reductions in total and prolonged-duration antibiotic prescriptions, as well as drug costs. ClinicalTrials.gov Identifier NCT03776383. ClinicalTrials.gov Identifier NCT03776383.Several countries in sub-Saharan Africa, including Kenya, have introduced free/subsidized secondary education. This paper examines the role of these free/subsidized education policies on teenage motherhood. To identify the causal effect, I exploit the timing of a national reform in Kenya that eliminated/subsidized secondary school fees using a difference-in-difference estimation design. Using the 2014 Kenya Demographic and Health Survey (DHS), I estimate that the likelihood of teenage motherhood decreased by approximately 5 percentage points after the policy's implementation. This study reiterates that the te
