paper examines the labor market effects of Florida’s 2022 post-tenure review policy, which weakened tenure protections at public universities. Using a differencein-differences approach, we compare faculty outcomes in Florida to nearby states. We find the policy increased faculty exits-particularly among high-performing researchers-indicating a brain drain rather than improved selection. Additionally, we detect no productivity gains among incumbents and observe a decline in the research output of new hires. Overall, the findings suggest that reducing tenure protections negatively affects the research capacity and competitiveness of public universities.
