Our paper on the minimum wage is in @RevEconStudies! Local #MinimumWage hikes can decrease employment in competitive markets with low labor market concentration but increase employment in markets with high labor market concentration. The result is consistent with #monopsony.

I’m thinking of participating in (or maybe organizing) a workshop on the best ways to change the world and live your life as a tenured professor. It would be in the summer of 2023. Who’s interested? Any thoughts? Is there such a workshop already?

I'm excited to be writing a literature review on #monopsony, & I want to write a helpful one. 1. What are the most important papers in this literature in the past 10 years, and why are they important? 2. Are there some specific questions you'd like me to cover? #EconTwitter
