I don’t agree with lots in this article, but do agree it’s important to highlight that minimum wages can affect other aspects of job quality.
w/ Michael Davies and Jisung Park, I find higher minimum wages increase workplace injuries, likely via work intensification.

For years, governments have made incautious rises to the minimum wage. That has caused economists to fret that wage floors are as high as they should go
Economists get cold feet about high minimum wages
Governments are pushing the policy to its limits

Not quote-skeeting, but I do want to point out that the paper on techno-optimism and climate action being circulated is a pre-print of an observational study which the authors claim shows "effects" based on an incorrect understanding of how quantitative causal inference works.
