By the way: the ban is retroactive and has penalties built in for violators. It goes into effect June 2027, when WA will join CA, OK, MN, and ND as states that prohibit more or less all noncompetes.

Noncompetes are a bit less in the news than a year or two ago. But WA just quietly banned ALL employee noncompetes. Previously, they had been banned for relatively low paid workers only governor.wa.gov/news/2026/go...

How does employer access to prisoners’ labor through work release impact the well-being of those workers & of free workers? New working paper by Sue Helper, Suresh Naidu, Akseli Palomaki, Adam Reich, + me provides evidence, focus on auto manufacturing in AL #EconSky papers.ssrn.com/sol3/papers....
Coercion and Monopsony in Modern American Manufacturing: Evidence from Alabama Prison Labor
Susan Helper Suresh Naidu Akseli Palomaki Adam Reich
Aaron Sojourner

We study coercion and monopsony in contemporary U.S. manufacturing labor markets. We combine administrative data from the Alabama Department of Corrections work release program with a unique survey of workers in the Alabama auto supply chain
where workers report their work-release status. We first present descriptive patterns of work-release labor, finding that the use of incarcerated (i.e., work-release) labor is concentrated in the auto supply industry, especially in the Montgomery area, where
Hyundai’s assembly plant is located. In the survey, the share of plant-level workers who are incarcerated is negatively correlated with non-incarcerated wages. The survey also enables estimation of hypothetical quit elasticities separately among incarcerated
and non-incarcerated workers. Incarcerated workers are estimated to have quit elasticities less than half that of non-incarcerated workers. Because Alabama law requires employers to pay the same wage to incarcerated and non-incarcerated workers in the same jobs, the additional monopsony power introduced by employer access to incarcerated workers creates an incentive and ability for employers to reduce plant-level wages to, and employment of, non-incarcerated workers. We build a quantitative model of firm-specific labor supply that, for incarcerated workers, distinguishes the roles of coercion (the risk of physical harm in prison from not working), wage garnishment that blunts the consumption effect of higher wages, and monopsony (limited mobility across employers). Using it, we estimate effects on free and incarcerated workers’ welfare from i) reforming prison conditions to eliminate violence, ii) eliminating prison labor wage
garnishment, iii) imposing a $15 minimum wage, &iv) abolishing prison labor. Free worker welfare goes up in all scenarios...

I've been interested in this question for a while now. It's really one that could go either way: does the increase in competition or the greater ability to tacitly collude dominate? Great to see strong evidence. I'm sure this is a topic we'll learn a lot more about in coming years
