Individuals of high type can perform both skilled and unskilled jobs, but only a fraction of low\u2010type workers can perform skilled jobs. People have different costs over these jobs. First, we calibrate the model to match U.S. CPS time series since the 1980s. To control for unobserved heterogeneity, we compute wages based on workers who have switched between skilled and unskilled jobs. We show that changes in educational mismatch has contributed one\u2010sixth as much as skilled\u2010bias technological progress for the rise in the college premium. Second, we calibrate the model to match moments of the 50 United States, to measure the output costs of frictions generating mismatch. The cost of frictions is 0.26% of output on average but varies between 0.06% to 0.77% across states. The key variable that explains the output cost of vertical mismatch is not the percentage of mismatched workers but their wage relative to well\u2010matched workers.<\/jats:p>","DOI":"10.3982\/qe1868","type":"journal-article","created":{"date-parts":[[2025,6,11]],"date-time":"2025-06-11T06:57:46Z","timestamp":1749625066000},"page":"535-564","source":"Crossref","is-referenced-by-count":6,"title":["Economic
