AbstractWe analyze the impact of high youth minimum wages, relying on two decades of linked employer–employee data and a major law change. Alternative treatment/control groups follow from two strands of the literature, one tracking low‐skilled workers employed before the law change, who are eligible for a large wage increase, and one tracking the employment of full cohorts, whether working or in school when the law changed. High minimum wages led to a short‐term wage gain, which faded over time. They did not jeopardize employment prospects. Changes in the hours worked by part‐time workers point to increased job attachment.
