We show that a minimum wage may either increase or decrease hours per worker and the change will have the opposite sign to the slope of the equilibrium hours hourly wage locus. Similarly, total hours worked may rise or fall. We illustrate the results throughout with a Cobb-Douglas example.enThis is the author’s version of a work that was accepted for publication in Labour Economics.
