Consider a perfectly competitive labor market. Labor demand and supply are $L^D = 140 - 4w$ $L^S = -10 + w$ Where L is the number of workers and w is the wage. In the perfectly competitive equilibrium, the wage is w*= and the number of workers with a job is L*= . Now suppose that the government introduces a minimum wage of $32. In this case, firms would be willing to hire workers, and there would be workers willing to work at this wage.
