In the above graph, W and L is the equilibrium wage and labor employed respectively
When a minimum wage of Wm is imposed above the equilibrium wage,then it is a price floor which will cause the labor demanded to decrease to Ld and labor supplied to increase to Ls so there exist a surplus in the market because quantity supplied of labor is greater than quantity demanded.
the area denoted by letter C = consumer surplus
letter P = producer surplus
Potential loss from job search = Ls-Ld that is the surplus created as Ls is the labor supplied who are willing to work but Ld is the demanded which will be employed at the given minimum wage so it creates unemployment.
letter DWL = deadweight loss
