Map of berlin for In the case of the minimum wage, the equilibrium wage is considered to be too low for workers to live on. Consequently, governments enact price floors in labor markets despite the fact that they may contribute to market inefficiencies (i.e., unemployment). The reverse is true in the case of rent control in which the equilibrium price is considered to be too high for prospective tenants to afford. Governments, as a result, establish price ceilings in these cases despite the fact that they create a shortage of quality apartments. [Editor’s Note: Since price ceilings and floors cause shortages and surpluses, it is therefore necessary that the government provide additional jobs of last resort, as in the case of minimum wage, and be willing to build additional housing units, as in the case of rent control, to enable the markets to clear.
