A conservative critic of government programs has written, "Governments know how to do one thing well. They know how to create shortages and surpluses." Explain this quotation using examples like the minimum wage or interest-rate ceilings. Show graphically that if the demand for unskilled workers is price-elastic, a minimum wage will decrease the total earnings (wage times quantity demanded of labor) of unskilled workers.

Key Concepts

Government Intervention

Government intervention in markets involves using policy tools to alter the natural equilibrium of supply and demand. This can take the form of regulations or mandates like price floors or ceilings, which are intended to achieve social or economic goals, but may also lead to unintended consequences such as shortages or surpluses.

Price Controls

Price controls are regulatory measures set by the government to cap or set a price for a good or service. Examples include price ceilings, which set a maximum allowable price, often leading to shortages, and price floors, such as the minimum wage, which set a minimum allowable price, often causing surpluses. These controls disrupt the balance of supply and demand, leading to inefficiencies in the market.

Minimum Wage as a Price Floor

A minimum wage is a classic example of a price floor in the labor market. It is designed to ensure workers receive a baseline level of income. However, if set above the market equilibrium wage, it may result in reduced employment opportunities because the higher wage can lead employers to hire fewer workers, potentially causing a surplus of labor, or unemployment, among unskilled workers.

Price Elasticity of Labor Demand

Price elasticity of demand measures how sensitive the quantity demanded is to a change in price. In the context of labor, if the demand for unskilled workers is highly elastic, an increase in wages (due to a minimum wage) will lead to a proportionally larger reduction in the number of workers employed. This means that even though the wage per worker is higher, the significant drop in employment can lower overall earnings for the group.

Total Earnings

Total earnings in the labor market are calculated as the product of the wage rate and the quantity of labor employed. When a minimum wage is imposed in a market where the demand for labor is elastic, the decrease in employment can be so substantial that even with a higher wage, total earnings (wage multiplied by the reduced quantity of labor) for unskilled workers decline, illustrating a counterproductive outcome of the policy.
