4.12: Wage Rigidity and Unemployment I

Wage rigidity refers to the observation that wages cannot be easily adjusted downwards. This means that labor market cannot clear at the equilibrium wage.

Minimum wages are government-imposed wage floors—legal requirements that employers must pay eligible workers at least a certain hourly rate. Minimum wage laws protect low-income workers from exploitation and help to ensure a minimum standard of living.

However, when the minimum wage is set above the market equilibrium, it can create unemployment because the quantity of labor supplied exceeds the quantity of labor demanded. It particularly affects low-skilled and young workers, who may find it harder to get jobs. Minimum wage laws prevent wages from falling below a legal floor. Minimum wages are one form of institutional wage rigidity—they prevent wages from adjusting downward in response to market forces. This can result in involuntary unemployment, where workers are willing to work at lower wages but cannot find jobs because wages are legally constrained.

Wage rigidity refers to the observation that wages often cannot be adjusted downwards as easily as they can be adjusted upwards.

Economists propose several reasons for wage rigidity. While factors like labor contracts and worker morale also play a role, one of the most direct examples is the minimum wage.

For instance, imagine a hypothetical market where the equilibrium wage is W_* and L_* workers are employed at this wage. At equilibrium, the number of workers seeking jobs equals the number of jobs offered by employers, and the sustainable output in this market is maximized.

Suppose the government imposes a minimum wage of W_m, which is higher than the market-clearing wage.

At this wage, many more workers are attracted to the market, but employers offer fewer jobs.

Employers cannot offer wages lower than the minimum wage, and they cannot be forced to hire more workers than they want to at the minimum wage.

This analysis shows how minimum wage laws can cause greater unemployment, with fewer workers employed in the market. This also means the market produces lower output due to a smaller number of workers.
