The efficiency wage model is a concept in labor economics that explains why firms may pay wages above the market-clearing level. The core idea is that higher wages can increase worker productivity, reduce turnover, attract better talent, and discourage shirking. Unlike the classical competitive labor market model, where wages adjust to equate supply and demand, the efficiency wage hypothesis suggests that firms have an incentive to pay more than the equilibrium wage to enhance efficiency and overall profitability. One key result of the efficiency wage model is that involuntary unemployment can coexist with labor demand. Since firms pay above-market wages, the total number of workers employed at this higher wage is less than the number who would work at a lower wage, generating a surplus of labor. This provides an explanation for persistent unemployment even in competitive markets. Another result is the reduction of shirking behavior. Workers have a strong incentive
