Wage Determination

The text offers considers wage determination from two perspectives: bargaining and efficiency wages. Wage bargaining between employers and employees takes many different forms. In some occupations, wages are determined by collective bargaining between unions and firms. In the United States, less than 15% of workers are covered by collective bargaining agreements. Highly or uniquely skilled workers (e.g., athletes, entertainers) engage in individual bargaining with their employers. For jobs that require little skill, employers may make take-it-or-leave-it wage offers.

Efficiency wage theories are motivated by the idea that labor productivity is related to the wage. Paying a high wage may improve employee morale. Alternatively, a high wage may reduce turnover, which can be advantageous to the firm if it takes time to train new workers. From this perspective, firms have an incentive to offer a wage above the reservation wage—the wage at which a worker is indifferent between working or becoming unemployed.

The text summarizes the complex wage determination process by focusing on two factors. First, wage outcomes depend on labor market conditions, which can be proxied by the unemployment rate (u). When the unemployment rate is high, it is relatively easier for firms to replace workers and harder for workers to find new jobs, so worker bargaining power is relatively low. In addition, workers will be highly motivated to work and will be unlikely to quit, so firms have less incentive to pay a wage above the reservation wage. Second, given the unemployment rate, there are institutional and structural factors (summarized by the variable z) that affect the bargaining power of workers relative to employers. These factors include, among other things, the generosity of unemployment insurance and the level of the minimum wage.

These points suggest an aggregate wage determination equation of the following form:

W=P^eF(u, z). (6.1)

The nominal wage depends on the price level, because both workers and firms care about the real wage. However, wages are changed infrequently, so the price level that matters is the one that prevails over the duration of the contract. Since this future price level is unknown, wage determination depends on the expected price level.
