An innovation in this paper is to introduce a time‐to‐build technology for the production of market capital into a model with home production. Our main finding is that the two anomalies that have plagued all household production models—the positive correlation between business and household investment, and household investment's leading business investment over the business cycle—are resolved when time to build is added.

Wage and unemployment responses to changes in economic environment are compared for efficiency wage and frictional models. Changes in aggregate demand, persistence of job-specific shocks, cost of living, and unemployment benefits are considered. Wages and unemployment move in the same direction in the two models, except that an upward shift in aggregate labor demand can reduce the real wage in the efficiency wage, but not the frictional, model. In a numerical simulation calibrated to U.S. data, real productivity shocks in the efficiency wage model yield a ratio of unemployment to wage variability close to that of the United States.
