Accumulation of Human Capital and the Business Cycle

Characteristics of business cycles are quite different across developed countries. Real wages and working hours are less sensitive to exogenous shocks in the United States than they are in Britain and Japan. Using a model with a microeconomic foundation, this paper provides an economic explanation of these differences. The cost of on-the-job training plays a crucial role. Workers seldom quit their jobs when the sunk training cost is high. In such economies variances in employment and output become small and shocks tend to be absorbed by working hours and real wages. Thus these characteristics do not necessarily indicate that the economy is more efficient.
