Recent changes in the internal structure of wages and employment in large and medium Japanese firms can be characterized in a parsimonious way with two stylized facts. First, internal wage differentials are countercyclical but without a trend. Second, spans of control trend downward but are acyclical. The paper tries to explain these changes using a simple efficiency wage model that combines exogenous supply and demand shocks with the endogenous determination of relative wages and spans of control by cost-minimizing firms that operate in an environment characterized by asymmetric information and job security.
