Interrelated Demand Rational Expectations Models for Two Types of Labour.

In this paper, the authors derive and estimate optimal dynamic interrelated labor demand curves for Dutch manufacturing blue and white collar labor. The driving forces of the labor demand model are the predetermined capital stock and the real wage costs of the two types of labor. Interrelation between the demand for two types of labor results only from the presence of serial correlation between the exogenous shocks of the forcing variables. It is found to be optimal for the firm to raise the number of white collar workers employed when increasing its blue collar work force. On the other hand, a single upswing in white collar employment has a displacement effect on the blue collar workers. Copyright 1990 by Blackwell Publishing Ltd
