Dynamic factor demands and market structure under rational expectations: some estimates for the Italian manufacturing system

This paper deals with a dynamic model of the behaviour of firms under rational expectations. The adjustment cost framework is followed to describe production technologies. The objective of firms is to maximize the stream of future profits under rational expectation. First-order conditions for the optimum are derived with respect to input demands and one output supply. The output market structure is modelled in order to test price taking behaviour. The adjustment costs of quasi-fixed inputs are internal and interrelated. The model is estimated for the Italian manufacturing system with encouraging results.
