TESTING DYNAMIC MODELS OF THE FARM FIRM

In this paper two models of dynamic firm behavior are fitted to a data set developed from business records of Indiana dairy farms. The parametric restrictions implied by a cost-of-adjustment model are rejected. A less restrictive, disequilibrium model is accepted; this is a model of partial and interrelated adjustment among inputs and outputs. The results suggest that adjustment in quasi-fixed inputs is slow affecting the adjustment in variable inputs and outputs.
