In this paper we evaluate the inefficiency generated by an inadequate structure of the fixed inputs and by the difficulty to adjust them in the short-run in a sample of Romanian firms in the chemical industry over the period 1996-1997. We use Data Envelopment Analysis (DEA) and apply this methodology in an innovative setting using a cost analysis instead of the technical efficiency approach. The results show inefficiency in most of the cases due to a low degree of capacity utilisation.
