Abstract

This paper presents an econometric analysis of factor demands in the Norwegian primary aluminium industry using annual plant-level panel data. The translog cost function approach is applied, and a multivariate error-correction model of the cost shares of labour, raw materials and electricity is estimated. Capital is assumed tobe quasi-fixed. The hypothesis of fixed input coefficients is rejected for this industry, but the estimated own-price and cross-price elasticities suggest that relative price variations have limited effect on conditional factor demands.
