Firm size and productivity in Spain: a stochastic frontier analysis

This paper analyses the performance of the small and medium-sized manufacturing firms during the period 1995-2001, focusing on the degree of technical inefficiency and its determinants. We use a micro panel data set to simultaneously estimate a stochastic frontier production function and the inefficiency determinants using an unbalanced panel of manufacturing firms. Our empirical results suggest that small and medium-sized firms tend to be less inefficient than the large firms are. Also, we centre our analysis in the effect on efficiency of some organisational factors related to the managerial ability to use and adjust capital and labour properly.
