The aim of this paper is to analyse the factors explaining the technical efficiency of Spanish industrial sectors during the period 1991–1994 using the Survey of Business Strategies (SBE) of the Ministry of Industry and Energy. It analyses whether efficiency can be explained by factors external to the firm such as the degree of competition in the markets in which it operates, characteristics of the firm (size, organization, advantages of location, participation of public capital, etc.), as well as the effects of dynamic disturbances that may affect the degree of utilization of the productive capacity.

This paper analyses the importance of different technological inputs (R&D and human capital) and different spillovers in explaining the differences in patenting among Spanish

The aim of this paper is to analyse the (in)efficiency of the Spanish regions over the period 1986-91, using a stochastic frontier approach. Different distributional assumptions are used to estimate each region's (in)efficiency as well as the influence of the inputs on the productivity gains: half-normal, truncated-normal and exponential models. The results show that, on average, the inefficiency varies between the 15% and 19%.
