The aim of this paper is to analyse the technical efficiency of the productive sectors of the Spanish regions over the period 1980-91. We estimate a production function using an stochastic frontier approach for the productive sectors under three different distributional assumptions for the...

The aim of this paper is to analyze the origin of the geographical distribution of the technological innovation analyzing, at the sometime the effect of such activity on indicators of productivity. For this reason, it is taken as unit of analysis the set of the Spanish autonomous communities in...

The aim of this paper is to find out the determinant factors of innovation. In order to do so, microeconomic data from a sample of 2000 Valencian firms in the year 1992 is used. Starting from Schumpeter's hypothesis on the role of firm's size in the innovation process, it is shown that small...

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:...
