The Structure of Production of the Spanish Telecommunications Sector

Empirical Economics, 1997, vol. 22, issue 3, 30 pages

Abstract: The purpose of this paper is to provide empirical measures of the returns to scale coefficients, substitution elasticities between capital and labor, their marginal productivities, and the profitability of inputs in the Spanish telecommunications industry. The results of this study indicate that constant returns to scale can strongly be rejected and that the profitability indices of both factors have risen consistently since 1974. Furthermore, it concludes that the company is relatively overcapitalized, a result generally consistent with the Averch-Johnson effect for rate of return regulated monopolies.
