| Abstract: | This paper provides 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 indicate that constant returns to scale can strongly be rejected and that the profitability indices of both factors have risen consistently since 1974. The paper concludes that the company is relatively overcapitalized, which result is generally consistent with the Averch-Johnson effect for rate of return regulated monopolies. |
