Abstract: In this paper we use a theoretical model for the demand of telecommunication services to derive econometric models of the business demand for telephone traffic in Spain for the period 1980-1991. Using quaterly data, we estimate separate equations for the different types of toll traffic: local, long distance, national and international. We use cointegration techniques to obtain long run and short run equations, both estimated separately in two steps and jointly, in one step. A battery of diagnostics is applied to each of the equations, Price and output elasticies agree with previous findings and could be used for analizing the revenue effects of changes in tariffs and medium term forecasting of traffic and revenues.
