Demand for national telephone traffic in Spain from 1985-1989: an econometric study using provincial panel data

Article Abstract:

National telephone traffic demand equations for Spain are estimated using panel data techniques within a framework that considers the specific characteristics of the service. A generalized method of moments is used in the estimation, based on data from annual observations in Spain's 50 provinces. Results indicate that national telephone traffic is significantly sensitive to price, with an income elasticity under one and less sensitive to the number of telephone lines, with an income elasticity greater than one. The effect of tariff rebalancing on social welfare is estimated.
