A multiproduct cost model is estimated on a panel of US local exchange carriers from the period 1989-1999.

This paper provides some estimates of demand elasticity for prepaid cellular voice and short message service (SMS) in South Africa by fitting a structural discrete consumer choice model to a cross-sectional data set on Vodacom customers collected in 2005. We find higher price elasticities than...

We develop a model of competition in prices and infrastructure among mobile network operators. Consolidation can increase market power, but economies of scale, which we derive from physical principles, lead to more efficient data transmission. Estimating our model with French consumer and...

We analyze demand for prepaid cellular voice and short message service (SMS) in South Africa by means of a demand-and-supply structural model based on a multinomial specification fitted to a cross-sectional data set on Vodacom customers collected in 2005. We find that consumers are very...
