The conditions of spectrum allocation or reallocation are significant in determining the market structure in the telecom sector which in turn affects the prices and the quality of mobile networks. In a more concentrated market, the quantity of spectrum is less diluted, and operators can offer...

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...

Conditions under which spectrum is allocated are significant in determining the market structure in the telecom sector which in turn affects the prices and the quality of mobile services. In a more concentrated market, the quantity of spectrum is less diluted, and operators can offer higher...

We present a structural model to investigate the effects of horizontal cooperation on investment in the context of telecommunication networks. More specifically, we estimate the effect of network sharing in the mobile telecommunications industry on prices, network quality and consumer welfare....

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...
