In this article, we estimate the price elasticities of demand for subscription and consumer switching costs for mobile telephony. We use a panel of Portuguese consumer level data to estimate a series of multinomial and mixed logit models. The demand for subscription is elastic. Switching costs...

This article assesses the unilateral effects on prices of a merger in the Portuguese mobile telephony market. We use aggregate quarterly data from 1999 to 2005 and a nested logit model to estimate the price elasticities of demand and the marginal costs of subscription of mobile telephony. Given...

This paper uses a unique individual transactions data set to investigate the effects of internet purchase on the prices paid for airline tickets. The analysis also investigates the effects of changes in the percentage of online transactions on both online and offline prices and on price...

We study how access pricing affects network competition when consumers' subscription demand is elastic and networks compete with non-linear prices and can use termination-based price discrimination. In the case of annexed per minute termination charge, our model generalizes the results of Gans...

Local telecommunications competition was an important goal of the 1996 Telecommunications Act. We evaluate the consumer welfare effects of entry into residential local telephone service in New York State using household-level data from September 1999 to March 2003. We address the prevalence of...
