Do States Tax Wireless Services Inefficiently? Evidence on the Price Elasticity of Demand

The relationship between mobile and fixed-line communications: A survey

“…Empirical work on mobile demand containing fixed-line call prices seems to be restricted to studies for the US by Ingraham and Sidak (2004) and Rodini (2009). They both use the same 1999-2001 bill-harvesting data as Rodini et al (2003) for a large number of households.…”

“…found by Ingraham and Sidak (2004). Their price variable is the customerspecific total wireless bill amount per subscriber divided by total wireless minutes.…”

Universal telecommunication service: A world perspective

“…Ward and Woroch (2004) find a stronger substitution effect with the same data using the Linear Approximate/Almost Ideal Demand System. Work by Ingraham and Sidak (2004) suggests strong substitution between mobile service and wireline long distance service. 2 International telecommunications modeling that includes mobile service has also been undertaken.…”

License prices for financially constrained firms

“…21 However, early adopters of cellular telephony probably had relatively inelastic demand, so that demand at lower prices is likely substantially more elastic than these estimates suggest. For instance, using data from 1999 to 2001, Ingraham and Sidak (2004) estimate wireless services price elasticity in the range 1.12 and 1.29. In addition, the demand for 3G services such as video and gaming is likely more elastic than wireless telephony, because the luxury component is larger.…”
