  The theoretical literature on mobile termination rates (MTRs) is inconclusive on how the level of MTRs affects overall consumer charges and firms' profits. We show that when firms offer bundles with fixed included usage – a tariff structure that has become more common in recent years – an identical change in all MTRs does not affect firms' retail prices or profits. We use a panel dataset from saturated European markets to estimate the effect of MTRs on mobile operators' profits. As predicted by the theoretical model, we cannot reject the fact that firms' profits are unaffected by an identical change in all MTRs.

  Text messaging has become an important revenue component for most mobile operators. We develop a simple model of demand for mobile services incorporating dynamics of information exchange. We show that when incoming communication stimulate outgoing communication, services that initially may be perceived as substitutes, such as mobile text and voice, may evolve into complements in terms of the price effect when the network size becomes large. We estimate the demand for text messaging in the Norwegian market and find that the cross-price effect of voice depends on the network size. Voice is a substitute for text messages for small network sizes, and a complement for large network sizes.

  We consider two different qualities of broadband access, one that simply means greater access speed to Internet applications and content, and a premium version that also gives access to interactive TV services. Based on a market survey we find that potential consumers of this premium broadband access do not consider basic broadband Internet access as a substitute. The price of basic broadband does not constrain the price that may be charged for the premium broadband that allows for interactive TV services.

  The comprehensive theoretical literature on mobile termination rates (MTRs) is inconclusive on how the level of MTRs affects overall consumer charges and firms’ profit. In a theoretical model, well suited for econometric implementation, we show that where consumers buy a bundle with included usage, as we now observe in the market, the level of MTRs has no impact on retail prices and firms’ profit. We use a panel data set from saturated European markets and find that an identical change in MTRs does not have a significant impact on firms’ profit.

  Text messaging has become an important revenue component for European and Asian mobile operators. We develop a simple model of demand for mobile services incorporating the existence of call externalities and network effects. We show that when incoming messages and calls stimulate outgoing communications, services that are perceived as substitutes, such as mobile text and voice, may evolve into complements in terms of the price effect when the network size becomes large. We estimate the demand for text messaging in the Norwegian market and find that the cross-price effect of voice depends on the network size. Voice is a substitute for text messages for small network sizes, and a complement for large network sizes.
