Efficiency vs. market-power effects in the mobile-voice industry [PDF]
This paper suggests a new procedure for separating the market-power effect from the efficiency effect when cost data are not available. We examine a panel of data on 177 mobile-voice operators in 45 countries from 1999:1 to 2004:2 and find that a 1 ...
