Access regulation under asymmetric information about demand

Author

  • Joao Vareda

Abstract

We study the impact of access regulation in a telecommunications market on an entrant's decision whether to invest in a network or ask for access when the regulator cannot observe its potential demand. Since the entrant has incentives to not compete vigorously right after entry in order to convince the regulator that it needs cheap access in the future, the regulator must set access prices which tend to be distorted (lower or higher) as compared to ?rst best. Still, this is better than committing to ignore ex post demand information. Consulting the entrant earlier about its expectations improves welfare and may help to achieve the first best.
