We study the properties of simple mobile broadband Internet plans characterized by a data cap and an up-front price. Assuming demand uncertainty and a positive correlation between users’ valuations and (expected) demands, we show that a monopolistic provider does always find it convenient to offer one plan with binding cap together with an unlimited one. We characterize all the elements of the profit-maximizing plans, showing that medium users, but not heavy users, will incur the risk of being capped, and that, relative to the benchmark case of unlimited access only, the introduction of a plan with cap leads to a redistribution of surplus from high users to low users. The overall effect on social welfare and users’ surplus is, in general, ambiguous, but is certainly negative if low valuation users have a sufficiently homogeneous demand for Internet traffic.

Abstract
We study the properties of simple mobile broadband Internet plans characterized by a data cap and an up-front price. Assuming demand uncertainty and a positive correlation between users’ valuations and (expected) demands, we show that a monopolistic provider does always find it convenient to offer one plan with binding cap together with an unlimited one. We characterize all the elements of the profit-maximizing plans, showing that medium users, but not heavy users, will incur the risk of being capped, and that, relative to the benchmark case of unlimited access only, the introduction of a plan with cap leads to a redistribution of surplus from high users to low users. The overall effect on social welfare and users’ surplus is, in general, ambiguous, but is certainly negative if low valuation users have a sufficiently homogeneous demand for Internet traffic.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
