The practice of setting marginal prices below marginal costs is so common in telecommunications offerings that it can justifiably be labeled a stylized fact. In this paper, we present a stylized model that establishes conditions under which this practice is economically efficient and...

The authors study optimal nonuniform pricing in a setting where a customer's demand at the start of a billing period contains a random variable whose realization becomes known by the end of the billing period. In this context, an optional calling plan is a tariff which the consumer must select...

We analyze optimal multiproduct nonlinear prices in the case where consumer tastes are characterized by more than one taste parameter. We present conditions under which the optimal nonlinear price schedule can be computed by finding optimal price schedules separately for each market. If so, they...

Traditional economic analyses of the peak-load problem typically assume an unrealistic degree of regularity in demand during well-defined peak and off-peak periods. This issue is addressed through a comprehensive statistical model that separates demand into its systematic and stochastic...
