ABSTRACTAlthough price caps have desirable efficiency properties, it is well known that they may create incentives for a regulated firm to attempt to lower its costs via reductions in service quality. Thus, the regulators often employ quality standards or other methods designed to have allowed prices reflect delivered service quality levels. In this paper, we present a system of quality‐corrected price caps that results in efficient pricing and quality provision.

ABSTRACTThis paper considers the issues of existence and uniqueness of average cost pricing equilibria within the context of a single, regulated, multiproduct monopoly with additively separable costs. We employ basic degree theoretic arguments to establish conditions under which an average cost pricing equilibrium exists. The degree theoretic approach permits the development of uniqueness results in a very natural manner.
