This paper describes an incentive mechanism that is shown to enforce the use of Ramsey prices by multiproduct monopolies. The constraint given is simple. It limits information requirements on the regulatory agency to bookkeeping data of the firm. Its implementation could be easily controlled by...

In this note, an alternative method is developed for determining the range of values assumed by the Lagrange multiplier of Averch and Johnson's constrained maximization problem. By assuming that the regulated firm's profit function is single-peaked, the approach is rather general.
