A discounting framework for regulatory impact analysis

This article presents a methodology designed to facilitate the systematic comparison of alternative discounting procedures for the costs and benefits of industrial regulatory activity. A discounting framework developed by Bradford is adapted for use in the context of industry regulation. Within this framework, the choice among the various discounting procedures is reduced to a choice between assumptions about various economic and financial parameter values. As an illustration of the way in which the framework can be applied, the article includes an examination of the validity of parameter assumptions implied by the discounting approach currently used by regulatory agencies in their analyses of regulations affecting the motor vehicle industry. Several hypothetical programs are analyzed to demonstrate the broad differences in program treatment that might be expected if this current discounting approach were replaced by procedures generated within the framework from more reasonable parameter assumptions. Sensitivity of the benefit/cost calculations to uncertainty about underlying parameters is also briefly discussed.
