A methodology for determining public investment criteria

Abstract Cost-benefit analysis is a popular method of evaluating both public and private investments. This paper explores the theoretical basis of cost-benefit analysis, the methodology of its application and the policy ramifications arising from its application in terms of public investments. The discussion presented in this paper is relevant to public investments undertaken at all levels of government. A main conclusion of this paper is that the social conscience of the planner or decision-maker and his knowledge of the benefits and shortcomings of cost-benefit analysis are key factors in successfully implementing public investments.
