Item Analiza kosztów i korzyści w ocenie przedsięwzięć inwestycyjnych(Wydział Prawa i Administracji UAM, 1984) Janc, AlfredPresentation of essentials of the cost-benefit analysis system is the task of the article als well as indicating at potentials of that system for theoretical propositions and practical conclusions recently drawn and aimed at means of functioning of Polish economy. The author characterises sources of the cost-benefit analysis concept, solutions adopted in that system, assessments of investments projects, and relations of the CBA with such branches of knowledge as political economy, econometrics and planning. The author focuses on problems of shadow prices upon indicating at differences characterizing the modern social cost-benefit analysis as compared to traditional financial measures of private payability. To simplify the matter, calculation of shadow prices is one of the stages in the three stage process of estimating social payability of investment ventures. The other stages define a target function to be maximized and formulate a decisional criterion which is to facilitate inputs of perceived social costs and benefits to a form which enables comparing the investment project with other alternatives, and in consequence, its acceptance or rejection. It is stated by the author that in spite of the last two decades of animated discussions, of numerous improvements in theoretical formula and practical applications, there is no entire consent to the CBA procedures which could be named universal and serve as guidelines in all situations. It is also painted out that various elements present in the cost-benefit analysis and referring to theoretical grounds of that system have already been utilized in practice eg. of the Polish planning or investment effectiveness calculus. That particular fitness of the cost-benefit analysis for the centrally planned economies has been often emphasised by authors studying the CBA.
