Opportunity Cost of Capital, Marginal Cost of Funds and Numeraires in Cost-Benefit Analysis

MPRA Paper from University Library of Munich, Germany

Abstract: The question of choice of social discount rate, which is related to the choice of numeraire in CBA, has been unsettled for decades. The solution lies in using both the social time preference rate (STPR) and the social opportunity cost rate (SOCR) simultaneously but in different roles. There are two proposed methods of using the two rates, however, one of which places a great emphasis on the marginal cost of funds (MCF). This paper explores the interaction between these concepts using a numerical example to show how the alternative discounting methods compare and how one of them works even if the SOCR differs from the rate of fall of the value of the possible numeraires.
