Resolving the Discounting Dilemma

Szabolcs Szekeres

MPRA Paper from University Library of Munich, Germany

Abstract: Social Time Preference (STP) and Social Opportunity Cost (SOC) discounting differ in their objectives, but STP discounting measures capital costs incorrectly. The two-rate discounting method proposed here corrects this error, which current methods of shadow pricing capital (SPC) don’t. Thereafter project choice discrepancies between alternative methods decrease substantially and the choice between them becomes unambiguous. The SOC rate is the hurdle feasibility rate either way. The marginal cost of public funds (MCF) correction is not an alternative to SPC correction; both must be used in conjunction when warranted. The Ramsey equation is a tautology that cannot predict the STP rate.
