From monetary policies to the climate change problem, from the burden of private credit card debts to the evaluation of public projects, discount rate is the central issue, yet there is little clear understanding about the nature of discounting. In this paper, applying a newly developed production theory, we discuss how discount rate is related to other factors in social systems, such as risk, ...

Nearly all discussions about the appropriate consumption discount rate for climate-change policy evaluation assume that a single discount rate concept applies. We argue that two distinct concepts and associated rates apply. We distinguish a social-welfare-equivalent discount rate (rSW) appropriate for determining whether a given policy would augment social welfare (according to a postulated soc...

BACKGROUND The present study aimed to provide better insight on methodological issues related to time preference studies, and to estimate private and social discount rates, using a rigorous systematic review and meta-analysis. METHODS We searched PubMed, EMBASE and Proquest databases in June 2013. All studies had estimated private and social time preference rates for health outcomes through s...

Social discounting in economics involves applying a diminishing weight to community-wide benefits or costs into the future. It impacts on public policy decisions involving future positive or negative effects, but there is no consensus on the correct basis for determining the social discount rate. This study presents an evolutionary biological framework for social discounting. How an organism sh...

this paper presents a theoretical model in order to determine tile expected rate of durable good`s supply over time. the social plaliner maximizes tile sum of the discount ed net benefit. subject to the stochastic fluctuation in the stock of durable goods. it turns out that a social planner increases the expected rate of supply since uncertainty increases the user's loss from the view poin...
