The choice of an overall discount rate for climate change investments depends critically on how di¤erent components of investment payo¤s are discounted at di¤ering rates reecting their underlying risk characteristics. Such underlying rates can vary enormously, from 1% for idiosyncratic diversi able risk to 7% for systemic nondiversi able risk. Which risk-adjusted rate is chosen can have a huge...
We study the spread of social norms for time preferences, and the effect of the transmission process on equilibrium consumption and interest rates. In the model, consumption is more salient than non-consumption. Owing to visibility bias and the availability heuristic, people infer that low saving is normative and increase their own discount rates accordingly. This effect is self-reinforcing at ...
We estimate discount rates of 555 subjects using a laboratory task and find that these individual discount rates predict inter-individual variation in field behaviors (e.g., exercise, BMI, smoking). The correlation between the discount rate and each field behavior is small: none exceeds 0.28 and many are near 0. However, the discount rate has at least as much predictive power as any variable in...
In general terms, decreasing impatience means decreasing discount rates. This property has been usually referred to as hyperbolic discounting, although there are other discount functions which also exhibit decreasing discount rates. This paper focuses on the measurement of the impatience associated with a discount function with the aim of establishing a methodology to compare this characteristi...
The last few years have witnessed important advances in our understanding of time preference and social discounting. In particular, several rationales for the use of time-varying social discount rates have emerged. These rationales range from the ad hoc to the formal, with some founded solely in economic theory while others reflect principles of intergenerational equity. While these advances ar...
OBJECTIVES Discounting of costs in health-related economic evaluation is generally regarded as uncontroversial, but there is disagreement about discounting health benefits. We sought to explore the current recommendations and practice in health economic evaluations with regard to discounting of costs and benefits. METHODS Recommendations for best practice on discounting for health effects as ...
