The value of life extension and the marginal rate of time preference: a pilot study

Abstract
The aim of this paper is to introduce and test a new approach for the measurement of the marginal rate of time preference for life-years gained based on contingent valuation techniques. A simple binary willingness to pay question is administered in a general public sample of two age groups (34–5 years and 64–5 years). In this pilot study, the estimated marginal rate of time preference is 1.3%.
