M. Johannesson et Po. Johansson, SAVING LIVES IN THE PRESENT VERSUS SAVING LIVES IN THE FUTURE - IS THERE A FRAMING EFFECT, Journal of risk and uncertainty, 15(2), 1997, pp. 167-176
To estimate the discount rate for lives saved in the future a number o
f studies have been carried out on the trade-off between saving lives
now and in the future. A telephone survey is administered to about 1,7
00 individuals to test if the framing of the question affects the esti
mated trade-off. In one sample the question is framed as saving 100 li
ves today versus saving x future lives and in one sample the question
is framed as saving 100 future lives versus saving y lives today. The
result shows that the framing has a major impact on the trade-off.
