However, it is desirable to saving and consumption patterns. However, it uses the number of lives saved by the present-ori-ented program. For example, in the Mary-land poll nearly 40 percent of the respon-dents preferred the program saving 100 lives today to one that would save 4,000 lives 25 years from now. Similarly, 47 percent of those surveyed preferred to save 100 lives today to 7,000 lives 100 years in the future.

The traditional model of time preferences employed by economists is characterised by constant timing aversion. The available evidence suggests that this is not an appropriate assumption. This paper examines evidence for constant and decreasing timing aversion with respect to saving lives. are lowering their rates, and most OECD countries now apply rates in the 3 to 5.5 percent range.
