Suppose that the United States is preparing for the outbreak of an Asian viral disease, which, if a vaccine is not developed, is expected to kill 600 people. Two alternative vaccination programs have been proposed. The benefits of the two vaccination programs are described as follows:
Program A: 200 lives are saved
Program B: 1/3 probability that 600 lives are saved
Tversky and Kahnman (1981, 1986) find that most people prefer Program A.
Now consider the following descriptions: Program A: 400 die
Program B: 2/3 probability that 600 die
Tversky and Kahnman find that most people prefer Program B.
Since the first set of descriptions is identical to the second, choices seem to be inconsistent.
A. How does this example related to the framing problem discussed by Kahneman and Tversky?
B. How do the descriptions presented here pertain to risk-aversion and risk-seeking preferences?
