Kahneman and Tversky Studied How People Manage Risk and Uncertainty

Question

Examlex · Accepted Answer

The Answer is Prospect theory is characterized by the following:
Certainty: People have a strong preference for certainty and are willing to sacrifice income to achieve more certainty. For example, if option A is a guaranteed win of $1,000, and option B is an 80 percent chance of winning $1400 but a 20 percent chance of winning nothing, people tend to prefer option A.
Loss aversion: People tend to give losses more weight than gains: They're loss‐averse. So, if you gain $100 and lose $80, it may be considered a net loss in terms of satisfaction, even though you came out $20 ahead, because you tend to focus on how much you lost, not on how much you gained.
Relative positioning: People tend to be most interested in their relative gains and losses as opposed to their final income and wealth. If your relative position doesn't improve, you won't feel any better off, even if your income increases dramatically. In other words, if you get a 10 percent raise and your neighbor gets a 10 percent raise, you won't feel better off. But if you get a 10 percent raise and your neighbor doesn't get a raise at all, you'll feel rich.
Small probabilities: People tend to underreact to low‐probability events. For example, you might completely discount the probability of losing all your wealth if the probability is very small. This tendency can result in people making very risky choices.
