Differences in risk preference
- In the previous section, it was assumed that everyone maximized expected value.
- However, people often pay to avoid risk, whether by purchasing insurance or by sacrificing some potential "upside" for a bit more security, and there are substantial individual differences in the tendency to tolerate risk.
- Such differences can be exploited to create joint gains.
- Example
: Two business partners, Hank and Ida, own equal shares in a venture that has a 50% chance of becoming a bonanza. If the venture goes bonanza, Hank and Ida will be rewarded with $1,000,000 in profits. If the venture fails to go bonanza, the venture will just break even, producing no profit.
- There are not differences in opinion to exploit, only differences in willingness to tolerate risk.
- Hank is extremely risk averse, cautious in his personal and business finances.
- Ida, on the other hand, is glad to make decisions, even large stakes ones, on the basis of expected value.
- Case 1(each getting half of the proceeds)
: Hank and Ida each get half of the proceeds, in all cases. In other words, Hank and Ida will each receive $500,000 if the venture goes bonanza, and nothing otherwise.
