Attitudes to risk and expected value
Figure 6.6 shows the general shapes of the utility curves of (a) a risk-averse investor,
(b) a risk-lovinginvestor and (c) a risk-neutralinvestor. A risk-neutral investor views
equally entering a wager whose expected value is zero, and doing nothing.

utility of wealth
against wealth for
three individuals
with different
attitudes towards
risk
The risk-averse individual (graph a) would gain less satisfaction from having an additional
£1 than the satisfaction that would be lost from having £1 less. The risk-loving individual
(graph b) would gain more satisfaction from having an additional £1 than would be lost from
having £1 less. To the risk-neutral individual (graph c), the gain in satisfaction from having
an additional £1 is equal to the loss in satisfaction of having £1 less.
