Absolute v/s Relative Risk-aversion In simple terms, what we are measuring above is the actual dollar amount an individual will choose to hold in risky assets, given a certain wealth level w.

Risk aversion is a type of behavior that seeks to avoid risk or to minimize it. The risk premium is defined to be the difference between the expected payoff and the certainty equivalent.

In determining the risk aversion (A), we measure the marginal reward an investor needs in order to take on more risk.

Corollary 3.2 DM’s risk aversion against the multiplication y inhiswealthisdecreas- Fig. 8.2-1 describes the situation of an efficient frontier, which has been derived using the techniques shown in Section 8.1 from four assets, together with three separate indifference curves associated, respectively, to a lower risk tolerance (T = 10), average-high risk tolerance (T = 40), and a high-risk tolerance (low risk aversion) with T = 100. One such equation is the following utility formula: Utility Score = Expected Return - 0.5 x σ 2 A where A is the risk aversion coefficient (a number proportionate to the amount of risk aversion of the investor). It is positive for a risk-averse investor, zero for a risk-neutral investor, and negative for a risk seeker.
