Published in volume 15, issue 1, pages 219-232 of Journal of Economic Perspectives, Winter 2001, Abstract: Economists ubiquitously employ a simple and elegant explanation for risk aversion: It derives from the concavity of the utility- Risk aversion is a preference for a sure outcome over a gamble with higher or equal expected value. Conversely, the rejection of a sure thing in favor of a gamble of lower or equal expected value is known as risk-seeking behavior.. The psychophysics of chance induce overweighting of sure things and of improbable events, relative to events of moderate probability. important. Risk aversion impinges on the equilibrium through the portfolio allocation process and thus through the equilibrium risk that the economy is willing to sustain. It also determines the discounting for risk, in deriving the certainly equivalent level of income that corresponds to … Risk with unknown probability distribution of the outcomes. From Wikipedia: "Risk aversion comes from a situation where a probability can be assigned to each possible outcome of a situation and it is defined by the preference between a risky alternative risk risk-aversion.

Economists have developed models of risk aversion using the concept of utility, which is a person’s subjective measure of well-being or satisfactions, Every level of wealth provides a certain amount of utility, as shown by the utility function In Figure I.
ADVERTISEMENTS: Most people are risk averters and therefore they buy insurance to avoid risk. Now an important question is how much money or premium a risk-averse individual will pay to the insurance company to avoid risk and uncertainty facing him. Suppose the individual buys a house which yields him income of Rs. 30 thousands per […]
The extent of an individual’s risk aversion can be shown by using indifference curves that relate expected income (measured by the mean along the vertical axis) to the variability of expected income (measured by the standard deviation along the horizontal axis). The prospect theory starts with the concept of loss aversion, an asymmetric form of risk aversion, from the observation that people react differently between potential losses and potential gains.

Risk Aversion This chapter looks at a basic concept behind modeling individual preferences in the face of risk. As with any social science, we of course are fallible and susceptible to second-guessing in our theories.

If investors are risk averse, higher-risk investments must offer higher expected yields. Risk aversion is a term often associated with economics and finance.

The measure ρ (x) = − v ″ (x) v ′ (x) is known as the Arrow-Pratt measure of risk aversion, and also as the measure of Formally, the degree of risk aversion depends on the concavity of the graph of utility of wealth: the greater the concavity, the greater the degree of risk aversion (because the greater the rate at which utility losses grow with losses of wealth).
