RISK AVERSION AND DEMAND FOR INSURANCE BY INDIVIDUALS Why do individuals take actions to reduce risk? In this paper we analyze insurance demand when the utility function depends both upon final wealth and the level of losses or gains relative to a reference point. Insurance companies are aware of this behavior of risk-averse individuals. It is clear from above why people buy insurance for fire, accident, ill health and even life. We then show how this measure ariesv with compound-risk aversion, risk aversion and basis risk. In addition, as basis risk increases, demand for index insurance declines.

This loss occurs with probability π. The latter suggests a potential behavioural (or cultural) mechanism to isolate the influence of risk attitudes on the demand for PHI in publicly financed health systems. That the consumer's expected utility function yields a downward sloping demand curve for net insurance, i.e., the insurance pay-out less the premium due in the state in which the loss occurs, has been shown by Smith [14] and Ehrlich and Becker [5]. Given that there is probability of 0 5 for each outcome, expected utility of the two outcomes is given by. Therefore, the risk premium is the amount of money that a risk-averse individual will be willing to pay to avoid the risk.

Empirical research on risk aversion may be categorized into two main areas: (1) the measurement and magnitude of risk aversion, and (2) the empirical analysis of socio-demographic variables associated with risk aversion. In the case with marked-up premia and CRRA utility, we show that optimal insurance is linear in risk sharing and derive simple, analytical expressions for their slopes. cations. Consistent with our hypothesis of volatility-driven increases in risk-aversion, we nd that a one standard deviation increase in daily price volatility leads to a 3-6% increase in insurance policy sales. But it will be seen from the individual s utility function OU, that utility of 60 is equal to that of an assured and certain income of Rs.
