Downside risk aversion (downside RA) and decreasing absolute risk aversion (DARA) are different concepts that describe preferences for which the harm from bearing risk is lessened by an increase in wealth. This note presents some intuitive explanations of the difference between the two concepts using...

This paper defines conditions for 'Increasing Risk' when the utility functions of risk averse investors are characterized by decreasing absolute risk aversion (DARA). Rothschild and Stiglitz (Journal of Economic Theory 1970, 2, 225–243, and 1971, 3, 66–84) define cases when a random variable...
The Arrow-Pratt measure of absolute risk aversion and a closely related measure of relative risk aversion also play crucial roles in the investigation of changes, induced by wealth increases, in the risk-taking behaviour of a single expected utility maximizing individual. This study has resulted in...
decreasing absolute risk aversionprudenceDownside risk increases have previously been characterized as changes preferred by all decision makers u(x) with u′′′(x) > 0. For risk averse decision makers, u′′′(x) > 0 also defines prudence. This paper finds that downside risk increases can ...

Proper risk aversionConvex absolute risk aversionBackground riskProper risk aversion, a pivotal concept in the study of behavioral conditions on utility functions, states that an undesirable risk can never be made desirable by the presence of an independent risk. It is well known that standard risk...
