Abstract
This paper investigates further the connection between the concept of risk-aversion and the property of concavity of the utility function of the agent. Improved specifications of the Jensen inequality are used for stating a number of local properties of certainty equivalents under milder regularity assumptions on the utility function than those made in literature. The paper concludes by illustrating a few applications of this theory.File in questo prodotto:
