economics, the isoelastic function for utility, also known as the isoelastic utility function, or power utility function, is used to express utility in terms...

alternative utility functions such as: CES (constant elasticity of substitution). Isoelastic utility Exponential utility Quasilinear utility Homothetic...

competition. Note the difference between CES utility and isoelastic utility: the CES utility function is an ordinal utility function that represents preferences...

utility function, the exponential utility function, and the isoelastic utility function. A utility function is said to exhibit hyperbolic absolute risk aversion...

This feature explains why the exponential utility function is considered unrealistic. Though isoelastic utility, exhibiting constant relative risk aversion...

Neumann–Morgenstern expected utility index. Importantly, unlike von Neumann–Morgenstern utility functions (e.g. isoelastic utility), Epstein–Zin preferences...

disentangled from the coefficient of relative risk aversion. The isoelastic utility function u ( c ) = c 1 − ρ − 1 1 − ρ {\displaystyle u(c)={\frac {c^{1-\rho...

In mathematical economics, an isoelastic function, sometimes constant elasticity function, is a function that exhibits a constant elasticity, i.e. has...

constant-relative-risk-aversion form for within period utility (also called the power utility or isoelastic utility). The reason is that, in combination with additivity...

^{t}u(c_{t}^{vol})} and solving for λ {\displaystyle \lambda } For the case of isoelastic utility, given by u ( c t ) = c t 1 − θ − 1 1 − θ {\displaystyle u(c_{t})={\frac...
