Utility and Marginal Utility

Risk Aversion :

\sigma = {{ (1/(params.rra)) | extendedReal:2 }}

u(c) = \frac{c^{1 - 1/\color{ {{color('growth')}} }{\sigma}} - 1}{1 - 1/\color{ {{color('growth')}} }{\sigma}} || = {{ model.utilityFormula()}}

u(c_A) = {{ model.utilityFormula(params.c)}} || = {{ model.utilityAtQuantity(params.c) | number: 2}}
