In economics and finance, exponential utility is a specific form of the utility function, used in some contexts because of its convenience when risk (sometimes referred to as uncertainty) is present, in which case expected utility is maximized. Formally, exponential utility is given by: is a variable that the economic decision-maker prefers more of, such as consumption, and is a constant that represents the degree of risk preference ( for risk aversion, for risk-neutrality, or for risk-seeking). In situations where only risk aversion is allowed, the formula is often simplified to .

dbo:abstract
  • En economía y finanzas, la utilidad exponencial se refiere a una forma específica de la función de utilidad, que se utiliza en algunos contextos, por su comodidad a la hora de riesgos (a veces referido como la incertidumbre) está presente, en cuyo caso la utilidad esperada se maximiza. Formalmente, la utilidad exponencial viene dada por: , donde c es una variable que toma las decisiones económicas tiene que ver con, por ejemplo, el consumo y la un es una constante positiva que representa el grado de aversión al riesgo . La variable C en sí será una función de opciones del agente (por ejemplo la oferta de trabajo , etc, dependiendo del enfoque del modelo) y de exógenos estocásticos variables. Tenga en cuenta que el término aditivo 1 en la función anterior es matemáticamente irrelevante y es (a veces) incluido solo para la característica estética que mantiene el rango de la función entre cero y uno sobre el dominio de los valores no negativos para c. La razón de su irrelevancia es que maximizar el valor esperado de la utilidad da el mismo resultado para la variable de elección como no maximizar el valor esperado de ; Ya que los valores esperados de utilidad (en contraposición a la función de utilidad en sí) se interpretan de forma ordinal en lugar de cardinal , el rango y el signo de los valores de utilidad esperados son de ninguna importancia. La función de utilidad exponencial es un caso especial de la aversión al riesgo absoluta hiperbólicas funciones de utilidad. (es)
  • In economics and finance, exponential utility is a specific form of the utility function, used in some contexts because of its convenience when risk (sometimes referred to as uncertainty) is present, in which case expected utility is maximized. Formally, exponential utility is given by: is a variable that the economic decision-maker prefers more of, such as consumption, and is a constant that represents the degree of risk preference ( for risk aversion, for risk-neutrality, or for risk-seeking). In situations where only risk aversion is allowed, the formula is often simplified to . Note that the additive term 1 in the above function is mathematically irrelevant and is (sometimes) included only for the aesthetic feature that it keeps the range of the function between zero and one over the domain of non-negative values for c. The reason for its irrelevance is that maximizing the expected value of utility gives the same result for the choice variable as does maximizing the expected value of ; since expected values of utility (as opposed to the utility function itself) are interpreted ordinally instead of cardinally, the range and sign of the expected utility values are of no significance. The exponential utility function is a special case of the hyperbolic absolute risk aversion utility functions. (en)
