Utilidade de Bernoulli

up:: 062c MOC Loterias

“It is important to distinguish between the utility function $U(\cdot )$, defined on lotteries, and the utility function $u(\cdot )$ defined on sure amounts of money. For this reason, we call (…) $u(\cdot )$ the Bernoulli utility function.” (MAS-COLELL et al., p. 184)

A concavidade dessa utilidade diz respeito a quão avesso ao risco um agente racional é.
