Nonmonotone monetary utility (source code)

= Nonmonotone monetary utility

A <utility function> on monetary amounts need not be increasing merely because preferences obey the <expected utility hypothesis>. The outcome labels do not themselves supply a preference order. For example, values $u(1)=2$, $u(2)=0$, $u(4)=3$ define consistent <expected utility> comparisons even though the amount $2$ is least preferred. Preferring more money is an additional assumption. It is distinct from <risk aversion>, which concerns the effect of spreading uncertainty for a specified increasing <utility function>.
