Use calculus to determine whether the following utility functions imply risk aversion, risk neutrality or risk preference: a. U(W)equalsln(W) b. U(W)equalsUpper W Superscript 0.6 c. U(W)equalsUpper W Superscript 2.7 d. U(W)equals4W. The utility function, U(W)equalsln(W), implies ▼ risk aversion risk preferring risk neutrality because (as a function of W) StartFraction partial derivative squared Upper U (Upper W )Over partial derivative Upper W partial derivative Upper W EndFraction equals nothing. (Properly format your expression using the tools in the palette. Hover over tools to see keyboard shortcuts. E. g., a superscript can be created with the ^ character.)
