Consider the lottery that assigns a probability r of obtaining a level of consumption CH and a probability 1– an individual facing such a lottery with utility function u(c) that has the properties that more is better (that is, a strictly positive marginal utility of consumption at all levels of c) and diminishing marginal utility of consumption, u"(c) < 0. As usual, we are using the shorthand u'(c) = consumption and u"(c) = -T of obtaining a low level of consumption CL with cH > CL. Consider du(c) for the first derivative of the utility function with respect to dc du(c) dc2 du' (c) dc to be the second derivative of the utility function %3D (which is also the derivative of the first derivative of the utility function).

Question
Consider the lottery that assigns a probability T of obtaining a level of consumption CH
and a probability 1-T
an individual facing such a lottery with utility function u(c) that has the properties that
more is better (that is, a strictly positive marginal utility of consumption at all levels of
c) and diminishing marginal utility of consumption, u"(c) < 0. As usual, we are using
the shorthand u'(c) =
T of obtaining a low level of consumption CL with CH > CL. Consider
du(c)
for the first derivative of the utility function with respect to
dc
du(c)
du' (c)
consumption and u"(c)
(which is also the derivative of the first derivative of the utility function).
to be the second derivative of the utility function
dc
dc2
1. Provide a definition for the certainty equivalent level of consumption for the simple
lottery described above.
