Define the risk premium p = č - Cce where č level of consumption from the lottery (7 = E[c]). Consider the following exercise. There are three lotteries characterized by different probabilities of obtaining CH. Let these probabilities be given by r" > T' > T. Using a single diagram, plot the risk premium for each of these three lotteries. Does the risk premium increase or = TCH + (1 – T)CL is the expected decrease as we increase T across these three lotteries? Provide the intuition for your result.

Define the risk premium p = ċ – Cce where c = TCH + (1 – T)CL is the expected
level of consumption from the lottery (7 = E[c]). Consider the following exercise.
There are three lotteries characterized by different probabilities of obtaining cH-
Let these probabilities be given by a" > T' > n. Using a single diagram, plot the
risk premium for each of these three lotteries. Does the risk premium increase or

decrease as we increase across these three lotteries? Provide the intuition for
your result.

Consider the lottery that assigns a probability of obtaining a level of consumption Ch
and a probability 1-7 of obtaining a low level of consumption c1 with cH > CL. Consider
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
for the first derivative of the utility function with respect to
du(c)
dc
du(c)

consumption and u" (c)
(which is also the derivative of the first derivative of the utility function).
