7. Risk aversion. Suppose that you took part in a lottery that had a chance to increase, decrease, or
have no effect on your level of income. With probability 0.5, your income remains at its original
level, $500. With probability 0.2, your income increases to $700, and with probability 0.3, your
income decreases to $400. Your utility function is
u(I) = 10.7,
where I denotes your income level.
(a) Using only the utility function, show that your risk preferences are risk averse.
(b) Calculate both your EU and the utility equivalent of the EV of your income.
(c) Using the results from part (b), show that your risk preferences are risk averse.
(d) Suppose now that you had the option to either accept this lottery, or walk away with your initial
$500. Should you accept the lottery? Why or why not?
