Suppose that G is a function of a stock price, S and time. Suppose that σs and og are
the volatilities of S and G. Show that when the expected return of S increases by Aos, the
growth rate of G increases by AoG, where A is a constant.
Let Y denote the present value of a ten-year deferred 30-year temporary life annuity-
immediate on (30). If i = 0 and mortality is uniformly distributed with w =
= 100,
calculate the probability that the sum of the payments will exceed E(Y).
A individual, with a utility function lnW and an initial wealth level W0, is faced with a fair gamble of winning or losing $h (where W0 > h > 0) with 50-50 chance. (a) Is this individual risk averse? Explain.(b) Suppose that the individual is willing to pay up to an amount of f in order to avoid such a gamble. Give the equation that determines f, and solve the equation for f (i.e., express f in terms of W0 and h). (c) Show that f increases as h increases.
