1. There is one period. Assume a representative agent with utility function U(ct) = 1 − exp( −ηct). In parts c) through i) assume the following:
❼ η = .01 and δ = .97.
❼ Consumption at t = 0 is C0 = 25.
❼ At t = 1 one of two states θ 1 and θ2 eventuate with probability π 1 = .5, and π2 = .5, respectively.
❼ There are two complex securities s1 and s2 .
❼ s1 has a payoff of 23 in θ 1 and 27 in θ2 .
❼ s2 has a payoff of 21 in θ 1 and 31 in θ2 .
Answer the following:
(a) For what values of η is the utility function well behaved? (i.e. U\ > 0 and U\\ < 0) (b) Derive an expression for the stochastic discount factor mt+1?
(c) What are the prices q0(s)1 and q0(s)2 of complex securities s1 and s2 at t = 0?
(d) What weights create Arrow-Debreu securities? (hint: What are the weights of the complex securities that create payoffs (1, 0)\ and (0, 1)\ ?)
(e) What are the state prices q1 and q2 ? (hint: State prices are a function of prices from
part c) and the the inverse of the payoff matrix from part d).)
(f) What is the price of a risk free bond qb ?
(g) What are the risk neutral probabilities π 1(RN) and π2(RN)?
(h) Using the risk neutral probabilities solve for qs1 and qs2 .
(i) Is π 1(RN) greater than or less than the true probability π1 ? Why? (hint: See discussion on page 266 in the textbook.)
2. There are two bonds.Both bonds have a $1,000 face and mature 5 years from today. Bond A pays a 3% annual coupon and Bond B pays a 4% annual coupon. Bond A sells for $915.99 and Bond B for $960.14. Answer the following:
(a) What is r5 ?
(b) What is q5 ?
3. Assume the APT equation holds for three factors as follows:
❼ SMB with a factor beta of 0.9 with a factor risk premium of 6%.
❼ HML with a factor beta of 0.8 with a factor risk premium of 7%.
❼ MOM with a factor beta of 0.4 with a factor risk premium of 4%. Assume the following:
❼ The risk free rate is 5%
❼ A project requires an investment at t = 0 of 250.
❼ Expected Cash Flows of 100 eventuate at t = 1.
❼ Expected Cash Flows grow at 6% annually until t = 5.
❼ At t = 5 the project is shut down.
❼ There are no taxes or shut down costs.
Answer the following:
(a) Using the APT, what is the expected return?
(b) Using the expected return using the APT, what is the expected project NPV?
