1. (15 points) Capital structure overlooks that firms have different capital requirements across their life cycle. In addition, the finance literature highlights various theoretical models that explain how the firms' life stages influence capital struc cture decisions, such as the Pecking Order, Trade-Off, and Agency Cost Theories. We like to know how firms in highly innovative industries have' different capital requirements over their life cycle.

【題組】(1) (5points) In the beginning of the life cycle, firms are more likely to raise funds through issuing equity or using borrowing, why?

2. (15 points) To construct a portfolio using the mean-variance framework, one needs cstimates of the expected return r, the variance  σ2i and the co-variance aj for each stocks, j. Forn stocks, you have to estimate a total of n(n-1)/2 correlation coefficients. Single index models are used, to reduce this hugc amount of needed estimates. Now we are going to construct a portfolio with two assets using the single index model.


【題組】

(1) (3 points) Please calculate the mean and variance of the stock index return and mean return for asset B.
61677abc923e6.jpg We run the following regression for each asset.

3.(10 points) The equity in a firm is a residual claim, i.e., equity holders lay claim to all cashflows left over after other financial claim-holders (debt, preferred stock ctc,) have been satisfied. Ifa firm is liquidated, the same principle applies, with equity investors receiving whatever is left over in the firm atter all outstanding debts and other financial claims are paid off. The principle of limited liability, however, protects equity investors in publicly traded firms if the value of the firm is less than the valuc of the outstanding debt, and they cannot lose more than their investment in the firm.

【題組】(1) (2 points) Beside the residual claim right mentioned above, what elise rights that an equity investor hold?

(2) (1.5 point) The payoff to equity investors, on liquidation, can therefore be written as: Payof61677e1ee684f.jpg
where, V = Value of the firm
 D = Facc Value of the outstanding debt and other external
 Please draw a figure of the payoff to equity investors (Y-axis) and the firr value (X-axis).

4. Consider a two-period economy (/ = 0, 1). The operating profit of firm j can be expressed as6167811ccf630.jpgis the exogenous profitability shock; At is a technology shook at time t;61678171c112c.jpg is private capital of fimm j. a > 0 is assumed. The depreciation rate of capital k for firm / is δj. Thus, the investment of firm6167835541711.jpg, firm j has a liquidation value of6167832856a3f.jpg. The investment in private capital involves adjustment cost 616782fcd02a5.jpg616782d89bb1a.jpg. The stochastic discount factor between time 0 and 1 is m, where log(m) = logβ + γ(x0 -x1), where 0 <β< 1, and γ> 0. Firm j then chooses ij.0 to maximize its value, which is the sum of the discounted cash flows from the two periods:6167821ea7df6.jpg E[.] is an expectation operator. From standard asset pricing equation, 616781e40bbea.jpg -Cov0(r1,m). Specifically, the cash flows from t = 0 are equal to the operating profit minus the investment cost and the adjustment cost. The cash flows from ! = I are equal to the operating profit plus the liquidation value.


【題組】(1) (10 points) Please drive FOC for maximum firm value, and express it as a form of marginal cost equal to marginal revenue.

21.【題組】

(2) (10 points) Note that the investment return616783c23f90d.jpg, defined as the ratio of marginal benefit to marginal cost of investment, is equal to the firm's stock return (rl) under equilibrium. Please show that 616783f5a825b.jpg

(3) (10 points) Please derive expected excess return:6167842564f69.jpg, which is a function of the covariance between the operating profit at t = 1 of firm y and the aggregate productivity shock.
