【題組】 ⑶說明 TE 偏振與 TM 偏振產生全透射（100% transmission）的條件。（6 分）
4. Consider a two-period economy (/ = 0, 1). The operating profit of firm j can be expressed as
is the exogenous profitability shock; At is a technology shook at time
t;
is private capital of fimm j. a ＞ 0 is assumed. The depreciation rate of capital k for firm / is
δj. Thus, the investment of firm
, firm j has a liquidation
value of
. The investment in private capital involves adjustment cost 
. 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:
E[.] is an expectation operator. From standard asset pricing equation, 
-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】
(3) (10 points) Please derive expected excess return:
, which is a function of the
covariance between the operating profit at t = 1 of firm y and the aggregate productivity shock.
