\fIn a double decrement model with two independent decrements (causes), assume the following distributions for the exit times due to decrements 1 and 2 over one year from age x to age x +1: . Decrement 1: , px =1-tq, (uniform exit), 0 0 to derive an approximate formula for the expected present value EPV, of $1 under the policy payable to a policyholder currently aged x within one year at annual interest rate i in terms of x, qx, and 8 = log(1+ i) . Then calculate an approximate EPV of $10,000 payable to a policyholder of current age 55 within next two years, using qx in part (b) above, and i = 0.04. [5]A commercial real estate company has an option to develop a parcel of land. Assuming the dynamics of land value, L, are described by geometric Brownian motion with drift o and volatility o, and that the cost of developing the land is /, answer the following questions. Assume the economy is risk-neutral and the instantaneous risk-free rate of interest is r. a. Compute the value of the development option, F(L), and the optimal exercise policy, _", assuming the firm can exercise the option at any time. b. In a more realistic setting, the company may face competition that damages the value of its growth options. For simplicity, assume that the arrival of competition can be described as a Poisson process with intensity parameter 1; and that conditional on the arrival of competition, the development option becomes worthless (i.e., drops in value to zero). Compute the value of the option, F(L), and the optimal exercise policy, _" , under this competition scenario. c. Compare the optimal exercise policies under parts a. and b. of this question. How does competition influence the optimal exercise policy
