# Question

Consider the widget investment problem outlined in Section 17.1. Show the following in a spreadsheet.

a. Compute annual widget prices for the next 50 years.

b. For each year, compute the net present value of investing in that year.

c. Discount the net present value for each year back to the present. Verify that investing when the widget price reaches $1.43 is optimal.

Again consider the widget investment problem in Section 17.1. Verify that with S = $50, K = $30, r = 0.04879, σ = 0, and δ = 0.009569, the perpetual call price is $30.597 and exercise optimally occurs when the present ...You drawthese five numbers randomly from a normal distribution with mean−8 and variance 15: {−7, −11, −3, 2, −15}. What are the equivalent draws from a standard normal distribution? Suppose x1∼ N(2, 0.5) and x2 ∼ N(8, 14). The correlation between x1 and x2 is −0.3. What is the distribution of x1+ x2? What is the distribution of x1− x2? Assume S0 = $100, r = 0.05, σ = 0.25, δ = 0, and T = 1. Use Monte Carlo valuation to compute the price of a claim that pays $1 if ST > $100, and 0 otherwise. (This is called a cash-or-nothing call and will be further ...The Black-Scholes price for a European put option with S = $40, K = $40, σ = 0.30, r = 0.08, δ = 0, and t = 0.25 is $1.99.
