# Question: Consider a one period binomial model with h 1 where

Consider a one-period binomial model with h = 1, where S = $100, r = 0.08, σ = 30%, and δ = 0. Compute American put option prices for K = $100, $110,$120, and $130.

a. At which strike(s) does early exercise occur?

b. Use put-call parity to explain why early exercise does not occur at the other strikes.

c. Use put-call parity to explain why early exercise is sure to occur for all strikes greater than that in your answer to (a).

Repeat Problem 11.4, only set δ = 0.08. What is the lowest strike price at which early exercise will occur? What condition related to put-call parity is satisfied at this strike price? Use a spreadsheet to verify the option prices in Examples 12.1 and 12.2. Assume r = 8%, σ = 30%, δ = 0. In doing the following calculations, use a stock price range of $60-$140, stock price increments of $5, and two different times to expiration: 1 year and 1 day. Consider purchasing a ...Let S = $120, K = $100, σ = 30%, r = 0, and δ = 0.08. a. Compute the Black-Scholes call price for 1 year to maturity and for a variety of very long times to maturity. What happens to the price as T →∞? b. Set r = ...Repeat Problem 13.10 for a 365-day 40-strike put.Post your question
