PLEASE USE R CODE TO SOLVE
pricing an arithmetic mean Asian call option for a stock modeled by a geometric Brownian motion with an initial price of $100, a volatility of 40%, and zero interest rate. Let the expiry time be 12 weeks in the future (consider 52weeks a year), and let the monitoring frequency be weekly. The strike price is $110
a) Estimate the arithmetic mean Asian call option price using simple Monte Carlo method. What is the 99% confidence interval? b) Estimate the arithmetic mean Asian call option price using the discounted payoff of the geometric mean Asian call option as the control variate. [Hint: The exact price for a geometric mean Asian option is given in Lecture note 6.]. What is the 99% confidence interval? c) Estimate the arithmetic mean Asian call option price using the discounted payoff of the European call option as the control variate. What is the 99% confidence interval? d) Which method gives the narrowest confidence interval [i.e., smallest estimation error]? Can you explain why?
