Question

Suppose that Monte Carlo simulation is being used to evaluate a European call option on a non-dividend-paying stock when the volatility is stochastic. How could the control variate and antithetic variable technique be used to improve numerical efficiency? Explain why it is necessary to calculate six values of the option in each simulation trial when both the control variate and the antithetic variable technique are used.

Step 1

The control variate technique is a variance reduction method that involves introducing a correlated variable, called the control variate, into the simulation. The control variate is chosen such that its expected value is known and close to the value of the option Show more…
