# Question: Using Monte Carlo simulate the process dr a b

Using Monte Carlo, simulate the process dr = a(b − r)dt + σ√rdZ, assuming that r = 6%, a = 0.2, b = 0.08, φ = 0 and σ = 0.02. Compute the prices of 1-, 2-, and 3-year zero coupon bonds, and verify that your answers match those of the Cox- Ingersoll-Ross formula. What numerical problem can arise in this simulation? How did you address it?
