T = 2) Suppose that we are considering a model in which the volatility is stochas- tic and is independent from the underlying process. For example, in an easy case we could postulate that o can take two values on (0, T): 01 with probability p 02 with probability 1 - p. How would you price a call in this situation? (We talked about this in class. Now, assume that the choice of 0 or 02 is done for the whole period. In other words, each path has either volatility 01 or 02 between 0,T].) ={ T = 2) Suppose that we are considering a model in which the volatility is stochas- tic and is independent from the underlying process.
