We consider an optimal investment-consumption portfolio optimization model in which an investor receives stochastic dividends. As a first problem, we allow the drift of stock price to be a bounded function. Next, we consider a stochastic volatility model. In each problem, we use the dynamic programming method to derive the Hamilton-Jacobi-Bellman equation, which we proceed to prove existence of a classical solution. Our value function is chosen to maximize the expected total discounted HARA utility of consumption. In the Verification Theorem, we prove that the solution to the HJB equation is equal to the value function.
