Portfolio Problems with Logarithmic Utility and Stochastic Interest Rates (I)

摘要：

This paper concerns with portfolio problems with logarithmic utility where an investor can invest in a savings account, stocks, and bonds, trying to maximize her utility from terminal wealth. We focus on the case where the short interest rate is stochastic. Dynamic programming principle is used to reduce the underlying problem to a stochastic control problem, therefore the standard method from stochastic control is used to obtain the value function and the optimal investment strategy under the assumption that short interest rate takes two special forms resulting from HoLee and Vasicek model, respectively.
