摘要:
This paper investigates a multi-period investment-consumption problem where the discount function is quasi-hyperbolic and the exit probability is dynamically evaluated over time in view of the subjective information of the decision-maker. The problem is time-inconsistent due to the quasi-hyperbolic discount function and the updated exit probability over time, so we obtain the investment-consumption strategy under the framework of Nash equilibrium. We find that the quasi-hyperbolic discount function can essentially change the consumption pattern, and the investors with low risk aversion and low bequest utility are sensitive to the change of the quasi-hyperbolic discount function. For the effects of the exit probability, we obtain the conditions under which the consumption proportion is increasing along with the exit probabilities evaluated at the current time. By numerical analysis, the effects of the exit probabilities evaluated at each time on the consumption strategy and the expected wealth process are studied.
