Description: This is an in-depth look at the root causes of the subprime mortgage crisis and ways actuaries can eliminate the problems. From the Actuary Magazine, April/May 2010 – Volume 7 Issue 2.

Description: In this paper we investigate three investment-consumption problems for a risk averse investor: i an investment only problem that involves utility from only terminal wealth, ii an investment-consumption problem that involves utility from only consumption, and iii an extended investment-consumption problem that involves utility from both consumption and terminal wealth. We model these problems under a multiperiod setup that incorporates three types of uncertainties: the economic environment uncertainty, the asset return uncertainty, and the mortality uncertainty. By using dynamic programming, analytical expressions of the optimal investment consumption strategies to these problems are derived. Some economic implications on these results are also discussed.
