Abstract:
Household portfolios include risky bonds, beyond stocks, and respond to permanent labor income shocks. This article brings these features into a life-cycle setting, and shows that optimal stock investment is constant or increasing in age before retirement for realistic parameter combinations. The driver of such inversion in the life-cycle profile is the resolution of uncertainty regarding social security pension, which increases the investor’s risk appetite. This occurs if a small positive contemporaneous correlation between permanent labor income shocks and stock returns is matched by a realistically high degree of risk aversion. Absent this combination, the typical downward-sloping profile obtains. Overlooking differences in optimal investment profiles across heterogeneous workers results in large welfare losses, in the order of 15–30% of lifetime consumption.
