We consider an optimal investment problem proposed by Bielecki and
Pliska. The goal of the investment problem is to optimize the long-term
growth of expected utility of wealth. We consider HARA utility functions
with exponent $-\infty< \gamma< 1$. The problem can be reformulated as
an infinite time horizon risk-sensitive control problem. Some useful
ideas and results from the theory of risk-sensitive control can be used
in the analysis. Especially, we analyze the associated dynamical
programming equation. Then an optimal (or approximately optimal)
Markovian investment policy can be derived.
