This
work studied and developed pension fund management strategies in a DC scheme,
during the distribution phase. The Pension plan member (PPM) is allowed to
invest in a risk-free and a risky asset, under the constant elasticity of
variance (CEV) model. The constrained optimization program was developed and
transformed into a nonlinear partial differential equation, using the
associated Hamilton Jacobi Bellman equation. The explicit solution of the
constant relative risk aversion (CRRA) is obtained, using Legendre transform,
dual theory, and change of variable methods. It is established herein, with a
proposition that the elastic parameter, ?, say, must not necessarily be equal
to one (?≠1). A theorem is constructed and proved on the pension wealth
investment strategy. Through a sensitivity analysis, we exposed the dangers of
CRRA utility options during the period after retirement. A numerical simulation
was used to buttress our investigation.
