Synopsis
Summary:
This dissertation thesis analyses solutions to a fully non-linear
Hamilton-Jacobi-Bellman equation arising from the problem of optimal investment portfolio
construction
that encounters a risk sensitive future pensioner, a typical participant of
the private defined-contribution based Second pillar of the Slovak pension
system.
We show how the Hamilton-Jacobi-Bellman equation can be converted using the
Riccati transform into a Cauchy-type quasi-linear parabolic differential
equation
and solve the associated parametric convex optimization problem. The weak
solution
to the studied problem is approached by its double asymptotic expansion
with respect to small model parameters and utilized to build the analytical
model
which serves us to estimate the investor's optimal pension fund selection
strategy.
We provide the analysis of the optimal policy from qualitative as well as
quantitative
point of view and formulate main policy implications and recommendations
that are applicable for all policy makers, pension fund managers, and the
Second
pillar participants.
Finally, we bring to model to Slovak data and illustrate how the optimal
investment
strategies and saver's expected terminal wealth accumulated on his/her
pension
account change depending on model calibration and its key parameters.
