Abstract

We consider a singular stochastic control problem arising from continuous-time investment and consumption with capital gains tax, where the associated Hamilton-Jacobi-Bellman (HJB) equation admits many solutions. We show that the value function corresponds to the minimal viscosity solution of the HJB equation. Moreover, we prove by an explicit construction that the optimal strategy can be approximated by a sequence of sub-optimal strategies with bounded control. As far as we know, this is the first paper to explicitly construct such approximations in the singular control literature.
