# Existence and Asymptotic Behavior of an Optimal Barrier for an Optimal Consumption Problem in a Brownian Model with Absorption and Finite Time Horizon

Existence and Asymptotic Behavior of an Optimal Barrier for an Optimal Consumption Problem in a... We consider the following optimal control problem: Maximize $\mathbb{E}( \int_{(0,\tau)}e^{-\beta s}\,dC_{s}+e^{-\beta\tau}X_{\tau})$ , where X t = x + μt + σW t − C t , τ ≡inf{ t >0| X t =0}∧ T , T >0 is a fixed finite time horizon, W t is standard Brownian motion, μ , σ are constants, and C t describes accumulated consumption until time t . It is shown that the optimal strategy is given by a barrier strategy with time-dependent continuous barrier b ( t ). Moreover we determine the asymptotic behavior of b ( t ) for t → T . http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Mathematics and Optimization Springer Journals
