Precommitted Investment Strategy versus Time-Consistent Investment Strategy for a Dual Risk Model by Lidong Zhang, Ximin Rong, Ziping Du

“…We compare the precommitted strategy with time-consistent strategy and find that these different strategies have different advantages: the former can make value function maximized at the original time t=0 and the latter strategy is time-consistent for the whole time horizon. Finally, numerical analysis is presented for our results.…”
