内容简介

In this talk, I introduce our work on the discrete-time infinite horizon backward stochastic differential equation, i.e., infinite horizon backward stochastic difference equation. The well-posedness of this equation and the discrete-time stochastic recursive control problem is studied. By introducing a proper discrete-time infinite horizon dual equation, we prove the stochastic maximum principle and the verification theorem for this recursive control problem. Finally, we apply the derived stochastic maximum principle to the optimal consumption problem arisen from a type of long-term trust fund.
