Talk Title: Optimal precommitment strategies in some time-inconsistent control problems
Series: CommNetS
Abstract: Time-inconsistency is a feature of a dynamic optimization problem which causes the Dynamic Programming Principle to fail. This arises in many applications including dynamic optimization of certain risk measures (e.g., conditional value-at-risk, mean-variance, etc.) and problems whose objective function depends non-linearly on an expected value. There are various interpretations and notions of solution to a time-inconsistent problem. In this talk, we focus on optimal precommitment strategies in continuous-time and demonstrate cases where the time-inconsistent problem may be re-written as an optimization problem over the value function of an auxiliary time-consistent optimization problem. While the auxiliary value function typically has a higher dimensional state space, we discuss instances where structure of the problem allows a dimensionality reduction.
