A General Model for Continuous Time Principal-Agent Problem Under Hidden Action

Jaeyoung Sung, Jianfeng Zhang, Zimu Zhu

In this paper, we study a general continuous-time Principal-Agent (PA) problem, where the agent privately makes effort and consumption decisions over time under a contract with pay…

Is a sophisticated agent always a wise one?

Jianfeng Zhang

For time inconsistent optimal control problems, a quite popular approach is the equilibrium approach, taken by the sophisticated agents. In this short note we construct a determini…

Minimal solutions of master equations for extended mean field games

Chenchen Mou, Jianfeng Zhang

In an extended mean field game the vector field governing the flow of the population can be different from that of the individual player at some mean field equilibrium. This new cl…

From finite population optimal stopping to mean field optimal stopping

Mehdi Talbi, Nizar Touzi, Jianfeng Zhang

This paper analyzes the convergence of the finite population optimal stopping problem towards the corresponding mean field limit. Building on the viscosity solution characterizatio…

A Dynamic Principal Agent Problem with One-sided Commitment

Jianfeng Zhang, Zimu Zhu

In this paper we consider a principal agent problem where the agent is allowed to quit, by incurring a cost. When the current agent quits the job, the principal will hire a new one…

Mean Field Games of Controls: Propagation of Monotonicities

Chenchen Mou, Jianfeng Zhang

The theory of Mean Field Game of Controls considers a class of mean field games where the interaction is through the joint distribution of the state and control. It is well known t…
