23 Mar 2016 Mean field games (MFG) provide a theoretical frame to model socioeconomic systems. In this Letter, we study a particular class of MFG that 

We consider a mean field game (MFG) of optimal portfolio liquidation under asymmetric information. We prove that the solution to the MFG can be characterized in terms of a forward-backward stochastic differential equation (FBSDE) with a possibly singular terminal condition on the backward component or, equivalently, in terms of an FBSDE with a finite terminal value yet a singular driver.

It can be solved by focusing on the optimal policy of a representative player in response to the behavior of the entire population. Let X and A be finite sets representing respectively the state and action arXiv:1905.13357v1 [cs.LG] 30 May 2019 1 Reinforcement Learning for Mean Field Game Nilay Tiwari, Arnob Ghosh, and Vaneet Aggarwal Purdue University We consider a mean field game (MFG) of optimal portfolio liquidation under asymmetric information.

In Section 7.2 of Chapter 7, we make some interesting remark about monotonicity in the context of Mean Field Games and displacement convexity. For instance, there exists a function F: P 2(M) 7!R which is convex along geodesic paths in P 2(M), while F is concave along traditional paths t!(1 t) 0 + t 1: Mean Field Games I A mean field game seeks to model the behavior of a very large number of small interacting agents that each seek to optimize their own value function. 2 15 Variational Mean-Field Games I Namely for some mean-field games, the Mean field games and Mean field type control introduce new problems in Control Theory. The terminology “games” may be confusing. In fact they are control problems, in the sense that one is interested in a single decision maker, whom we can call the representative agent. 2017-12-20 · These game situations, also referred to as mean-field-type games, involve novel equilibrium systems to be solved. Three solution approaches are presented: (ⅰ) dynamic programming principle, (ⅱ) stochastic maximum principle, (ⅲ) Wiener chaos expansion.

We propose a new approach to mean field games with major and minor players. Our formulation involves a two player game where the optimization of the representative minor player is standard while the major player faces an optimization over conditional McKean–Vlasov stochastic differential equations. The definition of this limiting game is justified by proving that its solution provides

MFG: basic theory. Generalizations of modeling. A mean field game is a situation of stochastic ( dynamic)  finite N-players game theoretic methods is often intractable.

Mean Field Games (MFG for short) are dierential games, with a continuum of players, usually considered all indistinguishable and all negligible. We typically consider congestion games (i.e.
