Strategic advantages in mean field games with a major player
[Avantages stratégiques dans des jeux à champ moyen avec un agent majoritaire]
Comptes Rendus. Mathématique, Tome 358 (2020) no. 2, pp. 113-118.

Cette note porte sur une problématique de modélisation issue de la théorie des jeux à champ moyen. On montre comment il est possible de modéliser des jeux à champ moyen avec un agent majoritaire qui a un avantage stratégique, tout en restant dans un cas où on ne considère que des stratégies markoviennes en boucles fermées pour tous les joueurs. Nous illustrons ce fait autour de trois exemples.

This note is concerned with a modeling question arising from the mean field games theory. We show how to model mean field games involving a major player which has a strategic advantage, while only allowing closed loop markovian strategies for all the players. We illustrate this property through three examples.
