International audience; We study repeated zero-sum games where one of the players pays a certain cost each time he changes his action. We derive the properties of the value and optimal strategies as a function of the ratio between the switching costs

Regularity of dynamic opinion games

Autor: Xavier Venel

Publikováno v: Games and Economic Behavior. 126:305-334

We analyze a class of stochastic games where two lobbies compete by influencing the opinions in a society. We assume that the opinions evolve according to De Groot opinion formation and that the decisions of the lobbies change the structure of the ne

History-dependent Evaluations in Partially Observable Markov Decision Process

Autor: Xavier Venel, Bruno Ziliotto

Publikováno v: SIAM Journal on Control and Optimization. 59:1730-1755

We consider partially observable Markov decision process (POMDPs) in which the weight of the stage payoff depends on the past sequence of signals and actions occurring in the infinitely repeated pr...

Decomposition of games: some strategic considerations

Autor: Nikolaos Pnevmatikos, Joseph Abdou, Marco Scarsini, Xavier Venel

Orthogonal direct-sum decompositions of finite games into potential, harmonic and nonstrategic components exist in the literature. In this paper we study the issue of decomposing games that are strategically equivalent from a game-theoretical point o

Diffusion in large networks

Autor: Michel GRABISCH, Agnieszka RUSINOWSKA, Xavier VENEL

Publikováno v: Journal of Economic Dynamics and Control. 139:104439

We investigate the phenomenon of diffusion in a countably infinite society of individuals interacting with their neighbors in a network. At a given time, each individual is either active or inactive. The diffusion is driven by two characteristics: th

Sequential Competition and the Strategic Origins of Preferential Attachment

Autor: Antoine Mandel, Xavier Venel

Publikováno v: SSRN Electronic Journal.

There exists a wide gap between the predictions of strategic models of network formation and empirical observations of the characteristics of socio-economic networks. Empirical observations underline a complex structure characterized by fat-tailed de

Recursive games: uniform value, Tauberian theorem and the Mertens conjecture ' $$Maxmin=\lim v_n=\lim v_{\uplambda }$$ M a x m i n = lim v n = lim v λ '

Autor: Xiaoxi Li, Xavier Venel

Publikováno v: International Journal of Game Theory. 45:155-189

We study two-player zero-sum recursive games with a countable state space and finite action spaces at each state. When the family of n-stage values $$\{v_n,n\ge 1\}$$ is totally bounded for the uniform norm, we prove the existence of the uniform valu
