Cognitive economics and modelling of cultural dynamics
Objectives:
These researches aim at modeling social cognition as information processing distributed on a population of agents. One of the main objectives is to provide a formal framework, metamimetic games, for the modeling of endogenous preferences.
Metamimetic games build on the fact that metacognition and human reflexive capacities are the ground for a new class of mimetic rules, that enables to endogenize the distribution of imitation rules while being human specific. The corresponding concepts of equilibrium — counterfactually stable state — and attractor have been proposed.
This lead to an interpretation of social differenciation in terms of cultural co-evolution among a set of possible motivations, which departs from the traditional view of optimization indexed to immutable criteria that exist prior to the activity of agents.
Key words :
Social cognition, complex systems, social networks, endogenous preferences, imitation, reflexivity, metacognition, stochastic game theory, cultural co-evolution, social differenciation.

Emergence of Cooperation and endogenous networks
Objectives
- Propose new model of emergence of cooperation in heterogenous population,
- Take these stylised social dilemma to propose model of endogenous social networks formation.
Aggregated phenomena in social sciences and economics are highly dependent on the way individuals interact. To help understanding the interplay between socio-economic activities and underlying social networks, these researches present a model of sequential prisoner’s dilemma with binary choice.
An analytical and computational insight is performed about the role of endogenous networks in emergence and sustainability of cooperation and exhibits an alternative to the choice and refusal mechanism that is often proposed to explain cooperation.
Keywords : emergence of cooperation, endogenous social networks, selection of interactions, evolutionary games, heterogeneous agents.
