In statistical physics, the conservation of particle number results in the equalization of the chemical potential throughout a system at equilibrium. In contrast, the homogeneity of utility in socio-economic models is usually thought to rely on the competition between individuals, leading to Nash equilibrium. We show that both views can be reconciled by introducing a notion of chemical potential in a wide class of socio-economic models, and by relating it in a direct way to the equilibrium… Expand

The City as a Complex System. Statistical Physics and Agent-Based Simulations on Urban Models
Social and natural sciences share an interest for collective phenomena, which constitute an important part of the domain of complex systems. This thesis focuses on the study of urban systems, usingExpand
Dynamical fluctuations in a simple housing market model
We consider a simple stochastic model of a urban rental housing market, in which the interaction of tenants and landlords induces rent fluctuations. We simulate the model numerically and measure theExpand
Theoretical approaches to the steady-state statistical physics of interacting dissipative units
The aim of this review is to provide a concise overview of some of the generic approaches that have been developed to deal with the statistical description of large systems of interacting dissipativeExpand
Investigating land-use and transport interaction with an agent-based model.
We present an agent-based model grounded in the standard urban economics framework, using microeconomic interactions between heterogeneous agents who trade-off between housing costs and transportExpand
From the Physiocrats to Fairness in Nations
In this review, work from three centuries of biophysical economics is presented, starting from the physiocrats’ early work in biophysical economics in 1755, to the most recent modeling of modernExpand
The Society-Deciders Model and Fairness in Nations
Modeling the dynamics in nations from economical and sociological perspectives is a central theme in economics and sociology. Accurate models can predict and therefore help all the world's citizens.Expand
Commentary on “Biophysical Economics” and Evolving Areas
In this Issue, papers in the area of socio-econo-physics and biophysical economics are presented. We have recently introduced socio-econo-physics and biophysical economics in Biophysical Reviews andExpand
Exploring Social Phenomena with Complex Systems Tools
This thesis explores the problems raised by the aggregation of entities into a global, collective level, an old problem encountered in many fields of science. We work on three projects related to theExpand
Exploring the polycentric city with an agent-based model
We present an agent-based model grounded in the Alonso, Muth, Mills (AMM) framework, using microeconomic interactions between heterogeneous agents and able to reach the equilibrium in a dynamic way.Expand
Are Socio-Econo-Physical Models Better to Explain Biases in Societies?
In this work, we review various dynamical models in socio-econo-physics, and discuss their roles in understanding socio-economic biases. We deal with fairness in nations, wealth distributions in na...
