Galam, Serge; Walliser, Bernard - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 3, pp. 481-489

The 2-spin Ising model in statistical mechanics and the 2×2 normal form game in game theory are compared. All configurations allowed by the second are recovered by the first when the only concern is about Nash equilibria. But it holds no longer when Pareto optimum considerations are introduced...

Economics requires understanding and analyzing forces that bring buyers and sellers to a market place who then negotiate exchanges of goods and services based on a mutually agreeable price. Economists have their own method of modeling whereby models are first conceived of some notion of economic...

Formation of share market prices under heterogeneous beliefs and common knowledge

Biondi, Yuri; Giannoccolo, Pierpaolo; Galam, Serge - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 22, pp. 5532-5545

Financial economic models often assume that investors know (or agree on) the fundamental value of the shares of the firm, easing the passage from the individual to the collective dimension of the financial system generated by the Share Exchange over time. Our model relaxes that heroic assumption...

The geometrical patterns of cooperation evolution in the spatial prisoner's dilemma: An intra-group model

Oliveira dos Santos Soares, Ricardo; Martinez, … - In: Physica A: Statistical Mechanics and its Applications 369 (2006) 2, pp. 823-829

The prisoner's dilemma (PD) deals with the behavior conflict between two agents, who can either cooperate (cooperators) or defect. If both agents cooperate (defect), they have a unitary (null) payoff. Otherwise the payoff is T for the defector and null for the cooperator. The temptation T to...

Evolutionary dynamics of nationalism and migration

Barreira da Silva Rocha, André - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 15, pp. 3183-3197

I present a dynamic evolutionary game model to address the relation between nationalism against immigrants and assimilation of the latter into the host country culture. I assume a country composed of two different large polymorphic populations, one of native citizens and the other of immigrants....

Thermodynamics of relation-based systems with applications in econophysics, sociophysics, and music

Gündüz, Güngör - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 20, pp. 4637-4653

A methodology was developed to analyze relation-based systems evolving in time by using the fundamental concepts of thermodynamics. The behavior of such systems can be tracked from the scattering matrix which is actually a network of directed vectors (or pathways) connecting subsequent values,...

Introduction to statistical physics outside physics

Stauffer, Dietrich - In: Physica A: Statistical Mechanics and its Applications 336 (2004) 1, pp. 1-5

We review the possibilities and difficulties for statistical physicists if they apply their methods to biology, economics, or sociology. WARNING: I report opinions, not simulations.
