Overview

In 1995, Chakrabarti was involved in the first Kolkata Econophysics Conference, discussed below.

In 2003, Chakrabarti, in his “Money in Gas-Like Markets: Gibbs and Pareto Laws”, coauthored with Arnab Chatterjee and S.S. Manna, considered ideal-gas models of trading markets, where each agent is identified with a gas molecule and each trading as an elastic or money-conserving (two-body) collision. Unlike in the ideal gas, they introduce a quantity the “saving propensity” $λ of agents, such that each agent saves a fraction $λ of its money and trades with the rest. They show that steady-state money or wealth distribution in a market is Gibbs-like for relation $λ = 0, has a non-vanishing most-probable value for $λ ≠ 0, and Pareto-like when $λ is widely distributed among the agents. They compare these results with observations on wealth distributions of various countries. [1]

In 2005, Chakrabarti was a coeditor of

Education

Chakrabarti completed his PhD in physics, thesis: "Critical Behaviour of Annealed Disordered Systems" in 1979 at Saha Institute of Nuclear Physics, Calcutta University and in 1983 became a physics professor at Saha Institute of Nuclear Physics. Currently, Chakrabarti is a visiting economics professor at the Indian Statistical Institute.

**Bikas Chakrabarti**(1952-) is an Indian physicist noted for 1995 to present work in econophysics and sociophysics, associated with what the formation of the Indian school of econophysics or what Russian-born American physicist Victor Yakovenko refers to as the “__Kolkata school__” of econophysics, a group which includes Indian physicist Anirban Chakraborti.

In 2005, Chakrabarti was a coeditor of

*Econophysics of Wealth Distribution*, with chapters themed on the Pareto principle of wealth distribution of Italian engineer and socioeconomist Vilfredo Pareto, and in 2006 was coeditor of*Econophysics and Sociophysics*, with its two noted thermodynamic formulation of socioeconomics by German physicist Jurgen Mimkes. [2]In 2013, Chakrabarti coauthored

*Sociophysics: an Introduction*, with chapters general social system modelling theory, social choice and popularity, crowd dynamics, etc., and six part appendix on topics including: phase transition, critical phenomena, magnetic systems, random walks, and Monte Carlo simulation. [4]Education
