Economic Inequality: Is it Natural?


  • Arnab Chatterjee
  • Sitabhra Sinha
  • Bikas K. Chakrabarti


Mounting evidences are being gathered suggesting that income and wealth distribution in various countries or societies follow a robust pattern, close to the Gibbs distribution of energy in an ideal gas in equilibrium, but also deviating significantly for high income groups. Application of physics models seem to provide illuminating ideas and understanding, complimenting the observations.
