A rigorous explanationART-2012-75912In simulations of some economic gas-like models, the asymptotic regime shows an exponential wealth distribution, independently of the initial wealth distribution given to the system. The appearance of this statistical equilibrium for this type of gas-like models is explained in a rigorous analytical way.2012http://zaguan.unizar.es/record/17031310.1016/j.jmaa.2011.07.060http://zaguan.unizar.es/record/170313oai:zaguan.unizar.es:170313JOURNAL OF MATHEMATICAL ANALYSIS AND APPLICATIONS 386, 1 (2012), 195-204All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
