Here, a new functional equation is proposed in an economic context to explain the wealth exponential distribution. Concretely, the new iteration [1] given by Mathematical equation: [ecuación] It is found that the exponential distribution is a stable fixed point of this functional iteration equation. From this point of view, it is easily understood why the exponential wealth distribution (or by extension, other kind of distributions) is asymptotically obtained in different multi-agent economic models.2012http://zaguan.unizar.es/record/17031410.1051/proc/201236015http://zaguan.unizar.es/record/170314oai:zaguan.unizar.es:170314ESAIM: Proceedings and Surveys 36 (2012), 189-196All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
