Wealth distribution on complex networks.
We study the wealth distribution of the Bouchaud-Mézard model on complex networks. It is known from numerical simulations that this distribution depends on the topology of the network; however, no one has succeeded in explaining it. Using "adiabatic" and "independent" assumptions along with the central-limit theorem, we derive equations that determine the probability distribution function. The ...
متن کاملWealth Dynamics on Complex Networks
We study a model of wealth dynamics [Bouchaud and Mézard 2000, Physica A 282, 536] which mimics transactions among economic agents. The outcomes of the model are shown to depend strongly on the topological properties of the underlying transaction network. The extreme cases of a fully connected and a fully disconnected network yield power-law and log-normal forms of the wealth distribution respe...
متن کاملAsset-Exchange Model and wealth distribution
The scientific study of economic inequality has drawn a major interest due to the ever growing uneven distribution of wealth within the whole society. According to Oxfam International, in 2010, 388 individuals holds as much wealth as half of the world population. And this number has, in 2016, decreased to 62 individuals (Hardoon and Ayele, 2016). It is a very important but extremely hard proble...
متن کاملSharing the wealth: the effect of siblings on adults' wealth ownership.
Inequality in wealth has been well-documented, but its causes remain uncertain. Family processes in childhood are likely to shape adults' wealth accumulation, but these factors have attracted little attention. I argue that family size matters: children from larger families accumulate less wealth than do those from smaller families. Siblings dilute parents' finite financial resources and nonmate...
متن کاملWealth distributions in asset exchange models
A model for the evolution of the wealth distribution in an economically interacting population is introduced, in which a specified amount of assets are exchanged between two individuals when they interact. The resulting wealth distributions are determined for a variety of exchange rules. For “random” exchange, either individual is equally likely to gain in a trade, while “greedy” exchange, the ...
