Abstract: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 richer individual gains. When the amount of asset traded is fixed, random exchange leads to a…

The Rich Are Different ! Pareto Law from Asymmetric Interactions in Asset Exchange Models
It is known that asset exchange models with symmetric interaction between agents show either a Gibbs/log-normal distribution of assets among the agents or condensation of the entire wealth in the
Multiplicative asset exchange with arbitrary return distributions
The conservative wealth-exchange process derived from trade interactions is modeled as a multiplicative stochastic transference of value, where each interaction multiplies the wealth of the poorest
Wealth condensation in a multiplicative random asset exchange model
Abstract. Random Asset Exchange (RAE) models, despite a number of simplifying assumptions, serve the purpose of establishing direct relationships between microscopic exchange mechanisms and
Modeling wealth distribution in growing markets
Abstract.We introduce an auto-regressive model which captures the growing nature of realistic markets. In our model agents do not trade with other agents, they interact indirectly only through a
Analysis of wealth inequality with a random money transfer model
Increasing gap in wealth distribution is among the key issues that have been discussed worldwide in recent years. In this paper, we use the money transfer model to explain the formation of wealth
A Stochastic Model of Wealth Distribution
A major research focus in economics and econophysics is on the distribution of wealth in societies at different stages of development. Wealth includes money, material goods and assets of different
Population and Asset Distributions in Economically Competitive Activities: a Rate-Equation Approach
We introduce a simple asset migration model for the wealth redistribution in economical activities, in which a unit of asset migrates from one individual to another whenever they interact. By means

Physics Today.
Using a combination of x-ray diffraction and electron diffraction, the scientists produced a three-dimensional map of the hybridized "orbital hole" bonding copper with neighboring oxygen atoms in cuprite (Cu2O).
How nature works: The science of self-organized criticality
His ruthless simplifications of geology, evolution, and neurology pay off because his models describe behavior that is common across these domains, and this universality means that trampling across others turf is not only acceptable, but almost mandatory, if the underlying principles are to be exposed.
