Envy as a source of exchange in a multiagent systemElena Ramirez and •Juan Guillermo Diaz Ochoa — Fachbereich 1, University of Bremen, Otto Hahn Allee, D-28359 Bremen

The use of statistical mechanics has changed the way in we understand, how the market dynamics is defined. The basic assumption is the existence of stochastic forces that govern a stock of exchanges. A first approach to this kind of systems is using its similitude with the concept of brownian motion. However, a market shows a critical behavior related with a kind of self organization. For example, the Donangelo-Sneppen model is a method which describes a market showing self organization by means of interaction rules defined by particular constrains for each individual.

However, real markets concern individuals that not only trade using a preference list but also try to increase their individual welfare. In such case, envy is an additional force that influences a network of trading agents. In this model we implement the dynamics of envious agents to the dynamics of trading agents in order to observe the effect of forced reallocations to achieve a welfare state.
