The dynamics is governed by a kinetic equation, which allows for self-similar solutions. The scaling function has a power-law tail, the exponent being given by a transcendental equation. In the limit of continuous trading, closed form of the wealth distribution is calculated analytically.8 pages 5 figuresStatistical MechanicsDisordered Systems and Neural NetworksGeneral Financetext
