财富分配和集体知识。玻尔兹曼方法

Wealth distribution and collective knowledge. A Boltzmann approach

Lorenzo Pareschi, Giuseppe Toscani

摘要:

我们介绍并讨论了一个非线性动力学方程的玻尔兹曼型,它描述了知识的影响,在财富的演变在一个系统中的代理人,相互作用,通过二进制的行业在科迪埃,帕雷斯基,托斯卡尼,J.统计。Phys. 2005.交易包括储蓄倾向和市场风险,在这里,风险和储蓄参数被修改,现在假设这些参数取决于个人的知识程度。数值模拟表明,知识的存在有可能产生一类富有的代理人,并占更大比例的财富不平等。

英文摘要:

We introduce and discuss a nonlinear kinetic equation of Boltzmann type which describes the influence of knowledge in the evolution of wealth in a system of agents which interact through the binary trades introduced in Cordier, Pareschi, Toscani, J. Stat. Phys. 2005. The trades, which include both saving propensity and the risks of the market, are here modified in the risk and saving parameters, which now are assumed to depend on the personal degree of knowledge. The numerical simulations show that the presence of knowledge has the potential to produce a class of wealthy agents and to account for a larger proportion of wealth inequality.
