The Effects of Taxes on Wealth Inequality in Artificial Chemistry Models of Economic Activity

We consider a number of Artificial Chemistry models for economic activity and what consequences they have for the formation of economic inequality. We are particularly interested in what tax measures are effective in dampening economic inequality. By starting from well-known kinetic exchange models, we examine different scenarios for reducing the tendency of economic activity models to form unequal wealth distribution in equilibrium.

Rich or poor: Who should pay higher tax rates?

A dynamic agent model is introduced with an annual random wealth multiplicative process followed by taxes paid according to a linear wealth-dependent tax rate. If poor agents pay higher tax rates than rich agents, eventually all wealth becomes concentrated in the hands of a single agent. By contrast, if poor agents are subject to lower tax rates, the economic collective process continues forever.

经济互动和财富分配

Economic interactions and the distribution of wealth

本文分析了在企业生产率受到特殊冲击、要素收益率由竞争性市场决定、王朝具有线性消费函数、政府对资本和劳动收入征税并将收集到的资源平均再分配给王朝的经济中财富的均衡分配。财富的均衡分布是明确计算的，其形状主要取决于市场的不完全性。特别是，只有在资本市场不完全的情况下，上尾的帕累托定律才会出现。帕累托指数取决于储蓄率、资本净资本利润率、人口增长率和投资组合多样化。相反，劳动力市场的特点主要影响财富分配的底部尾部。分析还表明，增长与财富不平等之间存在正相关关系。

Effect of tax dynamics on linearly growing processes under stochastic resetting: a possible economic model

We study a system of $N$ agents, whose wealth grows linearly, under the effect of stochastic resetting and interacting via a tax-like dynamics -- all agents donate a part of their wealth, which is, in turn, redistributed equally among all others. This mimics a socio-economic scenario where people have fixed incomes, suffer individual economic setbacks, and pay taxes to the state. The system always reaches a stationary state, which shows a trivial exponential wealth distribution in the absence of tax dynamics. The introduction of the tax dynamics leads to several interesting features in the sta…
