AI总结:

研究经济不平等与流动性的负相关关系,通过分析动能模型中参数对流动性的影响,验证其负相关性。

摘要:

对社会科学研究中的动能模型中社会流动性进行统计评估更具挑战性,因为这需要跟踪个体收入至少一代或两代的演变。在基于动能方程的微观到宏观经济交换理论模型中,收入分布仅取决于渐近平衡解,而流动性估计还涉及模型过渡概率的详细结构,因此是评估其有效性的关键工具。实证数据显示经济不平等与流动性之间存在显著的负相关关系,其解释仍不明确。因此,特别有趣的是在分析模型中研究这种相关性。在先前的工作中,我们研究了Gini不平等指数在动能模型中对定义二元相互作用和税收与再分配过程的几个参数的行为:储蓄倾向、税收差距、逃税率、福利资格审查等。在此,我们通过分析流动性依赖于相同参数来检查流动性与不平等的相关性。根据几个数值解,证实了这种相关性为负。

英文摘要:

Statistical evaluations of the economic mobility of a society are more difficult than measurements of the income distribution, because they require to follow the evolution of the individuals' income for at least one or two generations. In micro-to-macro theoretical models of economic exchanges based on kinetic equations, the income distribution depends only on the asymptotic equilibrium solutions, while mobility estimates also involve the detailed structure of the transition probabilities of the model, and are thus an important tool for assessing its validity. Empirical data show a remarkably general negative correlation between economic inequality and mobility, whose explanation is still unclear. It is therefore particularly interesting to study this correlation in analytical models. In previous work we investigated the behavior of the Gini inequality index in kinetic models in dependence on several parameters which define the binary interactions and the taxation and redistribution processes: saving propensity, taxation rates gap, tax evasion rate, welfare means-testing etc. Here, we check the correlation of mobility with inequality by analyzing the mobility dependence from the same parameters. According to several numerical solutions, the correlation is confirmed to be negative.
