【摘要】： 财富分布问题的研究具有很长的历史。尤其是财富分布的公平性问题,一直以来都倍受经济学家的关注。本文以货币转移模型为出发点。货币转移模型的特点是将货币从现实经济中抽象出来,只考虑财富与个体,从而建立多个体相互作用模型,进而进行计算机模拟,然后分析结果、考察财富本身的运行规律。在此类模型中,相互作用变现为财富在个体间的转移,而财富转移方式由建立的交易规则决定,因此具有简单,可扩展性强的特点。本文的另一基本出发点是在带有利他主义的货币交换模型下讨论财富分布的模型,其由R.Trigaux提出。之后,M.Rodrlguez-Achach和R.Huerta-Quintanilla等人对其做了详细分析,发现只有在不合理的高度利他条件下,才能得到一个更公平的社会财富分布。本文第一章介绍了个体及基于个体的模拟的概念,特点及意义。第二章介绍了货币转移模型的提出理念及几种重要的货币转移模型。在第三章中,介绍了引入利他主义的模型,研究了在此模型下,社会财富分布公平程度的变化并对衡量社会财富公平程度的指标-Gini系数进行了介绍和解释。基于前三章,本文于第四章提出了引入回扣的财富分布模型。在此模型中,将回扣机制引入了交易规则中,将个体用财富,道德,权力来进行定义。研究了此规则下,Gini系数的变化,Gini系数与回扣率之间的关系,社会财富分布情况以及在此规则下社会道德水平的情况。发现对每个回扣率,相应的Gini系数都趋于稳定,得到了回扣率-Gini系数曲线,发现当回扣率小于0.58时,回扣率越大Gini系数越小,从而越利于社会财富分配的均衡性,但当回扣率大于0.58时,回扣率的增大就不利于财富的均衡性了,但总体来说,引入回扣后Gini系数都比没有回扣时低,说明回扣有利于社会财富的均衡性。本文还定义了一个与Gini系数类似的道德系数来衡量社会道德水平的差别,发现引入回扣后社会道德水平随着时间增加差别越来越大。开展这方面的研究,可以了解回扣这种现象对社会财富分布的影响。
[Abstract]:The study of wealth distribution has a long history. In particular, the fairness of wealth distribution has been concerned by economists all the time. This paper takes the money transfer model as the starting point. The characteristic of the money transfer model is that the money is abstracted from the real economy, and only wealth and individual are considered, so the multi-individual interaction model is established, and then the computer simulation is carried out, and then the results are analyzed, and the running law of wealth itself is investigated. In this kind of model, the interaction is the transfer of wealth between individuals, and the way of wealth transfer is determined by the established transaction rules, so it has the characteristics of simplicity and expansibility. Another basic starting point of this paper is to discuss the model of wealth distribution under the currency exchange model with altruism, which is proposed by R.Trigaux. Then M. Rodrlguez-Achach and R.Huerta-Quintanilla et al made a detailed analysis and found that only under unreasonable and highly altruistic conditions can a fairer distribution of social wealth be obtained. The first chapter introduces the concept, characteristics and significance of individual and individual-based simulation. The second chapter introduces the concept of money transfer model and several important money transfer models. In the third chapter, we introduce the altruistic model, study the change of social wealth distribution fairness and explain the Gini coefficient, which is the index of social wealth equity. Based on the first three chapters, this paper puts forward the wealth distribution model with kickback in chapter 4. In this model, the rebate mechanism is introduced into the transaction rules, and the individual is defined by wealth, morality and power. The relationship between Gini coefficient and rebate rate, the distribution of social wealth and the social moral level under this rule are studied. It is found that for each kickback rate, the corresponding Gini coefficient tends to be stable, and the Gini coefficient curve of rebate rate is obtained. It is found that when the rebate rate is less than 0.58, the larger the rebate rate is, the smaller the Gini coefficient is, and the better the balance of social wealth distribution is. However, when the rebate rate is greater than 0.58, the increase of rebate rate is not conducive to the equilibrium of wealth, but generally speaking, the Gini coefficient after the introduction of rebate is lower than that without rebate, which indicates that rebate is beneficial to the equilibrium of social wealth. This paper also defines a moral coefficient similar to the Gini coefficient to measure the difference of social moral level. It is found that the difference of social moral level increases with time after the introduction of kickback. Carry out this research, you can understand the phenomenon of kickbacks on the distribution of social wealth.
