基尼系数泰尔指数等几个公平性评价的介绍

Inequality increases as the disparity increases.
If a single person holds all of a given resource, inequality is at a maximum. If all persons hold the same percentage of a resource, inequality is at a minimum.
Inequality studies explore the levels of resource disparity and their practical and political implications.
Economic Inequalities can occur for several reasons:
Pros
• Easy to Understand • Easy to Compute
Cons
• Ignores all but two of
the observations
• Does not weight
observations
• Affected by inflation • Skewed by this example, the Range = $1,000,000-$24,000 = 976,000
Range
The range is simply the difference between the highest and lowest observations.

常用经济学中英文词汇解释

Equilibrium，competitive竞争均衡见竟争均衡（competitive equilibrium）。

Equilibrium，general⼀般均衡见⼀般均衡分析（general－equilibrium analysis） Equilibrium，macroeconomic宏观经济均衡意愿总需求等于意愿总供给的GDP⽔平。

在均衡时，意愿的消费（C），政府⽀出（G），投资（I）和净出⼝（X）的总量正好等于在当前价格⽔平下企业所愿意出售的总量。

Equimarginal principle等边际法则决定收⼊在不同消费品之间分配的法则。

消费者可按此法则选择消费组合，使花费在所有商品和服务上的每⼀美元的边际效⽤都相等，就能保证消费者所获得的效⽤化。

Exchange rate汇率见外汇汇率（foreign exchange rate） Exchange－rate system汇率制度国家之间进⾏⽀付时所依据的⼀组规则、安排和制度。

历最重要的汇率制度是⾦本位制、布雷顿森林体系和现在的浮动汇率制。

Excise tax vs.sales tax消费税和销售税消费税是对某种或某组商品，如酒和烟草的购买所课征的税。

销售税是对除少数特定商品（如⾷品）以外的所有商品所课征的税。

Exclusion principle排他原则私⼈品区别于公共品的⼀种性质。

当⽣产者将⼀种商品卖给A后，若能很容易地将B、C、D 等⼈排除在该商品益处享⽤过程之外，则排他原则就在发⽣作⽤，该商品也因此是⼀项私⼈品。

若不能轻易地把其他⼈排除在分享过程之外，如公共卫⽣或国防，则我们称该商品具有公共品的特征。

Exogenous vs.induced variables外⽣变量和引致变量外⽣变量是那些由经济体系以外的因素来决定的变量。

与外⽣变量相对应的是引致变量，后者是由经济体系的内在运⾏所决定的。

例如，天⽓变化是外⽣变量，⽽消费的变化则常常由收⼊变动所引致。

泰尔指数分析我国卫生资源地区分布公平性

泰尔指数分析我国卫生资源地区分布公平性泰尔指数的运用可以避免采用基尼系数时由于指数缺陷而产生的偏差,更为准确地衡量我国卫生资源地区分布的公平性。

本文首先使用泰尔指数从地区内部和地区之间两个方面分解我国不公平性产生的途径,然后综合两种途径对我国卫生资源地区分布的不公平性进行测算。

研究发现我国卫生资源地区间分布的公平性有所改善,而地区内部的不公平程度却有加剧的倾向,使得总体公平性的改善不明显;卫生硬件资源分布的公平性要优于软件资源。

标签：卫生资源公平性泰尔指数一、前言作为社会公平基本内容之一,卫生资源分布的公平意味着每一位社会成员拥有相同的机会获得医疗卫生服务,其直接体现社会公平,并对构建和谐社会产生重要的影响。

通过进行卫生服务资源公平性的研究,可以指导卫生资源合理配置,发现并保护弱势群体,进而促进建立卫生服务公平的动态监测与反馈机制等。

国内对卫生资源分布公平性已有一些研究,但是大部分研究文章停留在描述性分析的层面上,没有根据公平性指标对其进行量化。

部分研究采用了洛伦兹曲线(Lorenz Curve)和基尼系数(Gini Coefficient)来评价我国卫生资源分布的公平性,但是由于这两种测算方法存在着内在缺陷,分析结果往往与实际情况不完全相符。

本文通过泰尔(Theil)指数的运用,试图克服基尼指数分析的缺陷,较为深入地分析我国卫生服务资源的公平性。

文中所用到的全国各省地级市人口和卫生资源的数据资料来源于国家统计局国民经济综合统计司编写的《中国区域经济统计年鉴》2002、2004、2006和2008年卷。

二、研究方法与结果1.研究方法的说明关于公平性分析的指标,国外有一些文献采用公平性指数对卫生服务公平性进行分析。

Wagstaff 等(1991) 利用集中指数法衡量保健费用和健康状况分布的不公平性。

Doorslaer等(1994) 提出了一种使用各种患病率指标衡量健康不公平性的方法。

泰尔指数ev-概述说明以及解释

泰尔指数ev-概述说明以及解释1.引言文章1.1 概述：泰尔指数ev是一种常用的经济学指标，用于衡量一个国家或地区的财富或收入分配的不平等程度。

它是由意大利统计学家科雷多·泰尔（Corrado Gini）在1912年提出的。

泰尔指数通过计算财富或收入分布的不平等程度，可以帮助我们了解一个社会的公平性和社会经济发展的程度。

泰尔指数的值范围在0到1之间，值越接近0，表示财富或收入分配越均衡；而值越接近1，表示财富或收入分配越不平衡。

当泰尔指数为0时，意味着所有人的财富或收入都完全相同；当泰尔指数为1时，表明一个个体拥有了全部的财富或收入，而其他人没有任何财富或收入。

泰尔指数的计算方法相对简单，可以通过对个体财富或收入进行排序后，根据累计百分比计算得出。

具体来说，我们可以将财富或收入按照从小到大的顺序排序，然后计算累计百分比，最后根据泰尔指数的公式进行计算。

泰尔指数在各个领域都有广泛的应用。

在经济学领域，泰尔指数可以帮助研究者了解经济的公平性和稳定性情况，为制定经济政策提供参考。

在社会学领域，泰尔指数可以帮助我们了解财富或收入分配对社会的影响，揭示社会阶层和社会不平等问题。

在发展经济学领域，泰尔指数可以帮助我们比较不同国家或地区之间的财富或收入分配情况，从而进行国际比较和分析。

总而言之，泰尔指数ev作为一种重要的经济学指标，对于了解一个国家或地区的财富或收入分配的不平等情况具有重要意义。

通过计算泰尔指数，我们可以更好地了解社会经济的公平性和稳定性，为制定相关政策提供支持。

在未来，泰尔指数的应用领域还有待进一步拓展和研究，以更好地服务于社会经济的发展与进步。

1.2 文章结构文章结构部分的内容:文章分为引言、正文和结论三大部分。

对测量不平等的泰尔指数和基尼系数比较

对测量不平等的泰尔指数和基尼系数比较作者：刘续棵来源：《经济研究导刊》2014年第07期摘要：测量收入不平等以及研究贫困问题主要采用的两种方法就是利用基尼系数和泰尔指数。

基尼系数的计算本身存在三种最为常用的区别，而泰尔指数在组内组间分解上更优于基尼系数，但是由于其计算收入转移上的敏感性，使得其与基尼系数相比更可能高估不平等。

通过对比这两种计算方法，可以对不同的微观数据采用不同的方法。

关键词：基尼系数；泰尔系数；收入不平等中图分类号：F0 文献标志码：A 文章编号：1673-291X（2014）07-0012-03一、基尼系数的测量就衡量收入不平等而言，我们最为常用的方式就是使用基尼系数进行衡量。

从1921年基尼系数（Gini，1921）第一次出现到现在已经有八十年的历史（Xu，Kuan，2004），对基尼系数的研究和分析已经形成一套很成熟的方法和并积累了大量相关的文献。

在对基尼系数论述的的文献历史中，Anand （1983）和Chakravarty （1990）对包括基尼系数在内的不平等测量方法进行了全面的调查，Lambert （1989），以及Atkinson and Bourguignon （2000）也对利用基尼系数衡量收入不平等以及贫困问题提供了全面的参考文献。

对于基尼系数的发展历程及文献综述回顾可以参见Kuan Xu（2004），其根据以往的文献对基尼系数的产生和发展进行了一次全面的梳理，同时对基尼系数的解释，社会福利效应以及收入分解都做了详细的介绍。

在Kuan Xu（2004）的文章中，基尼系数定义为用来衡量收入、消费以及财产分配差异的指标。

对基尼系数的测量主要有三种方法：几何法、协方差法以及矩阵法。

（一）几何法对于几何法而言，主要是根据洛伦兹曲线来对基尼系数进行几何描述，其初始公式为：A：是洛伦兹曲线与完全平等曲线（45度线）之间的区域面积B：是洛伦兹曲线以下的区域面积以人口的累积百分比由低到高作为横坐标，由收入的累计百分比由低到高作为纵坐标。

基尼系数是国际上用来衡量收入分配差异状况的一个重要分析指标。

基尼系数国际上通常把0.4作为收入分配贫富差距的“警戒线”，认为0.4-0.6为“差距偏大”，0.6以上为“高度不平均”。

基尼系数低于0.2表示收入绝对平均，0.2-0.3表示比较平均，0.3-0.4表示相对合理，0.4-0.5表示收入差距较大，0.6以上表示收入差距悬殊.
巴西目前仍有1627万赤贫人口，占全国人口的8.5%
巴西2010年判断收入分配公平程度的基尼系数为0.5304，是自1960年有该项统计以来的最低值，表明巴西贫富差距明显缩小。

The Theoretical Basics of Popular Inequality MeasuresTravis Hale, University of Texas Inequality ProjectThis document explores several inequality measures used broadly in the literature, with a special emphasis on how to compute Theil’s T statistic. Inequality is related to several mathematical concepts, including dispersion, skewness, and variance. As a result, there are many ways to measure inequality, which itself arises from various social and physical phenomena. While this is not an exhaustive discussion of inequality measures, it does deal with several of the most popular statistics. Several examples are included that pertain to inequality of salaries within two fictional companies – Universal Widget and Worldwide Widget – but all of the inequality measures discussed apply to a broad set of research questions. The salary schedules for the example problems are below, followed by discussions of range, range ratios, the McLoone Index, the coefficient of variation, and the Gini Coefficient. Following these brief introductions is an extended description of Theil’s T statistic.RangePerhaps the simplest measure of dispersion, the range merely calculates the difference between the highest and lowest observations of a particular variable of interest. Strengths of the range include its mathematical simplicity and ease of understanding. However, it is a very limited measure. The range only uses two observations from the overall set, it does not weight observations by important underlying characteristics (like the population of a state, the experience of an employee, etc.), and it is sensitive to inflationary pressures. In the case of a company, the range between the salaries of the highest and lowest paid employees may not give much information. For Universal Widget, the range in salaries is $982,000 ($1,000,000 - $18,000), while for Worldwide Widget the range is $4,985,000 ($5,000,000 - $15,000). Does this mean that Worldwide Widget has a much more unequal wage structure than Universal Widget? Not without further evidence.Range RatiosTo find the range ratio for a certain variable, divide the value at a certain percentile (usually above the median) by the value at a lower percentile (usually below the median). One range ratio often used in the study of inequality in educational expenditures is the Federal Range Ratio, which divides the difference between the revenue for the student at the 95th percentile and the 5th percentile by the revenue for the student at the 95th percentile.1 Another popular range ratio is the inter-quartile range ratio. Subtracting the observation at the 25th percentile by the observation at the 75th percentile results in a quantity known as the inter-quartile range, and dividing the observation at the 75th percentile by the 25th percentile calculates the inter-quartile range ratio. Range ratioscan measure all sorts of inequalities and the percentiles can be constructed in any manner.A range ratio can take on any value between one and infinity, and smaller values reflect lower inequality.Using the example data, one can compute a 90:10 range ratio for the two widget companies. For Universal Widget, the 90th percentile falls at a salary of $60,000 and the 10th percentile is $25,000. Thus, the 90:10 range ratio is $60,000/$25,000 or 2.4. For Worldwide Widget, the 90th percentile falls at a salary of $35,000 and the 10th percentile is $30,000. Therefore, the 90:10 range ratio is $35,000/$30,000 or 1.17. Given this information, Worldwide Widget has a more equal pay structure, the opposite conclusion gleaned from the range.Range ratios are easy to understand and simple to compute. They can directly compares the “haves” - observations at the 90th percentile or elsewhere above the median value - with the “have-nots” - observations at the 10th percentile or elsewhere below the median, without being sensitive to outliers at the very top or very bottom of the distribution. However, like the range, range ratios only look at two distinct data points, throwing away the great majority of the data. Because of this significant limitation, researchers often employ more sophisticated inequality measures.McLoone IndexThe McLoone Index is another example of a measure that compares one part of a distribution to another. However, the McLoone Index takes a much larger proportion of the data into account. It compares how much of a resource is concentrated in the bottom half of a distribution to the median amount. To compute the McLoone Index value, divide the sum of all of the observations at or below the median level by the product ofthe number of observations at or below the median level and the value of the median level. Values of the McLoone Index are bound below by zero - if the lower half of the distribution receives none of the resource - and above by one - if there are no observations below the median. The latter case would occur if the lowest value is shared by at least half of the observations. Unlike most inequality measures, a higher value for the McLoone Index describes a more equitable distribution.For example, the Universal Widget Company has 400 employees. The median salary value is approximately that of the 200th least compensated employee. That employee is an Equipment Operator who makes $25,000. The McLoone Index is the ratio of the actual salaries of the least paid half of the Universal Widget workforce to the counterfactual denominator of $25,000 * 200 = 5,000,000. Thus the McLoone Index for Universal Widget equals (7*18,000 + 10*22,000 + 183*25,000) / 5,000,000 or .9842. Parallel computations reveal that Worldwide Widget has a McLoone Index valueof .9595. This leads to a conclusion that Universal has a more equal pay structure.The McLoone Index is relatively easy to understand, and might be an appropriate measure if researchers are primarily interested in the bottom of a distribution. If the median observation reflects an “adequate” level, th en the McLoone Index gives some sense of how the bottom half of the distribution is doing compared the middle. However, the McLoone Index has some potentially objectionable properties. First, it does not use all information, throwing away the observations above the median. Certainly there is a substantial difference between a distribution where the higher values lie just above the median and one where some observations lie far beyond the median. The McLoone Index compares reality with a counterfactual model, so the researcher may be asked tojustify the comparison of reality to an alternative where the entire bottom half of the distribution shares the median value. While the McLoone Index has thus far been concerned primarily with school finance inequality measurement, there are similar measures with broader application, and there is no reason that the McLoone Index itself could not be applied to other phenomena.The Coefficient of VariationThe coefficient of variation is simply the standard deviation of a variable divided by the mean.2 Graphically, the coefficient of variation describes the peakedness of a unimodal frequency distribution. For a dataset that is closely bunched around the mean, the peak will be high, and the coefficient of variation small. Data that is more dispersed will have a shorter peak and a higher coefficient of variation. Ceteris paribus, the smaller the coefficient of variation, the more equitable the distribution.The first step in computing coefficients of variation for the sample data is to find the mean and standard deviation of each set. This is fairly easy to do with statistics software, or a spreadsheet program such as Microsoft Excel. Universal Widget has an average salary of $36,452.50 and a standard deviation of 52,630.52. Worldwide Widget has an average salary of $38,773.08 and a standard deviation of 138,990.96. This leads to coefficients of variation of 1.44 and 3.58 for Universal and Worldwide, respectively, concluding that Universal has the more equitable salary structure.The coefficient of variation has some attractive properties. If group data is used, but weighted by population size, small outlying observations do not skew the distribution greatly. Individuals with even a limited statistical background are likely to be familiar with the standard deviation and sample mean, making the coefficient of variation easy to explain to a non-technical audience. Furthermore, by construction, inflation does not affect the coefficient of variation. A disadvantage of the measure is that, theoretically, the coefficient of variation can take any value between zero and infinity, and there is no universal standard that defines a reasonable value of the measure for particular phenomena.The Gini CoefficientThe Gini coefficient derives from the Lorenz Curve. To plot a Lorenz curve, rank the observations from lowest to highest on the variable of interest, and then plot the cumulative proportion of the population on the X-axis and the cumulative proportion of the variable of interest on the Y-axis.3 The Gini coefficient compares this cumulative frequency and size curve to the uniform distribution that represents equality. In thegraphical depiction below, a diagonal line represents perfect equality, and the greater the deviation of the Lorenz curve from this line, the greater the inequality. The Gini coefficient is double the area between the equality diagonal and the Lorenz curve, bounded below by zero (perfect equality) and above by one (the case when a single member of the population holds all of a resource).There are several ways to compute the Gini coefficient for a dataset. Researchers who are comfortable with Calculus and spreadsheet analysis and have a large amount of data that results in smooth plots can estimate a high order polynomial for the Lorenz Curve (Microsoft Excel will add up to a 6th degree polynomial as a trend line for an XY graph), and then take an appropriate integral to compute the size of the shaded area. Likewise, other estimation techniques, such as the method of rectangles, the method of trapezoids, or Monte Carlo integration will provide reasonable estimates. Another way tocompute the Gini is directly from an algebraic formula. Given that the data is ordered from smallest to largest values of the variable of interest, the formula is:12(21)'n ii i n x G n μ=--=∑, where i is the individual’s rank order number, n is thenumber of total individuals, x’i is the individual’s variable value, and μ is the population average.4To compute the Gini coefficients for the sample data, it is easiest to organize the data such that each individual is given his or her own record (such that the salaryschedule for Universal Widget has 400 rows, one for each employee). After splitting the data in this manner, it is fairly straightforward to apply the formula above. For Universal Widget, the Gini coefficient is 0.279625369, while for Worldwide Widget, the Gini coefficient is 0.227509252.The Gini coefficient is a full-information measure, looking at all parts of thedistribution. It is probably the most well-known and broadly used measure of inequality used in economic literature. The Gini coefficient facilitates direct comparison of two populations, regardless of their sizes. In other words, with the Gini coefficient one can directly compare the inequality in a classroom to the inequality in a country. While the actual computation of the Gini coefficient may include taking an integral or using a slightly complex formula, the visual description is elegant and easy to understand. The Gini coefficient does suffer from the lack of a true zero, and the need for a context.While a distributional policy, like giving everyone below the poverty line $1,000, has real implications, the repercussions of a 5% reduction of the Gini coefficient are much less clear.Theil’s T StatisticThe inequality measures discussed above are each appropriate in certain circumstances. The rationale for preferring Theil’s T statistic is not that there is som e inherent flaw in the other measures, but that Theil’s T has a more flexible structure that often makes it more appropriate. If a researcher always had access to complete, individual level data for the population of interest, then measures like the coefficient of variation or the Gini coefficient would usually be sufficient for describing inequality. However, in practice, individual data is rarely available, and researchers are asked to make due with aggregated data. Returning to the example problem illustrates the point. What if the Universal Widget salary schedule did not reflect the exact salary for each employee but the average salary over each job category? It would be possible to compute values for the coefficient of variation or the Gini coefficient under the assumption that each employee receives exactly the average salary, but the results would only give an upper or lower bound of each inequality measure, because variance within each job category will contribute to total inequality. For most practical data, data that has some degree of aggregation or an underlying hierarchy (e.g. cities within regions within nations), Theil’s T statistic is often a more appropriate and theoretically sound tool.5 The following formulae give the algebra behind Th eil’s T statistic. While these particular equations use income as the variable of interest, Theil’s T can address any number of quantifiable phenomena. When household data is available, Theil’s T statistic is6:]1[where n is the number of individuals in the population, y p is the income of the person indexed by p , and μy is the population’s average income. If every individual has exactly the same income, T will be zero; this represents perfect equality and is the minimum value of Theil’s T. If one individual has all of the income, T will equal ln n ; this represents utmost inequality and is the maximum value of Theil’s T statistic.If members of a population can be classified into mutually exclusive and completely exhaustive gro ups, then Theil’s T statistic is made up of two components, the between group element (T’g ) and the within group element (T w g ).[2]T = T’g + T w gWhen aggregated data is available instead of individual data, T’g can be used as a lower bound for the pop ulation’s value of Theil’s T statistic. The between group element of Theil’s T can be written as:]3[where i indexes the groups, p i is the population of group i , P is the total population, y i is the average income in group i , and μ is the average income across the entire population. T’g is bounded above by ln (P/p i (min)), the natural logarithm of the total population∑=⎪⎭⎪⎬⎫⎪⎩⎪⎨⎧⎪⎪⎭⎫ ⎝⎛⎪⎪⎭⎫ ⎝⎛⎪⎭⎫ ⎝⎛=np y p y p yy n T 1ln **1μμ∑=⎭⎬⎫⎩⎨⎧⎪⎪⎭⎫ ⎝⎛⎪⎪⎭⎫ ⎝⎛⎪⎭⎫ ⎝⎛=mi ii i g y y P p T 1ln **'μμdivided by the size of the smallest group. This value is attained when the smallest group holds all the resource. When data is hierarchically nested (i.e. every municipality is in a province and each province is in a country) Theil’s T statistic must increase or stay the same as the level of aggregation becomes smaller (i.e. T population ≥T’g (district) ≥T’g (county) ≥T’g (region)). Theil’s T statistic for the population equals the limit of the between group Theil component as the number of groups approaches the size of the population.Because the central purpose of this document is t o show how to use Theil’s T statistic, the examples relating to its use will be a little more involved.Example 1: Construct Theil’s T statistic for Universal Widget and Worldwide Widget with the data as given.A.First, consider Universal Widget. To follow along in Excel, open the spreadsheet “Example Problems with Theil’s T Statistic” and select the worksheet “Theil Example1A”. Since individual level data is available, Equation 1 is rele vant. The first step is to sum the number of employees and the total payroll and to divide total payroll by the number of employees to get the average salary. Next, compute the salary/average salary quotient for each salary level. Then, take the natural logarithm of the same quotient. An individual’s “Theil element” is the contribution that he or she makes to Theil’s T statistic. This value is computed as [1/n]*[salary/average salary]*[ln(salary/average salary)]. After computing the Theil elements for each job position, multiply by the number of employees in the position. Adding up these values yields the Theil Index, which in the case of Universal Widget is 0.28615395.B. To compute Theil’s T statistic for Worldwide Widget, follow the exact same st eps as in Part A. The computations can be found in the Excel spreadsheet “ExampleProblems with Theil’s T Statistic” under the worksheet “Theil Example 1B”. The result is a Theil’s T Statisti c value of 0.463162658.Analysis: Computing values for Theil’s T statistic is a relatively simple process of plugging values into a formula. The real concern is to make some conclusion about inequality. Is it possible to conclude that Worldwide Widget has a more unequal salary structure than Universal Widget because Worldwide has a higher value of Theil’s T statistic? Not necessarily. As discussed above, with individual data, the value of Theil’s T statistic is bounded by ln (n), so while Universal Widget has an upper bound of ln(400) = 5.991464547, Worldwide Widget has an upper bound ln(1300) = 7.170119543. Because Worldwide Widget has more employees, ceteris paribus it will have a greater value of Theil’s T statistic (in fact if the companies had identical Theil’s T statistic values, one could conclude that the larger company had less inequality). Generally speaking, values of Theil’s T statistic need a context to make sense. Given that last year’s Theil’s T statistic for salaries at Universal Widget was .1000, the Theil’s T statistic for salaries at Worldwide Widget was .5000, and both companies had workforces of similar size to their current levels, one could conclude that salary inequality increased at Universal and decreased at Worldwide over the last year. Knowing only this year’s information and that the two companies have significantly different sized workforces, it is difficult to make many substantive conclusions. If only one year’s worth of data is available, then another inequality measure, such as the Gini coefficient or coefficient of variation may be more appropriate.Example 2: What is the interpretation of Theil’s T statistic if the salary schedules given represent the average salary across positions, not the exact salaries?In other words, for Universal Widget, the 7 members of the Custodial Staff have an average salary of $18,000 per year, but this may fluctuate among individuals. Analysis: Looking at Equation 2, Theil’s T statistic is composed of a between group part and within group part. Under the assumptions of this problem statement, there is no way to compute the within group component, because there is no knowledge of individual salaries, only average salaries. However, it is possible to compute the between group component and note that this is the lower bound for total inequality. For this task, the proper mathematical relation is Equation 3, which by no accident bears a striking resemblance to Equation 1. Because the salary figures are the same, the numerical values of T heil’s T statistic do not change for either company, but the interpretation does. Now 0.28615395 represents the between group component of Theil’s T statistic for Universal Widget and the lower bound of total inequality. The spreadsheet analysis for both Universal and Worldwide can be found in the Excel Spreadsheet “Example Problems with Theil’s T Statistic” under the worksheets “Theil Example 2A” and “Theil Example 2B.” Notice how the column headings change, which changes the underlying interpretation of the calculations.Example 3:Consider the following data:Unlike examples 1A and 1B, employees draw different salaries based on both their level of seniority (entry, mid, senior) and their job position. Example 3 resumes the assumption from the first example that the data represents exact salary information for each individual.Given this new data, what is the Theil Index for Universal Widget?Answer: There are several ways to do this problem, and four solutions are worked out in the spreadsheet. The first solution (Theil Example 3A) starts by computing the within-group inequality for each job position (custodial staff, engineers, etc.). A Theil component is computed for each experience level within each job position, the summation of which gives within group inequality. However, before concluding how much the job position inequality contributes to total company-wide inequality, we must re-weight by the proportion of salaries within the job position. (In other words, inequality within the equipment operator group takes on greater weight than among the custodial staff, because 70% of workers operate equipment while less than 2% perform custodial services.) Computing the Theil Index in this manner helps us to parse total inequality into within-group and between-group components. The total value of the Theil Index is now 0.12860521, of which 0.124275081 is between-group inequality and0.004330129. The substantive lesson here is that the difference in average salaries between job positions causes the vast majority of the inequality, and the differences among seniority levels within job positions contribute very little to total inequality.Theil Example 3B calculates total inequality by comparing each job position-experience level combination to the average salary. The value of the total Theil Index is the same, but this method does not naturally parse the Index into within-group andbetween-group portions. Full enumeration - Theil Example 3C makes each employee a separate record, which, yet again, leads to the same value for the total Theil Index, but does not calculate the within group and between group portions.Alternative approach – compute the Theil Index by experience level instead of job positionAdvantages and Disadvantages of the Theil IndexThe principle disadvantage of the Theil index is that its values are not always comparable across different units (such as nations). If the number and sizes of groups differ, then limit of the index will differ. On the other hand, the Theil index has less stringent data requirements – group data is often easier to come by than individual survey data – and Theil index values can tell a rich story about inequality over different levels of aggregation…1 Given that all observations are ordered from lowest to highest, a percentile is merely the observation that is a certain portion away from the lowest value. If a company had 200 employees and listed their salaries from lowest to highest, the 5th percentile would be found at the 10th lowest observation (.05 * 200 = 10) and the 95th percentile would be found at the 190th lowest observation (or the 10th highest depending on your perspective; .95 * 200 = 190.) The median is the 50th percentile, or middle value.2The standard deviation is defined asNS=where X is the sample average and some texts substitute N for N –3For more information on Lorenz Curves, see the entry in Eric Weisstein’s World of Mathematics,/.Christian Damgaard, “Lorenz Curve.” Online.

泰尔指数和基尼系数的不同

泰尔指数和基尼系数的不同
泰尔指数和基尼系数是反映一个国家或地区收入分配不均的常用指标。

虽然两个指标都可以用于评估贫富差距，但它们之间的计算方式和含义有所不同。

泰尔指数是一种衡量收入不平等的方法，它根据不同收入群体的收入份额来计算。

具体来说，泰尔指数是最富裕的20%家庭收入占总收入的百分比与最穷困的20%家庭收入占总收入的百分比之差的一半。

如果这个差值越大，则泰尔指数越高，表明贫富差距越大。

而基尼系数则是另外一种测量收入不平等的方法，它是相对于每个人平均收入而言的。

基尼系数的范围在0到1之间，其中0表示完全平等，1表示完全不平等。

在这种计算方式下，基尼系数的计算与泰尔指数类似，但是不再仅仅考虑最富裕和最贫困的20%人口，而是将所有人口分成若干收入群体，然后根据每个群体在总收入中所占的比例来计算基尼系数。

总体来说，这两种指标的计算方式不同，但它们都可以用来评估一个国家或地区中收入分配是否公平。

在实际应用中，研究人员和政策制定者通常会综合使用这些指标来获得更准确的衡量结果，并采取措施来减少贫富差距的不平等。

stata 泰尔指数 -回复

stata 泰尔指数-回复Stata 泰尔指数概述泰尔指数（Theil index）是一种衡量收入或财富的不平等程度的统计指标，经常被用来描述一个经济体中不同个体或群体之间的收入分配差异。

它是由经济学家Horst Theil于1967年提出的，也被称为Theil-T指数。

在实际应用中，Stata是一个非常流行的统计软件，被广泛用于计量经济学、社会科学等领域的数据分析。

泰尔指数的计算方式泰尔指数的计算方式有多种，常见的有两种：Theil T指数和Theil L指数。

其中，T指数是一个输入位阶比奥编程相关的指数，用来衡量泰尔不等度，而L指数是以连续性变量作为输入的指数，它是基于信息熵和基尼系数的计算方法。

在Stata中，可以使用“ineqdeco”命令来计算泰尔指数。

该命令是由StataCorp开发的，它通过最大熵原理来尽可能准确地估计泰尔指数。

以下是在Stata中计算泰尔指数的具体步骤：步骤1：导入数据首先，我们需要将要分析的数据导入Stata。

可以使用Stata的“import”命令将数据从外部文件导入到Stata中。

例如，如果数据保存在名为“data.csv”的CSV文件中，可以使用以下命令导入数据：import delimited "data.csv", clear步骤2：生成变量接下来，我们需要使用Stata的“generate”命令生成所需的变量。

对于泰尔指数的计算，我们需要生成两个变量：一个变量表示个体的收入或财富水平，另一个变量表示个体的权重。

例如，假设我们的数据集中有一个名为“income”的变量表示收入，以及一个名为“weight”的变量表示个体的权重。

我们可以使用以下命令生成这两个变量：generate income = .replace income = <Income Value> if <Condition>generate weight = .replace weight = <Weight Value> if <Condition>请将<Income Value>和<Weight Value>替换为相应的具体数值，以及<Condition>替换为收入和权重的条件。

gini基尼系数·全英文介绍

Measuring inequality:the Gini Index 1Math 128–Fall 2005Introduction Most people would agree that “good things,”such as money income,should be more or less equally distributed.In practice,of course,good thingsare not evenly distributed,and so it’s useful to have a numerical measure of inequality.We might,for instance,watch such a measure over several years to decide whether equity is increasing or decreasing.The Gini Index (GI)is such a measure.It is widely used used by economists to measure and compare income equality in various countries,or in a given country over time.A GI of 0.00corresponds to perfect equality—everyone has exactly the same income.A GI of 1.00corresponds to perfect in equality—one person gets all the income and everyone else gets nothing.No real-world society has perfect income equality (or complete inequality),and there are good political,moral,and economic arguments to be had about how much income equality is “best”in a given society.Calculating the Gini Index mathematically does not settle these arguments—the disagreements are philo-sophical,not just mathematical.But knowing the Gini Index can lend some quantitative weight to the discussion.GI information is easy to ﬁnd on the Web.Here,for instance,are some rough GI data on family income in various countries,culled from the CIA World Factbook.(The GI is reported here as a percent ,ranging from 0to 100.)Denmark24.7Russia 39.9Japan24.9China 40.0Sweden25.0United States 40.8Kazakhstan35.4Honduras 56.3Portugal35.6Brazil 60.7Ireland 35.9Sierra Leone 62.9The Lorenz curve The GI is deﬁned in terms of the so-called Lorenz curve ,or Lorenz function ,which we’ll denote by L (x ).The Lorenz function is deﬁned as follows:If 0≤x ≤1,then L (x )is the fraction of all income received by the lowest-paid fraction x of the population.Observe:•L (0.31)=0.23means that the “poorest”31%of the population receive 23%of the income;•L (1/2)=1/3means that the poorest half of the population get one-third of the income.•None of the expressions L (−23),L (1.2),and L (0.3)=213makes good sense.(Do you see why not?)•For every income distribution,we have L (0)=0and L (1)=1.The Lorenz curve is the graph of the Lorenz function.Note that,in a perfectly egalitarian system,we would have L (x )=x for all x (1/2of the people would have 1/2of the income,and so on)and so the Lorenz curve is just the 45-degree line y =x .Deﬁning the Gini Index The Gini Index can be deﬁned in several ways.Here is a deﬁnition in calculus language:The Gini Index is twice the area between the Lorenz curve and the line y =x .In symbols:GI =2 10(x −L (x ))dx (The factor 2may seem 1Some ideas here come from Bruce Teague,North Carolina School of Science and Mathematics.1equationand deciles In real-world situations we can’t know L(x) for every possible fraction x.What is often available(and tabulated by governments)is information on income quintiles and(sometimes)income deciles.For quintiles,a population is divided into equal-sized ﬁfths,ranging from the poorestﬁfth to the richestﬁfth.(For deciles the population is divided into tenths.) For example,the following table shows such data for two diﬀerent years in the US:Share of income(percent)by quintileYear poorest second third fourth richest1968 4.211.117.524.442.81992 3.89.415.824.246.9The data in each row can be used toﬁnd several values of the Lorenz function for a given year.For1968, we have L(0.2)=.042,L(0.4)=.042+.111=.153,and L(0.8)=.042+.111+.175+.244=.572.This process lets usﬁnd six values of L(x):L(0)=0,L(0.2),L(0.4),L(0.6),L(0.8),and L(1)=1.By “connecting the dots”between these values we can approximate the full Lorenz curve,and use the result to “see”the area that deﬁnes the GI.We can also use the function values and the trapezoid rule to estimate 1(x−L(x))dx,which appears in the GI.the integralOn the Web Here are two Web sources;“googling”willﬁnd many more./~dhenwood/Gini_supplement.html /hhes/income/histinc/ie3.html ProblemsDo as many as you can manage from among the following problems;some are open-ended or non-mathematical.1.Is equal distribution of income the“best”policy for a society?Why or why not?2.Explain brieﬂy in money language why,for every Lorenz curve,(i)L(0)=0;(ii)L(1)=1;(iii)L(x)≤x,for all x;(iv)L(x)is an increasing function.13.Explain why the alternative formula GI=1−2L(x)dx can also be used to calculate the GI.4.Suppose we know L(0)=0,L(0.2),L(0.4),L(0.6),L(0.8),and L(1)=1for a particular population.Give a formula for using the trapezoid rule to estimate the GI.(Use some sigma notation.)5.Calculate the GIs for the two years1968and1992for which quintile data are given above.(Use yourformula from the preceding problem.)In which year was there“more inequality”?6.A powerful genie(genie...get it?)grants a wish and doubles everybody’s income.How does this aﬀectthe GI?7.Another genie,not to be outdone,adds$1million to everybody’s income.How does this aﬀect the GI?8.Suppose we have income decile information,and therefore know L(0)=0,L(0.1),L(0.2),...,L(0.9),and L(1)=1for a particular population.Give a formula for using the trapezoid rule to estimate the GI.(Use sigma notation.)9.For which positive numbers n could L(x)=x n possibly be a Lorenz function?For such values of n,what is the GI?What happens as n gets very large?10.Mother Hubbard’s ten children receive weekly allowances(in dollars)of1,1,1,2,2,4,4,5,8,10.Calcu-late a reasonable GI for the Hubbard children.(Use deciles.)211.Suppose that10people have incomes i1,i2,i3,...,i10,listed in increasing order.How would youmimic the GI formula above(which involves an integral)to calculate the GI for this small group? ment on the table above that shows the family income GIs for various countries.Do low-GIcountries have something in common?Do high-GI countries?13.Some politicians assert that income inequality has been increasing in recent years.Do the data and GIcalculations support this claim?(See /hhes/income/histinc/ie3.html.)If so,can you suggest any reasons?14.Do rich countries usually have higher(or lower)GIs than poor countries,or is there no clear pattern?Look on the Web for data to support your claim.15.The GI is based on the idea that,in some sense,the“perfect”income distribution has Lorenz functionL(x)=x.Suppose that for some reason we decide to consider a distribution with Lorenz function L(x)=x2as“perfect.”Then,we might measure“imperfection”using a new,improved quantity,sayIGI(for Improved Gini Index),deﬁned by IGI=1x2−L(x)2dx.(The square in the integrandlets us forget about the sign of any diﬀerence.)(a)Comment on this notion of perfection,and on the IGI formula.Is either reasonable?(b)Calculate the IGI for the two years1968and1992discussed above.In which year was there more“imperfection”?3。
