Introduction to Income Redistribution Policies 收入再分配政策介绍 Michele Raitano (Sapienza University of Rome) 罗马一大 Training Programme “Effects and Tendency of Income Redistribution Policy” “收入再分配政策的调节效果和调整趋势”赴意大利培训 Italy, October 14th-28th, 2018 2018年10月14-28日 意大利
Outline 大纲 Why focusing on distribution 为什么聚焦分配 The concept of wellbeing to be considered and pros and cons of the income concept 需要考虑幸福的概念以及收入概念的正反两方面 The steps of the process of income distribution and the role of pre-distributive and redistributive policies 收入分配过程的环节,以及预分配和再分配政策的功能 Trend of income inequality and redistribution in OECD countries OECD国家收入不平等和再分配趋势 How to measure income redistribution 怎样衡量收入再分配 Main drivers of income inequality trends 收入不平等趋势的主要驱动因素 Main policies to deal with income inequality: predistribution and redistribution 应对收入不平等的主要政策:预分配和再分配
The focus on income distributions 收入分配的重点 Analyzing distribution of living standards is crucial in terms of both processes determining it (e.g., why are individuals differently paid?) and its consequences on some aggregate outcomes (e.g., growth, health, social cohesion). 分析生活标准的再分配是很关键的,收入分配过程决定了生活标准(如为什么个人得到的收入不同?),并且其结果对一些总体成果也很关键(如经济增长、医疗卫生、社会凝聚力)。 Which is the best variable for identifying individual welfare? 确定个人福利的最佳变量是什么? Monetary or non monetary indexes? Mono or multidimensional indexes? 货币或非货币指标?单一指标或多维度指标? Income. 收入 Consumption. 消费 Wealth. 财富 Functionings and capabilities (Sen). 功能性和能力 Happiness. 快乐
Income as the proxy of economic wellbeing 收入是经济福利的替代值 Income is the flow of a stock of wealth (physical, financial and human capital). 收入是一笔财富的流动(物质、财务和人力资源) Monetary and non monetary flows have to be considered. 需要考虑货币或非货币流动 The “Full income” concept (Simons 1938): consumption plus change in wealth => potential consumption. “全收入”概念(Simons 1938年):消费加财富变化=> 潜在消费 Is it possible to exactly compute all income components? 可能精确地计算所有收入构成部分吗? Usually, from “full” to disposable income (only considering personal income taxes and cash welfare benefits). 通常来说,从“全”收入到可支配收入(只考虑个人所得税和现金福利待遇) What does this imply in comparisons across countries and across times? 跨国家和跨时间比较的含义是什么
Limits in measuring «full income» 衡量全收入的局限性 Empirically it is very difficult to measure all income components: 从实证角度来说,很难衡量所有收入构成部分: Self-employment and business incomes. 自雇和经营收入 Capital gains and changes in asset values. 资产所得和资产价值的变化 Unpaid work => market price or opportunity cost approach? 无偿工作=>市场价格或机会成本方法? Fringe benefits. 附加福利 Imputed rents from housing. 住房的估算租金 In kind welfare transfers: long term care, education, health care (e.g. actual consumption or individual probabilities to be treated?). 实物型福利转移:长期护理、教育、医疗卫生(如实际消费或个人受到医疗服务的概率?)
The steps of personal income distribution (a) 个人收入分配的环节(一) From individuals to households (using equivalence scales); from distribution to redistribution. 从个人到家庭(使用均等比);从分配到再分配。 Individual labour earnings: 个人劳动收入 Hourly wages, time of work, unemployment spells. 小时工资,工作时长,失业持续时间 Household (equivalised) market incomes: 家庭的市场收入 Household composition (number of components, ages); 家庭结构(家庭成员的人数和年龄) Employment rates (number of income recipients); 就业率(有收入人员的数量) Non labour earnings. 没有劳动收入的人员 Household (equivalised) disposable incomes: 家庭的可支配收入 Detracting personal taxes and adding cash transfers. 去除个人税,加上现金转移支付 How to impute in kind benefits, imputed rents, tax expenditures, consumption taxes? Usually not considered => disposable instead than full income 怎样估算实物福利,怎样估算租金,怎样估算税项支出和消费税?通常来讲不考虑=>可支配收入代替全收入 Different mechanisms of inequality in the various steps. 不同的环节有不同的应对不平等的机制 Public policies can act in all steps => redistrib. or predistrib.? 可以在所有的环节采取公共政策=>再分配或预分配?
The steps of personal income distribution (b) 个人收入分配的环节(二) Different mechanisms of inequality acting (interacting or in contrast each other) in the various steps. 不同的环节具有不同的应对不平等的机制(之前相互联动或相反) Public policies clearly affect distribution through redistributive measures (tax & transfers, despite the difficulty of considering on income taxes, tax expenditures and in kind transfers). 公共政策通过再分配措施明显影响了分配(税收和转移支付,虽然很难计算收入税、 税项支出和实物转移) However, all public policies affect distribution changing markets equilibria in the first two steps (e.g., changing labour market institutions or through employment policies). 但是,所有对分配产生影响的公共政策在前两个环节改变了市场均衡(如改变了劳动 力市场的体制或通过就业政策) => Public policies can act in all steps: Redistribution and predistribution 所有环节都可以采取公共政策:再分配和预分配

The left side limits 限制和不足 Which reference population? 参考人口是哪些? 2. Incomes or “economic resources”? 收入或“经济来源”? How to measure redistribution? 怎样衡量再分配?
1. Reference population 参考人口 Generally core labor force population - aged 25-59 - is used for: 一般来说,核心劳动人口在25-29岁之间,主要用于: Data availability; 数据的可获得性 Emphasis on earnings; 重点在于薪资 More focus on “true” vertical transfers; 更多的针对“真实的”纵向转移支付 Too much emphasis on poverty reduction and transfers effects if the whole population is considered; 如果考虑全部人口,重点将会过多的放在扶贫和转移支付效果上 But this approach has many drawbacks: 但是这种方法也存在很多不足: The median voter is getting older; 中位选民的年龄增大 Comparability among countries with different elderly employment rates; 老年人就业率不同的国家间的可比较性 Pension transfers are not simply actuarial: many different distributive channels, depending on formulas and requirements; 养老金转移支付不仅是简单的精算:根据计算公式和资格要求,有很多不同的分配渠道 The need to analyze the many distributive effects of pension reforms; 需要分析养老保险改革的分配效应 A weak correlations between pension system generosity and pre-transfer poverty. 养老体系的发放金额和转移支付前的贫困率存在较弱的正向关联
2. Incomes or economic resources 收入或经济来源 Standard analysis focus only on “market” and “disposable” income; 标准分析的重点只是“市场”和“可支配”收入 To evaluate the redistributive WS effects and its tendencies, in-kind benefits and tax expenditures have to be added. 分析福利制度的再分配效应及其发展趋势,需要增加实物福利和税项支出 But how to impute in-kind transfers? 但是怎样估算实物转移支付 Which are the counter-factual of tax expenditures, their link with the private schemes spreading and their distributive channels? 税项支出的反事实有哪些?与私营体系普遍化及其分配渠道的联系是什么? In addition: 加上 Transfers have to be considered net of taxes; 对于转移支付,需要考虑纳税后净额 In a resource perspective, disposable income should be corrected also by indirect taxes (sometimes used to finance WS). 在来源方面,应当根据间接税修正可支配收入(一些时候为福利体系提供资金) Towards a “full (extended) income” concept? 迈向一个“全(延伸)收入”概念?
3. How to measure redistribution? 怎样衡量再分配? The first studies used public social spending as dependent variable, but it is a very poor proxy of redistribution (it is an input!) 首次进行的研究使用公共社会支出作为因变量,但是这是一个很差的再分配替代值(这是一个输入变量!) The more recent studies focus on outcomes measures, computing redistribution by a “Pre” and “Post” approach – based on Gini index, but there are some caveats: 最近开展的研究重点是成果衡量,根据基尼指数,通过“前”和“后”的方法计算再分配,但是也存在一些需要注意的地方: Gini index empathizes middle class transfers; 基尼指数较倾斜于对中产阶级的转移支付; In a counterfactual logic “Pre” is different from “In the Absence of”; WS effects have to be evaluated in every step of the distributive path. 在反事实逻辑中,“前”与“缺少”不同;分配过程中的每一个步骤都应评估福利体系的效果; And using Gini, the absolute difference or the percentage change? Is there a level effect? Are there diminishing returns in inequality reduction efforts? 使用基尼系数、绝对差或百分比变动?存在杠杆效应吗?降低不平等的工作产生了递减效应吗? Given different implicit objectives, poverty or distribution indexes? 不同的隐含目标、贫困或分配指数?
The right side limits 限制和不足 How to “measure” the welfare state [also known as “the dependent variable problem” in political science literature]? 怎样“衡量”福利制度?[在政治学文献资料中也被称为“应变量问题”] Which are welfare policies limits (e.g. have to be included also education, full-employment?) 福利政策的不足有哪些?(如必须包含教育和充分就业) Literature is neither able to define if there has been a retrenchment in last 20 years, depending on how WS is measured (spending, entitlements, outcomes)… 文献资料也未能根据福利体系是怎样衡量的,确定过去20年是否存在紧缩(支出、待遇资格、成果)。。。。。 Two usual measures: 一般采取的两个方法 Social Spending 社会支出 Entitlements 待遇资格
Social spending is not a perfect proxy of a welfare state model… 社会支出不是福利体系模式的一个完美替代值 Spending = f [entitlements (replacement rates, duration..), recipients (elderly, unemployed…), GDP, production costs for services] 支出= f [待遇资格(替代率、发放时间。。。),待遇领取人员(老年人、失业人员。。。),GDP,服务的生产成本] …and different components of social spending may have very different distributive consequences, 。。。并且社会支出的不同内容会产生非常不同的分配效果 …and are included in kind transfers, taxes and tax expenditures? 。。。并且包括实物转移支付、税收和税项支出吗?
2. Entitlements 待遇资格 Entitlements indicators seem more fruitful for defining WS models and analyze their differences and the impact of social policies on recipients. 待遇资格相关指标对确定福利制度的模式并分析其差别,以及分析社会政策对待遇领取人员的影响更为有效。 Recent datasets are useful, but here too there are many limits: 近期的数据库非常有用,但是也存在很多不足: Indicators do not seem robust to different specifications; 各项指标没有不同的具体参数; They are based on few (one or two) illustrative individuals; 各项指标只根据少数(一个或两个)例证个体;
They depend strongly on the reference year. 各项指标主要根据参考年份; They do not incorporate introduced but still transitional changes in norms. 各项指标包括了引入的标准,但尚在过渡中; They are based only on cash transfers!!! What happens to regime theory if services are included? Does education have to be included too? And if yes, which education level? Tax expenditures and the access to private schemes are not considered. 各项指标只基于现金转移支付!!!那么对于包括了服务的制度理论呢?如果也包括教育呢?如果包括,教育水平是什么?没有计算税项支出和获得的私营体系。
Disentangling targeting 对定位的理解 Is targeting really more redistributive and costs saving than universalism? 与普惠性相比,定位性的再分配和成本节约效果确实更大吗? Is there a redistribution paradox? 存在再分配悖论吗? What happens when also private schemes are considered? 如果包括私营制度会怎样? Targeting and universalism have to be compared in connection with the explicit benefit formula. 在比较定位性和普惠性时,需要与精确的待遇计算公式相结合。 Three types of targeting: 定位的三种类型 Categorical 分类型 Means tested 家计调查型 Self targeting 自我定位型
Pros and cons of targeting 定位性的益处和弊端 Pros of targeting 益处 Target efficiency then less poverty and more equality with minor costs 定位的有效性在贫困方面较低,但通过较低成本可以提高公平性。 but the paradox of redistribution could appear: the efficiency of each unit of redistribution vs. how many units are available [is the budget sensible to political constituencies]? 但是会出现再分配悖论:再分配每个单位的有效性vs.可获得多少个单位[预算对政治选区来说是敏感的吗?]
- Leakages (I & II type errors – especially for categorical) The cons of targeting: 弊端 - Leakages (I & II type errors – especially for categorical) 泄漏(第一类和第二类错误---尤其对于分类型) Administrative costs ( especially for means-tested) 行政成本(尤其是对于家计调查型) Incentives (poverty traps) 激励措施(贫困陷阱) Take up and stigma (especially for self targeting and for means tested information failures) 侮辱(尤其对于自我定位和家计调查信息泄露) Towards a citizenship (basic) income? 迈向公民(基本)收入?
