Subsidies induce a market inefficiency by creating a deadweight loss since supply and demand are out of equilibrium. In 2016, electricity subsidies were the largest component of the total global energy subsides, with an estimated 128 billion USD out of 287 billion USD. Electricity generation is also directly responsible for a quarter of global greenhouse gas emissions. Under baseline assumptions about supply and demand elasticities and employing the latest available data, we first estimate the welfare loss of global electricity subsidies and then estimate the global environmental costs imposed by electricity consumption. We find that the total annual deadweight loss worldwide in 2016 was 12.4 billion USD. Incorporating external costs stemming from excessive consumption, which is a result of prices that are less than the private marginal cost, leads to a total annual welfare loss of 43.2 billion USD. This number accounts for 4.5% of the total electricity market value in electricity-subsidizing countries. Furthermore, we estimate that the worldwide electricity consumption imposes environmental costs of at least 652.8 billion USD annually; thus, the total annual costs in the global electricity markets are nearly 700 billion USD.
由于供给和需求不平衡,补贴造成了无谓损失,从而导致市场效率低下。2016年,电力补贴是全球能源补贴总额的最大组成部分,约为2870亿美元中的1280亿美元。发电还直接造成了全球四分之一的温室气体排放。在关于供需弹性的基线假设下,利用最新的可用数据,我们首先估算了全球电力补贴的福利损失,然后估算了电力消费带来的全球环境成本。我们发现,2016年全球年度载重损失总额为124亿美元。如果加上过度消费所产生的外部成本,即价格低于个人边际成本,那么每年的福利损失总额为432亿美元。这一数字占电力补贴国家总电力市场价值的4.5%。此外,我们估计全球电力消耗每年造成的环境成本至少为6528亿美元;因此,全球电力市场每年的总成本接近7000亿美元。

This paper exploits panel data from the Food Security Survey to examine varying transaction costs on SNAP benefit take-up by tracking individuals eligible for SNAP benefits. Using a logistic regression model, I find SNAP-eligible households living in states with relatively low transaction costs are more likely to take up SNAP benefits than similar households in high transaction cost states.
本文利用来自粮食安全调查的面板数据,通过跟踪有资格获得SNAP福利的个人,来检查SNAP福利接受的不同交易成本。使用逻辑回归模型,我发现生活在交易成本相对较低的州的SNAP合格家庭比高交易成本州的类似家庭更有可能接受SNAP福利。

Fiscal Federalism and the Budget Impacts of the Affordable Care Act's Medicaid Expansion 财政联邦制和《平价医疗法案》医疗补助扩张的预算影响
Pub Date : 2020-03-01 DOI: 10.3386/w26862

Medicaid’s federal-state matching system of financing is the nation’s largest example of fiscal federalism. Using generous federal subsidies, the Affordable Care Act incentivized states to expand Medicaid, which became a state option in the aftermath of a 2012 Supreme Court ruling. As of early 2020, 14 states had not yet expanded, with concerns over state budgetary effects described as a key barrier. We use an event-study approach to analyze state budget data from 2010-2018 and assess the effects of state Medicaid expansion decisions. We find that Medicaid expansion increased total spending in expansion states by 6% to 9%, compared to non-expansion states. By source of funds, federal spending via the states increased by 10% in the first year of Medicaid expansion, rising to 27% in 2018. Changes in spending from state funding were modest and non-significant, with less than a 1% change from baseline annually in the most recent years, 2017 and 2018. Meanwhile, we find no evidence that increased Medicaid spending from expansion produced any reductions in spending on education, corrections, transportation, or public assistance. Changes in Medicaid spending tracked closely with the baseline pre-ACA (2013) uninsured rate in each states, with expansion leading to roughly $2680 in added annual spending per uninsured adult. As a result, we estimate states that didn’t expand Medicaid passed up $43 billion in federally-subsidized program funds in 2018. Finally, state projections in the aggregate were reasonably accurate, with expansion states projecting average Medicaid spending from 2014-2018 within 2 percent of the actual amounts, and in fact overestimating Medicaid spending in most years.
医疗补助的联邦-州配对融资体系是美国财政联邦制的最大范例。利用慷慨的联邦补贴,《平价医疗法案》(Affordable Care Act)激励各州扩大医疗补助计划(Medicaid)。在2012年最高法院(Supreme Court)的一项裁决之后,医疗补助成为了各州的选择。截至2020年初,有14个州尚未扩张,对州预算影响的担忧被认为是一个关键障碍。我们使用事件研究方法来分析2010-2018年的州预算数据,并评估州医疗补助扩张决策的影响。我们发现,与没有扩大医疗补助计划的州相比,扩大医疗补助计划的州的总支出增加了6%到9%。从资金来源来看,在医疗补助扩张的第一年,各州的联邦支出增长了10%,2018年上升到27%。国家资金支出的变化不大,也不显著,在最近几年、2017年和2018年,每年从基线变化不到1%。与此同时,我们没有发现任何证据表明,扩大医疗补助计划的支出增加会导致教育、矫正、交通或公共援助方面的支出减少。医疗补助支出的变化与aca实施前(2013年)各州未参保率的基线密切相关,扩张导致每个未参保成年人的年支出增加约2680美元。因此,我们估计,没有扩大医疗补助计划的州在2018年浪费了430亿美元的联邦补贴项目资金。最后,各州的总体预测相当准确,扩张州对2014-2018年平均医疗补助支出的预测在实际金额的2%以内,实际上在大多数年份都高估了医疗补助支出。

Inequality and Spending Policy 不平等与支出政策
Pub Date : 2020-02-15 DOI: 10.2139/ssrn.3538799
D. Hasen
Reformers often argue that the welfare benefits of ameliorating inequality are worth the cost in reduced economic efficiency that supposedly results from associated increases in government spending. This paper argues that these arguments are mostly misguided. Focusing solely on the marginal benefit of government- versus private-sector spending, there is ample reason to conclude that many governmental expenditures directed to reducing inequality are justifiable on the basis that they improve overall efficiency, even as they also reduce inequality. Because the efficiency argument directly addresses the concerns that otherwise animate restraint in redistributive programs, treating the reduction of inequality as a tradeoff against efficiency losses that is otherwise worthwhile is mostly counterproductive from a social policy perspective. Reformers instead should engage proponents of economic efficiency on their own terms.

In making this argument, the paper also develops the concept of “budget policy endogeneity,” or the idea that the affordability or not of various programs must take into account the allocative and distributional effects of current spending on future wealth, since revenue for current projects may be raised in the future. If current spending enhances allocative efficiency, programs that can only be funded with borrowing today create the conditions for their relatively less burdensome repayment tomorrow.
改革者经常认为,改善不平等所带来的福利收益,与政府支出相应增加所导致的经济效率下降所付出的代价是值得的。本文认为,这些观点大多是被误导的。只关注政府支出与私营部门支出的边际效益,有充分的理由得出结论,许多旨在减少不平等的政府支出是合理的,因为它们提高了整体效率,即使它们也减少了不平等。因为关于效率的争论直接解决了对再分配计划的约束的担忧,所以从社会政策的角度来看,把减少不平等看作是对效率损失的权衡,而效率损失本来是值得的。相反,改革者应该以他们自己的方式与经济效率的支持者接触。在提出这一论点时,本文还提出了“预算政策内生性”的概念,即各种计划的可承受性或不可承受性必须考虑当前支出对未来财富的分配和分配效应,因为当前项目的收入可能在未来增加。如果当前支出提高了配置效率,那么今天只能通过借款来提供资金的项目,将为未来偿还负担相对较轻的项目创造条件。

Solidarity through Redistribution and Insurance of Incomes: The EU As Support, Guide, Guarantor or Provider? 通过收入再分配和保险实现团结:欧盟是支持、指导、担保人还是提供者?
Pub Date : 2020-02-03 DOI: 10.2139/ssrn.3530876
Frank Vandenbroucke
Income redistribution and insurance are core functions of welfare states. What role should the EU play in this domain? I examine the purchase of normative theorizing on social justice on this question, building on the contrast between three models of EU involvement: the EU as Support, which implies the sharing of resources through intergovernmental transfers; the EU as Provider, which implies EU cross-border transfers towards individual citizens; the EU as Guide or Guarantor, which implies that the EU formulates normative policy ideals. I review different normative accounts of justice for the EU (Ronzoni, Viehoff, Sangiovanni, Van Parijs), and how they bear on the choice between these models of EU involvement in welfare state solidarity. These accounts evolve between two extreme positions. On the one hand, an account based on supranational justice as ‘background justice for nation states’ implies that the EU should be a mere instrument in the hands of its member states. The opposite extreme position is that EU should be a laboratory for international distributive justice, whereby national welfare states are demoted to the toolbox of instruments. I argue that an account of justice for the EU must search for a middle ground, whereby neither the national welfare states nor the EU are demoted to mere instruments. I conclude that the EU should support the member states’ welfare states in some of their key functions, on the basis of common social standards and in pursuit of upward convergence. Such a ‘Social Union’ would be a Support, Guide and Guarantor, both in the realm of insurance and redistribution. Through the establishment of interstate insurance, it would be a true ‘insurance union’, but, from the point of view of individual citizens, it would not become a direct Provider of insurance. It would engage in interstate redistribution, but not in interpersonal cross-border redistribution.
收入再分配和保险是福利国家的核心功能。欧盟在这一领域应该扮演什么角色?在欧盟参与的三种模式的对比基础上,我考察了关于这个问题的社会正义的规范性理论的购买:欧盟作为支持,这意味着通过政府间转移共享资源;欧盟作为提供者,这意味着欧盟向公民个人进行跨境转移;欧盟作为指南或担保人,这意味着欧盟制定规范性的政策理想。我回顾了欧盟正义的不同规范解释(Ronzoni, Viehoff, Sangiovanni, Van Parijs),以及它们如何影响欧盟参与福利国家团结的这些模式之间的选择。这些说法在两种极端立场之间演变。一方面,基于超国家正义作为“民族国家的背景正义”的解释意味着欧盟应该仅仅是其成员国手中的工具。相反的极端立场是,欧盟应该成为国际分配正义的实验室,国家福利国家应该被降格为工具工具箱。我认为,对欧盟正义的解释必须寻找一个中间立场,在这个中间立场上,国家福利国家和欧盟都不会被贬为纯粹的工具。我的结论是,欧盟应该在共同社会标准和追求向上趋同的基础上,支持成员国福利国家的一些关键职能。这样一个“社会联盟”将在保险和再分配领域起到支持、指导和保证的作用。通过建立州际保险,它将成为一个真正的“保险联盟”,但从公民个人的角度来看,它不会成为一个直接的保险提供者。它会参与州际再分配,但不会参与人际间的跨境再分配。

David N. Figlio, Cassandra M. D. Hart, Krzysztof Karbownik
Using a rich dataset that merges student-level school records with birth records, and a student fixed effect design, we explore how the massive scale-up of a Florida private school choice program affected public school students’ outcomes. Expansion of the program produced modestly larger benefits for students attending public schools that had a larger initial degree of private school options, measured prior to the introduction of the voucher program. These benefits include higher standardized test scores and lower absenteeism and suspension rates. Effects are particularly pronounced for lower-income students, but results are positive for more affluent students as well.
我们使用丰富的数据集,将学生级别的学校记录与出生记录合并在一起,并使用学生固定效应设计,探讨了佛罗里达州私立学校选择计划的大规模扩大如何影响公立学校学生的成绩。在引入代金券计划之前,对就读公立学校的学生来说,该计划的扩大为他们带来了略大的好处,这些学生最初有更多的私立学校选择。这些好处包括更高的标准化考试成绩,更低的缺勤率和停学率。对低收入家庭的学生影响尤其明显,但对较富裕的学生也有积极的影响。

Does a General Theory of Welfare Institutions Explain the Expansion of Social Assistance in Low and Middle Income Countries? 福利制度的一般理论能解释中低收入国家社会救助的扩张吗?

What theory can help us to explain the expansion of social assistance in low and middle income countries? Prevailing theories of welfare institutions, including power resources and varieties of capitalism, were developed to study the welfare institutions that emerged among early industrialisers. The paper revisits these theories with a view to identifying elements of general applicability to the study of emerging social assistance in late industrialisers. Two hypotheses on the growth of social assistance are tested using panel data for 2000-2015 and a within-between mixed estimation model. The results suggest a general theory of welfare institutions is capable of throwing light on emergent welfare institutions in low and middle income countries, while highlighting important gaps.
什么理论可以帮助我们解释中低收入国家社会救助的扩大?福利制度的主流理论,包括权力资源和各种资本主义,都是为了研究早期工业化国家中出现的福利制度而发展起来的。本文重新审视了这些理论,以期确定对后期工业化国家新兴社会援助研究普遍适用的要素。本文使用2000-2015年的面板数据和介于两者之间的混合估计模型对社会救助增长的两个假设进行了检验。结果表明,福利制度的一般理论能够揭示低收入和中等收入国家的新兴福利制度,同时突出了重要的差距。

Does HUD Overpay for Voucher Units, and Will SAFMRs Reduce the Overpayment? 住房和城市发展部是否为代金券单位支付了过高的费用?
Pub Date : 2019-07-10 DOI: 10.2139/ssrn.3427803

Small Area Fair Market Rents is an important reform of HUD's Housing Choice Voucher Program. One argument for them is that they would reduce overpayment for voucher units in low-rent neighborhoods. This leads to the belief that the benefits of SAFMRs can be funded largely by reductions in landlord profits rather than by losses to voucher recipients who remain in low-rent areas. The usual theoretical argument that has led many to believe that voucher units are overpriced focuses on one implication of one feature of the Housing Choice Voucher program. This article provides a more comprehensive theoretical analysis that leads to the conclusion that the worst voucher units and those in the worst neighborhoods will usually rent for more than the mean market rent of identical units, and the best units in the best neighborhoods will rent for less than this amount. The debate over this matter has ignored the bulk of the available evidence. This article summarizes and assesses the data, methods, and results of the major studies. The evidence is consistent with the general pattern predicted by the comprehensive theoretical analysis but also with an alternative explanation that challenges its interpretation as overpayments and underpayments for voucher units. The mix of units with estimated overpayments and underpayments varies across studies, but the weight of the evidence is that the aggregate differences are modest. Finally, the evidence available indicates that SAFMRs will decrease the rents paid for voucher units with any specified set of characteristics in the worst neighborhoods and will increase the rents of such units in the best neighborhoods.
小面积公平市场租金是住房和城市发展部住房选择券计划的一项重要改革。支持他们的一个理由是,他们将减少在低租金社区为代金券单位支付的超额费用。这导致人们相信,safmr的好处主要可以通过房东利润的减少来提供,而不是通过留在低租金地区的代金券接受者的损失来提供。导致许多人相信代金券单位定价过高的通常理论论点集中在住房选择代金券计划的一个特征的一个含义上。本文提供了一个更全面的理论分析,得出的结论是,最差的代金券单位和最差的社区通常租金高于相同单位的平均市场租金,而最好的社区的最好的单位租金低于这个数额。关于这个问题的争论忽略了大部分可获得的证据。本文对主要研究的数据、方法和结果进行了总结和评价。证据与综合理论分析预测的一般模式一致,但也与另一种解释相一致,这种解释挑战了对代金券单位的多付和少付的解释。在不同的研究中,估计多付和少付的单位组合有所不同,但证据的权重是,总体差异不大。最后,现有证据表明,在最差的社区中,SAFMRs会降低具有任何特定特征的代金券单元的租金,而在最好的社区中,这类单元的租金会增加。

This article provides a more comprehensive theoretical analysis that leads to the conclusion that the worst voucher units and those in the worst neighborhoods will usually rent for more than the mean market rent of identical units, and the best units in the best neighborhoods will rent for less than this amount. The debate over this matter has ignored the bulk of the available evidence. This article summarizes and assesses the data, methods, and results of the major studies. The evidence is consistent with the general pattern predicted by the comprehensive theoretical analysis but also with an alternative explanation that challenges its interpretation as overpayments and underpayments for voucher units. The mix of units with estimated overpayments and underpayments varies across studies, but the weight of the evidence is that the aggregate differences are modest. Finally, the evidence available indicates that SAFMRs will decrease the rents paid for voucher units with any specified set of characteristics in the worst neighborhoods and will increase the rents of such units in the best neighborhoods.","PeriodicalId":196905,"journal":{"name":"ERN: Government Expenditures & Welfare Programs (Topic)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134355515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Intergenerational Transmission of Welfare Dependency 福利依赖的代际传递
Pub Date : 2018-07-09 DOI: 10.2139/ssrn.3237303

There is a strong intergenerational correlation in welfare participation, but this does not imply that parental welfare receipt induces child receipt. While there are a few quasi-experimental studies that provide estimates of the causal effect of parental welfare participation for children from marginal welfare participants, we know very little about intergenerational spillovers of welfare participation onto the children of average welfare participants. By combining rich administrative data from Norway with weak mean-monotonicity assumptions, we estimate nonparametric bounds around the average causal effect of parental welfare participation on children’s welfare participation in the general population, as well as the average causal effect for children growing up in welfare-dependent families. We find that these average causal effects are considerably lower than the intergenerational correlation in welfare participation, and substantially below available local average treatment effect estimates in the literatu . We further find important differences between intergenerational spillovers of disability insurance and intergenerational spillovers of financial assistance, a traditional means-tested welfare program.
在福利参与方面有很强的代际相关性,但这并不意味着父母的福利接受会导致孩子的福利接受。虽然有一些准实验研究提供了父母福利参与对边缘福利参与者的孩子的因果影响的估计,但我们对福利参与对平均福利参与者的孩子的代际溢出效应知之甚少。通过将挪威丰富的行政数据与弱平均单调性假设相结合,我们估计了父母福利参与对儿童在一般人群中的福利参与的平均因果效应的非参数界限,以及在福利依赖家庭中长大的儿童的平均因果效应。我们发现这些平均因果效应远低于福利参与的代际相关性,并且大大低于文献中现有的当地平均治疗效应估计。我们进一步发现,残疾保险的代际溢出效应与经济援助(一项传统的经济状况调查福利计划)的代际溢出效应存在重要差异。

The Effects of Universal Public Childcare Provision on Cases of Child Neglect and Abuse 普遍公共托儿服务对儿童忽视和虐待案件的影响
Pub Date : 2018-07-01 DOI: 10.2139/ssrn.3234210

We investigate the impact of childcare provision on cases of child abuse and neglect in Germany between 2002 and 2014. For identification, we exploit a governmental reform introducing mandatory early child care. The implementation at the county level generated large temporal and spatial variation in childcare coverage. Our measure of child abuse and neglect comes from a unique high-quality administrative data set that covers all child protection cases at the German county level. The estimated ITT effect shows a decline by 0.24 cases per 1,000 children if a county increases childcare slots above the median, which is a reduction of 21.4 percent from the mean. This finding is of high economic relevance given the enormous costs of child abuse and neglect for the society. Our results show that the provision of universal public child care can be an effective policy to prevent part of these costs.
我们调查了2002年至2014年间德国儿童保育对儿童虐待和忽视案件的影响。为了证明这一点,我们利用了一项引入强制性幼儿保育的政府改革。在县一级的实施造成了儿童保育覆盖面的巨大时空差异。我们对儿童虐待和忽视的衡量标准来自一个独特的高质量的行政数据集,该数据集涵盖了德国县级的所有儿童保护案件。估计的ITT效应显示,如果一个县在中位数以上增加托儿名额,每1000名儿童中就会减少0.24例,比平均值减少21.4%。鉴于虐待和忽视儿童给社会带来的巨大代价,这一发现具有很高的经济意义。我们的研究结果表明,提供普遍的公共儿童保育可以是一项有效的政策,以防止这些成本的一部分。
