We evaluate the impact of a reduction in the child qualifying age for the One-Parent Family Payment in Ireland. From 2012 to 2015, the child qualifying age was reduced from 18 to 7 years. Lone parents who no longer qualified for the payment, based on the age of their child, could avail of Jobseekers Transitional Payment, which involves a labour activation component. The reforms led to an increase in the average hours worked of lone parents of between 2 and 5 h per week. Lone parents impacted by the policy were 13 percentage points more likely to be working. In addition, we find an increase in household income of between 9% and 12%, and an increase of between 23% and 29% in earnings from employment. Finally, the policy was associated with a 10–14 percentage point reduction in the poverty rate of lone parents.
我们评估了爱尔兰单亲家庭补贴的儿童资格年龄降低的影响。从2012年到2015年,儿童资格年龄从18岁降至7岁。根据子女的年龄不再有资格领取这种津贴的单身父母可以利用求职者过渡津贴,其中包括一项激活劳动力的组成部分。改革导致单身父母每周的平均工作时间增加了2到5小时。受该政策影响的单身父母工作的可能性提高了13个百分点。此外,我们发现家庭收入增加了9%到12%,就业收入增加了23%到29%。最后,该政策还将单身父母的贫困率降低了10-14个百分点。

In developed economies, the population is aging and social security expenditure is projected to increase. This paper examines the effect of increasing the retirement age at which people start receiving pension on human capital investment and labor productivity. I build a quantitative overlapping-generations model with endogenous human capital investment in the Ben-Porath style. I find that increasing the retirement age increases human capital investment and labor productivity. People work for longer years until the new retirement age, and thus they invest more in human capital while young. Increasing the retirement age by 2 years leads to a welfare improvement of 1.2%.
在发达经济体,人口正在老龄化,社会保障支出预计将增加。本文考察了提高退休年龄对人力资本投资和劳动生产率的影响。本文采用本-波拉斯(Ben-Porath)风格,建立了内源性人力资本投资的定量重叠代模型。我发现延长退休年龄增加了人力资本投资和劳动生产率。在新的退休年龄到来之前,人们工作的时间更长,因此他们在年轻时更多地投资于人力资本。将退休年龄延长2年,福利将提高1.2%。

Romanian Abstract: Componenta financiar-bugetară a sistemului național de apărare este foarte importantă. Din această cauză abordăm unele probleme pe baza documentelor / rapoartelor publicate recent. Resursele alocate prin procesul bugetar anual vizează stabilirea capacităților, aducerea sau menținerea acestora la nivelul standardelor, precum și asigurarea funcționalităților de bază ale instituției. Conform recomandărilor NATO, resursele alocate Apărării trebuie completate până când acestea ating nivelul de 2% din PIB. Din abordarea distribuției cheltuielilor de apărare pe categorii, rezultă că cel mai mare procent (66%) aparține cheltuielilor de personal; pentru echipamente se alocă un procent de 14%, iar pentru infrastructură se atribuie cel mai mic procent, 1,5%. Restul de 17% din cheltuielile totale alocate pentru apărare sunt destinate altor activități - întreținere, cercetare și dezvoltare. Auditul activității specifice a arătat că situațiile financiare, în ansamblu, au fost întocmite în conformitate cu cadrul general de raportare financiară și oferă o imagine fidelă a poziției financiare, a performanței financiare a Ministerului Apărării.

Revisiting Retirement and Social Security Claiming Decisions 重新审视退休和社会保障索赔决定
Pub Date : 2021-07-30 DOI: 10.2139/ssrn.3896031
N. Bairoliya, Kathleen McKiernan
Why do individuals retire and claim their Social Security benefits at the age they do? Understanding the key drivers of these decisions has been an important topic of research as it can help guide policy discussions on the impact of potential reforms to the Social Security program. We revisit this crucial question by exploring new sources of heterogeneity in these decisions as well as novel mechanisms governing these trade-offs. Using data from the Health and Retirement Study and the Understanding America Survey, we first document (1) important heterogeneities in social security claiming behavior of men by their education and marital status, (2) strong correlations between health, labor supply and benefit claiming decisions and (3) significant misinformation related to Social Security program knowledge and survival chances at older ages. We then build a life-cycle model of consumption, savings, labor supply, and Social Security application decisions as well as heterogeneity in education, marital status and SS program knowledge. The model includes uncertainty in health, subjective survival, wages, and job separation as well as rich details of the U.S. Social Security program to understand why a majority of individuals claim Social Security benefits prior to their normal retirement age, despite large penalties associated with these early benefit claims. We show that the estimated model can closely match the claiming behavior as seen in the data and also produce differences in SS claims along the dimensions of heterogeneity considered. Counterfactual experiments indicate that precautionary motives, misinformation, and preferences governing future discounting as well as altruism, together, go a long way in explaining overall claiming behavior. Together, these forces can explain a third of the overall early benefit claims and two-thirds of age 62 claims– with varying intensities across education and marital groups.
为什么个人要在他们退休的年龄退休并领取社会保障福利?了解这些决策的关键驱动因素一直是一个重要的研究课题,因为它可以帮助指导有关社会保障计划潜在改革影响的政策讨论。我们通过探索这些决策的异质性的新来源以及管理这些权衡的新机制来重新审视这个关键问题。利用健康与退休研究和了解美国调查的数据,我们首先证明(1)受教育程度和婚姻状况影响的男性社会保障申请行为具有重要的异质性;(2)健康、劳动力供应与福利申请决策之间存在很强的相关性;(3)与社会保障计划知识和老年生存机会相关的显著错误信息。然后,我们建立了消费、储蓄、劳动力供给和社会保障申请决策的生命周期模型,以及教育、婚姻状况和社会保障计划知识的异质性。该模型包括健康、主观生存、工资和离职的不确定性,以及美国社会保障计划的丰富细节,以理解为什么大多数个人在正常退休年龄之前申请社会保障福利,尽管这些早期福利申请会受到巨额罚款。我们表明,估计模型可以与数据中看到的索赔行为密切匹配,并且还会在考虑的异质性维度上产生SS索赔的差异。反事实实验表明,预防动机、错误信息和控制未来贴现的偏好以及利他主义,在解释总体索赔行为方面有很长的路要走。总的来说,这些因素可以解释三分之一的早期福利申请和三分之二的62岁的福利申请——不同教育和婚姻群体的强度不同。

Medicaid Expansion and Medical Liability Costs 医疗补助扩张和医疗责任成本
Pub Date : 2021-07-29 DOI: 10.2139/ssrn.3596507
Jingshu Luo, Hua Chen, Martin Grace
This paper examines the impact of health insurance expansion on medical liability costs using the case of the Affordable Care Act’s (ACA) Medicaid expansion. Medicaid expansion has increased the demand for medical services, but in doing so it may also have increased physicians’ liability in medical practices. By studying medical malpractice insurers’ performance in the U.S. for the period 2010–2018, we find insurers operating in states with Medicaid expansion experienced significantly higher medical liability costs than those in non-expansion states. While insurers in expansion states did increase premiums, the increase was not enough to fully offset rising costs. In addition, we do not find evidence that tort reforms mitigate ACA-induced malpractice liability costs. By exploring the frequency and severity of malpractice claims, we find Medicaid expansion increased malpractice costs mainly by increasing the claim frequency, while tort reforms generally focus on reducing claim severity.
本文以《平价医疗法案》(ACA)的医疗补助扩张为例,考察了医疗保险扩张对医疗责任成本的影响。医疗补助计划的扩大增加了对医疗服务的需求,但这样做也可能增加了医生在医疗实践中的责任。通过研究2010-2018年美国医疗事故保险公司的业绩,我们发现在医疗补助扩张州运营的保险公司的医疗责任成本显著高于未扩张州的保险公司。虽然扩张州的保险公司确实提高了保费,但这一增长不足以完全抵消不断上升的成本。此外,我们没有发现证据表明侵权改革降低了aca引起的医疗事故责任成本。通过探讨医疗事故索赔的频率和严重程度,我们发现医疗补助扩张主要通过增加索赔频率来增加医疗事故成本,而侵权改革通常侧重于降低索赔严重程度。

From Subsidies to Loans: The Effects of a National Student Finance Reform on the Choices of Secondary School Students 从补贴到贷款:国家助学改革对中学生选择的影响

We analyse the effects of a national reform of higher education financing on the decision making of secondary school students in the Netherlands. The reform eliminated a universal subsidy for higher education students and replaced it by a low-interest loan, causing a substantive increase in the private costs of higher education. We show that the reform had a large impact on students’ decision making, decreasing the share of secondary school students following college-preparing tracks by 6.8 percentage points. The reform also affected students’ subject specialization choices, and the living arrangements of new college entrants. We show that secondary school students respond to the costs of higher education well ahead of their graduation, which has important consequences for the design of empirical studies of higher education financing. It also shows that policy uncertainty regarding financial aid is sufficient to deter many students from pursuing higher education.
我们分析了荷兰国家高等教育融资改革对中学生决策的影响。这项改革取消了对高等教育学生的普遍补贴,代之以低息贷款,导致高等教育的私人成本大幅增加。我们发现,这项改革对学生的决策产生了很大的影响,使遵循大学预科课程的中学生比例下降了6.8个百分点。改革还影响了学生的学科专业选择,以及新生的生活安排。我们发现中学生在毕业之前就对高等教育成本做出了反应,这对高等教育融资实证研究的设计具有重要意义。它还表明,经济援助方面的政策不确定性足以阻止许多学生接受高等教育。

The purpose of this study was to investigate the influence of teachers’ characteristics (qualification, years of teaching experience and attitude) and students’ academic performance of Biology in secondary schools in Calabar Municipality of Cross River State, Nigeria. A survey research design was used. And two instruments were used for data collections. Questionnaires and Biology Achievement Test (BAT). Simple random sampling was used to select one hundred and fifty SS2 Biology students and five teachers. Data collected were analyzed using One-way Analysis of Variance (ANOVA). The researcher posited three null hypotheses (two were tested at 0.05 level of significance). The result revealed that teachers’ qualification and teachers’ years of teaching experience inextricably has a significant influence on students’ academic performance in Biology, while teachers’ attitude did not influence students’ academic performance. Based on these findings, the researcher recommended that Government should put in place measure and incentives to encourage and motivate experience teachers in the school system and students should learn to be studious not relying on only for their academic performance.
本研究旨在探讨奈及利亚克罗斯河州卡拉巴尔市中学教师特质(教师资格、教学经验及态度)对学生生物学学业成绩的影响。采用调查研究设计。两种仪器用于数据收集。问卷调查和生物成绩测试(BAT)。采用简单随机抽样的方法,抽取SS2生物系学生150名和教师5名。收集的数据采用单因素方差分析(ANOVA)进行分析。研究人员提出了三个零假设(其中两个在0.05显著性水平上进行了检验)。结果显示,教师的学历和教师的教学年限对学生的生物学学习成绩有着不可分割的显著影响,而教师的态度对学生的生物学学习成绩没有影响。根据这些研究结果,研究人员建议政府应采取措施和奖励措施,鼓励和激励学校系统中有经验的教师,学生应学会勤奋,而不是只依靠学业成绩。

The Value of Delayed Social Security Claiming for Higher-Earning Women 延迟领取社会保障对高收入女性的价值
Pub Date : 2021-05-19 DOI: 10.2139/ssrn.3849653
S. Duffy, Michael S. Finke, David Blanchett
This study estimates the expected benefit from delayed Social Security claiming for higher-earning, healthier women who can expect to receive more future income payments than other Americans. The expected net present value of Social Security payments from delayed claiming for healthy women is $179,999, or more than twice the value of delayed claiming for a male of average health. The benefit from delayed claiming ranges from a low of $16,548 per year to $29,395 per year for healthy women. Even average health women gain at least $132,202 in Social Security wealth by waiting until age 70 to claim Social Security income benefits. Significant gains to women who delay claiming are robust to a 2% increase in real discount rates and to a 21% reduction in income that could occur if the Social Security trust fund depletes in 2026. The added benefits from reduced longevity and inflation risk suggest that the failure to delay claiming results in a significant loss in both retirement wealth and expected welfare.
这项研究估计了高收入、更健康的女性推迟申请社会保障的预期收益,这些女性预计会比其他美国人获得更多的未来收入。健康妇女延迟申领的社会保障金的预期净现值为179 999美元,是健康状况一般的男性延迟申领价值的两倍以上。对健康妇女来说,延迟领取补助金的数额低至每年16 548美元,高至每年29 395美元。即使是普通健康女性,如果等到70岁才申请社会保障收入福利,也能获得至少132,202美元的社会保障财富。推迟申请的女性的显著收益强劲,实际贴现率增加2%,如果社会保障信托基金在2026年耗尽,收入可能会减少21%。寿命缩短和通货膨胀风险降低带来的额外好处表明,未能推迟申领养老金,将导致退休财富和预期福利的重大损失。

The added benefits from reduced longevity and inflation risk suggest that the failure to delay claiming results in a significant loss in both retirement wealth and expected welfare.","PeriodicalId":360236,"journal":{"name":"Political Economy: Government Expenditures & Related Policies eJournal","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131574088","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}

COVID-19 is an ongoing global outbreak of coronavirus disease 2019, an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The World Health Organization (WHO) declared the outbreak a Public Health Emergency of International Concern on January 30, 2020; and a pandemic on March 11, 2020. Several mitigation measures have been used in attempts to limit the spread of the virus, including mandatory wearing of masks in public; bans on unnecessary travel; and the closure of non-essential businesses. This paper defines a lockdown as the closure of non-essential businesses combined with requirements that all citizens stay at home except for grocery shopping, trips to a pharmacy, and medical appointments. The effectiveness of lockdowns is controversial. Proponents tend to argue that lockdowns would have been more effective if enforcement had been increased and if lockdowns had been extended for a longer period of time. Opponents have argued that lockdowns hurt the economy, hurt children, and have had little positive effect on public health. The paper addresses the economic effect of COVID-19 lockdowns in the United States using a Benefit/Cost Analysis (BCA) framework. Two separate analyses are provided: a traditional BCA analysis, which assumes that the value of life is constant regardless of age; and a Preferred Analysis, which adjusts the number of deaths, and values the economic cost of the deaths based on the age of the deceased. Keywords: benefit/cost analysis, COVID-19, GDP, lockdowns, unemployment
2019冠状病毒病是一种由严重急性呼吸系统综合征冠状病毒2 (SARS-CoV-2)引起的传染病,目前正在全球暴发。世界卫生组织(世卫组织)于2020年1月30日宣布此次疫情为国际关注的突发公共卫生事件;以及2020年3月11日的大流行。为了限制病毒的传播,已经采取了一些缓解措施,包括在公共场合强制佩戴口罩;禁止不必要的旅行;以及非必要业务的关闭。这篇文章将封锁定义为关闭非必要的企业,并要求所有公民除了购物、去药店和医疗预约外都呆在家里。封锁的有效性是有争议的。支持者倾向于认为,如果加强执法,如果封锁延长更长的时间,封锁会更有效。反对者认为,封锁会损害经济,伤害儿童,对公共卫生几乎没有积极影响。本文使用效益/成本分析(BCA)框架讨论了COVID-19封锁在美国的经济影响。提供了两种独立的分析:传统的BCA分析,它假设生命的价值与年龄无关;首选分析,调整死亡人数,并根据死者的年龄评估死亡的经济成本。关键词:效益/成本分析,COVID-19, GDP,封锁,失业

The labor supply of older men increased from the 1930s to the 1950s cohort. I estimate a structural model that fits the participation and hours worked by the 1930s cohort well. The observed policy changes in normal retirement age, the earnings test, and delayed retirement credits explain 73.4% and 88.7% of the observed rises in labor force participation and hours worked by the 1950s cohort. Additional policy experiments suggest that postponing retirement age have little effect on older workers, while eliminating the earnings test and reducing retirement benefits would further increase older age participation by 3.37 and 5.10 percent, respectively.
从20世纪30年代到50年代,老年男性的劳动力供给有所增加。我估计有一种结构模型可以很好地适应上世纪30年代那一代人的参与率和工作时间。观察到的正常退休年龄、收入测试和延迟退休信贷的政策变化解释了20世纪50年代人群中观察到的劳动力参与和工作时间增长的73.4%和88.7%。额外的政策实验表明,推迟退休年龄对老年工人影响不大,而取消收入测试和减少退休福利将进一步使老年参与率分别提高3.37%和5.10%。
