If school closures and social-distancing experiences during the Covid-19 pandemic impeded children’s skill development, they may leave a lasting legacy in human capital. Our parental survey during the second German school lockdown provides new measures of socio-emotional development and panel evidence on how students’ time use and educational inputs adapted over time. Children’s learning time decreased severely during the first school closures, particularly for low-achieving students, and increased only slightly one year later. In a value-added model, learning time increases with daily online class instruction, but not with other school activities. Parental assessments of children’s socio-emotional development are mixed. Discussing our findings in light of the emerging literature on substantial achievement losses, we conclude that unless remediated, the school closures will persistently increase inequality and reduce skill development, lifetime income, and economic growth.
如果在2019冠状病毒病大流行期间学校关闭和保持社交距离的经历阻碍了儿童的技能发展,它们可能会在人力资本方面留下持久的遗产。我们在德国第二次学校封锁期间的家长调查提供了社会情感发展的新措施,并提供了关于学生时间利用和教育投入如何随时间变化的小组证据。在第一次学校关闭期间,儿童的学习时间严重减少,特别是成绩差的学生,一年后仅略有增加。在增值模式中,学习时间随着日常在线课堂教学而增加,而不是随着其他学校活动而增加。父母对孩子社会情感发展的评估是混杂的。根据新兴的关于重大成就损失的文献讨论我们的研究结果,我们得出结论,除非加以补救,否则学校关闭将持续加剧不平等,降低技能发展、终身收入和经济增长。

The Gender Effects of COVID-19 on Equity Analysts COVID-19对股票分析师的性别影响
Pub Date : 2021-10-26 DOI: 10.2139/ssrn.3857376

We use the COVID-19 pandemic as a natural experiment to study the effects of childcare and household duties on sell-side analysts. The richness of this setting allows us to compare female and male analysts while requiring them to perform the same tasks. We find that female analysts' forecast accuracy declined more than male analysts, especially when schools were closed and among analysts who were more likely to have young children, inexperienced, were likely busier before the pandemic, and lived in southern states. Female analysts also reduced the timeliness of their forecasts and resorted to more heuristic forecasts. The stock market was aware of this and became less responsive to female analysts' forecasts. However, female analysts did not reduce their coverage or updating frequency relative to male analysts. We also find the above widening gender gap was temporary and became statistically insignificant by May/June 2020. Overall, our results show that the pandemic impacted female analysts more than males through the quality of their forecasts but not the quantity.
我们使用COVID-19大流行作为自然实验来研究儿童保育和家庭责任对卖方分析师的影响。这种设置的丰富性使我们能够在要求女性和男性分析师执行相同任务的同时,对他们进行比较。我们发现,女性分析师的预测准确性下降幅度大于男性分析师,尤其是在学校关闭、更有可能有年幼孩子、经验不足、可能在大流行前更忙、居住在南部各州的分析师中。女性分析师还降低了预测的及时性,更多地采用启发式预测。股市意识到了这一点,对女性分析师的预测反应减弱。然而,相对于男性分析师,女性分析师并没有减少他们的覆盖范围或更新频率。我们还发现,上述不断扩大的性别差距是暂时的,到2020年5月/ 6月,性别差距在统计上不显著。总的来说,我们的结果表明,大流行对女性分析师的影响比男性分析师更大,主要是通过预测的质量,而不是数量。

Impacts of the COVID Lockdown on Consumption: Household Data from India COVID封锁对消费的影响:来自印度的家庭数据
Pub Date : 2021-10-04 DOI: 10.2139/ssrn.3840563

In this paper, we quantify impacts on consumption expenditure and patterns following India’s initial sudden lockdown in response to the COVID-19 pandemic, and the gradual relaxation that followed. We use household survey data from a representative Indian state, Punjab. We separate the effects on rural versus urban households, and by whether households were female-headed, or had daily laborers. While the urban population cut back expenditure across all categories, rural households shifted toward basic commodities and cut back more on other expenditure. Rural households that included daily-wage laborers were the most severely affected.
在本文中,我们量化了印度为应对COVID-19大流行而开始的突然封锁以及随后的逐步放松对消费支出和模式的影响。我们使用了印度旁遮普邦的家庭调查数据。我们区分了对农村和城市家庭的影响,以及家庭是否由女性担任户主,或者是否有日工。在城市人口削减所有类别支出的同时,农村家庭转向基本商品,并更多地削减其他支出。包括日薪劳动者在内的农村家庭受影响最严重。

Status Externalities in Education and Low Birth Rates in Korea 韩国教育的地位外部性与低出生率
Pub Date : 2021-10-01 DOI: 10.2139/ssrn.3866660
Seongeun Kim, M. Tertilt, Minchul Yum
South Korea has been experiencing a very low total fertility rate around 1.2 over the last two decades. A serious concern of the Korean government about low fertility is demonstrated by its billions-dollars worth spending in recent years. In this paper, we aim to understand why the birth rate is so low in Korea and to assess whether there is a reason for the government to be concerned. We ask what, if anything, could and should be done about the low fertility rate. To do so, we propose status externalities as a new reason for inefficiently low fertility. In our model with endogenous fertility, parents care about the education of their children relative to other parent’s children. We find that the equilibrium is characterized by over-investment in education and under-investment in fertility, relative to the first best. We calibrate the model to Korean data to quantify the role of the status externality. We find that without it fertility would be 17% higher. We also find the externality plays a large role in explaining the fertility-income relationship, which is positive in Korea, in contrast to most other countries. We conduct several policy experiment and find that taxing education would not be desirable in welfare terms, even though it reduces the over-investment. Similarly, pronatal transfers do increase the fertility rate but are also not welfare improving. We conclude that more subtle policies are needed to rectify the friction introduced through status concerns.
在过去的20年里,韩国的总生育率一直很低,约为1.2。近年来,韩国政府投入了数十亿美元的资金,证明了政府对低生育率的严重担忧。在本文中,我们的目的是了解为什么韩国的出生率如此之低,并评估是否有理由让政府感到担忧。我们要问,对于低生育率,如果有的话,可以而且应该做些什么。为此,我们提出了身份外部性作为低生育率无效的新原因。在我们的内生生育模型中,相对于其他父母的孩子,父母更关心自己孩子的教育。我们发现,相对于第一优,均衡的特点是教育投资过度,生育投资不足。我们将模型校准为韩国数据,以量化地位外部性的作用。我们发现,如果没有它,生育率会高出17%。我们还发现,外部性在解释生育率-收入关系方面发挥了很大作用,与大多数其他国家相比,韩国的外部性是正的。我们进行了几项政策实验,发现对教育征税在福利方面是不可取的,即使它减少了过度投资。同样,产前转移确实提高了生育率,但也没有改善福利。我们的结论是,需要更微妙的政策来纠正由于地位问题而引起的摩擦。

Did Precious Metals Serve as Hedge and Safe-Haven Alternatives to Equity during the COVID-19 Pandemic: New Insights Using a Copula-Based Approach 在COVID-19大流行期间,贵金属是否可以作为股票的对冲和避险替代品:使用基于copula的方法的新见解
Pub Date : 2021-10-01 DOI: 10.2139/ssrn.3934171

We examine the hedging and safe-haven characteristics between four major precious metals (gold, silver, platinum, and palladium) and three major US stock market indices. The metal markets are known for hedging and safety characteristics during financial distress. The paper sheds new insights into the hedging and safe-haven ability of the precious metals under extreme stock market volatility conditions caused by the COVID-19 by drawing empirical estimates using two different copula approaches. The results show that gold outperforms all other precious metals such as silver, platinum, and palladium in hedging abilities under extreme stock market conditions. Likewise, gold remains a safe-haven asset both in calm and turbulent periods, and silver possibly remains the next best alternative, albeit as a weak safe-haven asset.
我们研究了四种主要贵金属(黄金、白银、铂和钯)和三大美国股市指数之间的对冲和避险特征。在金融危机期间,金属市场以对冲和安全特性而闻名。本文通过使用两种不同的copula方法进行实证估计,对COVID-19导致的极端股市波动条件下贵金属的对冲和避险能力进行了新的见解。结果表明,在极端的股票市场条件下,黄金在对冲能力方面优于所有其他贵金属,如银、铂和钯。同样,无论是在平静时期还是动荡时期,黄金仍是一种避险资产,而白银可能仍是次佳选择,尽管其避险能力较弱。

(Post-)pandemic Employment Dynamics in a Comparative Perspective 从比较的角度看大流行后的就业动态
Pub Date : 2021-09-27 DOI: 10.2139/ssrn.3931219
Stefan Jestl, Robert Stehrer
Policy recommendations Fiscal and monetary policies should remain expansionary to ensure that the nascent labour market recovery continues, allowing a quick recovery to pre-crisis employment levels. Fiscal policy should focus on pressing short-term needs, but also on supporting the EU’s transition to tackle challenges of the future, including the climate crisis and digitalisation. Policymakers need to take into account the pandemic’s divergent employment effects across industries. Employment-support schemes must be kept in place for those industries that are still suffering, and must be quickly re-activated for other areas of the economy in the case of renewed lockdowns in the autumn. This is crucial in order to minimise as much as possible the permanent labour market scarring that the pandemic will cause. Policymakers need to put particular emphasis on younger and low-skilled workers, as well as those in heavily affected industries and regions. If the pandemic has caused a permanent, structural shift in the nature of work and demand for particular skills, active labour market policies must be enacted to support the transition. Workers lacking digital skills or those living in areas with a high reliance on tourism are likely to be particularly exposed. It is of vital importance that the social security system, rather than workers themselves, bears the brunt of this transition. Long-term unemployment must be minimised as much as possible. The longer workers spend without a job, the harder it will be to reintegrate them back into the labour market.
政策建议财政和货币政策应保持扩张性,以确保新生的劳动力市场持续复苏,使就业迅速恢复到危机前的水平。财政政策应侧重于紧迫的短期需求,但也应支持欧盟向应对未来挑战的过渡,包括气候危机和数字化。政策制定者需要考虑到疫情对各行业就业的不同影响。必须为那些仍然受到影响的行业保留就业支持计划,并且必须在秋季再次封锁的情况下迅速为其他经济领域重新启动就业支持计划。这是至关重要的,以便尽可能减少大流行将对劳动力市场造成的永久性创伤。政策制定者需要特别重视年轻和低技能工人,以及受影响严重的行业和地区的工人。如果大流行病造成了工作性质和对特定技能需求的永久性结构性转变,就必须制定积极的劳动力市场政策,支持这种转变。缺乏数字技能的工人或生活在高度依赖旅游业地区的工人可能特别容易受到影响。至关重要的是,在这种转变中首当其冲的是社会保障体系,而不是工人本身。必须尽可能地减少长期失业。工人失业的时间越长,就越难让他们重新融入劳动力市场。

A countrywide lockdown instituted via prime Minister Narendra Modi at the early levels of the worldwide pandemic was meant to alleviate the stresses on Indian’s insufficient healthcare system, however it also brought a 24 percentage contraction in the economy and led millions of migrant day workers to flee India’s towns for lack of work. thru the late fall and wintry weather, it seemed that by some means India might break out the worst of the pandemic, but that hope has now been dashed by a devastating combination of new viral strains and inadequate public health preparations.

世界越来越清楚印度第二波冠状病毒激增的严重程度,美国政策制定者很快开始理解印度国家创伤的战略影响。总统和他的高级官员公开承诺将向印度运送医疗用品,包括氧气、疫苗材料和治疗药物,同时寻找应对印度危机的其他方法。在过去的12个月里,COVID-19已经对印度经济造成了毁灭性的打击。总理纳伦德拉·莫迪(Narendra Modi)在全球大流行的早期阶段实施了全国范围的封锁,旨在缓解印度不足的医疗体系所带来的压力,但这也导致印度经济萎缩24%,并导致数百万移民日工因缺乏工作而逃离印度城镇。在深秋和寒冷的天气中,印度似乎可能以某种方式爆发最严重的大流行,但这种希望现在已经被新的病毒株和公共卫生准备不足的破坏性组合所破灭。印度现在面临着这一波病毒的耗尽和耗尽。中印关系,又称中印关系或印中关系,是指中华人民共和国和印度共和国之间的双边关系。尽管两国关系友好,但也存在边界争端。目前的关系始于1950年,而印度成为最早结束与中华民国(台湾)正式关系的国家之一,并了解人类的中华民国,因为中国大陆的有效政府。中国和印度是亚洲两个主要的地区大国,也是全球人口最多和增长最快的两个主要经济体。外交和金融影响力的激增增加了两国双边交往的重要性。

Agree to Disagree? Predictions of U.S. Nonfarm Payroll Changes between 2008 and 2020 and the Impact of the COVID19 Labor Shock 同意或不同意?对2008年至2020年美国非农就业人数变化的预测以及covid - 19劳动力冲击的影响

We analyze an unbalanced panel monthly predictions of nonfarm payroll (NFP) changes between January 2008 and December 2020 sourced from Bloomberg. Unsurprisingly, we find that prediction quality varies across economists and we reject the hypothesis of equal predictive ability. In an error decomposition, we find evidence of significantly biased forecasts. Participation rate in the survey is affecting this bias. We find that survey participants under-predict job losses in times of market turmoil while also under-predicting the recovery thereafter, especially during the COVID19 labor shock. For prediction of NFP changes, autoregressive models are outperformed by a deep learning long short-term memory network. However, the consensus forecast yields better forecasts than model-based approaches and are further improved by combining the forecasts of the best performing economists. The COVID19 labor shock is shown to have adverse effects on the prediction performance of economists. However, not all economists are affected equally.
我们分析了2008年1月至2020年12月间来自彭博社的非农就业人数(NFP)月度预测。不出所料,我们发现经济学家的预测质量各不相同,我们拒绝预测能力相等的假设。在误差分解中,我们发现预测存在显著偏差的证据。调查的参与率影响了这种偏见。我们发现,调查参与者低估了市场动荡时期的失业人数,同时也低估了市场动荡之后的复苏,尤其是在2019冠状病毒病劳动力冲击期间。对于NFP变化的预测,深度学习长短期记忆网络优于自回归模型。然而,共识预测比基于模型的方法产生更好的预测,并通过结合表现最好的经济学家的预测进一步改进。新冠肺炎疫情对经济学家的预测效果产生了不利影响。然而,并非所有经济学家都受到同样的影响。

The COVID19 labor shock is shown to have adverse effects on the prediction performance of economists. However, not all economists are affected equally.","PeriodicalId":20373,"journal":{"name":"Political Economy - Development: Health eJournal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81710864","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}

This paper proposes risk measures for bank solvency by accurately measuring the solvency risk components. These measures consider the minimum regulatory solvency levels and banks’ risk appetite level and risk profile. For this purpose, we used semi-nonparametric statistics to model stylized facts of the risk distribution, particularly the high-order moments of the Solvency Decline Rate, the Tier Decline Rate, and the Portfolio Growth Rate variables. Additionally, these risk measures can be used to measure the risk of regulatory intervention and to define policies that establish the minimum solvency levels required by banking regulators by estimating the Quantile Risk Metrics. As a case study, we collected data on the solvency indicators of the Colombian banking system, which adapts to the standards established by the Basel Committee. According to the results, the liquidity injection measures implemented in response to the needs generated by the COVID-19 pandemic led to an increase in the levels of the risk portfolio in the Colombian banking system, which exceeded the 99th percentile of the probability distribution of monthly portfolio value changes.
本文通过对偿付能力风险成分的准确度量,提出了银行偿付能力的风险度量方法。这些措施考虑了最低监管偿付能力水平和银行的风险偏好水平和风险概况。为此,我们使用半非参数统计对风险分布的风格化事实进行建模,特别是偿付能力下降率、分层下降率和投资组合增长率变量的高阶矩。此外,这些风险度量可用于度量监管干预的风险,并通过估计分位风险度量来定义建立银行监管机构要求的最低偿付能力水平的政策。作为案例研究,我们收集了哥伦比亚银行体系偿付能力指标的数据,该体系符合巴塞尔委员会制定的标准。结果显示,为应对COVID-19大流行产生的需求而实施的流动性注入措施导致哥伦比亚银行体系风险投资组合水平上升,超过了月度投资组合价值变化概率分布的第99个百分位数。

The State-of-the-Art of NPLs in the Post COVID World: An Ongoing Concern for the Future 新冠肺炎后世界的不良贷款状况:对未来的持续关注
Pub Date : 2021-09-16 DOI: 10.2139/ssrn.3931491

The purpose of this article is to examine the current situation of non-performing loans (NPLs) in the EU from a diachronic perspective, with a special focus on the regulatory and factual events relating to the Covid-19 pandemic. Although we agree with Cicero that "Historia vero testis temporum, lux veritatis, vita memoriae, magistra vitae, nuntia vetustatis", our reflections on the status of NPLs in Europe are necessarily more nuanced. History can serve as a powerful guide, but the greatest disruptive scenarios require a conscious and consistent adjustment by people and regulations. Specifically, they must seek to cope with unforeseen developments that differ from those faced in the past, requiring continued awareness and flexibility. To this end, it is necessary to proceed step by step and begin with a thorough review of the rationale and goals of NPL-related measures taken so far. First of all, it is necessary to examine and recall the critical role played by banks in the economy and how they are able to absorb losses up to a certain amount. It is equally important to note that they cannot cope with heavy losses, which often occur in situations where their ability to lend credit and their reputation on the market cannot shield them from the impact of both pathological NPL flows and the inadequacy of their NPL management structures. Meanwhile, it should also be recalled that the cause of the most recent NPL crisis was linked to the sub-prime crisis, which taught us that the hardest risk to foresee is the probability of default even by normally well-paying debtors. The current situation faced by EU Member States is filled with yet more uncertainty, but we are far better prepared now than we were then. The post-Covid era will benefit from the many safeguards which have already been implemented, including: the prohibition of profit distribution by banks recommended by the EBA; greater flexibility in the interpretation of financial statement criteria (IFRS) and the classification of NPLs; and some essential measures to streamline the functioning of the secondary market for selling or restructuring NPLs. Against this background, empirical evidence can show us which direction we are moving in. It shows that we should not to drop our guard, but rather keep a watchful eye on the situation and act promptly and swiftly if/when needed. More precisely, following the NPL regulatory framework developed by the EU and several nations in the mid-2010s, NPL ratios and the aggregate amount of NPLs consistently dropped between 2015 and the first quarter of 2021, with the one exception being the first quarter of 2021 which saw a slight uptick in the aggregate number of NPLs. Moreover, corporate and household debt levels across some of the more traditionally problematic financial markets in the EU remain relatively healthy, at least compared to 2013 levels. However, government debt-to-GDP levels have increased substantially (almost doubled) in 2020 compared to the mi
本文旨在从历时的角度审视欧盟不良贷款(NPLs)的现状,并特别关注与Covid-19大流行相关的监管和事实事件。虽然我们同意西塞罗的“历史上对时间的检验、真理、生命的记忆、地方的生命、不确定性的生命”,但我们对欧洲不良贷款状况的反思必然更加微妙。历史可以提供有力的指导,但最具破坏性的情景需要人们和监管机构有意识地进行持续的调整。具体地说,它们必须设法应付不同于过去所面临的不可预见的事态发展,这需要持续的认识和灵活性。为此目的,有必要一步一步地进行,并首先彻底审查迄今所采取的与国家化学物质有关的措施的理由和目标。首先,有必要审视和回顾银行在经济中所扮演的关键角色,以及它们如何能够吸收一定数量的损失。同样重要的是要注意,他们无法应对严重的损失,这往往发生在他们的贷款能力和他们在市场上的声誉无法保护他们免受病态不良贷款流动和不良贷款管理结构不足的影响的情况下。与此同时,我们也应该记住,最近的不良贷款危机的起因与次贷危机有关,次贷危机告诉我们,最难预测的风险是违约的可能性,即使是通常支付良好的债务人。欧盟成员国面临的当前形势充满了更多的不确定性,但我们现在比那时准备得更好。后covid时代将受益于已经实施的许多保障措施,包括:EBA建议禁止银行的利润分配;在解释财务报表准则(IFRS)和不良贷款分类方面具有更大的灵活性;以及一些必要措施,以简化二级市场出售或重组不良贷款的功能。在这种背景下,经验证据可以告诉我们正在朝哪个方向前进。这表明我们不应该放松警惕,而应该保持警惕,并在需要时迅速采取行动。更准确地说,根据欧盟和几个国家在2010年代中期制定的不良贷款监管框架,不良贷款率和不良贷款总额在2015年至2021年第一季度之间持续下降,唯一的例外是2021年第一季度,不良贷款总额略有上升。此外,在欧盟一些传统上问题较多的金融市场,企业和家庭债务水平仍然相对健康,至少与2013年的水平相比是如此。然而,与2000年代中期相比,2020年政府债务占gdp的比例大幅增加(几乎翻了一番),并达到了会员国有史以来的最高水平。这可能限制会员国在发生金融或经济危机时进行干预的能力。我们这样说并不是为了引起警觉,而是作为一种警告,让人们保持高度警惕,并对这个话题保持兴趣。它绝不是过时的,绝不是可以用历史本身提供的有用但相当简陋的工具来解决的。
