This article offers a first approximation of the impacts of the COVID-19 pandemic on the Chilean macro and microeconomic environment, using representative data from the latest formal surveys in the country. Here, the number of active firms plummeted in part due to the social crisis that began on October 18, 2019, and losses were felt in most industries due to the pandemic crisis that continues to generate job losses and low business profitability. These first results have implications for central bank policies and can predict medium and medium-term projections, especially for the country's economic and social growth.
本文利用该国最新正式调查的代表性数据,初步估算了COVID-19大流行对智利宏观和微观经济环境的影响。在这里,活跃企业数量大幅下降,部分原因是2019年10月18日开始的社会危机,由于疫情危机继续导致失业和企业盈利能力低下,大多数行业都出现了亏损。这些初步结果对中央银行的政策有影响,可以预测中期和中期的预测,特别是对国家的经济和社会增长。

Credit Transmission, Liquidity, and Bank Capital in Colombia 哥伦比亚的信贷传导、流动性和银行资本

This document analyses monetary policy effects on transmission of credit interest rates in Colombia with particular attention to the period of global liquidity spurred by the COVID-pandemic during 2020-2022. Challenges for banks operating in Colombia are twofold: they face increasing banking competition (reinforced by FINTECH) and increasing credit risks due to deteriorating macro-financial conditions after a -6.8% real-GDP and an average of 16% in unemployment over 2020. Expected rebound for 2021 looks mild at 4% in real-GDP and staggered unemployment averaging 14%.Credit transmission has been fairly rapid in corporate credits, but slow in consumption loans, given contract prevalence at fix-rates (87% of total) and extensions averaging 6 years in the latter. Gains in credit transmission would require: i) deepening of the swaps market of interest rates, currently focused at OTC instead of the registered market;and ii) increasing the floating portion related to the IBR (bid-market over the central bank repo-window), currently covering only 12% of the portfolio. This would be the Colombian version of the worldwide move from LIBOR into SFAR. However, this deepening of capital markets in Colombia hinge crucially in preserving the “investment grade” status over 2021-2022, currently facing unanimous “negative outlook” from the rating agencies. Finally, compression of financial wedges, increasing credit risks, and higher liquidity-capital requirements (over 2021-2024, under Basle III) represent significant challenges for banks operating in Colombia. Financial Superintendence recently reported Colombia as complying with Basle III, after the transition period of 2016-2019, joining the 42% of LATAM countries in that category.
本文件分析了货币政策对哥伦比亚信贷利率传导的影响,特别关注2020-2022年期间covid - 19大流行引发的全球流动性时期。在哥伦比亚经营的银行面临着双重挑战:他们面临着日益激烈的银行业竞争(由金融科技加强),以及由于宏观金融状况恶化而增加的信贷风险,因为2020年实际gdp为-6.8%,平均失业率为16%。2021年的预期反弹看起来温和,实际gdp增长4%,交错失业率平均为14%。企业信贷的信贷传导相当迅速,但消费贷款的信贷传导速度较慢,因为合同普遍采用固定利率(占总量的87%),而消费贷款的平均展期为6年。信贷传导的收益将需要:i)深化利率掉期市场,目前主要集中在场外交易而不是注册市场;ii)增加与IBR相关的浮动部分(中央银行回购窗口的投标市场),目前仅占投资组合的12%。这将是哥伦比亚版的世界范围内从LIBOR到SFAR的转变。然而,哥伦比亚资本市场的深化对于在2021-2022年期间保持“投资级”地位至关重要,目前评级机构一致将其评为“负面展望”。最后,金融楔子的压缩、信贷风险的增加和更高的流动性资本要求(根据巴塞尔协议III, 2021-2024年)对在哥伦比亚经营的银行构成了重大挑战。金融监管局最近报告称,哥伦比亚在2016-2019年过渡期后遵守了巴塞尔协议III,加入了42%的拉丁美洲国家的行列。

In this report, the Committee on Capital Markets Regulation (the “Committee”) describes the turmoil in the U.S. Treasury market during March 2020, with a focus on the unexpected rise in Treasury yields, the illiquidity in the Treasury market and the subsequent intervention by the Federal Reserve to stabilize the market. We then describe the market structure for trading U.S. Treasuries as well as trade reporting requirements and public information regarding the owners of Treasuries. We find that policymakers and the public lack the transaction data to comprehensively determine the source of selling in March 2020 that drove the volatility in the U.S. Treasury market.Policymakers have sought to identify the source of the selling pressure in the Treasury market in March 2020 because holders of U.S. Treasuries, including large financial institutions and foreign investors, rely on the assumption that Treasuries are cash-like instruments.1 For U.S. Treasuries to continue to function as a global safe haven asset, Treasuries must retain their value and trade efficiently during market crises. Identifying the source of the selling pressure in March 2020 would enable policymakers to determine whether changes to regulation or market structure are necessary to allow the Treasury market to better accommodate such selling in the future. In-deed, understanding the potential sources of fragility in the Treasury market remains important, as periodic bouts of volatility persist—most recently in February 2021.2In Part I of our report, we summarize the volatility in the U.S. Treasury market in March 2020 and the Federal Reserve’s role in stabilizing the market. In Part II, we provide a comprehensive overview of the market structure for trading U.S. Treasuries (so-called “cash Treasury” markets), including the respective role of broker-dealers, proprietary trading firms, institutional inves-tors and trading venues. Part II then describes the trade information for U.S. Treasuries available to regulators from the Financial Industry Regulatory Authority’s Trade Reporting and Compliance Engine (“FINRA’s TRACE database”). Finally, in Part III we evaluate public disclosures of ownership information and trade data for U.S. Treasuries, including data provided by the Federal Reserve and U.S. Treasury Department regarding institutional investors, foreign investors and foreign official investors (such as central banks and sovereign wealth funds). We also review public disclosures regarding the U.S. Treasury holdings of hedge funds and mutual funds.We conclude that policymakers and the public lack the trade and ownership information necessary to comprehensively determine the source of selling in the Treasury market in March 2020.

在本报告中,资本市场监管委员会(“委员会”)描述了2020年3月美国国债市场的动荡,重点关注国债收益率的意外上升、国债市场的流动性不足以及美联储随后为稳定市场而进行的干预。然后,我们描述了交易美国国债的市场结构,以及交易报告要求和有关国债所有者的公开信息。我们发现,政策制定者和公众缺乏交易数据,无法全面确定2020年3月推动美国国债市场波动的抛售来源。政策制定者一直试图确定2020年3月美国国债市场抛售压力的来源,因为包括大型金融机构和外国投资者在内的美国国债持有者依赖于美国国债是类似现金的工具的假设美国公债若要继续扮演全球避险资产的角色,就必须保持其价值,并在市场危机期间有效交易。在2020年3月确定抛售压力的来源,将使政策制定者能够确定是否有必要改变监管或市场结构,以使国债市场更好地适应未来的这种抛售。事实上,了解美国国债市场脆弱性的潜在来源仍然很重要,因为周期性波动持续存在——最近一次是在2021年2月。在我们报告的第一部分中,我们总结了2020年3月美国国债市场的波动以及美联储在稳定市场方面的作用。在第二部分中,我们全面概述了交易美国国债的市场结构(所谓的“现金国债”市场),包括经纪自营商、自营交易公司、机构投资者和交易场所各自的角色。然后,第二部分描述了监管机构可以从金融业监管局的贸易报告和合规引擎(“FINRA的TRACE数据库”)获得的美国国债贸易信息。最后,在第三部分中,我们评估了美国国债所有权信息和交易数据的公开披露,包括美联储和美国财政部提供的关于机构投资者、外国投资者和外国官方投资者(如中央银行和主权财富基金)的数据。我们还审查了有关对冲基金和共同基金持有美国国债的公开披露。我们得出的结论是,政策制定者和公众缺乏全面确定2020年3月美国国债市场抛售来源所需的贸易和所有权信息。因此,我们建议政策制定者在得出结论或制定与2020年3月美国国债收益率飙升相关的法规之前要谨慎行事。对政策制定者来说,适当的第一步是考虑是否有必要扩大美国国债市场参与者的报告义务。此外,政策制定者应继续研究美国国债市场的活动,以确定其他改革是否可以提高其效率、弹性和透明度。

Sue The Fed: The Case for Privately Enforceable Statutory Constraints on Federal Reserve Emergency Lending 起诉美联储:对美联储紧急贷款进行私人强制执行的法定限制的案例
Pub Date : 2021-03-05 DOI: 10.2139/SSRN.3798534

The federal government’s economic response to the COVID-19 epidemic has principally been one in which the Federal Reserve has set up extraordinary lending facilities in partnership with the Treasury Department. These facilities were modeled on multi-trillion-dollar lending facilities set up by the Federal Reserve in 2008 in response to the prior economic crisis. These Federal Reserve lending facilities are extraordinary in size but also extraordinary because they involve lending to firms that are not banks. Federal Reserve lending over the first hundred years of its history was almost exclusively limited to banks. Congress put in place statutory limits on this extraordinary lending authority in the Dodd-Frank Act of 2010 to limit the Federal Reserve’s discretion and minimize the risk that generous lending by the Federal Reserve would encourage excessive risk taking. Those limits prohibit the Fed from supporting insolvent firms, from propping up individual firms like it did with AIG in 2008, includes a number of other prescriptive measures to ensure the Federal Reserve takes reasonable risk management practices even in extraordinary times. This paper argues that those limits have not proven enforceable nor constraining on the Fed’s discretion, and this paper instead argues that a private right of action to enforce them would better fulfill Congress’ objective in the Dodd-Frank Act to limit Federal Reserve discretion in lending to non-banks.
联邦政府对COVID-19疫情的经济反应主要是美联储与财政部合作建立了特别贷款机制。这些工具是仿造美联储在2008年为应对之前的经济危机而设立的数万亿美元贷款工具。这些美联储贷款工具的规模非同一般,但也非同一般,因为它们涉及向银行以外的公司提供贷款。在美联储历史的头一百年里,它的贷款几乎完全局限于银行。国会在2010年的《多德-弗兰克法案》(Dodd-Frank Act)中对这一特殊的贷款权力进行了法定限制,以限制美联储的自由裁量权,并将美联储慷慨放贷鼓励过度冒险的风险降至最低。这些限制禁止美联储支持资不抵债的公司,也禁止美联储像2008年对美国国际集团(AIG)那样支持个别公司,还包括一些其他规定措施,以确保美联储即使在非常时期也能采取合理的风险管理措施。本文认为,这些限制并没有被证明是可执行的,也没有限制美联储的自由裁量权,相反,本文认为,一个私人的行动权来执行这些限制,将更好地实现国会在多德-弗兰克法案中的目标,即限制美联储向非银行机构贷款的自由裁量权。

What Drives Closed-End Fund Discounts? Evidence from COVID-19 是什么推动了封闭式基金的折扣?来自COVID-19的证据

Exploiting the exogenous COVID-19 shock, this paper attempts to shed light on the closed-end fund (CEF) discount puzzle. CEF discounts increased substantially after COVID-19, and I identify a causal role of sentiment in this effect. I show that COVID-19 reduced individual investor sentiment. Using the difference-in-differences (DiD) approach, I find that CEFs with higher sentiment beta or higher retail ownership experienced a larger increase in discounts after the COVID-19 shock. The DiD results are unlikely to be driven by alternative channels such as the liquidity, expense, payout, and leverage channels. Overall, the results support the sentiment-based explanation of CEF discounts.
本文试图利用外生的COVID-19冲击,揭示封闭式基金(CEF)贴现之谜。在COVID-19之后,CEF折扣大幅增加,我认为情绪在这种影响中起着因果作用。我指出,COVID-19降低了个人投资者的情绪。使用差分法(DiD),我发现情绪贝塔值较高或零售拥有率较高的CEFs在COVID-19冲击后折扣幅度较大。DiD结果不太可能由其他渠道驱动,如流动性、费用、支出和杠杆渠道。总体而言,结果支持基于情绪的CEF折扣解释。

Understanding how the Papua New Guinea (PNG) agricultural economy and associated household consumption is affected by climate, market and other shocks requires attention to linkages and substitution effects across various products and the markets in which they are traded. In this study, we use a multi-market simulation model of the PNG food economy that explicitly includes production, consumption, external trade and prices of key agricultural commodities to quantify the likely impacts of a set of potential shocks on household welfare and food security in PNG.

In this study, we use a multi-market simulation model of the PNG food economy that explicitly includes production, consumption, external trade and prices of key agricultural commodities to quantify the likely impacts of a set of potential shocks on household welfare and food security in PNG. We have built the model to be flexible in order to explore different potential scenarios and then identify where and how households are most affected by an unexpected shock. The model is designed using region and country-level data sources that inform the structure of the PNG food economy, allowing for a data-driven evaluation of potential impacts on agricultural production, food prices, and food consumption. Thus, as PNG confronts different unexpected challenges within its agricultural economy, the model presented in this paper can be adapted to evaluate the potential impact and necessary response by geographic region of an unexpected economic shock on the food economy of the country.

We present ten simulations modeling the effects of various shocks on PNG’s economy. The first group of scenarios consider the effects of shocks to production of specific agricultural commodities including: 1) a decrease on maize and sorghum output due to Fall Armyworm; 2) reduction in pig production due to a potential outbreak of African Swine Fever; 3) decline in sweet potato production similar to the 2015/16 El Niño Southern Oscillation (ENSO) climate shock; and 4) a decline in poultry production due to COVID-19 restrictions on domestic mobility and trade. A synopsis of this report, which focuses on the COVID-19 related shocks on the PNG economy is also available online (Diao et al., 2020).

The second group of simulations focus on COVID-19-related changes in international prices, increased marketing costs in international and domestic trade, and reductions in urban incomes. We simulate a 1) 30 percent increase in the price of imported rice, 2) a 30 percent decrease in world prices for major PNG agricultural exports, 3) higher trade transaction costs due to restrictions on the movement of people (traders) and goods given social distancing measures of COVID-19, and 4) potential economic recession causing urban household income to fall by 10 percent. Finally, the last simulation considers the combined effect of all COVID-19 related shocks combining the above scenarios into a single simulation.

了解巴布亚新几内亚农业经济和相关家庭消费如何受到气候、市场和其他冲击的影响,需要关注各种产品及其交易市场之间的联系和替代效应。在本研究中,我们使用巴布亚新几内亚粮食经济的多市场模拟模型,明确包括主要农产品的生产、消费、对外贸易和价格,以量化一系列潜在冲击对巴布亚新几内亚家庭福利和粮食安全的可能影响。在本研究中,我们使用巴布亚新几内亚粮食经济的多市场模拟模型,明确包括主要农产品的生产、消费、对外贸易和价格,以量化一系列潜在冲击对巴布亚新几内亚家庭福利和粮食安全的可能影响。我们建立了灵活的模型,以便探索不同的潜在情况,然后确定家庭在哪里以及如何受到意外冲击的最大影响。该模型利用区域和国家一级的数据源设计,这些数据源提供了巴布亚新几内亚粮食经济结构的信息,允许对农业生产、粮食价格和粮食消费的潜在影响进行数据驱动的评估。因此,由于巴布亚新几内亚在其农业经济中面临不同的意外挑战,本文提出的模型可以适用于评估意外经济冲击对该国粮食经济的潜在影响和按地理区域作出的必要反应。我们提出了十个模拟模拟各种冲击对巴布亚新几内亚经济的影响。第一组情景考虑了冲击对特定农产品生产的影响,包括:1)秋粘虫导致玉米和高粱产量下降;2)由于可能爆发非洲猪瘟导致生猪产量减少;3)甘薯产量下降与2015/16年厄尔Niño南方涛动(ENSO)气候冲击相似;4)由于COVID-19对国内流动和贸易的限制,家禽产量下降。该报告的摘要也可在网上获得(Diao et al., 2020),重点关注与COVID-19相关的冲击对巴布亚新几内亚经济的影响。第二组模拟侧重于与covid -19相关的国际价格变化、国际和国内贸易营销成本增加以及城市收入减少。我们模拟了以下情况:1)进口大米价格上涨30%,2)巴布亚新几内亚主要农产品出口的世界价格下跌30%,3)由于COVID-19的社会距离措施,人员(贸易商)和货物流动受到限制,贸易交易成本上升,以及4)潜在的经济衰退导致城市家庭收入下降10%。最后,最后一个模拟考虑了所有与COVID-19相关的冲击的综合影响,将上述情景合并为一个模拟。分析的一个关键结果是,城市家庭,特别是城市贫困人口,特别容易受到与COVID-19大流行相关的冲击。城市地区经济活动减少(假定会使城市非农业收入减少10%),国内贸易中断导致营销成本增加,进口大米价格上涨30%,这些因素加在一起,使城市贫困和非贫困家庭的收入减少了近15%。然而,城市贫困家庭的卡路里消费量下降幅度最大,为19.8%,而城市非贫困家庭的卡路里消费量下降幅度为15.8%。在这些模拟中,农村家庭受COVID-19相关冲击的影响要小得多。农村家庭收入主要受到城市需求减少和市场混乱的影响,仅下降了约4%。然而,农村贫困人口和非贫困人口的卡路里消费量分别下降了5.5%和4.2%。

We have built the model to be flexible in order to explore different potential scenarios and then identify where and how households are most affected by an unexpected shock. The model is designed using region and country-level data sources that inform the structure of the PNG food economy, allowing for a data-driven evaluation of potential impacts on agricultural production, food prices, and food consumption. Thus, as PNG confronts different unexpected challenges within its agricultural economy, the model presented in this paper can be adapted to evaluate the potential impact and necessary response by geographic region of an unexpected economic shock on the food economy of the country. <br><br>We present ten simulations modeling the effects of various shocks on PNG’s economy. The first group of scenarios consider the effects of shocks to production of specific agricultural commodities including: 1) a decrease on maize and sorghum output due to Fall Armyworm; 2) reduction in pig production due to a potential outbreak of African Swine Fever; 3) decline in sweet potato production similar to the 2015/16 El Niño Southern Oscillation (ENSO) climate shock; and 4) a decline in poultry production due to COVID-19 restrictions on domestic mobility and trade.

Child-Proofing Global Public Health in Anticipation of Emergency 紧急情况下的儿童保护全球公共卫生
Pub Date : 2021-02-12 DOI: 10.2139/SSRN.3789677
Frederick M. Abbott
The response of the international community to the COVID-19 pandemic has been characterized by a lack of transparency, substantial gaps in scientific understanding, inconsistent communication, lack of capacity for the manufacture of vaccines, substantial gaps in preparedness for diagnostics and personal protective equipment, absence to date of an effective treatment, and political conflict. What makes most of these problems the more glaring is that we understood the gaps well in advance, but we were not prepared to address them. Regrettably for the international community, the pandemic struck during a confluence of political trends that culminated in strong nationalist and anti-science political movements. Can International law provide a more resilient framework in which the decisions of national leaders during crisis are less likely to cause harm? A framework in which we are less susceptible to ad hoc and incoherent decision making? In a way we are asking whether international law can child-proof the working space of global public health, making it less susceptible to the transient ebb and flow of national political leaders? A fully functioning global public health system would prepare us in advance to address viral and other pathogenic outbreaks in terms of robust R&D platforms and sound manufacturing infrastructure. It would alert us to an outbreak at the earliest possible date, and it would instruct us regarding the appropriate interim protective measures to take, all without triggering perceptions of personal insecurity that lead to social unrest and conflict. While flagging some of the potential obstacles it is nevertheless worth considering the possibility for a comprehensive International arrangement to prepare for and address future pandemic outbreaks. Given the many interests implicated by pandemic outbreaks – which COVID-19 reminds us can have extensive and devastating impacts around the world – it might be well to envisage a self-standing regime, or a regime negotiated under the auspices of the United Nations. This would take into account the “political equality” of the principal multilateral institutions. An international convention or other mechanism to address a pandemic must create winners. It cannot be perceived as depriving Party A to satisfy the needs of Party B.
国际社会对COVID-19大流行的反应具有以下特点:缺乏透明度,科学理解存在重大差距,沟通不一致,疫苗生产能力不足,诊断和个人防护装备准备方面存在重大差距,迄今为止缺乏有效治疗,以及政治冲突。使大多数这些问题更加突出的是,我们事先很好地了解了这些差距,但我们没有准备好解决它们。令国际社会感到遗憾的是,疫情发生时正值各种政治趋势汇合,最终导致强烈的民族主义和反科学政治运动。国际法能否提供一个更有弹性的框架,使国家领导人在危机期间的决定不太可能造成伤害?一个我们不太容易受到临时和不连贯决策影响的框架?在某种程度上,我们在问,国际法是否能够保护全球公共卫生的工作空间,使其不那么容易受到国家政治领导人昙花一现的潮起潮落的影响?一个功能齐全的全球公共卫生系统将使我们在强大的研发平台和健全的制造基础设施方面提前为应对病毒和其他致病性疫情做好准备。它将提醒我们尽早爆发疫情,并指导我们采取适当的临时保护措施,所有这些都不会引发导致社会动荡和冲突的个人不安全感。尽管指出了一些潜在的障碍,但值得考虑是否有可能作出一项全面的国际安排,以防备和应对未来大流行病的爆发。鉴于大流行疫情所涉及的许多利益——COVID-19提醒我们,疫情可能在世界各地产生广泛和破坏性的影响——我们不妨设想一个独立的制度,或者在联合国主持下通过谈判建立一个制度。这将考虑到主要多边机构的“政治平等”。应对大流行病的国际公约或其他机制必须创造赢家。不能为了满足乙方的需要而剥夺甲方的权利。

Стратегии уcтойчивой мобильноcти: лучшие мировые практики (Strategies for Sustainable Urban Mobility: Analysis of Best Practices ) Стратегиитуcойчивоймобильноcти:лучшиемировыепрактики(可持续城市流动:战略分析的最佳实践)
Pub Date : 2021-02-10 DOI: 10.18288/1994-5124-2021-1-82-103

The article is dedicated to the analysis of the approved strategies for sustainable mobility (sustainable transport) in the world’s leading cities. It is shown that most strategic documents contain similar principles and goals that determine the transformation vectors for cities. The fundamental principles include hierarchy of priorities (not only financial, but also in terms of equitable distribution of urban space, starting from pedestrian and bicycle mobility and public transport and ending with parking); increasing ecomobility, involving the “80:20” principle (fixing the goal of bringing the share of sustainable modes of mobility to 80% and decreasing the share of cars to 20% by 2030); “healthy streets, healthy people” and “complete streets” (reformatting car-oriented streets into bicycle and pedestrian spaces, administrative restrictions for cars, internalization of externalities); development of environmentally friendly high-speed rail public transport and the creation of preferential access rights for public transport; Vision Zero (zero tolerance for road accidents); compactness, polycentricity, and transit-oriented development; smart transport and multimodality; consideration of the transport system as one of the integral parts of the city’s stability (holistic view), etc. It is determined that the analyzed mobility strategies organically integrate into the general trajectory of sustainable long-term development and promotion of real human wellbeing. Most strategies focus on personal experience of their beneficiaries, which lies at the heart of any reform (people-centered approach). An additional benefit resulting from the implementation of sustainable mobility strategies is lower density and safer distancing within cities, which is highly relevant in the context of the COVID-19 pandemic, as well as reduced freight prices and development of a more just and secure city environment.
本文致力于分析世界领先城市的可持续交通(可持续交通)批准战略。研究表明,大多数战略文件都包含类似的原则和目标,这些原则和目标决定了城市的转型向量。基本原则包括优先级(不仅在财政上,而且在城市空间的公平分配方面,从行人、自行车和公共交通开始,到停车结束);增加生态交通,涉及“80:20”原则(确定到2030年将可持续交通方式的份额提高到80%,将汽车的份额降低到20%的目标);“健康的街道,健康的人”和“完整的街道”(将汽车导向的街道重新格式化为自行车和步行空间,对汽车进行行政限制,外部性内部化);发展环境友好型高速铁路公共交通,设立公共交通优惠准入权;零愿景(对道路交通事故零容忍);紧凑、多中心和以交通为导向的发展;智能交通和多式联运;考虑将交通系统作为城市稳定性的一个组成部分(整体观点)等。结果表明,所分析的流动性战略有机地融入了可持续长期发展和促进人类真正福祉的总体轨迹。大多数战略注重受益者的个人经验,这是任何改革的核心(以人为本的方法)。实施可持续交通战略的另一个好处是,在2019冠状病毒病大流行的背景下,城市内的人口密度降低,距离更安全,货运价格降低,城市环境更加公正和安全。

Unemployment in the Time of Covid-19: A Flow-Based Approach to Real-Time Unemployment Projections 2019冠状病毒病时期的失业:基于流量的实时失业预测方法
Pub Date : 2021-02-01 DOI: 10.3386/W28445
A. Sahin, Murat Tasci, Jin Yan
This paper presents a flow-based methodology for real-time unemployment rate projections and shows that this approach performed considerably better at the onset of the COVID-19 recession in the spring 2020 in predicting the peak unemployment rate as well as its rapid decline over the year. It presents an alternative scenario analysis for 2021 based on this methodology and argues that the unemployment rate is likely to decline to 5.4 percent by the end of 2021. The predictive power of the methodology comes from its combined use of real-time data with the flow approach.
本文提出了一种基于流量的实时失业率预测方法,并表明该方法在2020年春季COVID-19衰退开始时,在预测失业率峰值及其在一年内的快速下降方面表现得更好。它提出了基于这种方法的2021年的另一种情景分析,并认为失业率可能会在2021年底降至5.4%。该方法的预测能力来自于实时数据与流方法的结合使用。

Biases in Information Selection and Processing: Survey Evidence from the Pandemic 信息选择和处理中的偏见:来自大流行的调查证据
Pub Date : 2021-02-01 DOI: 10.2139/ssrn.3783215

We conduct two survey experiments to study which information people choose to consume and how it affects their beliefs. In the first experiment, respondents choose between optimistic and pessimistic article headlines related to the COVID-19 pandemic, and are then randomly shown one of the articles. Respondents with more pessimistic prior beliefs tend to prefer pessimistic headlines, providing evidence of confirmation bias. Additionally, respondents assigned to the less preferred article discount its information. The second experiment studies the role of partisan views, uncovering strong source dependence: news source revelation further distorts information acquisition, eliminating the role of priors in article choice.
我们进行了两个调查实验来研究人们选择消费哪些信息以及这些信息如何影响他们的信念。在第一个实验中,受访者在与COVID-19大流行相关的乐观和悲观文章标题中进行选择,然后随机显示其中一篇文章。具有更悲观先验信念的受访者倾向于选择悲观的标题,这为确认偏误提供了证据。此外,被分配到不太受欢迎的文章的受访者对其信息进行了折扣。第二个实验研究了党派观点的作用,揭示了强烈的来源依赖:新闻来源披露进一步扭曲了信息获取,消除了先验在文章选择中的作用。
