In this work we introduce a general equilibrium model with landlords, indebted owner-occupiers and renters to study housing markets' dynamics. We estimate it by using standard Bayesian methods and match the US data of the last decades. This framework is particularly suited to explain current trends on housing markets. We highlight the crucial relationship between interest rates, house prices and rents, and argue that it helps understanding the main driving forces. Our analysis suggests that current developments on housing markets can play a role for a recovery from the Covid pandemic as they have an expansionary effect on aggregate output. Moreover, we account for the heterogeneous impact of crisis-induced policies depending on agents' status on the housing market. We show how, despite an increase in housing prices, the welfare of landlords has been negatively hit. This is associated to the joint decrease in returns on housing and financial assets that reduces their financial incomes.
在这项工作中,我们引入了一个一般均衡模型,包括房东、负债自住业主和租房者,以研究住房市场的动态。我们使用标准贝叶斯方法进行估计,并与美国近几十年的数据进行匹配。这个框架特别适合解释当前房地产市场的趋势。我们强调了利率、房价和租金之间的关键关系,并认为这有助于理解主要驱动因素。我们的分析表明,目前房地产市场的发展可以为从Covid大流行中复苏发挥作用,因为它们对总产出具有扩张性影响。此外,我们考虑了危机引发的政策的异质影响,这取决于代理人在房地产市场上的地位。我们展示了尽管房价上涨,房东的福利如何受到负面打击。这与住房和金融资产回报率的共同下降有关,这减少了他们的金融收入。

Coronavirus Ethics: Judgments of Market Ethics in a Pandemic 冠状病毒伦理:大流行中的市场伦理判断
Pub Date : 2020-12-17 DOI: 10.2139/ssrn.3750616

COVID-19 has required major changes in behavior and created significant health and economic concerns for many individuals. In this context, we have explored ethical judgments as part of a larger project on market ethics. We found that marketing practices judged as highly unethical before the pandemic, were judged to be much less unethical one year later. Of the questionable practices examined during the lockdown, those related to the pandemic (e.g., price gouging on hand sanitizer) were generally evaluated the most unethical, equal to or more unethical than the most egregious practices previously tested. Experience of lockdown affected ethical judgments, with number of people in the household, lockdown duration, and time spent on social media associated with less unethical judgments. Broader effects of the pandemic, including negative affect, diminished well-being, and financial difficulties, were also associated with less ethical concern. Implications for policymakers and marketing practitioners are discussed.
COVID-19要求人们在行为上做出重大改变,并给许多人带来了重大的健康和经济问题。在这种背景下,我们将道德判断作为一个更大的市场伦理项目的一部分进行了探讨。我们发现,在大流行之前被认为非常不道德的营销做法,在一年后被认为不道德程度要低得多。在封锁期间审查的可疑做法中,与大流行有关的做法(例如,哄骗洗手液的价格)通常被评为最不道德的做法,相当于或比以前测试的最恶劣的做法更不道德。封锁经历影响了道德判断,其中家庭人数、封锁持续时间和在社交媒体上花费的时间与较少的不道德判断相关。大流行的更广泛影响,包括负面影响、幸福感下降和经济困难,也与较少的道德关切有关。对政策制定者和营销从业者的影响进行了讨论。

Liquidity Management During the COVID-19 Pandemic COVID-19大流行期间的流动性管理
Pub Date : 2020-12-15 DOI: 10.2139/ssrn.3759618
Heitor Almeida
With the help of the US government and committed funding from bank credit lines, the US corporate sector responded to the COVID-19 cash flow shock by issuing long-term debt to increase cash holdings. I use a case study, evidence from recent research and a theoretical model to explain the logic behind the changes in corporate financial policy that happened during 2020, and to discuss the importance of US government policies to support the market for long-term debt. I also point out to open research questions about liquidity management, in particular questions that were highlighted by how companies reacted to the COVID-19 pandemic.
在美国政府的帮助下,在银行信贷额度的承诺下,美国企业通过发行长期债券来增加现金持有量,以应对新冠肺炎现金流冲击。我用一个案例研究、近期研究的证据和一个理论模型来解释2020年企业财务政策变化背后的逻辑,并讨论美国政府政策对支持长期债务市场的重要性。我还指出了关于流动性管理的开放式研究问题,特别是企业如何应对COVID-19大流行所突出的问题。

Efficient Social Distancing for COVID-19: An Integration of Economic Health and Public Health 有效保持社会距离应对COVID-19:经济卫生与公共卫生的结合
Pub Date : 2020-12-04 DOI: 10.2139/ssrn.3742507

Social distancing has been the only effective way to contain the spread of an infectious disease prior to the availability of the pharmaceutical treatment. It can lower the infection rate of the disease at the economic cost. A pandemic crisis like COVID-19, however, has posed a dilemma to the policymakers since a long-term restrictive social distancing or even lockdown will keep economic cost rising. This paper investigates an efficient social distancing policy to manage the integrated risk from economic health and public health issues for COVID-19 using a stochastic epidemic modeling with mobility controls. The social distancing is to restrict the community mobility, which was recently accessible with big data analytics. This paper takes advantage of the community mobility data to model the COVID-19 processes and infer the COVID-19 driven economic values from major market index price, which allow us to formulate the search of the efficient social distancing policy as a stochastic control problem. We propose to solve the problem with a deep-learning approach. By applying our framework to the US data, we empirically examine the efficiency of the US social distancing policy and offer recommendations generated from the algorithm.
在获得药物治疗之前,保持社交距离一直是遏制传染病传播的唯一有效方法。它可以以经济成本降低疾病的感染率。然而,像COVID-19这样的大流行危机给政策制定者带来了两难境地,因为长期的限制性社交距离甚至封锁将使经济成本不断上升。本文利用具有流动性控制的随机流行病模型,研究了一种有效的社会距离政策,以管理COVID-19的经济健康和公共卫生问题的综合风险。保持社交距离是为了限制最近通过大数据分析得到的社区流动性。本文利用社区流动数据对新冠肺炎疫情过程进行建模,并从主要市场指数价格中推断出新冠肺炎疫情驱动的经济价值,从而将有效社会距离政策的寻找作为一个随机控制问题。我们建议用深度学习的方法来解决这个问题。通过将我们的框架应用于美国的数据,我们实证地检验了美国社交距离政策的效率,并提供了由算法生成的建议。

Did Mortgage Forbearance Reach the Right Homeowners? Income and Liquid Assets Trends for Homeowners during the COVID-19 Pandemic 抵押贷款延期是否惠及了合适的房主?2019冠状病毒病大流行期间房主收入和流动资产趋势
Pub Date : 2020-12-03 DOI: 10.2139/ssrn.3742332

COVID-19 devastated the US labor market threatening homeowners’ ability to stay current on their mortgage. During the Great Recession, payment relief was more difficult to come by whereas the Coronavirus Aid, Relief, and Economic Security (CARES) Act provided most impacted homeowners with up to 12 months of payment relief if they attested to COVID-related hardship. However, the CARES Act did not cover everyone—it was silent on non-federally backed mortgage holders and those experiencing non-COVID related hardship. Furthermore, many borrowers were either not aware of mortgage relief options and/or were worried about potential balloon payments after forbearance ends. How well did this widespread intervention work? Did it reach all those who might have benefitted? Is there evidence of widespread moral hazard? Using checking account data linked to loan-level mortgage servicing data, we explore these questions. We find that while a third of homeowners in forbearance made all payments to date, a small fraction of homeowners not in forbearance did miss payments. Also, we find little evidence of widespread moral hazard. Families using forbearance to miss mortgage payments showed larger drops in total income than other homeowners and experienced income changes similar to those who have gone delinquent without the protection of forbearance. Also, families in forbearance were more likely to have lost labor income and received UI than families not in forbearance. Finally, we find that forbearance helped families with low levels of liquid assets to maintain their cash buffers. Together these results suggest that CARES Act mortgage forbearance policies helped homeowners experiencing financial hardship in a material way by allowing them to miss payments without adversely affecting their credit scores and maintain their small cash buffers in a world with a lot more economic uncertainty. In addition, these benefits came with little evidence of material moral hazard. However, there is room for improvement in future legislation as a small fraction of homeowners facing hardship did not benefit from forbearance and one main impediment was confusion around balloon payments. All in all the CARES Act forbearance policies appear so far to have been a large step in the right direction relative to policies during the Great Recession.
COVID-19摧毁了美国劳动力市场,威胁到房主继续偿还抵押贷款的能力。在大衰退期间,支付救济更难获得,而《冠状病毒援助、救济和经济安全(关怀)法案》为受影响最严重的房主提供长达12个月的支付救济,前提是他们证明自己有与冠状病毒相关的困难。然而,《关怀法案》并没有涵盖所有人——它对非联邦支持的抵押贷款持有人和那些经历与covid无关的困难的人保持沉默。此外,许多借款人要么不知道抵押贷款减免的选择和/或担心潜在的气球支付后,宽限期结束。这种广泛的干预效果如何?所有可能受益的人都收到了吗?是否有证据表明存在广泛的道德风险?使用与贷款级抵押贷款服务数据相关联的支票账户数据,我们将探讨这些问题。我们发现,到目前为止,有三分之一的延期还贷的房主支付了所有的还款,而一小部分没有延期还贷的房主确实错过了还款。此外,我们几乎没有发现普遍存在道德风险的证据。与其他房主相比,使用缓期还贷的家庭总收入下降幅度更大,他们的收入变化与那些没有获得缓期还贷保护的家庭相似。同时,相对于非禁欲家庭,禁欲家庭更有可能失去劳动收入并领取失业救济金。最后,我们发现,忍耐有助于流动性资产水平较低的家庭维持其现金缓冲。总之,这些结果表明,《关怀法案》的抵押贷款延期政策帮助房主在物质上经历了经济困难,允许他们错过付款,而不会对他们的信用评分产生不利影响,并在一个经济不确定性大大增加的世界中保持他们的小额现金缓冲。此外,这些好处几乎没有证据表明存在实质性的道德风险。然而,未来的立法还有改进的空间,因为一小部分面临困境的房主没有从宽限中受益,一个主要障碍是对气球付款的困惑。总而言之,到目前为止,与大衰退时期的政策相比,《关怀法案》的宽容政策似乎朝着正确的方向迈出了一大步。

Maternal Mortality Risk and Spousal Differences in the Demand for Children 产妇死亡风险和配偶对儿童需求的差异
Pub Date : 2020-12-01 DOI: 10.3386/w28220

Fertility decisions are often made by partners who may disagree. We develop a model in which an initial gender gap in ideal fertility prevents effective communication between spouses about the costs of childbearing incurred by women. This mechanism is likely to further widen the spousal disagreement over fertility in environments where maternal health risk is high and imperfectly observed. We design an intervention to experimentally vary exposure to information about maternal health costs to either the husband or the wife on a sample of approximately 500 couples in peri-urban Lusaka, in Zambia. At baseline, husbands display lower knowledge of maternal mortality and morbidity compared to their wives. At followup, about one year after the intervention, women whose husbands are treated experience a 43% reduction in the probability of being pregnant. Consistent with our hypothesis, men who are directly treated report lower desired fertility and have more accurate beliefs about their wife’s desired fertility than the husbands of treated women. Couples in which the husband is treated also increase communication about family planning, and experience greater marital satisfaction.
生育决定通常是由意见不一致的伴侣做出的。我们开发了一个模型,在这个模型中,理想生育能力的初始性别差距阻碍了配偶之间关于女性生育成本的有效沟通。在产妇健康风险高且观察不完全的环境中,这一机制可能进一步扩大配偶在生育问题上的分歧。我们设计了一项干预措施,在赞比亚卢萨卡城郊约500对夫妇的样本中,实验性地改变丈夫或妻子对孕产妇保健费用信息的了解程度。在基线时,丈夫对产妇死亡率和发病率的了解低于妻子。在干预后大约一年的随访中,丈夫接受治疗的女性怀孕的概率降低了43%。与我们的假设一致,与接受治疗的女性的丈夫相比,接受直接治疗的男性报告的期望生育能力较低,并且对妻子的期望生育能力有更准确的信念。对丈夫进行治疗的夫妇也会增加关于计划生育的沟通,并体验到更高的婚姻满意度。

Sovereign Debt Standstills 主权债务停滞不前
Pub Date : 2020-12-01 DOI: 10.3386/w28292
J. Hatchondo, L. Martinez, César Sosa‐Padilla
As a response to economic crises triggered by COVID-19, sovereign debt standstill proposals emphasize debt payment suspensions without haircuts on the face value of debt obligations. We quantify the effects of standstills using a standard default model. We find that a one-year standstill generates welfare gains for the sovereign equivalent to a permanent consumption increase of between 0.1% and 0.3%, depending on the initial shock. However, except when it avoids a default, the standstill also implies capital losses for creditors of between 9% and 27%, which is consistent with their reluctance to participate in these operations and indicates that this reluctance would persist even without a free-riding or holdout problem. Standstills also generate a form of “debt overhang” and thus the opportunity for a “voluntary debt exchange”: complementing the standstill with haircuts could reduce creditors’ losses and simultaneously increase welfare gains. Our results cast doubts on the emphasis on standstills without haircuts.
作为应对新冠肺炎引发的经济危机的措施,主权债务暂停方案强调在不削减债务面值的情况下暂停偿还债务。我们使用标准的默认模型来量化停顿的影响。我们发现,根据最初的冲击,一年的停滞为主权国家带来的福利收益相当于0.1%至0.3%的永久性消费增长。然而,除非它避免违约,否则停滞不前也意味着债权人的资本损失在9%到27%之间,这与他们不愿参与这些行动是一致的,并且表明即使没有搭便车或拒绝问题,这种不愿也会持续下去。停滞还会产生一种形式的“债务积压”,从而为“自愿债务交换”提供机会:通过削发弥补停滞可以减少债权人的损失,同时增加福利收益。我们的研究结果让人对强调静止不剪头发的做法产生了怀疑。

Shared Socioeconomic Pathways (SSPs) – Uncertainties and Challenges Post COVID-19 共享的社会经济路径——COVID-19后的不确定性和挑战
Pub Date : 2020-11-24 DOI: 10.2139/ssrn.3764350
Samraj Sahay
The paper provides an overview of the shared socioeconomic pathways (SSPs) and makes an effort to assess the challenges and uncertainties in the context of the disruptions caused by the COVID-19 pandemic. The narrative for the five SSPs are based on global assumptions and misses out on the country specific processes that could influence future socioeconomic trajectories. The assessment finds that the basic assumptions for macroeconomic growth - driven by human capital efficiency, no future growth disruptions and the future growth align with the historical development trajectories are vulnerable to risks posed by climate change and shocks imposed by pandemics. Also, SSPs do not factor in the sectoral contribution of agriculture, manufacturing and services which gets impacted through different channels during the pandemic and would have heterogeneous impacts across countries. The non-inclusion of disruption in projections under SSPs results in inflated growth and underestimation of vulnerability and economic loses. This is detrimental for choice of mitigation and adaptation policies and sustainable development pathways. The sudden change in internal migration due to shocks like pandemic which has essentially been an urban phenomenon and their impact on dynamics of urbanization has highlighted the importance of inclusion of migration in urbanization projection for SSPs. The uncertainties and challenges exposed by the pandemic have provided the opportunity to reassess the SSPs. There is an urgent need for a bottom-up approach of developing extended SSPs specific to the national or sub-national level and make projections by incorporating the country specific inputs in the model that are likely to be impacted by disruptions. This would provide a more realistic outcome that would be closer to the expected pathways and reduce uncertainties associated with the projections.
本文概述了共享社会经济路径(ssp),并努力评估在COVID-19大流行造成破坏的背景下面临的挑战和不确定性。对五个可持续发展战略方案的叙述是基于全球假设的,忽略了可能影响未来社会经济轨迹的国家具体进程。评估发现,宏观经济增长的基本假设——由人力资本效率驱动、未来增长不受干扰以及未来增长符合历史发展轨迹——很容易受到气候变化和流行病冲击带来的风险的影响。此外,可持续发展战略没有考虑农业、制造业和服务业的部门贡献,这些部门在大流行期间通过不同渠道受到影响,对各国的影响也不尽相同。在ssp下的预测中不包括破坏,导致了夸大的增长和对脆弱性和经济损失的低估。这不利于选择缓解和适应政策以及可持续发展途径。由于大流行病等冲击导致的国内移徙的突然变化(基本上是一种城市现象)及其对城市化动态的影响,突出了将移徙纳入可持续发展战略方案的城市化预测的重要性。大流行病带来的不确定性和挑战为重新评估战略战略计划提供了机会。目前迫切需要一种自下而上的方法,制定针对国家或国家以下一级的扩展的可持续战略方案,并通过将可能受到中断影响的国家具体投入纳入模型来进行预测。这将提供更现实的结果,更接近预期的路径,并减少与预测有关的不确定性。

The narrative for the five SSPs are based on global assumptions and misses out on the country specific processes that could influence future socioeconomic trajectories. The assessment finds that the basic assumptions for macroeconomic growth - driven by human capital efficiency, no future growth disruptions and the future growth align with the historical development trajectories are vulnerable to risks posed by climate change and shocks imposed by pandemics. Also, SSPs do not factor in the sectoral contribution of agriculture, manufacturing and services which gets impacted through different channels during the pandemic and would have heterogeneous impacts across countries. The non-inclusion of disruption in projections under SSPs results in inflated growth and underestimation of vulnerability and economic loses. This is detrimental for choice of mitigation and adaptation policies and sustainable development pathways. The sudden change in internal migration due to shocks like pandemic which has essentially been an urban phenomenon and their impact on dynamics of urbanization has highlighted the importance of inclusion of migration in urbanization projection for SSPs. The uncertainties and challenges exposed by the pandemic have provided the opportunity to reassess the SSPs. There is an urgent need for a bottom-up approach of developing extended SSPs specific to the national or sub-national level and make projections by incorporating the country specific inputs in the model that are likely to be impacted by disruptions. This would provide a more realistic outcome that would be closer to the expected pathways and reduce uncertainties associated with the projections.","PeriodicalId":20373,"journal":{"name":"Political Economy - Development: Health eJournal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85390897","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}

Mutual Fund Fragility, Dealer Liquidity Provisions, and the Pricing of Municipal Bonds 共同基金脆弱性、交易商流动性规定和市政债券定价

We study the period around the COVID-19 crisis to examine the potential fragility risks posed by mutual funds to the municipal bond market. Induced by unprecedented outflows from muni mutual funds, we show that bonds held by these funds trade substantially more and suffer greater price depressions than bonds not in muni funds. Dealer liquidity provision declines more in these bonds, exacerbating their market conditions. Importantly, such destabilizing effects have reshaped market perceptions on the fragility risks posed by mutual funds even after the normalization of muni fund flows. In the aftermath of the muni crisis, dealers reduce their inventories in bonds held by mutual funds and yield spreads widen notably in these bonds, especially when they are held by mutual funds with greater COVID-19 exposure and less liquid portfolios.
我们研究了COVID-19危机前后的时期,以检验共同基金对市政债券市场构成的潜在脆弱性风险。在市政共同基金空前资金外流的影响下,我们发现这些基金持有的债券比非市政基金持有的债券交易量大得多,价格下跌幅度也更大。这些债券的交易商流动性供应下降得更多,加剧了它们的市场状况。重要的是,这种不稳定效应重塑了市场对共同基金脆弱性风险的看法,即便是在市政基金流动正常化之后。在市政危机之后,交易商减少了共同基金持有的债券库存,这些债券的收益率差明显扩大,特别是当这些债券由COVID-19风险敞口较大、投资组合流动性较差的共同基金持有时。

MSR Under Exogenous Shock: The Case of COVID-19 Pandemic 外源性冲击下的MSR:以COVID-19大流行为例
Pub Date : 2020-11-03 DOI: 10.2139/ssrn.3724330

The EU implemented the Market Stability Reserve (MSR) in response to the 2008 financial crisis to deal with short-term impacts of future shocks, such as the Covid-19 pandemic. We link a model that intertemporally optimizes the handling of banked allowances every five years with one that simulates the annual working of the EU ETS including the MSR with its potential cancelling. Neglecting the pandemic, 2.16 billion allowances are cancelled. Accounting for the pandemic, 0.28 billion additional allowances are cancelled if the European economy fully recovers by 2021, which even overcompensates the 2020 drop in CO2 emissions. Additional cancelling increases when the pandemic lasts longer, meaning that the MSR even outperforms its initial purpose.
为应对2008年金融危机,欧盟实施了市场稳定储备(MSR),以应对未来冲击的短期影响,如Covid-19大流行。我们将一个每五年对银行配额处理进行跨期优化的模型与一个模拟包括MSR在内的欧盟碳排放交易体系年度运作及其潜在取消的模型联系起来。忽视大流行,21.6亿份津贴被取消。考虑到疫情,如果欧洲经济到2021年完全复苏,将取消2.8亿额外配额,这甚至超过了2020年二氧化碳排放量的下降。当大流行持续的时间越长,额外的取消就会增加,这意味着MSR甚至超过了其最初的目的。
