New York City has seen a great deal of COVID-19 cases and deaths since the first positive test in March. This paper analyzes ZIP-code level COVID-19 outcomes with 2018 American Community Survey neighborhood data. I find residents of poor ZIP-codes and ZIP-codes with a greater fraction of the population identifying as black are more likely to test positive, more likely to die, and less likely to get tested for the virus. Such raises questions of how the virus spreads, how testing is allocated, and whether the cost of testing is different across different socioeconomic groups.
自3月份首次检测呈阳性以来,纽约市出现了大量COVID-19病例和死亡病例。本文利用2018年美国社区调查邻里数据分析邮政编码级别的COVID-19结果。我发现,邮政编码较差的地区和邮政编码中黑人人口比例较大的地区的居民更有可能被检测出阳性,更有可能死亡,更不可能接受病毒检测。这就提出了病毒如何传播、如何分配检测以及不同社会经济群体的检测成本是否不同的问题。

Housing Cycle and Firm Investment: International Firm-level Evidence 房地产周期与企业投资:国际企业层面的证据
Pub Date : 2020-05-28 DOI: 10.2139/ssrn.3612520
Hyunduk Suh, Jin Young Yang
We analyze international firm-level data to examine the relationship between housing cycle and firm capital expenditure or R&D spending. We use the housing price component independent of firms’ investment opportunity and credit supply shocks, obtained by historical decomposition of a structural VAR, as the key explanatory variable. The baseline results support the existence of the collateral channel as housing price growth and firm investment exhibit a positive relationship. This collateral channel is more distinct for capital expenditure than R&D spending, and in housing market downturns than booms. Another notable finding is that despite the collateral channel, large housing price booms are detrimental to investment, which suggests a possible reallocation of resources from the production sector to the housing sector during those phases. Moreover, various firm-specific and country-specific characteristics are found to affect the housing price-investment relationship. Small firms and firms with stronger investment opportunities respond more sensitively to housing price shocks. Countries that rely more on bank financing, collateralized lending, and with higher LTV restraint, display a larger collateral effect in capital expenditure.
我们分析了国际企业层面的数据来检验住房周期与企业资本支出或研发支出之间的关系。我们使用独立于企业投资机会和信贷供应冲击的房价成分,通过结构性VAR的历史分解获得,作为关键的解释变量。基准结果支持抵押渠道的存在,房价增长与企业投资呈现正相关关系。这种担保渠道在资本支出方面比在研发支出方面更为明显,在房地产市场低迷时期比在繁荣时期更为明显。另一个值得注意的发现是,尽管存在抵押品渠道,但房价大幅上涨不利于投资,这表明在这些阶段,资源可能会从生产部门重新配置到住房部门。此外,还发现各种企业和国家特征会影响房价-投资关系。小企业和投资机会较强的企业对房价冲击的反应更为敏感。越是依赖银行融资、抵押贷款和LTV约束程度越高的国家,其资本支出的抵押效应越大。

Do Compulsory Schooling Laws Always Work? A Study of Youth Crime in Brazilian Municipalities 义务教育法律总是有效吗?巴西城市青少年犯罪研究
Pub Date : 2020-04-06 DOI: 10.2139/ssrn.3568302

We examine if compulsory schooling laws (CSL) necessarily lower crimes. We focus on violent youth crime (homicides by assault and guns) among 15-19 years age group in all Brazilian municipalities over 2000-13, taking advantage of the 2009 Brazilian Constitutional Amendment that required introduction of compulsory high schooling of 15-17-year-olds by 2016. Only about 53% municipalities adopted the Amendment by 2013. Difference-in-difference estimates with municipality fixed effects to account for the endogenous adoption of the Amendment by municipalities show small treatment effects for homicides, but insignificant effects for homicide rates in the full sample. In the absence of any significant increase in income/employment among this age group, we attribute this to the incapacitation effect of CSL, which was, however, weakened by overcrowding in day and night schools in treated municipalities after 2009. In contrast, poorer treated municipalities witnessed increased class size, worse school performance and increased crime too. The crime reduction effects of CSL thus crucially depend on whether/how it affects class size and school quality especially in less promising jurisdictions.
我们研究义务教育法(CSL)是否必然降低犯罪。我们利用2009年巴西宪法修正案要求在2016年之前对15-17岁的青少年实行义务高中教育的规定,重点关注2000- 2013年巴西所有城市15-19岁年龄组的青少年暴力犯罪(袭击和枪支杀人)。到2013年,只有53%的市政当局采纳了该修正案。考虑到自治市对修正案的内生采用,考虑自治市固定效应的差异估计显示,对杀人案的处理效果很小,但对整个样本的杀人案率的影响不显著。在这一年龄组的收入/就业没有任何显著增长的情况下,我们将其归因于CSL的失能效应,然而,2009年之后,受治疗城市的日夜学校过度拥挤削弱了这一效应。相比之下,待遇较差的城市班级规模扩大,学校表现更差,犯罪率也有所上升。因此,CSL减少犯罪的效果关键取决于它是否/如何影响班级规模和学校质量,特别是在不太有前途的司法管辖区。

Effects of the Affordable Care Act Dependent Coverage Mandate on Health Insurance Coverage for Individuals in Same-Sex Couples 《平价医疗法案》对同性伴侣个人健康保险覆盖范围的影响
Pub Date : 2020-04-01 DOI: 10.3386/w26978

A large body of research documents that the 2010 dependent coverage mandate of the U.S. Affordable Care Act was responsible for significantly increasing health insurance coverage among young adults. No prior research has examined whether sexual minority young adults also benefitted from the dependent coverage mandate despite previous studies showing lower health insurance coverage among sexual minorities. Our estimates from the American Community Survey, using difference-in-differences and event study models, show that men in same-sex couples aged 21-25 experienced a significantly greater increase in the likelihood of having any health insurance after 2010 than older, 27- to 31-year-old men in same-sex couples. This increase is concentrated among employer-sponsored insurance, and it is robust to permutations of periods and age groups. Effects for women in same-sex couples and men in different-sex couples are smaller than the associated effects for men in same-sex couples. These findings confirm the broad effects of expanded dependent coverage and suggest that eliminating the federal dependent mandate could reduce health insurance coverage among young adult sexual minorities in same-sex couples.
大量研究表明,2010年《美国平价医疗法案》(U.S. Affordable Care Act)的家属保险授权,是大幅提高年轻人医疗保险覆盖率的原因。尽管之前的研究表明性少数群体的医疗保险覆盖率较低,但此前没有研究调查过性少数群体的年轻人是否也从家属保险中受益。我们根据美国社区调查(American Community Survey)的估计,使用差异中的差异和事件研究模型,表明21-25岁的同性伴侣中的男性在2010年之后拥有任何医疗保险的可能性明显高于年龄较大的27- 31岁的同性伴侣中的男性。这种增长主要集中在雇主赞助的保险中,而且对不同时期和年龄组的排列都很强劲。对同性伴侣中的女性和异性伴侣中的男性的影响小于对同性伴侣中的男性的相关影响。这些发现证实了扩大受抚养人覆盖范围的广泛影响,并表明取消联邦受抚养人强制令可能会减少同性伴侣中年轻成年性少数群体的健康保险覆盖范围。

One Child Town: The Health Care Exceptionalism Case against Agglomeration Economies 一孩小镇:针对集聚经济的医疗例外主义案例
Pub Date : 2020-03-24 DOI: 10.26054/0D-0BDW-3939

This Article offers an extended rebuttal to the suggestion to move residents away from dying communities to places with greater economic promise. Rural America, arguably, is one of those dying places. A host of strategies aim to shore up those communities and make them more economically viable. But one might ask, “Why bother?” In similar vein, David Schleicher’s provocative 2017 Yale Law Journal article, Stuck! The Law and Economics of Residential Stagnation urged dismantling a host of state and local government laws operating as barriers to migration by Americans from failing economies to robust agglomeration economies. But Schleicher said little about the fate of the places left behind. Schleicher’s article drew a number of pointed responses, urging the value and preservation of Small Town America. But those arguments failed fully to meet the rational economic thesis, countering instead with more sentimental or humanitarian concerns. This article offers a way to reconcile the two views, refracted through a health care lens. Health care is a particularly apt perspective for considering the question whether America’s rural places are worth saving because it necessarily, under longstanding U.S. policy preferences, walks the line between the economic principles and human rights; individual responsibility and communitarian values; the rational actor and the deserving recipient of aid. The health care exceptionalism case against agglomeration economies urges consideration of the real, quantifiable costs of migration and, correlatively, value of home, as well as the market imperfections inherent in health care and, even more so, in rural health care.
这篇文章对把居民从垂死的社区搬到有更大经济前景的地方的建议提出了广泛的反驳。可以说,美国农村是那些垂死的地方之一。一系列战略旨在支持这些社区,使它们在经济上更具可行性。但有人可能会问:“何必这么麻烦?”同样,大卫·施莱彻在2017年《耶鲁法律杂志》上发表了一篇挑衅性的文章《卡住了!》《居住停滞的法律和经济学》敦促废除许多州和地方政府的法律,这些法律阻碍了美国人从不景气的经济体向强劲的集聚经济体迁移。但施莱歇尔几乎没有谈到这些地方的命运。施莱歇尔的文章引起了许多尖锐的回应,敦促重视和保护美国小镇。但这些论点未能完全符合理性的经济命题,而是以更多的情感或人道主义关切来反驳。本文提供了一种通过医疗保健镜头来调和这两种观点的方法。在考虑美国农村地区是否值得拯救的问题时,医疗保健是一个特别合适的视角,因为根据美国长期以来的政策偏好,它必须在经济原则和人权之间走一条线;个人责任和社区价值观;理性的行为者和理应接受援助的人。反对集聚经济的卫生保健例外主义案例敦促考虑移民的实际、可量化成本,以及相关的家庭价值,以及卫生保健固有的市场缺陷,农村卫生保健更是如此。

The Response to Dynamic Incentives in Insurance Contracts with a Deductible: Evidence from a Differences-in-Regression-Discontinuities Design 具有免赔额的保险契约对动态激励的反应:来自回归-不连续差异设计的证据
Pub Date : 2020-03-01 DOI: 10.2139/ssrn.3568312

We develop a new approach to quantify how patients respond to dynamic incentives in health insurance contracts with a deductible. Our approach exploits two sources of variation in a differences-in-regression-discontinuities design: deductible contracts reset at the beginning of the year, and cost-sharing limits change over the years. Using rich claims-level data from a large Dutch health insurer we find that individuals are forward-looking. Changing dynamic incentives by increasing the deductible by €100 leads to a reduction in healthcare spending of around 3% on the first days of the year and 6% at the annual level. The response to dynamic incentives is an important part of the overall effect of cost-sharing schemes on healthcare expenditures- much more so than what the previous literature has suggested.
我们开发了一种新的方法来量化患者如何对健康保险合同中具有免赔额的动态激励作出反应。我们的方法利用了回归不连续性差异设计中的两个变化来源:免赔额合同在年初重新设置,以及成本分摊限制逐年变化。利用荷兰一家大型健康保险公司的丰富索赔数据,我们发现个人是具有前瞻性的。通过将免赔额增加100欧元来改变动态激励机制,可以在年初减少约3%的医疗保健支出,在年度水平上减少6%。对动态激励的反应是成本分摊方案对医疗支出的总体影响的重要组成部分——比以前的文献所建议的要重要得多。

The Coronavirus and the Great Influenza Epidemic - Lessons from the 'Spanish Flu' for the Coronavirus's Potential Effects on Mortality and Economic Activity 冠状病毒和大流感——从“西班牙流感”中吸取的教训:冠状病毒对死亡率和经济活动的潜在影响

Mortality and economic contraction during the 1918-1920 Great Influenza Pandemic provide plausible upper bounds for outcomes under the coronavirus (COVID-19). Data for 48 countries imply flu-related deaths in 1918-1920 of 40 million, 2.1 percent of world population, implying 150 million deaths when applied to current population. Regressions with annual information on flu deaths 1918-1920 and war deaths during WWI imply flu-generated economic declines for GDP and consumption in the typical country of 6 and 8 percent, respectively. There is also some evidence that higher flu death rates decreased realized real returns on stocks and, especially, on short-term government bills.
1918-1920年流感大流行期间的死亡率和经济萎缩为冠状病毒(COVID-19)下的结果提供了合理的上限。48个国家的数据表明,1918-1920年与流感有关的死亡人数为4000万,占世界人口的2.1%,如果适用于目前的人口,这意味着死亡人数为1.5亿。对1918-1920年流感死亡人数和第一次世界大战期间战争死亡人数的年度信息进行回归表明,在典型的国家,流感导致的GDP和消费分别下降了6%和8%。还有一些证据表明,流感死亡率的上升降低了股票,尤其是短期政府债券的实际回报率。

Regulating Conflicts of Interest through Public Disclosure: Evidence from a Physician Payments Sunshine Law 通过公开披露规范利益冲突:来自医生报酬阳光法的证据
Pub Date : 2020-02-16 DOI: 10.2139/ssrn.3539990
Matthew Chao, Ian Larkin
Hospital and health care administrators have often named prescription drug costs as one of their largest cost problems. Relatedly, a significant body of research demonstrates that meals and honoraria from pharmaceutical firms to physicians leads to higher prescribing of expensive, brand name drugs. Some administrators and scholars have advocated for mandatory disclosure of these payments in order to reduce this conflict of interest, but many practitioners believe disclosure has little effect on prescribing. This paper uses a quasi-experiment of a 2009 payment disclosure policy in Massachusetts to estimate the causal impact of public disclosure on prescribing. The comprehensive dataset includes all retail prescriptions for 262 drugs in 9 drug classes written by 5730 physicians in five states over 48 months. We show a significant post-disclosure reduction in brand name drug prescriptions by Massachusetts physicians, relative to control doctors in other states. These effects are driven by heavy prescribers of brand name drugs in the pre-policy period, particularly for drugs with large pre-policy sales forces. Effects are also detected before the first data were released, implying that the effects are not because patients or administrators responded to the disclosed payments. Instead, some physicians may have reduced payments after disclosure is mandated, leading to changes in their prescriptions. Taken in tandem with the many studies showing that industry payments influence prescribing, this study suggests a strong role for mandatory public disclosure in reducing conflicts of interest in medicine and costly prescribing of brand name drugs.
医院和卫生保健管理人员经常将处方药成本列为他们最大的成本问题之一。与此相关的是,大量研究表明,制药公司向医生提供的餐费和酬金会导致开出更多昂贵的品牌药物。一些管理人员和学者主张强制披露这些付款,以减少这种利益冲突,但许多从业者认为披露对处方的影响很小。本文采用2009年马萨诸塞州付款披露政策的准实验来估计公开披露对处方的因果影响。该综合数据集包括5个州5730名医生在48个月内撰写的9种药物类别262种药物的所有零售处方。我们显示,与其他州的对照医生相比,马萨诸塞州医生在披露品牌药物处方后显著减少。这些影响是由政策出台前大量开处方的品牌药物所驱动的,特别是对于那些在政策出台前拥有大量销售力量的药物。在第一批数据发布之前,效果也被检测到,这意味着效果不是因为患者或管理人员对披露的付款做出了反应。相反,一些医生可能在强制披露后减少了支付,导致他们的处方发生了变化。结合许多表明行业支付影响处方的研究,该研究表明,强制性公开披露在减少医药利益冲突和昂贵的品牌药物处方方面发挥着重要作用。

Relatedly, a significant body of research demonstrates that meals and honoraria from pharmaceutical firms to physicians leads to higher prescribing of expensive, brand name drugs. Some administrators and scholars have advocated for mandatory disclosure of these payments in order to reduce this conflict of interest, but many practitioners believe disclosure has little effect on prescribing. This paper uses a quasi-experiment of a 2009 payment disclosure policy in Massachusetts to estimate the causal impact of public disclosure on prescribing. The comprehensive dataset includes all retail prescriptions for 262 drugs in 9 drug classes written by 5730 physicians in five states over 48 months. We show a significant post-disclosure reduction in brand name drug prescriptions by Massachusetts physicians, relative to control doctors in other states. These effects are driven by heavy prescribers of brand name drugs in the pre-policy period, particularly for drugs with large pre-policy sales forces. Effects are also detected before the first data were released, implying that the effects are not because patients or administrators responded to the disclosed payments. Instead, some physicians may have reduced payments after disclosure is mandated, leading to changes in their prescriptions.

Although industrial plants, known as Toxic Release Inventory (TRI) sites, exist in every major city of the United States releasing billions of pounds of toxic substances annually, there is little evidence about how these pollutants might harm child development and children's long run outcomes. Using the detailed geocoded data that follows national representative cohorts of children born to the NLSY respondents over time with detailed information on families, locations, health, disability and labor market outcomes, I compare siblings who were gestating before versus after a TRI site opened or closed within one mile of their home. In other words, I compare siblings in the same family whose family does not move between births where one or more child was exposed to TRI pollution during gestation and other siblings were not exposed because the plant opened or closed in between the conceptions of different children in the same family. I find that children who were exposed prenatally to TRI pollution have lower wages, are more likely to be in poverty as adults, have fewer years of completed education, are less likely to graduate high school, and are more likely to have a disability.
尽管被称为有毒物质排放清单(TRI)站点的工业工厂存在于美国的每个主要城市,每年释放数十亿磅的有毒物质,但几乎没有证据表明这些污染物如何损害儿童的发育和儿童的长期结果。使用详细的地理编码数据,跟踪NLSY受访者所生儿童的全国代表性队列,并提供有关家庭,地点,健康,残疾和劳动力市场结果的详细信息,我比较了在TRI站点开放或关闭之前与之后怀孕的兄弟姐妹在他们家一英里内。换句话说,我比较的是同一家庭的兄弟姐妹,他们的家庭没有搬家,其中一个或多个孩子在怀孕期间暴露在三氮污染中,而其他兄弟姐妹没有暴露在三氮污染中,因为工厂在同一家庭不同孩子的怀孕期间开放或关闭。我发现,产前暴露于TRI污染的儿童工资较低,成年后更有可能陷入贫困,完成教育的年数更少,高中毕业的可能性更小,而且更有可能患有残疾。
