In this paper we survey the historical record for over two centuries on the connection between expansionary fiscal policy and inflation. As a backdrop, we briefly lay out several theoretical approaches to the effects of fiscal deficits on inflation: the earlier Keynesian and monetarist approaches; and modern approaches incorporating expectations and forward looking behavior: unpleasant monetarist arithmetic and the fiscal theory of the price level. We find that the relationship between fiscal deficits and inflation generally holds in wartime when fiscally stressed governments resorted to the inflation tax. There were two peacetime episodes in the early twentieth century when bond financed fiscal deficits that were unbacked by future taxes seem to have greatly contributed to inflation: France in the 1920s and the recovery from the Great Recession in the 1930s in the U.S. In the post-World War II era a detailed examination of the Great Inflation in the 1960s and 1970s in the U.S. and the U.K. suggests that fiscal influences on monetary policy was a key factor. Finally we contrast the experience of the Great Financial Crisis of 2007-2008, when both expansionary fiscal and monetary policy did not lead to rising inflation, with the recent pandemic, which may involve the risks of fiscal dominance and future inflation.
本文考察了两个多世纪以来扩张性财政政策与通货膨胀之间关系的历史记录。在此背景下,我们简要列出了财政赤字对通胀影响的几种理论方法:早期的凯恩斯主义和货币主义方法;现代方法将预期和前瞻性行为结合起来:令人不快的货币主义算术和价格水平的财政理论。我们发现,财政赤字和通货膨胀之间的关系在战时通常成立,当财政紧张的政府诉诸通货膨胀税。20世纪初有两次和平时期,债券为财政赤字提供资金,而没有未来税收的支持,这似乎在很大程度上导致了通货膨胀:20世纪20年代的法国和30年代美国从大衰退中复苏。二战后,对20世纪60年代和70年代美国和英国大通胀的详细研究表明,财政对货币政策的影响是一个关键因素。最后,我们对比了2007-2008年金融危机的经历,当时扩张性财政和货币政策都没有导致通胀上升,而最近的大流行可能涉及财政主导和未来通胀的风险。

In this paper, we examine the effect of computer-assisted learning on students’ long-term development. We explore the implementation of the “largest ed-tech intervention in the world to date,” which connected China’s best teachers to more than 100 million rural students through satellite internet. We find evidence that exposure to the program improved students’ academic achievement, labor performance, and computer usage. We observe these effects up to ten years after program implementation. These findings indicate that education technology can have long-lasting positive effects on a variety of outcomes and can be effective in reducing the rural–urban education gap.

We report novel empirical estimates of the race-specific effects of larger police forces in the United States. Each additional police officer abates approximately 0.1 homicides. In per capita terms, effects are twice as large for Black versus White victims. Larger police forces also make fewer arrests for serious crimes, with larger reductions for crimes with Black suspects, implying that police force growth does not increase racial disparities among the most serious charges. At the same time, larger police forces make more arrests for low-level "quality-of-life" offenses, with effects that imply a disproportionate impact for Black Americans.
我们报告了美国大型警察部队对种族特定影响的新经验估计。每增加一名警察,就能减少大约0.1起凶杀案。按人均计算,黑人受害者受到的影响是白人受害者的两倍。警察队伍规模越大,严重犯罪的逮捕率越低,黑人犯罪嫌疑人的逮捕率越低,这意味着警察队伍规模的扩大并没有加剧最严重指控中的种族差异。与此同时,规模更大的警察部队逮捕了更多低级的“影响生活质量”的犯罪,这对美国黑人的影响更大。

This paper evaluates the long-run effects of Head Start using large-scale, restricted administrative data. Using the county rollout of Head Start between 1965 and 1980 and age-eligibility cutoffs for school entry, we find that Head Start generated large increases in adult human capital and economic self-sufficiency, including a 0.65-year increase in schooling, a 2.7 percent increase in high school completion, an 8.5 percent increase in college enrollment, and a 39 percent increase in college completion. These estimates imply sizable, long-term returns to investments in means-tested, public preschool programs.
本文使用大规模的、有限的行政数据来评估先导性教育的长期效果。利用1965年至1980年间各县率先推出的“领先计划”和入学年龄资格门槛,我们发现,“领先计划”大大提高了成人人力资本和经济自给自足,包括65年的受教育时间增加了0.65年,高中毕业率提高了2.7%,大学入学率提高了8.5%,大学毕业率提高了39%。这些估计意味着,对经过经济状况调查的公立学前教育项目的投资将获得可观的长期回报。

Job Satisfaction Over the Life Course 职业满意度贯穿一生
Pub Date : 2020-12-01 DOI: 10.3386/w28206
David G. Blanchflower, A. Bryson
We examine the relationship between union membership and job satisfaction over the life-course using data from the National Child Development Study (NCDS) tracking all those born in Great Britain in a single week in March in 1958 through to age 55 (2013). Data from immigrants as well as non-respondents to the original 1958 Perinatal Mortality Study (PMS) are added in later years. Conditioning on one’s social class at birth, together with one’s education and employment status, we find there is a significant negative correlation between union membership and job satisfaction that is apparent across the life-course. Lagged union membership status going back many years is negatively correlated with current job satisfaction, though its effects become statistically non-significant when conditioning on current union membership status. These results provide a different perspective to longitudinal studies showing short-term positive responses to switches in membership status. They are consistent with earlier work showing that this cohort of workers, and others before them, have persistently lower job satisfaction as union members compared to their non-union counterparts.
我们使用国家儿童发展研究(NCDS)的数据来研究工会会员资格和工作满意度之间的关系,该研究追踪了1958年3月的一周内出生在英国的所有人,直到55岁(2013年)。来自移民的数据以及1958年围产期死亡率研究(PMS)的非应答者的数据在后来的年份被添加。根据一个人出生时的社会阶层、受教育程度和就业状况,我们发现工会会员资格与工作满意度之间存在显著的负相关,这种负相关在整个生命过程中都很明显。多年前落后的工会会员身份与当前的工作满意度呈负相关,尽管当以当前的工会会员身份为条件时,其影响在统计上不显著。这些结果为纵向研究提供了不同的视角,显示了成员身份转换的短期积极反应。他们与早期的研究一致,表明这群工人,以及在他们之前的其他人,作为工会成员,与非工会成员相比,工作满意度持续较低。

Transhumant Pastoralism, Climate Change, and Conflict in Africa 非洲的游牧、气候变化和冲突
Pub Date : 2020-12-01 DOI: 10.3386/w28243

Arid regions of Africa are expanding by thousands of square kilometers a year, potentially disturbing pastoral routes that have been forged over a long period of time. This disturbance is often said to explain why “herder-farmer” conflicts have erupted in recent years, as pastoralists and agriculturalists compete for increasingly scarce resources. We examine this hypothesis by combining ecological and ethnographic data on the location of pastoral ethnic groups with grid-cell level data on violent conflict in Africa from 1989 to 2018. First, using ecological data, (i) we confirm that areas suited to both agriculture and pastoralism are particularly prone to conflict relative to either agricultural or pastoral areas alone; and (ii) we find that the effect of precipitation shocks on conflict in these agro-pastoral zones is negative at the country-level, but not at the cell-level. To explain this pattern, we compile data on the historical location of borders between both types of ethnic groups. We find that droughts in pastoral areas lead to conflict in neighboring agricultural areas. This spillover mechanism appears to explain much of the negative overall relationship between precipitation and conflict in the sample. It implies that agro-pastoral conflict is caused by the displacement of pastoral groups due to low precipitation in their homelands. This finding establishes one mechanism through which climate change can lead to more conflict in agro-pastoral zones.
非洲的干旱地区正以每年数千平方公里的速度扩张,这可能会扰乱长期以来形成的牧区路线。这种骚乱通常被认为可以解释为什么近年来牧民和农人争夺日益稀缺的资源而爆发“牧民-农民”冲突。我们通过将1989年至2018年非洲暴力冲突的网格级数据与牧民族群所在地的生态和人种学数据相结合来检验这一假设。首先,使用生态数据,(i)我们确认适合农业和畜牧业的地区特别容易发生冲突,相对于单独的农业或牧区;(ii)我们发现降水冲击对这些农牧区冲突的影响在国家层面上是负的,但在细胞层面上不是。为了解释这种模式,我们收集了两种民族之间边界的历史位置数据。我们发现牧区的干旱导致了邻近农业区的冲突。这种溢出机制似乎在很大程度上解释了样本中降水与冲突之间的负相关关系。这意味着农牧冲突是由于牧民群体因家乡降水少而流离失所造成的。这一发现建立了一种机制,通过这种机制,气候变化可能导致农牧区发生更多冲突。

Tobacco 21 (T-21) laws prohibit the sale of tobacco products to individuals under age 21. This study is the first to comprehensively examine the impacts of statewide T-21 laws on youth tobacco consumption, including spillovers to minor teens. Using data from the 2009-2019 Behavioral Risk Factor Surveillance Survey (BRFSS) and a difference-in-differences approach, we find that the enactment of a statewide T-21 law was associated with a 2.5 to 3.9 percentage-point decline in smoking participation among 18-to-20-year-olds. A causal interpretation of our estimates is supported by event-study analyses and falsification tests for young adults ages 21 and older. Next, using data from the 2009-2019 State Youth Risky Behavior Surveys (YRBS), we find that statewide T-21 laws reduced tobacco cigarette and electronic cigarette (e-cigarette) consumption among 18-year-old high school students. However, descriptive evidence suggests that the negative impact of T-21 laws on e-cigarette use among 18-year-olds may be partially blunted by an increase in borrowing e-cigarettes from others. Finally, we find that T-21 laws generate important spillovers including (i) a reduction in tobacco cigarette use among 16-to-17-year-olds, a group that relies heavily on the “social market” — including 18-year-old peers — to access tobacco, and (ii) reductions in both marijuana use and frequency of alcohol consumption among older teenagers.

烟草21 (T-21)法律禁止向21岁以下的个人出售烟草产品。这项研究是第一个全面检查全州T-21法律对青少年烟草消费的影响,包括对未成年青少年的溢出效应。利用2009-2019年行为风险因素监测调查(BRFSS)的数据和差异中的差异方法,我们发现,在全州范围内颁布T-21法律,与18至20岁青少年吸烟参与率下降2.5至3.9个百分点有关。事件研究分析和对21岁及以上年轻人的证伪检验支持了我们估计的因果解释。接下来,使用2009-2019年州青少年危险行为调查(YRBS)的数据,我们发现全州范围内的T-21法律减少了18岁高中生的卷烟和电子烟(电子烟)消费。然而,描述性证据表明,T-21法律对18岁青少年使用电子烟的负面影响可能会因向他人借用电子烟的增加而部分减弱。最后,我们发现T-21法律产生了重要的溢出效应,包括(i)减少了16至17岁青少年的卷烟使用,这是一个严重依赖“社会市场”的群体——包括18岁的同龄人——获得烟草,(ii)减少了大龄青少年使用大麻和饮酒的频率。国家经济研究局工作论文系列的机构订阅者和发展中国家的居民可以在www.nber.org免费下载本文。

Vertical Integration of Healthcare Providers Increases Self-Referrals and Can Reduce Downstream Competition: The Case of Hospital-Owned Skilled Nursing Facilities 医疗服务提供者的垂直整合增加了自我转诊,并可以减少下游竞争:医院拥有的熟练护理设施的案例

The landscape of the U.S. healthcare industry is changing dramatically as healthcare providers expand both within and across markets. While federal antitrust agencies have mounted several challenges to same-market combinations, they have not challenged any non-horizontal affiliations – including vertical integration of providers along the value chain of production. The Clayton Act prohibits combinations that “substantially lessen” competition; few empirical studies have focused on whether this is the source of harm from vertical combinations. We examine whether hospitals that are vertically integrated with skilled nursing facilities (SNFs) lessen competition among SNFs by foreclosing rival SNFs from access to the most lucrative referrals. Exploiting a plausibly exogenous shock to Medicare reimbursement for SNFs, we find that a 1 percent increase in a patient’s expected profitability to a SNF increases the probability that a hospital self-refers that patient (i.e., to a co-owned SNF) by 2.5 percent. We find no evidence that increased self-referrals improve patient outcomes or change post-discharge Medicare spending. Additional analyses show that when integrated SNFs are divested by their parent hospitals, independent rivals are less likely to exit. Together, the results suggest vertical integration in this setting may reduce downstream competition without offsetting benefits to patients or payers.
随着医疗保健提供商在市场内部和跨市场的扩张,美国医疗保健行业的格局正在发生巨大变化。虽然联邦反垄断机构对同一市场的合并提出了几项挑战,但他们没有挑战任何非横向的从属关系,包括沿生产价值链的供应商的垂直整合。《克莱顿法》禁止“大幅削弱”竞争的合并;很少有实证研究关注这是否是垂直组合的危害来源。我们检查医院是否垂直整合的熟练护理设施(snf)通过阻止竞争对手snf从最有利可图的转诊减少snf之间的竞争。利用医疗保险对SNF报销的合理外生冲击,我们发现,患者对SNF的预期盈利能力增加1%,医院将患者(即共同拥有的SNF)自我引用的可能性增加2.5%。我们没有发现证据表明增加的自我转诊改善了患者的预后或改变了出院后的医疗保险支出。另外的分析表明,当合并的snf被其母医院剥离时,独立的竞争对手退出的可能性较小。总之,研究结果表明,在这种情况下,垂直整合可能会减少下游竞争,而不会抵消患者或付款人的利益。

Exploiting a plausibly exogenous shock to Medicare reimbursement for SNFs, we find that a 1 percent increase in a patient’s expected profitability to a SNF increases the probability that a hospital self-refers that patient (i.e., to a co-owned SNF) by 2.5 percent. We find no evidence that increased self-referrals improve patient outcomes or change post-discharge Medicare spending. Additional analyses show that when integrated SNFs are divested by their parent hospitals, independent rivals are less likely to exit. Together, the results suggest vertical integration in this setting may reduce downstream competition without offsetting benefits to patients or payers.","PeriodicalId":19091,"journal":{"name":"NBER Working Paper Series","volume":"NS20 9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77829200","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}

Stay-at-Home Orders in a Fiscal Union 财政联盟中的居家命令
Pub Date : 2020-12-01 DOI: 10.2139/ssrn.3824491
Mario J. Crucini, Oscar O'Flaherty
State and local governments throughout the United States attempted to mitigate the spread of Covid-19 using stay-at-home orders to limit social interactions and mobility. We study the economic impact of these orders and their optimal implementation in a fiscal union. Using an event study framework, we find that stay-at-home orders caused a 4 percentage point decrease in consumer spending and hours worked. These estimates suggest a $10 billion decrease in spending and $15 billion in lost earnings. We then develop an economic SIR model with multiple locations to study the optimal implementation of stay-at-home orders. From a national welfare perspective, the model suggests that it is optimal for locations with higher infection rates to set stricter mitigation policies. This occurs as a common, national policy is too restrictive for the economies of mildly infected areas and causes greater declines in consumption and hours worked than are optimal.
美国各地的州和地方政府试图通过“居家令”来限制社会交往和流动,以缓解Covid-19的传播。我们研究了这些命令的经济影响及其在财政联盟中的最佳实施。使用事件研究框架,我们发现居家令导致消费者支出和工作时间减少了4个百分点。这些估计表明,支出减少100亿美元,收入损失150亿美元。然后,我们开发了一个具有多地点的经济SIR模型来研究居家令的最佳实施。从国家福利的角度来看,该模型表明,对于感染率较高的地区来说,制定更严格的缓解政策是最佳选择。这种情况发生的原因是,一项共同的国家政策对轻度感染地区的经济限制过于严格,导致消费和工作时间的下降幅度大于最佳水平。

We introduce a new survey module intended to complement and expand research on the causes and consequences of advanced technology adoption. The 2018 Annual Business Survey (ABS), conducted by the Census Bureau in partnership with the National Center for Science and Engineering Statistics (NCSES), provides comprehensive and timely information on the diffusion among U.S. firms of advanced technologies including artificial intelligence (AI), cloud computing, robotics, and the digitization of business information. The 2018 ABS is a large, nationally representative sample of over 850,000 firms covering all private, nonfarm sectors of the economy. We describe the motivation for and development of the technology module in the ABS, as well as provide a first look at technology adoption and use patterns across firms and sectors. We find that digitization is quite widespread, as is some use of cloud computing. In contrast, advanced technology adoption is rare and generally skewed towards larger and older firms. Adoption patterns are consistent with a hierarchy of increasing technological sophistication, in which most firms that adopt AI or other advanced business technologies also use the other, more widely diffused technologies. Finally, while few firms are at the technology frontier, they tend to be large so technology exposure of the average worker is significantly higher. This new data will be available to qualified researchers on approved projects in the Federal Statistical Research Data Center network.
我们引入了一个新的调查模块,旨在补充和扩大对采用先进技术的原因和后果的研究。由人口普查局与国家科学与工程统计中心(NCSES)合作进行的2018年年度商业调查(ABS)提供了有关人工智能(AI)、云计算、机器人技术和商业信息数字化等先进技术在美国公司之间传播的全面和及时的信息。2018年的ABS是一个大型的、具有全国代表性的样本,涵盖了所有私营、非农业经济部门的85万家公司。我们描述了ABS中技术模块的动机和发展,并提供了跨公司和部门的技术采用和使用模式的第一手资料。我们发现数字化相当普遍,云计算的一些使用也是如此。相比之下,先进技术的采用很少,而且通常倾向于规模更大、更老的公司。采用模式与日益复杂的技术层次结构一致,其中大多数采用人工智能或其他先进商业技术的公司也使用其他更广泛传播的技术。最后,虽然很少有公司处于技术前沿,但它们往往规模很大,因此普通工人的技术暴露程度要高得多。这些新数据将提供给联邦统计研究数据中心网络中经批准项目的合格研究人员。
