This paper studies the growing presence of private equity (PE) acquirers in the hospital industry. We examine employment, operational efficiency and patient outcomes at hospitals acquired by PE firms. While the total employment at target hospitals significantly declines, the proportion of physicians and nurses in the total workforce (skilled worker ratio) increases for hospitals acquired by a publicly traded PE backed hospital. Employment cuts also occur in hospitals acquired by non-PE acquirers, but skilled worker ratio does not increase in those hospitals. PE-backed acquirers, especially publicly traded ones, are also uniquely associated with reductions in overhead costs. Consistent with PE acquirers increasing skilled worker ratio, patient satisfaction scores do not decline at PE-acquired hospitals and even improve along some dimensions. In contrast, patient satisfaction significantly worsens at hospitals acquired by non-PE acquirers. Examining real patient outcomes, we find that PE acquirers are not associated with higher mortality and readmission rates at target hospitals than non-PE acquirers. Overall, our paper provides a comprehensive look at the role of PE acquirers in the hospital industry, and documents nuanced differences between PE and non-PE acquirers, as well as between PE backed acquirers with and without access to public capital markets.
本文研究了私募股权(PE)收购方在医院行业日益增长的存在。我们考察了私募股权公司收购的医院的就业、运营效率和患者结果。虽然目标医院的总就业人数显著下降,但在公开上市的私募股权支持医院收购的医院中,医生和护士在总劳动力中所占的比例(熟练工人比例)有所增加。非pe收购方收购的医院也会出现裁员,但这些医院的熟练工人比例没有增加。私募股权支持的收购方,尤其是上市公司,也与间接成本的降低有着独特的联系。与PE收购方提高熟练工人比例一致,PE收购医院的患者满意度得分没有下降,甚至在某些方面有所提高。相比之下,非pe收购者收购的医院患者满意度明显恶化。通过检查真实的患者结果,我们发现PE收购者在目标医院的死亡率和再入院率与非PE收购者无关。总体而言,我们的论文全面考察了私募股权收购方在医院行业中的作用,并记录了私募股权收购方与非私募股权收购方之间的细微差异,以及私募股权支持的收购方与未进入公共资本市场的收购方之间的细微差异。

Sector-Specific Shocks and the Expenditure Elasticity Channel During the COVID-19 Crisis 2019冠状病毒病危机期间的部门冲击和支出弹性渠道
Pub Date : 2020-05-15 DOI: 10.2139/ssrn.3593514

The COVID-19 economic crisis differs from past recessions in terms of the sectors and occupations that are being hit first. In this paper we propose a model with sectoral and occupational heterogeneity and non-homothetic preferences over sectors. That is, households' consumption bundles depend on income and they cut consumption on high income-elastic sectors when labor income falls. We first document that contact intensive occupations are concentrated in just a few, high-income-elasticity sectors. By contrast, production/manufacturing occupations are distributed widely across sectors. We then compare a COVID-19 type shock affecting service sectors first to a more ``standard" recession affecting manufacturing in our model calibrated to match the U.S. economy. Our main result is that the increase in labor income inequality in the COVID-19 recession is one and a half times the increase in a normal recession due to the fact that contact intensive service workers are low income and work mainly in high income-elasticity sectors.
新冠肺炎经济危机与以往经济衰退的不同之处在于,首当其冲的是哪些行业和职业。在本文中,我们提出了一个具有部门和职业异质性和非同质偏好的模型。也就是说,家庭的消费依赖于收入,当劳动收入下降时,他们会削减高收入弹性部门的消费。我们首先证明,接触密集型职业集中在少数几个高收入弹性部门。相比之下,生产/制造业职业在各个部门分布广泛。然后,我们将影响服务业的COVID-19型冲击与影响制造业的更“标准”的衰退进行比较,我们的模型经过校准,以匹配美国经济。我们的主要结果是,在COVID-19经济衰退中,劳动收入不平等的增加是正常经济衰退的1.5倍,这是因为接触密集型服务工人收入较低,主要在高收入弹性部门工作。

Factors Affecting Health Worker Density: Evidence from a Quantitative Cross-Country Analysis 影响卫生工作者密度的因素:来自定量跨国分析的证据
Pub Date : 2014-12-22 DOI: 10.2139/ssrn.2541690

In 2006 the World Health Organization identified 57 countries with critical shortage of health workforce. A number of cross-country studies have explored the effect of the health workforce density on countries’ health outcomes. However, little is known about the factors driving health workforce density. The objective of this study was to identify the factors affecting the density of health workforce, which would provide broader understanding of the underlying causes of this crisis and help formulate appropriate policies in order to mitigate the challenge. This study analysed data from 183 UN member countries to assess the association between the various demographic, economic and political factors and the health workforce density. Out of 183 countries, 66 (36%) had a heath workforce density below the WHO recommended threshold of 2.3 per 1,000 people. The adult literacy rate (p-value<0.01), total health expenditure (p-value<0.01) and social stability (p-value=0.04) are statistically significant. Total health expenditure had the greatest (33%) effect on the density of health workforce, followed by literacy rates (25%) and social stability (11%). This cross-country study provides a snapshot of the potential factors affecting health workforce density. Two of the three significant factors (adult literacy rate and social stability) are not directly related to countries’ health system, which indicates that a holistic and integrated approach is required in order to alleviate the health workforce crisis. Further studies triangulating various quantitative and qualitative data would extend the understanding of the topic.
2006年,世界卫生组织确定了57个卫生人力严重短缺的国家。一些跨国研究探讨了卫生人力密度对国家健康结果的影响。然而,人们对推动卫生人力密度的因素知之甚少。这项研究的目的是确定影响卫生人力密度的因素,这将有助于更广泛地了解这场危机的根本原因,并有助于制定适当的政策,以减轻挑战。这项研究分析了183个联合国成员国的数据,以评估各种人口、经济和政治因素与卫生人力密度之间的关系。在183个国家中,66个(36%)的卫生人力密度低于世卫组织建议的阈值,即每千人2.3人。成人识字率(p值<0.01)、卫生总支出(p值<0.01)和社会稳定(p值=0.04)均有统计学意义。卫生总支出对卫生人力密度的影响最大(33%),其次是识字率(25%)和社会稳定(11%)。这项跨国研究简要介绍了影响卫生人力密度的潜在因素。三个重要因素中的两个(成人识字率和社会稳定)与国家的卫生系统没有直接关系,这表明需要采取全面和综合的方法来缓解卫生人力危机。对各种定量和定性数据进行三角测量的进一步研究将扩展对该主题的理解。

Wages Anatomy. Labor Supply of Nurses and a Comparison with Physicians 工资解剖学。护士劳动力供给与医师的比较
Pub Date : 2014-11-30 DOI: 10.2139/ssrn.2536261

We estimate a dynamic discrete choice model of Registered Nurses’ labor supply with random terms. A distinguished feature of our model is that random terms are correlated over time and jobs (habit persistence). Past options and not only the past optimal choices matter for the current choices. Given observed incentives, we find that nurses are mobile when they are young (less than physicians), but there is also a weak tendency of higher mobility again when they are approaching retirement age. Wage increases have a modest impact on labor supply. The overall elasticity for nurses is close to zero (like for physicians). These low elasticities shadow for stronger responses, shifting labor away from part time jobs in the public and private sector towards full time jobs in the private sector. A change in taxation away from the progressive tax system towards a flat tax of 28% gives Registered Nurses a very modest incentive to shift their job to private hospitals. For physicians the impact is stronger.
我们用随机项估计注册护士劳动力供给的动态离散选择模型。我们模型的一个显著特征是随机项随时间和工作(习惯持久性)而相关。过去的选择不仅仅是过去的最佳选择对当前的选择有影响。考虑到观察到的激励因素,我们发现护士在年轻时(比医生少)具有流动性,但当他们接近退休年龄时,流动性也有微弱的趋势。工资增长对劳动力供给的影响不大。护士的整体弹性接近于零(就像医生一样)。这些低弹性为更强有力的应对措施蒙上了阴影,将劳动力从公共和私营部门的兼职工作转移到私营部门的全职工作。税收制度从累进税制转变为28%的单一税制,这给了注册护士一个非常温和的动机,促使他们将工作转移到私立医院。对医生来说,这种影响更大。

Outsourcing in the Healthcare Industry: Information Technology, Intellectual Property, and Allied Aspects 医疗保健行业的外包:信息技术、知识产权和相关方面
Pub Date : 2009-01-10 DOI: 10.2139/ssrn.1325885

The healthcare industry is being impacted by advances in information technology in four major ways: first, a broad spectrum of tasks that were previously done manually can now be done by computers faster, better, and at lower costs; second, some tasks can be outsourced to other countries using inexpensive communications technology; third, detailed analysis of longitudinal and societal healthcare data can now be analyzed in acceptable periods of time; and fourth, the best medical expertise can be made available to patients without the need to physically transport the patient to the doctor or vice versa. Still, there are many healthcare situations in which face-to-face interaction is the only practical way to render medical assistance. After considering a number of healthcare scenarios in which one or more of the co-authors were involved, this paper concludes that healthcare will increasingly use a portfolio approach comprised of three closely-coordinated components seamlessly interwoven together: healthcare tasks performed by humans on-site; healthcare tasks performed by humans off-site, including tasks performed in other countries; and healthcare tasks performed by computers without direct human involvement. This three-pronged approach will lead to better healthcare services at the most cost-economic rates; further, it will gradually incorporate some of the principles of the 24-Hour Knowledge Factory framework. Organizations that impede or otherwise restrict the use of this multifaceted approach will see higher healthcare costs, and will gradually become less competitive in the global marketplace, as is happening with non-adapting organizations in several other sectors of the economy. Finally, this paper deals with intellectual property and legal aspects related to the proposed three-pronged healthcare services paradigm.
信息技术的进步对医疗保健行业的影响主要体现在四个方面:首先,以前手工完成的广泛任务现在可以由计算机更快、更好、更低成本地完成;其次,利用廉价的通信技术,一些任务可以外包给其他国家;第三,现在可以在可接受的时间段内对纵向和社会医疗保健数据进行详细分析;第四,最好的医疗专业知识可以提供给病人,而不需要亲自把病人送到医生那里,反之亦然。尽管如此,在许多医疗保健情况下,面对面的互动是提供医疗援助的唯一实际方式。在考虑了一个或多个共同作者参与的许多医疗保健场景后,本文得出结论,医疗保健将越来越多地使用由三个紧密协调的组件无缝交织在一起的投资组合方法:由现场人员执行的医疗保健任务;人工在场外执行的医疗保健任务,包括在其他国家/地区执行的任务;医疗保健任务由计算机完成,无需人类直接参与。这种三管齐下的方法将以最具成本效益的价格提供更好的医疗保健服务;此外,它将逐步纳入24小时知识工厂框架的一些原则。阻碍或以其他方式限制使用这种多方面方法的组织将面临更高的医疗保健成本,并且在全球市场上的竞争力将逐渐下降,就像其他几个经济部门中不适应这种方法的组织所发生的那样。最后,本文讨论了与拟议的三管齐下的医疗保健服务范式相关的知识产权和法律方面的问题。
