A Successful (Yet Somewhat Untested) Case of Disaster Financing: Terrorism Insurance Under TRIA, 2002–2020 灾难融资的成功案例:TRIA下的恐怖主义保险,2002-2020
E. Michel-Kerjan, H. Kunreuther
The Terrorism Risk Insurance Act (TRIA), passed at the end of 2002, established a public-private partnership between the US federal government, private insurers, and all commercial enterprises operating on US soil. Renewed and modified by the US Congress and the president in January 2015 until December 2020, the TRIA program requires insurers to offer terrorism insurance to their commercial policyholders while providing insurers with free up-front financial protection up to $100 billion against terrorist attacks in the United States. With the federal government providing a financial safety net, the private insurance sector can offer coverage against an uncertain risk that would otherwise be largely considered uninsurable, thus making terrorism insurance widely available and affordable. Overall premiums have been at about 2 to 6 percent of property premiums over the past four years, with the most significant increase recently for financial institutions (from 4 percent in 2012 to 9 percent in 2015). A significant portion of insurance policies, 23 percent according to a recent study by the US Treasury, which are typically those covering smaller firms, include terrorism coverage at no disclosed additional cost. TRIA is a successful case of public-private disaster risk financing that has received bipartisan political support. Yet it remains untested for large losses and it is unclear how the market and policymakers will react should another large-scale insured loss occur. TRIA also raises concerns about the indemnification of individual victims of a terrorist attack (in addition to workers’ compensation).
2002年底通过的《恐怖主义风险保险法》(TRIA)在美国联邦政府、私营保险公司和所有在美国境内经营的商业企业之间建立了一种公私合作伙伴关系。美国国会和总统于2015年1月对TRIA计划进行了更新和修改,直至2020年12月,该计划要求保险公司向其商业保单持有人提供恐怖主义保险,同时为保险公司提供高达1000亿美元的免费预先财务保护,以应对美国境内的恐怖袭击。在联邦政府提供金融安全网的情况下,私营保险部门可以针对不确定的风险提供保险,否则这些风险在很大程度上被认为是不可保险的,从而使恐怖主义保险广泛可用且负担得起。过去四年,总体保费占房地产保费的比例约为2%至6%,最近增幅最大的是金融机构(从2012年的4%增至2015年的9%)。根据美国财政部最近的一项研究,很大一部分保险单(23%)通常覆盖较小的公司,包括恐怖主义保险,没有披露额外费用。TRIA是公私灾害风险融资的成功案例,得到了两党的政治支持。然而,它仍未经受大规模损失的考验,而且尚不清楚,如果再次发生大规模保险损失,市场和政策制定者将如何反应。《反恐怖主义法》还对恐怖袭击的个别受害者的赔偿问题表示关切(除了工人赔偿外)。

Labor Mobility and Productivity: Evidence from Finance 劳动力流动与生产率:来自金融的证据
Roni Kisin, B. Hamilton
We use unique data on careers of investment managers to study the relation between labor markets and productivity differences across sectors in finance. We document significant labor mobility between mutual funds and hedge funds during the 1990s and 2000s. Descriptive evidence suggests potential inefficiencies in the allocation of skill and capital: switching from mutual funds to hedge funds results in large gains in return-based productivity and value-added. Hedge funds absorb mutual fund managers from the left and the right tails of the distribution of abnormal returns, lower Sharpe ratios, and higher volatility. To explain these patterns, we estimate a simple model of supply and demand for labor, with heterogeneous sector-specific skills. The model is identified using shocks to investor demand. Selection of low-skilled mutual managers into hedge funds was driven by a decrease in the mutual fund demand for such managers, an increase in hedge fund demand across the skill distribution, and idiosyncratic expected gains. Selection-adjusted average treatment effects show a much smaller hedge fund premium in return-based productivity and a we cannot reject a zero premium in value added.
我们使用投资经理职业生涯的独特数据来研究劳动力市场与金融部门生产率差异之间的关系。我们记录了20世纪90年代和21世纪初共同基金和对冲基金之间显著的劳动力流动性。描述性证据表明,技能和资本的配置可能效率低下:从共同基金转向对冲基金,会导致基于回报的生产率和附加值大幅提高。对冲基金从异常收益、较低夏普比率和较高波动性分布的左右两端吸收共同基金经理。为了解释这些模式,我们估计了一个简单的劳动力供需模型,其中包含了不同行业的特定技能。该模型通过对投资者需求的冲击来确定。对冲基金之所以选择低技能的共同基金经理,是因为共同基金对这类经理的需求减少,对冲基金在技能分布上的需求增加,以及特殊的预期收益。选择调整后的平均处理效应表明,对冲基金在基于回报的生产率方面的溢价要小得多,而且我们不能拒绝附加值为零的溢价。

The Role of Executive Cash Bonuses in Providing Individual and Team Incentives 高管现金奖金在提供个人和团队激励中的作用
W. Guay, John D. Kepler, David Tsui
Abstract Given CEOs’ substantial equity portfolios, much recent literature on CEO incentives regards cash-based bonus plans as largely irrelevant, begging the question of why nearly all CEO compensation plans include such bonuses. We develop a new measure of bonus plan incentives and show that performance sensitivities are much greater than prior estimates. We also test hypotheses regarding the role of bonuses in providing executives with individualized and team incentives. We find little evidence supporting the individualized incentives hypotheses but find consistent evidence that bonus plans appear to be used to encourage mutual monitoring and to facilitate coordination across the top management team as a whole.
鉴于CEO拥有大量的股票投资组合,最近关于CEO激励的许多文献认为,基于现金的奖金计划在很大程度上是无关紧要的,这就回避了一个问题:为什么几乎所有的CEO薪酬计划都包括这种奖金?我们开发了一种新的奖金计划激励措施,并表明绩效敏感性远远大于先前的估计。我们还测试了关于奖金在为高管提供个人和团队激励方面的作用的假设。我们发现很少有证据支持个性化激励假说,但发现一致的证据表明,奖金计划似乎被用来鼓励相互监督,并促进整个高层管理团队的协调。

Optimal Network Design for Inducing Effort 诱导努力的最优网络设计
Pinar Yildirim, Y. Wei, C. Bulte, Joy Lu
An increasing number of start-ups create online and offline shared goal communities for individuals with similar goals to work towards them in the company of others. Such platforms allow individuals to connect and share effort information under the premise that it is more likely for consumers to reach their goals if they can gauge their activity in line with others’ activities. We study the problem of designing such social communities. We find that co-action communities can motivate individuals to exert higher effort than they would have on their own, if they are appropriately located in a social network with sufficient social influence. Moreover, such communities can help consumers at a greater extent if they are of larger scale and if consumers in the community maintain sufficient levels of heterogeneity in how much they care about their goal progress individually. Our study also offers a method to determine a locally optimal network to design such communities and develops a model to study the conditions under which consumers can be motivated to exert effort towards a goal.
越来越多的创业公司为拥有相似目标的个人创建线上和线下的共同目标社区,让他们在他人的陪伴下为实现这些目标而努力。这些平台允许个人联系和分享努力信息,前提是如果消费者能够根据他人的活动来衡量自己的活动,他们就更有可能实现目标。我们研究设计这样的社会社区的问题。我们发现,如果个人处于一个具有足够社会影响力的社会网络中,那么合作社区可以激励个人比单独行动时付出更高的努力。此外,如果社区的规模更大,如果社区中的消费者在各自关心目标进展的程度上保持足够的异质性,那么这样的社区可以在更大程度上帮助消费者。我们的研究还提供了一种方法来确定一个局部最优网络来设计这样的社区,并开发了一个模型来研究消费者可以被激励为目标付出努力的条件。

Skill Transferability, Migration, and Development: Evidence from Population Resettlement in Indonesia 技能转移、移民和发展:来自印度尼西亚人口重新安置的证据
Samuel Bazzi, Arya B. Gaduh, Alexander D. Rothenberg, Maisy Wong
We use a natural experiment in Indonesia to provide causal evidence on the role of location-specific human capital and skill transferability in shaping the spatial distribution of productivity. From 1979-1988, the Transmigration Program relocated two million migrants from rural Java and Bali to new rural settlements in the Outer Islands. Villages assigned migrants from regions with more similar agroclimatic endowments exhibit higher rice productivity and nighttime light intensity one to two decades later. We find some evidence of migrants' adaptation to agroclimatic change. Overall, our results suggest that regional productivity differences may overstate the potential gains from migration.
我们在印度尼西亚进行了一项自然实验,为特定地点的人力资本和技能可转移性在塑造生产力空间分布中的作用提供因果证据。从1979年到1988年,“迁移计划”将爪哇和巴厘岛农村的200万移民重新安置到外岛的新农村定居点。来自农业气候禀赋相似地区的移民村庄在10至20年后表现出更高的水稻产量和夜间光照强度。我们发现了一些移民适应农业气候变化的证据。总体而言,我们的研究结果表明,地区生产率差异可能夸大了移民带来的潜在收益。

Does Gender Raise the Ethical Bar? Exploring the Punishment of Ethical Violations at Work 性别是否提高了道德标准?探讨对工作中违反职业道德行为的惩罚
J. Kennedy, M. McDonnell, Nicole M. Stephens
We investigate whether women are targets of more severe punishment than men following ethical violations at work. Using an experimental design, Study 1 finds evidence that ethical behavior is more strongly prescribed for women than for men, even when they occupy an identical professional role. Study 2 manipulates the gender of a manager in a hypothetical scenario and finds that women are punished more severely than men for ethical violations at work. It also tests the scope of our theory by asking whether women are punished more for errors in general, or only for intentional ethical violations. Using field data, Study 3 examines how severely attorneys are punished for violating the American Bar Association’s ethical rules. Female attorneys are punished more severely than male attorneys, after accounting for a variety of factors. Greater representation of women among decision-makers diminishes the gender disparity in punishment. Our research documents a new prescriptive stereotype faced by women and helps to explain the persistence of gender disparities in organizations. It highlights punishment severity as a novel mechanism by which institutions may derail women’s careers more than men’s.
我们调查了在工作中违反道德规范后,女性是否会比男性受到更严厉的惩罚。通过实验设计,研究1发现有证据表明,女性比男性更强烈地要求道德行为,即使他们占据相同的职业角色。研究2在一个假设的场景中操纵了经理的性别,发现女性在工作中因违反道德规范而受到的惩罚比男性更严重。它还测试了我们的理论的范围,通过询问女性是否因为一般的错误而受到更多的惩罚,还是仅仅因为故意违反道德规范。使用实地数据,研究3考察了律师因违反美国律师协会的道德规则而受到的严厉惩罚。考虑到各种因素后,女律师受到的惩罚比男律师更严重。女性在决策者中的更多代表减少了惩罚方面的性别差异。我们的研究记录了女性面临的一种新的规范性刻板印象,并有助于解释组织中持续存在的性别差异。它强调了严厉的惩罚是一种新的机制,通过这种机制,机构可能比男性更容易破坏女性的职业生涯。

V(CLV): Examining Variance in Models of Customer Lifetime Value V(CLV):检验客户终身价值模型的方差
D. McCarthy, P. Fader, Bruce G. S. Hardie
While accurate point estimation of customer lifetime value (CLV) has been the target of a large body of academic research, few have focused on the variance of CLV (V(CLV)), which represents the degree of uncertainty associated with a customer's expected CLV. This is ironic because academics have long known that V(CLV) is one of the most important characteristics that defines and differentiates customers from one another, affecting firms on many fundamental levels. No closed-form, forward-looking statistical procedures have been derived to estimate individual-level V(CLV). For the first time, the authors derive, predict, and validate V(CLV) using a powerful combination of stochastic models for the flow of transactions over time and the company's profit on each transaction. They provide these estimates for 561,100 customers of an omnichannel retailer tracked over a 2.25-year period, making this one of the largest-scale CLV analyses to date. They highlight the importance of V(CLV), analyze its relationship to observable summary statistics such as recency, frequency, and monetary value, and uncover many substantive variance-related insights regarding customer segmentation, scoring, targeting, and more.
虽然客户生命周期价值(CLV)的准确点估计一直是大量学术研究的目标,但很少有人关注CLV的方差(V(CLV)),它表示与客户期望的CLV相关的不确定性程度。这很讽刺,因为学者们早就知道,V(CLV)是定义和区分客户的最重要特征之一,在许多基本层面上影响着公司。没有封闭的、前瞻性的统计程序来估计个人水平的V(CLV)。作者首次使用一种强大的随机模型组合来推导、预测和验证V(CLV),该模型用于一段时间内的交易流和公司每笔交易的利润。他们对一家全渠道零售商的56.11万名顾客进行了2.25年的跟踪调查,使其成为迄今为止规模最大的CLV分析之一。他们强调了V(CLV)的重要性,分析了它与可观察的汇总统计数据(如近代性、频率和货币价值)的关系,并揭示了许多与方差相关的实质性见解,包括客户细分、评分、目标定位等。

Informational Uniqueness, Corporate Disclosure, and Information Environment 信息独特性、公司披露与信息环境
Jacky Chau
The study examines how the lack of comparable public peers (“informational uniqueness”) is related to a firm’s disclosure policy and information environment. Having less information spillover from other public firms may present an information deficiency if it is not compensated by other components of the information environment. Consistent with firms attempting to mitigate the information deficiency through strengthening their tacit commitment to continued disclosure, I find that informational uniqueness is associated with a higher propensity by firms to provide ongoing bundled guidance. Overall, I find a strong negative relationship between informational uniqueness and the quality of corporate information environment only among firms without regular bundled guidance. This suggests that, while informational uniqueness can generate significant information deficiency, firms with strong tacit disclosure commitment are able to largely compensate for the lack of information spillover from peers.
该研究考察了缺乏可比较的公众同行(“信息独特性”)与公司披露政策和信息环境之间的关系。来自其他上市公司的信息外溢较少,如果没有得到信息环境的其他组成部分的补偿,可能会出现信息不足。与公司试图通过加强他们对持续披露的默示承诺来减轻信息不足相一致,我发现信息独特性与公司提供持续捆绑指导的更高倾向相关。总体而言,我发现只有在没有定期捆绑指导的公司中,信息独特性与企业信息环境质量之间存在强烈的负相关关系。这表明,虽然信息独特性会产生显著的信息不足,但具有较强隐性披露承诺的企业能够在很大程度上弥补同行信息溢出的不足。

Retirement Financing: An Optimal Reform Approach 退休融资:最优改革途径
R. Hosseini, A. Shourideh
We study Pareto optimal policy reforms aimed at overhauling retirement financing as an integral part of the tax and transfer system. Our framework for policy analysis is a heterogeneous‐agent overlapping‐generations model that performs well in matching the aggregate and distributional features of the U.S. economy. We present a test of Pareto optimality that identifies the main source of inefficiency in the status quo policies. Our test suggests that lack of asset subsidies late in life is the main source of inefficiency when annuity markets are incomplete. We solve for Pareto optimal policy reforms and show that progressive asset subsidies provide a powerful tool for Pareto optimal reforms. On the other hand, earnings tax reforms do not always yield efficiency gains. We implement our Pareto optimal policy reform in an economy that features demographic change.

我们研究了帕累托最优政策改革,旨在将退休融资作为税收和转移支付系统的一个组成部分进行全面改革。我们的政策分析框架是一个异质主体重叠代模型,该模型在匹配美国经济的总量和分配特征方面表现良好。我们提出了一个帕累托最优性的测试,该测试确定了现状政策中效率低下的主要来源。我们的测试表明,当年金市场不完整时,晚年缺乏资产补贴是低效率的主要来源。我们求解了帕累托最优政策改革,并证明了累进式资产补贴为帕累托最优改革提供了有力的工具。另一方面,所得税改革并不总能带来效率提升。我们在一个以人口变化为特征的经济体中实施帕累托最优政策改革。在稳定状态下,改革使每一代人消耗的净资源的现值降低了约7%至11%。这些收益相当于一次性一次性转移到第一代,相当于GDP的10.5%。

Omnichannel Retail Operations with Buy-Online-and-Pickup-in-Store 全渠道零售业务,网上购买,店内提货
Fei Gao, Xuanming Su
Many retailers have recently started to offer customers the option to buy online and pick up in store (BOPS). We study the impact of the BOPS initiative on store operations. We build a stylized model where a retailer operates both online and offline channels. Consumers strategically make channel choices. The BOPS option affects consumer choice in two ways: by providing real-time information about inventory availability and by reducing the hassle cost of shopping. We obtain three findings. First, not all products are well-suited for in-store pickup; specifically, it may not be profitable to implement BOPS on products that sell well in stores. Second, BOPS enables retailers to reach new customers, but for existing customers, the shift from online fulfillment to store fulfillment may decrease profit margins when the latter is less cost effective. Finally, in a decentralized retail system where store and online channels are managed separately, BOPS revenue can be shared across channels to alleviate incentive conflicts; it is rarely efficient to allocate all the revenue to a single channel.
许多零售商最近开始为顾客提供网上购物和实体店提货的选择。我们研究了BOPS对商店运营的影响。我们建立了一个程式化的模型,其中零售商同时运营在线和离线渠道。消费者战略性地选择渠道。BOPS选项通过两种方式影响消费者的选择:提供关于库存可用性的实时信息,减少购物的麻烦成本。我们得到了三个发现。首先,并非所有产品都适合店内提货;具体来说,在商店销售良好的产品上实施BOPS可能没有利润。其次,BOPS使零售商能够接触到新客户,但对于现有客户来说,从在线履行到实体店履行的转变可能会降低利润率,因为后者的成本效益较低。最后,在实体店和线上渠道分开管理的去中心化零售系统中,BOPS收益可以跨渠道共享,缓解激励冲突;将所有收入分配给单一渠道很少是有效的。
