Most Western countries use a single discount rate to evaluate public investments and policies. This ignores the cost of risk, in a world where most risk markets exhibit surprisingly large prices of risk. The current discounting guidelines generate a misallocation of capital that entails a large welfare cost. We claim that the well-established asset pricing literature provides a strong normative justification in favor of risk-adjusting discount rates. More specifically, project-specific discount rates should be increasing in the income elasticity of the project's net benefit. This will favor projects whose net benefit materializes preferentially in low-income states, thereby recognizing their insurance benefit ex ante. The intuition is simple, the welfare benefit of the reform is large, and the methodology only requires evaluators to estimate an income elasticity on top of what is required in the current approach. It is time to fix our public discounting systems. Expected final online publication date for the Annual Review of Financial Economics, Volume 15 is November 2023.

大多数西方国家使用单一贴现率来评估公共投资和政策。这忽略了风险成本,在这个世界上,大多数风险市场都表现出惊人的高风险价格。现行的贴现准则导致资本配置不当,从而带来巨大的福利成本。我们声称,成熟的资产定价文献为风险调整贴现率提供了强有力的规范性理由。更具体地说,项目的具体贴现率应该增加项目净收益的收入弹性。这将有利于净福利优先在低收入州实现的项目,从而提前确认其保险福利。直觉很简单,改革的福利效益很大,方法只需要评估人员在当前方法要求的基础上估计收入弹性。是时候修复我们的公共折扣系统了。《金融经济学年度评论》第15卷预计最终在线出版日期为2023年11月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

The past half-century has seen major shifts in inflation expectations, how inflation comoves with the business cycle, and how stocks comove with Treasury bonds. Against this backdrop, we review the economic channels and empirical evidence on how inflation is priced in financial markets. Not all inflation episodes are created equal. Using a New Keynesian model, we show how “good” inflation can be linked to demand shocks and “bad” inflation to cost-push shocks driving the economy. We then discuss asset pricing implications of “good” and “bad” inflation. We conclude by providing an outlook for inflation risk premia in the world of newly rising inflation.

在过去的半个世纪里,通胀预期发生了重大变化,通胀如何与商业周期相协调,股票如何与国债相协调。在此背景下,我们回顾了通胀如何在金融市场定价的经济渠道和经验证据。并不是所有的通胀都是一样的。使用新凯恩斯主义模型,我们展示了“好的”通胀如何与需求冲击联系在一起,“坏的”通胀如何与驱动经济的成本推动冲击联系在一起。然后我们讨论了“好”和“坏”通胀对资产定价的影响。最后,我们提供了一个在新的通货膨胀上升的世界通货膨胀风险溢价的前景。《金融经济学年度评论》第15卷的最终在线出版日期预计为2023年11月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

How to Use Microdata for Macro-Finance 如何将微数据用于宏观金融

Financial frictions generate misallocation of resources across firms by restricting productive firms’ access to capital. This article reviews the literature that estimates the aggregate losses generated by such misallocation. The first approach relies on structural estimations: A model of firm dynamics with financial frictions is estimated and used to compare efficiency in the actual economy with a counterfactual with perfect financial markets. We argue that robustness is a central concern for this structural literature. We discuss ways to analyze robustness in structural estimation (using well-identified moments and analyzing sensitivity to moments). The second approach relies on sufficient statistics, namely formulas that measure misallocation using simple empirical statistics and that are valid for a class of models. We discuss key contributions in that space, the generality of this approach, and the conditions under which it is valid. Sufficient statistic approaches are simpler and more robust, but they come at a cost: The range of counterfactual analyses that can be explored is more limited. Expected final online publication date for the Annual Review of Financial Economics, Volume 15 is November 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
金融摩擦通过限制生产企业获得资本的途径,在企业之间产生资源错配。本文回顾了估计这种分配不当造成的总损失的文献。第一种方法依赖于结构性估计:对具有金融摩擦的企业动态模型进行估计,并用于比较实际经济与具有完美金融市场的反事实经济的效率。我们认为,稳健性是这个结构文献的中心问题。我们讨论了分析结构估计鲁棒性的方法(使用良好识别的矩和分析对矩的敏感性)。第二种方法依赖于充分的统计数据,即使用简单的经验统计来衡量分配不当的公式,并且对一类模型有效。我们将讨论该领域的关键贡献、该方法的普遍性以及该方法有效的条件。充分的统计方法更简单、更可靠,但它们是有代价的:可以探索的反事实分析的范围更有限。《金融经济学年度评论》第15卷的最终在线出版日期预计为2023年11月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

We explain the mechanics of smart contracts. We then highlight the benefits of smart contracts, such as overcoming commitment problems. We also discuss limitations, such as the difficulty for smart contracts to access information external to the blockchain and the difficulty of integrating smart contract code with traditional legal enforcement. We further highlight how the absence of a trusted intermediary inflates implementation costs for blockchain applications. We conclude with a discussion of the most prominent smart contract applications in decentralized finance: token issuance (e.g., initial coin offerings, nonfungible tokens), decentralized exchanges, and protocols for loanable funds. Our survey covers both institutional details and relevant literature. Expected final online publication date for the Annual Review of Financial Economics, Volume 15 is November 2023.

我们将解释智能合约的机制。然后,我们强调了智能合约的好处,例如克服承诺问题。我们还讨论了限制,例如智能合约访问区块链外部信息的难度,以及将智能合约代码与传统执法相结合的难度。我们进一步强调了缺乏可信中介如何增加区块链应用程序的实施成本。最后,我们讨论了去中心化金融中最突出的智能合约应用:代币发行(例如,初始代币发行、不可替代代币)、去中心化交易所和可贷款资金协议。我们的调查涵盖了制度细节和相关文献。《金融经济学年度评论》第15卷的最终在线出版日期预计为2023年11月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

This article surveys the recent empirical literature on historical banking crises, defined as events taking place before 1980. Advances in data collection and identification have provided new insights into the causes and consequences of crises both immediately and over the long run. We highlight three overarching threads that emerge from the literature: First, leverage in the financial system is a systematic precursor to crises; second, crises have sizable negative effects on the real economy; and third, government interventions can ameliorate these effects. Contrasting historical episodes reveals that the process of crisis formation and evolution varies significantly across time and space. Thus, we also highlight specific institutions, regulations, and historical contexts that give rise to these divergent experiences. We conclude by identifying important gaps in the literature and discussing avenues for future research.

本文调查了最近关于历史银行危机的实证文献,定义为1980年之前发生的事件。数据收集和识别方面的进展为危机的起因和后果提供了新的见解,既可以立即发现,也可以长期发现。我们强调了文献中出现的三个主要线索:首先,金融体系中的杠杆是危机的系统性前兆;第二,危机对实体经济有相当大的负面影响;第三,政府干预可以改善这些影响。历史事件的对比揭示了危机的形成和演变过程在时空上的显著差异。因此,我们还强调了产生这些不同经验的具体制度、法规和历史背景。最后,我们确定了文献中的重要空白,并讨论了未来研究的途径。《金融经济学年度评论》第15卷的最终在线出版日期预计为2023年11月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

Inflation-Adjusted Bonds, Swaps, and Derivatives 通货膨胀调整后的债券、掉期和衍生品

The purpose of this article is to review the literature on inflation-adjusted bonds, swaps, and derivatives. The methodology for valuation and risk management of these securities is an application of the foreign currency extension of a standard HJM term structure model. The two “currencies” in the extended model are real and nominal prices. Currently, for their use in monetary policy, the empirical literature primarily uses these models to estimate both the expected inflation rate and the inflation risk premium. A literature investigating the efficiency of the inflation derivative markets and a comparison of the relevant valuation models is almost nonexistent and a fruitful area for future research.

Fiscal Capacity: An Asset Pricing Perspective 财政能力:资产定价视角

This review revisits the literature on fiscal capacity using modern tools from asset pricing. We find that properly accounting for aggregate risk substantially reduces fiscal capacity. In this environment, the gap between the risk-free rate and the expected growth rate is not a sufficient statistic for fiscal capacity. To borrow at the risk-free rate when aggregate growth is risky, governments need to ask taxpayers to insure bondholders against aggregate risk, but governments in advanced economies tend to insure taxpayers against aggregate risk. We use this asset pricing perspective to review alternative mechanisms to boost fiscal capacity that have been explored in the literature.

这篇综述使用资产定价的现代工具重新审视了有关财政能力的文献。我们发现,对总风险进行适当核算会大大降低财政能力。在这种环境下,无风险利率与预期增长率之间的差距并不能充分统计财政能力。当总增长有风险时,要以无风险利率借款,政府需要要求纳税人为债券持有人投保总风险,但发达经济体的政府倾向于为纳税人投保总风险。我们利用这一资产定价视角来审查文献中探讨的提高财政能力的替代机制。《金融经济学年度评论》第15卷预计最终在线出版日期为2023年11月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

Short-Term Rate Benchmarks: The Post-LIBOR Regime 短期利率基准:后libor制度

The London Interbank Offered Rate (LIBOR), the predominant family of global short-term rate benchmarks for the past 40 years, ceased to exist in June 2023. Given the low volumes of interbank loans on which LIBOR had been based, the revelations that LIBOR had been manipulated, and the risks that countless LIBOR-dependent financial instruments without fallback rates would be cast into limbo, regulators over the last decade pushed to replace LIBOR with risk-free overnight rate benchmarks. In the United States, the new benchmark, Secured Overnight Financing Rate (SOFR), is an overnight rate based on US Treasury repo transactions: Use of term rates and derivatives on term rates is limited, and use of credit-sensitive term rates is discouraged. This article recounts the rise and fall of LIBOR; reviews the academic literature on the efficiency benefits of benchmarks, the LIBOR scandal, and the pros and cons of risk-free versus credit-sensitive rate benchmarks; and calls for further academic work on the current policy of entrenching a single-benchmark SOFR regime relative to the alternative of encouraging a two- or multi-benchmark regime of SOFR and one or more credit-sensitive term rates. Expected final online publication date for the Annual Review of Financial Economics, Volume 15 is November 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
伦敦银行同业拆借利率(LIBOR)是过去40年来全球主要的短期利率基准,于2023年6月不复存在。考虑到LIBOR所依据的银行间贷款规模很小,LIBOR被操纵的事实被揭露,以及无数依赖LIBOR的金融工具在没有备用利率的情况下陷入困境的风险,监管机构在过去十年中推动用无风险的隔夜基准利率取代LIBOR。在美国,新的基准担保隔夜融资利率(SOFR)是基于美国国债回购交易的隔夜利率:定期利率和定期利率衍生品的使用受到限制,不鼓励使用对信贷敏感的定期利率。这篇文章详述了伦敦银行间拆放款利率的涨跌;回顾了有关基准效率效益、LIBOR丑闻以及无风险与信贷敏感利率基准的利弊的学术文献;并呼吁就当前巩固单一基准SOFR制度的政策进行进一步的学术研究,而不是鼓励采用两个或多个SOFR基准制度和一个或多个信贷敏感期限利率。《金融经济学年度评论》第15卷的最终在线出版日期预计为2023年11月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

The world has been confronted in recent decades with several infectious disease outbreaks caused by novel pathogens, with the COVID-19 pandemic being the most severe of these. In this article, I review some of the main elements of epidemiological models used to forecast the trajectory of a new epidemic and to guide public health policy responses to a new infectious disease. I argue that economists have a lot to contribute to the discussion of public health policies, particularly in regard to assessing the costs and benefits of alternative policies and in improving the modeling of changes in human behavior in response to new infectious diseases. This survey is intended to serve economists interested in starting research in these areas. Expected final online publication date for the Annual Review of Financial Economics, Volume 15 is November 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
近几十年来,世界面临着几次由新型病原体引起的传染病疫情,其中新冠肺炎疫情是最严重的。在这篇文章中,我回顾了流行病学模型的一些主要元素,这些模型用于预测新的流行病的轨迹,并指导公共卫生政策应对新的传染病。我认为,经济学家对公共卫生政策的讨论有很大贡献,特别是在评估替代政策的成本和收益以及改进应对新传染病的人类行为变化模型方面。这项调查旨在为有兴趣在这些领域开展研究的经济学家提供服务。《金融经济学年度评论》第15卷预计最终在线出版日期为2023年11月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

Trends in State and Local Pension Funds 国家和地方养老基金的趋势

Unfunded public pension obligations represent the largest liability for state and local governments in the United States. As of fiscal year 2021, the total reported unfunded liabilities of these plans is $1.076 trillion. In contrast, the market value of the unfunded liability is approximately $6.501 trillion. As a result, the reported funding ratio of 82.5% falls to 43.8% under a market-based valuation. The market values reflect the fact that accrued pension promises are a form of government debt with strong statutory and contractual rights. The assumed discount rates are based on expected returns and remain elevated relative to risk-free rates, despite a decline since 2014. As a result, not only is the unfunded pension liability understated, but the yearly pension cost for newly accruing liabilities is also understated. In order to achieve high returns, pension funds have accumulated large exposure to risky assets, in particular alternative investments, which results in highly uncertain investment returns. Expected final online publication date for the Annual Review of Financial Economics, Volume 15 is November 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
没有资金的公共养老金义务是美国州和地方政府的最大负债。截至2021财年,这些计划报告的无资金负债总额为1.076万亿美元。相比之下,无资金负债的市场价值约为6.501万亿美元。因此,在基于市场的估值下,报告的82.5%的资金比率降至43.8%。市场价值反映了这样一个事实,即应计养老金承诺是一种具有强大法定和合同权利的政府债务。假设的贴现率基于预期回报,相对于无风险利率仍然较高,尽管自2014年以来有所下降。因此,不仅没有资金的养老金负债被低估了,而且新累积负债的年度养老金成本也被低估了。为了实现高回报,养老基金积累了大量风险资产,特别是另类投资,这导致了高度不确定的投资回报。《金融经济学年度评论》第15卷预计最终在线出版日期为2023年11月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。
