期刊介紹：

《Journal of Risk and Insurance》為季刊，每年4期，每期發(fā)表文章8-10篇左右。2024年影響因子為2.1，是風(fēng)險管理與保險領(lǐng)域的頂級權(quán)威學(xué)術(shù)期刊。該期刊主要發(fā)表保險經(jīng)濟(jì)學(xué)和風(fēng)險管理主題的理論和實(shí)證方面的學(xué)術(shù)論文，可以為保險市場的實(shí)踐、決策和監(jiān)管以及企業(yè)和家庭風(fēng)險管理提供重要的信息。

本期看點(diǎn)：

退休安排：

●長期收入風(fēng)險：考慮長期收入風(fēng)險會改變風(fēng)險資產(chǎn)的最優(yōu)配置以及退休的時間，退休財富與所選擇的退休年齡之間具有正向聯(lián)系。

●老年階段的金融遺憾：結(jié)果顯示，許多老年人后悔未購買壽命保障或長期護(hù)理保險，以及過早退休并領(lǐng)取社會保障金，這種情況在女性、黑人群體以及相對不富裕的老年人中尤為突出。

●退休的年金、健康險、長期護(hù)理保險需求：研究結(jié)果顯示，公共養(yǎng)老金水平較低的退休者應(yīng)將至少30%的退休金融財富配置于壽險年金；養(yǎng)老金處于平均水平的退休者應(yīng)將至少30%配置于重大疾病保險；而在不同經(jīng)濟(jì)狀況下，對長期護(hù)理（LTC）保險的配置比例在5%至33%之間不等。

年金與養(yǎng)老金計劃：

●固定收益型養(yǎng)老金計劃：從資金充足轉(zhuǎn)為資金不足的固定收益（DB）養(yǎng)老金計劃往往通過提高預(yù)期收益率（ER）來做出減少費(fèi)用的假設(shè)。

●目標(biāo)日期注冊指數(shù)掛鉤年金是退休計劃的有益補(bǔ)充，并有潛力成為與目標(biāo)日期基金相競爭的投資選擇。

長期護(hù)理保險：

●利用住房財富為長期護(hù)理（LTC）保險融資有兩種新機(jī)制：反向抵押貸款和住房回售。當(dāng)受訪者可使用儲蓄和反向抵押貸款時，他們將15.7%的總財富用于購買LTC保險；當(dāng)可使用儲蓄和住房回售時為12.8%；而僅能使用儲蓄時則僅為5.2%。

摘要：We examine an optimal portfolio problem where an individual receives nontraded labor income and must decide how to allocate her wealth between a stock and a risk-free asset, while also determining the optimal time to retire. Specifically, we explore how incorporating long-run income risk by assuming that labor income and stock prices are cointegrated affects both the optimal asset allocation and retirement strategy. Our findings show that accounting for long-run income risk alters the optimal allocation to risky assets and the timing of retirement. This helps explain why younger individuals with limited wealth are less likely to participate in the stock market, whereas wealthier individuals tend to allocate more to risky assets. Moreover, our findings reveal a positive relationship between stock investment and retirement age, driven by the positive correlation between wealth at retirement and the chosen retirement age.

本文研究了一個最優(yōu)投資組合問題：個體在獲得不可交易的勞動收入的同時，需要決定如何在股票與無風(fēng)險資產(chǎn)之間配置其財富，并確定最優(yōu)退休時點(diǎn)。具體而言，我們探討了在假設(shè)勞動收入與股票價格協(xié)整的情況下引入長期收入風(fēng)險，如何影響最優(yōu)資產(chǎn)配置與退休策略。研究結(jié)果表明，考慮長期收入風(fēng)險會改變風(fēng)險資產(chǎn)的最優(yōu)配置以及退休的時間。這一發(fā)現(xiàn)有助于解釋為何財富有限的年輕人較少參與股票市場，而較富裕的個體更傾向于將更多財富投入風(fēng)險資產(chǎn)。此外，我們的結(jié)果揭示了股票投資與退休年齡之間的正相關(guān)關(guān)系，這種關(guān)系源于退休財富與所選擇的退休年齡之間的正向聯(lián)系。

Pension underfunding and the expected return on pension assets: The impact of the 2008 financial crisis

養(yǎng)老金資金不足與養(yǎng)老金資產(chǎn)的預(yù)期收益率：2008年金融危機(jī)的影響

摘要：We use the 2008 crisis as an exogenous shock to the pension funding status of U.S. corporate defined benefit (DB) pension plans to examine its impact on the assumption of the expected return on pension assets (ER). Contrary to prior literature, we find that DB pension plans transitioning from funded to underfunded status make expense-reducing assumptions by increasing their ER. We also document that the ER manipulation is larger for plans whose funding after 2008 drops significantly. The funding deterioration conservatively generates a 28–79 basis points increase in ER, reducing the pension accounting expense by about 5.23%–14.76% ($3.49 to $9.85 million). Our results are robust to controlling for the shock induced by the global financial crisis on corporate performance and other potential channels affecting ER.

本文將2008年金融危機(jī)作為對美國企業(yè)固定收益（DB）養(yǎng)老金計劃資金狀況的外生沖擊，研究其對養(yǎng)老金資產(chǎn)預(yù)期收益率（ER）假設(shè)的影響。與既有文獻(xiàn)相反，我們發(fā)現(xiàn)，從資金充足轉(zhuǎn)為資金不足的DB養(yǎng)老金計劃往往通過提高ER來做出減少費(fèi)用的假設(shè)。進(jìn)一步分析表明，那些在2008年后資金狀況顯著惡化的計劃，其ER操縱幅度更大。資金惡化保守估計會導(dǎo)致ER上升28–79個基點(diǎn)，從而減少養(yǎng)老金會計費(fèi)用約5.23%–14.76%（即349萬至985萬美元）。我們的結(jié)論在控制全球金融危機(jī)對企業(yè)經(jīng)營表現(xiàn)的沖擊及其他可能影響ER的渠道后依然穩(wěn)健。

摘要：Many Americans remain financially underprepared for retirement. While automatic enrollment in employer-sponsored retirement plans has helped, target-date funds (TDFs) used as default investments have limitations. We propose target-date registered index-linked annuities (TD-RILAs) as a transparent, cost-effective alternative providing decreasing equity exposure over time. A theoretical analysis explores TD-RILAs' optimal structure and compares them to TDFs. A lab experiment examines investors' preferences, product transparency, default choices, and the role of information. We find that TD-RILAs are a suitable addition to retirement plans, potentially rivaling TDFs.

許多美國人在財務(wù)上仍未為退休做好充分準(zhǔn)備。盡管雇主贊助的退休計劃中的自動注冊機(jī)制有所幫助，但作為默認(rèn)投資工具的目標(biāo)日期基金（TDFs）仍存在局限性。本文提出目標(biāo)日期注冊指數(shù)掛鉤年金（TD-RILAs），作為一種透明且具成本效益的替代方案，能夠隨時間推移逐步降低股票敞口。通過理論分析，我們探討了TD-RILAs的最優(yōu)結(jié)構(gòu)，并將其與TDFs進(jìn)行比較。隨后，通過實(shí)驗(yàn)室實(shí)驗(yàn)，我們考察了投資者的偏好、產(chǎn)品透明度、默認(rèn)選擇及信息作用。研究結(jié)果表明，TD-RILAs是退休計劃的有益補(bǔ)充，并有潛力成為與TDFs相競爭的投資選擇。

摘要：This paper uses survey methods to assess the impact of access to housing wealth on long-term care (LTC) insurance demand. We compare two new mechanisms to finance LTC insurance with housing wealth: reverse mortgage loans and home reversion (partial sale and leaseback). Using data from an online survey of urban Chinese homeowners, we find that housing liquidity increases the stated demand for LTC insurance. On average, the survey participants spent 15.7% of their given total wealth to buy LTC insurance when they could use savings and a reverse mortgage, 12.8% when they could use savings and home reversion, and 5.2% when they could only use savings. Product demand was linked to economic factors, demographic variables, health, bequest motives, house price expectations, product understanding, and financial capability. Our results inform the design of new public or private sector programs that allow individuals to access their housing wealth while ‘a(chǎn)ging in place’.

本文利用問卷調(diào)查方法評估住房財富可獲取性對長期護(hù)理（LTC）保險需求的影響。我們比較了利用住房財富為LTC保險融資的兩種新機(jī)制：反向抵押貸款和住房回售（部分出售與租回）�；趯χ袊鞘蟹恐鞯脑诰�調(diào)查數(shù)據(jù)，我們發(fā)現(xiàn)住房流動性提高了受訪者的LTC保險需求。平均而言，當(dāng)受訪者可使用儲蓄和反向抵押貸款時，他們將15.7%的總財富用于購買LTC保險；當(dāng)可使用儲蓄和住房回售時為12.8%；而僅能使用儲蓄時則僅為5.2%。LTC保險的需求與經(jīng)濟(jì)因素、人口變量、健康狀況、遺產(chǎn)動機(jī)、房價預(yù)期、產(chǎn)品理解程度及金融能力密切相關(guān)。研究結(jié)果為公共或私營部門設(shè)計新計劃提供了參考，使個人能夠在“原居養(yǎng)老”的同時獲取住房財富。

摘要：To investigate financial regret among older Americans, we conduct a controlled experiment in the Health and Retirement Study. We document that many older people regret not having bought longevity protection or long-term care insurance, as well as having retired and claimed social security benefits too early. This is especially true for women, Black, and less wealthy older individuals. Additionally, we find that informing participants about objective survival probabilities boosts regret by 43% regarding not having lifetime income, and by even more for those in good health and still working.

Demand for life annuities, critical illness insurance, and long-term care insurance

壽險年金、重大疾病保險與長期護(hù)理保險的需求

摘要：We develop a rich life-cycle model to assess the demand for life annuities, critical illness insurance, and long-term care (LTC) insurance by retirees in a portfolio-allocation setting. We calibrate our model to urban China, where retirees face limited public insurance and undeveloped private markets. We show that retirees with a low public pension should allocate at least 30% of their financial wealth at retirement to a life annuity. Those with an average pension should allocate at least 30% to critical illness insurance. The allocation to LTC insurance ranges from 5% to 33% across all economic profiles considered. Access to critical illness and LTC insurance does not necessarily increase annuity demand. However, access to annuities decreases LTC insurance demand. Our results suggest that countries with limited public insurance should first ensure the adequacy of retirement income and then focus on covering catastrophic medical expenses while providing basic LTC services for all.

本文構(gòu)建了一個豐富的生命周期模型，在投資組合配置的框架下，評估退休人群對壽險年金、重大疾病保險和長期護(hù)理（LTC）保險的需求。模型以中國城市退休者為校準(zhǔn)對象，他們面臨公共保險覆蓋有限、私人市場尚不發(fā)達(dá)的情況。研究結(jié)果顯示，公共養(yǎng)老金水平較低的退休者應(yīng)將至少30%的退休金融財富配置于壽險年金；養(yǎng)老金處于平均水平的退休者應(yīng)將至少30%配置于重大疾病保險；而在不同經(jīng)濟(jì)狀況下，對LTC保險的配置比例在5%至33%之間不等。進(jìn)一步結(jié)果表明，獲得重大疾病保險與LTC保險的渠道不一定會提高對年金的需求，但獲得年金渠道則會降低對LTC保險的需求。本文的結(jié)論表明，在公共保險有限的國家，應(yīng)首先確保退休收入的充足性，然后重點(diǎn)覆蓋災(zāi)難性醫(yī)療支出，同時為所有人群提供基本的LTC服務(wù)。

Spatio-temporal risk sharing and transfer: A unified theory of multi-period decentralized insurances and annuities

時空風(fēng)險分擔(dān)與轉(zhuǎn)移：多期分散化保險與年金的統(tǒng)一理論

摘要：Two distinct strands of research focus on decentralized risk sharing plans. One strand centers on classic risk sharing and decentralized insurance, including peer-to-peer insurance, mutual aid, and DeFi insurance. The other explores decentralized annuities, such as tontine and group self-annuitization. Despite their disparate development paths, both involve decentralized risk sharing and transfer among participants. This paper aims to unify these domains by extending a theory of decentralized insurance to encompass multi-period decentralized insurances and decentralized annuities. The framework illuminates connections between spatial risk sharing and intertemporal risk transfer, and enables economic analysis of diverse scheme designs. The paper also provides a comprehensive review of various notions of temporal and spatial actuarial fairness, elucidating how different designs emerge from these distinct notions.

關(guān)于分散化風(fēng)險分擔(dān)機(jī)制的研究主要有兩個方向：一類聚焦于經(jīng)典的風(fēng)險分擔(dān)與分散化保險形式，包括點(diǎn)對點(diǎn)保險、互助以及去中心化金融（DeFi）保險；另一類則探討分散化年金，如唐提式年金（tontine）和群體自我年金化。盡管二者發(fā)展路徑不同，但均涉及參與者之間的分散化風(fēng)險分擔(dān)與轉(zhuǎn)移。本文的目標(biāo)是通過擴(kuò)展分散化保險理論，將其統(tǒng)一至多期分散化保險與分散化年金的框架中。該理論框架揭示了空間風(fēng)險分擔(dān)與跨期風(fēng)險轉(zhuǎn)移之間的聯(lián)系，并為多樣化方案的經(jīng)濟(jì)分析提供基礎(chǔ)。文章還全面回顧了不同的時間與空間精算公平性概念，闡釋了不同設(shè)計如何源自這些不同的公平性觀念。

Shared exposures or management fashions? Antecedents of convergence in the insurance and banking industries

共同風(fēng)險暴露還是管理時尚？保險業(yè)與銀行業(yè)趨同的前因

摘要：We study convergence in the attention of decision-makers across the insurance and banking industries. Our analysis is based on textual risk disclosures (10-K reports, 2006–2018), providing a snapshot of corporate priorities and contexts. We theoretically link convergence with decision-making contexts via the Attention-Based View. Leveraging strategic management theory, we identify antecedents of convergence in attention and, therefore, potentially, risk contagion. These include common trends in the macro-environment, substitution threats, and management fashions. We combine this theoretical framework with machine learning tools to create quantitative measures of convergence in attention and its antecedents. We find that the proposed measure of convergence is predictive of inter- and intra-industry stock correlations. Finally, based on regression and sensitivity analyses, we identify the relative importance of different antecedents, showing that shared risk management fashions largely drive Inter-industry convergence in attention. This highlights challenges when interpreting regulatory text data in the context of predicting contagion risk.

本文研究了保險業(yè)與銀行業(yè)決策者關(guān)注點(diǎn)的趨同現(xiàn)象。研究基于2006年至2018年的文本化風(fēng)險披露（10-K報告），提供了企業(yè)優(yōu)先事項(xiàng)與環(huán)境背景的快照。我們在理論上通過“基于注意力的視角”（Attention-Based View）將趨同與決策情境聯(lián)系起來。借助戰(zhàn)略管理理論，我們識別出關(guān)注點(diǎn)趨同的前因，并由此推測潛在的風(fēng)險傳染。這些前因包括宏觀環(huán)境的共同趨勢、替代性威脅以及管理時尚。我們將該理論框架與機(jī)器學(xué)習(xí)工具結(jié)合，提出了衡量關(guān)注點(diǎn)趨同及其前因的量化指標(biāo)。研究發(fā)現(xiàn)，該趨同指標(biāo)能夠預(yù)測跨行業(yè)與行業(yè)內(nèi)部的股票相關(guān)性。最后，通過回歸與敏感性分析，我們評估了不同前因的重要性，結(jié)果表明，共享的風(fēng)險管理時尚在很大程度上驅(qū)動了跨行業(yè)的關(guān)注點(diǎn)趨同。這一發(fā)現(xiàn)突顯了在預(yù)測傳染風(fēng)險的背景下解讀監(jiān)管文本數(shù)據(jù)所面臨的挑戰(zhàn)。
