Financial risk aversion and financial risk tolerance are sometimes considered to be ‘opposite sides of the same coin’, with the implication being that risk aversion (a term describing the unwillingness of an investor to take risks based on a probability assessment) and risk tolerance (an investor’s willingness to engage in a behavior based on their subjective evaluation of the uncertainty of the outcomes) are inversely-related substitutes. The purpose of this paper is to present an alternative way of viewing these constructs. We show that risk aversion and risk tolerance act as complementary factors in models designed to describe the degree of risk observed in household investment portfolios. A series of multivariate tests were used to determine that financial risk aversion is inversely related to portfolio risk, whereas financial risk tolerance is positively associated with portfolio risk. When used in the same model, the amount of explained variance in portfolio risk was increased compared to models where one, but not the other, measure was used. Overall, financial risk tolerance exhibited the largest model effect, although financial risk aversion was also important across the models analyzed in this study.
金融风险规避和金融风险容忍度有时被认为是 "一枚硬币的两面",其含义是风险规避(一个描述投资者基于概率评估不愿意承担风险的术语)和风险容忍度(投资者基于其对结果不确定性的主观评价从事某种行为的意愿)是成反比的替代品。本文旨在提出一种看待这些概念的替代方法。我们表明,在旨在描述家庭投资组合中观察到的风险程度的模型中,风险规避和风险容忍度是互补因素。通过一系列多元检验,我们确定金融风险规避与投资组合风险成反比关系,而金融风险容忍度与投资组合风险成正比关系。在同一模型中使用金融风险规避和金融风险容忍度时,投资组合风险的解释变异量与只使用一种而不使用另一种措施的模型相比有所增加。总体而言,金融风险容忍度对模型的影响最大,尽管金融风险规避在本研究分析的模型中也很重要。

This research delves into the fusion of spatial clustering and predictive modeling within auto insurance data analytics. The primary focus of this research is on addressing challenges stemming from the dynamic nature of spatial patterns in multiple accident year claim data, by using spatially constrained clustering. The spatially constrained clustering is implemented under hierarchical clustering with a soft contiguity constraint. It is highly desirable for insurance companies and insurance regulators to be able to make meaningful comparisons of loss patterns obtained from multiple reporting years that summarize multiple accident year loss metrics. By integrating spatial clustering techniques, the study not only improves the credibility of predictive models but also introduces a strategic dimension reduction method that concurrently enhances the interpretability of predictive models used. The evolving nature of spatial patterns over time poses a significant barrier to a better understanding of complex insurance systems as these patterns transform due to various factors. While spatial clustering effectively identifies regions with similar loss data characteristics, maintaining up-to-date clusters is an ongoing challenge. This research underscores the importance of studying spatial patterns of auto insurance claim data across major insurance coverage types, including Accident Benefits (AB), Collision (CL), and Third-Party Liability (TPL). The research offers regulators valuable insights into distinct risk profiles associated with different coverage categories and territories. By leveraging spatial loss data from pre-pandemic and pandemic periods, this study also aims to uncover the impact of the COVID-19 pandemic on auto insurance claims of major coverage types. From this perspective, we observe a statistically significant increase in insurance premiums for CL coverage after the pandemic. The proposed unified spatial clustering method incorporates a relabeling strategy to standardize comparisons across different accident years, contributing to a more robust understanding of the pandemic effects on auto insurance claims. This innovative approach has the potential to significantly influence data visualization and pattern recognition, thereby improving the reliability and interpretability of clustering methods.
本研究深入探讨了汽车保险数据分析中空间聚类与预测建模的融合。本研究的主要重点是通过使用空间约束聚类,解决多事故年理赔数据中空间模式的动态性质所带来的挑战。空间约束聚类是在具有软连续性约束的分层聚类下实现的。保险公司和保险监管机构非常希望能够对从多个报告年度获得的损失模式进行有意义的比较,这些损失模式总结了多个事故年度的损失指标。通过整合空间聚类技术,该研究不仅提高了预测模型的可信度,还引入了一种战略性降维方法,同时增强了预测模型的可解释性。随着时间的推移,空间模式不断演变,这对更好地理解复杂的保险系统构成了重大障碍,因为这些模式会因各种因素而发生变化。虽然空间聚类能有效识别具有相似损失数据特征的区域,但维持最新的聚类是一项持续的挑战。这项研究强调了研究主要保险类型(包括意外伤害保险 (AB)、碰撞保险 (CL) 和第三方责任保险 (TPL))的车险理赔数据空间模式的重要性。这项研究为监管机构提供了宝贵的洞察力,使其了解与不同承保类别和地区相关的独特风险概况。通过利用大流行前和大流行期间的空间损失数据,本研究还旨在揭示 COVID-19 大流行对主要承保类型的车险理赔的影响。从这个角度来看,我们观察到在大流行后,CL 保险的保费在统计上有了显著增加。所提出的统一空间聚类方法结合了重新标注策略,使不同事故年份之间的比较标准化,有助于更深入地了解大流行病对汽车保险理赔的影响。这种创新方法有可能对数据可视化和模式识别产生重大影响,从而提高聚类方法的可靠性和可解释性。

This paper investigates how the introduction of foreign exchange futures has an impact on spot volatility and considers the contemporaneous and dynamic relationship between spot volatility and foreign exchange futures trading activity, including trading volume and open interest in the Thailand Futures Exchange context, with the examples of the EUR/USD futures and USD/JPY futures. The results of the EGARCH (1,1) model show that the introduction of foreign exchange futures decreases spot volatility. It also increases the rate at which new information is impounded into spot prices but decreases the persistency of volatility shocks. A positive effect of unexpected trading volume and a negative effect of unexpected open interest on contemporaneous spot volatility are in line with the VAR(1) model results of the dynamic relationship between spot volatility and foreign exchange futures trading activity. With the impact on spot volatility caused by unexpected open interest rate being stronger than by unexpected trading volume, foreign exchange futures trading stabilizes spot volatility.
本文以欧元/美元期货和美元/日元期货为例,研究了外汇期货的引入如何对现货波动率产生影响,并考虑了现货波动率与外汇期货交易活动(包括泰国期货交易所的交易量和未平仓合约)之间的同期和动态关系。EGARCH (1,1)模型的结果显示,外汇期货的推出降低了现货波动率。它还提高了新信息在现货价格中的嵌入率,但降低了波动冲击的持续性。意外交易量和意外未平仓合约对同期现货波动率的正向影响与现货波动率和外汇期货交易活动之间动态关系的 VAR(1)模型结果一致。由于意外公开利率对即期波动率的影响强于意外交易量,外汇期货交易稳定了即期波动率。

Mean-Reverting Statistical Arbitrage Strategies in Crude Oil Markets 原油市场中的均值回复统计套利策略
IF 2.2 Q2 BUSINESS, FINANCE Pub Date : 2024-06-25 DOI: 10.3390/risks12070106
Viviana Fanelli
In this paper, we introduce the concept of statistical arbitrage through the definition of a mean-reverting trading strategy that captures persistent anomalies in long-run relationships among assets. We model the statistical arbitrage proceeding in three steps: (1) to identify mispricings in the chosen market, (2) to test mean-reverting statistical arbitrage, and (3) to develop statistical arbitrage trading strategies. We empirically investigate the existence of statistical arbitrage opportunities in crude oil markets. In particular, we focus on long-term pricing relationships between the West Texas Intermediate crude oil futures and a so-called statistical portfolio, composed by other two crude oils, Brent and Dubai. Firstly, the cointegration regression is used to track the persistent pricing equilibrium between the West Texas Intermediate crude oil price and the statistical portfolio value, and to identify mispricings between the two. Secondly, we verify that mispricing dynamics revert back to equilibrium with a predictable behaviour, and we exploit this stylized fact by applying the trading rules commonly used in equity markets to the crude oil market. The trading performance is then measured by three specific profit indicators on out-of-sample data.
在本文中,我们通过定义一种捕捉资产间长期关系中持续异常现象的均值回复交易策略,引入了统计套利的概念。我们通过三个步骤对统计套利进行建模:(1) 识别所选市场的错误定价,(2) 测试均值回复统计套利,(3) 制定统计套利交易策略。我们对原油市场是否存在统计套利机会进行了实证研究。特别是,我们重点研究了西德克萨斯中质原油期货与由其他两种原油(布伦特原油和迪拜原油)组成的所谓统计组合之间的长期定价关系。首先,我们利用协整回归来跟踪西德克萨斯中质原油价格和统计组合价值之间的持续定价均衡,并识别两者之间的错误定价。其次,我们验证了错误定价动态会以可预测的行为回到均衡状态,我们利用这一典型事实,将股票市场常用的交易规则应用于原油市场。然后,通过样本外数据的三个具体利润指标来衡量交易绩效。

The relationship between intellectual capital and firm performance represents a critical facet of corporate governance, warranting comprehensive investigation. By analyzing data from 1,151 non-financial firms listed on the Indonesia Stock Exchange over the period from 2018 to 2022, the authors utilize fixed effect regression analysis to test their hypothesis. This study’s findings reveal a positive and significant relationship between intellectual capital and firm performance. Additionally, the interaction model incorporating political connections yields statistically significant results, indicating that political connections can moderate the relationship between intellectual capital and firm performance. This study makes a substantial contribution to the literature, particularly by advancing the understanding of corporate governance through the lens of intellectual capital’s influence on firm performance. It offers both theoretical and practical insights into the Indonesian context, highlighting the moderating role of political connections. Notably, this study is the first to incorporate interaction models to assess the impact of political connections on this relationship.
智力资本与公司业绩之间的关系是公司治理的一个重要方面,值得进行全面研究。通过分析2018年至2022年期间在印度尼西亚证券交易所上市的1151家非金融企业的数据,作者利用固定效应回归分析法检验了他们的假设。研究结果表明,智力资本与企业绩效之间存在显著的正相关关系。此外,包含政治关系的交互模型也得出了统计意义上的显著结果,表明政治关系可以缓和知识资本与公司业绩之间的关系。本研究为相关文献做出了重大贡献,尤其是通过知识资本对公司业绩的影响这一视角,推进了对公司治理的理解。它为印尼的情况提供了理论和实践见解,强调了政治关系的调节作用。值得注意的是,本研究首次采用互动模型来评估政治关系对这种关系的影响。

In the insurance sector, Zero-Inflated models are commonly used due to the unique nature of insurance data, which often contain both genuine zeros (meaning no claims made) and potential claims. Although active developments in modeling excess zero data have occurred, the use of Bayesian techniques for parameter estimation in Zero-Inflated Poisson models has not been widely explored. This research aims to introduce a new Bayesian approach for estimating the parameters of the Zero-Inflated Poisson model. The method involves employing Gamma and Beta prior distributions to derive closed formulas for Bayes estimators and predictive density. Additionally, we propose a data-driven approach for selecting hyper-parameter values that produce highly accurate Bayes estimates. Simulation studies confirm that, for small and moderate sample sizes, the Bayesian method outperforms the maximum likelihood (ML) method in terms of accuracy. To illustrate the ML and Bayesian methods proposed in the article, a real dataset is analyzed.
在保险领域,由于保险数据的特殊性,通常既包含真正的零(即无赔付),也包含潜在的赔付,因此零膨胀模型很常用。尽管在超额零数据建模方面取得了积极进展,但在零膨胀泊松模型中使用贝叶斯技术进行参数估计的方法尚未得到广泛探索。本研究旨在引入一种新的贝叶斯方法来估计零膨胀泊松模型的参数。该方法采用伽马和贝塔先验分布,推导出贝叶斯估计器和预测密度的封闭公式。此外,我们还提出了一种数据驱动方法,用于选择能产生高精度贝叶斯估计值的超参数值。模拟研究证实,对于小样本量和中等样本量,贝叶斯方法的准确性优于最大似然法(ML)。为了说明文章中提出的最大似然法和贝叶斯法,我们对一个真实数据集进行了分析。

Can Multi-Peril Insurance Policies Mitigate Adverse Selection? 多重风险保单能否减轻逆向选择的影响?
IF 2.2 Q2 BUSINESS, FINANCE Pub Date : 2024-06-20 DOI: 10.3390/risks12060102
Peter Zweifel, Annette Hofmann
The objective of this paper is to pursue an intuitive idea: for a consumer who represents an “unfavorable” health risk but an “excellent risk” as a driver, a multi-peril policy could be associated with a reduced selection effort on the part of the insurer. If this intuition should be confirmed, it will serve to address the decade-long concern with risk selection both in the economic literature and on the part of policy makers. As an illustrative example, a two-peril model is developed in which consumers deploy effort in search of a policy offering them maximum coverage at the current market price while insurers deploy effort designed to stave off unfavorable risks. Two types of Nash equilibria are compared: one in which the insurer is confronted with high-risk and low-risk types, and another one where both types are a “better risk” with regard to a second peril. The difference in the insurer’s selection effort directed at high-risk and low-risk types is indeed shown to be lower in the latter case, resulting in a mitigation of adverse selection.
本文的目的是追求一种直观的想法:对于一个健康风险 "不利 "但驾驶风险 "极佳 "的消费者来说,多险种保单可能会减少保险公司的选择努力。如果这一直觉得到证实,它将有助于解决经济文献和政策制定者十年来对风险选择的担忧。举例来说,我们建立了一个双险模型,在这个模型中,消费者努力寻找以当前市场价格为其提供最大保障的保单,而保险公司则努力避免不利风险。我们对两种纳什均衡进行了比较:一种是保险人面对高风险和低风险两种类型,另一种是两种类型在第二种危险方面都是 "更好的风险"。结果表明,在后一种情况下,保险人对高风险和低风险类型的选择努力差异确实较小,从而减少了逆向选择。

The purpose of this paper was to reveal the influence of the support of the sustainable development goals (SDGs) on the financial risks of responsible universities in Russia. This paper fills the gap in the literature that exists regarding the unknown consequences of SDGs’ support by responsible Russian universities concerning their financial risks. Based on the experience of the top 30 most responsible Russian universities in 2023, we used regression analysis to compile a model for their financial risk management. This model mathematically describes the cause-and-effect relationships of financial risk management in responsible Russian universities. This paper offers a new approach to financial risk management in responsible Russian universities. In it, financial risks to Russian universities are reduced due to universities accepting responsibility for state and private investors. A feature of the new approach is that the effective use of university funds is ensured not by cost savings but by the support of the SDGs. The potential for a reduction in financial risk in responsible universities in Russia through alternative approaches to financial risk management was disclosed. The proposed new approach can potentially raise (to a large extent) the aggregate incomes of responsible universities in Russia compared to the existing approach. The main conclusion is that the existing approach to financial risk management in Russian universities is based on low-efficiency managerial measures which risk burdening universities. This burden could be prevented with the newly developed approach to financial risk management in responsible universities in Russia through support of the SDGs. The theoretical significance lies in clarifying the specific list of the SDGs whose support makes the largest contribution to reducing financial risks for the universities—namely, SDG 4, SDG 8, and SDG 9. The practical significance is that the new approach will allow for full disclosure of the potential reduction in financial risks in responsible universities in Russia in the Decade of Action (2020–2030). The managerial significance is as follows: the proposed recommendations will allow improved financial risk management in Russian universities through optimization of the support of the SDGs.
本文旨在揭示支持可持续发展目标(SDGs)对俄罗斯责任大学财务风险的影响。本文填补了有关俄罗斯责任大学支持可持续发展目标对其财务风险的未知影响的文献空白。根据 2023 年俄罗斯责任感最强的前 30 所大学的经验,我们使用回归分析法建立了一个财务风险管理模型。该模型用数学方法描述了俄罗斯责任大学财务风险管理的因果关系。本文为俄罗斯负责任大学的财务风险管理提供了一种新方法。在这种方法中,由于高校对国家和私人投资者承担责任,俄罗斯高校的财务风险得以降低。新方法的一个特点是,大学资金的有效使用不是通过节约成本而是通过支持可持续发展目标来保证的。俄罗斯负责任的大学通过财务风险管理替代方法降低财务风险的潜力得到了披露。与现有方法相比,拟议的新方法有可能(在很大程度上)提高俄罗斯责任大学的总收入。主要结论是,俄罗斯高校现有的财务风险管理方法以低效率的管理措施为基础,有可能给高校带来负担。通过支持可持续发展目标,俄罗斯责任大学新开发的财务风险管理方法可以避免这种负担。其理论意义在于明确可持续发展目标的具体清单,这些目标的支持对降低高校财务风险的贡献最大--即可持续发展目标4、可持续发展目标8和可持续发展目标9。 其实践意义在于,新方法将允许在行动十年(2020-2030年)全面披露俄罗斯责任大学财务风险的潜在降低情况。其管理意义如下:通过优化对可持续发展目标的支持,提出的建议将有助于改善俄罗斯大学的财务风险管理。

This paper fills the gap in the literature that exists regarding the unknown consequences of SDGs’ support by responsible Russian universities concerning their financial risks. Based on the experience of the top 30 most responsible Russian universities in 2023, we used regression analysis to compile a model for their financial risk management. This model mathematically describes the cause-and-effect relationships of financial risk management in responsible Russian universities. This paper offers a new approach to financial risk management in responsible Russian universities. In it, financial risks to Russian universities are reduced due to universities accepting responsibility for state and private investors. A feature of the new approach is that the effective use of university funds is ensured not by cost savings but by the support of the SDGs. The potential for a reduction in financial risk in responsible universities in Russia through alternative approaches to financial risk management was disclosed. The proposed new approach can potentially raise (to a large extent) the aggregate incomes of responsible universities in Russia compared to the existing approach. The main conclusion is that the existing approach to financial risk management in Russian universities is based on low-efficiency managerial measures which risk burdening universities. This burden could be prevented with the newly developed approach to financial risk management in responsible universities in Russia through support of the SDGs. The theoretical significance lies in clarifying the specific list of the SDGs whose support makes the largest contribution to reducing financial risks for the universities—namely, SDG 4, SDG 8, and SDG 9. The practical significance is that the new approach will allow for full disclosure of the potential reduction in financial risks in responsible universities in Russia in the Decade of Action (2020–2030).

In recent decades, the importance of transport and logistics companies has increased considerably, especially for Lithuania, where this sector is on the rise and creating benefits for various users. Therefore, this study aims to analyse the economic–financial situation of transport and logistics companies operating in Lithuania, focusing mainly on their financial risk, probability of bankruptcy, and level of solvency. To achieve these results, 416 companies were analysed based on their data from 2022. The employed methodology included descriptive analysis, quartile ratio analysis, the use of Altman’s Z-score model to predict bankruptcy, and, finally, logistic regression analysis to answer the hypotheses. The results show that the companies analysed in this study were highly profitable, with a high level of solvency and liquidity that did not compromise their continuity in the market. These results were confirmed by the Z-score analysis. In addition, it was observed that the age and size of the companies did not affect their survival on the market. This study presents results that are of great interest for the academic literature, as well as for the management of logistics companies. The originality of the study lies in its relevance and timeliness, presenting robust results for different stakeholders, such as policymakers or new entrepreneurs, among others.
近几十年来,运输和物流公司的重要性显著增加,特别是在立陶宛,该行业正在崛起,并 为各种用户创造了利益。因此,本研究旨在分析在立陶宛运营的运输和物流公司的经济财务状况,主要侧重于其财务风险、破产概率和偿付能力水平。为了得出这些结果,我们根据 416 家公司 2022 年的数据对其进行了分析。所采用的方法包括描述性分析、四分位比率分析、使用 Altman 的 Z 值模型预测破产,最后使用逻辑回归分析来回答假设。结果表明,本研究分析的公司盈利能力强,偿债能力和流动性水平高,不会影响其在市场上的持续发展。Z 值分析证实了这些结果。此外,研究还发现,公司的年龄和规模并不影响其在市场上的生存。本研究得出的结果对学术文献以及物流公司的管理都具有重要意义。这项研究的独创性在于其相关性和时效性,为不同的利益相关者,如政策制定者或新企业家等提供了可靠的结果。

This study analyzes the impact of knowledge capital (KC), a key element of firms’ innovation and competitiveness, on stock returns during economic crises when sustainable competitiveness becomes particularly important. We analyze the impact of the Global Financial Crisis and COVID-19 as economic crises, focusing on manufacturing industries with a high proportion of investment shifts from physical capital to KC. Our findings indicate that KC is positively associated with stock returns during the Global Financial Crisis and COVID-19. This positive relationship is strengthened by the firm’s ability to leverage KC, as measured by greater product market share, higher Tobin’s Q, and larger cash holdings. This study emphasizes the protective role of KC during the economic crisis when the market pays more attention to corporate sustainability and provides implications to corporate managers and investors.
本研究分析了知识资本(KC)这一企业创新和竞争力的关键要素在经济危机期间对股票回报率的影响,在经济危机期间,可持续竞争力变得尤为重要。我们分析了作为经济危机的全球金融危机和 COVID-19 的影响,重点研究了从物质资本向知识资本投资转移比例较高的制造业。我们的研究结果表明,在全球金融危机和 COVID-19 期间,KC 与股票回报率呈正相关。企业利用 KC 的能力(以更大的产品市场份额、更高的托宾 Q 值和更多的现金持有量衡量)加强了这种正相关关系。本研究强调了 KC 在市场更加关注企业可持续性的经济危机中的保护作用,并为企业管理者和投资者提供了启示。
