题目：is cyber risk insurable?
摘要：
we use data on cyber losses and model the potential market equilibrium for cyber insurance to document a market failure when portfolios of cyber risk are constructed. this can be explained by the distinct properties of cyber risk, namely heavy tails, strong (tail) dependencies, high costs due to asymmetric information, and modelling risk. our results help to explain why many insurance companies are reluctant to offer cyber insurance on a broad scale. we also discuss ways to overcome the market failure. our analyses expand results from catastrophic insurance and have implications for corporate risk management and public policy.

题目：cyber risk assessment for capital management
摘要：
cyber risk is an omnipresent risk in the increasingly digitized world that is known to be difficult to manage. this paper proposes a two-pillar cyber risk management framework to address such difficulty. the first pillar, cyber risk assessment, blends the frequency-severity model in insurance with the cascade model in cybersecurity, to capture the unique feature of cyber risk. the second pillar, cyber capital management, provides informative decision-making on a well-balanced cyber risk management strategy, which includes cybersecurity investments, insurance coverage, and reserves. this framework is demonstrated by a case study based on a historical cyber incident dataset, which shows that a comprehensive cost-benefit analysis is necessary for a budget-constrained company with competing objectives to manage its cyber risk by the best possible strategy. sensitivity analysis also illustrates that the best strategy depends on various factors, such as the amount of cybersecurity investments and the effectiveness of cybersecurity controls.

题目：catastrophe model and the impact of climate change: an interdisciplinary study
摘要：
a catastrophe model widely used in the (re)insurance market offers a systematic process consisting of a stochastic model for climate events through the financial assessment of their impacts. however, it is rarely observed to discuss how climate change can be intervened in this model and what this intervention may result in. this study partially contributes to this discussion by taking into account the trend of climate change to quantify tropical cyclone (tc) risks that have been one of the major natural hazards in south korea. using historical tc records, geographical information, and socio-economic factors, we first cluster patterns of tc hazards (i.e., track, wind speed, and precipitation) affecting south korea. we then predict tc hazards and regional economic losses per cluster, and subsequently examine the temperature trend at the grid level, which we use to study the impact of climate change on loss prediction. the results highlight that the annual tc losses are expected to increase by 14 and 45% in the years 2050 and 2100, respectively, compared to that in 2020 and that the tc season in south korea may last longer in the future. our findings can be useful for (re)insurers and policymakers, who look for a next phase of catastrophe model with climate change and develop risk management schemes in regions that are more vulnerable to tc risks.

题目：insurance decisions between couples
摘要：
we investigate insurance decisions between spouses using field data from an insurtech company. empirical analyses reveal that individuals purchase significantly more insurance for their spouses than for themselves. moreover, they seem to be less responsive to their own health information compared to that of their spouses. additionally, our empirical findings indicate that the insurance gap between purchasing for oneself and purchasing for a spouse is larger when individuals perceive their spouses as less risk-averse or facing liquidity constraints. we attribute this insurance gap between spouses to motivated beliefs that individuals tend to believe they are healthier than their spouses. we test this hypothesis with a survey-based experiment and provide supporting evidence.
