In this paper, we examine the role of usage‐based auto insurance on customers' decisions to change their insurance coverage at the renewal. Using a sample of 135,540 customers, we study whether usage‐based insurance (UBI) can facilitate the upselling and cross‐selling efforts of the firm, possibly leading to higher coverage choices and additional insurance product purchases. Our results suggest that UBI customers are more likely to change their coverage choice than non‐UBI customers at first (but not second) renewal. Both price discounts and the information provided by UBI affect the customers' coverage changes. Among UBI customers, those who get higher UBI discounts are more likely to both increase their insurance coverage (upselling) and add the comprehensive coverage option (cross‐selling), which is not directly related to driving behavior at the time of first (annual) renewal. Moreover, customers who have received more negative feedback (daily hard brakes) are more likely to increase their insurance coverage.
在本文中,我们研究了基于使用情况的汽车保险对客户在续保时决定变更保险范围的作用。我们以 135 540 位客户为样本,研究了基于使用情况的保险(UBI)是否能促进公司的追加销售和交叉销售,从而可能导致更多的保险选择和额外的保险产品购买。我们的研究结果表明,与非 UBI 客户相比,UBI 客户在首次续保(而非第二次续保)时更有可能改变其保险选择。价格折扣和 UBI 提供的信息都会影响客户的投保变化。在 UBI 客户中,获得较高 UBI 折扣的客户更有可能增加保险范围(向上销售)和增加综合保险选项(交叉销售),这与首次(年度)续保时的驾驶行为没有直接关系。此外,收到较多负面反馈(日常急刹车)的客户更有可能增加保险额度。

We develop a dynamic investment model with loan guarantees wherein insurers face information disadvantages and learn about borrower quality. Borrowers signal their qualities through investment timing, which is characterized by the investment threshold and elapsed time. We derive the conditions for separating or pooling equilibria. We show that the separating investment threshold is constant and determined mainly by the maximum threshold preventing mimicry. If project risk is higher (lower) than the market growth rate, the pooling investment threshold declines (increases) with elapsed time, and learning enhances (reduces) the willingness of high-quality borrowers to wait. Learning alleviates adverse selection and reduces guarantee costs. These effects are more pronounced with a greater uncertainty of the insurer on borrower quality. We reveal dual effects of waiting. The worse the market prospect, the higher the value of waiting in pooling outcomes. Fee-for-guarantee swaps are superior to equity-for-guarantee swaps in environments with marked information asymmetry.

我们建立了一个具有贷款担保的动态投资模型,在该模型中,保险公司面临信息劣势并了解借款人的质量。借款人通过投资时机发出其质量信号,投资时机由投资阈值和经过时间决定。我们推导出分离或集合均衡的条件。我们证明,分离投资阈值是恒定的,主要由防止模仿的最大阈值决定。如果项目风险高于(低于)市场增长率,集合投资阈值会随着时间的推移而降低(升高),学习会增强(降低)优质借款人的等待意愿。学习可以减轻逆向选择,降低担保成本。当保险公司对借款人质量的不确定性越大时,这些效应就越明显。我们揭示了等待的双重效应。市场前景越差,等待在集合结果中的价值就越高。在信息明显不对称的环境下,收费担保互换优于股权担保互换。

We theoretically investigate the equilibria and efficiencies of public and market insurance institutions within a framework where loss probabilities are interdependently influenced by the efforts of individuals and institutions (firms). We highlight the multilateral nature of interdependency, which exists within individuals, within firms, and between them. Our analysis reveals that both public and market institutions fall short of achieving first‐best efficiency, and that the relative efficiencies between the two are indeterminate, due to the externalities. Regarding effort levels, we find that under the public institution, individual efforts are lower while institutional efforts are higher compared with the social optimum and the market institution. We also find that individual and/or institutional efforts are lower under the market institution than the social optimum, with both efforts lower under severe externalities.
在损失概率受个人和机构(公司)的努力相互影响的框架下,我们从理论上研究了公共和市场保险机构的均衡和效率。我们强调相互依赖的多边性质,这种性质存在于个人内部、公司内部以及公司之间。我们的分析表明,公共机构和市场机构都无法实现第一最佳效率,而且由于外部性,两者之间的相对效率是不确定的。在努力水平方面,我们发现,与社会最优和市场体制相比,在公共体制下,个人的努力水平较低,而机构的努力水平较高。我们还发现,在市场体制下,个人和/或机构的努力低于社会最优,而在严重的外部性条件下,个人和/或机构的努力都较低。

Does inequality impede risk management? Evidence from a lab experiment in Ghana 不平等会阻碍风险管理吗?来自加纳实验室实验的证据

Low income households in agrarian developing economies face considerable livelihood risks, which have negative impacts on welfare. A growing literature focuses on internal constraints on development, which can negatively affect saving and investment behavior. Here I propose that internal constraints may also hinder risk management. Specifically, I present a theoretical model that explores how fairness preferences may create an internal constraint on risk sharing, particularly in a context of wealth inequality, and thereby also affect demand for formal insurance. To test this theory, I utilize a lab experiment, conducted in Ghana, to investigate the impact of wealth inequality on utilization of risk-management tools, interpersonal risk sharing and formal insurance, and explore how fairness preferences may mediate this effect. I find that inequality reduces risk sharing and increases demand for insurance. Moreover, I find suggestive evidence that fairness preferences create an internal constraint on risk sharing under inequality.

发展中农业经济体的低收入家庭面临着巨大的生计风险,这对其福利产生了负面影响。越来越多的文献关注发展的内部制约因素,这些因素会对储蓄和投资行为产生负面影响。在此,我提出内部制约因素也可能阻碍风险管理。具体来说,我提出了一个理论模型,探讨公平偏好如何对风险分担造成内部约束,尤其是在财富不平等的情况下,从而影响对正规保险的需求。为了验证这一理论,我利用在加纳进行的实验室实验,调查了财富不平等对风险管理工具的利用、人际风险分担和正规保险的影响,并探讨了公平偏好可能如何调解这种影响。我发现,不平等会减少风险分担,增加保险需求。此外,我还发现有暗示性证据表明,在不平等的情况下,公平偏好会对风险分担产生内部制约。
