保险公司偿付能力风险信息对称性与市场供求

保险公司偿付能力充足性是保险监管的内容之一,但是这一信息却往往不被投保人所获知,造成保险供给(保险公司)和保险需求(投保人)两方信息的不对称.本文以保险公司存在偿付能力风险为基本假定,以累积性预期理论和风险调整资本收益率构建保险需求和供给模型,分析在信息对称条件下和信息不对称条件下保险需求的变化及其对保险供给和保险公司...     

New standard regulations regarding allocation to the safety reserve in Sweden

Abstract

This paper describes a statistical investigation of observed loss ratios and run-offs for a number of Swedish insurance companies within different lines of business. The main aim of the investigation was to revise existing upper limits for allocation to the so-called safety reserve, which is an untaxed contingency reserve. The effort was successful in that new rules were established by the Swedish Supervisory Authority in accordance with the results of the investigation. This paper also contains an exposition of the general principles underlying the Swedish safety reserve.     

Uncertainty on survival probabilities and solvency capital requirement: application to long-term care insurance

In this paper, we focus on uncertainty issues on disabled lives survival probabilities of LTC insurance policyholders and its consequences on solvency capital requirement. Among the risks affecting long-term care portfolios, special attention is addressed to the table risk, i.e. the risk of unanticipated aggregate mortality, arising from the uncertainty in modeling LTC claimants survival law. The table risk can be thought as the risk of systematic deviations referring not only to a parameter risk but, as well, to any other sources leading to a misinterpretation of the life table resulting for example from an evolution of medical techniques or a change in rules of acceptance. In fine, the idea is to introduce the risk of systematic deviations arising from the uncertainty on the disabled lives death probabilities directly. We analyze the consequences of an error of appreciation on the disabled lives survival probabilities in terms of level of reserves and describe a framework in an Own Risk and Solvency Assessment perspective to measure the gap between the risk profile from the standard formula to the risk analysis specific to the organism.

How does issuing contingent convertible bonds improve bank's solvency? A Value-at-Risk and Expected Shortfall approach

This paper examines how issuing an innovative financial instrument called contingent convertible bond (CoCo) may enhance bank's solvency in comparison to issuing a conventional bond. CoCos convert automatically into common equity or have a principal write-down when bank's regulatory capital fails to meet a predetermined level. They have been invented and put into legislation with an objective to absorb losses thus preventing institutions from bankruptcy. From the standpoint of an issuer CoCos bring about two counter effects regarding his solvency: on one hand they recapitalize a bank approaching insolvency on the other hand CoCos pay much higher coupon comparing to conventional bonds. In our model a bank has two funding alternatives: either to issue CoCos or conventional bonds. We measure issuer's default risk using the concept of Value-at-Risk (VaR) and Expected Shortfall (ES). We conclude that CoCos have the potential to strengthen the resilience of the issuer on the condition that the probability of conversion triggering is higher than the VaR's significance level. Our findings can be helpful to the policymakers and banks to better understand the impact of CoCos on issuer's solvency.     

危机前后美国寿险公司不动产投资研究

基于ISIS全球保险公司数据库收录的美国寿险公司数据资料,本文研究了美国寿险公司的不动产投资情况.研究发现,从美国寿险公司的资产组合构成来看,不动产投资所占的比重还很低,且在次贷危机前后不动产投资在整个资产组合中所占的比重没有很大的变动.在美国房地产市场顶峰期的2005年,寿险公司所持有的不动产投资反而是最低的.但是,...

Pension plan solvency and extreme market movements: a regime switching approach

We develop and test a new approach to assess defined benefit (DB) pension plan solvency risk in the presence of extreme market movements. Our method captures both the ‘fat-tailed’ nature of asset returns and their correlation with discount rate changes. We show that the standard assumption of constant discount rates leads to dramatic underestimation of future projections of pension plan solvency risk. Failing to incorporate leptokurtosis into asset returns also leads to downward biased estimates of risk, but this is less pronounced than the time-varying discount rate effect. Further modifying the model to capture the correlation between asset returns and the discount rate provides additional improvements in the projection of future pension plan solvency. This reduces the perceived future risk of underfunding because of the negative correlation between interest rate changes and asset returns. These results have important implications for those with responsibility for balancing risk against expected return when seeking to improve the current poor funding positions of DB pension schemes.
