On the Lack of Participating Policy Usage by Stock Insurance Companies

Stock insurers can reduce or eliminate agency conflicts between policyholders and stockholders by issuing participating insurance. Despite this benefit, most stock companies don't offer participating contracts. This study explains why. We study an equilibrium with both stock and mutual insurers in which stockholders set premiums to provide a fair expected return on their investment, and with a policyholder who chooses the insurance contract that maximizes her expected utility. We demonstrate that stockholders cannot profitably offer fully participating contracts, but can profitably offer partially participating insurance. However, when the policyholder participation fraction is high, the fair‐return premium is so large that the policyholder always prefers fully participating insurance from the mutual company. Policies with lower levels of policyholder participation are optimal for policyholders with relatively high risk aversion, though such policies are usually prohibited by insurance legislation. Thus, the reason stock insurers rarely issue participating contracts isn't because the potential benefits are small or unimportant. Rather, profitability or regulatory constraints simply prevent stock insurers from exercising those benefits in equilibrium.     

Creating Customer Value in Participating Life Insurance

The value of a life insurance contract may differ depending on whether it is looked at from the customer's point of view or that of the insurance company. We assume that the insurer is able to replicate the life insurance contract's cash flows via assets traded on the capital market and can hence apply risk‐neutral valuation techniques. The policyholder, on the other hand, will take risk preferences and diversification opportunities into account when placing a value on that same contract. Customer value is represented by policyholder willingness to pay and depends on the contract parameters, that is, the guaranteed interest rate and the annual and terminal surplus participation rate. The aim of this article is to analyze and compare these two perspectives. In particular, we identify contract parameter combinations that—while keeping the contract value fixed for the insurer—maximize customer value. In addition, we derive explicit expressions for a selection of specific cases. Our results suggest that a customer segmentation in this sense, that is, based on the different ways customers evaluate life insurance contracts and embedded investment guarantees while ensuring fair values, is worthwhile for insurance companies as doing so can result in substantial increases in policyholder willingness to pay.     

Life insurance in a contingent claim framework: Pricing and regulatory implications

In this paper we develop a contingent claim model to evaluate the equity and liabilities of a life insurance company. The limited liability of shareholders is explicitly modelled. We focus on a specific type of life insurance policy—namely, the profit-sharing policy. In this policy, the policyholder is entitled to a guaranteed interest rate and a percentage of the company's yearly financial revenues. The implicit equilibrium interest rate and profit-sharing ratio are derived and analyzed. We finally discuss regulatory measures frequently encountered in the life insurance business such as rate ceilings, capital ratios, and asset restrictions.     

关于我国利率和利率传导关系的思考

当前我国银行体系利率大致可分为货币市场利率和信贷市场利率,其中由央行指定的利率主要有存贷款基准利率、再贴现率等。在货币市场上,隔夜同业拆借利率具有基准利率的地位。在信贷市场上,在特定时期,保持适当的存贷款利差具有积极意义。由于一些阻碍信贷市场与货币市场统一的制度安排的存在,这两个市场间的利率传导呈现出一定的不对称性。为推进利率市场化,进一步完善我国利率体系,下一步应逐步弥合市场分割,加强货币市场基准利率建设,培育商业银行利率定价能力。     

资产负债指数：资产负债匹配管理框架下的保险固定收益投资绩效评价

基于利益相关者理论的投保人与保险人的博弈分析

目前我国不少保险公司把企业的短期边际利润作为唯一经营目标,保险人与投保人的利益冲突问题不容忽视。由博弈结果分析可知,投保人作为保险企业的利益相关者,其利益的保护和保险企业的长期发展息息相关。如果投保人利益长期得不到有效的保障,投保人会选择退出保险市场,这将影响到保险业的市场占有率、信誉和形象等等,给保险业的长期健康发展带来威胁。     

Optimal investment of an insurer with regime-switching and risk constraint

We investigate an optimal investment problem of an insurance company in the presence of risk constraint and regime-switching using a game theoretic approach. A dynamic risk constraint is considered where we constrain the uncertainty aversion to the ‘true’ model for financial risk at a given level. We describe the surplus of an insurance company using a general jump process, namely, a Markov-modulated random measure. The insurance company invests the surplus in a risky financial asset whose dynamics are modeled by a regime-switching geometric Brownian motion. To incorporate model uncertainty, we consider a robust approach, where a family of probability measures is cosidered and the insurance company maximizes the expected utility of terminal wealth in the ‘worst-case’ probability scenario. The optimal investment problem is then formulated as a constrained two-player, zero-sum, stochastic differential game between the insurance company and the market. Different from the other works in the literature, our technique is to transform the problem into a deterministic differential game first, in order to obtain the optimal strategy of the game problem explicitly.     

Optimal monetary policy in an economy with incomplete markets and idiosyncratic risk

This study investigates an incomplete markets economy in which the saving behavior of a continuum of infinitely lived agents is influenced by precautionary saving motives and borrowing constraints. Agents can use two types of assets (interest bearing IOUS and money) to smooth consumption. Money is valued because of a timing friction in the bond market. In particular, the bond market closes before agents observe their idiosyncratic productivity shock. I find that the Friedman rule is not optimal for this economy. The results indicate that the optimal allocation has a rate of inflation of 10%, and a positive amount of private credit held by the government. A positive inflation rate transfers resources from agents with big endowments to those holding bonds which improves risk sharing, and therefore, welfare. However, for higher rates of inflation, agents economize on money holdings, offsetting the insurance effects, and causing a reduction in welfare. Furthermore, higher rates of inflation discourage agents from borrowing, and the endogenous lower bound on bond holdings is higher than the exogenous borrowing limit. High rates of inflation, therefore, exacerbate frictions in the bond market.     

贷款基础利率运行特征与影响

贷款基础利率（LPR）的推出是我国利率市场化的重要一步。LPR运行半年来,总体呈平稳单边上行走势,波动幅度较小,但与货币市场基准利率存在一定背离。文章分析指出,存贷款利率或额度管理、货币市场与信贷市场资金流通存在障碍是LPR与货币市场利率背离的主要原因;LPR缓慢上行主要受到银行存款贷款增速下滑的影响。文章从完善LPR报价模型、推广LPR在信贷产品中的运用等方面提出进一步发挥LPR基准作用的建议。     

Feasible fraud and auditing probabilities for insurance companies and policyholders

Insurance claims fraud is counted among the major concerns in the insurance industry, the reason being that excess payments due to fraudulent claims account for a large percentage of the total payments each year. We formulate optimization problems from the insurance company as well as the policyholder perspective based on a costly state verification approach. In this setting??while the policyholder observes his losses privately??the insurance company can decide to verify the truthfulness of incoming claims at some cost. We show simulation results illustrating the agreement range which is characterized by all valid fraud and auditing probability combinations both stakeholders are willing to accept. Furthermore, we present the impact of different valid probability combinations on the insurance company??s and the policyholder??s objective quantities and analyze the sensitivity of the agreement range with respect to a relevant input parameter. This contribution summarizes the major findings of a working paper written by Müller et?al. (Working Papers on Risk Management and Insurance (IVW-HSG), No. 92, 2011).     

Determinanten des Kundenwerts von Versicherungsnehmern

This paper discusses how the customer equity concept can be transformed to fit to insurance policy holders. The finding is that the equity of a policyholder can not be calculated in line with concepts of other classes of business, because the insurance industry shows special features in its core business. The stochastic characteristics of such a business must be integrated into the concept. These include its service nature and specific supervisory regulations for the capital investments as well as the distribution of profit. In terms of the insurance company, the following equity-determiners of a policyholder are important and should be part of the customer equity model: Firstly the equity of the customer with regard to the past, his future potential and his cross-selling equity as the monetary determiners. Secondly the equity which can be generated through word-of-mouth and customer information. The remaining determiners of the concept used in other branches of business, notably the equity of synergy, cooperation and loyality of a customer are already incorporated in the mentioned components.     

票据市场利率体系及其与银行间货币市场整体利率的关系

我国的商业汇票利率体系主要由承兑费率、贴现利率、转贴现利率和再贴现利率构成。其中作为银行间市场业务的票据转贴现，其利率已实现市场化。在监管部门加大力度规范会计科目核算、严查逃避信贷规模的票据业务后，买断性日趋明显，其利率更多受到信贷规模影响，与其它银行间货币市场利率产生了一定背离；回购式转贴现业务则逐步脱离规模互转方式，近期呈现了较强的资金业务特性，利率水平逐步接轨其它银行间货币市场利率。     

Financial innovation,new assets,and the behavior of money demand

Two fundamental changes in US banking regulations have affected the behavior of money demand (M1). The first authorized checkable deposit accounts paying explicit interest rates. The second allowed these rates to be market determined. The theoretical literature does not directly address the impact of these events, suggesting that they are primarily an empirical issue. However, the empirical literature has yet to agree on the impact of financial innovation on money demand; for example, several studies report an increase in the elasticity of money demand, several others report a decline. This paper uses a Lancaster-type choice model to analyze formally the expected impact of these two changes on the demand for money. The model derives specific conditions under which (i) the demand for money increases as new assets are introduced and (ii) the impact of either the introduction of new assets or the elimination of interest rate restrictions on the elasticity of money demand.     

融资流动性与债券资产流动性的互动特征——基于MS-VAR模型的时变分析

依据2015-2021年货币市场和债券市场的时间序列数据,运用MS-VAR探究了不同违约风险环境下融资流动性与债券资产流动性间的互动关系。研究发现：无论是利率债还是信用债,其资产流动性与货币市场的融资流动性存在互为正反馈的流动性螺旋。此外,两类流动性间的互动特征存在非对称性和异质性,在风险时期,融资流动性与利率债资产流动性互动特征比较明显,而在平稳时期,融资流动性与信用债资产流动性互动特征比较明显。     

德国利率市场化改革的特点与其金融业发展

利率市场化是指金融机构在货币市场经营融资的利率由市场供求来决定,它包括利率决定、利率传导、利率结构和利率管理的市场化。文章考察了德国利率市场化改革的特点及其对金融业发展的积极影响。德国利率市场化改革分步骤平稳推进。改革后,在全能银行模式下德国金融业没有出现象美、英那样的银行集中倒闭危机;银行贷款在非金融部门融资中仍居于主导地位,而住户部门的金融资产结构发生显著变化;德国的货币政策主要是通过改变银行的流动性来影响金融市场利率,进而间接影响银行信贷政策以及实体经济。

Portfolio Insurance with Liquidity Risk

This paper studies a portfolio insurance problem with liquidity risk. We consider an investor who wants to maximize the expected growth rate of wealth in a low liquid market. The investor can trade assets only at random times and his wealth must not fall below a predetermined floor. We find the optimal expected growth rate and an optimal strategy. The optimal strategy is closely related with a traditional constant proportion portfolio insurance strategy. Also we show that the same strategy maximizes the growth rate almost surely. Further we study the floor effect on the growth rate.     

供应链应收账款融资模式引入信用保险的企业行为研究——基于前景理论的演化博弈模型

供应链应收账款融资模式是有效解决中小企业融资难的一种方法,而核心企业在供应链应收账款融资模式中作为最终的还款来源,一旦出现违约情况,代价十分高昂,由保险公司对这部分应收账款提供信用保障,将有效控制核心企业出现的信用风险。为此,架构了一个包含中小企业、核心企业、保险公司的交易演化博弈模型,基于前景理论,构造了中小企业的价值函数,通过对该模型的演化均衡过程的比较静态分析,论证了保险公司的费率水平、赔偿比例、追偿比例等因素,均会对中小企业与核心企业交易的博弈均衡产生影响。最后,根据论证结论,从保险机制发挥作用角度,就促进交易均衡的达成提出了对策。
