An analysis of the carrying capacity and life process risks of UK and Turkish insurance intermediaries

The primary aim of this paper is to examine the strategic risks associated with environmental selection and how this affects the life process risks of insurance intermediaries. To achieve this aim; firstly the carrying capacity of UK and Turkish insurance intermediaries is calculated and, secondly, the demographic, ecological and environmental variables that affect that carrying capacity are examined. Our study provides two contributions to the literature. For the first time, carrying capacity analysis is applied for an organisational community. As much as previous studies assume the existence of carrying capacity as theoretical, it has not been previously calculated on a quantitative basis. The second contribution is related to risk and insurance literature, specifically the life process risks of insurance intermediaries. The main rationale behind that analysis is the construction of a map that will simplify the strategic risk and reward decisions of insurers as to which areas are potentially profitable, or are indicative of fruitful relationships with intermediaries. Additionally, this research enables us to identify the areas that have potential for development in terms of insurance. For this reason, uncertainties relating to the selection of authorised brokers/agents as a strategic risk is, perhaps, minimised. Moreover, we have examined whether probable variables that can affect carrying capacity have contextual differences or not. The findings exhibit that there is contextual differentiations concerning the variables that affect the carrying capacity of both countries.     

Martingales in life insurance

Abstract

This paper presents a general probabilistic model, including stochastic discounting, for life insurance contracts, either a single policy or a portfolio of policies. In § 4 we define prospective reserves and annual losses in terms of our model and we show that these are generalisations of the corresponding concepts in conventional life insurance mathematics. Our main results are in § 5 where we use the martingale property of the loss process to derive upper bounds for the probability of ruin for the portfolio. These results are illustrated by two numerical examples in § 6.     

Feature selection methods involving support vector machines for prediction of insolvency in non‐life insurance companies

We propose two novel approaches for feature selection and ranking tasks based on simulated annealing (SA) and Walsh analysis, which use a support vector machine as an underlying classifier. These approaches are inspired by one of the key problems in the insurance sector: predicting the insolvency of a non‐life insurance company. This prediction is based on accounting ratios, which measure the health of the companies. The approaches proposed provide a set of ratios (the SA approach) and a ranking of the ratios (the Walsh analysis ranking) that would allow a decision about the financial state of each company studied. The proposed feature selection methods are applied to the prediction the insolvency of several Spanish non‐life insurance companies, yielding state‐of‐the‐art results in the tests performed.

Redistributive taxation and social insurance under adverse selection in the insurance market

This paper extends the analysis of optimal income taxation under uncertainty studied by Cremer and Pestieau (International Tax and Public Finance, 3, 281–295, 1996). We introduce asymmetric information in the insurance market whereby private insurance companies cannot identify the risk probability of the agents, and we examine its effect on public policy. We consider the separating equilibrium of Rothschild and Stiglitz (Quarterly Journal of Economics, 90, 629–649, 1976) and Riley (Econometrica, 47, 331–359, 1979) where the low risk agent is only partially insured. The presence of the distortion in the insurance market changes the affinity of labor, and in some cases, we show that the scope of redistribution and the resulting social welfare are higher under asymmetric information than under full information. We also show that the increase in social insurance affects the utility and labor incentive of the low risk type by relaxing the self-selection constraint in the insurance market. The policy implications of the redistributive taxation and social insurance are analytically and numerically examined.      

保险市场逆向选择与顺向选择共存研究

Uniqueness of the fair premium for equity-linked life insurance contracts

An equity-linked life insurance contract combines an endowment life insurance and an investment strategy with a minimum guarantee. The benefit of this contract is determined by the guaranteed amount plus a bonus equal to a call on the portfolio. This bonus is similar to an Asian option. This article analyzes the relationship between the periodic insurance premium and its proportional share invested into the portfolio. For a general model of the financial risks we show the existence and uniqueness of an insurance premium. Furthermore the premium is strictly increasing and convex as a function of the share invested.

Interplay of insurance and financial risks in a stochastic environment

Consider an insurer who makes risky investments and hence faces both insurance and financial risks. The insurance business is described by a discrete-time risk model modulated by a stochastic environment that poses systemic and systematic impacts on both the insurance and financial markets. This paper endeavors to quantitatively understand the interplay of the two risks in causing ruin of the insurer. Under the bivariate regular variation framework, we obtain an asymptotic formula to describe the impacts on the insurer's solvency of the two risks and of the stochastic environment.

Seasonal mortality for fractional ages in short term life insurance

Abstract

Fernández-Durán, and Gregorio-Domínguez, Seasonal Mortality for Fractional Ages in Life Insurance. Scandinavian Actuarial Journal. A uniform distribution of deaths between integral ages is a widely used assumption for estimating future-lifetimes; however, this assumption does not necessarily reflect the true distribution of deaths throughout the year. We propose the use of a seasonal mortality assumption for estimating the distribution of future-lifetimes between integral ages: this assumption accounts for the number of deaths that occurs in given months of the year, including the excess mortality that is observed in winter months. The impact of this seasonal mortality assumption on short-term life insurance premium calculations is then examined by applying the proposed assumption to Mexican mortality data.     

The evolution of the Australian life insurance industry

The life insurance industry in Australia has traditionally been an important source of long term finance for both the public and private sector. However, very little historical analysis has been undertaken into an industry that constitutes a fundamental part of the economy's financial sector. The present climate of deregulation has initiated an irrevocable process of change within the industry. To comprehend the full implications of this change it is necessary to have an understanding of how the industry has evolved. This paper seeks to provide a background account of the growth of the life insurance industry in Australia highlighting the influences that have determined the structure of the industry.     

Consolidation and efficiency in the US life insurance industry

This paper examines the relationship between mergers and acquisitions, efficiency, and scale economies in the US life insurance industry. We estimate cost and revenue efficiency over the period 1988–1995 using data envelopment analysis (DEA). The Malmquist methodology is used to measure changes in efficiency over time. We find that acquired firms achieve greater efficiency gains than firms that have not been involved in mergers or acquisitions. Firms operating with non-decreasing returns to scale (NDRS) and financially vulnerable firms are more likely to be acquisition targets. Overall, mergers and acquisitions in the life insurance industry have had a beneficial effect on efficiency.     

人寿保险精算监管系统

一、系统目标近年来,我国寿险业的迅速发展,外资寿险公司的不断进入,对寿险监管提出了更高的标准和要求。寿险经营的长期性和经营的复杂性也要求监管者要有强有力的技术手段对保险公司的经营进行监督管理。保险精算技术是寿险公司运营的重要基础,也是寿险监管的重要技术手段。而目前国际上通行的以保险公司偿付能力为核心的监管方式更离不开精算技术。我国目前寿险监管已建立了对保险公司偿付能力监管的制度,颁布和实施了一系列法规、制度。而在监管技术手段上却远远落后于监管制度建设,使得寿险监管手段和监管效率落后于寿险业的快速发展。…
