We consider a risk model with two independent classes of insurace risks. We assume that the two independent claim counting processes are, respectively, Poisson and Sparre Andersen processes with generalized Erlang claim inter-arrival times. The Laplace transform of the non-ruin probability is derived from a system of integro-differential equations.

There is a growing interest in the use of the tail conditional expectation as a measure of risk. For an institution faced with a random loss, the tail conditional expectation represents the conditional average amount of loss that can be incurred in a fixed period, given that the loss exceeds a specified value. This value is typically based on the quantile of the loss distribution, the so-called value-at-risk.

In this paper we study the ruin probability at a given time for liabilities of diffusion type, driven by fractional Brownian motion with Hurst exponent in the range (0.5, 1). Using fractional Itô calculus we derive a partial differential equation the solution of which provides the ruin probability.

This article is reasoning why risk and capital management in insurance companies malfunctioned partially during the recent capital market crises and what measures insurers and regulators have to adopt to ameliorate thoroughly their control and steering systems.

The development of an international standard for the accounting of insurance contracts is a challenging project. The goal of this standard is to accomplish high transparency and decision usefulness for participants in the capital markets. The paper gives an overview on the actual development status of this accounting standard for insurance contracts.

In 1998, rate regulation in the Japanese auto insurance industry shifted from a tightly controlled tariff regime to that of a less regulated (theoretically) prior approval system. While actual rate regulation is generally not directly observable, Danzon (1983) contends that the "true" character of regulation is indirectly observable in the pricing strategies of insurers.

In this paper we present an approach to market based evaluatio, of life insurance policies, in the spirit of the NUMAT proposed by Hans Bühlmann (2002) in an editorial in the ASTIN bulletin.

Asset and liability management (ALM) is extremely important for the management of financial institutions. Institutional investors typically have medium to long-term liabilities (e.g. pensions are times for future retirement), and the duration and return of assets held will have to match these. This exercise typically involves the use of projection models and assumptions.
Climate change (CC) has an impact on world climate today.

A general framework for a Bonus–Malus system (BMS) based on the number and the size of the claims is presented, the set of the bonus classes being an interval [a,?b], say 01

Fair valuation is becoming a major concern for actuaries, especially in the perspective of IAS norms. One of the key aspects in this context is the simultaneous analysis of assets and liabilities in any sound actuarial valuation. The aim of this paper is to illustrate these concepts, by comparing three common ways of givig bonus in life insurance with profit: reversionary, cash or terminal.

This paper focuses on the relevance of the insurance sector for the overall stability of the financial system by outlining the sources of risk and vulnerability facing the industry. The growing interlinkage between insurers and banks is analysed. The paper concludes by identifying some key challenges for the insurance sector.

A convolution representation is derived for the equilibrium or integrated tail distribution associated with a compound distribution. This result allows for the derivation of reliability properties of compound distributions, as well as an explicit analytic representation for the stop-loss premium, of interest in connection with insurance claims modelling.

Mixed Poisson distributions are widely used in various disciplines including actuarial applications. The family of mixed Poisson distributions contains several members according to the choice of the mixing distribution for the parameter of the Poisson distribution. Very few of them have been studied in depth, mainly because of algebraic intractability.

One of the most significant economic developments of the past decade has been the convergence of the previously separate segments of the financial services industry - particularly the banking and insurance sectors. Convergence has been driven by increasing globalization of the financial services sector, the deregulation of financial markets, and advances in computer and modelling technologies.

The classical evaluation of pure premiums for excess of loss reinsurance with reinstatements requires the knowledge of the claim size distribution of the insurance risk.

This paper deals with market exit issues in the insurance industry. It examines theoretical and practical aspects of exit regulation in insurance as well as internal and external factors that firms may use to select a market exit strategy. From comparing regulatory stringency and permitted forms of market exit in selected countries in Asia, Europe, and North America, the authors find several commonalities.

Bonus-malus systems typically lead to high maluses when claims at fault are reported. Such penalties are often difficult to implement in prctice. It is shown in this paper that this drawback may be avoided by combining a posteriori premium corrections with a deductible varying according to the level occupied in the scale.

For the classical credibility regression model the dependence structure of the error terms is specialized to an autoregressive one. The corresponding, specialized credibility formula is given and an adequate structure parameter estimation method is described.

In order to estimate the ultimate loss in long tail business, there is an increasing trend to separate the claims development triangles into individual triangles for basic and large losses and evaluate each of the chain-ladder-projections separately.

This work is based on the considerations and results in Merz (2005). Starting from the continuous analogon of the generalized Hachmeister model in Mangold (1987) and Merz (2004), the work concentrates on four models, which are derived as special cases.

The subject of this work is the development of a credibility theory in continuous time. A short introduction is followed by the stochastic modelling of the adequate premium calculation in continuous time. The terms known from the discrete theory will be transferred to a continuous time setting.

This paper asks whether the transfer of risk from banking to non-banking institutions, such as insurers, has reduced risk for the financial system as a whole or merely shifted it to less transparent sectors. If the latter is the case, then it may be that new forms of risk and vulnerability are being introduced into the global financial system.
