Controlling der fakultativen Rückversicherung — in einem international tätigen professionellen Rückversicherungsunternehmen

During the last years the need for a high sophisticated ControllingConcept in respect of the international facultative reinsurance business has grown substantially. Facultative business is becoming more and more a strategic business unit or at least a profit centre on it’s own, which has to provide it’s contribution to the companies Return on equities. This (new) way of running international facultative reinsurance business requires a strong and powerful support from the controlling side. Controllers today are acting more as in-house Consultants servicing their clients, the management. The strategic portfolio view becomes more important and is beginning to dominate the (classic) operative controlling attitude, which can easily be taken of by modern and sophisticated IT-solutions.     

Bestimmung von Deckungsgrenzen bei nicht-proportionalen Rückversicherungsverträgen: Selbstbehalte in Abhängigkeit von Risikoeinstellungen

Risk measures and accordingly risk measurement increasingly gains in importance in economics. Over the past years risk measures were already used at credit and shareholders' equity depositations due to Basel II regulations. The article now introduces a hybrid decision modell and applies it to the reinsurance business. The modell uses a convex combination of risk measures and therewith enables the modelling of risk attitudes. First of all, by doing that, it can be shown, which risk attitude leads to the acceptance of a reinsurance contract, and secondly which deductible an insurer is prepared to undertake. Consequently it is possible to determine the risk attitudes of insurers. In turn, on knowledge of risk attitudes, it becomes possible to generate recommendations of the extent of the deductible at similar reinsurance contracts.     

Sicherungssysteme für Finanzdienstleistungsunternehmen im europäischen Vergleich – Theorieperspektive

The contribution discusses the design of guarantee schemes for financial services firms, with a focus on insurance guarantee schemes. It lists reasons that contribute to the development of guarantee schemes, especially stemming from a market failure risk. It further describes the pros and cons of ex-ante and of ex-post premium payments, and sets out arguments for and against risk based premiums of insurance guarantee schemes. The contribution also investigates whether the existence of insurance guarantee schemes might lead to a more risky insurance firm policy. Finally it examines in how far consumer protection based on insurance guarantee schemes prevents consumer protection based on market discipline that should be achieved by the third pillar of Solvency II.     

Zur Modellierung von Rückversicherungsverträgen in der dynamischen Finanzanalyse

In this paper we study the influence of Gaussian dependencies on the payoff of reinsurance contracts and the resulting effects on a non-life insurer's risk and return profile. To achieve this, we integrate different Gaussian dependencies and reinsurance contracts in a dynamic financial analysis (DFA) framework and conduct numerical tests within a simulation study. Depending on the reinsurance contract and the dependency employed, we find substantial differences in risk assessment for the ruin probability and for the expected policyholder deficit. The results have important implications for regulators and rating agencies that use these risk measures as a foundation for capital standards and ratings. Our results extend the findings of a recent working paper by Eling and Toplek (2008) with a detailed analysis of Gaussian dependencies under different reinsurance contracts.     

Prognose des Abwicklungsergebnisses mittels Chain-Ladder-Verfahren für abhängige Run-Off-Portfolios

In the present paper we analyse how the estimators from Merz u. Wüthrich (2007) could be generalised to the case of N correlated run-off triangles. The simultaneous view on N correlated subportfolios is motivated by the fact, that in practice a run-off portfolio often has to be divided in subportfolios, so that the homogeneity assumption of the claims reserving method on each subportfolio is satisfied. We derive an explicit formula for the process-variance, the estimation-error and the prediction error made by the forecast for the claims development result with the Chain-Ladder method. We illustrate the results by an example.     

Bürgerversicherung — Die Wirkung von Kopfprämien auf den Arbeitsmarkt

Capitation fees are considered to be an option for a change in funding principles for statutory health care insurance. This paper discusses several models of capitation fees either to be introduced for a part of the population or for all citizens. It analyses the impact of a change in financing health care on the labour market. Therefore microeconomic theory and a QUERU-model is applied. It also considers the issue of presently co-insured dependents.     

Deckungsbegrenzungen in Pflichtversicherungen – Die Bedeutung des § 114 VVG 2008 für Verträge über Pflichthaftpflichtversicherungen

Numerous liability insurances are mandatory in order to ensure the indemnification of potential victims. These compulsory insurances are regulated by sections 113 et seqq. of the “Versicherungsvertragsgesetz” (German insurance contract law). The new section 114 aims at protecting the victims' financial interests by specifying the necessary scope of cover of compulsory insurances.However, the statutory interpretation of section 114 provides several difficulties: For example, it prescribes concrete amounts on the hand – and contains a vague blanket clause on the other hand. This study wants to disclose these difficulties, develop specific solutions and reveal the fundamental legal interests which lie behind section 114.
