Collective pension contracts can generate advantages for their participants by implementing forms of risk sharing. To ensure the continuity of a collective scheme, it has to be monitored whether the contracts offered to participants are financially fair in terms of their market value. When risk sharing is implemented by means of optionalities such as conditional indexation, the analysis of financial fairness is not straightforward. In this paper, we use a stylised overlapping generations model to study financial fairness for a conditional indexation scheme. We find that financial fairness for all participants at all times is not feasible within a scheme of this type, unless the nature of indexation is such that the scheme is reduced to DC. However, financial fairness for incoming generations at the moment of entry can be realised. We show how to compute the fair contribution rate as a function of the current nominal asset/liability ratio for a given level of nominal entitlements. At low levels of the ratio, the fair contribution for incoming generations is also relatively low; nevertheless, the joining of a new generation still has a positive effect on the asset/liability ratio. 相似文献

The ruling by the BGH dated 21.09.2011 (VersR 2011, 1563, Heros-II) on the consequences relating on insurance law arising from the insolvency of the Heros Group raises the question as to the decision’s implications for D&O insurance. The Fourth Civil Senate, which is the competent court for insurance law, came to the conclusion that waiving one’s right to rescission on grounds of fraudulent misrepresentation, contractually agreed upon in advance, is incompatible with the intended protection of the right to self-determination expressed in §123 BGB, and is therefore invalid. Confirming a landmark decision by the Eighth Senate dated 17.01.2007, the ruling furthermore affects the rights of insured individuals: according to the BGH they lose coverage following the insurer‘s rescission on grounds of fraudulent misrepresentation (§334 BGB) since they only acquire rights to the extent designed by the policyholder. This article offers an introduction to the issue (Sects. 1, 2) and analyses the dogmatic derivation of the invalidity of the preemptive waiver on grounds of fraudulent misrepresentation (Sects. 3–5). Finally it explores whether the insurance coverage is required by law to be maintained for bona fide persons and whether a contractual agreement is possible. 相似文献

Although mobile network operators (MNOs) carried out numerous international expansion moves over the past 25 years industry-specific empirical research on shareholder reactions to such moves and on factors explaining differences of the wealth effects of international expansion moves is scarce. Using event study methodology, the present investigation empirically captured the impacts of 148 major expansion steps into foreign mobile communication services markets announced by 29 large MNOs during the period from December 1989 to December 2004 on “abnormal” market value changes of the expanding MNO. Further, it sought to explain differences in cumulative abnormal shareholder returns related to an announcement by four characteristics of the expanding firm (e.g., foreign experience) and nine characteristics of the country targeted by an internationalization step (e.g., cultural distance; intensity of MNO regulation). 相似文献

Arguments for and against monopoly and competition in the provision of telecommunication services are considered from the perspective of a dominant telecommunications operator in a small European country, Sweden. The importance of provision of public services is stressed as well as the need for efficient international standardization. Finally, it is argued that there is a parallel between the position of dominant telecommunication operators in small and medium-sized countries and the INTELSAT system. 相似文献

In financial markets, liquidity changes randomly over time. We consider such random variations of the depth of the order book and evaluate their influence on optimal trade execution strategies. If the stochastic structure of liquidity changes satisfies certain conditions, then the unique optimal trading strategy exhibits a conventional structure with a single wait region and a single buy region, and profitable round‐trip strategies do not exist. In other cases, optimal strategies can feature multiple wait regions and optimal trade sizes that can be decreasing in the size of the position to be liquidated. Furthermore, round‐trip strategies can be profitable depending on bid–ask spread assumptions. We illustrate our findings with several examples including the Cox–Ingersoll–Ross model for the evolution of liquidity. 相似文献
