The amendment of the German Act on Insurance Contracts comprises a number of substantial modifications regarding liability insurance. The most important modification is the introduction of a direct claim against the insurer with regard to all compulsory insurances. Such a direct claim is up to now only known from the motor vehicle liability insurance. Yet, a direct claim will be advantageous for the aggrieved claimant only if he manages to identify the proper insurer. As a result of the structural differences to the motor vehicle liability insurance the act of identifying the insurer is almost utterly impossible for the claimant without any help by the insured. Thus the claimant must also be given a claim against the insured to be furnished with all necessary information regarding the insurer. This right originates from sec. 242 of the German Civil Code. 相似文献

In this paper we studyy arithmetic Asian options when the underlying stock is driven by special semimartingale processes. We show that the inherently path dependent problem of pricing Asian options can be transformed into a problem without path dependence in the payoff function. We also show that the price is driven by a process with independent increments, Levy processes being a special case. This approach applies for both discretely or continuously options. 相似文献

We consider the portfolio choice problem for a long‐run investor in a general continuous semimartingale model. We combine the decision criterion of pathwise growth optimality with a flexible specification of attitude toward risk, encoded by a linear drawdown constraint imposed on admissible wealth processes. We define the constrained numéraire property through the notion of expected relative return and prove that drawdown‐constrained numéraire portfolio exists and is unique, but may depend on the investment horizon. However, when sampled at the times of its maximum and asymptotically as the time‐horizon becomes distant, the drawdown‐constrained numéraire portfolio is given explicitly through a model‐independent transformation of the unconstrained numéraire portfolio. The asymptotically growth‐optimal strategy is obtained as limit of numéraire strategies on finite horizons. 相似文献

This paper develops a real option model to explain the decision of enlarging a new foreign subsidiary by subsequent investment. The model is tested on a panel of 1148 subsidiaries in 22 host countries. The findings complement the traditional process model of firm internationalization. Rather than abiding by an incremental pattern of investment, internationalizing firms seem to keep foreign investment strategies flexible and build up their subsidiaries contingent upon the interaction of economic volatility and irreversibility of investment. However, the moderating effect of irreversibility on the relationship between uncertainty and investment may not hold for downside risks such as political instability. 相似文献

The practice of providing expatriates with cross-cultural training varies widely among business corporations. To examine the proposition that some characteristics of the parent corporation context could be munificent to the practice of providing cross-cultural training, a mail survey was addressed to business expatriates in China. Surprisingly, the results showed no association between corporate size, international stake, and international experience on the one hand and the extent to which the expatriates had received cross-cultural training on the other hand. Although an ad hoc analysis found a positive relationship between international experience and the provision of sequential cross-cultural training, there was no association between any of the variables depicting corporate context and predeparture or postarrival training. The findings and their implications are discussed in detail. 相似文献

Theories of financial frictions in international capital markets suggest that financial intermediaries' balance sheet constraints amplify fundamental shocks. We present empirical evidence for such theories by decomposing the U.S. dollar risk premium into components associated with macroeconomic fundamentals, and a component associated with financial intermediary balance sheets. Relative to the benchmark model with only macroeconomic state variables, balance sheets amplify the U.S. dollar risk premium. We discuss applications to financial stability monitoring. 相似文献

Abstract. In addition to standard methods of environmental valuation, a novel approach has recently emerged which models individuals' self-rated happiness as a function of their incomes and the prevailing environmental conditions. The estimated relationship is used to calculate the trade-off people would be willing to make between income and environmental conditions, i.e. the increase in income necessary to compensate individuals for any given decline in environmental quality. While the basic idea is simple, the theoretical and empirical details may be complex, and they may vary from application to application. This paper discusses the relevant conceptual and methodological issues and reviews applications to air and water pollution, noise nuisance, climate parameters, and natural hazards. 相似文献

The German federal government’s fiscal consolidation package, announced in June, is designed to permanently reduce the federal
deficit to a new target level. This article uses a three-region version of the European Commission’s QUEST model to gauge
the impact of the package on Germany and the spillover to the rest of the euro area and the rest of the world. 相似文献

Product aesthetics is a powerful means for achieving competitive advantage. Yet most studies to date have focused on the role of aesthetics in shaping pre-purchase preferences and have failed to consider how product aesthetics affects post-purchase processes and consumers' usage behavior. This research focuses on the relationship between aesthetics and usage behavior in the context of durable products. Studies 1A to 1C provide evidence of a positive effect of product aesthetics on usage intensity using market data from the car and the fashion industries. Study 2 corroborates these findings and shows that the more intensive use of highly aesthetic products may lead to the acquisition of product-specific usage skills that form the basis for a cognitive lock-in. Hence, consumers are less likely to switch away from products with appealing designs, an effect that is labeled as the ‘aesthetic fidelity’ effect. Study 3 addresses an alternative explanation for the ‘aesthetic fidelity effect’ based on mood and motivation but finds that the ‘aesthetic fidelity’ effect is indeed determined by usage intensity. Finally, Study 4 identifies a boundary condition of the positive effect of product aesthetics on product usage, showing that it is limited to durable products. In sum, this research demonstrates that the effects of product aesthetics extend beyond the pre-consumption stage and have an enduring impact on people's consumption experiences. 相似文献
