This paper asks whether rating agencies played a passive role or were an active driving force during Europe??s sovereign debt crisis. We address this by estimating relationships between sovereign debt ratings and macroeconomic and structural variables. We then use these equations to decompose actual ratings into systematic and arbitrary components that are not explained by previously observed procedures of rating agencies. Finally, we check whether systematic, as well as arbitrary, parts of credit ratings affect credit spreads. We find that both do affect credit spreads, which opens the possibility that arbitrary rating downgrades trigger processes of self-fulfilling prophecies that may drive even relatively healthy countries towards default. 相似文献

In large-scale societal crises, organizations involved in saving lives and protecting the public need to collaborate and coordinate their crisis communication to minimize damage and increase resilience. This study analyzed strategic leadership communication fostering such coordination in a network consisting of 24 members representing a variety of authorities, organizations and units established during a large forest fire in Sweden. As the crisis unfolded over a two-week period, 10 network meetings were observed and audio recorded. Discourse analysis was employed to analyze network leaders’ and members’ communication during the meetings. Findings illustrate that leadership communication strategies that fostered networked coordination of organizations’ crisis communication differ in significant ways from leadership communication in noncrisis and team contexts. Salient leadership communication strategies of directing/structuring and encouraging/facilitating were employed during crisis network meetings and functioned to coordinate involved organizations’ crisis communication efforts during time pressure. The study contributes with new knowledge of strategic leadership communication for crisis network coordination, which is important to crisis management and can be used in crisis preparation to enhance resilience. 相似文献

In this paper, models for claim frequency and average claim size in non-life insurance are considered. Both covariates and spatial random effects are included allowing the modelling of a spatial dependency pattern. We assume a Poisson model for the number of claims, while claim size is modelled using a Gamma distribution. However, in contrast to the usual compound Poisson model, we allow for dependencies between claim size and claim frequency. A fully Bayesian approach is followed, parameters are estimated using Markov Chain Monte Carlo (MCMC). The issue of model comparison is thoroughly addressed. Besides the deviance information criterion and the predictive model choice criterion, we suggest the use of proper scoring rules based on the posterior predictive distribution for comparing models. We give an application to a comprehensive data set from a German car insurance company. The inclusion of spatial effects significantly improves the models for both claim frequency and claim size, and also leads to more accurate predictions of the total claim sizes. Further, we detect significant dependencies between the number of claims and claim size. Both spatial and number of claims effects are interpreted and quantified from an actuarial point of view. 相似文献

Competing insurance intermediaries provide heterogeneous services that are difficult for incompletely informed consumers to assess. Transaction cost economics, search theory, and principal‐agent theory provide arguments on product quality differences between exclusive agents and independent intermediaries. This article uses a sample of 927 insurance intermediaries in Germany. By performing OLS estimations, we test the impact of the different distribution channels and other factors on intermediaries’ service quality. Depending on the proxies used for service quality, we find mixed evidence for the product quality hypothesis. Service quality depends to a large extent on the information‐gathering and processing activities of the individual intermediaries, independent of the respective distribution channel. 相似文献

Over the last 20 years, advanced economies have experienced an “unemployment versus inequality” tradeoff that is critically uneven across countries. To explain this, we propose an extended HOS model in which: the factors are skilled and unskilled labor; there is a continuum of goods; the world comprises two North countries (one egalitarian and one nonegalitarian) and the South; there is no factor price equalization; globalization consists in the South cornering a growing share of world production. In the North, globalization entails an inequality–unemployment tradeoff and the adjustment to globalization is more painful for the country that was initially inequality‐oriented. 相似文献

Traumatische Erfahrungen begleiten Betroffene ein Leben lang - Wird bei einer Krankenhauseinweisung oder beim Umzug in ein
Pflegeheim die Posttraumatische Belastungsst?rung nicht erkannt, kann es leicht zu Traumareaktivierungen kommen, die auch

Although pension funds have gained importance in the last two decades, their role has not been described in detail by economic models. This article focuses on the scope of these institutional investors when they are not satisfied with a management team of a company in which the pension fund holds a block of shares. Stock holdings by pension funds are largely dispersed. Therefore, any intervention by pension funds in corporate governance requires the formation of a coalition of pension funds. The realization of a coordinated intervention, in turn, is subject to the problems related to the provision of public goods, such as free riding. We find that the stock dispersion and the combined share of pension funds, coordination costs and the attractiveness of the exit option are relevant factors for determining the probability of the success of interventions. 相似文献
