Along with individual corporate management and regulatory matters for instance within EU regime Solvency II, Internal Risk Models are very important for major general insurance companies. Of crucial importance in building these internal models, is the stochastic modelling of large claims and in particular, the selection and parameterization of suitable probability distributions for the amount and number of claims based on empirical data. To this end, in practice, a visually-based methodology is more appropriate and workable than strict mathematical approaches. Based on a practical case study, this paper provides some insight into a visually-based methodology for internal risk models. 相似文献

How does diversity affect performance? We develop a theoretical framework in which diversity of prevention employees (protecting the organization from harm) and of promotion employees (advancing positive outcomes) have different effects on individual and organizational performance. We use data for twenty‐eight soccer teams and 1723 players that played in 6120 games during ten seasons and find that diversity of defensive (prevention) players has a positive effect on player and team performance whereas the opposite holds for offensive (promotion) players. Joint tenure of offensive players tends to amplify these effects. 相似文献

This paper examines the effectiveness of diversity policy and interventions in the Dutch public sector and shows that business case interventions can affect employees’ commitment to their organization, contributing to staff retention rates and improving overall performance. Leadership style, as well as organizational culture, are shown to play a crucial role in the effectiveness of the interventions that were analysed. 相似文献

This paper discusses the effects of trade on long-run equilibrium values of some important economic variables of a small growing economy under alternative assumptions about the saving behavior. Using a two-commodity and two-factor model it is shown that long-run gains from trade depend not only on the saving behavior but also on the comparative advantage of the country at its autarkic steady state. 相似文献

Social media (SM) allow users to easily create, edit, or share content. The vast numbers of individuals that converge around sites like LinkedIn, Facebook, or Twitter embody a rich source of external knowledge that could be utilized for new product development (NPD). Complementing other channels for open innovation (OI), SM can provide access to novel information about customer needs and technological solutions unknown to the firm. Anecdotal evidence suggests that there are considerable benefits from using SM during an innovation project, but empirical evidence is scarce. Contributing to the perspective of openness in search, a number of hypotheses propose how SM as a new channel for OI can contribute to firm performance. This model is tested using data from the PDMA Comparative Performance Assessment Study, identifying factors influencing the relationship between SM and NPD performance. The findings indicate that utilizing information from SM channels can lead to higher performance, but that this link is influenced by the formalization of a firm's NPD process. This study also finds that the ability of a firm to benefit from external search in SM strongly depends on complementary internal processes when organizing and conducting this activity. Furthermore, managers have to take care when utilizing information from SM channels in radical projects, as for this kind of project only a weak significant performance contribution of SM could be found. 相似文献

Residential Enclosure,Power and Relationality: Rethinking Sociopolitical Relations in Southeast Asian Cities

As in many other areas around the globe, enclosed residential spaces have proliferated in Southeast Asia since the 1990s. Recent publications have presented such gated communities as ‘porous enclaves', implying multiple socio‐spatial dynamics of movements through gates and walls. However, the enclave model does not suffice for analyzing the relational dynamics generated by enclosed residential estates. The concept of ‘ecotonal space' and social geography are used to show, in the case of Cambodia's capital Phnom Penh, that the enclosure and its borders are producers and products of multiple social, spatial, economic and political relations, both symbolic and material. Property developers assert their position as an emerging elite in the city's society and politics, a process based on different types of everyday relations they have with the inhabitants of their residential estates and territorial institutions. The enclosed residential estate can serve as a resource for deploying new power relations. Consubstantial with the neopatrimonial nature of the Cambodian economy and politics, this process is a response to the opacity and uncertainty of real estate markets and urban development. 相似文献
