This paper develops a simple method for quantifying banks’ exposures to large (negative) shocks in a forward-looking manner. The method is based on estimating banks’ share prices sensitivities to (market) put options and does not require the actual observation of tail risk events. We find that estimated (excess) tail risk exposures for U.S. Bank Holding Companies are negatively correlated with their share price beta, suggesting that banks which appear safer in normal periods are actually more crisis prone than their beta would suggest. We also study the determinants of banks’ tail risk exposures and find that their key drivers are uninsured deposits and non-traditional activities that leave assets on banks’ balance sheets. 相似文献

European and national policies are aimed at reducing greenhouse gases and increasing energy efficiency—also in the household
sector. For this purpose, new solutions for private homes based on information and communication technologies (ICT) are being
developed and tested. However, up to now, hardly anyone has seen, experienced or lived in an environment that offers the full
range of ICT-based energy management solutions. In this study, consumer reactions to a fully furnished and equipped smart
home are analysed using focus groups (four groups with a total of 29 participants). The analysis looks at consumer perceptions
of and reactions to an energy management system which optimizes electricity consumption based on different ICT solutions.
The topics that were demonstrated in practice and then discussed with the participants included variable tariffs, smart metering,
smart appliances, and home automation. In general, there were positive group reactions to the smart home environment. Consumers
saw many advantages for themselves; especially the chance to save money. However, giving up high levels of flexibility and
adapting everyday routines to fit in with electricity tariffs were regarded as difficult. Smart appliances and smart meters
were therefore considered to be necessary elements by most participants. Concerns regarding data privacy played a major role
in one of the groups. 相似文献

The Handelsblatt Rankings 2.0: Research Rankings for the Economics Profession in Austria,Germany, and Switzerland

The distinguishing feature of all Handelsblatt rankings published over the last ten years is that they could draw on premium quality bibliometric data. We present here the new method used by KOF and DICE to compile the 2017 Handelsblatt Rankings of university departments and individual economists. As in previous years, the rankings are based on quality weighted journal publications. We show that the benchmark results are robust to various changes in the employed method, in particular to changes in the convexity of the journal quality weighting scheme. In conclusion, we show how the collected data can be used to provide customized evaluations of entire academic careers of individual economists. 相似文献

Recent changes in energy economic frameworks conditions lead to new requirements for energy systems models. Particularly in Germany, structural and locational changes in the power plant sector can be observed. Above all, this is due to the liberalisation process entailing the legal unbundling of system operators and generation companies as well as to the ambitious aims for the extension of wind energy. Consequently, modelling energy systems as single node systems, in which network constraints are neglected, can lead to suboptimal results. Most energy systems models offer the possibility to limit interregional energy exchange capacities. However, these so-called transhipment models normally neglect the actual load flows. Yet, there are several possibilities to adequately consider the characteristics of power transmission. In this paper, the most popular approaches, which are used in particular technical applications, such as the AC- (Alternating Current), the DC- (Direct Current) and the PTDF- (Power Transfer Distribution Factors) approach are introduced and discussed with respect to their application in energy systems models. In addition, first experiences with their implementations are presented. 相似文献

Interdependencies among land use systems resemble a complex network connected through demand–supply relationships. Disruption of this network may catalyse systemic risks affecting food, energy, water and environmental security (FEWES) worldwide. We describe the conceptual development, expansion and practical application of a stochastic version of the Global Biosphere Management Model (GLOBIOM), used to assess competition for land use between agriculture, bioenergy and forestry at regional and global scales. In the stochastic version of the model, systemic risks of various kinds are explicitly covered and can be analysed and mitigated in all their interactions. While traditional deterministic scenario analysis produces sets of scenario‐dependent outcomes, stochastic GLOBIOM explicitly derives robust outcomes that leave the systems better‐off, independently of which scenario applies. Stochastic GLOBIOM is formulated as a stochastic optimisation model that is critical for evaluating portfolios of robust interdependent decisions: ex‐ante strategic decisions (production allocation, storage capacities) and ex‐post adaptive (demand, trading, storage control) decisions. As an example, the model is applied to the question of optimal storage facilities, as buffers for production shortfalls, to meet regional and global FEWES requirements when extreme events occur. Expected shortfalls and storage capacities have a close relationship with Value‐at‐Risk (VaR) and Conditional Value‐at‐Risk (CVaR) risk measures. A Value of Stochastic Solutions is calculated to illustrate the benefits of the stochastic over the deterministic model approach. 相似文献

The role of women as homeowners and heads of households are changing the dynamics in which women engage in do‐it‐yourself (DIY) behavior. Because there is limited extant theory associated with female involvement in DIY behavior, a qualitative study using in‐depth interviews was conducted. Through grounded theory analysis several themes emerged during the coding process, and the themes of empowerment were especially relevant to the informants in this study. Five dimensions of empowerment were identified: empowerment through project initiation, production mastery, adding economic value to goods and services, unleashing creative potential, and empowerment through ownership. The findings show women's involvement in DIY behavior and the consumption of DIY‐related goods is closely tied to the concept of female empowerment. 相似文献
