The current trend back to municipal utilities (??remunicipalisation??) in the German energy system shows very different approaches and variants in the real cases. Converting the distribution network from privately-owned distribution companies to municipally-owned entities often forms the starting point of such restructuring processes. Ecological or regional development motivations are at the forefront of public debates. The authors emphasize the importance of energy economic aspects of this problem. Advantages and disadvantages of remunicipalisation projects depend strongly on the specific regional circumstances. Important factors are the potentials for cooperation and expansion of the business activities. Moreover, the price which has to be paid for taking over the network infrastructure has to be taken into account as the decisive parameter: The price for buying or renting the network and the possible revenues on the backdrop of incentive-based regulation define the economic viability for the municipality. Many of the often heard arguments pro remunicipalisation, such as the objective of decentralized energy supply, labour effects and municipal contributions to climate protection, do not fully convince in the end; as well the fiscal status of many municipalities in Germany is severe. Nonetheless remunicipalisation must not be rejected in general because there is no general proof for welfare losses resulting from these projects. In fact, it depends mainly on local influencing factors to what extent municipalities should be or become active in the field of energy supply. Among the most important aspects the preferences of the citizens, the environmental and political aims of the municipality (so far they are defined) and the available resources of the municipal decision making persons and bodies must be mentioned. However, in economic terms the leeway for the municipality remains restricted by the costs of operating the network and tariff regulation. 相似文献

How large is liquidity risk in an automated auction market? 总被引:2,自引:0,他引:2
We introduce a new empirical methodology that models liquidity risk over short time periods for impatient traders who submit market orders. Using Value-at-Risk type measures, we quantify the liquidity risk premia for portfolios and individual stocks traded on the automated auction market Xetra. The specificity of our approach relies on the adequate econometric modelling of the potential price impact incurred by the liquidation of a portfolio. We study the sensitivity of liquidity risk towards portfolio size and traders' time horizon, and interpret its diurnal variation in the light of market microstructure theory.

Records of all registered deaths due to injuries maintained by the Legal Medicine Department in Maputo City for the period 1 January to 31 December 2000 were reviewed. Among the 1135 registered deaths, road traffic injuries accounted for the most common underlying cause of death (43.7%), followed by firearm discharge (8.7%) and burns (7.8%). For all deaths, skull fracture (21.9%), organ system injury (17.2%) and brain tissue injury (9.3%) were the most important intermediate causes of death and among the immediate causes of death acute anaemia (21.9%) was the most common followed by asphyxia (14.4%) and traumatic shock (12.0%). Overall, most cases were seen in the age group 20-29 years (27.0%) and comprising mainly males (male/female ratio 3.1). The most commonly reported cause for the victims to sustain injuries leading to death were accidents (59.4%), followed by homicides (19.8%), unknown causes (16.1%) and suicides (4.2%). Prevention of road traffic injuries and improved emergency care and health facility-based treatment is needed to reduce injury-related mortality. 相似文献

How should we understand the relationship between urban environments and infectious diseases? This article addresses this question from three particular perspectives: that of the materialities of health, that of nature and that of networks. The first perspective analytically blends biological dynamics, environmental influence and social practice. The second perspective, mainly influenced by multispecies ethnographies, foregrounds the liveliness and unboundedness of cities. Finally, the third perspective analyses how health is drawn into the domain of security. The article argues that while globalization and urbanization are often discussed as having triggered the emergence and spread of pathogens, urban epidemics are not self‐evident and ‘natural' consequences of these pro‐cesses. They do not fall neatly into universal categories of space, modernity or risk; rather, they are produced and shaped by a range of social, political, biological and economic sites and scales. Accordingly, the emergence of pathogens depends on its articulation through specific analytical frameworks. This article suggests that a critical focus on how infectious diseases manifest themselves differently in different local contexts may not only provide insights into the manifold forms of urban life, but also into the multiple, complex and highly political constitution of health. 相似文献

We analyze the effect of worker inflows on establishments’ productivity, using German data. Previous studies for other countries have found positive effects of hiring workers from superior (more productive or higher paying) firms. Ranking establishments by their median wage, we find that inflows from inferior establishments seem to increase hiring establishments’ productivity. Further empirical analyses suggest our findings are due to a positive selection of such inflows from their sending establishments. These workers might have to find a better job match in order to advance their careers, an interpretation supported by the finding that the effect is driven by workers with short tenure at their previous employer. Our findings reflect the increasingly assortative pattern of worker mobility in Germany found in a related strand of literature. 相似文献

We consider the class of law invariant convex risk measures with robust representation rh,p(X)=supfò01 [AV@Rs(X)f(s)-fp(s)h(s)] ds\rho_{h,p}(X)=\sup_{f}\int_{0}^{1} [AV@R_{s}(X)f(s)-f^{p}(s)h(s)]\,ds, where 1≤p<∞ and h is a positive and strictly decreasing function. The supremum is taken over the set of all Radon–Nikodym derivatives corresponding
to the set of all probability measures on (0,1] which are absolutely continuous with respect to Lebesgue measure. We provide
necessary and sufficient conditions for the position X such that ρ
h,p
(X) is real-valued and the supremum is attained. Using variational methods, an explicit formula for the maximizer is given.
We exhibit two examples of such risk measures and compare them to the average value at risk. 相似文献
