The implementation of smart meters in German households by 2032 is a major step in the transition towards an intelligent and connected energy system. Despite of federal legislation providing a structured plan for the nationwide smart meter rollout including basic product requirements, actors within the energy market have the opportunity to take an active part in shaping the market through appealing product offers and hence to create competitive advantage. This study identifies relevant features of smart meters from literature und business practice, and measures customer’s preferences for these features. Results indicate predominantly positive customer evaluations of smart meter features, amongst which the availability of consumption data, the installation price and rental charges as well as time variable tariffs contribute most to overall utility of smart meters. Finally, findings suggest targeting customers by defining strategies to address privacy concerns, to educate about saving potentials as well as to create differentiated pricing schemes. 相似文献

This paper studies the design of power exchanges in liberalized electricty markets. We analyze several pricing rules for day ahead trading and show that a uniform price mechanism has quite desirable properties as compared to its alternatives. We then discuss how the particular cost structure of electricity generation can be accounted for by appropriate bid formats. We moreover analyze the effects of bid caps and price floors in electricity auctions on market performance, as well as several other aspects of electricity market design. In particular, we discuss linkage of independently operating markets for electricity, reserve energy and transmission capacities, coupling of national power exchanges, and the effects of transparency on the outcome of electricity markets. 相似文献

With the third trading period of the EU emissions trading scheme (EU ETS) starting in 2013, the system of allocating emission
allowances will significantly change: In contrast to the previous two trading periods, auctioning of the allowances should
now be the rule rather than the exception. Accompanying this policy change, concerns over competitiveness of energy intensive,
trade exposed sectors as well as over limited environmental effectiveness via the channel of carbon leakage, have regained
prominence. In this paper, we thus explore the impacts of potential EU policies to counter losses in international competitiveness
and carbon leakage from the perspective of Austria. Based on numerical simulations with a computable general equilibrium model,
we evaluate three policy options: an input subsidy for carbon allowances (thus reflecting the planned partially free allocation
mechanism in the third EU ETS phase), a subsidy for domestic production, and an export rebate based on sectoral CO2 costs. Our results show that each policy has the potential to support domestic production in exposed sectors relative to
a full auctioning scenario and thus increase competitiveness. However, none is imperatively effective at reducing Austria’s
net carbon emissions: while the carbon trade balance is improved and hence leakage declines, the tradability of emission permits
within the EU ETS allows CO2 emissions from Austria’s ETS output to increase. A cost benefit analysis indicates that the two policies promoting domestic
output and exports are more cost effective than the CO2 input subsidy. 相似文献

Akut dekompensierte Herzinsuffizienz - Rund zwei Millionen Menschen in Deutschland
leiden an einer Herzinsuffizienz. Vor allem Dekompensationen des Krankheitsbildes
gef?hrden die Patienten und führen zu wiederholten Krankenhauseinweisungen. Ursache:
Oft falsche Medikamenteneinnahme oder die mangelnde Umsetzung von Verhaltensrestriktionen. Pflegekr?fte müssen bei ihrer Arbeit
daher verst?rkt auf Aspekte der Patientenedukation
setzen. 相似文献

We compare sequential and bundle procurement auctions in a framework of successive procurement situations, where current success
positively or negatively affects future market opportunities. We find that in bundle auctions procurement cost is lower and
less risky than in sequential standard auctions, but still higher than in the optimal sequential auction. Only a sequential
second price auction leads to the efficient outcome. 相似文献

There is growing interest in the positive organizational literature in the complex interplay between the positive and negative facets of organizations, individuals, and situations. The concept of courage provides fertile ground to study this interplay, since it is generally understood to be a positive quality that is manifested in challenging situations. The empirical study presented here looks at courage in a strategic decision-making context and takes an interpretive perspective; it focuses on the cognitive structures and subjective understandings of managers and administrators involved in merger projects as a way to understand the dynamics surrounding managerial courage. Our study makes several contributions: it shows that managers consider courage to have a moral dimension, e.g., to be a positive and ethical response to a risky or difficult situation in which there is an interplay between organizational and personal interests; it identifies two kinds of managerial moral courage; it proposes a conceptual model with which to understand how evaluations of what is courageous and what is not are made; and finally, it offers four schemas developed from the data that add to our understanding of moral courage in management. 相似文献

This article provides an analysis of laws across all 193 United Nations countries that protect workers from discrimination in access to employer‐provided training. We assessed the overall level of protection and the characteristics most commonly protected, as well as the extent of variation across geographic regions and country income. Overall, 60% of countries were found to offer specific protections from discrimination in access to training for at least one of the seven protected characteristics, which was significantly less than the percentage of countries offering protections from discriminatory hiring or terminations. Gender was the most commonly protected characteristic, whereas sexual orientation was least commonly protected. These findings suggest that employer‐provided training is less well‐protected from discrimination when compared with other aspects of employment and that there is variation in protection across socio‐demographic characteristics and geographic regions. Additional legislation may be needed to ensure equitable access to training for all workers. 相似文献

The second–generation (GSM) spectrum auction in Germany is probably the most clear cut example of a low price outcome in a simultaneous ascending-bid multi-unit auction. The present paper gives an account of the events, describes the auction rules and market conditions, and provides a game theoretic explanation of low price equilibrium in simultaneous, ascending-bid multi-unit auctions. In particular, it is shown that in the unique equilibrium that survives iterated elimination of dominated strategies, the efficient allocation is reached at minimum bids. 相似文献

This paper analyses energy relations concerning natural gas between Lithuania and Russia. Contrary to the existing literature, which stresses Lithuanian energy dependence, this paper argues that there had been interdependence between the two countries even before Lithuania underwent diversification at the end of 2014. The paper develops an analytical framework that examines: (a) physical energy relations, (b) the dominance of the energy agenda in mutual relations, and (c) the influence of the European Union. The analysis shows that while Lithuania was dependent on Russian supplies of natural gas, Russia was also dependent on Lithuania as a transit country of gas to Kaliningrad, a Russian enclave. Although Russia has shown a much higher willingness to employ an energy weapon than Lithuania, its efforts to exercise pressure on Lithuania have been negatively affected by the Baltic state’s position as a transit country. The European Union has played a crucial role as its pre-accession requirements and internal energy market rules have significantly influenced the energy relationship between the two countries. 相似文献
