There is now almost universal agreement that climate change, with potentially disastrous consequences, is happening and that it is contributed to by human activities. This Forum is dedicated to the discussion of various aspects of the European Union's climate policy, e.g. the EU's future role in the global effort to combat global warming, the efficiency of its climate strategy, the design of a new rule for sharing the corresponding burdens fairly among member states, and the interrelationships between the Union's climate policies, on the one hand, and its energy and transport policies, on the other. * and member of the German Advisory Council on Global Change (WBGU). The author wishes to thank Helen Bicknell (Mainz University of Applied Sciences), Oliver Deke (WBGU) and Jürgen Schmid (ISET, Department of Efficient Energy Conversion at the University of Kassel) for their helpful comments. ** This contribution is based on a Jean Monnet Lecture held at Aarhus University on 19 March 2007. The author would like to thank Harri Kalimo for valuable comments.  相似文献

The digital transformation of the healthcare branch is important and unstoppable. The enormous possibility of digitalisation to redesign and enhance processes has been shown in other branches. Digital technologies offer the similarly large potential to improve the quality and efficiency of healthcare services. However, in terms of digitalisation, the German health system lags behind other European countries. But given a lack of available evidence, the effects of the digitalisation of the healthcare system cannot be reliably evaluated. Digital access to patient data necessitates constructive error cultures in organisations in order to limit defensive medicine. And digital access to health information necessitates individual competence in searching and using this information for participatory decision-making. As with all technological progress, information security is very important in order to gain citizens’ confidence in a digital healthcare system. Thus, it is necessary to simultaneously pursue both enhanced privacy standards and state-of-the-art medical technology.  相似文献

Öffentlich gesicherte Exportgarantien und –bürgschaften bilden die Grundlage der staatlichen Ausfuhrförderung in Deutschland. Wie sind Exportkredite aus ordnungspolitischer Sicht zu bewerten? Welche Risiken werden in der Praxis abgedeckt? Gibt es Anlass, die mittel– und langfristige Exportfinanzierung der Unternehmen zu reformieren?Dr. Karl–Wolfgang Menck, 63, ist wissenschaftlicher Mitarbeiter im Forschungsschwerpunkt Handel und Entwicklung im Hamburgischen Welt–Wirtschafts–Archiv (HWWA) in Hamburg.  相似文献

Recent changes in many areas of Government policy as well as changes in the private sector have had major impacts on the provision of services in rural areas of New Zealand. This report describes the results of a New Zealand survey of 795 rural consumers. The results emphasise how the problems perceived as most important to people in rural areas are essentially linked to fundamental services such as housing, water, communications, and transport. Though this element of basic needs is covered in the consumer policy literature it is not a feature that tends to be emphasised. The survey also gauges some aspects of rural consumers' knowledge of their entitlements under New Zealand consumer law and their familiarity with, and use of, consumer advisory and support services.  相似文献

Auf ihrem letzten Gipfeltreffen Ende M?rz haben die europ?ischen Staats- und Regierungschefs einen Europ?ischen Stabilisierungsmechanismus für die Zeit nach 2013, eine Sch?rfung des Stabilit?ts- und Wachstumspaktes und einen Euro-Pakt-Plus beschlossen. Dies soll dazu führen, dass die Wirtschaftspolitik der Eurol?nder besser koordiniert wird. Der Autor ist allerdings skeptisch, ob eine gelenkte Koordinierung die richtige Strategie ist. Für die L?sung der europ?ischen Probleme h?lt er den Marktmechanismus für geeigneter.  相似文献

We use a nonlinear commodity market model to assess, theoretically and empirically, the impacts of recent reforms of the CAP on prices and economic welfare in the EU. The empirical analysis is based on an aggregate structural econometric model of the EU wheat economy and its links to the rest of the world. Instability issues are also investigated. Impacts of CAP reforms on the variance of domestic and world prices are analysed and a Monte Carlo simulation is used to evaluate uncertainty in the model's welfare computations. Recent reforms led to a net welfare gain within the EU during the period 1993–2000. Additional budgetary costs are less than the welfare gains of consumers and producers. Producers gained as lower price support was overcompensated by additional direct payments.  相似文献

As an editorial to the special issue “new avenues in international careers research” this article discusses the roots of the international careers research stream, which sits at the intersection between career studies, HRM and international management. In order to support future studies in this emerging area of enquiry, we attempt to lay down the foundations of a research agenda based around what we see as the three core areas of interest: contextualised careers research, comparative careers research and careers research in internationally operating organisations. After providing some suggestions for the kinds of theoretical and methodological tools that will be required to build on these foundations, we introduce the five empirical papers that comprise this special issue.  相似文献

We characterize the equilibrium of the all-pay auction with general convex cost of effort and sequential effort choices. We consider a set of n players who are arbitrarily partitioned into a group of players who choose their efforts ‘early’ and a group of players who choose ‘late’. Only the player with the lowest cost of effort has a positive payoff in any equilibrium. This payoff depends on his own timing vis-a-vis the timing of others. We also show that the choice of timing can be endogenized, in which case the strongest player typically chooses ‘late’, whereas all other players are indifferent with respect to their choice of timing. In the most prominent equilibrium the player with the lowest cost of effort wins the auction at zero aggregate cost. We thank Dan Kovenock and Luis C. Corchón for discussion and helpful comments. The usual caveat applies. Wolfgang Leininger likes to express his gratitude to Wissenschaftszentrum Berlin (WZB) for its generous hospitality and financial support.  相似文献
