Impact Assessment was introduced by the European Commission in 2002 in order to make policy development more transparent and improve the ‘quality’ of European policies. Cross-sectoral consultation, broad participation and the quantitative assessment of the impacts of policies are significant elements of this process. This article specifically addresses the role of tools modelling the impact of policies on land use in Impact Assessment. The choice of a specific modelling tool is conceptualised as an action situation interlinked with other action arenas. The article aims to uncover the institutions structuring the action situation. The outcome of the empirical work suggests that two types of Impact Assessments can be distinguished. Impact Assessments either substantively contribute to the specific policy that the Commission proposes or they legitimise policy choices ex post that have already been adopted. The legislative procedure that applies to a specific policy sector, the policy making culture in the DG and the stakes that are at issue seem to influence whether Impact Assessments contribute to policy development, or legitimise it. Furthermore, the article describes the situation in which desk officers choose a modelling tool throughout Impact Assessment. To advance their careers desk officers aim to produce policy proposals which respond to the issues raised by the actors involved in Impact Assessment and specifically in policy development and, later on, adoption. Therefore, desk officers’ preferences are shaped by the community that is involved in policy development and Impact Assessment. The article describes what role modelling tools play in European Impact Assessment procedures and it names the heuristic of criteria which desk officers use to choose a modelling tool. Besides several technical and data problems of modelling land use impact, it seems to be unlikely that land use will become a significant dimension of Impact Assessment and modelling as it is confronted with an unfavourable institutional environment at the European level.  相似文献

Research and Development (R&D) is a key component behind technological development and economic growth; therefore, understanding the drivers of R&D is crucial. An interesting question is the role of technology spillovers, transferred by trade, and their impact on firm R&D. Here we analyze not only how international and domestic inter- and intra-industry technology spillovers affect firm R&D but also the relatively unexplored issue of how relationship-specific interactions between buyer and seller affect such spillovers. We find international technology spillovers to be larger and more significant than domestic inter- and intra-industry spillovers. Moreover, relationship-specific interactions between seller and buyer enhance technology spillovers in general and international spillovers in particular.  相似文献

Zusammenfassung  Der wertorientierte Ansatz der Unternehmensführung gewinnt immer mehr an Bedeutung; damit w?chst auch der Rechtfertigungsdruck für Aufwendungen des Dialogmarketing. Um den Ansprüchen der Wertorientierung Rechnung tragen zu k?nnen, muss das Dialogmarketingcontrolling neu ausgerichtet werden. In diesem Beitrag lesen Sie, wie ein Analyse- und Gestaltungsrahmen für ein wertorientiertes Dialogmarketing aussehen und wie Wertorientierung im Dialogmarketingmanagement erfolgen kann.

The EU suffers from a democratic deficit that arises not first and foremost from a lack of institutional competencies, but rather from the double weakness of politics vis-à-vis economics and law at the European level. This “functional democratic deficit” renders the existing mechanisms of democratic control increasingly ineffective. Especially for its citizens, a politically integrated Europen Union might be difficult to grasp, and it may only be reached gradually through a continuous process of dynamic development; however, “United in Diversity” seems to be the better alternative, and not only for historical reasons. The direct elections for the European Parliament, although not denying deficits of democratic legitimacy and participation at the Union level, should not be underestimated in their legitimising influence for the Union as an associated structure of members without obvious hierarchies.  相似文献

Ekzeme – eine h?ufig untersch?tzte Gefahr - Untersuchungen zeigen, dass die Lebensqualit?t durch berufsbedingte Hauterkrankungen genauso eingeschr?nkt wird wie durch einen Myokardinfarkt oder Schlaganfall. Das ist für Pflegende deshalb so bedeutsam, weil gerade in Pflegeberufen Kontakt zu potenziell Allergie ausl?senden Stoffen besteht.  相似文献

This paper shows that abnormal stock price returns around the date of open market repurchase announcements are four times higher in Germany than in the USA (12 ver. 3%). We hypothesize that this observation can be explained by national differences in repurchase regulations. Our empirical evidence indicates that German managers primarily buy back shares to signal an undervaluation of their firm. We demonstrate that the stringent repurchase process prescribed by German law attributes a higher credibility to undervaluation signals than do the lax US regulations, and thereby corroborates our hypothesis.Financial support from the E-Finance Lab, Frankfurt am Main, and from Freitag & Co., Frankfurt am Main, is gratefully acknowledged.
