This study examines the role of top management team (TMT) member succession in breaking organizational inertia. We compare
the impact of two types of change in TMTs—in member number and demographic heterogeneity—on subsequent strategic reorientation
using data on the diversification activities of firms in the Japanese textile industry. Our findings suggest that executive
succession does not trigger strategic change unless succession entails change in the values and interests of executives embedded
in their demographic traits.

In order to restrict the risks of anthropogenic climate change to a ?tolerable“ extent, the fourth assessment report of the United Nations’ International Panel on Climate Change calls for a trend reversal towards globally decreasing greenhouse gas emissions within the next two decades which ultimately must lead to a reduction of carbon dioxide emissions until the mid of the century by 50 percent as compared to 2000 emission levels. The European Union claims a lead of a role in climate policy with the objective to push forward international negotiations on far-reaching emission reduction commitments with other important industrialized and developing regions. The EU’s credibility as a leading force will hinge crucially on how successfully it can fulfill its emission reduction obligations under the Kyoto Protocol by means of market-based environmental policy, in particular the exemplary operation of the EU emission trading system. Against this background, the following article provides a critical assessment of the EU’s climate policy. 相似文献

This study estimates the impact of demographic change on energy use in two German regions, Hamburg and Mecklenburg-Western Pomerania. Data from the EVS household survey are used to identify demographic characteristics and age-specific consumption patterns in the two regions. They are used in combination with regional household projections to construct consumption expenditure forecasts, which are then entered as demand impulses into regional input-out-put models to calculate sectoral production effects and energy use. The analysis shows that the impact of demographic change on energy use differs considerably between the two regions. Therefore, studies conducted at the national level may miss important effects, making it necessary to conduct more studies at the regional level. 相似文献

Until now the promotion of renewable energies in Europe has been effected on the basis of different promotion systems of the Member States. Currently the EU-wide harmonisation of the promotion systems, from which yields of efficiency and a higher effectiveness are expected, cannot be enforced due to a discordance concerning the “right” promotion instrument.With the proposal for a directive on the promotion of renewable energies, published at the 23. January in 2008, the European Commission attempts to make a first move towards harmonisation. Besides existing promotion systems it will be possible to transfer Guarantees of Origin for renewable energies between Member States. Since, however, some Member States expect negative effects as a consequence of opening their markets the proposal comprises opportunities to restrict the transfer. The present scope of interpretation within the proposal allows for different options concerning the design of the transfer restrictions. These will be identified, analysed, and subsequently evaluated in this article. Despite of both extreme options, the possibility to entirely opt out of the transfer system and the obligation to completely participate in the transfer system, two further hybrid options are discussed. The latter are characterised by the possibility of Member States to restrict the transfer of Guarantees of Origin to a certain extent through a “system of prior authorisation”. 相似文献

The main goals of this study were to look after the technological knowledge construction process by high-school high-achievers,
and their ability to design and implement solutions for technological problems. More specifically, we examine the contribution
of Project-based-learning (PBL), as pedagogical means for supporting the students’ knowledge acquisition and problem-solving
process. The findings show a significant increase in formal knowledge as measured by standardized matriculation exams; an
expansion in the scope of technological knowledge acquired and implemented, and in the scope of knowledge resources utilized
for the projects; a high level of overall performance as regards to the set of design skills studied; a positive change in
attitude towards technology and technological studies; the emergence of consistent design styles by individuals and groups
along their work in the projects. 相似文献

The contextual relevance effect is an important factor for the effectiveness of financial services advertising that corresponds to the message effects such as ad recall (RAD), perceived contextual relevance (PCR), message involvement (MI) and attitude towards the ad (AAD), created during the process. Thus, this study examines whether the contextual relevance effect increases RAD, PCR, MI and AAD. The results reveal that the contextual relevance effect increases RAD, PCR, MI and AAD. Moreover, MI mediates PCR on AAD. Implications based on the findings demonstrate the importance of contextual relevance as a metric for financial services advertising effectiveness. 相似文献

Schlinger's Viewer Response Profile is a widely used tool in advertising research, in both commercial and academic environments. It is used in ad testing to gauge viewer reactions to television commercials. Initial research on its psychometric properties was critical of the scale; however, more recent work using more sophisticated statistical techniques and larger, more realistic, samples has been much more complimentary. This article reports on the use of a shorter version of the Schlinger scale to test financial services advertisements. The findings generally indicate that the scale can be used with confidence in that environment, and that the shorter scale generally performed well. The limitations of the study are acknowledged, managerial implications are discussed, and avenues for future research are identified. 相似文献

The authors offer a new perspective to the field of guaranteed minimum death benefit contracts, especially for simple return premium and rising floor guarantees. A particular feature of these contracts is a guaranteed capital upon the insured's death. A complete methodology based on the generalized Fourier transform is proposed to investigate the impacts of jumps and stochastic interest rates. This paper thus extends Milevsky and Posner (2001). If jumps alone are considered, similar results are obtained, but, when stochastic interest rates are introduced, the fair costs of the guarantee feature are found to be substantially higher in this more general economy. 相似文献

We analyze the factors that drive exercise price policy for executive option plans (ESOPs) and their scope in a country where firms are not subject to the tax and accounting considerations that seem to have led to the dominance of at-the-money options in the US Our “unbounded” data for Finland provide us with an excellent opportunity to investigate whether contract design is consistent with compensation theory. Our findings are largely consistent with predictions from the optimal contracting literature. The size of the plan is negatively related to Tobin's Q and firm size and positively related to proxies for monitoring costs, which also influence the probability of launching premium ESOPs. Our results also show that the premium (out-of-the-moneyness) is negatively related to prior stock returns and cash flow-to-assets, which may be an indication of high-water mark contracting, or alternatively, of managerial power. Finally, we also find some support for a positive relation between the premium and the length of the vesting period when maturity is fixed, which indicates an effort to keep the incentives for management from falling over time. 相似文献
