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

In the second half of 2009, the entire media agenda in Germany was dominated by the swine flu, next to the German Federal Parliament elections. Criticism was voiced in the media against the pharmaceutical industry for lobbying the nationwide swine flu vaccination, which was widely considered nothing but a product of the industry’s lobbying power. In order to avoid the usual interviews with lobbyists, we attempted to apply a new methodological framework approach in analysing lobbying processes and key stakeholders in the public sphere—and outside. Crucial to the diversified approach, which involves quantitative content analysis of media coverage and press releases, are interviews with journalists, lobbyists’ network analysis and internet research on biographies. Although a conspiracy could not be conclusively proven, the results do indicate associations that validate the criticism of the industry’s lobbying activities.  相似文献

Increasingly, public sector organizations (PSOs) outsource the delivering of important welfare services. This gives rise to important questions of how PSOs can control their suppliers. The purpose of this paper is to show how PSOs manage cooperation hazards of low contractibility transactions, i.e., activities expected to be difficult to govern. The paper applies a taxonomic configuration approach which means we apply a holistic view on the governance of suppliers and search for internally congruent governance packages that also are adapted to the context of the transactions. We find indications of the importance of internal congruence in governance packages in order to effectively deal with cooperation hazards. We also notice that the intensity in and types of controls in inter-organizational relationships are affected by the amount of cooperation hazards. A conflict between a relational and a bureaucracy-based governance package in one of the configurations is argued to be the main driver behind lower expectations about positive behaviour from suppliers.  相似文献

In spite of the strategic importance of sustainability reporting in current business practice and the resulting increase in research on its value relevance, studies accounting for stakeholder interdependence are scarce. On the basis of the instrumental stakeholder theory, we investigate whether customers have an impact on the value relevance of sustainability reporting. Using a sample of US listed firms, we show that the value relevance of sustainability reporting is affected by customer profile differences, thereby confirming customer–shareholder interdependence. However, customer profile effects are only predominant if firms' profitability levels are low and disappear as profitability increases. Overall, our findings provide a more nuanced understanding of the value relevance of sustainability reporting. Therefore, we offer managers fine‐grained guidance for value relevant sustainability reporting. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment  相似文献

Carry     
We apply the concept of carry, which has been studied almost exclusively in currency markets, to any asset. A security’s expected return is decomposed into its “carry,” an ex-ante and model-free characteristic, and its expected price appreciation. Carry predicts returns cross-sectionally and in time series for a host of different asset classes, including global equities, global bonds, commodities, US Treasuries, credit, and options. Carry is not explained by known predictors of returns from these asset classes, and it captures many of these predictors, providing a unifying framework for return predictability. We reject a generalized version of Uncovered Interest Parity and the Expectations Hypothesis in favor of models with varying risk premia, in which carry strategies are commonly exposed to global recession, liquidity, and volatility risks, though none fully explains carry’s premium.  相似文献
