The present study investigates impacts of attitudinal and perceptual characteristics of residential electricity consumers on their intention to use a green power tariff/supplier in the future. The work rests on a standardized telephone survey of 267 household electricity consumers of a German power supplier. Multivariate Partial Least Squares analysis indicates that, regardless of a person’s level of actual power consumption in the recent past, the intention to use green electricity is significantly higher among customers who have a positive general attitude towards environmental protection measures and who report an endorsing valuation of green power by their close social contacts. In a subsample of participants with a low actual electricity consumption in the year preceding the survey the intention to use green energy is significantly positively affected by the weight an individual attaches to electricity prices in one’s own supplier selection decisions and the person’s belief that one’s present power company takes over social responsibility. In contrast, in the subgroup of respondents with a high actual electricity consumption customers’ intention to use green energy is significantly enhanced by the degree of perceived dissimilarity among power company offerings. The findings are used to derive suggestions for green energy marketing measures of power companies and future energy consumer research. 相似文献

A successful implementation of CO2-capture in power plants is mainly depending on the energy political or economical environment. The future role of lignite and hard coal power production varies widely in presumed energy scenarios. This report considers the actual projections of BDEW. Increasing demand, the replacement of old plants and the compensation of efficiency losses due to CCS-technology cause highly ambitious expansion rates, assuming a retrofit time horizon of 10 years starting in 2020. The corresponding coal demand increases strongly. Therefore, a solely concentration of CO2-reduction potential is not sufficient. Other environmental impacts triggered through emissions are low compared to the total German impacts. Nevertheless, the compliance with national ceilings for NOx emissions for example can only be reached by compensation measures in other sectors. 相似文献

In this paper we use simulations to examine how endogeneity biases the results reported by ordinary least squares (OLS) regression. In addition, we examine how instrumental variable techniques help to alleviate such bias. Our results demonstrate severe bias even at low levels of endogeneity. Our results also illustrate how instrumental variables produce unbiased coefficient estimates, but instrumental variables are associated with extremely low levels of statistical power. Finally, our simulations highlight how stronger instruments improve statistical power and that endogenous instruments can report results that are inferior to those reported by OLS regression. Based on our results, we provide a series of recommendations for scholars dealing with endogeneity. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

The effect of unions on profits continues to be an unresolved theoretical and empirical issue. In this paper, clustered data analysis and hierarchical linear meta‐regression models are applied to the population of forty‐five econometric studies that report 532 estimates of the direct effect of unions on profits. Unions have a significant negative effect on profits in the United States, and this effect is larger when market‐based measures of profits are used. Separate meta‐regression analyses are used to identify the effects of market power and long‐lived assets on profits, as well as the sources of union‐profit effects. The accumulated evidence rejects market power as a source of union‐profit effects. While the case is not yet proven, there is some evidence in support of the appropriation of quasi‐rent hypothesis. There is a clear need for further American and non‐American primary research in this area. 相似文献
