Innovation portfolio management (IPM) is a dynamic decision‐making process, in which projects are evaluated and selected, and resources are allocated. Previous research has developed an understanding of IPM success and its influencing factors. However, little research investigated the quality of the decision‐making process and the ability to quickly adapt the portfolio. This study focuses on the antecedents of decision‐making quality and agility (i.e., responsiveness to changes in the environment). Based on a decision‐making framework, five structural and cultural IPM components are derived as important antecedents of decision‐making quality, which in turn influences agility. The structural components (1) clarity of strategic goals, (2) formality of the IPM processes, and (3) controlling intensity serve a coordinating function. The cultural components (4) innovation climate and (5) risk climate serve a motivating function in IPM. An analysis of a sample of 179 firms and their innovation portfolios through structural equation modeling using a double‐informant design documents that these five components all positively influence portfolio decision‐making quality, which in turn positively influences agility. Results further show that environmental turbulence moderates some of these relationships. While the positive effect of process formality is weakened under increasing turbulence, the effects of controlling intensity and climate for innovation are strengthened by environmental turbulence. The findings have theoretical implications for the understanding of IPM as a dynamic capability and practical implications for the management of portfolios in turbulent environments. 相似文献

The implementation of smart meters in German households by 2032 is a major step in the transition towards an intelligent and connected energy system. Despite of federal legislation providing a structured plan for the nationwide smart meter rollout including basic product requirements, actors within the energy market have the opportunity to take an active part in shaping the market through appealing product offers and hence to create competitive advantage. This study identifies relevant features of smart meters from literature und business practice, and measures customer’s preferences for these features. Results indicate predominantly positive customer evaluations of smart meter features, amongst which the availability of consumption data, the installation price and rental charges as well as time variable tariffs contribute most to overall utility of smart meters. Finally, findings suggest targeting customers by defining strategies to address privacy concerns, to educate about saving potentials as well as to create differentiated pricing schemes. 相似文献

The Impact of an increasing share of RES-E on the Conventional Power Market — The Example of Germany
The intermittency of wind power has a decreasing effect on day-ahead spot prices. Data from Germany illustrate this effect
and explain the underlying relationships. This short-term price effect leads to an adaptation process in the conventional
generation capacity mix. In the long-run, a higher peak load plant share is required to cope with the increasing volatility
of the residual demand. The result is an adapted merit-order. This merit-order intersects with an increasingly volatile residual
demand curve and leads to a higher price volatility in the power market, which is going to trigger further adaptations. Therefore
this article concludes with a list of open research questions, which can be derived from the illustrated relationship. These
research questions should be investigated as soon as possible in order to induce the required adaptations in time. 相似文献

This article presents joint econometric analysis of interest rate risk, issuer‐specific risk (credit risk) and bond‐specific risk (liquidity risk) in a reduced‐form framework. We estimate issuer‐specific and bond‐specific risk from corporate bond data in the German market. We find that bond‐specific risk plays a crucial role in the pricing of corporate bonds. We observe substantial differences between different bonds with respect to the relative influence of issuer‐specific vs. bond‐specific spread on the level and the volatility of the total spread. Issuer‐specific risk exhibits strong autocorrelation and a strong impact of weekday effects, the level of the risk‐free term structure and the debt to value ratio. Moreover, we can observe some impact of the stock market volatility, the respective stock's return and the distance to default. For the bond‐specific risk we find strong autocorrelation, some impact of the stock market index, the stock market volatility, weekday effects and monthly effects as well as a very weak impact of the risk‐free term structure and the specific stock's return. Altogether, the determinants of the spread components vary strongly between different bonds/issuers. 相似文献

The ongoing harmonisation of the European energy sector has led to gains from growth and increasing efficiencies by creating a common European internal market. However, there are new tendencies running against harmonisation in recent years, currently for example in the area of climate protection and the associated expansion of renewable energies. In addition to the role of national targets for climate protection in combination with a European emissions trading system, carrying out the related measures leads to distributional effects, both between countries and between stakeholders (e. g., producers and consumers) in these countries. We first analyse the impact of a non-harmonised national promotion schemes for renewable energies on electricity and CO2 prices in different countries. Then we illustrate the impact of harmonisation measures on producers and consumers in the participating countries. The analysis shows that these measures are indeed economically beneficial, but that—depending on the actual configuration—they can also lead to disadvantages for individual actors. Analysing and discussing these effects leads to a better assessment of the impact of certain measures and enables a better classification of individual market participants’ responses and opinions. 相似文献

Most analyses of the evolution of pay strategies in the last decade emphasize the macro–level components of changes, e. g. government policies, the crisis of tripartite negotiation. Yet more than a ‘push’ from the centre, we are witnessing a ‘pull’ from the periphery, the world of companies and management. New pay policies, both collective and individual, seem especially geared towards increase–ing the effectiveness of wages as a means of fostering employee motivation hence leading to a greater relevance of the company level and more differentiation in pay in response to segmented company labour markets. 相似文献
