Ownership unbundling of natural gas transmission networks: empirical evidence

The European Commission has intensively examined the mandatory separation of natural gas transmission from production and services. However, economic theory is ambiguous on the price effects of vertical separation. In this paper, we empirically analyze the effect of ownership unbundling of gas transmission networks, considered to be the strongest form of vertical separation, on the level of end-user prices. Therefore, we apply different dynamic estimators such as system GMM and the bias-corrected least-squares dummy variable estimator to an unbalanced panel consisting of 18 EU countries over 19 years, allowing us to avoid the endogeneity problem and to estimate the long-run effects of regulation. We introduce a set of regulatory indicators as market entry regulation, ownership structure, vertical separation and market structure, as well as account for structural and economic country specifics. Among the different estimators, we consistently find that ownership unbundling has no impact on natural gas end-user prices, while the more modest legal unbundling reduces them significantly. Furthermore, third-party access, market structure and privatization show significant influence, with the latter leading to higher prices.     

Firm-hosted online brand communities and new product success

Many firms use online brand communities to support the launch of their new products. This study proposes a typology of firm-hosted online brand communities and examines whether such a classification system can improve predictions of new product success. A cross-industry analysis of 81 firm-hosted online brand communities shows that these communities reflect three archetypes. A subsequent survey of 170 community-hosting firms in the consumer durable goods industry reveals that the three types of communities are not equally important for new product success. Moreover, one archetype generally underperforms the other two as a new product support mechanism. Overall, the results demonstrate that firm-hosted online brand communities can be a predictor of new product success.     

Disequilibrium,Reproduction and Money: a Classical Approach

We consider a bisector reproduction model in which money is introduced as a pure means of exchange issued by a bank at the producers' requests. Each capitalist aims at maximizing accumulation in his own sector. Their plans are based on available quantities and expected prices. Effective prices are determined by a market mechanism. Temporary disequilibria occur in both physical and monetary terms. The settlement of the monetary balances is operated by means of a transfer of capital goods. Final allocations and effective productions are thus determined. The dynamics of the economy are those of a sequence of temporary disequilibria and let appear several possibilities (local or global stability, cycles) depending on the values of the parameters.     

Do unfair perceived own pay and top managers’ pay erode satisfaction with democracy?

Many people are relatively unsatisfied with the democratic system as it currently exists. In this empirical research note, the authors present evidence that German workers, who perceive their own pay or top managers’ pay as unfair, are on average significantly less happy with the democracy in Germany. Thus, fairness perceptions in the labour market and of income inequality seem to have spillover effects on the overall satisfaction with the democratic system.     

Aktuelle Rechtsfragen der Umweltschadensversicherung

The paper provides an overview of current legal issues with regard to the environmental damage insurance, which exists in Germany since 2007. At the center of the observation are limitations of coverage, in particular the requirement of a malfunction of the business operations, the exclusion of qualitative risk changes and the cost deduction clause. In addition, the article deals with some issues of interpretation as well as of delimitation with regard to further insurance policies. By way of introduction the basics of the German Environmental Damage Act (USchadG) and its underlying EU Directive are shown. Finally, the authors discuss the question whether the environmental damage insurance should be configured as an obligatory insurance in the future.     

Training reflective processes in military aircrews through holistic debriefing: the importance of facilitator skills and development of trust

This paper explores how Holistic Debrief, a new concept in the field of debriefing and reflective processes, can contribute to restitution, reflection and learning in professional teams following stressful events and routine tasks. Interviews were conducted with Norwegian military aircrew mission commanders following deployment to Afghanistan in 2010. Phenomenological analysis in the frame of social learning theory revealed that reflective processes were easier to facilitate after stressful events than after routine tasks. Challenges identified included lack of trust during the early stages of team establishment and poor conceptual repertoires among aircrew commanders undertaking facilitation. Relational trust and reflective processes tended to improve after stressful events. Repeated interactions in Holistic Debrief tend to increase familiarity, trust and learning potential over time. This study reports data from the war context, an environment not often available for qualitative research. The findings are relevant for military and other operational units who wish to develop their debriefing practice and create an experience‐based learning environment.     

The Impact of Family Ownership,Management, and Governance on Innovation

Previous research suggests that the distinctive nature of family firms, including both specific advantages and disadvantages related to their particular agency situation, influences innovation activities. Most studies, however, view family firms as homogeneous entities and thus neglect the heterogeneity of family firms when comparing them with nonfamily firms. One important factor of this firm heterogeneity is family influence in terms of ownership, management, and governance. A data set of large German publicly traded firms between 2000 and 2009 is used to test how these three dimensions of family influence predict innovation input and output. The results show that family participation in management and governance has a negative impact on innovation input and a positive influence on innovation output. This suggests that family members are risk averse and reluctant to invest in innovation, but at the same time do so more effectively.
