The regulation of water services in the EU

The European Commission’s proposal for a Directive on the award of concession contracts has sparked vigorous public debate and intense opposition. This Directive is controversial because of the nature of the policy it proposes and because the sectors involved are highly sensitive. This Forum examines the weaknesses of the Commission’s proposal and presents an overview of the current issues in water regulation and the provision of water services. The authors analyse the regulation of natural monopolies, water efficiency and upstream competition in the water industry.     

Der EU Richtlinienvorschlag für erneuerbare Energien — Eine Analyse der Transferrestriktionen von Herkunftsnachweisen

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”.     

Optimal Portfolios with Bounded Capital at Risk

We consider some continuous-time Markowitz type portfolio problems that consist of maximizing expected terminal wealth under the constraint of an upper bound for the capital at risk. In a Black–Scholes setting we obtain closed-form explicit solutions and compare their form and implications to those of the classical continuous-time mean-variance problem. We also consider more general price processes that allow for larger fluctuations in the returns.     

The Causal Relationship Between Real Estate and Stock Markets

This paper examines the dynamic relationship that exists between the US real estate and S&P 500 stock markets between the years of 1972 to 1998. This is achieved by conducting both linear and nonlinear causality tests. The results from these tests provide a number of interesting observations which primarily show linear relationships to be spuriously affected by structural shifts which are inherent within the data. Linear test results generally show a uni-directional relationship to exist from the real estate market to the stock market. However, these results are not consistent with financial theory and for all sub-samples of the data. In contrast, the nonlinear causality test shows a strong unidirectional relationship running from the stock market to the real estate market, and is consistent in the presence of any structural breaks.     

Potenziale zur Erhöhung des regionalen Markenkerns im Stromvertrieb am Beispiel der regionalen Grünstromkennzeichnung gemäß EEG 2017

The regional green power labeling according to the EEG 2017 represents an extension of the possibilities for labeling green electricity. In this paper we investigate the extent to which the implementation of regional green power products using the green power labeling regime under the EEG 2017 can help to strengthen the regional brand core of German power marketers, and which is the best alternative for raising the regional brand core of these firms. To this end, the different options for green power marketing with regional reference are discussed in detail, and it is elaborated which additional marketing models are enabled through the regional green power labeling. Furthermore, the criteria are identified with which the various green power labeling models with regional reference—with respect to their potential to raise the regional brand core—ought to be compared with each other. The results from our analysis show that the regional green power labeling based on EEG 2017 can be used to systematically upgrade the options for the marketing of regionally generated electricity already in place before the EEG 2017 entered into force.     

Crowdsourcing without profit: the role of the seeker in open social innovation

Crowdsourcing has increasingly been studied as an open innovation (OI) mechanism by which organizations (seekers) engage with an external crowd of potential solvers. Previous crowdsourcing research has focused on solvers and their individual motivations, providing few insights as to why and how seekers use crowdsourcing, and how these choices affect the value that might be realized from these efforts. Prior research has also emphasized profit‐seeking firms, despite the use of OI practices by public sector organizations to achieve societal benefits. This paper examines the organizational and project‐level choices of government agencies that crowdsource from citizens to drive open social innovation, and thus develop new ways to address societal problems, a process sometimes termed ‘citizensourcing.’ Using rich data from 18 local government seekers that use the same intermediary, we develop a model of seeker crowdsourcing implementation that links a previously unstudied variance in seeker intent and engagement strategies to differences in project team motivation and capabilities, in turn leading to varying online engagement behaviors and ultimately project outcomes. Our study compares and contrasts governmental and corporate crowdsourcing to reveal that the non‐pecuniary orientation of both seekers and solvers means that the motives of government crowdsourcing are fundamentally different from corporate crowdsourcing, but the process in our sample more closely resembles that of a firm‐sponsored community rather than government sponsored contests. More generally, we show how seeker organizational factors and choices shape project‐level implementation and success of crowdsourcing efforts, as well as provide insights for OI activities of other smaller, geographically bound organizations.

Does market power discipline CEO power? An agency perspective

We examine how product market competition (PMC) shapes chief executive officer's (CEO) power. Using various measures to capture both PMC and CEO power, our analyses, which include a quasi‐natural experiment, find evidence that CEOs have less power when the product market is more competitive. Furthermore, the impact of PMC on CEO power is more pronounced for firms with entrenched management, lower CEO ownership, lower analyst coverage, and for firms experiencing good ‘luck’ (windfall performance). Our results suggest that market power can act as a substitute for corporate governance in disciplining CEO power, particularly when prone to agency problems.
