Abstract
Die Software CO2-Navigator wendet den Realoptionsansatz und den Risikomanagementprozess auf den unternehmerischen Umgang mit dem Klimawandel an. Er richtet sich in erster Linie an emissionsintensive, kleine und mittlere Unternehmen ist jedoch auch in größeren Unternehmen, die beispielsweise eine eigene „Sustainability“-Abteilung unterhalten, anwendbar. Der Wertbeitrag des Softwaretools besteht darin, dass es die Aspekte Klimastrategie, quantitative Bewertung von Klimaschutzinvestitionen sowie Emissionsrechtemanagement vereint. Es kann im Unternehmen in Bereichen strategisches Management, regulatorisches Management, Energie- und Umweltmanagement, Technologiemanagement sowie Controlling Anwendung finden. Der spezielle Wertbeitrag dieses Artikels liegt in der Verknüpfung von Klimarisikomanagement und Realoptionsansatz sowie in der Darstellung des CO2-NAVIGATORs vor dem Hintergrund seiner Entwicklung im Sinne konstruktionsorientierter Forschung.

Klimaschutz und Anpassung an die Klimafolgen: Strategien, Maßnahmen und Anwendungsbeispiele,

Abstract
Global warming and increased climate policies are associated with risks for many companies, but also with opportunities.The chair of Business Administration, esp. Environmental Management at the TU Dresden and the Halle Institute for Economic Research studied the question of how companies can deal with these challenges funded by the BMBF project “Corporate Management under the Constraints of Climate Change Policy (CO2 Navigator)“.Specific concern of the project network was to provide companies assistance to develop a) potential emission reduction strategies and medium-term adjustments to changing environmental conditions, b) assess the economic impact and c) derive decisions for practical use on this basis.The core elements of the research, risk management and assessment of adaptation strategies with the real option approach and the CO2-Navigator software resulting from the project are described in this article.

The Economic Optimality of Sanction Mechanisms in Interorganizational Ego Networks – A Game Theoretical Analysis –
Muhamed Kudic, Marc Banaszak
IWH Discussion Papers,
No. 15,
2009
Abstract
Even though small- and medium-sized firms (SMEs) were believed not to proceed beyond exporting in their internationalization routes, we can observe new types of co-operation intensive entrepreneurial firms – so-called “micromultinational enterprises” (mMNEs) – entering the global landscape. These firms face the challenge to manage and control a portfolio of national and international alliances simultaneously (ego network). The aim of this paper is to provide game theoretically consolidated conditions in order to analyze the effectiveness and efficiency of interorganizational sanction mechanisms in an alliance portfolio setting. A game theoretical framework is developed over three stages with increasing complexity. Results show that two out of six analyzed sanction mechanisms do not fulfill the game theoretical condition for effectiveness. The efficiency analysis sensibilizes for discretionary elements in governance structures and demonstrates that not one single sanction mechanism but rather the right choice and combination of different types of sanction mechanisms leads to efficient results. We contribute to the international business, alliance, and network literature in several ways by focusing on alliance portfolios held by mMNEs. In doing so, we move beyond the dyadic level and analyze sanction mechanisms from an ego network perspective, a still widely under-emphasized topic in the literature.

Forecasting the CO2 certificate price risk
Henry Dannenberg, Wilfried Ehrenfeld
IWH Discussion Papers,
No. 5,
2008
Abstract
Modeling the price risk of CO2 certificates is one important aspect of integral corporate risk management related to emissions trading. The paper presents a risk model which may be the basis for evaluating the risk of emission certificate prices. We assume that the certificate price is determined by the expected marginal CO2 abatement costs prevailing at the current trade period and stochastically fluctuates around the respective level as returned from the mean reversion process. Due to uncertainties about future environmental states we suppose that within one trade period, erratic changes in the expected marginal abatement costs may occur leading to shifts in the price level. The aim of the work is to model the erratic changes of the expected reversion level and to estimate the parameters of the mean reversion process.

The European Emissions Trading System: What Have We Learned so Far?
Wilfried Ehrenfeld
Wirtschaft im Wandel,
No. 3,
2008
Abstract
The IWH occupies with the consequences of the emission trading for the effected companies. The first period of the European Emission Trading System was conceived as a learning phase during which two problems occurred: The first and most obvious one was the surplus of certificates. The incentives to invest in the mitigation of CO2 can therefore be considered to be low. The second problem resulted from the allocation which was entirely for free. While electricity customers had to bear the main financial burden, electricity producers profited as the certificate-prices were obviously added to the electricity-prices as opportunity costs. The analysis comes to the conclusion that it was right to shorten the amount of certificates on the EU-level for the second trade period and to establish the partly sales or auctioning of certificates in German legislation. Furthermore, the simplification of the allocation method in Germany can be considered to be a progress.

Property networks of corporations as cause of abusive behaviour – A stock market analysis based on institutional economics
Makram El-Shagi
Applied Financial Economics Letters,
No. 5,
2005
Abstract
The present study deals with the fact that it seems as if executive boards have developed a self-service-mentality concerning the corporations they are meant to manage. The surprise about this is not the attempt of exploitation (rather the opposite would be surprising from an economic point of view) but the apparent absence of sanctions imposed by the owners. This study shows that this behaviour of corporations’ owners is at least to a main part due to the fact, that the reciprocal property of corporations prevents the exercise of certain property rights by the ‘true’ holders.

The new social benefits scheme (Arbeitslosengeld II) and the Municipal Option Act
Herbert Buscher
Wirtschaft im Wandel,
No. 9,
2004
Abstract
One of the most important reform measures of the German labor market relates to the harmonization of social welfare and unemployment assistence to the new ‘”Arbeitslosengeld-II”. In the context of these reform measures it is expected that local employment offices and local authorities should constitute working parties to facilitate the unemployed in finding new jobs. In the case that a local authority prefers to manage this job in its own responsibility she has the right to opt. The paper discusses possible advantages and disadvantages of this option.
