Virtual operators in the mobile industry: a techno-economic analysis

For a company planning to become a mobile operator, two alternative ways to enter the market exist. In addition to the traditional way of acquiring a spectrum license and building a mobile network, market entrance is also possible by becoming a virtual operator and utilizing the existing networks of incumbent operators. Potentially, virtual operators will have an important role in shaping the mobile market structure and competition. In this paper, techno-economic modeling methods are used to analyze the position of virtual operators in the mobile communications industry. Four alternative virtual operator scenarios are constructed and analyzed using a linear, deterministic, and quantitative techno-economic model. The results highlight the importance of wholesale contracts with incumbent mobile network operators in determining the virtual operators’ business profitability. Unbalance in termination prices between fixed and mobile networks is shown to give incentives for virtual operators to invest in their own network infrastructure.     

Die Privatisierung öffentlicher Wohnungen

Seit 1997 wurden rund 700 000 Wohnungen aus ?ffentlicher Hand privatisiert. Welche Auswirkungen hat diese Ma?nahme auf den Wohnungsmarkt? Ist es aus sozialpolitischen Gründen notwendig, dass Wohnungen in ?ffentlichem Besitz verbleiben? Kann die sozialpolitische Komponente auch mithilfe von Belegungsrechten gel?st werden?

Earnings dynamics of men and women in Finland: permanent inequality versus earnings instability

I decompose the earnings variance of Finnish male and female workers into its permanent and transitory components using the approach of Baker (J Labor Econ,15:338–375, 1997) and Haider (J Labor Econ, 19:799–836, 2001) in the spirit of scientific replication. I find that the increasing earnings inequality of men and women is driven by both the transitory and permanent components of earnings. In addition, I find considerable differences in the earnings dynamics of men and women, that have been largely neglected in previous studies of earnings dynamics. The inequality among men is dominated by the permanent component. Conversely, permanent and transitory components are of comparable magnitudes to women. As a corollary, men experience more stable income paths but display larger permanent earnings differences. Women, on the other hand, face more unstable earnings profiles but show smaller permanent differences in earnings.     

Ist die EU-Agrarpolitik ihr Geld wert?

Expenditure for the Common Agricultural Policy (CAP) has been in the centre of recent policy debate in the preparation of the Financial Framework for the period 2014–2020. Expenditure has generally been considered as the necessary costs for the achievement of the CAP objectives. The authors of this article argue that expenditure is not equal to the economic costs of a policy. Moreover, they claim that the main part of CAP expenditure is not well targeted for the achievement of the CAP’s objectives. The bulk of expenditure is for direct payments tied to agricultural land and, hence, contributes little if anything to CAP’s objectives as laid down in the treaties of the European Union or officially articulated elsewhere.     

Dynamic capabilities and firm performance in a financial crisis

In this study, an organization means an active actor that can, at least to some extent, adapt to the environment, mainly within the limits of its resources and capabilities. The article enhances understanding of and explains organizational adaptive behavior in weathering the storm in the business environment resulting from the global financial crisis of 2008. The literature on dynamic capabilities, organizational change, and innovation in the context of organizational performance and survival captures this kind of adaptive behavior. The empirical study builds on a quantitative survey and a qualitative case study covering the food processing, maritime, and media industries. Structural equation modeling, group analysis, and qualitative case comparisons shed light on the connection between the constructs in question. Implications for theory and practice culminate in suggestions for future research.     

Die Schuldenbremse der Bundesländer: eine Fehlkonstruktion?

The debt brake for the German Länder, which forbids them from taking on new net debt beginning in 2020, has two major shortcomings. First, the Länder do not have tax autonomy. In fiscal crises, they can only adjust on the expenditure side, not on the revenue side. Given the fact that most expenditure is predetermined by law, in such a crisis, a balanced budget without new debt would hardly be feasible. Second, it is not taken into account that, in particular in small regional units, large investments can hardly be financed by current expenditure. Thus, there is a very high probability that at least some Länder will still take on new net debt after 2020 and, therefore, violate the rules of the debt brake.     

Does it Pay to Be Ethical? Examining the Relationship Between Organisations’ Ethical Culture and Innovativeness

In this article, we examine the relationship between ethical organisational culture and organisational innovativeness. A quantitative empirical analysis is based on a survey of a total of 719 respondents from all levels of three Finnish organisations, both general staff and managers. The organisations belong to both the private and public sectors. The results of this study show that organisations’ ethical culture is associated with their organisational innovativeness, and that different dimensions of ethical culture are associated with different dimensions of organisational innovativeness. The ethical culture of the organisation had a specific role in process and behavioural innovativeness. It was found that congruency of management was the single dimension with the highest effect on organisational innovativeness overall and specifically on process and behavioural innovativeness. These findings suggest that when organisations are aiming for specific outcomes, such as organisational innovativeness, they need to be aware of what dimensions of ethical culture are particularly relevant.     

What is being exchanged? Framing the logic of value creation in financial services

Financial service providers are facing a major paradigm shift. The understanding of what eventually constitutes customer value is being extended; economic value as the sole core of exchange is a far too limited perspective in contemporary competition. To address this emerging shift, the purpose of this study is to reframe the logic of value creation in financial services. As a result, a tentative framework for value creation logic in financial services is developed and discussed. On the basis of the framework, financial service providers should not limit their attention and resources to the exchange process, but identify innovative value-creating mechanisms through which they could contribute to the customer value actualization process. Our tentative framework (i) offers financial service providers guidance on which innovative value-creating mechanisms would enable them to participate in their customers’ value actualization process; (ii) shows how a product becomes a channel for a service, specifically a solution possessing value in the customer’s routine processes; (iii) illustrates that researchers and service providers should develop their understanding of customers beyond the traditional loan, insurance and/or investment product orientation.
