The Galileo Project put to the test of European competition and public procurement law

The following article throws some light on the (fragile) legal foundations of the Galileo Project, the European Satellite Navigation System, and gives an interpretation of the normative procurement rules of the EU. Additionally it tries to reveal the practical problems of upholding the principle of free competition and an open market in as much as the procurement of high technology concerns a highly olipolistic market.     

Shifting frontier dynamics in Latin America

The concepts of resource frontier and commodity frontier are often treated interchangeably. This article suggests the benefits of clarifying these concepts because frontiers remain important analytics for understanding drastic land‐use changes and other socio‐environmental transformations. Based on long‐term field research in different parts of South and Central America, we use frontier concepts as heuristic devices to analyze heterogeneous frontier situations and make broader generalizations. Our synchronic and diachronic analyses of frontier dynamics elucidate different frontier modalities and shifting frontier expansions. The concept of commoditizing resource frontier is introduced to explain recent frontier‐makings in Brazilian Amazonia and Cerrado and in the Nicaraguan Río San Juan. Although earlier frontier research took a short‐term time perspective and created conceptualizations based on a single modality of a particular period, our longitudinal analysis shows that drastic changes and complex overlappings are the hallmarks of frontier dynamics.     

Time-Varying Betas of German Stock Returns

The market model assumes stock returns to be a linear function of the market return. However, there is considerable evidence that the beta stability assumption commonly used when estimating the market model is invalid. In this paper we account for beta instability in German stock returns by allowing the coefficients to vary over time in estimation. For time-varying beta estimation we rely on the Flexible Least Squares approach, the Random Walk Model and Moving Window Least Squares. Due to our results time-varying estimation fits the data considerably better than time-invariant estimation and, hence, increases the efficiency of beta based risk measurement.Acknowledgements: The authors thank Stefan Mittnik, Christian Pigorsch, an anonymous referee and the editor for constructive comments.     

Managing Dispersed Knowledge: Organizational Problems,Managerial Strategies,and Their Effectiveness

While there has been much progress in understanding organizational knowledge and knowledge management practices, some questions still remain unresolved. This paper argues that at least one important driver of knowledge‐related organizational problems has been rather neglected so far: that is, the dispersed nature of organizational knowledge. The paper analyses the organizational problems and managerial responses arising from dispersed knowledge. It identifies three drivers by which the dispersedness of knowledge leads to management problems: namely, it creates large numbers, asymmetries, and uncertainty. A number of managerial strategies for dealing with the different components of the problems created by the dispersedness of knowledge are identified and their effectiveness analysed, thereby informing managers as to how best to deal with dispersed knowledge. The analysis of uncertainty‐related implications of dispersed knowledge uncovers an overlooked distinction that is helpful for understanding dispersed knowledge and its managerial implications. This is the distinction between uncertainty and ambiguity, i.e. a strong form of uncertainty that cannot be remedied by the standard strategy of increasing the information available.     

Schumpeter 1911: Farsighted Visions on Economic Development

This paper presents to the English-speaking reader a sample of material contained only in Schumpeter's first German edition (1911) of Theorie der wirtschaftlichen Entwicklung , material subsequently omitted from later German editions and from the English translation. The newly-translated material, presented here for the first time in English, comprises a substantial part of the second chapter, only available in a completely rewritten version, and fully half of the famous seventh chapter, which has not been previously available at all in English. This material merits attention today because it contains remarkable and farsighted visions on economic theory that may inspire current efforts to devise models of economic and social evolution. In order to better appreciate the original text, we briefly introduce the "background" to Theorie and its revisions, briefly describing the social and intellectual environment of the time. We then discuss how the entrepreneur evolved over the three editions of Theorie (from 1911 to 1934) in view of the shift in Schumpeter's personal and intellectual life and outline the most important implications raised by the first German edition of 1911. Finally, we use Schumpeter's own statements to settle the obstinate confusion on the publication year of Theorie in favour of the year 1911.     

Changing investment styles: style creep and style gaming in the hedge fund industry

Notwithstanding their common features, hedge funds remain an extremely diverse asset class. Information on fund styles is important for numerous purposes, such as portfolio construction, performance attribution and risk management. With fund self‐declaration being prone to (strategic) misclassification, return‐based taxonomies grouping funds along similarities in realized returns provide a useful alternative. We provide a consistent classification system of homogeneous groups of hedge funds based on self‐organizing maps. Whereas some fund categories such as managed futures are largely consistent in their self‐declared strategies, others, especially so‐called ‘equity hedge’ funds, display no or very limited return similarities. Furthermore, we also find evidence of fund managers performing undisclosed changes of their trading style over time. Those funds that misclassified themselves once are particularly likely to change their trading style again. Although style self‐declaration can, therefore, be quite misleading, our results indicate that hedge funds do not misdeclare their style strategically to improve their relative performance.

Business Alignment: Versicherungsfachwissen als Kernkompetenz der IT

Information technology (IT) of insurance companies refers to the variety of organizational units that are in charge of development, implementation and operation of the specific entrepreneurial IT-applications. Our analyses follow the notion that nowadays information technologies departments face increasing cost pressure and the modern reflex of introducing outsourcing-and offshoring-measures does not necessarily lead to cost reductions. Therefore a closer cooperation of IT departments and other organizational units is crucial and strengthens the improvement of competitiveness of the entire insurance company. Furthermore a method leading to a gradual Business Alignment of IT departments within insurance companies will be introduced.     

Optimal Self-Reporting Schemes with Multiple Stages and Option Values

We consider a model of optimal law enforcement where sanctions can be reduced for self-reporting individuals. We distinguish between a first self-reporting stage before the case is investigated and a second one where the criminal is detected, but not yet convicted. Since we assume that violators have private information in both stages, fine reductions for self-reporting individuals lead ceteris paribus to a higher violation frequency. Nevertheless, we show that fine reductions should be granted in both stages. We characterize the connection between the two fine reductions in the optimal policy and relate our results to self-reporting schemes observed in reality.
