IT Products are viewed and managed differently depending on the perspectives and the stage within the life cycle. A model is presented that integrates different perspectives and stages serving as an aid for the analysis of business models and focused positioning of IT-products. Four generic business models are analysed with regard to the product management function in general and the positioning field for IT-products specifically: off-the-shelf (license), license plus service, project, and system service (incl. cloud computing).
We analyze the trading behavior of individual investors in option-like securities, namely bankissued warrants, and thus expand the growing literature of investors behavior to a new kind of securities. A unique data set from a large German discount broker gives us the opportunity to analyze the trading behavior of 1,454 investors, making 89,958 transactions in 6,724 warrants on 397 underlyings. In different logit regression, we make use of the facts that investors can speculate on rising and falling prices of the underlying with call and put warrants and that we also have information about the stock portfolios of the investors. We report several facts about the trading behavior of individual investors in warrants that are consistent with the literature on the behavior of individual investors in the stock market. The warrant investors buy calls and sell puts if the price of the underlying has decreased over the past trading days and they sell calls and buy puts if the price of the underlying has increased. That means, the investors follow negative feedback trading strategies in all four trading categories observed. In addition, we find strong evidence for the disposition effect for call as well as put warrants, which is reversed in December. The trading behavior is also influenced if the underlying reaches some exceptionally prices, e.g. highs, lows or the strike price. We show that hedging, as one natural candidate to buy puts, does not play an important role in the market for bank-issued warrants.
Wohnungseigentümergemeinschaft - Einstimmigkeitserfordernis bei Errichtung einer Mobilfunkantenne
(2014)
Der BGH (BGH v. 25.1.2014 – V ZR 48/13, MDR 2014, 399) hatte darüber zu befinden, ob auf dem Dach eines Hauses, das im Eigentum einer Wohnungseigentümergemeinschaft steht, auch gegen den Willen eines einzelnen Eigentümers eine Mobilfunkantenne angebracht werden kann. Das Urteil führt in das Spannungsfeld einer Abwägung zwischen Mehrheits- und Individualinteressen innerhalb einer WEG. Insoweit betont der BGH den grundsätzlichen Vorrang der Individualinteressen, jedenfalls soweit es um Beeinträchtigungen geht, die verständlicherweise von einem Eigentümer abgelehnt werden können. Der BGH verlangt im Ergebnis im Zweifel eine allseitige Zustimmung. Das Urteil ist zu begrüßen, lässt aber für die Zukunft Abgrenzungsfragen offen.
Knowledge-based productivity in “low-tech” industries: evidence from firms in developing countries
(2014)
Using firm-level data from five developing countries—Brazil, Ecuador, South Africa, Tanzania, and Bangladesh—and three industries—food processing, textiles, and the garments and leather products—this article examines the importance of various sources of knowledge for explaining productivity and formally tests whether sector- or country-specific characteristics dominate these relationships. Knowledge sources driving productivity appear mainly sector specific. Also differences in the level of development affect the effectiveness of knowledge sources. In the food processing sector, firms with higher educated managers are more productive, and in least-developed countries, additionally those with technology licenses and imported machinery and equipment. In the capital-intensive textiles sector, productivity is higher in firms that conduct R&D. In the garments and leather products sector, higher education of the managers, licensing, and R&D raise productivity.
