      <description>Title: Information-driven clustering: An alternative to the knowledge spillover story
&lt;br/&gt;
&lt;br/&gt;Authors: Sievers, Tim
&lt;br/&gt;
&lt;br/&gt;Abstract: This paper builds a model in which clustering emerges as the equilibrium outcome driven by informational imperfections and the importance of knowledge and uncertainty in innovative production even when knowledge is fully exclusive and appropriable. This motive for clustering will be stronger the more important new knowledge in the industry. It thereby helps to account for the empirical finding that economic activity clusters more strongly in industries where new knowledge plays a bigger role. It weakens the case for local knowledge spillovers to explain innovative clustering.</description>

      <description>Title: Trends in competitive balance: Is there evidence for growing imbalance in professional sport leagues?
&lt;br/&gt;
&lt;br/&gt;Authors: Feddersen, Arne; Maennig, Wolfgang
&lt;br/&gt;
&lt;br/&gt;Abstract: The concept of competitive balance is a central aspect in the literature of sports economics. A popular argumentation of sport functionaries is that dominance of one or a few teams could lead to unequal incomes for the clubs, restrictions in the clubs' ability to improve sporting performance and ultimately to a loss of attractiveness and loss of income for the league. Following this line of reasoning and alleging a negative trend in competitive sports functionaries often try to implement regulations in team sport leagues. The aim of this paper is to analyze for eight different leagues if there is such a trend existing. For an empirical test for trends in competitive balance of four European soccer leagues (ENG, ESP, GER, ITA) and four US Major Leagues (MLB, NBA, NFL, NHL), OLS regressions with a constant were carried out. For the entire observation period from 1969/70 to 2003/2004, of 48 trends ascertained, only 12 could be observed as being significantly positive (i.e. growing imbalance) with 19 significantly negative (i.e. growing balance). The remaining 17 trends were insignificantly different from zero.</description>

      <description>Title: A vector-based approach to modeling knowledge in economics
&lt;br/&gt;
&lt;br/&gt;Authors: Sievers, Tim
&lt;br/&gt;
&lt;br/&gt;Abstract: This paper draws attention to two important characteristics of knowledge which so far have been left unexplored, and proposes a new method to capture them in economic modeling with the help of vectors. The direction of the vector represents the knowledge's complementarity with other knowledge and its norm represents its potential economic value.</description>

      <description>Title: Economic consequences of the UEFA Champions League for national championships: The case of Germany
&lt;br/&gt;
&lt;br/&gt;Authors: Feddersen, Arne
&lt;br/&gt;
&lt;br/&gt;Abstract: Qualifying for and participating in the UEFA Champions League (UCL) is associated with generating large revenue flows. The fear of the football associations, some journalists and fans is that a permanent financial and sporting imbalance will be created between clubs qualifying for the UCL and the remaining clubs. This paper analyses the consequences of the UCL on the national championship in the German Bundesliga. The first section shows a review of economic and sporting trends in the Bundesliga for the 1980-1997 period. Also main changes in the domestic championship are reviewed. In second section an analysis of the UCL with (a) regard to competitive balance and (b) with regard to general balance will be undertaken. An interesting question is whether clubs qualifying for the UCL differ from the other teams. Especially the question whether competitive balance changes when there is an imbalance in the financial situation of the clubs (enforced by the UCL) will be analyzed. The third section describes the regulatory mechanisms of the German Bundesliga like revenue sharing and the licensing system.</description>
