This article examines the question whether a point and figure (P and F)-based investment strategy yields statistical significant excess returns compared to a buy-and-hold (B and H)-strategy. The simulations show that P and F slightly outperforms B and H with respect to returns as well as with...

In this paper the efficient market hypothesis in its weak form and the existence of a Monday effect is examined for German stock returns. Using the first order autocorrelation coeffients, a method is developed to test for the existence of finite moments for daily returns. Therefore, simulations...

The Matching Distribution converges to a Poisson Distribution with lambda=1 as the parameter n converges to infinity. A generalization of the Matching Distribution is proposed. The properties of this Generalized Matching Distribution (GMD) turn out to be analogical to the case with lambda=1.

In this paper the genetic algorithm is described, applications in the field of statistics are indicated and it is applied to the estimation of the parameters of a Johnson-type distribution. The convergence behaviour is analyzed with respect to the mutation probability, the kind of mutations and...

In this paper models for the prediction of matches in the German Soccer Bundesliga are estimated. In a frst step the expected difference of the number of goals is estimated on the basis of estimated abilities of the teams. Here, a focus lies on the necessity of robust parameter estimation. In a...

It's puzzling that most projects fail to complete within the predetermined timeframe given that timing considerations rank among the major goals in project management. We argue that when managers can extract private benefits from working on a project, project delay becomes optimal. We introduce...

I analyze the long-term labor market returns after completing a higher education entrance (HEE) qualification as a qualified worker older than age 20 (Zweiter Bildungsweg), using data of the German National Educational Panel Study (NEPS). I use a Mincer-type equation, where the school-leaving...

This paper discusses the central macroeconomic claims that are made in Thomas Piketty's book 'Capital in the Twenty-first Century'. The paper aims to show that Piketty's contentions are not only logically flawed but also contradicted by his own data.

The question of whether migration can be an equilibrating force in the labour market is an important criterion for an optimal currency area. It is of particular interest currently in the context of high and rising levels of labour market disparities, in particular within the Eurozone where there...

While the worldwide spread of smartphones continues, developing countries have become important markets for these devices. Smartphones´ independence of landline networks qualifies them for communication and Internet access in rural areas of developing countries. Drawing upon rural Southeast...
