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...

This paper theoretically investigates how community approval or disapproval affects school attendance and child labor and how aggregate behavior of the community feeds back towards the formation and persistence of an anti- (or pro-) schooling norm. The proposed community-model continues to take...

This study provides a uni ed growth theory to correctly predict the initially negative and subsequently positive relationship between child mortality and net reproduction observed in industrialized countries over the course of their demographic transitions. The model captures the intricate...

We propose a simple and powerful method for determining the transition process in continuous-time DSGE models under Poisson uncertainty numerically. The idea is to transform the system of stochastic differential equations into a system of functional differential equations of the retarded type....

This paper examines the relative information shares of the Bund, i.e. the ten-year Euro bond future contract on German sovereign debt, versus two futures with shorter maturity. We find that the Bund is most important but does not dominate price discovery. The other contracts also have relevant -...

The global hunger indices of 2008 and 2009 (Grebmer et al. 2008, 2009) point to persistently high levels of hunger and food insecurity and a worsening of the situation due to rising crop prices. At the same time, there is a lack of empirical knowledge on the demand- and supply-side determinants...
