This study provides novel empirical insights into the attractiveness of European Universities for Marie Skłodowska-Curie Actions (MSCA) grant holders and investigates how efficient universities are in this respect relative their potential. To explore the attractiveness, factors explaining both...

This paper introduces Quasi-Maximum Likelihood Estimation for Long Memory Stock Transaction Data of unknown underlying distribution. The moments with conditional heteroscedasticity have been discussed. In a Monte Carlo experiment, it was found that the QML estimator performs as well as CLS and...

We introduce a dynamic statistical model for Skellam distributed random variables. The Skellam distribution can be obtained by taking differences between two Poisson distributed random variables. We treat cases where observations are measured over time and where possible serial correlation is...
