In this paper we propose several goodness-of-fit tests based on robust measures of skewness and tail weight. They can be seen as generalisations of the Jarque-Bera test (Bera and Jarque, 1981) based on the classical skewness and kurtosis, and as an alternative to the approach of Moors et al....

As many international economic issues are interrelated, the competences of international economic organizations are not always clear-cut and their activities inevitably overlap. In order to avoid mutual conflicts and to guarantee the well functioning of the international economic system, these...

The purpose of this paper is to investigate when subsidies for public transport are justified. We first theoretically identify the key parameters in determining the desirability of public transport subsidies. We then use a detailed numerical optimisation model, calibrated with data on...

In the first phase of the research project Nanotechnologies for tomorrow’s society (www.nanosoc.be), the research consortium explored a variety of futuristic visions or techno-scientific imaginaries. This exploration took the form a Policy Delphi, adapted to the particular objective of jointly...

The main purpose of this paper is twofold. First, the relationship between flow and speed is assessed by means of simulation. Second, the effectiveness of some queueing based traffic models with state dependency is tested by comparing their outcomes to the recorded simulation-based results. It...

This article presents a bivariate comparison of Flemish family and non-family firms, investigating differences with respect to CEO characteristics, strategy, management information systems, environment, financing issues, performance and growth. Several authors have indicated that observed...
