Some models are presented in this paper which extend the concept of measuring superefficiency to the useful case of variable returns-to-scales (VRS), thus enabling the ranking of efficient as well as inefficient units. Two models, namely the Universal Radial Model and the Universal Additive...

Die internationale Beachtung der Forschungsergebnisse in der Wirtschaftsinformatik hat in den letzten Jahren an Bedeutung gewonnen. Dabei wird dem kritischen Diskurs ein wachsender Stellenwert eingeräumt. Hier gilt es, den wissenschaftlichen Nachwuchs in der Konzeption und Durchführung der...

This paper analyses a large database on inter-firm R&D cooperation formed in the pharmaceutical biotechnology industry during the period 1985 - 1998. The results indicate that network size largely grows, whereas the density of the network declines during the periods. In the network analysis that...

Nowadays Russian government pays a lot of attention to solutions of the high energy intensive production system in the country. The key factors of low efficiency of regional energy saving programs is the lack of approved standards and algorithms in the area of energy audit. In practice, both...

There is widespread interest in estimating the number of hungry people in the world and trends in hunger. Current global counts rely on combining each country's total food balance with information on distribution patterns from household consumption expenditure surveys. Recent research has...

This paper summarizes the findings of an analysis among scientific infrastructure service providers. These service providers have been evaluated in regard to their potential services for the management of publication-related research data. By conducting a desk research and an online survey, we...

This paper explores the potentials of applying Space Syntax methodology to analyze the effects of urban configuration on cities' transport performance. The empirical analysis takes as a case study the Federal District (Brazil) and its 19 administrative regions considering its urban road systems...

This paper aims to provide an introduction to the current state of the art of EUROMOD, the European Union tax-benefit microsimulation model. It explains the original motivations for building a multi-country EU-wide model and summarises its current organisation. It provides an overview of EUROMOD...

In the microsimulation literature, it is still uncommon to test the statistical significance of results. In this paper we argue that this situation is both undesirable and unnecessary. Provided the parameters used in the microsimulation are exogenous, as is often the case in static...
