This paper deals with the regularity problem in the Almost Ideal Demand System (AIDS) in terms of the boundedness of the budget shares within the [0,1] interval. The violation of "cointegration accounting" can be seen just as another consequence of irregularity. The discussion of modifications...

Gemäß der Preisstatistik der Europäischen Kommission waren die Kraftstoffpreise in Österreich durchwegs höher als in den Nachbarländern. Die Preisdifferenz kann Standorts- aber auch wettbewerbsbedingt sein. Die Wettbewerbsintensität beeinflußt nicht nur das Preisniveau, sondern auch die...

We analyse cross-border co-operation of Austrian firms with CEEC partners. Firm size, previous experience with co-operation and depth of integration with the most important partner are more important determinants of co-operation than distance to the closest potential partner. Firms with...

This paper analyses the co-operation activities of small Austrian firms with the CEEC and compares them to those of larger firms. Small firms are less likely to engage in cross-border co-operation than larger firms, more likely to co-operate in ownership based forms of co-operation but less...

We explore differences between two measurement concepts of worker flows widely used in the literature referred to as the turnover and reallocation concepts. We find that measuring worker flows by the turnover concept leads to substantially (about 5 percent of total employment) higher worker flow...

This paper analyses the effects of previous enlargements of the European Union on the regional structure of production. Focusing on regional development five years before and seven years after integration, we find relatively small and heterogeneous effects. For the addition of Greece a robust...

Two recent studies published in "Perspektiven der Wirtschaftspolitik" are used to discuss methods to develop bibliometric analyses and rankings of economic research institutions. According to them, standardisation methods using the number of staff or university graduates may have a crucial...
