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...

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...

This paper attempts to quantify the impact of fragmentation on employment. Factor demand functions for labour and intermediates and mark up price equations derived from a Generalized Leontief cost function at industry level are estimated. Import prices and output prices influence the price of...

This paper describes interfuel substitution for coal, oil, gas and electricity at a level of 12 activities. We use cross section data in each activity for appliance technologies (heating/cooling, steam generation, industrial processes, motors and lighting/computing) to estimate fuel input demand...

Tourist demand is subject to considerable variations, a fact which aggravates the development of forecast models of sufficiently adequate accuracy. This study develops models that permit including most if not all factors of influence. To this end, due consideration was given to calendar effects...

This paper sets up a model of private consumption for selected EU countries with special emphasis on the consumption categories heating and transport. Sustainable consumption patterns require a "decoupling" of energy or materials use from satisfaction of consumers' needs and demands. Starting...
