Nachfragefunktionen für die Produktionsfaktoren Arbeit und Kapital

Summary In this paper we present dynamic factor demand functions for labour and capital, and the underlying production function for the Austrian economy. Our approach is neoclassical. By definition, the production function is of the Cobb-Douglas type; experiments with a CES production function were not successful. Our empirical results look very plausible. The adjustement speeds, the output and price elasticities of both factor demand functions, as well as the parameters of the underlying production function are of a order of magnitude highly compatible with neoclassical theory.     

Installing successful factories in developing countries

A big mistake of MNCs in installing factories in developing countries is to set up production planning systems similar to those in their other factories. The best system is one that reflects the resources and goals of the particular facility.     

Policy rule Nash equilibria

Abstract.  We study how different types of instrument rules affect the outcome of a monetary policy game between the central bank and the private sector. Policy rules can be independent of output and a shock, functions of the shock, or functions of output. We rank the Nash equilibria generated by different types of policy rules according to the central bank's ex ante expected loss. If both players can condition on output, then the following is true: no equilibrium exists if the central bank cares much about output stability and little about price stability, and infinitely many equilibria exist otherwise. JEL classification: E52, E61
Equilibres à la Nash des règles de politique.  L'auteur étudie comment le choix de divers types de règles instrumentales a un effet sur le résultat d'un jeu de politique monétaire entre la banque centrale et le secteur privé. Les règles de politique peuvent être indépendantes de la production ou d'un choc, être fonction d'un choc ou de la production. On établit un ordre des équilibres à la Nash engendrés par ces divers types de règles de politique selon la taille des pertes anticipées ex ante par la banque centrale. Si les deux joueurs fondent leur comportement sur la production, il s'ensuit que — aucun équilibre n'existe si la banque centrale est très préoccupée par la stabilité du niveau de production et peu préoccupée de la stabilité des prix, et autrement, une infinité d'équilibres existent.     

Wissenschaftskommunikation 2.0?Science communication 2.0?

The key question of this article is: How is scholarly communication changing under the conditions of the online world? A lot of online media have developed especially for science communication. Their basic principle is multidimensional convergence: elements that once were strictly separated grow together and create new differences, in all dimensions of communication. The more this potential is used, the stronger the structural change of science communication emerges, which includes all communication areas and all components of the research process. The structural change is mainly expressed by seven tendencies of change: the pluralization of communication players, the globalization of communication space, the acceleration of communication processes, amongst others. These tendencies are characterized by their ambivalence and formability. For scientific journals these tendencies offer the chance to strengthen their role as the core of science communication. Hence, there are options for the actors.     

„Politische Kommunikation“: Kern und Rand des Begriffsverständnisses in der Fachgemeinschaft

Terms and concepts are both premises and results of research. Controversies about the basic concepts of a discipline prompt scientific advancement. The aim of this paper is not to put forward an authoritative definition of “political communication,” but—based on prototype semantics—rather to work out what the core of the understanding of this concept is within the scientific community, and what the margin. This is also a test for a method of analyzing the understanding of concepts in general. The basis is a dimensional analysis of the concept of “political communication,” in which a four-dimensional basic structure established by deduction was tested by means of a content analysis of textbook definitions. This leads to a tool for a factorial survey to empirically analyze students’ and lecturers’ understanding of this concept (n = 161). The findings were: At the heart of the understanding of the concept are communication participants deeply involved in the political system in a context of mass media communication. Differences in content and consequences of communication have no influence on the understanding of the concept, and the differences between students and lecturers are small. Comparisons between countries and longitudinal studies are possible on this basis.
