Some Challenges for Reformers and Architects

In these brief concluding remarks, I confine myself to a few reflections on some of the themes that have been broached today, without much reference to individual authors or comments, as it would be impossible to summarize everything that has been said at this conference about the new architecture of the international monetary system.     

Einige Bemerkungen zur Theorie der Planwirtschaft

Industry restructuring and regulation: Building a base for sustainable growth - lessons from Latin America

The potential for economic growth of nations is related to the state of their infrastructure. In this connection, it has been estimated that one percent growth in GDP requires an investment of one percent of GDP in energy, transportation, telecommunications, and water and sanitation infrastructure.     

Heterogeneity, returns to scale, and collective action

Abstract .  I analyze the effects of resource inequality and valuation heterogeneity on the provision of public goods with increasing or decreasing returns to scale in production. The existing literature typically takes the agents' characteristics as given and known to the researcher. In contrast, this paper compares collective action provision across groups of agents with resources and valuations for the public good drawn from different known joint distributions. Specifically, I characterize the expected equilibrium public good level as function of various distributional properties and moments. A resource-valuation distribution that first-order stochastically dominates another distribution always results in higher expected public good provision level, independent of the production technology. With decreasing returns to scale in the public good production, higher resource inequality results in higher expected provision. With increasing returns the same result holds when the mean resource level is relatively low, but expected provision decreases in inequality when the mean resource level is high. A parallel result holds for agents' valuations.     

CONSTRUCTING IMPACT FACTORS TO MEASURE THE INFLUENCE OF SUPPLY CHAIN MANAGEMENT AND LOGISTICS JOURNALS

Data from ten supply chain management and logistics journals are combined with data from the ISI Web of Science database to develop a series of impact factors. The resulting constructed impact factors provide a context for comparing and ranking leading academic supply chain management and logistics journals. They also provide an objective way of comparing the relative influence of supply chain management and logistics journals, as well as a platform for comparing their influence with that of journals in more general fields like management and business.     

Im Osten was Neues? Ein Beitrag zur Standortbestimmung der Kommunikations- und Medienwissenschaft

The aim of this article is to systematically describe and evaluate the foundation and extension of new study programs in communication and media science, and to develop further perspectives for the field. By means of a survey, the boom of programs in communication and media science at German universities is described. The various causes for this boom are not only found in the development of the media branch but also in the new (and perhaps questionable) responsibilities of university education that are subsumed under the concept of »media competence«. The article discusses the actual situation of the field against the background of the already existing debate about its self-conception. It names dimensions of the problem and develops consequences for the necessary structuring of the expanding university discipline of »communication and media science«. For the structuring, an intensified theoretical reflection about the subjects of the field, its methods, and the disassociation from neighbouring fields (still) seem to be important.
