Monetary policy in a Union of 27: Enlargement and reform options

It is to be expected that by early 2006 the European monetary union will be enlarged by up to 10 countries. This poses the question as to whether the current decision-making structure in the common central bank is adequate for such a large membership. Not only will such a large number of national representatives impair the efficiency of decision-making, but monetary policy will have to deal with a much more heterogenous group of members. The following article addresses the problem of enlargement and discusses reform options for the central bank.     

New product adoption in social networks: Why direction matters

Marketing managers and researchers generally agree that analyzing data from social networks and using them to influence consumers' purchase decisions are useful strategies. However, not all social network data may identify the most influential customers. This empirical study of more than 300 students reveals the low explanatory power of friendship networks (e.g., Facebook) and undirected-advice networks (e.g., LinkedIn). Only directed-advice networks (e.g., Google +) clearly identify influential consumers. In addition, the results challenge conventional wisdom that firms should target advisers assuming that they have the strongest influence on new product adoption. This study contradicts this common assumption and reveals that structural equivalence drives product adoption more than cohesion because advisees' adoption pressures advisers to purchase the product as well. Finally, the study shows the value of social network data beyond the traditional ego-centric psychographic metrics, such as innovativeness or opinion leadership.     

Public management reform in Denmark

Abstract

This article discusses public management reform in Denmark. First, the institutional features of the Danish public sector are introduced. Danish ministries enjoy a considerable amount of autonomy that makes central co-ordinated public management reform challenging. The second part of the article outlines the contents of public management reform and provides an overview of the major reform initiatives of the last three governments. Denmark's reforms are characterized as a mixture of strategies for modernization and marketization, but with most emphasis on the former rather than the latter. Together with successive governments, the Danish Ministry of Finance has argued strongly for efficiency, economy and effectiveness as key values and they have been institutionalized in modernization efforts. Denmark should now be considered a country where NPM reforms have taken a firm hold.     

Welfare and Integration

This article argues that the terms‐of‐trade and volume‐of‐trade taxonomy from the theory of tariffs constitutes an attractive alternative to Viner's trade diversion and creation effects for the analysis of preferential trading arrangements. In applications of the alternative approach, the article establishes that results by Lipsey and Riezman on large versus small preunion trade flows for choice of partners are not ‘contradictory’ and that under some conditions a small country's optimal strategy is to seek membership of multiple free‐trade areas.     

Responsibility in the interconnected economy

This article seeks to establish a link between the field of business ethics and information ethics by exploring the connection between responsibility and the Internet from an economic perspective. This link finds its expression in the moral theory of Discourse Ethics as suggested by German philosophers such as Juergen Habermas and Karl‐Otto Apel. The term responsibility points in the direction of communication and therefore leads easily to discourse ethics. The economy in general and most economic practices also seem to be intimately linked to questions of responsibility. The growing spread and importance of the Internet poses new challenges and problems but also creates new possibilities for ethics as well as for the economy. Here several of these new developments are analysed and their impact on ethics as well as economy assessed. Consequences for the use and development of information technology are considered.
