Der US-Dollar als Leitwährung – alternativlos?

The importance of the industrialized countries – including the USA – for world production has been declining for a long time. By contrast, China’s share in particular has increased significantly. Nevertheless, the US dollar has largely fulfilled the criteria for a leading currency function so far, even if this is increasingly criticised due to the protectionist rhetoric of the US. Accordingly, central banks worldwide hold their reserves primarily in US dollars and transactions are largely conducted in US currency. This position brings great advantages–such as making it easier for the US to monitor and enforce sanctions, among other things–and therefore great incentives for the US to maintain its position as the leading currency. Whether other currencies, especially the renminbi, will be able to fulfil the lead currency function is questionable. Similarly, it does not seem realistic that market participants will be able to engage in a global currency.     

Public Professional Accountability: A Conditional Approach

In the past decades, profession(al)s have increasingly been called to account. Several authors have reported that this increased public professional accountability, in the form of showing that professional conduct meets predefined standards or rules, has had severe negative consequences for professionals, their clients and society, and call for ‘intelligent’ forms of accountability; forms of accountability that may inform a wider public about professional conduct but do not harm it. In this paper, we propose a form of ‘intelligent’ public professional accountability. Taking Freidson’s (Professionalism. The third logic, Polity Press, Cambridge, 2001) notion of institutional ethics as a point of departure, we develop a form of accountability that seeks to account for the conditions required for professional conduct. The paper first discusses the current ‘dilemma of professional accountability,’ describes ‘ideal-type professional conduct’ and goes into the conditions it requires. Next, it shows what accounting for these conditions entails and that this form of accountability fits the criteria for intelligent accountability, as set by O’Neill (in: Morris and Vines (eds.) Capital failure: rebuilding trust in financial services, Oxford University Press, Oxford, 2014).     

Conceptualization and Integration of Marketing Intelligence: The Case of an Industrial Manufacturer

Purpose: The primary goal of this article was to conceptualize a systematic marketing intelligence process for industrial manufacturers because, up until now, such concepts have only been focused on consumer goods settings. Hence, this article investigates how marketing intelligence activities are developed and managed effectively in industrial markets.

Methodology/approach: The authors conducted a case study of Maschinenfabrik Reinhausen, a German based manufacturer of regulation technology for power transformers.

Findings: We found that a systematic marketing intelligence process should be based on the resource- and market-based view of strategy as well as on the market orientation construct. When implementing marketing intelligence, the integration of the sales force within the whole process is the crucial lever for an industrial company. The formalization of the process is necessary to ensure its continuity and acceptance; however, the varying intensity allows the necessary flexibility of the process.

Research implications: The constraints of the decisive process steps of marketing intelligence have to be further enhanced for industrial markets. It is important to find out how the integration of the sales force can best be designed to incorporate reward systems and motivation structures, and how to establish a corporate marketing-minded culture throughout the organization.

Practical implications: The important steps for a well implemented marketing intelligence process are a preparation phase, followed by the gathering, analysis, and dissemination of information. This article highlights the success factors for each process step. Above all, managerial and organizational commitment is necessary for the implementation of the whole process.

Originality/value/contribution: By focusing on the industrial manufacturing business, this study provides deep insights into a neglected area of research. Light needs to be shed on marketing intelligence in industrial markets, where the lack of traditional market research has to be compensated.
