This paper concerns the problem of agent trust in an electronic market place. We maintain that agent trust involves making decisions under uncertainty and therefore the phenomenon should be modelled probabilistically. We therefore propose a probabilistic framework that models agent interactions as a Hidden Markov Model (HMM). The observations of the HMM are the interaction outcomes and the hidden state is the underlying probability of a good outcome. The task of deciding whether to interact with another agent reduces to probabilistic inference of the current state of that agent given all previous interaction outcomes. The model is extended to include a probabilistic reputation system which involves agents gathering opinions about other agents and fusing them with their own beliefs. Our system is fully probabilistic and hence delivers the following improvements with respect to previous work: (a) the model assumptions are faithfully translated into algorithms; our system is optimal under those assumptions, (b) It can account for agents whose behaviour is not static with time (c) it can estimate the rate with which an agent's behaviour changes. The system is shown to significantly outperform previous state-of-the-art methods in several numerical experiments.

Reputation is a signalling device that serves as a proxy for the quality of a firm’s products, strategies and employees relative to its competitors, when communicating with clients and other stakeholders. It is especially important for professional service firms because of the complex and intangible nature of their service and because of the advantages it confers in the market for high-quality professional staff. This paper extends and refines existing research on reputation which shows positive returns to reputation for professional service firms. We use different rankings of the top 50 law firms in the UK to measure reputation and examine their relationship with financial performance as expressed in firm revenue and profits. We find positive but diminishing returns to reputation even within this group and we find a stronger relationship between reputation and profits than fee income. We conclude that reputation may be an important source of competitive advantage for leading firms but it seems to offer little leverage for others. If these results are generalizable across other professional sectors this raises the question of how the majority of firms can differentiate themselves.

The article focuses on the Trade Marks Regulations 2004, which came into force on May 5, 2004. Regulation 7 repeals s 5(3)(b) and amends s 10(3) of the Trade Marks Act 1994, implementing the decision of the European Court of Justice in Davidoff & Cie SA and Zino Davidoff SA v Gofkid Ltd., which was then confirmed in Adidas-Salomon AG and Adidas Benelux BV v Fitnessworld Trading Ltd. The orthodox definition of the primary and proper function of a trademark is that it is to identify the origin or ownership of the goods to which the mark is affixed. As society has changed so too have the functions of the trademark. Due to increased affluence and the growth of the consumer society, some trademarks may now have achieved the status of being a symbol of desire in their own right.

This paper first analyses the Performance Related Pay (PRP) schemes developed from 1992/3 to 2002/3 in a large Business School in England and then the School’s mission and strategic objectives in that period. The PRP schemes changed to include more specific performance indicators and these were increasingly linked to the objectives. The School’s resources allocated to PRP increased from £44,000 in 1992/93 to £355,000 in 2002/3 and from 1.08% in 1995/96 to 2.37% of the School’s income in 2002/3. As well as examining the changing strategic objectives and PRP schemes, the paper charts the development of the School’s reputation and resources and the role which staff motivation via PRP played at different stages. The paper concludes that the PRP scheme was at its most effective when it was clearly linked with the School’s strategic objectives, but that the relationship between objectives and motivation may be more complex than apparent from this study. Although the PRP scheme under consideration also applies to academic related staff, this paper concentrates on the effect on academic staff.

Werner Sombart (1863-1941) was a famous and controversial social scientist in Germany during the early 20th century. Highly influential, his work and reputation have been indelibly tainted by his embrace of National Socialism in the last decade of his life. Although Sombart left an enormous opus spanning disciplinary boundaries, the scholarly assessment of and intellectual reaction to his work inside and outside of Germany is divided, and ambivalent. Best known for his analyses of capitalism - his essay "Why is There No Socialism in the United States?" remains a classic - Sombart consistently responded to the social and political developments that have shaped the 20th century. This collection provides a representative sampling of those portions of Sombart's work that have stood the test of time. The volume opens with a substantial introduction by the editors reviewing Sombart's life and career, the evolution of his major intellectual concerns, his relation to Marx and Weber, and his political affiliation with the Nazis. Their selection of texts emphasizes areas of his economic and cultural thought that remain relevant to intellectual trends in the social sciences, particularly those trends that seek a more broadly based, cross-disciplinary approach to the relationship of culture and economics. Sombart's writings on capitalism are represented by essays on the nature and origin of the market system and the diversity of its actors and motives among the bourgeoisie and the proletariat. Also included is an excerpt from Sombart's controversial volume "The Jews and Modern Capitalism" exploring the widely perceived relation between economic life and Judaism as a religion. In essays on the economics of cultural processes, Sombart's comprehensive and expansive idea of cultural science yields remarkable and prophetic insights into the nature of urbanism, luxury consumption, fashion and the cultural secularization of love. The volume's final section consists of Sombart's reflections on the social influences of technology, the economic life of the future, and on socialism, including the influential essay "Why is There No Socialism in the United States?". Encapsulating the most valuable aspects of his work, this study provides clear demonstration of Sombart's sense for fine cultural distinctions and broad cultural developments and the predictive power of his analyses. It should be of interest to sociologists, economists, political scientists and specialists in cultural studies.

Purpose – The purpose of this paper is to examine the state of knowledge management (KM) in the energy sector and more broadly, and consider future directions for research and practice. Design/methodology/approach – The paper reviews the literature on KM and the practice of KM as relevant to the energy sector. Findings – There are many examples of good practice in KM in the sector, and some organisations, especially in the oil industry, are seen as leaders in KM practice. However, other organisations have yet to embark on explicit KM initiatives or projects at all. In addition, some parts of the energy sector discuss KM without any reference to the more general KM literature. Originality/value – Although some parts of the energy sector have justifiably earned a good reputation for KM, other parts are completely unaware of the field, as is apparent from the literature. This review helps to raise awareness and guide future work.

Extant research on the impact of privatization in the Central Europe (CE) region has focused on improvements in efficiency and the nature of cost-based advantages. This study argues that the development of a vibrant privatized sector requires attention to the broader resource configurations of domestic enterprises. Empirical research was conducted on a large sample of firms in Poland, Hungary and Slovenia. Foreign investment was found to significantly impact on resource accumulation with implications for the development of strategic capabilities and competitive advantage. Foreign direct investment is an effective vehicle for the transfer of financial resources, reputation and new brands but not organizational capabilities. In terms of practice, this study demonstrates the important role of outside investment in the development of a firm's resource base (Frydman et al. 1999). Companies can gain a competitive advantage in their domestic markets through gaining access to the resources of foreign investors.

The stock market response to corporate scandals and the use of the internet by pressure groups have sensitized boards to the risk of reputation loss. Particularly at risk are companies using corporate brands whose fame and spread makes them particularly vulnerable. This study looks at these and other pressures on branding and investigates if and how leading companies have responded in the deployment of their brand portfolios. A repeat audit of the use of brand portfolios by leading companies using exactly the same method used over a decade ago reveals much change. Brand structures of the 20 companies investigated have indeed changed but not uniformly in extent or direction.
