Performance measurement in global governance: Ranking and the politics of variability

Abstract: The past thirty years have witnessed the spread of rankings, ratings and league tables as governance technologies which aim to regulate the provision of public goods by means of market pressures. This paper examines the process of company analysis underlying the production of a ranking known as the Access to Medicine Index. We conceptualize the Index as a “regulatory ranking” with the explicit mission of addressing a perceived regulatory gap and market failure: the lack of access to medicine in the Global South. The Index, which ranks the world's largest pharmaceutical companies with regards to their access to medicine policies and practices, aspires to help address the problem of access to medicine through stakeholder consultation, transparency and competition. This study unbundles the epistemic work underlying the performance measurement process leading to the creation of the Index. We trace how the goal of stakeholder consensus, the need to project objectivity and the aspiration to govern through competition shape analysts' epistemic work. We discuss how through notions such as “the good distribution” and “aspirational indicators”, performance measurement and ranking become entangled in a “politics of variability” whereby company data need to be variably interpreted in order to optimise the possibilities of intervening in companies through competitive pressures, while at the same time complying with the imperatives to remain in the space of perceived stakeholder consensus and to provide a faithful representation of companies performance to inform public debates. We reflect on the challenges posed by these analysis processes for the regulatory aspirations of the ranking.

Virtual communities: A marketing perspective

Abstract: Increasingly, consumers interact through the Internet to share their knowledge, experiences, and opinions. Consequently, 'word-of-mouse' has become a significant market force that influences consumer decision-making. On the basis of extensive quantitative and qualitative research, the authors sketch how consumers make use of virtual communities as social and information networks, and how this affects their decision-making processes. We present three studies that address (i) determinants and effects of virtual community influence on the consumer decision process; (ii) virtual community participation patterns; and (iii) discussion practices of the most active community members. Key implications for managers, marketers, and market researchers are discussed.

Real Options and Strategic Investment Decisions: Can They Be of Use to Scholars?

Abstract: Executive Overview Real options (RO) analysis has been of growing interest to the academic community as a promising approach to supporting investment decisions under uncertainty. In this article we examine an applied investment decision in the telecommunications industry to highlight the main benefits associated with using real options. The paper then discusses the theoretical issues raised by real options. Specifically, we examine two research streams to explain how real options contributes to a theoretical understanding of strategic management, and to better understand the gap between theory and practice of real options. Finally, we lay out an agenda for future research.

Fast and Slow Informed Trading

Abstract: This paper develops a model in which traders receive a stream of private signals, and differ in their information processing speed. In equilibrium, the fast traders (FTs) quickly reveal a large fraction of their information, and generate most of the volume, volatility and profits in the market. If a FT is averse to holding inventory, his optimal strategy changes considerably as his aversion crosses a threshold. He no longer takes long-term bets on the asset value, gets most of his profits in cash, and generates a "hot potato" effect: after trading on information, the FT quickly unloads part of his inventory to slower traders. The results match evidence about high frequency traders.
