How we talk when we talk about nano: The future in laypeople's talk

Nanotechnology is an example of postnormal technoscience ‘in the making’: its concrete products and applications are currently only starting to trickle into the marketplace. In this paper I use nanotechnology as a case to examine how uncertain technoscientific futures are represented in lay talk. I engage with this question through a close analysis of focus group discussion around nanotechnology, describing the cultural and linguistic resources that participants draw upon in doing this, including personal experience and expertise, analogies and comparisons, and fiction and popular culture. These are, I suggest, the key discursive tools with which laypeople can weigh up and evaluate emerging technologies. However, I also argue that these are used flexibly to create different kinds of arguments in different conversational contexts, and use the example of nanotechnology as ‘the same’/’different’ to illustrate this. In concluding I reflect on the implications of these findings for scholars of public opinion and attitude and for those who frame policy on emerging and uncertain science and technology.     

The Credit Crunch and Insider Trading

This paper examines the behaviour and information content of insiders’ trades before and after the credit crunch and, in particular, examines the extent to which some insiders anticipated the market crash and took action to protect their positions. In part, the market crash was brought about by the excessive borrowing of financial institutions. Our results point to the view that a number of insiders, primarily directors, were aware that the excessive use of leverage by financial institutions would ultimately have a detrimental impact on the economy. These insiders acted by selling their shares prior to the market collapse and subsequently buying them back at a lower price. Supportive evidence for the above view is provided through both graphical evidence and regression analysis. In particular, we demonstrate a link between insider behaviour and the rapid decline in share values. Further evidence is also provided of a link between insider behaviour and future risk as measured by the CDS premium. In short, we argue that this selling was not motivated by liquidity or other contrarian strategies but was a result of understanding how higher levels of leverage and excessive trading in new risky derivatives could lead to higher levels of risk, an insight possessed only by a subset of insiders.     

From spending to understanding: Analyzing customers by their spending behavior

In customer segmentation, a common strategy is to use individual differences as a predictor of future behavior. Recent advances in data management in large financial institutions give an unprecedented and potentially powerful source of data for identifying such differences. We show that spending data can substantially help target the direct marketing of financial products, and constitutes new information, not captured by demographics. In particular, a systematic combination of this independent source and more traditional measures can enhance the predictive power of marketing research and improve the relationship with customers as illustrated in a direct mailing selection method which substantially raises response rates.

In a previous paper Khan and Fiorino analyzed four energy saving projects. They found that use of the Capital Asset Pricing model to account for risk implied that the projects’ required rates of return were less than the return on riskless assets. Effectively lie projects bad negative risk. These negatively with macro economic activity. The current paper has two objectives: (1) to show that cafes of negative risk are rare and unimportant, and (2) to show that the assumption of negative covariance between energy price and the level of economic activity is incorrect.     

Comparative Computer Approaches to Multi-Outlet Retail Site Location Decisions

This article explores alternative changes that could take place in the technology, methodology, and most importantly, the practice of locational decision-making, and is part of a larger scale project aimed at investigating the practical value of artificial intelligence (AI) techniques for strategic decision-making. The research involves comparing the effectiveness of a number of AI paradigms and modelling devices, both with each other and with more conventional computer models.     

Ethics in regulation

This paper was given as the opening address at the 13th Annual European Business Ethics Network Conference' held in Cambridge 12–14 September 2000. The Chairman of the Financial Services Authority, Howard Davies, first outlined the background to the present approach to financial regulation in the UK. He described the principle‐based regulatory regime which is now in the process of being implemented, and the role of rules, regulations and guidelines in making this effective. However, compliance is not sufficient; for the system to work there needs to be an ethical culture at the level of the organisation, and a commitment to integrity on the part of those who work in the sector. The Financial Services Authority aims to work with the industry to build individual and corporate responsibility.     

The impact of HR configuration on firm performance in Singapore: a resource-based explanation

This study investigates how the characteristics of a firm's human resource practices and processes (HRPPs) are associated with firm performance. The results found that the extent to which HRPPs can be substituted by information technology or codified in employee manuals, made them easy to be imitated and were therefore associated with an attenuation of the firm's financial performance. On the other hand, constant positive investments into a firm's HRPPs were associated with enhanced firm performance. No significant relationships were found between the embeddedness of HRPPs with information technology or the uniqueness of the firm's HRPPs and firm performance. The results are explained in terms of the resource-based view of the firm.     

Employee Movements from Audit Firms to Audit Clients

Regulators have expressed concerns about the “revolving door” between auditors and clients, whereby audit employees move directly from audit firms to audit clients (i.e., “direct alumni hires”). Regulators are concerned that these direct hires could compromise audit quality, partly because these employees could have previously audited their hiring company's financial statements. In contrast, we examine accounting and finance executives who move indirectly from audit firms to audit clients and who could not have previously audited the hiring company's financial statements (i.e., “indirect alumni hires”). We show that indirect hires occur more often than the direct hires that have concerned regulators. We predict and find that both direct and indirect alumni hires are associated with lower rates of executive turnover and audit firm turnover. However, there is no evidence that the reduced rates of executive turnover are explained by managerial entrenchment or that these hires are associated with lower audit quality. Overall, our findings suggest that direct and indirect employee movements from audit firms to audit clients are beneficial to executives, audit clients, and audit firms because they reduce the incidence of costly turnover.     

On additivity of tail comonotonic risks

ABSTRACT

As perceived from daily experience together with numerous empirical studies, the multivariate risks demonstrate a strong coherence in the extremal dependence structure especially over the course of financial turmoil or industrial accidents and outbreaks. Under this motivating paradigm, we show the universal asymptotic additivity under upper tail comonotonicity, as the probability level approaching to 1, for Value-at-Risk and Conditional Tail Expectation for a portfolio of fixed number of risks, in which each marginal risk could be any one having a finite endpoint or belonging to one of the three max domains of attraction. Our obtained results do not require the tail equivalence assumption as needed in the existing literature. This resolves a lasting problem in quantitative risk management and covers most distributions commonly encountered in practice.     

Union objectives and indexation externalities in a monopolistically competitive economy

This paper extends the literature on indexation externalities by analyzing equilibrium and efficient indexation in a unionized economy characterized by a monopolistically competitive goods market. The assumption that union objectives relate to both employment and the real wage implies that union indexation decisions are associated with a negative externality and, as a consequence, the equilibrium degree of indexation is inefficiently high. This feature is characteristic of both passive and activist policy environments.
