Deutsche Mark–Dollar Volatility: Intraday Activity Patterns, Macroeconomic Announcements, and Longer Run Dependencies

This paper provides a detailed characterization of the volatility in the deutsche mark–dollar foreign exchange market using an annual sample of five-minute returns. The approach captures the intraday activity patterns, the macroeconomic announcements, and the volatility persistence (ARCH) known from daily returns. The different features are separately quantified and shown to account for a substantial fraction of return variability, both at the intraday and daily level. The implications of the results for the interpretation of the fundamental "driving forces" behind the volatility process is also discussed.     

Assessing Benefits from Department of Health and National Health Service Research & Development

Public services in the UK are increasingly expected to account for their outputs and performance. This article describes a retrospective evaluation of the benefits from the R&D funded by a regional office of the NHS Executive. The methods adopted enabled the various elements of the region's R&D portfolio to be examined and provided a basis for the development of a plan for regular monitoring. The proposals for implementation are now also feeding into a debate as to how health services R&D might best be monitored nationally in a way that is compatible with the norms and practices of research in other contexts.     

Perceptions of the Ethical Work Climate and Covenantal Relationships

Employees perception of the existence of a covenantal relationship between themselves and their employer indicates that they believe there is a mutual commitment to shared values and the welfare of the other party in the relationship. Research suggests that these types of employment relationships have positive benefits for both employees and employers. There has been little research, however, on the factors that determine whether such relationships will develop and thrive.In this paper, we suggest that the organizations ethical work climate may be an important factor affecting employees perceptions about the nature of the relational contract between themselves and their employer. Specifically, we argue that work climates emphasizing benevolence and principle will be associated with covenantal relationships. Conversely, we believe that work climates emphasizing egoism will make it less likely that covenantal relationships will develop between an employer and employee.In order to test our hypotheses, we collected data from 194 employees of a large retail department store. The employees perceived their work climates in terms of principle (laws and professional codes) and benevolence, but to a lesser extent also believed that egoism (self interest) concerns characterized their climate. After controlling for demographic and job-related variables, we found (as expected) that measures of principled and benevolence climate were positively associated with covenantal relationships and that a measure of egoistic climate was negatively associated with covenantal relationships. In the final section of the paper, we discuss the implications of these findings for research and practice.     

Emotional arousal and entrepreneurial outcomes: Combining qualitative methods to elaborate theory

This qualitative study of innovators in the superyacht industry blends longitudinal content analysis with narrative case vignettes to extend nascent theorizing about the antecedents and consequences associated with the arousal of entrepreneurial emotion. The empirically grounded framework induced through our research offers two key theoretical elaborations. First, it extends the existing set of theorized antecedents by highlighting the overlooked roles played by dramatic performances (staged or improvised) and ambient conditions (project, actor and venue considerations). Second, it calls attention to the consequences of emotional arousal for such entrepreneurial outcomes as generating novel solutions to specific problems encountered during the creation process, developing innovative end products, and fostering a general context for innovation.     

WTO Dispute Settlement and the EU–US Mini Trade Wars: A Commentary on Fritz Breuss

Economic theory suggests that some of the trade remedies allowed by the WTO may lead away from liberal trade and impose costs on those that apply them. Breuss has provided evidence in the case of four EU-US mini-wars that the policy that created the trade conflict was not clearly in the economic interest of the offending country and that the sanctions imposed exacerbated rather than alleviated the problem. Breuss builds a case for compensation payments rather than trade sanctions for rule violations and for targeting of the recipients of those payments.If trade policy were a matter of economic rationality then this approach would be convincing. For better or worse, the trade rules are an unruly mix of economic, political and legal constructs. The commentary expands on this to explore the role of the dispute settlement process itself and the sanctions designed to give it teeth. The conclusion is that the economic calculations, while a good measure of the costs of legal or political decisions, are not central to the dispute settlement and sanctions processes. The dispute settlement process is also about preserving the balance of political advantage from negotiated rules and schedules, and the sanctions process is as much to do with preventing abuse as correcting it. So a full economic analysis would have to compare politically balanced alternative scenarios and the incorporate the effect of the threat of sanctions on government behavior.
