Queues and Hierarchies

This paper examines the optimal structure of hierarchies when workers differ in the range of tasks they can perform. A hierarchical system may reduce costs by allowing most tasks to be handled by unskilled workers. This may however increase delay for those tasks which must pass through several layers before reaching the appropriate level. The paper characterises an optimal hierarchy when such a trade-off exists.     

Toward global checks and balances

The rapid growth and importance of intergovernmental coordination in the regulation of markets, transportation and communication, the environment, and national security poses numerous challenges for democratic accountability within participating states. Direct public participation in the intergovernmental regulatory bodies is generally modest or absent. Information regarding their deliberations is limited. And the multiple oversight mechanisms and supervisory processes that exist at the domestic level of developed democracies that can scrutinize intergovernmental regulatory decisions tend to be lacking. This lack of accountability raises legitimacy concerns, the most prominent of which is the fear executive branch officials will delegate controversial policy decisions to intergovernmental bodies in order to escape democratic deliberation. In this paper we survey the ways that different review venues (other international institutions and national courts) are attempting to cope with these accountability related issues: we argue that national courts may prove to be the most effective venue for promoting democratic accountability. This is not because they are more reliably representative of their domestic constituency or possess a more cosmopolitan perspective than the bodies whose decisions they are reviewing. Rather their relative advantage lies in: (1) the increasing acceptance on the part of domestic courts that inter-judicial coordination is a prerequisite for their continued ability to fulfill their judicial review function; and (2) the visibility that the decisions of these courts possess. Acting together these two forces have the potential to foster greater transparency and public deliberation than most rival venues.

Does Chatter Matter? The Impact of User-Generated Content on Music Sales

The Internet has enabled a new era of user-generated content, threatening the hegemony of traditional content generators as the primary sources of “legitimate” information. In this study, we examine the usefulness of such content, consisting of data from blogs and social networking sites, in predicting sales in the music industry. We track changes in online chatter for a sample of 108 albums for four weeks before and after their release dates. We identify the significance of variables on the observation date in predicting future album unit sales one, two, and three weeks ahead. Our findings are that future sales are positively correlated with (a) the volume of blog posts about an album, and (b) traditional factors such as whether the album is released by a major label and reviews from mainstream sources like Rolling Stone. More generally, the study provides some preliminary answers for marketing managers interested in assessing the relative importance of the burgeoning number of “Web 2.0” information metrics that are becoming available on the Internet. The study also provides a framework for thinking about when user-generated content influences decision making.     

Strategic choice during economic crisis: Domestic market position,organizational capabilities and export flexibility

This study examines how sudden shrinkage of domestic demand affects firm-level export performance. Using the Asian economic crisis as a natural experiment, we show that while the industrial organization (IO) economics and resource-based view (RBV) apply well in the pre-crisis period, the real options perspective does a better job in explaining firms’ efforts to increase exports in the post-crisis period. Specifically, using a real options perspective, we show how sudden change in domestic demand provides benefits to those firms that have invested in flexible capabilities while those firms that are locked in with inflexible resources fail to change. We find that the positive relationship between a firm's domestic market position and export intensity becomes stronger in the post-crisis than the pre-crisis period. Further, we find a positive relationship between non-location-bound flexible capabilities such as R&D and export intensity and a negative relationship between location-bound inflexible capabilities such as advertising and export intensity. These relationships become more pronounced in the post-crisis period.     

Consumers,cars and communities: the challenge of sustainability

The huge subsidization of sprawling development and the unbridled use of the private automobile needs to be brought to the forefront of public policy debate, not left to the excesses of the market‐place. To do this we need citizens‐in‐the‐community, not consumers‐in‐the‐market. The present costly and unsustainable situation of our human settlements is a result of a profound failure in public policy; a failure that resulted when we left the fate of our human settlements to the vagaries of the market‐place. We can no longer rely on the present subsidized, distorted, market‐place system approach to designing, building and operating our human settlements. The consequences have been disastrous for human welfare, health and safety, and the natural environment upon which all life depends.     

REVERSE LOGISTICS: THE RELATIONSHIP BETWEEN RESOURCE COMMITMENT AND PROGRAM PERFORMANCE

In response to increasing volumes of returned products, firms are establishing programs to guide the reversal of flows in the supply chain, i.e., reverse logistics. With reverse logistics programs firms seek cost savings and efficiencies related to reclamation, redistribution, and disposal of products returned “upstream” to the retailer or manufacturer. This paper reports on a recent survey of electronics catalog retailers regarding reverse logistics program involvement. In addition to creating a profile of current reverse logistics activities in an industry characterized by high volumes of returns, the research also examines the relationship between investment in reverse logistics related resources and reverse logistics program performance.     

Project Appraisal and Capital Investment Decision Making in the Scottish Water Industry

Restructuring the Scottish water industry has changed the way in which both project appraisal and capital investment decisions are performed. This article examines the project appraisal and subsequent capital investment decision in the case of a reed bed sewage treatment scheme which is compared with a more traditional scheme. Although the capital profiles of the schemes are similar there are major differences in the revenue costs. In addition, there are potential public benefits to the reed bed scheme. A comparison is made of management mechanisms in the pre-1996 water industry with that of restructured water authorities. In the pre-1996 water industry, local authorities had a broad remit which encouraged them to value these factors, in effect an implicit social account. The creation of water authorities with narrow remits and specific performance measures, constructed a framework that does not support the integration of social accounts into the decision making process. The paper demonstrates that investment appraisal is a product of the institutional framework in which the decisions are made. As that framework changes, mechanisms and measures of accountability shift in parallel.
