Price-volume relation in stocks: A multiple time series analysis on the Singapore market

We examine the price-volume relation in stocks using the multiple time series approach due to Tiao and Box (1981). This approach has the advantage of treating price and volume jointly and symmetrically (without enforcing the roles of input and output). It is free of the simultaneity bias in regression analysis and the unidirectional dynamics imposed by transfer function models. Empirical results show that there is implicit positive correlation between price and volume through their residuals. However, the results for the explicit lead and lag relations are mixed. The technical analysts' adage that volume often leads the trend of price is not supported. Nonetheless, the implicit relationship between price and volume confirms the usefulness of incorporating volume data to forecast future return. Our analysis shows that the multiple time series models outperform the univariate models in post-sample forecasts.     

Prevention versus Treatment under Precautionary Regulation: A Case Study of Groundwater Contamination under Uncertainty

Policy discussions on agricultural pollution problems characterize prevention as more cost effective and precautionary than ex post treatment. We derive conditions under which treatment alone is more cost effective in situations involving multiple sources of emissions, multiple sites affected, and a commonly used precautionary approach to uncertainty. We also show that a greater degree of precaution can result in less reliance on prevention. An empirical case study indicates that treatment alone is the most cost-effective means of dealing with nitrate in most Maryland community water system wells. The use of leaching prevention measures is restricted to the most intensive poultry producing areas. The incremental cost of precaution is substantial.     

Skilled maintenance work at British Telecom: findings from the Social Change and Economic Life Research Initiative

Here the author examines the relationship of technical change and job skills amongst maintenance workers in telecommunications in Britain. It demonstrates that there are significant variations within different areas of such maintenance work and strongly challenges the notion that such maintenance work is subject to a generic process of deskilling in the present era.     

Congestion games with load-dependent failures: Identical resources

We define a new class of games, congestion games with load-dependent failures (CGLFs). In a CGLF each player can choose a subset of a set of available resources in order to try and perform his task. We assume that the resources are identical but that players' benefits from successful completion of their tasks may differ. Each resource is associated with a cost of use and a failure probability which are load-dependent. Although CGLFs in general do not have a pure strategy Nash equilibrium, we prove the existence of a pure strategy Nash equilibrium in every CGLF with nondecreasing cost functions. Moreover, we present a polynomial time algorithm for computing such an equilibrium.     

Employment Patterns in Contemporary Retailing: Gender and Work in Five Supermarkets

This article examines trends in patterns of employment within contemporary retailing. It focuses upon five supermarkets in the Lancaster area. In each store the proportion of part-timers had increased during the 1980s and in four cases it stood at over 70 per cent in 1990. However, there were marked differences in the proportions of female full-time and part-time employees who were married. Management reported similar perceptions of the relative advantages and disadvantages of employing married women within their stores. These belief systems coexisted with radically divergent recruitment strategies by these managements. These variations were embedded within typical recruitment strategies in each of the firms examined.     

Problem formulation in industrial marketing research

Marketing research is achieving increasingly greater recognition in the industrial marketing field as one of the major tools to assist management in decision-making processes. Its position in consumer goods marketing has long been well established, and its use has been widespread. At the present time industrial marketing research is becoming more accepted as a normal part of marketing management whose efforts are directed to the industrial markets for goods and services.     

Current research in moral development as a decision support system

This paper argues that human beings possess the rational capabilities necessary to achieve the goal of more just and peaceable social orders, but that our educational institutions are failing in their responsibility to do what in fact can be done to produce graduates who make decisions in ways most likely to achieve this goal.Data compiled by us, consistent with other research, indicates that only a small percentage of the individuals graduating from universities and professional schools have developed the capacity for post-conventional moral reasoning.

Cross-cultural negotiations in the hospitality industry: the Japanese market

The growing importance of travel and tourism to the economy of the United Kingdom is widely acknowledged. The increasing contribution made by travellers from Japan to the income of this industry has also been acknowledged. The authors review the guidance given in the literature to those responsible for negotiations with representatives of the Japanese market and compare this with their own findings obtained from interviews at senior management level in London hotels for which the Japanese market represents a significant proportion of their business. It emerges that certain guidelines can be identified which will help managers in the hospitality industry prepare themselves for negotiations with the greater probability of a successful outcome.
