Privatizing Australian Airports: Ownership, Divestment and Financial Performance

This article addresses the performance of the three largest Australian airports following their privatization. The airports represent cases of divestment of government business enterprises into privately-owned businesses each with differing ownership arrangements. The performances of the privatized airports are considered using financial data obtained from general purpose financial reports of the entities. There are significant implications for future divestment policies, including the value of divestment as a policy response in uncompetitive environments, the use of particular infrastructure investment models, and the nature of the linkage between ownership structure and financial performance.     

Identifying Technology Spillovers and Product Market Rivalry

The impact of R&D on growth through spillovers has been a major topic of economic research over the last thirty years. A central problem in the literature is that firm performance is affected by two countervailing “spillovers” : a positive effect from technology (knowledge) spillovers and a negative business stealing effects from product market rivals. We develop a general framework incorporating these two types of spillovers and implement this model using measures of a firm's position in technology space and productmarket space. Using panel data on U.S. firms, we show that technology spillovers quantitatively dominate, so that the gross social returns to R&D are at least twice as high as the private returns. We identify the causal effect of R&D spillovers by using changes in federal and state tax incentives for R&D. We also find that smaller firms generate lower social returns to R&D because they operate more in technological niches. Finally, we detail the desirable properties of an ideal spillover measure and how existing approaches, including our new Mahalanobis measure, compare to these criteria.     

An examination of the ISO 9001:2000 standard and its influence on the integration of management systems

Abstract

Analysis of the literature and examination of the various models of integration and testing in the field, have revealed five key issues relating to management system integration. This paper examines the recently published ISO 9001 : 2000 quality management system standard to see how it addresses these issues, under the headings of compatibility, scope and organizational culture. The examination reveals that while compatibility with the ISO 14001 and OHSAS 18001 standards has been improved in some areas, a different approach and model of a management system has been used. The paper suggests that differences in the scope of the standards are also likely to give rise to different sub-cultures which will hinder integration, and scope and culture are more important than compatibility. This leads the authors to conclude that new models of integration should be based on an approach and definitions which can be used in any management system, as well as an integrated one. Models of an integrated management system should also emphasize the need for no significant differences in the scope of the integrated systems, and a strong culture which supports the main requirements of TQM.     

The value of rescheduling functionality within standard MRP packages

One of the basic functions of an MRP system is to issue rescheduling messages that urge the planner tospeed up or slow down open orders. It seems in practice that these messages are not used at all by planners. This is mostly due to the inaccuracy of MRP, that more or less ignores safety time, safety stocks and lotsize flexibility in the calculation of reschedule-in messages. Reschedule-out messages are usually ignored because planners do not see the value of the message. Other reasons for not adhering to rescheduling messages are a lack of maintenance of MRP parameters or simply the wrong use of the MRP function. In the future, MRP rescheduling functionality will be used even less than today, due to the changing role of MRP within the planning framework. With the uprise of finite capacity scheduling packages, MRP is being pushed one level upward in the planning hierarchy. This means that rescheduling functionalities for the short term will become completely obsolete in MRP systems.     

Modeling Imbalanced Economic Recovery Following a Natural Disaster Using Input‐Output Analysis

Input‐output analysis is frequently used in studies of large‐scale weather‐related (e.g., Hurricanes and flooding) disruption of a regional economy. The economy after a sudden catastrophe shows a multitude of imbalances with respect to demand and production and may take months or years to recover. However, there is no consensus about how the economy recovers. This article presents a theoretical route map for imbalanced economic recovery called dynamic inequalities. Subsequently, it is applied to a hypothetical postdisaster economic scenario of flooding in London around the year 2020 to assess the influence of future shocks to a regional economy and suggest adaptation measures. Economic projections are produced by a macro econometric model and used as baseline conditions. The results suggest that London's economy would recover over approximately 70 months by applying a proportional rationing scheme under the assumption of initial 50% labor loss (with full recovery in six months), 40% initial loss to service sectors, and 10–30% initial loss to other sectors. The results also suggest that imbalance will be the norm during the postdisaster period of economic recovery even though balance may occur temporarily. Model sensitivity analysis suggests that a proportional rationing scheme may be an effective strategy to apply during postdisaster economic reconstruction, and that policies in transportation recovery and in health care are essential for effective postdisaster economic recovery.     

Improving the Quality of Staff and Participant Interaction in an Acquired Brain Injury Organization

Weekly observations of direct-care staff in a facility for persons with brain injury yielded less than optimal interactional style with facility residents. Following an observational baseline, staff were asked to self-rate a 15-min video sample of their interaction behavior with participants on their unit. They were then asked to compare their self-ratings to those of a supervisor, as well as view a video exemplar of appropriate positive interaction behavior. Elements of their interactional style were highlighted and specific feedback was provided on how to improve their performance. Interaction style was then reevaluated via an unobtrusive observer and yielded positive gains for all participants. Subsequent on-the-job feedback sustained performance gains.     

Temporary Work,Underemployment and Workplace Accommodations: Relationship to Well‐being for Workers with Disabilities

This study examines whether employment status and workplace accommodations are associated with perceived well‐being among workers with disabilities. Data from the 2006 Participation and Activity Limitation Survey conducted by Statistics Canada were used to test the relationship between employment status, receipt of workplace accommodations and well‐being. Findings indicated that fully utilized permanent employees showed greater life satisfaction and less perceived disability‐related discrimination than either temporary workers or permanent workers who were underemployed. These findings support the theory that inadequate employment is associated with deleterious effects on employee well‐being due to inferior need fulfilment and reduced social status. Workplace accommodations were associated with higher levels of well‐being for all workers with disabilities and helped to mitigate the negative effects of temporary status and underemployment. These findings supported the theoretical extension of main effect and buffering models of workplace stress to the prediction of perceived workplace discrimination.     

The contingent nature of best practices in national competitiveness: The case of American and Japanese innovation processes

We propose that the differences in competitiveness of companies from different countries is not just a question of the adoption of ‘better’ management models, as conventional wisdom would have us believe; rather, we contend that national competitiveness can change radically over time without significant changes in management practices. Contrary to much of the management literature we hold that changes in the global business environment often determine to a large degree the competitiveness of companies. Based on our assumptions we offer four specific lessons of how companies can increase their competitiveness within the constraints of the socio-cultural context in which they operate.
