Dynamic Relationships in the Market for Ocean Grain Freighting Services

A vector autoregressive model containing ocean grain freight rates, grain shipments, idled tonnage, new carrier deliveries and fuel prices is used to evaluate dynamic linkages in the ocean grain transport market. Dynamic relationships are of particular importance in ocean freighting months because freighting services are often contracted several months before shipment. In addition, such markets may be slow to adjust to shocks because of significant short-run fixities in shipping services. Ocean grain freight rates are found to be responsive to fuel prices and new ship deliveries, but are not affected by demand shocks. Ship idling rates are found to be sensitive to fuel prices, grain shipments and freight rates. Significant adjustment lags are revealed.     

Asymptotic analysis for optimal investment and consumption with transaction costs

We consider an agent who invests in a stock and a money market and consumes in order to maximize the utility of consumption over an infinite planning horizon in the presence of a proportional transaction cost . The utility function is of the form U(c) = c^1-p/(1-p) for p > 0, . We provide a heuristic and a rigorous derivation of the asymptotic expansion of the value function in powers of , and we also obtain asymptotic results on the boundary of the no-trade region.Received: July 2003, Mathematics Subject Classification (1991): 90A09, 60H30, 60G44JEL Classification: G13Work supported by the National Science Foundation under grants DMS-0103814 and DMS-0139911.     

A Test of a Buying Rule for "Underpriced" Apartment Buildings

Apartment-building repeat-sales data are used to test a trading rule. Property values are estimated through regression; if the actual price is less than the estimated value, the property may be "undervalued." Returns are calculated for these "undervalued" properties and adjusted for risk using the Sharpe ratio. A test is done of whether these ratios are significantly different for different portfolios. The "undervalued" properties have higher appreciation returns, but once these are adjusted for risk, the differences in returns are not significant. The paper contributes to the real estate efficiency literature and suggests a workable method for comparing the performance of real estate portfolios on a risk-adjusted basis.     

Value creation and business models: Refocusing the intellectual capital debate

There is currently significant debate worldwide regarding business reporting. The concept of the ‘business model’ has entered into the discourse, as has the concept of ‘integrated reporting’, adding to the established debate regarding accounting for intangible assets and, more generally, intellectual capital (IC). Despite the tradition of extensive interdisciplinary borrowing in accounting, relevant literatures on business models and on modern managerial perspectives on competitive advantage have, to date, largely been ignored within the accounting literature. The main contribution of this conceptual paper is to identify and discuss the key features of these literature strands and their linkage to contemporary debates on narrative reporting. These conceptual linkages between IC, value creation and business models are illustrated by means of interview evidence from eleven company cases. It is concluded that the business model concept offers a powerful overarching concept within which to refocus the IC debate. The concept is holistic, multi-level, boundary-spanning and dynamic. The analysis supports the current calls for integrated disclosure around the central business model story. Suggestions for future research are offered.     

Divining directions for development: a cooperative industry–government–public sector research approach to establishing R&D priorities

This paper discusses the limitations of many fiscal and related methods of encouraging increases in R&D as a tool for establishing research priorities. It suggests that any 'national' rather than industry–specific approach is likely to be ineffective in stimulating the R&D needed for the development of all industries. This is particularly the case in countries such as Australia and New Zealand where many decisions about R&D investments are made overseas, in the headquarters of the multinational firms that dominate most sectors of the economy. Instead, the paper suggests that an industry development approach currently being used in Australia, the Action Agenda approach, be modified to include a broader range of players, notably the public sector R&D community and an industry's 'users', to think about and establish R&D priorities which will underpin progress in the industry as a whole rather than being restricted to individual firms. The proposal rests on the results of AEGIS empirical research (surveys and interviews) into the dynamics of innovation in different 'product systems' (broader than sectors) in Australia which indicates the broad range of players that need to be included both in the analysis of innovation and in policies for stimulating the research which can assist innovation.     

‘I feel something is still missing’: leisure meanings of African refugee women in Canada

This research explored the leisure meanings of three African women, former refugees resettled in Canada. Using a hermeneutic phenomenological approach, this study revealed that leisure meanings were tightly bound in the women’s Christian faith, church, and faith community in affording them solace, socialisation, and community bonding. Furthermore, learning for leisure emphasised leisure for educational advancement, self-improvement, and knowledge-gain, to keep busy, and for companionship. Physically active leisures afforded fitness and fun, while nature-based leisure, particularly with friends, family, and their ethnocultural communities were important for restoration, nurturing relationships, and fostering social networks. These leisures also served to mitigate traumatic memories and stress. Because of the prominence of their Christian faith and the church as central to these women’s leisure, collaborative efforts by faith-based entities, leisure and recreation organisations and practitioners, settlement agencies, and mental health bodies, are recommended to effectively address the challenges and aspirations of resettled African women refugees through leisure.     

The challenge for women expatriates and spouses: some empirical evidence

This is an exploratory study examining issues associated with women expatriates and their spouses. Individuals representing three groups - organizations, women expatriates, male spouses - were interviewed to identify their experiences and concerns. The authors conclude that this issue will pose a dramatic challenge for international organizations in the coming decades, and that it is timely to investigate the issue in more depth.     

Employee involvement and participation: developing the concept of institutional embeddedness using WERS2004

It is widely accepted that employee involvement and participation (EIP) is a key component of the high commitment bundle of HRM, but that it can take a range of forms in practice. Much of the analysis to date has either treated different forms of EIP as a single construct or has measured EIP by virtue of its presence or absence alone. Drawing on earlier work based on the data from WERS1998 examining the link between various forms of EIP and employee outcomes such as job satisfaction and organisational commitment, the authors re-apply and extend these ideas to data from WERS2004. In particular they develop the concept of institutional embeddedness, in order argue that both the depth and breadth of EIP have important associations with commitment though not with satisfaction.

This association held for workplaces employing 25 or more workers, and here it was apparent that the more that employees are involved at workplace level – through a wider number of EIP practices that are held more frequently and include opportunities for workers to have their say – the more likely it is that investments in EIP will reap the reward of organisational commitment. For smaller establishments, given that they tend to operate with relatively few formal schemes, it is likely that managers in these workplaces find alternative ways in which to engage the workforce, and that informal EIP offer similar levels of embeddedness in these situations. A clear implication to be drawn from the findings is that, in a context of lower levels of formality within organisations (large and small), line managers are more than ever the key link between HR policy and the embodiment of actual practice at the workplace.
