INTERNATIONAL DIVERSIFICATION OF EQUITIES AND FIXED-INCOME SECURITIES

Portfolio selection models have been applied principally to common stocks traded in the United States and in foreign stock markets. This study examines the efficient set of portfolios selected from a choice set that includes returns derived from domestic and international corporate bond and government bond indices as well as domestic and international stock indices. To assess the benefits of international multi-asset diversification, the authors examine the following issues: (1) the extent to which international and domestic fixed-income securities are included in efficient portfolios; (2) the effect on efficient set composition of using the Sharpe portfolio selection model as compared to the Markowitz portfolio selection model; (3) the sensitivity of efficient set characteristics produced from a single-index based portfolio selection model to alternative world market indices; and (4) the correspondence between expected and realized portfolio risk and return for the different portfolio selection models.     

Sustainable procurement practice

Procurement has a key role in sustainability as policies and practices need to extend beyond organisations' boundaries incorporating their whole supply chains. Guidelines on sustainability encourage procurement to make decisions that encompass the environmental, economic and social elements of the Triple Bottom Line (TBL). Taking a supply chain perspective, procurement also need to analyse how decisions impact on the TBL in respect of suppliers. The results of a survey of sustainable procurement practices in 44 English‐based UK Housing Associations (HAs), who are responsible for the provision of social housing, confirms prior research of other sectors that suggests 1) a failure to overcome inertia in relation to sustainable procurement; and 2) in the few examples where practices have been established, only the environmental element of the TBL is considered. The organisations surveyed have sustainability‐related issues in their missions and external and internal pressures to embed sustainability, yet this has not translated into widespread establishment of sustainable procurement. Recommendations to neutralise inertia are: firstly, take the experiences from other areas, e.g. innovation management, which stress the importance of inter‐organisational relationships; secondly, develop a small number of sustainable development indicators for procurement and, to take advantage of the relatively more‐advanced environmental practices to show how these elements have socio‐economic impacts; and finally, rather than focus on just the pressures and drivers of sustainability (as suggested in strategic models of sustainability), emphasise the triggers that overcome inertia and lead to changes in behaviour amongst procurement staff i.e. the establishment of ethical pricing models.

Assessing the adoption of HRM by small and medium-sized manufacturing organizations

This paper reports on exploratory research which uses a comparative case-study approach with sixteen organizations to study the extent to which HRM has been adopted in traditional brownfield-site, small and medium-sized UK manufacturing organizations. The paper begins with a comparison of HRM practices across the sixteen organizations. It is argued that the most common HRM practices in these firms appeared to relate more to a traditional small firm approach than to any proactive attempt to adopt HRM. The analysis shows that very few of the organizations adopted a strategic approach towards HRM with an integrated set of policies related to corporate strategy being put forward. Instead, the dominant approach seemed to be one of reactive, opportunistic pragmatism, showing little development from the standard modern approach identified as most common in the early 1980s. On the other hand, three organizations are shown to approximate quite closely to the model of strategic HRM and contextual analysis is undertaken to attempt to differentiate these from the other organizations. A comparison is also made between the findings of this research and a telephone survey that was conducted to assess the use of HRM in Leicestershire. The results of this show that a certain degree of caution should be exercised when accepting reports of organizational practices which do not involve researchers actually entering the organizations. Finally, the paper concludes that in order to get a better understanding of the situation facing these and other organizations we need to broaden our scope and consider the impact of changing economic, social and political conditions on management worker relations.     

为什么政府要私有化?

基于所搜集的1998年到2000年的数据,本文从理论和实证角度考察了私有化的决定因素。理论模型清楚讨论了银行在决定私有化中的角色。我们发现改进的人力资本和银行经理层激励和/或弱化的银行流动性限制导致私有制。我们也分析了在何种情况下,倒闭将是一种更好的办法。并且实证证据和我们模型的预期相一致。     

The SEC's retail investor 2.0: Interactive data and the rise of calculative accountability

The Securities and Exchange Commission (SEC) in the United States mandated a new digital reporting system for US companies in late 2008. The new generation of information provision has been dubbed by Chairman Cox, ‘interactive data’ (SEC, 2006a). Despite the promise of its name, we find that in the development of the project retail investors are invoked as calculative actors rather than engaged in dialogue. Similarly, the potential for the underlying technology to be applied in ways to encourage new forms of accountability appears to be forfeited in the interests of enrolling company filers.We theorise the activities of the SEC and in particular its chairman at the time, Christopher Cox, over a three year period, both prior to and following the ‘credit crisis’. We argue that individuals and institutions play a central role in advancing the socio-technical project that is constituted by interactive data. We adopt insights from ANT (Callon, 1986, Latour, 1987, Latour, 2005b) and governmentality (Miller, 2008, Miller and Rose, 2008) to show how regulators and the proponents of the technology have acted as spokespersons for the interactive data technology and the retail investor. We examine the way in which calculative accountability has been privileged in the SEC's construction of the retail investor as concerned with atomised, quantitative data (Kamuf, 2007, Roberts, 2009, Tsoukas, 1997). We find that the possibilities for the democratising effects of digital information on the Internet has not been realised in the interactive data project and that it contains risks for the very investors the SEC claims to seek to protect.
