Forecasting the volatility of S&P depositary receipts using GARCH-type models under intraday range-based and return-based proxy measures

We employ four various GARCH-type models, incorporating the skewed generalized t (SGT) errors into those returns innovations exhibiting fat-tails, leptokurtosis and skewness to forecast both volatility and value-at-risk (VaR) for Standard & Poor's Depositary Receipts (SPDRs) from 2002 to 2008. Empirical results indicate that the asymmetric EGARCH model is the most preferable according to purely statistical loss functions. However, the mean mixed error criterion suggests that the EGARCH model facilitates option buyers for improving their trading position performance, while option sellers tend to favor the IGARCH/EGARCH model at shorter/longer trading horizon. For VaR calculations, although these GARCH-type models are likely to over-predict SPDRs' volatility, they are, nevertheless, capable of providing adequate VaR forecasts. Thus, a GARCH genre of model with SGT errors remains a useful technique for measuring and managing potential losses on SPDRs under a turbulent market scenario.     

The drama of interaction within business networks

We propose a dramaturgical approach to the understanding of business networks with particular reference to IMP research. Our purpose is to focus upon immeasurable processes and practices too often neglected by the tangible, variance modeling of business networks (Colville & Pye, 2010; Rinallo & Golfetto, 2006). This paper follows our call to take language and communication more seriously (Ellis, Lowe & Purchase, 2006). The inventive fluidity of communication, in the form of dramaturgy, when added to the rather more entitative IMP model of Actors, Resources and Activities (Håkansson & Snehota, 1995) creates a more processual, theatrical ‘scenario’ of Actor-Characters, Resource Props and Scripted Activities. We employ the dramaturgical approach of Goffman (1956, 1961) which, in keeping with the approach of the IMP Group is centrally attentive to social interaction. In order to illustrate the potential contribution of this approach, we apply this dramaturgical perspective to the interactions described in a published case study (Helander & Möller, 2007, 2008a, 2008b).     

Implementing STD on a Small Island: Development and Use of Sustainable Tourism Development Indicators in Samoa

Small island states present a significant challenge in terms of sustainable tourism development. On a small island there are limited resources, economic and social activities tend to be concentrated on the coastal zone, and the interconnectivity between economic, environmental, social, cultural and political spheres is strong and pervasive. Consequently the sustainable development of tourism is more a practical necessity than an optional extra. This paper investigates the question of how to monitor sustainable tourism development (STD) in Samoa, an independent small island state in the South Pacific. It describes some of the methodological considerations and processes involved in the development of STD indicators and particularly highlights the importance of formulating clear objectives before trying to identify indicators, the value of establishing a multi-disciplinary advisory panel, and the necessity of designing an effective and flexible implementation framework for converting indicator results into management action.     

GPs as firms: Creating an internal market for primary care

Outsiders are often amazed at the lack of contact and communication between general practitioners and other members of the primary care team on the one hand, and the rest of the national health service on the other. One way to help close the gap and improve services generally would be to provide GPS with appropriate incentives.     

Globalization,employment relations and human resources indicators in ten developed market economies: international data sets

This paper provides statistical information on internationalization, human resources and labour market outcomes in ten important developed market economies (DMEs). Such data are useful for practitioners and academics who are interested in international HRM. The article's aim is to provide easily accessible statistical tables of selected characteristics, which can be used to draw initial comparisons between countries and to test competing accounts of the impact of globalization on national patterns of employment relations. It includes standard sources so readers can elaborate and update these data.     

Public spending and old age

With the elderly, as with other beneficiaries of the welfare state, need seems to rise faster than available resources. A closer look at the precise nature of the need can lead to a better balance between cash payments and service provisions. And, in the end, quite modest proposals can lead to significant benefits.     

Corporate strategy financialized: Conjuncture,arbitrage and earnings capacity in the S&P500

The conjuncture that ushered in the era of shareholder value served to embed capital market expectations into corporate governance aligning management and shareholder interests. Market arbitrage focussed on modifying contractual relations with stakeholders to extract a (higher) return on invested capital. In this article we focus on cash earnings on capital employed generated by the S&P 500 survivor group of firms covering the period 1990–2008. We use this financial data to construct three complementary perspectives on corporate financial performance: firm, firm-relative and macro. Within this framework the financial numbers and perspectives are analogous to a ‘hall of mirrors’ where ambiguity and contradiction are in play frustrating straightforward performative narratives that connect purpose with financial transformation an era of shareholder value.     

From welfare state to entitlement programmes

This paper reviews the record on the development of the welfare state. The Beveridge model though world famous had few imitators and insurance based models were more common. The irony of development was that the United States which had the greatest resistance now has the most severe problem with rising spending. From 1990 onwards there was a phase of reform with three there key variables in play, concern about competitiveness (Germany), the power of recipients of entitlement programmes (US) and concerns about work incentives (UK). The recession has made the problem of containing welfare spending more urgent but the political resistance has increased. The welfare state, the consensus programme for social solidarity of the twentieth century was set to be he focus for political conflict and social division in the 21st century.     

The forgotten employees? The experiences of expatriate staff returning to the UK

This article reports on the experiences of a group of expatriate UK managers and professionals who have recently returned to the UK from foreign assignments. A brief review of the literature in this field is presented and the findings of a questionnaire survey of 124 ‘returnees’. The data show that many expatriates face difficulties upon their return in terms of their career prospects, psychological well-being and general adaptation to life back home. The paper goes on to suggest ways in which these transitions can be managed more effectively by organizations and individual employees. It concludes by proposing directions for future research.     

Independent tourist's automobilities in Norway

This paper critically examines the methods of transportation used by independent tourists and how importantly they value mobility throughout their journeys. While independent tourists are frequently identified as being adventurous and highly mobile, relatively few researchers have critically examined the modes of transport they use or the importance they play in enhancing and fulfilling their desired experiences. Indeed, most literature portrays independent tourists as habitual users of public transport as opposed to modes of personal transport. In this paper, the notion of automobility – a combination of autonomous and self-directed movement – is explored from the perspective of independent tourists in Norway. A multi-method qualitative study was undertaken which analysed the views of 38 independent tourists at eight different locations. The findings revealed that personal modes of transport were intrinsic features of the journeys undertaken and that they offered alternative sensory experiences in contrast to public transport. Moreover, for many independent tourists, autonomous journeys were considerably more important than the destinations they visited. Thus, for many independent tourists in Norway, demands for control, flexibility and adventure could only be satisfied by using particular modes of transport.
