Position limits for cash‐settled derivative contracts

Cash settlement of derivative contracts makes them susceptible to manipulation by traders who expect to close large positions upon final settlement. Cash settlement also increases underlying volatility when hedgers unwind their hedges if they have no incentives to control their trading costs. Limits on the positions that traders can carry into final settlement can be used to mitigate associated economic inefficiencies when surveillance is insufficient. This article develops a model that regulators can use to set these limits that is based upon microstructure theory. The empirical findings indicate that existing position limits are largely inconsistent with those suggested by the model. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:945–965, 2005     

Corporate Cultural Change – Is It Relevant For the Organisations of the 1990s?

Partly as a consequence of the popularity of the ‘excellence’ literature of the early 1980s, there was a widespread acceptance that ‘corporate cultural change’ was one of the effective mechanisms within a strategic HRM approach to people management. However, recent research into imposed cultural change programmes in the late 1980s raises doubts about their effectiveness as change mechanisms, as management control devices and as contributors to business performance. This article engages in the current debate concerning the aims, design and implementation of cultural change but goes on to question the relevance of such an idea for organisations in the context of the 1990s. the article extends the many debates within the HRM and corporate culture literature by contextualising them within the emerging features of organisations in the 1990s.     

The structural and economic implications of urbanization

"This study surveys the policy issues associated with urbanization following the abolition of the pass laws [in South Africa]. The demographic background is briefly sketched. Using neo-classical analysis as a starting point, particular attention is paid to the present inefficiencies of city form associated with segregation. It is argued that current planning procedures are in danger of perpetuating or even worsening the situation. Obstacles to employment generation are considered and transport, local government and housing issues are discussed. On every front, urbanization policy is unstable and, even in the short term, there will be pressures to change it."     

Measurement of the Socioeconomic Impact of Lake Restoration: An Assessment Model Employing a Benefit/Cost Cross-Impact Probabilistic Approach

A bstract . A number of lake restoration demonstraton projects have been launched by the Environmental Protection Agency as a result of Public Law 92-500. To evaluate the cost-effectiveness of these public investment projects requires the development of an assessment model. The proposed Benefit/Cost Cross-Impact Probabilistic Approach (BCCIPA) is one attempt at assessing the interdependent socioeconomic and environmental impacts of the lake restoration project over time, both quantitatively and qualitatively, so that various changes brought about by the project can be investigated and evaluated in two comparative stages for three points in time—before, during and after project implementation.     

Health and development∗

The linkage between development and health is clearly spelt out in the definition of primary health care by the World Health Organisation. There is a widespread and growing disillusionment with the traditional Western approach to health care which fails to meet the real demands of the Third World situation.

This paper looks briefly at conditions in the developing world and the strategy proposed by the W H O to attempt to meet the objective of health for all by the year 2000 and refers to the South African situation.     

Income distribution,economic structure and employment in South Africa

This paper discusses the impact of a redistribution of current income from the White to the Black population on the distribution of sectoral output, and total employment by means of a semi‐closed input‐output model.

The results show that a redistribution of current income towards Black households — which no doubt will have positive social and political repercussions — has a non‐negative effect on GDP and a definite positive effect on the performance of sectors with a high private consumption expenditure component, as well as on total employment.     

Social distance and shopping behavior

This research was designed to see whether a reconceptualization of social distance (as measured by social class variables) between shoppers and stores would provide a basis for understanding store avoidance behavior. A survey of shoppers classified into two distinct social classes investigated their images, including social class images, of two stores that had been selected as representatives of upscale and downscale retailers. A new measure of social distance was proposed and evaluated. Controlling for other functional aspects of store image such as price and personnel, the social distance measure was found to be influential in discriminating shopping frequency groups for the two stores, providing evidence that people tend to avoid stores that are perceived as being socially distant from themselves.     

When consumers complain: A path analysis of the key antecedents of consumer complaint response estimates

When do consumers complain? This study probes this question by developing a conceptual framework that includes multiple theoretical perspectives, empirically testing a portion of the proposed model, and using dissatisfaction/complaint data from three different service industries. The hypothesized model uses multidimensional consumer complaint response estimates including voice, private, and third-party responses as dependent variables. Results support several proposed relationships, provide a high level of explained variance, and indicate a moderating role for dissatisfaction intensity. The complaint response estimates are characterized by disparate influence pathways, and expectancy value judgments emerge as critical determinants with positive and negative crossover effects. Attitude toward complaining is more dominant under low dissatisfaction intensity than it is under the high dissatisfaction condition. Important differences emerge across service categories. Implications of this work for managers and researchers in understanding when consumers complain are enumerated.     

General retail patronage loyalty as a determinant of consumer outshopping behavior

Consumer outshopping research has shown there are significant, but weak, relationships between consumers' attitudes toward local retailers and the degree to which they shop in local versus outlying areas. An alternative attitude measurement, retail patronage loyalty, is proposed and empirically evaluated. The loyalty scale was shown to be a stronger and more generalizable predictor of consumer outshopping behavior.
