Computer technology and the job of the First-Line Supervisor

This article presents a detailed case study of changes in the job tasks of British Rail yard supervisors under the routine operation of a computerised system of freight information control in order to critically evaluate the claim that computer technology is contributing to the demise of first-line supervisors.     

An application and extension of a multidimensional ethics scale to selected marketing practices and marketing groups

The purpose of this research was to test and extend a multidimensional ethics scale developed by Reidenbach and Robin to selected marketing groups. Different marketing practices and groups were used in order to give these measures a wide variety of exposures. These measures performed well in all settings and for all practices. Factor structures in fifteen different trials identified the same three dimensions with one exception. In that exception, two dimensions merged together in five of those fifteen trials. While these dimensions captured much of the variance in the global concept of “ethical/unethical”, they did a better job of predicting the respondents’ intention to behave than the global measure. These measures also provide the researcher with a partial explanation of why the respondents answered in the manner that they did. The shifting relative importance of the three dimensions in accounting for the variance in the behavioral intention measure provides this explanation.     

The impact of volatility derivatives on S&P500 volatility

This study investigates whether the newly cultivated platform of volatility derivatives has altered the volatility of the underlying S&P500 index. The findings suggest that the onset of the volatility derivatives trading has lowered the volatility of both the cash market volatility and the cash market index, and significantly reduced the impact of shocks to volatility. When big sudden events hit financial markets, however, the volatility of volatility seems to elevate in the U.S. equity market as a result of increased global correlations. Regardless of the period under examination and the estimator employed, long‐run volatility persistence is present. The latter drops significantly when the credit crunch period is excluded from the post‐event date sample period. The correlation between the broad equity index and the return volatility remains low, which in turn strengthens the role of volatility derivatives to facilitate portfolio diversification. The analysis also shows that volatility is mean reverting, whereas market data support the impact of information asymmetries on conditional volatility. In the post‐event date phase, no asymmetries are found when the recent crisis is not accounted for. Finally, comparisons with other international equity indices, with no volatility derivatives listed, unveil that these indices exhibit higher volatility and slower recovery from shocks than the S&P500 index. © 2009 Wiley Periodicals, Inc.

THE ECONOMIC SCIENCE FICTION OF CLIMATE CHANGE: A FREE‐MARKET PERSPECTIVE ON THE STERN REVIEW AND THE IPCC

The Stern Review and the IPCC believe that anthropogenic climate change is a serious global threat and demands an urgent response. Examining the IPCC's projections of future climate change and Stern's estimates of its costs from a free‐market perspective shows that they are based on flawed methodological assumptions and reflect an excessively optimistic approach to knowledge of the future. The foundations of reliable knowledge for a sound policy framework have not been put in place.     

The Economic Analysis of Industrial Accidents: a re-assessment

Conventional economic approaches to the analysis of industrial accidents utilise the hedonic pricing approach. This approach usually excludes potentially important institutional, sociological and macroeconomic determinants of occupational safety. Initially we identify some of the theoretical and empirical problems with orthodox economic analysis in this area. An alternative model is then formulated which explicitly encompasses a broader range of determinants. Finally, the model is tested using UK industry accident data, the results being inconsistent with the compensating differentials' emphasis of orthodox analysis but supportive of the augmented model.     

Economics Courses Offered and Required in Two-year Colleges

Reporting the results of a nation-wide survey of economics in junior colleges, Dawson lists the courses given and indicates which students are required to take economics. Not surprisingly, Principles of Economics is most common, and business students are the ones most likely to be required to take it. The average number of courses offered is three, although some schools offer as many as 10. A breakdown by type of college (public, independent, church-related) is presented, and suggestions for improvement are offered.     

Using identity structure analysis (ISA) to investigate female entrepreneurship

The process of founding a business is for most people a period of transition entailing taking on a new role. Such a transition will often result in a change of values and beliefs. For some women, values ascribed to the entrepreneur will conflict with conventional feminine values. Previous researchers have classified women in accordance with their degree of attachment to entrepreneurial values and conventionally defined masculine-feminine values (Goffee and Scase 1985, Cromie and Hayes 1987), but to date there has been little attempt to examine the process of change in women's values and beliefs as a result of business start-up.

This paper reports on the first attempt to use Identity Structure Analysis (Weinreich 1980/1986/1988) to investigate entrepreneurship: in this case, specifically female entrepreneurship.     

Purposive Leisure: Examining Parental Discourses on Family Activities

Current social psychological definitions of leisure may not adequately capture or describe family leisure. This study used discourse analysis to explore the meanings of family leisure as revealed by parents of preteen children (aged 10-12 years). The data came from a study of 31 families (23 two-parent families and 8 one-parent families) living in Ontario, Canada. Thirty mothers and 23 fathers were interviewed about their family leisure activities, experiences, attitudes, and beliefs about family participation. Analysis showed that family participation was highly valued by all of the parents. However, rather than being freely chosen or intrinsically motivated, family leisure was purposive in that it was organized and facilitated by parents in order to achieve particular short- and long-term goals. One set of goals related to family functioning, including enhanced family communication and cohesion, and a strong sense of family. Another set of goals related to the beneficial outcomes of family activities for children, including learning about healthy lifestyles as well as learning moral values. It is argued that the purposive nature of this form of leisure practice reflects current ideologies about motherhood, fatherhood, and the family in North American society.     

Political Processes in Management,Organization and the Social Shaping of Technology

The notion of path dependence is regularly deployed to account for the way past commitments have an important bearing on current choices. We make a distinction between the notions of past and path dependence and focus on path dependence as two types of event sequences: selfreinforcing and reactive. We then address the issue of how the notion of path dependence can be reconciled with a temporal-relational perspective on agency. These notions are tested and refined using a longitudinal case study of ICI's move away from chlorofluorocarbons (CFCs) and the decision to build three plants to produce one CFC alternative (HFC-134a) for the global refrigeration market. The paper concludes with a discussion of the implications of path dependence for research on technological and firm evolution.     

Austrian economics and climate change

The aim of this paper is to outline and defend an Austrian policy response to climate change. A privatised climate change policy, based on Austrian welfare economics, is the only way to defend to the greatest possible degree the liberties both of fossil fuel users and people whose property rights will be violated if carbon emissions cause climate change. Neoclassical and ‘Post-Austrian’ analyses of climate change are both theoretically unsound and impractical, in requiring for their implementation a foundation in reliable scientific knowledge that is not available. Anthropogenic climate change is a putative interpersonal conflict rather than market failure. The use of fossil fuels should be subject to side-constraints designed to avoid the infringement of other people’s property rights. Tort litigation would protect these rights, where necessary. Litigation would also promote the public understanding and even the advancement of climate science.
