Optimal stockpiling in a high-risk commodity market the case of copper

Economists recognise the need for making decisions which are sensitive to risk, but they have been unable to compute the decisions which satisfy the von Neumann-Morgenstern theory of choice under risk in a multivariable dynamic context. This paper explores sequential decision rules which optimise a second-order approximation to von Neumann-Morgenstern utilities, with arbitrary probability distributions and intertemporal stochastic dependence. These rules are used to generate optimal stockpiling rules for stabilising the price in a high-risk commodity market. A clear trade-off emerges between the ambition and security objectives of market management.     

Some 'real' problems of 'virtual' organisation

This paper presents an ethnographic study of organisational change in a retail bank considering issues surrounding the supposed emergence of the 'virtual organisation'. It outlines emerging problems in organisational work as a consequence of the shift toward 'virtuality' and questions the explanatory value of such theoretical stances.     

‘Devolution’ of transport powers to Local Government: Impacts of the 2004 Traffic Management Act in England

The concept of ‘Devolution’—the transfer of powers away from the Central Government to more local bodies of Government, has been used across many different areas of policy and by many different national governments. This paper examines the devolution of transport powers to the existing Local Traffic Authorities in England via the 2004 Traffic Management Act. The paper first presents a summary of how several different nations have undertaken this process of devolving transport powers and responsibilities to either new or existing bodies. It then presents research from an electronic survey concerning how English Local Traffic Aut`horities are choosing to use some of the new powers available to them and their opinion on complementary areas of transport policy. Research is also presented from structured telephone interviews, concerning how individual Local Authorities perceive the efficacy and equity of the new legislation. Overall, the results show that only some of these new powers are likely to be used by English Local Authorities, with limited variation in how different types of LTA are choosing to implement these new powers. The structured telephone interviews provided some evidence that rural Authorities in particular are more dissatisfied with the legislation and consider some of the measures unhelpful. The results provide some insights on the formulation of devolved policy applicable to existing Local Government bodies and the varying benefits that can be perceived to apply to different types of Local Authority. Conclusions are drawn on some of the practical difficulties arising from the English experience, and lessons of relevance are drawn for other nations considering a similar devolution of transport powers.     

Why sales reps should welcome information technology: Measuring the impact of CRM-based IT on sales effectiveness

This study seeks to answer the following question: Can sales representatives enhance their performance through their acceptance of information technology (IT) tools? Using data collected from two companies, we show that despite uncertain results and the frequent resistance among salespeople to IT interventions, IT acceptance indeed has a positive effect on sales performance. This occurs because salespeople using IT expand their knowledge and, in turn, gain improved targeting abilities, enhanced presentation skills, and increased call productivity. Thus, sales representatives have a strong incentive to accept IT because doing so is likely to sharpen their own job performance.     

Linking Ethics and Risk Management in Taxation: Evidence from an Exploratory Study in Ireland and the UK

Ethical dilemmas involving tax issues were identified by members of the American Institute of Certified Public Accountants as posing the most difficult ethical problem for them (Finn et al., Journal of Business Ethics 7(8), pp. 607–609, 1988). The KPMG tax shelter fraud case proves that the tax profession has not gone untainted in the age of numerous accounting and corporate scandals, such as the Enron débacle (Sikka and Hampton, Accounting Forum 29(3), 325–343, 2005). High-profile scandals serve to highlight the problems caused by differences in ethical judgement among accountants and tax practitioners and the issue of ethics has been brought publicly to the forefront of the profession. Nevertheless, the nature and dimension of ethical issues in tax practice have been largely unexplored (Erard, Journal of Public Economics 52(2), 163–197, 1993; Marshall et al., Journal of Business Ethics 17(12), 1265–1279, 1998; Frecknall Hughes, Unpublished PhD Thesis, The University of Leeds, 2002). This research aims to contribute to the debate on ethics in tax practice by reporting interview data on tax practitioners’ perceptions of ethics in the jurisdictions of Ireland and the United Kingdom and exploring the link or equation of ethics with risk management.     

Government support for tourism and the UK: A different perspective

The nature of government support for industry in the UK is examined. Support for tourism has not equalled that given to manufacturing but the grounds on which the case for tourism are argued are unsatisfactory. The circumstances where a free enterprise economy could be reconciled with increased government support for tourism are argued. A case is made for subsidized holidays and it is suggested that cash grants for tourism development are inappropriate and should be replaced by other forms of funding.     

A New Method for Estimating the Effects of Fuel Taxes: An Application to Thailand

This article proposes a new methodology for estimating the impactof fuel price and tax changes on the general price level andthe distribution of income and applies a model to Thailand usingdata for 1975–76 and 1981–82. Because the modelallows for pricing under international competition where taxincreases must be partially absorbed in reduced factor incomerather than always being passed on in higher consumer prices,the results are significantly different from those generatedby the more conventional cost-plus pricing rule. The inflationaryimpact of fuel tax changes is slight because of both the opennessof the economy and the low energy intensity of manufacturingand other production in Thailand. In contrast, taxes on importsengender price increases not only for imports but also for goodswhich substitute for imports. The model also indicates thatthe net effects of taxes on petroleum products (other than kerosene)are progressive in their distributional impact, relative toa tax on imports or consumption. A main policy conclusion ofthe study is that fuel taxes could be used to increase bothequity and allocative efficiency without inducing significantinflationary responses. It follows that in the current circumstancesof falling world oil prices, developing countries could generaterevenues needed for structural adjustment by increasing fueltaxes to maintain domestic petroleum price levels.
