The options market response to accounting earnings announcements

We examine the reaction of the equity options market to accounting earnings announcements over the period 1996–2008 using changes in implied volatility to measure the options market response to earnings news. We find that positive earnings surprises and positive profit announcements produce a larger uncertainty resolution than negative earnings surprises and loss announcements. We demonstrate an inverse relation between the change in implied volatility and earnings news in a three-day window immediately after an earnings announcement. We refer to the magnitude of this relation as the ‘options market earnings response coefficient’. This ‘options market earnings response coefficient’ is stronger for both bad news announcements and positive profit announcements. We do not find any significant relation between changes in implied volatility and earnings news in the pre- or post-announcement periods. We conclude that the options market efficiently absorbs earnings information.     

An Analysis of Storage Capacity Reallocation Impacts on the Irrigation Sector

Significant attention has been given to the improvement of environmental flows in recent years. An important factor to reduce the opportunity cost of flood creation needed for the environment is the access to storage capacity. Reallocating storage capacity from agriculture to environment, however, may have important impacts on irrigation water prices and the vitality of irrigation enterprises. In this paper, the long term impacts of storage capacity reallocation on the agricultural sector are analysed. It is shown that a reduction in storage capacity for irrigation water will reduce water prices for each level of dam content and shift the distribution of dam content to the left. As a result, the value of the irrigation sector is reduced. The impact on average water price is, however, indeterminate, implying that results from previous empirical studies may be valid only locally and that sensitivity analysis is important to show the robustness of empirical results.     

Poverty and Inequality Maps in Rural Vietnam: An Application of Small Area Estimation

The objective of the present paper is to estimate poverty and inequality for rural Vietnam at different levels of aggregation by combining the Vietnam Household Living Standard Survey from 2006 and the Rural Agriculture and Fishery Census from the same year. Using the small area estimation method, estimates at the regional, provincial and district level are produced, and both expenditure and income based measures are considered. It is found that all provinces across the country have experienced a noticeable reduction in rural poverty during the period 1999–2006. Some of the largest reductions in poverty are observed for provinces with poverty rates close to the national average. The poorest provinces are experiencing reductions in poverty, albeit at a more modest pace. Provinces and districts with a larger poverty reduction in the period 1999–2006 tended to have a lower level of inequality in 2006. Results based on expenditure poverty estimates are found to be very similar to those based on income poverty estimates.     

Mixed signals in HRM: the HRM role of hospital line managers1

Recently, Haggerty and Wright suggested that HR could be reconceptualised as signals sent to employees rather than practices. We examine this novel approach and consider how it fits in the practice. In hospitals, ward managers are intermediaries in relation to signals that are passed between upper managers and their staff. We discuss to what extent ward managers have the analytical and functional skills required to interpret and convey complex signals to the staff under their jurisdiction. We draw conclusions about the role of ward managers in the HR function of hospitals. There are theoretical and practical implications for the role of line managers more generally, beyond the hospital context.     

Human resource strategies,workplace reform and industrial restructuring in Australia and New Zealand

In recent years, Australia and New Zealand have pursued two different routes of labour market reform. New Zealand opted for a radical experiment in the deregulation of industrial relations and other areas. Australia pursued a co-operative and co-ordinated approach to reform within the centralized arbitral system. Both reform initiatives were designed to stimulate improvements in organizational performance and cost competitiveness. In this paper, we argue that there are three main types of strategies that management can use to reduce labour cost and improve performance: productivity-enhancement, costminimization and work-intensification strategies. We argue that the former is a long-term sustainable strategy whereas the latter two are negative short-term strategies that may have deleterious longer-term effects. This paper reports the results of a cross-national survey in New Zealand and Australia into the extent of adoption of these management strategies. The results are presented by industry, employment size, mode of operation and countries as a whole. The research findings indicate that New Zealand's decentralization has encouraged a higher degree of employer experimentation with both positive and negative workplace change strategies, especially in the private sector. Australia's more centralized system limited the use of cost-minimization strategies but not productivity-enhancing strategies in the public and not-for-profit sector. The research found evidence of work intensification in both countries.     

Fearful asymmetry: The consumption of accounting signs in the Algoma Steel pension bailout

This paper examines the role of accounting in society by looking at the consumption of accounting signs during the financial restructuring of a corporation. The paper builds upon insights from prior research on accounting as simulacrum and hyperreality. It examines how accounting numbers serve as reconfigurable signs that construct appropriate “crises”, motivate government intervention, and marshal stakeholders towards solutions. The incident at the heart of this study is the 2001 bailout of the Algoma Steel pension plan by the Ontario government. The incident demonstrates how accounting technologies are required both for the production of accounting signs and for their consumption. The paper asks how the production and consumption of accounting signs is different from that of other communication signs, what role consumers of accounting signs play in determining their meaning, and what difference this makes in how corporate pension plans are protected by government. It concludes that the structures and mechanisms surrounding the consumption of accounting signs enable different stakeholders to influence the production of meaning at the moment when accounting signs are consumed, changing the way that risk and wealth are redistributed, and shaping government intervention.     

Data Feature: Earnings Biases in the United Kingdom Regional Accounts: Some Economic Policy and Research Implications

Between the late 1970s and late 1980s, the UK Regional Accounts data suggest a much smaller rise in the South East earnings premium and consequently a much smaller increase in the regional dispersion of earnings than do the other sources of data. We discuss several possible explanations for this discrepancy and conclude it was probably due to problems at the Inland Revenue in allocating tax records across the regions. The historical unreliability of the Regional Accounts has implications for economic research on regional consumption and convergence and may have caused the poorest regions to miss out on EU Structural Funds.     

The economic analysis of social customs: the case of pre-marital sex

This paper uses a sample of 18,876 adults aged 16-59 from to estimate logit equations of the determinants of support for the custom of abstaining from pre-marital sex. Three sets of equations are estimated separately for males and females; one set for disapproval of pre-marital sex, one set for disapproval of one night stands and another set for a proxy for involvement in pre-marital sex. These results confirm some expected male-female differences and also show a polarisation amongst the population in their support for, and observance of, customs and practices related to abstaining from sex before marriage.
