Planning and control from the perspective of labour: A short presentation of the demos project

The objective of the DEMOS project (Democratic Planning and Control in Working Life) is the development of knowledge about planning, control and computer use. It is based upon the interests of workers and their trade unions and consists of two parts. The first is the study and analysis of corporate planning, control and computer use in cooperation with investigative groups in selected local unions, simultaneously testing trade union procedures in investigations. The second part relates to the development of alternative theories and research methods which differ from the current, dominating perspective. The project is expected to be of significance to continued interdisciplinary research on working life with a trade union connection. The results can be of use in trade union negotiations and judgements, both centrally and locally, and constitute a basis for educational materials both for unions and for state schools.     

A dynamic model of housing production

This paper derives the optimal development strategy for a housing producer with perfect foresight in a steady-state environment where dwellings deteriorate as they age. Under the assumption of zero demolition costs, the optimal strategy is an infinite sequence of identical buildings. Building abandonment is shown to be possible with positive demolition costs. A solution highlighting the model's spatial properties is computed using Cobb-Douglas functions.     

Consistent estimation of correlations between observed interval variables with skewed distributions

Departures from multinormality due to skewness in observed distributions may result in inconsistent estimates of product-moment correlations between interval variables. Therefore, the robustness of the product-moment correlation estimator against skewness in the distributions of sample data on interval variables has been investigated. This estimator is robust against skewness of maximally about 1 in absolute value. If the observed distributions have larger skewnesses, the sample data on interval variables may be redistributed over normally distributed discrete variables with 10 categories each. The estimated polychoric correlations between these discrete variables represent consistent estimates of the product-moment correlations between the original interval variables in the population.     

Forecasting Housing Approvals in Australia: Do Forecasters Herd?

Price trends in housing markets may reflect herding of market participants. A natural question is whether such herding, to the extent that it occurred, reflects herding in forecasts of professional forecasters. Using more than 6,000 forecasts of housing approvals for Australia, we did not find evidence of forecaster herding. On the contrary, forecasters anti‐herd and, thereby, tend to intentionally scatter their forecasts around the consensus forecast. The extent of anti‐herding seems to vary over time. We also found that more pronounced anti‐herding leads to less accurate forecasts.     

Enhancing market power by reducing switching costs

A proportional decrease in switching costs increases competition and social welfare. However, a lump-sum decrease in switching costs softens competition and does not invariably increase social welfare.     

Frontiers, Intersections and Engagements of Ethics and HRM

This essay, and the special issue it introduces, sets out to reignite ethical interrogations of the theory and practice of Human Resource Management (HRM). To cultivate greater levels of boundary-spanning debate about the ethics of HRM, we develop a framework of four tenors for scholarly work: the ethical-declarative, the ethical-subjunctive, the ethical-ethnographic, the ethical-systemic. Each of these tenors denotes particular grounds for ethical critique and encourages scholars to consider the subjects and objects of their enquiry, the disciplinary scope of their work and the limits to subsequent claims about ethics and HRM. We provisionally locate each of the papers comprising the special issue with regard to one, or more, of these tenors.
