In this study, productivity growth in 35 Australian universities is investigated using non-parametric frontier techniques over the period 1998–2003. The five inputs included in the analysis are full-time equivalent academic and non-academic staff, non-labour expenditure and undergraduate and postgraduate student load while the six outputs are undergraduate, postgraduate and Ph.D. completions, national competitive and industry grants and publications. Using Malmquist indices, productivity growth is decomposed into technical efficiency and technological change. The results indicate that annual productivity growth averaged 3.3% across all universities, with a range from -1.8% to 13.0%, and was largely attributable to technological progress. However, separate analyses of research-only and teaching-only productivity indicate that most of this gain was attributable to improvements in research-only productivity associated with pure technical and some scale efficiency improvements. While teaching-only productivity also contributed, the largest source of gain in that instance was technological progress offset by a slight fall in technical efficiency.

Efficiency, technology and productivity change in Australian universities, 1998-2003

This paper uses household level data to model residential water demand in Brisbane, Australia from 1998 to 2004. In this system, residential consumption is charged using a fixed annual service fee with no free entitlement and a fixed volumetric charge per kilolitre. Water demand is specified as quarterly household water consumption and demand characteristics include the contemporaneous and lagged marginal price of water, household income and size, and the number of rainy (with at least some precipitation) and warm (greater than 19.5°C) days. The findings not only confirm residential water as price and income inelastic, but also that the price and income elasticity of demand in owner-occupied households is higher than in renter households. However, the results also show that weather, especially the number of warm days, is likely to exert a much greater influence on residential water consumption than any factors subject to the usual demand management strategies.

Modelling residential water demand with fixed volumetric charging in a large urban municipality: The case of Brisbane, Australia

This article examines market risk in four demutualized and self-listed stock exchanges: the Australian Stock Exchange, the Deutsche Borse, the London Stock Exchange and the Singapore Stock Exchange. Daily company and the Morgan Stanley Capital International (MSCI) Index returns provide the respective asset and market portfolio data. A bivariate GARCH model is used to estimate time-varying betas for each exchange from listing until 7 June 2005. While the results indicate significant beta volatility, unit root tests show the betas to be mean-reverting. These findings are used to suggest that despite concerns that demutualized and self-listed exchanges entail new market risks that merit regulatory intervention, the betas of the exchange companies have not changed significantly since listing. However, market risk does vary considerable across the exchanges, with mean time-varying betas of 0.56 for the Deutsche Borse, 0.66 for the London Stock Exchange, 0.78 for the Singapore Stock Exchange, and 0.95 ...

Market Risk in Demutualized Self-Listed Stock Exchanges: An International Analysis of Selected Time-Varying Betas

Purpose – Farmers' exposure to pesticides is high in developing countries. As a result many farmers suffer from ill‐health, both short and long term. Deaths are not uncommon. Seeks to address this issue.Design/methodology/approach – Field survey data from Sri Lanka are used to estimate farmers' expenditure on defensive behaviour (DE) and to determine factors that influence DE. The avertive behaviour approach is used to estimate the costs. Tobit regression analysis is used to determine factors that influence DE.Findings – Field survey data show that farmers' expenditures on DE are low. This is inversely related to high incidence of ill health among farmers using pesticides.Originality/value – The results of this study are useful, not only for Sri Lanka, but also for many countries in South Asia, Africa and Latin America in reducing the current high levels of direct exposure to pesticides among farmers and farm workers using hand sprayers. Farmers' exposure to pesticides is a major occupational health hazar...

Exposure to pesticides, ill‐health and averting behaviour: costs and determining the relationships

In this paper, we study the synthesis of Gegenbauer processes using the wavelet packets transform. In order to simulate a 1-factor Gegenbauer process, we introduce an original algorithm, inspired by the one proposed by Coifman and Wickerhauser [1], to adaptively search for the best-ortho-basis in the wavelet packet library where the covariance matrix of the transformed process is nearly diagonal. Our method clearly outperforms the one recently proposed by [2], is very fast, does not depend on the wavelet choice, and is not very sensitive to the length of the time series. From these first results we propose an algorithm to build bases to simulate k-factor Gegenbauer processes. Given its practical simplicity, we feel the general practitioner will be attracted to our simulator. Finally we evaluate the approximation due to the fact that we consider the wavelet packet coefficients as uncorrelated. An empirical study is carried out which supports our results.
