Efficiency in South African water utilities: a comparison of estimates from DEA, SFA and StoNED

Climate change has brought renewed and increasing attention to the productivity and efficiency of the water sector. This has stimulated interest, which has manifested itself in the increased application of statistical tools to measure the productivity and efficiency of water utilities. Policymakers in developed countries are already making use of statistical analyses of water systems for determining productivity and efficiency.

Financial Sustainability of Tanzanian Saving and Credit Cooperatives

This paper examined the profitability and financial sustainability of Saving and Credit Cooperatives (SACCOs) in Tanzania. The data set used in this study came from SACCOs’ audited financial reports for the year 2011. Profitability was estimated using return on assets and financial sustainability was estimated using the ratio of total expenses to total revenue. Linear regression was used to investigate the determinants of financial sustainability.

Does training benefit those who do not get any? Elasticities of complementarity and factor price in South Africa

Commentators claim a shortage of skills, particularly artisanal labour, in South Africa is constraining output and that a rise in skill supply would benefit less skilled occupations. This assumes/implies skilled and unskilled labour are q-complements. This paper estimates Hicks Elasticities of Complementarity and elasticities of factor price. Aggregate estimates suggest more skilled (white collar) labour complements less skilled (blue collar) labour, so a rise in skill supply would lead to a rise in demand for less skilled labour.

DEA Applied to a Gauteng Sample of South African Public Hospitals

The ability of the South African government to provide antiretroviral medication to those in need will be determined by the ability of the public health services sector to efficiently provide that medication. If the delivery of other health services can be used as a guide, the goals of the anti-retroviral rollout will not be met. The research presented in this paper provides a preliminary analysis of the delivery of a few health care services by the public sector in Gauteng, South Africa.
