Quality of life (QoL) is now widely recognised as a multidimensional concept. This study validates an instrument to measure multidimensional QoL, and investigates the relationships between the domains thereof. The domains analysed are: health, housing and infrastructure, socio-economic status, social relationships, governance and safety. We utilise a rich household-level dataset collected by the GCRO on QoL in the Gauteng city-region of South Africa.

In this paper, we estimate income elasticities and investigate the determinants of alcohol and tobacco consumption in Lesotho using a Double-Hurdle model on the 2002/03 Lesotho HBS data. The results reveal that both alcohol and tobacco are income inelastic with estimated elasticities of 0.6553 and 0.3561, respectively. Given this, therefore, we argue that differentiated tax hikes, with a relatively higher rate on tobacco, can be more effective both as a consumption deterrent and revenue increasing policy, without much compromise on employment and poverty.
This paper presents research on South African household expenditure share behaviour. The research examines whether or not a theoretical and empirical model, which has been successful in explaining expenditure shares in Australia, is valid when applied to South African data. The primary conclusion of the research is that expenditure shares in South Africa do not conform to the assumptions set out in the model.
