A purposive sample of South African specialist surgeons was used to nonparametrically estimate production relations for single ouptut and multiple output production processes. The analysis was further extended to incorporate parametric assumptions associated with stochastic frontier analysis to...

A purposive sample of South African doctors provided data for the analysis of revenues, costs and earnings associated with specialist surgical medicine. Empirical analysis of the data, based on both nonparametric and parametric regression, finds that practice revenues increase by, on average,...

This study develops an economic fertility model which explicitly incorporates both the costs of childrearing and contraception behaviour. In this setting, a couple capacity to procreate depends on their fecundity, as well as their contraception and sexual behaviours; and the ideal number of...

The heavy dependence and inefficient utilization of biomass resources have contributed to the depletion of forest resources in Ethiopia, while the use of traditional cooking technology, one source of inefficient biomass resource use, has been linked to indoor air pollution and poor health. In...

Through the implementation of a choice experiment valuation exercise, this study set out to identify the set of community plantation attributes that impact the welfare of potential community forestry program participants. We employed a combination of choice models to evaluate the preferences,...

The South African Competition Commission's merger decisions for FY2002 through FY2009 are analyzed to empirically identify the factors historically influencing prohibition, conditional approval and unconditional approval. The key explanatory variables are linked to provisions of the 1998...

Existing literature have rarely evaluated distributive effect of Joint Forest Management (JFM) augmented with improved market linkages for non-timber forest products nor have they accounted for heterogeneity in the welfare effects. We assess the distributional impact of a unique JFM in Ethiopia...

This paper examines regional differences in the effect of user fee removal in rural areas of Zambia on the use of health institutions for delivery. The analysis uses quarterly longitudinal data covering 2003q1-2008q4. When unobserved heterogeneity, spatial dependence and quantitative supply-side...

South Africa waived user fees for primary health care, first in 1994, and again, in 1996. Since the 1994 plan focused on young children and older adults, as well as pregnant and nursing mothers, the 1996 change, which waived fees for the remainder of the population, subject to means tests, can...
