The empirical analysis includes both parametric and nonparametric regression. Parametric estimates of revenues per new patient range between R689 to R818, while cost per new patient estimates range between R694 and R749; average surgeon income per new patient falls within a similar range. Furthermore, costs per surgery follow a cubic specification, implying increasing marginal costs at the practice level. Returns to experience are estimated to be quadratic, although imprecisely so, given limited observations. Due to the low response rate in the survey, there is a need to conduct further research into this topic, to provide better information to both specialists and the South African Department of Health, which sets pay packages for public sector health workers. Key words: specialist doctors, specialist practice revenues, specialist practice costs, specialist practice earnings, parametric and nonparametric regression/analysis, income/profit regression, returns to experience JEL: D21, I11 <![CDATA[<b>A comparison of inflation expectations and inflation credibility in South Africa</b>: <b>results from survey data</b>]]> This paper reports a comparison of South African household inflation expectations and inflation credibility surveys undertaken in 2006 and 2008. It tests for possible feed-through between inflation credibility and inflation expectations. It supplements earlier research that focused only on the 2006 survey results. The comparison shows that inflation expectations differed between different income groups in both 2006 and 2008. Inflation credibility differed between male and female respondents, but this difference did not feed through to inflation expectations. More periodic survey data will be required for developing final conclusions on the possibility of feedthrough effects. To this end the structure of credibility surveys should be reconsidered, as a large percentage of respondents indicated that they 'don't know' whether the historic rate of inflation is an accurate indication of price increases. <![CDATA[<b>The macroeconomic determinants of technological progress in Nigeria</b>]]> This study empirically examines the macroeconomic determinants of technological progress (total factor productivity) in Nigeria that is consistent with the endogenous growth theory. The estimations are carried out with time-series data from 1970 to 2006 using the Johansen estimation techniques. The study is distinct from most of the existing literature since it made an attempt in generating a time-varying technological progress. It employs the Kalman filter technique to determine the evolution of the Solow residual estimated from a Cobb-Douglas production function. The results conform to the existing literature that macroeconomic instability, the level of financial development, and the level of human development are highly significant determinants of technological progress in Nigeria. <![CDATA[<b>Consumer awareness and usage of islamic banking products in South Africa</b>]]> This paper investigates the level of consumer awareness and use of Islamic banking products in South Africa. A non-probability sampling method was used whereby a questionnaire was administered to 250 respondents and statistically analysed to determine the factors that are important in the choice between Islamic or conventional banks. It was found that Muslims are aware of Islamic banks, but their rate of use is low, as Muslim customers regard efficiency, lower bank charges, the availability of automatic teller machines and an extensive branch network as important factors when it comes to choosing a bank, rather than religious motivations for compliance with Islamic conventions. It was concluded that, if Islamic banks wanted to attract and retain customers and remain relevant in the South African context, they would have to develop relevant strategies designed to meet customers' needs. Religion as the sole motivation for choosing Islamic banks is inadequate. <![CDATA[<b>Application of the attitude toward enterprise (ATE) test on secondary school learners in South Africa</b>]]> The main aim of this research paper was to discuss the application of the Attitude Toward Enterprise (ATE) Test¹ developed by Kingston University, London, on secondary school learners in South Africa. A total of 1 748 usable questionnaires were gathered from grade 10 learners in the Sedibeng District and utilised for statistical analysis. Five factors with eigen-values greater than one describing the entrepreneurial attitudes of young learners were extracted during exploratory factor analysis. Tests for reliability and construct correlation produced satisfactory results to recommend the Enterprise Attitude Questionnaire for further use on young learners in South Africa. A comparison of the mean differences between the constructs for demographic variables produced statistically significant differences in a number of instances, but no visible effects or practical significance to suggest that these differences have any effect in practice. Practical recommendations are offered for further employment of the Enterprise Attitude Questionnaire in entrepreneurship research on young learners. <![CDATA[<b>Organisational commitment in a post-merger situation</b>]]> The aim of this study was to investigate organisational commitment in an organisation that had recently experienced organisational restructuring (a merger). The psychological contract that exists between employees and organisations is brittle due to many organisational changes that stem from organisational restructuring. When psychological contracts are breached, employees may experience reduced commitment to the organisation. The target population for this study consisted of all employees working at three recently-merged higher education institutions in the Nelson Mandela Metropolis (n=100) and a selfadministered questionnaire was distributed amongst staff. The results indicated that an increase in the number of positive human resource management (HRM) practices reported by respondents correlated with a decrease in violation and breach of the psychological contract, despite organisational restructuring. It was further revealed that effective management of the psychological contract is crucial during organisational restructuring, in order to maintain the commitment and loyalty of employees. <![CDATA[<b>The effects of the global recession on the work restructuring levels of managers in the South African automotive industry</b>]]> The aim of this investigation was to examine the work restructuring levels of managers in the South African automotive industry, and how these levels are affected by the global economic recession. Work restructuring was investigated from the perspective of the managers' work and family involvement levels. Data was gathered using a questionnaire that was emailed to automotive industry managers throughout South Africa. Results show that no significant gender differences occur for work involvement, family involvement, or work restructuring. A practically significant, positive relationship exists between family involvement and work restructuring. Furthermore, family involvement levels were shown not to have decreased due to the economic recession. Recommendations for organisations include implementing a gender-neutral work-family policy to assist managers in restructuring their work to accommodate family responsibilities.
