- Description: South Africa has experienced a high and rising burden of non-communicable diseases (NCDs) and lifestyle risk factors over the past decade. Health as a category of human capital is generally ex-pected to influence an individual’s labour supply and productivity. Despite the increasing burden of non-communicable diseases, the high rate of economically inactive population and persistent wage inequalities in South Africa, there is limited empirical research on the effect of NCDs on labour force participation, employment status and wage differentials. Given this, the main object-ive of this study was to determine the effects of NCDs on three labour market outcomes: labour force participation, employment status and wage differentials in South Africa. This was divided into three major analytical objectives. Data used was extracted from the five waves of the National Income Dynamics Study, a nationally representative survey collected by the South African Labour and Development Research Unit (SALDRU). Several econometric tests, including cross-sectional data analysis, panel data analysis and the Blinder-Oaxaca decomposition methods, were used in the study. The first analytical objective focused on estimating the effect of lifestyle risk factors on labour force participation through NCDs by gender. Endogenous multivariate probit models with a recur-sive simultaneous structure were employed as a method of analysis. The empirical findings suggested that NCDs and associated risk factors have detrimental effect on labour force participation. The analysis was further expanded to analyse the effect of gender differences, considering that the effect of NCDs may be gender-specific. The results revealed that the effect of stroke and heart diseases were significant only for men, while diabetes and high blood pressure were only significant for women. The results also emphasised the significant indirect influence of obesity, physical inactivity, and alcohol consumption on labour force participation through NCDs, especially for men. The second analytical chapter focused on investigating the effect of NCDs on employment status – that is, those employed, unemployed and economically inactive in the population of South Africa by gender. The estimation technique known as generalised linear latent and mixed methods (GLLAMM) was employed to fit the multinomial logit model with correlated random intercept. The findings suggest that NCDs affect the economically inactive population significantly relative to those employed, and the magnitude is larger for women than for men. There was no significant difference found in the effect of NCDs on the unemployed relative to the employed segment of the population. In addition, the results revealed gender differences on the effect of NCDs on employment status and that stroke had a significant influence on the employment status of both sexes, while heart diseases had significant influence only in men, whereas diabetes had significant effects only in women. The last analytical chapter focuses on estimating the effect of NCDs on wage differentials in South Africa by gender. The recentred influence function regression model and Blinder-Oaxaca de-composition with RIF were used in the chapter. The empirical results revealed that the effect of NCDs on earnings differ by gender. It was found that women with NCDs earn less than those without NCDs, while men with NCDs were found to earn more than their counterparts without NCDs. The results further revealed that women with NCDs suffer from wage discrimination in South Africa. The policy implications of this study are gender-specific. The results highlight the necessity for undertaking a massive awareness campaign regarding the prevention and control of NCDs, espe-cially among women. This can be achieved through specific female health programmes, including maternal healthcare. The findings of the study imply largely that calls for gender-responsive health approaches which take into account gender-specific needs and priorities should be promoted, compared to a blanket approach. In addition, there is a need for the government to complement education policies to promote labour market outcomes. Policies aimed at increasing access to education should continue to improve access to higher education and so to enhance participation in the labour force and reduce wage gaps. , Thesis (PhD) -- Faculty of Management and Commerce, 2020

- Description: Rural-urban migration is historically connected to industrialization, urbanization and economic growth. The Lewis model is one of the development theories which provide a good framework of explaining the ways in which the fruits of economic development are spread. Previous studies done in Lewis model in South Africa are still minimal and are only related to the mining sector. Understanding the Lewis labour surplus model in the smallholder agricultural sector is very crucial as agriculture is one of the industries that contribute to the GDP of the country. The application of the Lewis model in the agricultural sector will contribute modestly to available knowledge on labour transition, clarify the ongoing argument on the broad application of the Lewis labour surplus model and more importantly is the need to tease out factors that confirm its validity to the given environment. Thus, the research examines the applicability of the Lewis labour surplus model in the smallholder agricultural sector of the Eastern Cape. It first describes the rate of rural urban migration, causes of rural-urban migration and determines the impact of rural-urban migration on agricultural production.The study was carried in Nkonkobe and Mnquma local Municipalities. Both local municipality were purposively selected because of the high numbers of youth known to have migrated to the urban centres.This study employed a cross-sectional research design. Data was collected at one point in time. Multistage random sampling technique was employed to arrive at the sample size of the study. Data was analysed using descriptive and econometric models. Linear regression model was used to examine the causes of rural urban migration and T-test was also used to test the wage rate difference between rural and urban areas. Lastly Cobb Douglas model was used to test the impact of rural-urban migration on agricultural production. The findings of this research showed that rural urban migration is caused by higher wages, employment opportunities, lack of infrastructure and access to productive land. The results also indicated that urban areas have higher wages than rural areas. Lastly this study provides evidence that the loss of labour through increases in the existing rural-urban migration following rapid urbanizations has an impact on agricultural production. The government should formulate effective policy making in tackling the problems that force people to leave their rural origin and narrowing the development gap between urban and rural areas through the introduction of rural development strategies and effective urban management. , Thesis (MSc) -- Faculty of Science and Agriculture, 2015
