Macroeconomics: Production

Productivity estimates for South Africa from CES production functions

This paper provides estimates of the elasticity of substitution and total factor productivity (TFP) for South Africa. Estimates are based on constant elasticity of substitution (CES) production functions. Estimates of potential output and the output gap implied by different CES model specifications are also compared to those from other models.

Production, Inequality and Poverty linkages in South Africa

The Kuznets inequality-development hypothesis can be tested with time-series data rather than the cross-section analyses found in earlier literature. Single-country time-series analysis cannot be done without addressing endogeneity between output and inequality. South Africa has been under-researched in this area due to a lack of data. Recent data released by the Presidency of South Africa makes such analysis possible. Besides, the use of a single inequality index in such a multiracial society is likely to capture only average effects.

Social Ingredients and Conditional Convergence in the Study of Sectoral Growth

In this research article, we investigate the improved modelling ability and the outstanding policy advocacy of infusing health and education in sectoral growth equations of the South African economy. Our findings not only include improved and dependable modelling results but also provide distinct estimates of the returns on investment in health and education per sector using Iterative Seemingly Unrelated Regressions techniques. Additionally, this paper provides a theoretical description of the productivity effects of HIV/AIDS using sectoral equations.
