This paper examines the relationship between innovation and export performance for African firms. We use Tobit simultaneous equation full information maximum likelihood (FIML) model with selection on a crosssectional dataset from the World Bank’s Enterprise Surveys for 28 African economies. The...

We consider the effects of climate change on seasonally migrant populations that herd livestock – i.e., transhumant pastoralists – in Africa. Traditionally, transhumant pastoralists benefit from a cooperative relationship with sedentary agriculturalists whereby arable land is used for crop farming...

South Africa successfully reduced smoking prevalence by substantially increasing tobacco excise tax and therefore real cigarette prices between 1993 and 2010. Tobacco market structure changed in 2010 following the entry of local tobacco companies and the introduction of cheaper cigarette brands...

This article investigated income per capita convergence in the Southern African Development Community (SADC) over the period 1980-2017 in a non-linear time-varying coefficients framework. The findings of the study suggested no overall income convergence in the SADC region, but evidence supporting the...

We develop a new dataset of bank-level balance sheets data to estimate bank-level funding costs. These estimates are useful for monitoring of funding pressures and other risks to the banking sector as well as understanding the impact of prudential regulations and market conditions on the...

Homeownership by the lower and middle-income households is crucial to create wealth, particularly for South Africa with high levels of economic and wealth inequality. However, scholarship has paid little attention to how income affects the affordable housing market segment despite its systemic...

This study examines the complex relationship between carbon emissions and technological progress in a sample of 60 countries, divided into four categories based on their per capita income between the periods of 1989-2018. For robustness purposes and due to the broad definition of technology, we use...

We estimate that since 1701, South Africa has experienced 163 years of per capita growth of more than 1 per cent a year. These expansions include 55 years of sustained per capita GDP growth of more than 3 per cent a year – windfall periods that were related to the discovery of diamonds and gold,...

A panel data analysis of financial inequality was conducted using the PSTR model to determine the threshold level at which excessive financial development worsens inequality. The results reveal evidence of a nonlinear effect between financial development and income inequality where the optimal...
