This paper examines the time series properties of sea level rise and the surface temperature data along the Barrier Coast of Nigeria. In particular, we focus on the seasonality and the degree of persistence of the series, measured in terms of seasonal and non-seasonal unit roots along with...

This study applies the bootstrap panel causality test proposed by Kónya (2006), which accounts for both dependency and heterogeneity across countries, to test the causal link between population growth and economic growth in 21 countries over the period of 1870-2013. With regards to the...

This paper presents an efficiency assessment of selected OECD countries using a Slacks Based Model with undesirable or bad outputs (SBM-Undesirable). In this research, SBM-Undesirable is used first in a two-stage approach to assess the relative efficiency of OECD countries using the most...

This paper uses the Markov-switching multifractal (MSM) model and generalized autoregressive conditional heteroscedasticity (GARCH)-type models to forecast oil price volatility over the time periods from January 02, 1875 to December 31, 1895 and from January 03, 1977 to March 24, 2014. Based on...

The study proposes an alternative modelling specification for the real prices of gold and silver that allows the long run trend and cyclical behaviour to be modelled simultaneously by incorporating two differencing parameter in a fractional integration framework. However, we also consider the...

This study investigates the predictability of 11 industrialized stock returns with emphasis on the role of U.S. returns. Using monthly data spanning 1980:2 to 2014:12, we show that there exist multiple structural breaks and nonlinearities in the data. Therefore, we employ methods that are...

We study the response of South African monetary policy decisions to foreign monetary policy shocks. We estimate the extent of foreign monetary policy pass-through by augmenting standard Taylor rules and comparing the results within the context of a Global New-Keynesian Dynamic Stochastic General...

In this study, we apply a new recursive test proposed by Philips et al (2013) to investigate whether there exist multiple bubbles in the BRICS (Brazil, Russia, India, China and South Africa) stock markets, using monthly data on stock price-dividend ratio. Our empirical results, the first of its...

We study the effects of different levels of education on fertility in 48 sub-Saharan African countries between 1970 and 2010. The results, based on panel data analysis with fi?xed effects and instrumental variables, show how that lower education levels do not have a significant effect on...

This paper explores the quantile treatment effects of proximity to a landfill site on housing values in the Nelson Mandela Bay Metropole (NMBM), South Africa, extending the research by Du Preez and Lottering (2009) who found a negative relationship to exist between proximity to a landfill site...
