This paper investigates whether unobserved asymmetries can account for irregularities in the Fisher effect for the exclusive case of South Africa. This objective is attained by investigating unit roots within a threshold auto-regressive (TAR) models and estimating a threshold vector error...

In this paper, a momentum threshold autoregressive (MTAR) model is used to evaluate nonlinear equilibrium reversion between unemployment and economic growth for South African data between the periods 2000–2013. To attain this objective we estimate the first-difference and the gap model...

This study undertakes an examination of asymmetric adjustment effects between electricity consumption and economic growth in South Africa using quarterly data collected from 1983Q1 to 2013:Q4. In our study, we employ a momentum-threshold co-integration method to examine the long-run equilibrium...

This study deviates from the conventional use of a linear approach in testing for the efficiency market hypothesis (EMH) for the Johannesburg Stock Exchange (JSE) between the periods 2001:01 to 2013:07. By making use of a threshold autoregressive (TAR) model and corresponding asymmetric unit...

This study undertakes an examination of asymmetric co-integration adjustment in Okun’s law for South Africa between the periods of 2000-2013. This objective is tackled through the use of momentum threshold autoregressive (MTAR) econometric framework. Contrary to conventional theory, the...

This study examines threshold effects of inflation on economic growth for the Zambian economy using quarterly data collected between 1998 and 2011. This objective is tackled through the use of a threshold autoregressive (TAR) model and the conditional least squares (CLS) estimation technique. As...

Can the South African Reserve Bank’s (SARB) substantially control inflation within their set target of 3-6 percent? We sought to investigate this phenomenon by examining multiple threshold effects in the persistence levels of quarterly aggregated inflation data collected between 2003 and 2014....

Purpose: This purpose of our paper is to examine asymmetric co-integration effects between nutrition and economic growth for annual South African data from the period 1961-2013. Design/methodology/approach: We deviate from the conventional assumption of linear co-integration and pragmatically...

This paper investigates asymmetric co-integration and causality effects between financial development and economic growth for South African data spanning over the period of 1992 to 2013. To this end, we make use of the momentum threshold autoregressive (MTAR) approach which allows for threshold...

Purpose: This purpose of this study is to examine the asymmetric adjustment effects for the purchasing power parity (PPP) for South Africa against her main currency trading partners; namely, the US, the UK, the Euro area, China and Japan. Design/Methodology/Approach: This study presents a...
