The paper examines the relationship between energy consumption and economic growth for South Africa for the period 1971-2009. Most studies examining this relationship do assume that it remains constant through the years; however the reality might be different since many factors can affect the...

The main purpose of this paper is to investigate the causal relationship between knowledge (research output) and economic growth in US over 1981 to 2011. To overcome the issues of ignoring possible instability and hence, falsely assuming a constant relationship through the years, we use...

The aim of this paper is to analyse the causal link between monthly oil futures price changes and a sub-grouping of S&P 500 stock index changes. The causal linkage between oil and stock markets is modelled using a vector autoregressive model with time-varying parameters so as to reflect changes...

One characteristic of many macroeconomic and financial time series is their asymmetric behaviour during different phases of a business cycle. Oil price shocks have been amongst those economic variables that have been identified in theoretical and empirical literature to predict the phases of...

This paper revisits the causality relationship between electricity consumption and economic growth in South Africa for the period 1971-2009 using annual data and takes into consideration time variation in causal relationships using bootstrap rolling Granger non-causality tests. Full-sample...

This article contributes to the existing empirical literature by examining the spillovers across price inflation and agricultural commodity prices for the case of Nigeria. To achieve this objective, we employ the Diebold and Yilmaz (Int J Forecast 28(1):57-66, 2012) spillover index....

This paper investigates the dynamic causal link between exports and economic growth using both linear and nonlinear Granger causality tests. We use annual South African data on real exports and real gross domestic product from 1911-2011. The linear Granger causality result shows no evidence of...

This paper makes two contributions to the growing literature on the military expenditureeconomic growth nexus. It provides a case study of a developing country, South Africa, and considers the possibilities of structural breaks in the relationship, applying newly developed econometric methods....
