This paper examines the dynamic causal relationship between global oil price and South Africa’s food price using both full sample and time varying Granger causality tests. Monthly data from 2000:1 to 2014:6 is used. Result from the linear full sample Granger causality result shows no evidence...

The aim of this paper is to investigate the causal relationship between agricultural prices in South Africa and global oil prices. A nonlinear Granger causality test based on moment conditions, introduced by Nishiyama et al (2011) is employed and we find that there is indeed a causal...

In this paper, we analyze symmetric and asymmetric causal relationship between energy consumption and economic growth in time and frequency domains, using annual data covering the period of 1965-2012. In general, our results tend to suggest that energy consumption causes growth, especially the...

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...

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 double dividend hypothesis contends that environmental taxes have the potential to yield multiple benefits for the economy. However, empirical evidence of the potential impacts of environmental taxation in developing countries is still limited. This paper seeks to contribute to the...

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...

The recent commodity price boom has spurred interest to understand determinants of commodity price movements. This paper investigates the causal relationship between oil prices and the prices of 25 other commodities, which include both metals and agricultural products, in the presence of...

This study applies the recently developed bootstrap panel causality test proposed by Kónya (2006) to investigate the causal link between happiness and smoking using per capita cigarette consumption and happiness index for 5 countries (i.e. Japan, France, Germany, the UK, and the US) over the...
