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...

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...

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...

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...

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...

The 2006 sudden and immense downturn in U.S. House Prices sparked the 2007 global financial crisis and revived the interest about forecasting such imminent threats for economic stability. In this paper we propose a novel hybrid forecasting methodology that combines the Ensemble Empirical Mode...

This paper investigates whether changes in monetary transmission mechanism respond to variations in asset prices. We distinguish between bull and bear markets and employ a TVP-VAR approach with stochastic volatility to assess the evolution of the monetary policy in relation to housing and stock...

This paper studies the interplay of fiscal policy and asset price returns of the United States in a time-varying-parameter vector autoregressive model. Using annual data from 1890 to 2013, we study the effects of dynamic shocks to both fiscal policy and asset returns on asset returns and fiscal...
