This paper examines the causal relationship between economic policy uncertainty (EPU) and equity market uncertainty (EMU) in the US using linear and nonlinear Granger causality tests. We use daily data on the newly developed indexes by Baker et al. (2013) covering 1985:01:01 to 2013:06:14....

In this paper we examine the real estate returns predictability employing US REITs and a set of possible predictors for the period January 1991 to September 2013. To this end we employ several forecasting models to test for REITs predictability under a flexible framework that captures parameter...

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...

Following the 2007-2009 global recession, economic policy uncertainty and its effect on economic recovery has become an issue of interest in academic, media as well as policy-making circles (Baker et al., 2013). Given this backdrop, we investigate causality between economic policy uncertainty in...

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...

The relationship between oil and the price level has always garnered attention from policy makers and role players in the market. Periods of high oil price volatility is thought to have negative repercussions for domestic price levels in an oil importing country. Research in the past has shown...

This study investigates the asymmetric and time-varying causality between inflation and inflation uncertainty in South Africa within a conditional Gaussian Markov switching vector autoregressive (MS-VAR) model framework. The MS-VAR model is capable of determining both the sign and direction of...

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 investigates the impact of macroeconomic effects of uncertainty on the conditional volatility of US-listed Real Estate Investment Trusts (REITs). To this end we employ three widely accepted US REITs indices and the two uncertainty indices constructed by Baker et al. (2013). Our sample...

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...
