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....

This paper investigates the direction of causal relationship between taxes and expenditure in South Africa, using quarterly data for the period 1960:1-2006:2, and annual data for 1960 to 2005. For both frequencies, gross domestic product and government debt are included in the VAR system as...

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 causal link between tourism receipts and GDP has recently become a major focus in the tourism economics literature. Results obtained in recent studies about the causal link appear to be sensitive with respect to the countries analysed, sample period and methodology employed. Considering the...

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 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...

This paper investigates the causality between oil price and economic uncertainty in India. In order to test for this relationship, we collect data on the Brent crude oil price as well as the crude oil ETF volatility index. We also use the policy-related economic uncertainty index as well as the...
