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...

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 causality between oil prices and the prices of agricultural commodities in South Africa. We use daily data covering the period April 19, 2005 to July 31, 2014 for oil prices and the prices of soya beans, wheat, sunflower and corn. The test for Granger causality in...

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 literature on causality takes contradictory stands regarding the direction of causal relationships based on whether one uses temporally aggregated or systematically sampled data. Using the relationship between a nominal target and the instrument used to achieve it, as an example, we show...

This paper looks into the changes of the black market premium for foreign exchange in Zimbabwe. Generally, the black market for foreign exchange arises as a direct consequence of the adoption of exchange rate controls in many developing economies facing substantial macroeconomic imbalances....

This paper investigates the causal relationship between export and economic growth for Botswana, using quarterly data for the period 1995.1-2005.4. It uses two measures of economic growth namely, GDP and GDP excluding export. When GDP is used as a proxy for economic growth, the investigation...

This paper investigates the causal relationship between asset prices and per capita output across 50 US states and the District of Columbia over 1975 to 2012. A bootstrap panel Granger causality approach is applied on a trivariate VAR comprising of real house prices, real stock prices and real...

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 estimates Bayesian Vector Autoregressive (BVAR) models, both spatial and non-spatial (univariate and multivariate), for the twenty largest states of the US economy, using quarterly data over the period 1976:Q1 to 1994:Q4; and then forecasts one-to-four quarters ahead real house price...
