There exists a huge international literature on the, so-called, Environmental Kuznets Curve (EKC) hypothesis, which in turn, postulates an inverted u-shaped relationship between environmental pollutants and output. The empirical literature on EKC has mainly used test for cointegration, based on...

The Feldstein-Horioka (FH) puzzle, that is the strong correlation between saving and investment in a world where obstacles to capital mobility are limited, has been studied extensively since it was exposed in 1980. Even though the theoretical and empirical literature has examined many of its...

This paper analyses the intertemporal hedging demand for stocks and bonds in South Africa (SA), the United Kingdom (UK) and the United States (US). The analysis is done using an approximate solution method for the optimal consumption and wealth portfolio problem of an infinitely long-lived...

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 develops and estimates an open economy dynamic stochastic general equilibrium model of South Africa. We devote special attention to the impact of stock price wealth effects on output and the interest rate. For this reason we adopt a perpetual youth approach, which allows for a limited...

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...

The significant change in South Africa’s trade patterns over the past two decades should affect the impact of shocks in the rest of the world on the country, since South Africa is a small open economy. We investigate the effect with the use of a global vector autoregression (GVAR) model from...

The conduct of inflation targeting is heavily dependent on accurate inflation forecasts. Non-linear models have increasingly featured, along with linear counterparts, in the forecasting literature. In this study, we focus on forecasting South African infl ation by means of non-linear models and...

We develop a structural cointegrated vector autoregressive (VAR) model with weakly exogenous foreign variables, suitable for a small open economy like South Africa. This type of model is known as an augmented vector error correction model (VECM), referred to by VECX*. We compile the foreign...

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...
