This paper applies a time-varying parameter vector autoregressive approach to estimate the relative effects of housing and stock returns on the growth rate of US consumption over time. We use annual data from 1890 to 2012 and find that at the 1- and 2-year horizons and over time, generally the...

We develop models for examining possible predictors of the return on gold that embrace six global factors (business cycle, nominal, interest rate, commodity, exchange rate and stock price factors) and two uncertainty indices (the Kansas City Fed’s financial stress index and the U.S. Economic...

Given the rapid rise and volatility of oil prices, the paper investigates the effect of oil price uncertainty on the South African manufacturing production using monthly observations covering the period 1974:02 to 2012:12. In addition, we quantify the responses of manufacturing production to...

This paper analyses the statistical properties of five major precious metal prices (gold, silver, rhodium, palladium and platinum) based the fractional integration modelling framework while identifying structural breaks. We use monthly data from 1972:1 to 2013:12. Our results indicate orders of...

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...

Oil prices have become increasingly important to determine indicators such as inflation; this in turn affects savings and investments. This paper investigates the impact of the volatility of oil prices on savings in South Africa using quarterly data covering the period 1960 to 2014. The study...

This paper examines the impact of oil price uncertainty on South Africa’s stock returns using weekly data that covers the period 1995:07:01 to 2014:08:30. The measure of oil price uncertainty is the conditional standard deviation of the one-step-ahead forecast error for the change in the price...

This paper presents an efficiency assessment of selected OECD countries using a Slacks Based Model with undesirable or bad outputs (SBM-Undesirable). In this research, SBM-Undesirable is used first in a two-stage approach to assess the relative efficiency of OECD countries using the most...

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 applies a time-varying parameter vector autoregressive (TVP-VAR) approach to estimate the relative effects of housing and stock prices on US consumption over time. We use annual data from 1890 to 2012 and find that over different horizons and over time, generally the housing price...
