The paper investigates the bank-lending channel (BLC) of monetary policy in South Africa using quarterly bank-level data for the period 2000Q1-2004Q4. Capital adequacy and bank size are used as indicators for information problems faced by banks when they look for external finance. Utilising...

The oil price-inflation relationship has been at the center of attention among economists and policy makers, especially after 1970’s oil shocks that resulted to a significant increase in the inflation rate in number of countries around the world. In this study, we aim to investigate the...

-directional causality between money and income. When we apply Granger Causality tests we find that income Granger causes money. The … causality disappears when we add interest rates. Next when we use an Error Correction Model the results of the traditional … Granger causality tests hold true in the bivariate system. But, we observe bi-causality under longer lag specifications, and …

This paper analyses the extent to which the South African Reserve Bank (SARB) uses the repo rate in response to exchange rate depreciations. We use a Vector Autoregression to model the simultaneous linkage between the real effective exchange rate and the policy rate. A combination of short-run...

This paper evaluates the hypothesis of long-run super-neutrality of money (LRSN) within the context of the South African economy. The long-run impact of inflation on the interest rate and subsequently, output is estimated by employing a trivariate structural vector autoregression model. The...
