This paper develops a Bayesian Vector Error Correction Model (BVECM) for
forecasting inventory investment in South Africa. The model is estimated using
quarterly data on actual sales, production, unfilled orders, price levels and interest rates,
for the period of 1978 to 2000. The out-of-sample-forecast accuracy obtained from the
BVECM, over the forecasting horizon of 2001:1 to 2003:4, is compared with those generated
from the Classical variant of the VAR and the VECM, the Bayesian VAR, and the ECM of
inventory investment developed by Smith et al. (2006) for the South African economy.
The BVECM with the most tight prior outperforms all the other models, except for a relatively
tight BVAR. This BVAR model also correctly predicts the direction of change of inventory
investment over the period of 2004:1 to 2006:3.
This paper uses a version of Hansen's (1985) Dynamic Stochastic General Equilibrium (DSGE) model to forecast the South African economy. The calibrated model, based on annual data over the period of 1970-2000, is used to ...

This paper investigates the ability of the Dornbusch (1976) sticky-price model for the
nominal metical-rand exchange rate, over the period 1994:1-2005:4 in explaining the
exchange rate movements of Mozambique. Based on ...

The study evaluates the forecasting ability of models of South Africa’s real fixed business non-residential investment spending growth over the recent 2003:1–2011:4 out-of-sample period. The forecasting models are based ...
