Can Simple Combination Strategies Improve Forecasts Of Swedish Inflation?
(2017) NEKP01 20171Department of Economics
- Abstract
- In this paper I use a procedure for selecting, combining and forecasting VAR models in order to improve the prediction of Swedish inflation. Three simple average combinations are evaluated with a number of tools. I conclude that a simple combination strategy improve the forecast ability and reduce the root mean square errors. The performance is an improvement over both a simple benchmark and a previous top performing individual model. This result are consistent for shorter horizons, while on longer horizons all models tend to normalize with more similar performance. Furthermore I compare the models forecast performance using the Diebold-Mariano test. I found that the com- bination models performance is not significantly different from the... (More)

The conclusion therefore is that even if the results are promising, more studies are required to fully evaluate the used procedure in order to include longer sample and for other inflation environments.
