- Abstract
- Euro area inflation differentials rose sharply during the pandemic and the energy crisis but have since largely returned to previous levels. Monitoring the evolution and nature of inflation differentials is informative when assessing the transmission of the single monetary policy. This box puts the recent developments in inflation dispersion into perspective. Headline inflation and its subcomponents have all experienced considerable divergences across countries, with energy and food inflation playing a significant role. However, with a few exceptions, these temporarily sizeable differentials did not result in substantial changes in relative price levels across countries.

- Abstract
- Commodity prices co-move, but the strength of this co-movement changes over time due to structural factors, like changing energy intensity in production and consumption as well as changing composition of underlying shocks. This paper explores whether econometric models that exploit this co-movement and account for parameter instability provide more accurate point and density forecasts of ten major commodity indices viz-a-viz constant coefficient models. Improvements in point forecast accuracy are small, with predictability varying substantially across forecast horizons and commodity indices, but they are large and significant in terms of density forecasting. An economic evaluation reveals that allowing for parameter time variation and commonalities leads to higher portfolios returns, and to higher utility values for investors.
