Résumé en anglais
We reinvestigate the issue of excess comovements of commodity prices initially raised in Pindyck and Rotemberg (1990). While Pindyck and Rotemberg and following contributions consider this issue using an arbitrary set of control variables, we develop our analysis using recent development in large approximate factor models so that a richer information set can be considered. This ensures that fundamentals, a necessary concept for any excess comovement analysis, are modelled as well as possible. We then consider different measures of correlation to assess comovement and we provide evidence of excess comovement for a set of 8 seemingly unrelated commodities. Our results indicate that excess comovement in returns does exist even when the issue of heteroscedasticity is considered. We extend our analysis to the excess comovement of volatilities and show that, contrary to the case of returns, comovement vanishes once the effect of fundamentals have been taken out.
