This paper finds that the long-term co-movement of commodity prices is driven by economic relationships, such as production, substitution, and complementary relationships. Such relationships imply that the convenience yield of a given commodity depends on its relative scarcity with respect to...

<section xml:id="fut21649-sec-0001"> This study extends the maximal affine models of single assets to a multi‐commodity setup. We show that the correlated version of maximal affine models for a single commodity is no longer maximal for multiple commodities. In the maximal model, the convenience yield of a certain commodity could...</section>

This paper shows that economic linkages among commodities create a source of long-term correlation between futures returns. We extend the theory of storage to a multi-commodity level and find that the convenience yield of a commodity depends on its relative scarcity with respect to other related...
