The expected net return to storage is conventionally calculated as the expected change in price over the storage period minus the cost of storage. However, this value is almost always negative, thus raising the question why would anyone store. Numerous explanations have been proposed, but none...

An updated supply of storage equation is estimated to reflect recent developments in the theoretical and empirical literature. Among the findings is an inverse relationship between storage cost adjusted price spread and a proxy measure of convenience yield, and a curvilinear relationship between...
