This paper considers four competing propositions to explain the convex relationship between inventories and the cost-adjusted basis called the 'Working curve' - the convenience yield, the risk premium, data aggregation and the imbedded options value inherent to a futures contract. We use 70...

This paper revisits the asymmetric effect of the basis on commodity spot and futures price volatilities documented by Kogan, Livdan and Yaron (2008) and Lien and Yang (2008). Kogan et al. (2008) show both theoretically and empirically that, for a non-storable consumption good, the relationship...

This paper considers four competing propositions to explain the convex relationship between inventories and the risk-adjusted spread called the 'Working curve': the convenience yield, the risk premium, data aggregation and the imbedded options value inherent to a futures contract. We use 70...

This paper proposes that, when modeling for the relation between the convenience yield and current scarcity, time to maturity and time to harvest should interact with current scarcity. In implementing this idea we compare three models for current scarcity, based on inventory levels, the spot...

We propose to use two futures contracts in hedging an agricultural commodity commitment to solve either the standard delta hedge or the roll-over issue. Most current literature on dual-hedge strategies is based on a structured model to reduce roll-over risk and is somehow difficult to apply for...
