Abstract: |
We investigate the role of crude oil spot and futures prices in the process of
price discovery by using a cost-of-carry model with an endogenous convenience
yield and daily data over the period from January 1990 to December 2008. We
provide evidence that futures markets play a more important role than spot
markets in the case of contracts with shorter maturities, but the relative
contribution of the two types of market turns out to be highly unstable,
especially for the most deferred contracts. The implications of these results
for hedging and forecasting crude oil spot prices are also discussed. |
