Abstract
Linkages between agricultural commodity and energy prices have become more complex with increased ethanol production. The concern is whether the new corn-ethanol links lead to volatilityspillover transmission between food and energy prices. We investigate asymmetric volatility spillovers between oil, corn, and ethanol prices using a BEKK-multivariate-GARCH approach. Additionally, we use daily, weekly, and monthly futures prices to examine whether the use of different-frequency data leads to inconsistent results. The results support the existence of asymmetric volatility transmission between corn and ethanol prices. Furthermore, the volatilityspillover effects are different for the different-frequency prices, and positive and negative price changes generate inconsistent results.
