The interaction between food prices and oil prices

This paper provides a statistical methodology to estimate the impact of oil price uncertainty on food prices. In doing so, it examines the joint impact of oil price and food price uncertainties and their correlation on the food price. Also, the theoretical model was applied to the oil-based Trinidad and Tobago and the empirical results confirm the theoretical predictions. The empirical results indicate that a higher oil price increases food price. Also, a higher oil price volatility yields a higher food price. Moreover, an increase in the oil supply reduces the food price. (C) 2010 Elsevier B.V. All rights reserved.
