Hamilton: "Understanding Crude Oil Prices"

"How would one go about explaining what oil prices have been doing and predicting where they might be headed next? This paper explores three broad ways one might approach this. The first is a statistical investigation of the basic correlations in the historical data. The second is to look at the predictions of economic theory as to how oil prices should behave over time. The third is to examine in detail the fundamental determinants and prospects for demand and supply."
