Book excerpt: Using survey-based monthly data over thirty years, we show that oil price expectations for 3- and 12-month horizons are not rational implying that the ex-ante oil risk premium is a more relevant concept for decision making than the widely popular ex-post premium. Using a portfolio choice model framework, we derive each risk premium as a product of the price of risk and the expected volatility of oil return, these two components being time varying and horizon-dependent. A state-space model of risk premiums, where the risk prices are represented as stochastic unobservable components and where expected variances are proxied as weighted averages of past instantaneous variances, is estimated using Kalman filtering. We find that our model adequately represents the ex-ante oil risk premiums dynamics, from which the representative investor appears to be mostly risk seeking at short horizons and mostly risk averse at longer horizons. A state-dependent interpretation of our risk premium patterns shows consistency with the predictions of the prospect theory. We also show that our risk prices are correlated with a number of economic and oil market-related factors, and find that an upward sloped term structure of oil risk premiums prevails in average over the period.
