Popis: We develop and estimate a multifactor a¢ ne model of commodity futures that allows for stochastic variations in seasonality. We show conditions under which the yield curve and the cost-of-carry curve adopt augmented Nelson and Siegel functional forms. This restricted version of the model is parsimonious, does not suer from identi…cation problems, and matches well the yield curve and futures curve over time. We estimate the model using heating oil futures prices over the period 1984-2012. We …nd strong evidence of stochastic seasonality in the data. We analyze risk premia in futures markets and discuss two traditional theories of commodity futures: the theory of storage and the theory of normal backwardation. The data strongly support the theory of storage.
