|December 2016||Commodity Price Forecasts, Futures Prices and Pricing Models|
with Cristobal Millard, Hector Ortega, Eduardo S. Schwartz: w22991
Even though commodity pricing models have been successful in fitting the term structure of futures prices and its dynamics, they do not generate accurate true distributions of spot prices. This paper develops a new approach to calibrate these models using not only observations of oil futures prices, but also analysts’ forecasts of oil spot prices.
We conclude that to obtain reasonable expected spot curves, analysts’ forecasts should be used, either alone, or jointly with futures data. The use of both futures and forecasts, instead of using only forecasts, generates expected spot curves that do not differ considerably in the short/medium term, but long term estimations are significantly different. The inclusion of analysts’ forecasts, in addition to futures, instead of only futures prices...
|June 2013||Commodity and Asset Pricing Models: An Integration|
with Ivo Kovacevic, Eduardo S. Schwartz: w19167
We present a simple methodology that integrates commodity and asset pricing models. Given current evidence on the financialization of commodity markets, valuable information about commodity risk premiums can be extracted from asset pricing models and used to substantially improve the estimates of expected spot prices provided by current commodity price models. The methodology can be used with any pair of commodity and asset pricing models. An implementation of the methodology is presented using the Schwartz and Smith (2000) two-factor commodity price model and the CAPM. Reasonable expected spot prices are obtained without negative consequences in the model's fit to futures prices.
