Time-to-build, time-to-produce, and inventory have important implications for asset prices and quantity dynamics in a general equilibrium model with recursive preferences. Time-to-build captures the delay in transforming new investments into productive capital, and time-to-produce captures the...

​We develop and estimate a multifactor affine 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...
