    We analyze the determinants of daily futures price volatility in corn, soybeans, wheat, and oats markets from 1986 to 2007. Combining the information from simultaneously traded contracts, a generalized least squares method is implemented that allows us to clearly distinguish among time-to-delivery effects, seasonality, calendar trend, and volatility persistence. We find strong evidence of time-to-delivery (Samuelson) effects and systematic seasonal components with volatility increasing prior to harvest times— an indirect confirmation of the theory of storage.futures markets, Samuelson effect, seasonality, time to maturity, volatility, Crop Production/Industries, Risk and Uncertainty,

    Volatility Persistence in Commodity Futures:Inventory and Time-to-Delivery Effects

    Most financial asset returns exhibit volatility persistence. We investigate this phenomenon in the context of daily returns in commodity futures markets. We show that the time gap between the arrival of news to the markets and the delivery time of futures contracts is the fundamental variable in explaining volatility persistence in the lumber futures market. We also find an inverse relationship between inventory levels and lumber futures volatility.volatility persistence, theory of storage, volatility, futures markets, lumber, Agricultural Finance,
