The paper develops an adaptive model of perishable commodity dissipation based on the individual's price expectations and risk perception. A two-step, state-space procedure for modeling nonstationary time series is presented. The method combines an impulse response model for estimating deterministic components with an innovations model for the remaining stationary stochastic noise. Combined parameters are used to generate forecasts and to derive a measure of risk in a nonstationary price environment. Defined as the variance (covariance) of out-of-sample forecast error, the measure of risk is the difference between the historical estimate of the stationary noise auto-covariance and the variance (covariance) of out-of-sample forecasts.
