T. Vukina et Jl. Anderson, A STATE-SPACE FORECASTING APPROACH TO OPTIMAL INTERTEMPORAL CROSS-HEDGING, American journal of agricultural economics, 75(2), 1993, pp. 416-424
Cross-commodity hedging between fishmeal and soybean meal is investiga
ted. The approach uses successively updated out-of-sample forecasts to
approximate subjective price expectations, and forecast error varianc
e-covariance matrices to measure risk. Forecasts are generated by stat
e-space models of vector-valued time series. In a stationary environme
nt, uncertainty reduces to the difference between the historical autoc
ovariance of the random process and the variance-covariance of out-of-
sample forecasts. Results indicate that weakly risk-averse agents can
increase average marketing returns within acceptable risk levels by co
mbining information from price forecasting models with an appropriate
hedging strategy.
