PRICE RISK MANAGEMENT FOR PEANUT MEAL

Peanut meal is cross-hedged with soybean meal using peanut meal cash prices and soybean meal futures prices. Hedge rations are obtained for short- vs. long-term data sets. Evaluation indicates positive gains for cross-hedged poultry/peanut producers, and that soybean meal futures can be used as a cross-hedging vehicle for peanut meal.Demand and Price Analysis, Marketing,

CROSS-HEDGING COTTONSEED MEAL

This study examines the feasibility of cross-hedging cottonseed meal with soybean meal futures. The Bayesian tests for market efficiency on the cash and futures price data soundly rejects the presence of nonstationary root. The simple linear regression of cottonseed meal cash prices on soybean meal futures provides a direct price movement relationship. Using the estimated hedge-ratios, the net realized prices are calculated for seven different cash markets. The net realized prices exhibit risk efficiency superior to cash pricing. The empirical analyses suggest that soybean meal futures can be used as a potential cross-hedging vehicle for cottonseed meal.Marketing,

Change in fatigue behavior of asphalt hot mixes produced with asphalt rubber binders

Fatigue life of asphalt hot mixes is given as a function of both stiffness and tensilestrains induced in the bottom of the wearing courses of flexible pavements. In conventional as-phalt hot mixes the increase of stiffness leads to a decrease of fatigue life. However, this work shows that there is an increase of both fatigue life and stiffness of asphalt rubber hot mixes in comparison with the asphalt hot mixes produced with straight binders. In this work laboratory tests were performed in asphalt hot mixes with dense and gap gradation produced with straight binder (AC 50/70) and asphalt rubber binder manufactured by the wet process. Resilient mod-ulus and fatigue life tests under four point bending procedure were used to determine the me-chanical behavior of studied mixtures. The results show that the use of asphalt rubber binder produced an increase of both fatigue life and stiffness of the studied mixtures
