The Influence of Technology and Demand Conditions on Future Prices and Hedging


  • Weller, Paul
  • Yano, Makoto


We examine the determination of spot and futures prices in rational expectations equilibrium in a model with three groups of agents, agricultural producers, processing firms and speculators. We find necessary and sufficient conditions for producers to be short, expected future spot price (normal backwardation). the conditions impose plausible restrictions on demand elasticities and on the elasticity of substitution in the processing technology. We use a new techniques of analysis which, in contrast to much of the literature does not require restrictive assumptions to be imposed upon the structure of preferences.
