"In this paper, we evaluate the proposition that market structure, including supply and demand elasticities, plays a significant role in influencing equilibrium price dynamics. We show that the more inelastic the demand and/or supply of a commodity is, the more price risk will be faced by producers of that commodity. In general one can expect greater volatility from commodities with both demand and supply being inelastic, and the least when they are both elastic. We illustrate how the elasticities of supply and demand can impact the prices of contingent claims on agricultural commodities including revenue insurance."
