The theoretical framework of seasonal price analisis is an inter-temporal market model of assets with several storing agents, farmers, traders or processing agents, depending on situations. The simplified model underlines the role of each agent and the impact of variables such as liquidity constraints, asymmetric information and risk aversion on price stability. Several situations of complementarity and destabi- lization among agents are identified and the consequences of those interactions on seasonal price patterns are analyzed. This representation helps design public policies and target them on those agents whose contribution to price stabilization is the largest.
