In times of highly volatile commodity markets, governments often try to protect their populations from rapidly-rising food prices, which can be particularly harsh for the poor. A potential solution for food-deficit countries is to hold strategic reserves, which can be called on when...

There are two explanations for agricultural price dynamics. One follows cobweb logic and models fluctuations driven by expectation errors but emphasises that these expectations create complex dynamics and possibly chaos. The other stems from the rational expectations tradition of dynamics driven...

Cette thèse propose une analyse des politiques de stabilisation des prix alimentaires dans les pays pauvres. Afin de représenter la situation dans ces pays, nous considérons dans un modèle de stockage à anticipations rationnelles que les consommateurs ne peuvent pas s'assurer contre le...

This paper compares numerical methods for solving the competitive storage model. Because storage implies a nonnegativity constraint on stocks, the solution methods must be considered carefully. The model is solved using value function iteration and several projection approaches, including...

This paper analyzes the use of storage and trade policies to achieve food price stabilization in a small open developing country. Optimal stabilization policies are identified using a rational expectations storage model with risk-averse consumers and incomplete markets. Without public...

This paper proposes a framework for designing optimal food price stabilisation policies in a self-sufficient developing country. It uses a rational expectations storage model with risk-averse consumers and incomplete markets. Government stabilises food prices by carrying public stock and by...

This article compares different policies in a rational expectations storage model with risk-averse consumers and missing insurance markets calibrated to represent a developing country. We consider an optimal storage policy under discretion and two optimal simple rules, a constant private storage...
