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...

It is necessary for multilateral trade negotiations to include exceptions to accommodate politically sensitive sectors. However, given the highly concentrated distribution of agricultural protection, too many exceptions put at risk the objectives of World Trade Organization. This paper assesses...

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...

To better understand the production of biofuels derived from lignocellulosic feedstock, we investigate the interplay between the agricultural sector and a biofuel facility, at the local level. More specifically, we investigate the economic and technological viability of a bioenergy facility over...

Many countries adjust their trade policies counter cyclically with foodprices,to the extent that the use by numerous foodexporters of export restrictions has occasionally threatened the foodsecurity of food importing countries.These tradepolicies are inconsistent with the terms-of-trade...

When food prices spike in countries with large numbers of poor people, public intervention is essential to alleviate hunger and malnutrition. For governments, this is also a case of political survival. Government actions often take the form of direct interventions in the market to stabilize food...

Given the highly concentrated distribution of agricultural protection, allowing in the negotiations too many exceptions through sensitive products puts at risk the objectives of World Trade Organization. This issue is difficult to analyze with the commonly used applied trade models, because they...
