Abstract

[eng] Computable general equilibrium models, risk, and the place of agriculture within the economy : an application to Poland and Hungary . In order to discuss the place of agriculture in growth, as well as the economic relationships between sectors, general equilibrium models of Hungarian and Polish economies are built up. Because price stabilisation policies are at stake in these countries, emphasis is put on introducing risk consideration into the equilibrium. Because growth is an important issue, the models are made recursive, by making current stocks dependant upon past year flows. It is shown that many conclusions, such as the large benefits from trade, which seem firmly founded when risk is not considered in models, mus be revisited when it is. [fre] Un modèle calculable d'équilibre général est construit pour étudier la place de l'agriculture, et les interactions entre les différents secteurs, dans la croissance des économies polonaise et hongroise. Le désir de pouvoir étudier des politiques comme la stabilisation des prix implique que le modèle tienne compte explicitement du comportement des producteurs vis-à-vis du risque. Par ailleurs, la question étant posée dans une perspective dynamique, le temps est introduit par l'intermédiaire de relations de récurrence, qui relie les stocks d'une année aux flux de l'année précédente. On se rend compte alors que les conclusions optimistes sur les possibilités de croissance de ces pays, et sur les bienfaits du libéralisme, telles qu'elles ressortent de modèles d'équilibre statique, sont peut-être moins justifiées qu'elles n'en ont l'air.
