Analyse d'un marché agricole et des structures de production par la modélisation dynamique. Le marché des vins de table et la viticulture du Languedoc-Roussillon au XXe siècle

Analysis of an agricultural market and structures of production by means of "dynamic model-building": The Market for tablewines and viticulture in Languedoc-Roussillon in the 20th century The distortions affecting most agricultural markets have had serious consequences for the evolution of structures of production in the 20th century. With respect to the market for table-wines, the consequences of viticultura crises were felt with particular acuteness in the region of Languedoc-Roussillon ; these included economic effects (e.g., periodic destruction of a portion of the production, a restructuring of land holding) and social effects (e.g., rural exodus and reshaping of the rural environment). The abandonment of the imposed political policy of a controlled market has, during the past decade, accellerated this evolution. The consequences of market crises have often been analysed in a static manner on the basis of agricultural studies and censuses. In this article, the utilization of "dynamic model-building" on a computer contributes to understanding these economic and social phenomena in the context of their historical development. The authors analyse the behavior of the following two models as applied to the viticultural crises : 1. The market model of the years preceding the 1950's, which explains the permanence of the balance between small and large producers in Languedoc-Roussillon. 2. The contemporary model, showing the fundamental role of the market in the rapid evolution of structures of production which resulted in the elimination or marginalization of less competitive producers.Pech Rémy, Marcant Olivier.
