Abstract

Désormais, le travail de l'économiste, qu'il soit théoricien ou praticien, est concentré sur la construction et l'utilisation de modèles. Les médias eux-mêmes y font sans cesse référence pour discuter les problèmes économiques contemporains. S'ils se sont imposés dans les sciences de la matière et à un moindre degré dans celles de la vie, ils pénètrent moins les sciences humaines et sociales. L'économie fait donc figure d'exception à cet égard. Pourquoi ce privilège ? A quoi donc servent les modèles en économie ? Comment se présentent-ils ? Bernard Walliser propose une analyse systématique de leurs fonctions et montre, exemples à l'appui, à quel type de problème chacune entend répondre. L'un des meilleurs spécialistes du raisonnement économique décrypte le coeur même de sa discipline. (présentation éditeur)
