Abstract

We extend the macroeconomic literature on Ss‐type rules by introducing infrequent information in a kinked adjustment‐cost model. We first show that optimal individual decision rules are both state and time dependent. We then develop an aggregation framework to study the macroeconomic implications of such optimal individual decision rules. In our model, a vast number of agents act together, and more so when uncertainty is large. The average effect of an aggregate shock is inversely related to its size and to aggregate uncertainty. These results contrast with those obtained with full information adjustment cost models. JEL Classification: E0,E1,E2,E3 Les effets macroéconomiques de l'information infréquente quand il y a des coûts d'ajustement. Les auteurs étendent la portée de la littérature spécialisée sur les règles de type Ss en proposant des postulats d'information infréquente et de fonction de coûts d'ajustement pliée. On montre que les règles de décision optimales des individus dépendent à la fois de l'état de l'environnement et du moment. On développe alors un cadre d'agrégation pour étudier les impacts macroéconomiques de ces règles optimales de décision. Dans ce modèle, un grand nombre d'agents agissent de concert, et optimales ce d'autant plus que l'incertitude s'accroît. L'effet moyen d'un choc au niveau global est inversement reliéà son importance et au niveau d'incertitude agrégée. Ces résultats contredisent ceux qu'on obtient dans des modèles de coûts d'ajustement avec pleine information.
