Abstract

Cet article présente les contributions théoriques et empiriques récentes à la littérature macroéconomique qui remettent en question l'hypothèse d'information parfaite. En prenant en compte les frictions informationnelles rencontrées par les agents économiques, il est possible d'expliquer certaines des régularités empiriques qui ne peuvent pas être expliquées par le cadre standard des anticipations rationnelles avec information parfaite. À titre d'exemple, nous montrons que l'estimation du signe, de l'ampleur et de la persistance des effets des politiques monétaires et budgétaires peuvent varier lorsque l'on prend en compte les frictions informationnelles auxquelles sont confrontés les acteurs économiques.
