The impact of information improvement on stability will be examined for continuous dynamics. It is conventionally believed that removal of uncertainty always brings additional stability to an existing equilibrium. 133 This research however shows that a relationship between information and equilibrium stability may not be monotonic. Indeed removal of information lag may sometimes destabilize the otherwise stable continuous model. Focusing on two-dimensional continuous dynamics, the paper explores the stability condition in theory and numerically, the conclusion drawn on which can be generalized to multiple-dimensional system.
