Resilience in a noisy urban system

open access: yesRegional Science Policy &Practice, EarlyView., 2023
Abstract The ability of cities to recuperate from disturbances and return to their evolutionary pathways depends, first and foremost, on the type of damage that the shock created. But in addition, it depends on how information is transmitted in the urban system and on how noise filters distort the information that reaches economic agents.
