Cahier 2015-27| Title: | Zipf’s law, Gibrat’s law and Cointegration | | Abstract: | This paper examines the methods to detect the nature of the urban growth processes. It seems that cointegration testing enables to disentangle two versions of Gibrat’s law: a first one with growth shocks that are iid across time and cities (implying convergence of the city-size distribution towards Zipf’s law), and an alternative one with growth shocks that are only iid over time (implying conservation of the initial structure of the city size distribution). | | Keyword(s): | Zipf’s law, Gibrat’s law, Cointegration tests, unit root tests, urban growth, urban system | | Auteur(s) : | Aurélie LALANNE, Martin ZUMPE | | JEL Class.: | R00, R11, C41, O40 | Télécharger le cahier Retour à la liste des Cahier du GRETHA (2015) |
