Informational interactions and the future of cities
1998
Present-day city growth is chiefly the result of new tertiary activities such as financial and producer services, R&D, or business administration. It seems that these activities need to be more spatially concentrated than traditional manufacturing activities. These new trends affect both the structure of cities and the structure of city systems. The specific nature of the new activities concentrated in city centers makes them information intensive. These activities consume human capital, knowledge and hightech capital, which are all rapidly changing inputs; they are based on complex decisionmakingprocesses; this renders them highly information-dependent. Inasmuch as these activities are the…
Externalités d'informations et évolution des villes
1999
Present-day city growth is chiefly the result of new tertiary activities such as financial and producer services, R&D, or business administration. These activities consume human capital, knowledge and high-tech capital, which are all rapidly changing inputs; they are based on complex decision-making processes; this renders them highly information-dependent. Inasmuch as these activities are the main key to understanding the city, information must play a leading role in understanding urban forms. The concentration of these activities in cities appears paradoxical in the era of information. They are agglomerated because of their need of proximity for exchanging information. But information can…
Neighbourhoods and the formation of towns : the role of information externalities
1997
The objective of this paper is to explain the role of information and of the progress made in information treatment and its transmission in the way that urban space evolves, and particularly its center-periphery structure. Information plays a more and more important role in production and innovation processes. Despite the very rapid progress in long distance information exchange possibilities, men and economic activities still demand proximity, in the form of direct, face-to-face contact. Today, the need for information exchange is one of the main sources of production agglomeration. What kind of information does it concern ? What sort of economic activities require proximity and how is tha…

Les schémas de concentration sectorielle au sein de l'Union Européenne : l'Est miroir de l'Ouest ?
2009
International audience; Cet article analyse l’évolution de la concentration sectorielle européenne à partir de deux échantillons derégions, celles de l’UE-15 sur 1980-2004 et celles des PECO sur 1990-2004. L’indice d’entropie utilisé parBrülhart et Traeger (2005) est calculé pour les secteursagricole, manufacturier et de services. La significativitéstatistique des écarts entre des sous-périodes est évaluée avec une procédure de type block-bootstrap.Nos résultats montrent une évolution des schémas de concentration sectorielle dans l’UE-15 et dans lesPECO, corroborant les enseignements des modèles d’économie géographique: la baisse des coûts detransaction modifie les schémas de concentration …
Urban Segregation and Unemployment: A Case Study of Marseille (France)
2015
International audience; In this paper, we study the effects the Marseille’s spatial organization on unemployment. More specifically, differences in characteristics of residential population induce urban stratification so that the urban structure could affect the propensity of unemployment. This potential link is called the reverse causality. In order to evaluate the effect s of spatial structure on unemployment, we implement a spatial probit model to reveal the employment probabilities of young adults still living with their parents. In a first step, we highlight the realness of residential segregation in Marseille by a topology of neighborhoods by degree of deprivation with a principal com…

Interactions, spillovers de connaissance et croissance des villes européennes. Faut-il préférer la géographie, le climat institutionnel ou les réseau…
2013
Knowledge spillovers within urban economies are also sources of spillovers between cities. We examine how knowledge spillovers influenced the economic growth of 82 European metropolises over the 1990-2005 period. We model knowledge spillovers between cities on the basis of five specific interaction patterns based on geography, networks of multinational firms in advanced services, institutional climate and two combinations of these factors. Spatial models are estimated to detail the effects of growth factors in terms of spillovers and externalities. We show that spillovers are local rather than global and that interactions among cities accelerate the convergence process based on gross value …
