Vertically linked industries and the monocentric city (Download)
In this paper I study how the relations between the industry and more and more specialized services firms can explain the rise of suburban industrial clusters. I build an urban economics model with two vertically linked sectors. The vertical disintegration liberates the location choice of the industry and the services. Then, the industry clusters that need more land may leave the center (what characterizes the modern city). When the industry is higherly linked to the services it agglomerates around the CBD (what characterizes the post-modern city).

Why is central Paris losing jobs (Download) - the latest version is only available in french (Chapitre 8 de la thèse)
Brueckner et alii (1999) have explained urban population pattern through amenities distribution. Based on their model, this paper introduces a productive sector and helps understand employment suburbanization in a new way. Considering how amenities are valued, the 'people follow jobs' vs 'jobs follow people' case is discussed for CBD and hogh-brawn services firms. If they favour natural amenities, they might leave the historical center. A big constraint against that move is that the firm wants to keep its employees who may all live around the center. Despite conventionnal centripetal forces, they can settle in the suburbs before the households. People may than follow the firm in the suburbs.

Employment spread and commuting in the Greater Paris Area (Download)
Over the pas three decades, the Greater Paris Area has been a fast growing metropolitan area and has experienced important advances in its economic and geographic organization. Mostly three changes are to be mentioned. First it moved from an industrial economy to one of the most services oriented in the world (81% of its jobs). Secondly, suburbanisation has been increasing and the metropolitan area is becoming wider and wider. Some edge cities are now more than 80km away from Notre-Dame. Thirdly, the organization of the area has changed as well. The jobs that used to be concentrated mostly in Paris have left for the suburbs and secondary employment center have grown fast. A few SEC have arisen in the immediate vicinity of Paris (La Defense is now the most important CBD in Europe), others in what was once a rich agricultural land (Roissy Airport) or an Impressionnist landscape (Vallée de la Seine and Vallée de l'Oise).
That third phenomenon is the focus of the present paper. As far as employment is concerned, the main question addressed is the consequence of this spread on commuting. Greater Paris has changed. Its economy has changed. The locations and types of jobs have done so, as shown in the first sections.
But when a city such as Paris spreads, the commuting pattern evolves. This paper also shows that in the greater Paris area, employment suburbanization, both clustered and spread, has lead to an increase in the commuting distances in the remote suburbs but to a decrease of the commuting distance in the mid distant suburbs. It also shows different organisations of the employment areas in the eastern and the western part of the urban area.

Is Central Paris still that rich? (Download)
From 1975 to 1999, employment in Paris metropolitan area has become more and more decentralized. This deconcentration is almost half spread and half clustered.
Parallel to the sprawl of jobs, the growth of a services oriented economy has led to an increase in sectoral concentration. But there are no clear evidences of a vertical spatial desintegration, because by the same time the places tend to diversify. An explanation might be that the sprawl relies both on endogenous job creations and on job relocations: the relocations tend to increase the specialisation of the clusters but endogenous growth is more diverse and residential.

Astigmate Statistics and the Evolution of the Economic Geography of Greater Paris in European Journal of Geography, 324 (2005) (Abstract, Text)
The economic geography of greater Paris has experienced important changes in the last 25 years. The increase in both services and high-tech jobs has obviously had consequences on the employment location. Such changes might affect the way data and statistics help to understand the region. They might not be as accurate in the end of the period as they were at the beginning. Hence the data that were available between 1975 and 1990 seemed to reveal a dramatic evolution for the eastern part of the urban area. A new analysis made on the same data but coded in a different way (thanks to a new nomenclature) tends to tell another story. Both eastern and western parts have evolved, but the former data were able to reveal only a part of the changes. And that part concerned mostly the jobs concentrated in the western part. So it missed the changes of the east.

Regional Integration The case of Greater Paris in European Journal of Geography, 305 (04-2005) (Abstract, Text) - an english version will be available soon)
The Greater Paris area has a direct influence over its administrative boundaries. The commuting pattern shows people crossing the entire Parisian Basin. The industrial pattern shows a vast and complex organisation made of functional and sectoral complementarities : companies are spread over the basin, places are specialized, activites are concentrated,…
Of course, each area has very particular relations with Paris. But some of the most dynamic areas take an active part in the globalisation of the economy and do that on their own. Hence the Parisian basin is less and less hierarchical. Peripheral region take advantage of their proximity to Paris to attract Global Firms and to develop activities that are not dynamic in Paris.

Whatever the society, the huge densities of people and activities in the cities give some purely urban characteristics to such concentrations. Therefore, the development of urban studies in almost all the social sciences is not a surprise. We focus on the way geographers and economists manage this situation. It is striking that microeconomists consider city more as a space than something within the space. An explanation can be sought in the way theoretical space is built: whereas an economist seeks an equilibrium, a geographer (as a space analyst) is more preoccupied by the way places interact. An economic analysis of places depicts the set of activities without taking care of the places. In a Geographical one there is somehow a quality of the place that creates something new. Considering this, economists’ job ends when all the places are built, that is to say when geographer’s one begins. Indeed, space analysis seems to host both the holist and the individualist conception of Society.

In a region changing as fast as Greater Paris, particularly the edge of the metropolitan area, the figures from the last census may answer some interesting questions. Is the conurbation expanding? Is the city evolving towards a monocentric or a polycentric configuration? We look at commuting in the whole Parisian basin in order to understand how the huge metropolitan area interacts with its immediate surrounding area and with the other cities in the basin. The past decade has seen an amplification of a trend that emerged in the early 1980s: the city continues to spread, but it is now extending to larger urban centres. There seems to be a reorganisation of the edge of the metropolitan area around these secondary centres, which is producing two kinds of fringe. The first, the closest to Paris, has simply become part of the metropolitan area. Most of its residents and workers now live and work in the urban area and a hierarchy is emerging between these centres. The second is not yet part of the metropolitan area, even if many of its residents are commuting to the city. This pattern is common around Paris. It is observed in almost all the large cities of the basin. The regional metropolitan centres attract and shape the region they belong to, while developing increasing links with Paris. Since there are few cross-links between the different regions of the Parisian basin, it still has a monocentric configuration: Paris interacts with all the main cities of the regions surrounding the capital region, while these cities shape their local areas.
