EMERGENCE OF LEAPFROGGING FROM RESIDENTIAL CHOICE WITH ENDOGENOUS GREEN SPACE: ANALYTICAL RESULTS

Leapfrog development is a typical form of sprawl. This paper aims at analyzing the existence, size, and persistence of leapfrogging in a dynamic urban economic model with endogenous green amenities. We analyze whether incoming households choose to settle at the fringe of the city or to jump further away depending on their preferences and the structure of the city. We first provide an analytical treatment of the conditions and characteristics under which a first leapfrog occurs and show how the optimal choice is affected by the size of the city, income, commuting costs, as well as the size of the area where green amenities are considered. We then study how further leapfrogging and multiple urban rings may appear and be maintained in the long‐run equilibrium, and how infill processes take place through time.     

EXPLORING THE DETAILED LOCATION PATTERNS OF U.K. MANUFACTURING INDUSTRIES USING MICROGEOGRAPHIC DATA*

ABSTRACT We use a point‐pattern methodology to explore the detailed location patterns of U.K. manufacturing industries. In particular, we consider the location of entrants and exiters versus continuing establishments, domestic‐ versus foreign‐owned, large versus small, and affiliated versus independent. We also examine colocalization between vertically‐linked industries. Our analysis provides a set of new stylized facts and confirmation for others.     

Reflections on the Identities and Roles of the Artists in European Paleolithic Societies

In an attempt to introduce concerns with social identities into the discussion and understanding of the making of what we call Paleolithic art, this article considers issues of gender, skill, apprenticeship, and tradition. We note that, as in every period of history, Paleolithic art can be seen as embedded in the society that studies it. Over the last 20 years, the research attention given to women in Paleolithic societies has grown considerably, leading us to ask what could have been the roles of women in Paleolithic art. On what criteria could we base a determination of those roles or of other social identities that were likely part of the making and viewing of Paleolithic art?Thanks to our microscopic analysis of engravings, it is possible to identify the skill level and expertise of the artists and thus to address the question of apprenticeship and how these techniques were transmitted. We observe many similarities that allow us to group together various works of art, sometimes from very distant sites, which indicate a movement of ideas, objects, and people. Are we talking about “imitation”? How can we define an “invention” within a social context strongly bound by traditions?     

Labor Specialization, Transport Costs, and City Size

This paper proposes a simple model of pre-industrial urbanization. Agglomeration stems from increasing returns generated by the specialization of labor, whereas dispersion is provoked by the transport costs of the agricultural good. Considering the existence of some urban institutions (in particular guilds), the equilibrium size of cities is derived and it is efficient. Within this framework, the effects of urban domination (e.g., taxation of agriculture) and the emergence of primate cities are explored. Finally, the transition between early and modern urbanization is studied.     

La représentation de l’espace public par la photographie : Une étude de cas dans la région de Montréal (Québec,Canada)

Beyond the material forms that constitute public space, it is subject to representations or images that shape the types of use, forms of appropriation, and general perception that people have of it. Following a centre‐periphery gradient that allows us to compare three zones of the Montreal region (pericentral, periurban, and the northern ring), we analyzed photographs available within cyberspace (from different municipalities and boroughs, local newspapers, and social media) to draw out representations of public space. What can photographs available online tell us about how space is perceived? We have established a typology of images of public space (idyllic nature, urban scene, festive space, empty space, family portrait) that are representative of the overall corpus studied. We have compared these results with a correspondence analysis to clarify the structure of interaction between the variables. The analysis demonstrates that the representations are more differentiated between neighbourhoods than between regions, and that while newspapers and municipalities represent more themes of sociability and family life, social media shows more empty spaces, whether they be monumental spaces, or spaces of daily life.
