Les 30 dernières années ont montré le développement d'un nouveau type de développement urbain en France, appelé périurbanisation. Une ceinture périurbaine est située hors d'une ville et elle est occupée à la fois par des ménages et par des agriculteurs. Les auteurs proposent un...

This paper presents a microeconomic model of residential location that explores the emergence of a mixed belt where residents and farmers coexist beyond a city. The model is based on integrating urban economics with cellular automata in order to simulate equilibrium patterns in 2D and through...

Comment expliquer l'existence de poches de chômage élevé au sein des villes ? La théorie économique identifie deux explications concurrentes : les effets néfastes sur le marché du travail associés à la ségrégation résidentielle, et l'éloignement de ces zones aux lieux d'emplois. Le...

There is a wide consensus among international institutions and national governments in favor of compact (i.e. densely populated) cities as a way to improve the ecological performance of the transport system. Indeed, when both the intercity and intra-urban distributions of activities are given, a...

We present a two-country four-region model of new economic geography that partly endogenizes the level of trade costs. Contrary to the existing literature, we assume that international unit shipping costs depend on the volume of trade, due to the presence of density (dis)economies. We show that...

The objective of this paper is to apply different welfare approaches to the canonical model developed by Krugman, with the aim of comparing the only two possible market outcomes, i.e. agglomeration and dispersion. More precisely, we use the potential Pareto improvement criteria, as well as the...

Although transport costs are a key-ingredient of New Economic Geography, the transport sector is usually abstracted away from the analysis. Put differently, freight rates are taken as parametric and are not set by the market. This paper studies the relationships between transport costs, industry...

We study the impacts of changes in international trade and domestic transport costs on the internal geography of countries in the presence of geographical asymmetries.

We study the impact of falling international trade costs and falling national transport costs on the economic geography of countries involved in an integration process. Each country is formed by two regions between which labor is mobile, whereas there is no international mobility. Goods can be...
