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...

We study how density (dis)economies in interregional transportation influence location patterns in a standard new economic geography model. Density economies may well delay the occurrence of agglomeration when compared to the case without such economies, while agglomeration is both more likely...

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...

Although economic historians consider technical change as being a significant factor explaining the evolution of the spatial organization of an economy, economic geography still fails to address this important issue. By developing a simple two-region general equilibrium model under monopolistic...

Cet article étudie l’effet des prix de vingt-trois catégories d’aliments sur la distribution de l’indice de masse corporelle (IMC) de la population adulte française, à l’aide des données de scanner du panel de ménages TNS-WorldPanel. Les résultats de régressions quantiles...
