[fre] La nouvelle économie géographique : agglomération et dispersion par Gilles Duranton . À la croisée des chemins du commerce international, de l'économie urbaine et de la micro-économie spatiale, la nouvelle économie géographique cherche à s'imposer comme un champ d'analyse...

This paper uses a unique labour force survey to document workplace communication patterns in urban, suburban and rural areas. A number of interesting stylised facts are distilled relating to workplace communication: its intensity, within-firm communication, communication external to the firm and...

Using the idea that the division of labor is limited not only by the extent of the market but also by its heterogeneity, it is proposed in this paper that ''globalisation'' is redrawing the lines of division within and between countries. Our model builds on the concept of productive systems. Our...

Large cities produce more output per capita than small cities. This higher productivity may occur because more talented individuals sort into large cities, because large cities select more productive entrepreneurs and firms, or because of agglomeration economies. We develop a model of systems of...

This paper reviews recent empirical research on the growth of US cities. Several key drivers of urban growth have been identified: roads, amenities, human capital, entrepreneurship and agglomeration effects, housing supply constraints, and industry shocks. The implications of these findings for...

We consider the literatures on urban systems and New Economic Geography to examine questions concerning agglomeration and how areas respond to shocks to the economic environment. We first propose a diagrammatic framework to compare the two approaches. We then use this framework to study a number...

We estimate the effect of interstate highways on the level and composition of trade for US cities. Highways within cities have a large effect on the weight of city exports with an elasticity of approximately 0.5. We find little effect of highways on the total value of exports. Consistent with...
