We review the theoretical links between growth and agglomeration. Growth, in the form of innovation, can be at the origin of catastrophic spatial agglomeration in a cumulative process à la Myrdal. One of the surprising features of the Krugman (1991) model, was that the introduction of partial...

This paper examines empirical strategies that have been or could be used to evaluate the importance of agglomeration and trade models. This theoretical approach, widely known as ‘New Economic Geography’ (NEG), emphasizes the interaction between transport costs and firm-level scale economies...

This paper analyzes empirically the effect of spatial agglomeration of activities on the productivity of firms using French individual firm data from 1996 to 2004. This allows us to control for endogeneity biases that the estimation of agglomeration economies typically encounters. French firms...

Using data on name distributions in 95 French departments observed from 1946 to 2002, we investigate spatial and social mechanisms behind the transmission of parental preferences. Drawing inspiration from recent work on social interactions, we develop a simple discrete choice model that predicts...

Clusters have already been extensively shown to favor firm-level economic performance (productivity, exports, innovation etc.). However, little is known about the capacity of firms in clusters to resist economic shocks. In this paper, we analyze whether firms that agglomerate in clusters and...

This paper analyzes empirically a public policy promoting industrial clusters in France. Cluster policies have become popular in many countries but have not been extensively evaluated empirically. We use data on production and employment for firms that benefited from the policy and on firms that...
