The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...

In contrast to what several papers have argued recently, we show that firm heterogeneity fosters agglomeration of economic activity. If firms are more similar with respect to their total factor productivity, each company faces a lower propensity to export. This renders the home market more...

A major characteristic of the economic development in European and North America during the past 10-15 years is a fast expansion of the producer-service sector. This paper considers the location dynamics of two categories of firms: contact-intensive producer-service suppliers and other firms,...

This article aims at evaluating the link between knowledge properties and geographical proximity in the coordination R&D activities of firms. This evaluation is based on a statistical analysis of 614 responses to a survey carried out in France over 3740 plants having R&D activities. The concepts...

As we focus on the evolution of the relative weight of the Tunis area and the tunisian coastline in the industrial potential of this country, we would like now to complete the strictly economic analysis of the agglomeration and industrial location by an approach of the economy decision-makers as...

Economic geography and the new urban theories create an original analytical framework in spatial economics in order to study location issues within an environment of increasing returns and imperfect competition. Two research topics are related : the first one wonders when a symmetric...

This study analyses the relation between education and commuting behaviour of Dutch workers. Results show that, ceteris paribus, higher educated workers commute further, both in terms of distance and time. In addition, higher educated workers are more frequent users of public transport and of...

El artículo es una síntesis histórica y bibliográfica de la conformación de los centros urbanos y de mercado en Colombia, en un intento por obtener explicaciones teóricas de estos hechos relacionados. Sin embargo, no es fácil encontrar ese soporte desde la perspectiva de los modelos de...

This work aims to study the Portuguese regional agglomeration process, using the linear form the New Economic Geography models that emphasize the importance of spatial factors (distance, costs of transport and communication) in explaining of the concentration of economic activity in certain...

This paper presents a New Economic Geography model of structural change, agglomeration and growth. By assuming the same non-homothetic preference structure as Murata (2008), we obtain similar results in that a progressive reduction of trade costs allows the economy to pass from a...
