The main aim of this study is to evaluate the nature and the dynamics of agglomeration forces inside specific network structures like industrial districts. Firms seem to be attracted in these locations by the opportunity of exploiting the advantages of an inter-firm coordinating structure. This...

In this paper, we analyse the geographic concentration of economic activities within the framework of a two countries and four regions model. Trade both between regions and countries entails transport costs which are differentiated according to the interregional or international nature of the...

L'analyse contenue dans cet article envisage une chaîne publique et une chaîne privée en monopole comme deux hypothèses alternatives concernant la structure du marché télévisuel. Nous comparons les tarifs et les valeurs publicitaires émergeants de ces hypothèses alternatives en...

In this paper we propose an example of successive oligopolies where the downstream firms share the same decreasing returns technology of the Cobb-Douglas type. We stress the differences between the conclusions obtained under this assumption and those resulting from the traditional example...

This paper analyses successive markets where the intra-market linkage depends on the technology used to produce the final output. We investigate entry of new firms, when entry obtains by expanding the economy as well as collusive agreements between firms. We highlight the differentiated effects...

In this paper we analyze how the technology used by downstream firms can influence input and output market prices. We show via an example that both these prices increase under a decreasing returns technology while the countrary holds when the technology is constant.
