The influence of the diffusion of information and communication technologies (ICT) on the organisation and location of firms has been the subject of an important debate in economic literature. In contrast we focus in this paper on the effects of the organisational and spatial structures and...

Cet article est dédié à l'analyse des facteurs qui influencent l'usage des Technologies de l'Information et de la Communication TIC) par les firmes industrielles françaises et vise à identifier des sources d'inégalités dans ce processus. Nous testons l'influence de facteurs...

In this paper, we consider the factors influencing the adoption of Information and Communication Technologies (ict) by firms and intend to identify the sources of inequalities in this process. We test the influence of organizational and spatial factors on the intensity of ict use by French...

This paper investigates the relationship between the geography of firms and the intensity of use of information and communication technologies (ICTs). Our approach to the geography of firms is multifaceted, in relation to the various characteristics of their location area(s), to their...

In this paper, we present a model of 'collective innovation' built upon the network formation formalism. In our model, agents localized on a circle benefit from knowledge flows from other agents with whom they are directly or indirectly connected. They support costs for direct connections which...

The modelling of networks formation has recently became the object of an increasing interest in economics. One of the important issues raised in this literature is the one of networks efficiency. Nevertheless, for non trivial payoff functions, searching for efficient network structures turns out...

This article aims to analyse the factors that determine the existence of multi-unit firms and that influence the intensity of their organisational fragmentation. More precisely, we identify the firm’s internal characteristics and their spatial, sectoral and competitive environments that are...

This paper analyses the modalities according to which a large European university collaborates with firms by exploring its relational portfolio. We address this issue by exploiting a database listing more than 1000 firms having collaborated with the University Louis Pasteur between 1990 and...
