Ths subject of this study is the rationale behind two, at first sight conflicting trends: on the one hand we see a strong growth in the numbers of mergers and acquisitions, and on the other there is much attention for the (perceived) growing importance of small and medium-sized enterprises...

This report presents the results of an EIM study about spin-off businesses. These are new, independent enterprises set up by departing employees with assistance of former employers. The study entails preliminary exploration of that phenomenon, including analyses of the characteristics of...

Overzicht van theoretische factoren die belangrijk zijn bij het verklaren van schaalgrootte van bedrijven en verschillen in schaalgrootte tussen vergelijkbare bedrijven. Naast de theoretische factoren worden enkele relevante trends beschreven en wordt gekeken naar de impact van deze trends op de...

This article estimates the welfare losses due to the congestion externality on the Paris Ring Road (PRR). Doing so, we illustrate the debates linked to the valuation of this ?non market interaction?. This work is made possible thanks to a rich dataset describing the PRR?s usage...

Cet article se propose de mettre en perspective les théories "traditionnelles" de la croissance régionale avec la théorie de l'entrepreneur. La revue de littérature que nous menons montre que, si la figure de l'entrepreneur n'est que très partiellement mobilisée dans les explications de la...

On the southern part of the Parisian Maréchaux' boulevards, the old bus line Petite Ceinture has been replaced by a modern tramway (T3). Simultaneously, the road-space has been narrowed by about a third. A survey conducted on 1,000 users of the T3 shows that the tramway hardly generated any...

This research focus on the congestion cost of the Parisian ring-road. We mobilize a speed-density relation which enables us to differentiate the costs of the road's use and its congestion according to speed-classes of 5 km/h. We lead this work at three analytical scales thanks to a large...
