This paper analyzes the effects of local externalities on the probability of starting a new economic activity. We use firm-level data and geographic information on French zip-codes for 1993-2002. Poisson and Negative Binomial panel data models are estimated as they naturally allow for large sets...

Firms are more productive on average in larger cities. Two main explanations have been offered: firm selection (larger cities toughen competition, allowing only the most productive to survive) and agglomeration economies (larger cities promote interactions that increase productivity), possibly...

Le but de cette Table Ronde est d'évaluer les effets économiques des grands projets d'infrastructures de transport. On parle de grands projets pour désigner les bonds qualitatifs, qu'il s'agisse de négocier le tracé d'anneaux autoroutiers ou ferroviaires venant recouper la dispersion des...

The purpose of this Round Table is to assess the economic effects of major transport infrastructure projects. The term "major projects" is used to designate qualitative leaps, be it the mapping out of new road or rail rings to link disparate radial penetration routes or the introduction of...
