Agglomeration, Transport and Productivity: Evidence from Toulouse Metropolitan Area

Abstract:

Economic activity tends to be highly concentrated. These agglomeration or concentration forces are driven by spatial externalities on productivity, and are named agglomeration externalities. Transport improvements – by reducing the interaction cost between economic agents placed in different locations – can extend the geographic scope of these externalities on productivity. Furthermore, transport exposure may also affect productivity directly by making some places more attractive than others which brings firms’ and employees’ relocations. Therefore, the objective of this paper is twofold. Firstly, to estimate the extent of agglomeration externalities at a very fine urban scale, and secondly, to estimate the – direct and indirect – impact of transport exposure, measured by two continuous indexes of accessibility, on productivity, using very disaggregated and georeferenced data on more than one million employees working in a typical European city in 2013 and 2015.

This is joint work with Emile Quinet and Celia Ruiz Mejia.

The presentation will be given in French.
