Les effets prix de l'offre foncière

Does land use zoning policy increases land prices by reducing developable land supply? To answer this question, we propose an evaluation of the relationship between land supply and land prices in the French region Provence-Alpes-Côte-d?Azur. The developable land supply is identified through geomatics analyzes using new generation of spatial land use micro-data (digitalized cadastral map, land and owner characteristics, land use zoning policies). We use two alternative econometric evaluation methods to estimate the price effects of land supply : spatial hedonic model and quasi-natural experiments. We show that with both methodologies the estimated relationship is positive, Municipalities with higher corrected developable land supply exhibit higher land prices. The disequilibrium between supply and demand for developable land is so high in Provence-Alpes-Côte d?Azur that municipalities that increase the supply of land through new developable zones (without coordination with neighboring municipalities) face an increase of land prices.
