ABSTRACT
Within urban areas, full ownership of land and property has decreased, to be replaced to a large extent by copropriété. The legal status of co-ownership then encompasses the surrounding land, which becomes the common parts of the co-owned property. The increased flexibility of zoning has progressively modified the structure of demand and supply by increasing the demand for agricultural land located in peripheral areas of major cities from non-agricultural users that anticipate re-zoning. Differences exist in the evolution of prices because of spatial reasons and because of the structure of each sector. The considerable and general increase in land prices is linked with the evolution of the office market. Active speculators are looking for windfall gains on land, and take into account any relevant information that will allow them to purchase or sell at the right moment.
