Query: Is the monocentric urban economic model still empirically relevant?
  Assessing urban econometric predictions in 192 cities on five continents   Despite a large body of work that developed over more than 60 years, and
numerous applications in theoretical papers, the empirical knowledge
accumulated on the monocentric urban model and its extensions remains limited.
Using a unique dataset gathering spatially explicit data on rents, population
densities, housing sizes, and transport times in neighborhoods inside 192
cities on all continents, we investigate on a systematic basis the empirical
relevance of the key stylized facts predicted by this model. Some of these
predictions appear extremely robust: cities are more spread out when they are
richer, more populated, and when transportation or agricultural land is less
costly, and 95\% of the cities of our sample exhibit the predicted negative
density gradient from the city center to suburbs. Rent variations inside cities
are also significantly explained by transport times in most of the cities (159
cities). However, housing production (and population densities) seem
significantly impacted by rents in only slightly more than half of the cities
(106 cities). Nevertheless, high levels of informality, strong regulations and
planning, specific amenities (e.g. coastal amenities) are, as expected by the
theory, main factors leading to the discrepancies. Overall, several decades
after its creation, the standard urban model seems to still capture
surprisingly well the inner structure of many cities across the world, both in
developed and in developing countries.
