These are 10 of my favourite #UrbanEconomics articles published in 2020, in alphabetical order by author, continuing with a tradition from the last couple of years

1) @TrebAllen, Arkolakis & Takahashi, JPE. Shows key theoretical properties & predictions of large class of trade/geography gravity models depend on 2 parameters: elasticities of supply and demand. Proposes IV estimation strategy relying on GE structure https://t.co/5On1AQkbeP
2) Ambrus, Field & @rmgonzalez046, AER. 1854 London: prices fell in blocks served by well transmitting cholera. Differences persist. Model: tenants change as contracts expire, -ve externality of poor tenants, shock makes landlords persistently target poor https://t.co/6uaxjG6Bmf
3) @kon_buechel & @maxvehrlich, JUE. More sociable individuals sort into cities. Even after accounting for sorting, those in denser areas call each other more often & longer, suggesting complementarity between face-to-face and phone interactions https://t.co/bymmL4PzaJ
4) @CarozziFelipe, JEEA. Shows how credit constraints affect composition of housing sales & access to home-ownership by the young. Neat model of housing markets as ladders with young in cheap units, possibly trading up as they age, post-2008 UK evidence https://t.co/PCn7w35Qu8
5) Harari, AER. City shape matters. More compact (circular) Indian cities grow faster (IVs compactness with mechanical expansion + geographic constraints). Compactness affects road network, location patterns, quality of life. Regulations affect shape https://t.co/TbXX9X4qwC
6) Heblich, @ReddingEcon & Sturm, QJE. Uses quantitative urban model & spatially disaggregated data for London 1801-1921 to explore how steam railways triggered workplace-residence separation, enabling substantial agglomeration in production & residence https://t.co/Z0CnPlQnMY
7) Liu, Rosenthal & Strange, RSUE. Agglomeration in tall buildings depends on street access, height amenities & productivity. Ground & high floors most valuable. Density & law firm sales indicate strong same-floor spillovers quickly attenuating vertically https://t.co/YxXFQ4yydZ
8) @OtoPeralias, JDE. Explores origins of settlement patterns exploiting spatial discontinuity in insecurity in medieval Spain. Frontier warfare encourages population concentration in few livestock-oriented (vs. agriculture) settlements, strong persistence https://t.co/FkXwJ9EohA
9) Owens, @HansbergRossi & Sarte, AEJEcPol. Rationalises healthy Detroit CBD surrounded by vacant land through model with residential externalities leading to coordination problem, evaluates development guarantees & other alternatives https://t.co/WMQiUhWf46
10) @piazzesi, Schneider & @stroebel_econ, AER. Housing search model with many segments, agents with different search ranges, broad searchers that narrow down by segment inventory. Helps think about Beveridge curve, scope & connectedness in housing markets https://t.co/wmpnDqsoL1

Long rant: This @WSJ article bemoaning the decline of price theory is really worth highlighting. The economic theories and so called "laws of economics" that the WSJ consistently and religiously defends, are the source of their authority, power and privilege.


So called economic "theories" like "you get paid exactly what you are worth" and "markets are perfectly efficient" and "when wages rise, jobs fall" and "raising taxes on the rich kills jobs and growth" and "increasing justice decreases economic efficiency" and...

"Government intervention in markets always creates more harm than good" and "any regulation that constrains corporations kills growth and productivity", etc etc are effectively a protection racket for the rich. It is a set of internally consistent and mathematized conjectures...

That are all demonstrably nonsense. But getting people to accept these "theories" as laws of nature and immutable, timeless truths is the most effective way our current economic elites have found to maintain and enhance the status of the powerful and persuade the weak and poor...

to shut the fuck up and accept their lot in life. Now, FINALLY, some economists- are actually beginning to look at the real world evidence to determine whether these propositions actually describe anything real here on planet earth. Let me save you some time. The answer is NO.
