Build, Baby, Build : The Science and Ethics of Housing Regulation (2024) written by Bryan Caplan and illustrated by Ady Branzei is a marvelous comic book introduction to the Yes In My Back Yard (YIMBY) movement and the economic ideas behind it. Caplan is an economist at George Mason University.
The book starts with the economic fundamentals of supply and demand and why houses cost a different amount in different places. Then Caplan explains how scarcity is created by rules that don’t allow for the full potential economic use of land. Here the Glaeser and Gyorko paper on the impact of zoning is introduced. Nicely, Caplan introduces in comic form the actual authors. This method is continued throughout the book and some surprising characters appear. Caplan then describes how reducing restrictions can help. The objections to zoning changes are next to be addressed. The French economist Bastiat is introduced and his concept of missing possibilities is very well added. After touring more economists freeing up zoning is described as a ‘consilience’, that is position that can be reached from different starting points and values. Finally the YIMBY path is outlined and the way it can be realised is described.
YIMBYism has a pretty strong base and is fairly popular across different political views. Caplan does really well putting the argument into comic form and Branzei’s illustration’s are excellent. For housing wonks the book references many of the major economic writers on the subject and there is an extensive notes section. It’s hard not to be delighted when someone like ‘Bernard Siegan’ is mentioned and brought to life. It’s really a very well done book. It’s surprising just how well a comic can be used to introduce so many ideas. It’s also fun how so many figures from economics and philosophy are brought to life.
Build, Baby, Build is a fantastic book that a lot of people will enjoy and get a lot out of. It’s a tremendous use of comic books and a good short read to understand why so many people support zoning deregulation. After reading it Nolan Gray’s also excellent ‘Arbitrary Lines’ would make a very good follow on.
