Scott Alexander argues that increasing housing density in a city may actually increase local prices due to induced demand, while lowering prices nationally. Longer summary

Scott Alexander challenges Matt Yglesias's claim that building more houses lowers local house prices. He argues that while this may be true on a marginal level, looking at the extremes shows a different picture. The densest US cities (New York, San Francisco) are also the most expensive, while the least dense areas have the lowest prices. Scott proposes that increasing density in a city like Oakland would likely increase its prices due to induced demand, as it becomes more attractive to people seeking big city amenities. He suggests that building more houses would lower prices nationwide, but not necessarily in the specific city where construction occurs, creating a coordination problem for housing policy.

Scott Alexander presents counterarguments to YIMBY housing policies, questioning their effectiveness and considering NIMBY perspectives. Longer summary

Scott Alexander steelmans the NIMBY (Not In My Back Yard) position against YIMBYism (Yes In My Back Yard) in housing policy debates, particularly focused on San Francisco. He argues that: 1) San Francisco's housing growth rate is not uniquely low, 2) Building more housing may not significantly lower rents, 3) Increased housing supply could potentially increase rents due to agglomeration effects, 4) NIMBYs have valid reasons to oppose development, and 5) Increasing housing supply might trap more people in an undesirable equilibrium. He concludes by acknowledging the lack of clear alternatives but expressing skepticism that simply building more housing will solve the problem. Shorter summary
