Geetika Nagpal and Sahil Gandhi study zoning deregulation in Mumbai, India. As I pointed out in my video, Skyscrapers and Slums: What’s Driving Mumbai’s Housing Crisis?, Mumbai has very restrictive floor area ratio regulations (also called Floor Space Index, FSI, regulations, see the video for an explanation) which means taller buildings require more unused land.

Geetika Nagpal and Sahil Gandhi study zoning deregulation in Mumbai, India. As I pointed out in my video, Skyscrapers and Slums: What’s Driving Mumbai’s Housing Crisis?, Mumbai has very restrictive floor area ratio regulations (also called Floor Space Index, FSI, regulations, see the video for an explanation) which means taller buildings require more unused land. In 2018, however, FAR was liberalized for some streets:
Mumbai’s stringent FAR limits, which are much lower than those of comparable megacities, are often criticized for causing housing unaffordability (Bertaud, 2004). Despite the criticism, establishing a causal effect has been challenging because of a lack of changes in FAR regulations. The relaxation in 2018 linked a parcel’s FAR to the width of its bordering road, providing incremental FAR relaxation for parcels on roads wider than 12 meters. Parcels on narrower roads remained ineligible for the relaxation. Our reduced-form specification uses a DID design to compare developments built between 2014 and 2022 on wider roads with FAR relaxation with those on narrower roads that remained ineligible.
…The FAR relaxation results in a significant supply response, driven by less expensive, smaller housing units. Developers fully utilize the FAR relaxation, increasing the average
number of apartments in each treated multifamily development by 28% relative to the control.
…We develop a structural model of housing supply and demand that incorporates the provision of amenity floorspace and shows that average home buyer incomes are 3.18% lower post-relaxation.
