"Increased supply always leads to lower prices" Not in real estate economics. Housing isn't a commodity market. There are firm price tiers, different methods of construction, different fixed costs for those methods, and drastically different markets for individual neighborhoods. Real estate isn't fungible and it's isn't particularly liquid. Basically none of the requirements of Econ-101-style supply and demand are me…
> Not in real estate economics. Increased supply leading to higher prices would be something that Economist would crawl over each other to study, if true. So where are these studies? Who are the professional economists who support this view?

"None of this dismisses the fact that displacement from specific homes happens when low-income housing is literally knocked down to build high-end towers. A good amount of new supply in cities, though, can rise on under-utilized land (former industrial plots, surface parking lots, abandoned properties, etc.). And the cumulative effect of all that new supply can hold down rents across neighborhoods and cities, including for the poor."
Nobody thinks that new housing is bad - in the long term. Where economists start to disagree is how to prioritize low-income housing and market-rate construction in the near-term:

"To be sure, more supply is needed, but unless it is targeted to those who need it most, it will only help wealthier residents."
"'Filtering,' where older housing units trickle down to lower-income families as they age, can happen in the broader metropolitan context. But it can take decades for filtering do deliver truly affordable units to lower-income households. As apartments age, the rent of a typical unit – not in a hot area - declines an average of 0.31 percent per year so even after 30 years, the rent will have fallen by only 9 percent."
"In gentrifying neighborhoods, filtering does not work at all, because land values and rents rise as the neighborhoods become more desirable and developers bid up land values. So lower-income households must look in other neighborhoods where services and schools are likely to be much weaker. Hence the gentrification process can reconstruct economic segregation."
