Does regional income divergence drive up national housing prices and rents?
Core argument: From 2000 to 2018, median household incomes rose about 15% more in cities already in the top 10% than in cities initially in the bottom half, while the FHFA house price index rose 31 percentage points more than the overall CPI.
From 2000 to 2018, median household incomes increased by about 15% more in cities that were already in the top 10% as compared to cities that were initially in the bottom half. [Over the same period] the FHFA house price index rose by 31 ppt more than the overall CPI. This housing price increase is unevenly distributed and driven in large part by the higher rate of housing price increases in major cities. Relative to CPI, house prices rose by 49 percentage points in New York, 96 percentage points in Seattle, 129 percentage points in Los Angeles, and 113 percentage points in Miami. To understand the link between regional inequality and average housing prices, we note that if a location experiences relatively higher productivity growth, then the associated rise in income will increase demand to migrate there. If there is a mismatch between the places where people increasingly want to live and places with the space and zoning policies to absorb population, then housing costs can increase a lot in the in-demand cities, while decreasing only a little elsewhere.
