Key Takeaways
Full Summary
Housing affordability in the U.S. has deteriorated, with average home prices increasing by 60% from 2019 to 2025, as reported by the Harvard Joint Center for Housing Studies. Research conducted by Caitlin Gorback at the McCombs School of Business identifies foreign investment as a key driver of rising housing costs, especially in regions with significant foreign buyer activity.
The study reveals that from 2009 to 2018, the elasticity of housing supply—how quickly builders respond to price increases—was notably low, with only a 0.26% increase in supply for every 1% rise in prices. This contrasts sharply with the responsiveness seen before 2000.
Gorback emphasizes that the dynamics of housing supply in U.S. cities have shifted significantly over the past two decades, leading to insufficient new construction to meet demand. These findings suggest that foreign investment and regulatory environments are critical factors influencing housing affordability.
