Why do investors undervalue housing despite superior risk-adjusted returns?
Core argument: Housing returns matched equity returns across 16 advanced economies from 1870–present despite exhibiting 2x lower volatility, leading to housing's emergence as a lower-risk diversification component that challenges traditional asset pricing models.
Analyzing data from 1870 to the present across 16 advanced economies, housing returns in the long run are comparable to equities but exhibit lower volatility and lower covariance with consumption growth. This suggests that housing offers a more stable investment option with less risk exposure compared to equities. The findings indicate that the implied risk aversion parameters for housing wealth and total wealth are significantly larger than those for equities, often by a factor of 2 or more. This challenges traditional models and suggests that factors like limited participation, idiosyncratic housing risk, transaction costs, or liquidity premiums play minimal roles in resolving the risk premium puzzle. Consequently, housing emerges as a viable component of a diversified investment portfolio, offering substantial returns with reduced risk.
