Commonality in Liquidity and Real Estate Securities∗

We conduct an empirical investigation of the pricing and economic sources of commonality in liquidity in the U.S. REIT market. Taking advantage of the specific characteristics of REITs, we analyze three types of commonality in liquidity: within-asset commonality, cross-asset commonality (with the stock market), and commonality with the underlying property market. Using a conditional approach for our pricing test, we find evidence that the three types of commonality in liquidity are priced in REIT returns but only during bad market conditions. Importantly, we also find that a linear approach would have underestimated the role of commonality in liquidity risk. This explains (at least partly) the small impact of commonality on asset prices documented in the extant literature. Finally, our analysis of the determinants of commonality in liquidity favors a demand-side explanation
