“…Further, Chen, Lesmond, and Wei (2007) study the role of liquidity in the form of zero-return days, whereas Bao, Pan, andWang (2011), Dick-Nielsen, Feldhütter, andLando (2012), and Friewald, Jankowitsch, and Subrahmanyam (2012) investigate various proxies for liquidity, such as the measures of Roll (1984) and Amihud (2002). Lin, Wang, andWu (2011), De Jong andDriessen (2012), Acharya, Amihud, and Bharath (2013), and Bongaerts, de Jong, and Driessen (2017) examine bond returns instead of yield spread changes, showing that liquidity or liquidity risk matters in pricing bonds.…”
