“…First, in terms of the relevance restriction, previous research shows that stock returns are significantly related to a firm's financing (e.g., Myers, 1977;Myers, 1984;Baker and Wurgler, 2002;Welch, 2004) and investment decisions (e.g., Lamont, 2000;Cooper et al, 2008;Liu et al, 2009;Titman et al, 2004). To the extent that trade credit is one of the most important sources of financing for customers (Brick and Fung, 1984;Petersen and Rajan, 1997;Mateut et al, 2006) as well as a relevant form of (short-term) investment for suppliers (e.g., Abdulla et al, 2020), it should be highly correlated with stock returns. Empirically, previous evidence indeed documents a strong association between trade credit and stock returns (Hill et al, 2012;Goto et al, 2015;Albuquerque et al, 2013).…”
