“…Several researchers have examined the relationship between the characteristics of members of boards of directors and information asymmetry. In previous studies, proxies for information asymmetry represent information shared externally with the market and analysts, for example, bid‐ask spread (Fehle, ; Goh, Lee, Ng, & Ow Yong, ; Kanagaretnam, Lobo, & Whalen, ; Linck et al, ), analyst following (Goh et al, ; Shiah‐Hou, ), and forecast error (Byard et al, ; Goh et al, ).
