“…One set of researchers finds that new product announcements do not contribute significantly to the value of firms (Eddy and Saunders, 1980;Wittink et al, 1982;Koku et al, 1997;Koku, 1998;Markovitch and Steckel, 2012). Another set of researchers, however, argue that new product announcements are positively associated with shareholder value (Woolridge and Snow, 1990;Chaney et al, 1991;Chaney and Devinney, 1992;Zantout and Chaganti, 1996;Chen and Ho, 1997;Akhigbe, 2002;Chen, 2008;Lee and Chen, 2009;Sood and Tellis, 2009;Koku, 2009;Lin and Chang, 2012;Hu et al, 2013). Further, the third set of researchers is of the opinion that the new product announcements are negatively associated with the shareholder value (Pardue et al, 2000).…”
