“…For instance,Mauer and Sarkar (2005),Shibata and Nishihara (2012),Nishihara and Shibata (2013),and Sundaresan, Wang, and Yang (2015) theoretically examined the effects of financing sources, whereasHo, Tjahjapranata, and Yap (2006),Brown, Fazzari, andPetersen (2009), andHall andLerner (2009) empirically examined the effects of financing sources in R&D projects.3 Some papers distinguish the lag between project inception and completion (the gestation lag) and project completion and commercial application (the application lag) (e.g.,Pakes & Schankerman, 1984). For simplicity, we assume that the total lag is equal to T 1 .4 An alternative approach for modeling rival preemption is a game theoretic real option model (e.g.,Huisman, 2001;Nishihara & Shibata, 2010;Pawlina & Kort, 2006;Shibata, 2016;Weeds, 2002).…”
