“…In economic terms, convergence in technology because of a peer firm converging on the focal firm's technology space is associated with a 154% and 65% increase in the odds of becoming a benchmark peer in columns 1 and 2, respectively, supporting our main findings that technology convergence affects the focal firm's benchmarking choice and that the effect is likely to be unrelated to other factors affecting the focal firm. 24 24 To further mitigate the endogeneity concern, we also examine the effect of the staggered rejection of the Inevitable Disclosure Doctrine (IDD) to exploit exogenous variations in employee mobility (and hence knowledge spillovers between firms) by potentially preventing the given firm's employees from being hired by rivals (e.g., Klasa, Ortiz-Molina, Sefling, and Srini (2018), Flammer and Kacperczyk (2019), Na (2020), andGu, Huang, Mao, andTian (2022)). In our context, the rejection of the IDD is likely to increase inventor mobility and hence reduce the protection of a firm's proprietary knowledge, which in turn would typically increase knowledge spillovers between firms.…”
