“…Our use of patenting as a proxy for innovation activities has become standard in the innovation literature (e.g., Subramanian (2009), Hsu, Tian, andXu (2014), Acharya, Baghai, and Subramanian (2013), (2014), Chava, Oettl, Subramanian, and Subramanian (2013), Sapra, Subramanian, and Subramanian (2014), and Bloom et al (2016)). Moreover, the literature has shown that patents predict economic growth, aggregate stock market value, and firm profitability (Hsu (2009), Hirshleifer, Hsu, andLi (2013), and Kogan, Papanikolaou, Seru, and Stoffman (2017)), which supports our use of patent data to examine the real effects of policy and policy uncertainty.…”
