Abstract
This dissertation examines certain aspects related to corporate innovation and their effect on shareholder wealth. The first essay examines whether patent publication prior to patent granting has real effects on the value of patents and overall firm value, particularly for small innovative firms. The American Inventors Protection Act of 1999 made it such that patents filed on or after November 29, 2000 would be published prior to being granted. The empirical analyses show that early patent publication reduces patent value, likely because the market assumes that competitors have time to adjust to previously published innovations. In addition, early patent publication can reduce the value of patents granted to small firms by up to twice as much as it reduces the value of those granted to all firms. The next essay explores the value of green patents and the response of institutional investors to green innovation. According to empirical tests, green innovation is valuable to the firms receiving green patents and some institutional investors recognize and reward this innovation effort. The portfolio weight of firms with green patents also increases within these institutions' holdings. Notably, some results suggest that institutional investors only reward green patenting at firms that also have strong Environmental, Social, and Governance (ESG) scores.
