Data and Code for: Common Ownership and Entrepreneurship

This is data and code to accompany the article "Common Ownership and Entrepreneurship." In the article, we complement the literature on common ownership by presenting two new observations from entrepreneurial startups. First, given the increase in common ownership of startups by VC investors, inclusion of high-value startups in standard common ownership measures may actually increase aggregate measures of common ownership. Second, we suggest that even if public-firm common ownership leads to collusive inefficiency and higher prices in the short-term, it may also create opportunities for entry of innovative, high-growth startups. Consistent with this, we document that entrepreneurial activity and common ownership of startups tends to be higher in industries with higher common ownership among public firms.
