We study how information disclosure concerns shape the choice of limited partners (LPs) by venture capitalists (VCs). Late-2002 court rulings prevented public LPs from providing confidentiality to investment managers. The best-performing VCs, but not other managers, responded by excluding public LPs from their new funds. Lost access reduced public LP returns by 1.6 billion relative to 14 billion of their VC commitments. Legislation reducing disclosure, contracts limiting information access, and added fund-of-funds intermediaries helped restore access. These changes focused on protecting portfolio company information, highlighting the importance of proprietary information for VC investing and the potential costs of transparency.

Open banking (OB) empowers bank customers to share their financial transaction data with fintechs and other banks. New cross-country data shows 49 countries adopted OB policies, privacy preferences predict policy adoption, and adoption spurs fintech entry. UK microdata shows that OB enables: (i) consumers to access both financial advice and credit; (ii) SMEs to establish new lending relationships. In a calibrated model, OB universally improves welfare through entry and product improvements when used for advice. When used for credit, OB promotes entry and competition by reducing adverse selection, but higher prices for costlier or privacy-conscious consumers partially offset these benefits.
