In this paper, we show that too strong investor protection may harm small firms and entrepreneurial initiatives, which contrasts with the traditional “law and finance” view that stronger investor protection is better. This situation is particularly relevant in equity crowdfunding, which refers to a recent financial innovation originating on the Internet that targets small and innovative firms. In many jurisdictions, securities regulation offers exemptions to prospectus and registration requirements. We provide an into-depth discussion of recent regulatory reforms in different countries and discuss how they may impact equity crowdfunding. Building on a theoretical framework, we show that optimal regulation depends on the availability of an alternative early-stage financing such as venture capital and angel finance. Finally, we offer exploratory evidence from Germany on the impact of securities regulation on small business finance.
