We create a novel dataset to examine the recent rise in dual-class IPOs. We document that dual-class firms have different types of controlling shareholders and wedges between voting and economic rights, and that the increasing popularity of dual-class structures is driven by founder-controlled firms. We find that founders’ wedge is greater when founders have stronger bargaining power. The increase in founder control over time is due to greater availability of private capital and technological shocks that reduced firms’ needs for external financing. Stronger bargaining power is also associated with a lower likelihood of sunset provisions that terminate dual-class structures.

We examine the spillover effects of local initial public offerings (IPOs) on new business formation. An IPO in a local area is associated with a 1%–4% increase in new business registrations, and this effect is particularly pronounced in counties facing higher economic uncertainty. New business registrations are significantly influenced by the extent of EDGAR downloads related to the IPO firm's public disclosures and the information in the IPO firm's S‐1 disclosure. The findings highlight the role of IPOs in conveying crucial information through signaling of potential success prospects and additional provision of information through disclosures. A field survey of 503 entrepreneurs further supports these conclusions.
