We examine the impact of the enactment of the Market Abuse Directive (MAD) and the Prospectus Directive (PD) across 18 EU countries on seasoned equity offerings (SEOs). Using a difference-in-differences methodology, we document a significant reduction in earnings management, improved post-SEO stock return performance, and a decline in the adverse reaction to SEO announcements following the enactment of MAD. We find similar, albeit weaker, results post-PD. The impact is stronger in countries with high ex-ante institutional quality. Our results suggest that the enactment of these directives leads to improvements in information quality, which reduces information asymmetry around SEOs.

We examine the impact of corporate board reforms on firm value in 41 countries. Using a difference-in-differences design, we find that board reforms increase firm value. Reforms involving board and audit committee independence, but not reforms involving separation of chairman and chief executive officer positions, drive the valuation increases. In addition, while comply-or-explain reforms result in a greater increase in firm value than rule-based reforms, the effects of reforms are similar across civil law and common law countries. Further investigation shows that the subsequent change in board independence plays an important role in explaining the effectiveness of the reforms.
