Does takeover activity affect stock price crash risk? Evidence from international M&A laws

We exploit the staggered initiation of merger and acquisition (M&A) laws across countries as a plausibly exogenous shock to the threat of takeover to examine whether the market for corporate control has a real effect on firm-level stock price crash risk. Using a difference-in-differences regression on a large sample of firms from 32 countries, we find that stock price crash risk significantly decreases following the passage of M&A laws. This effect is stronger for firms domiciled in countries with poorer investor protection and information environments and for firms with weaker firm-level governance. Further, financial reporting opacity and over-investment significantly decrease in the post-M&A law periods. Our study suggests that an active takeover market has a disciplining effect on managerial bad news hoarding and leads to lower future crash risk.
