The use of equity incentives is significantly greater in countries with stronger insider trading restrictions, and these higher incentives are associated with higher total pay. These findings are robust to alternative definitions of insider trading restrictions and enforcement, and to panel regressions with country fixed effects. We also find significant increases in top executive pay and the use of equity-based incentives in the period immediately following the initial enforcement of insider trading laws. We conclude that insider trading laws are one channel through which cross-country differences in pay practices can be explained.

Abstract Material adverse change (MAC) clauses are a ubiquitous feature of acquisitions and exhibit substantial cross-sectional variation in the number and types of events that are excluded from being material adverse events (MAEs). MAEs are the underlying cause of 69% ofacquisition terminations and 80% of renegotiations. These renegotiations lead to substantial changes in the price offered to target shareholders. Acquisitions with fewer MAE exclusions are characterized by wider arbitrage spreads during the acquisition period and are associated with higher offer premiums. We conclude that MAC clauses have an economically important impact on the dynamics of corporate acquisitions.
