Explaining the diversity in shareholder lockup agreements

This paper investigates whether shareholder lockup agreements in France and Germany mitigate problems of agency and asymmetric information. Despite minimum requirements in terms of the length and percentage of shares locked up, lockup agreements are not only highly diverse across firms but also across the different shareholders of a single firm as most firms have different agreements in place for executives, non-executives and venture capitalists. The diversity across firms and types of shareholders can be explained by firm characteristics - such as the level of uncertainty - as well as the type and importance of each shareholder within the firm.
