论文简介:Previous research suggests that insiders’ shareholding pledges are  associated with agencyproblems. However, how investors evaluate and react to  such behavior is less clear. Weinvestigate the stock market reactions to three  insiders’ shareholding pledging regulatoryevents in Taiwan. The first event in  2007 limited the amount of bank loans as a percentage ofinsiders’ stock pledging  value (the pledge value rule event). The second event is the firstreading of the  2011 Company Act amendment (the first reading event), which was an attemptto  improve minority shareholder protection by restricting the voting rights of  pledged sharesexceeding one-half of the shares held by a director on election.  The third event is the passage ofthe amendment (the passage event). We show that  firms with insiders making share pledgesexperience significantly higher stock  returns around events compared to those without suchinsiders. In addition, the  results are more significant for firms with small board of  directors’shareholdings, when the agency problem is likely to be more severe.  These results areconsistent with the alignment hypothesis that firms that are  less compliant with the rulesbenefit more from legislative changes. We also find  that institutional investors increased theirshareholdings of pledging (less  compliant) firms after the passage event, indicating that areduction in agency  problems increases institutions’ willingness to hold shares of lesscompliant  firms. Our results have important implications on how ameliorating the legal  systemcan help to improve investor protection.
