{"title":"Q-Theory and Acquisition Returns","authors":"K.

The theory predicts that larger acquirers optimally choose larger targets, but of smaller relative size. Dollar gains increase, but percentage returns decrease as acquirers get larger. Since later deals are made by larger acquirers, returns appear to decline with experience. Using a panel dataset of repeat acquirers, empirical tests support the predictions of q−theory. In contrast, I find only weak support for an agency explanation and no support for a hubris story. I also reject the theory that declining returns result from market anticipation of later deals.","PeriodicalId":439904,"journal":{"name":"The Role of Financial Advisors & Learning in Mergers & Acquisitions","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126205602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
