From a capital market perspective, the author analyzes Merger and Acquisitions transactions (M& A) and in-licensings in the pharmaceutical industry between 1998 and 2012. Utilizing the event study methodology, the volume shows that M& A experiences significant, negative cumulative average abnormal returns whereas in-licensings are able to create value. But what are the underlying value drivers which make a deal a success or a failure story? The author derives significant innovative determinants of success for both strategies.
