This study looks into the behavior of privately held firms in Colombia that participate in waves of mergers and acquisitions between 1995 and 2008. The study finds evidence in which experienced firms that perform mergers and acquisitions late in waves show stronger performance as measured by their return on assets. The firms that fall prey to the bandwagon effect and perform M&As; at the peak of a wave show the weakest performance in munificent industries. The study discusses the rationality behind strategic waiting in environments with lax contract enforcement and limited information about acquisition targets.
