Appearance of Unstable Monopoly State Caused by Selective and Concentrative Mergers in Business Networks

Abstract Recently, growth mechanism of firms in complex business networks became new targets of scientific study owing to increasing availability of high quality business firms’ data. Here, we paid attention to comprehensive data of M&A events for 40 years and derived empirical laws by applying...
