آیا شرکت های مخابراتی مخابرات ایجاد ارزش می کنند؟ تجزیه و تحلیل طولی شرکت های مخابراتی ایالات متحده از سال 1996 تا 2005

Takeovers by telecommunications carriers have surged during between 1996 and 2005, stimulated by the Telecommunications Act of 1996. In this study, we hypothesize and test the short-term and long-term performance of telecommunications carrier mergers and acquisitions (M&As) between 1996 and 2005 according to three main categories (strategic types, bidder characteristics, and payment methods). For short-term performance, this study investigates abnormal market returns of bidding firms after M&A announcements and our study shows that telecommunications carrier M&A announcements do result in a significant increase in shareholder wealth in the short run. However, from a long-term perspective, which has been investigated in terms of the survival rate and the operating performance after M&As, the telcos experience a statistically significant decrease of up to 10%. The results also show that though strategic type, bidder characteristics, and payment method play an important role in the value creation of M&As in the short term, only the bidder size matters in the success of M&As over a long period of time.
