A need to update the vertical mergers guidelines has been a widespread view within the academic community. Salop and Culley (2014) have suggested a comprehensive list of reforms. In Europe, similar concerns have been voiced about the spate of vertical mergers that involve major online platforms mainly Google, Apple, Facebook, and Amazon (GAFA) (The Economist, March 23, 2019 at 11). This paper examines two companies outside the postal sector to understand the influence of Big Data on markets, looking at Amazon, which has acquired numerous vertically related companies, and the newly merged AT&T/Time Warner. A key theme of this paper is that traditional vertical merger theories have not focused clearly on Big Data’s effects on market behavior and performance. To fill the gap, a new “matrix” approach is introduced to examine the potential market imperfections caused by uneven availability of data. All this can be helpful for understanding the challenges that may confront postal companies attempting to expand into information rich markets.
