Based on the data published by the ITU in its 2013 edition of Measuring the Information Society (MIS), detailing the capex and global telecom revenues, crossed with the breakdown of the growth of IMF/WB economies (see more information here), it may be observed that telcos increased their productivity, as a result of central countries financial problems and because the adjustment also affected developing countries. The erratic behavior of the company revenues rate, is another reason that explains the concentration processes recorded last year.
