ZenithOptimedia Drops Estimates for 2013 Growth

Expects 3.9% Rise

ZenithOptimedia is revising its 2013 global economic growth estimates to 3.9 percent, to $518 billion, down from the 4.1 percent increase forecast in December. The Publicis Groupe media company said it made the change because 2012 turned out to be better than expected, making for tougher comparisons this year. By 2015, ZenithOptimedia predicts growth of 5.6 percent.
