Econintersect: McKinsey Global Institute has published a study of the rapid rise in global trade, finance, services and information in the twenty-first century. In 2012 the global flow of goods, services and finance amounted to $26 trillion, more than one-third of global GDP. Among the most dramatic changes has been an 18-fold increase in internet traffic in just seven years.
The 2012 flows of goods, services and finance actually was higher in 2007 than in 2013 as a result of an outsized flow in finance. In 2008 and 2009 there was a sizable contraction in international flows during the Great Recession, again driven more by finance flows than other factors.
