Kenneth Rogoff, April 30, 2019, Opinion, “The financial crisis of 2008 may have started in the US banking sector but it went on to unleash the deepest global recession since the Great Depression. The year 2009 became the first on record where global GDP contracted in real terms and the lost growth resulting from the crisis and ensuing recession has been estimated at over $10 trillion (more than one-sixth of global GDP in 2008).” Link
