In June, Krugman and Richard Layard launched "A manifesto for economic sense", where they call for greater use of stimulatory fiscal policy to reduce unemployment and boost growth. By mid-2012, with the ongoing Euro crisis and persistent high unemployment in the US, there had been renewed consideration of stimulus policies by European and American policy makers but no return to the pro-stimulus consensus that existed in 2009. After the 2012 G8 summit, leaders issued a statement recognising the range of opinions concerning the best measures to strengthen their economies.
