Why has secular stagnation lost its mass appeal, and has it disappeared forever? Was it all a case of crying wolf?

Lawrence Summers has always made it clear that in his mind secular stagnation was a hypothesis, not a proven reality, especially in the US. He and others have argued that the combination of very low global GDP growth, alongside falling real interest rates, could be caused by two factors: (i) inadequate global demand, stemming from low business investment, high savings rates in Asia, wide disparity in income distribution and rising risk aversion; and (ii) inadequate global supply, stemming from falling productivity growth, and slowing growth in the labour force....MORE
