In sum, the case for describing the world as being in a debt supercycle is both theoretically and empirically compelling. The case for secular stagnation is far thinner. It is always very difficult to predict long-run future growth trends, and although there are some headwinds, technological progress seems at least as likely to outperform over the next two decades as it is to exhibit a sharp slowdown.Remove the debt and growth will return. Preserve the debt and stagnation sets in.
Again, the US appears to be near the tail end of its leverage cycle, Europe is still deleveraging, while China may be nearing the downside of a leverage cycle. Though many factors are at work, the view that we have lived through a debt supercycle, marked by a severe financial crisis (Lo and Rogoff 2015), is far more constructive for policy analysis than the view that the world is suffering from long-term secular stagnation due to a chronic shortfall of demand.
