So, what do you do about the problem of secular stagnation? Again here there is divergence of opinion. Some still seek to treat the phenomenon as if it were a variant of the liquidity trap issue. Most notable here is Paul Krugman, who continues to hope that massive quantitative easing backed by strong fiscal stimulus will push the economy back onto a healthy path. But if the issue is secular stagnation, and the root is population ageing and shrinking, it is hard to see how this can be. The fact that Japan is just about to fall back into deflation 2 years after applying a monumental Quantitative Easing problem seems to endorse the idea that the problem may have no “solution” in the classical sense of the term.

There is this:

Finland has transited from being a country with a significant goods trade surplus, to being one with a structural deficit. Even the current account balance has now turned negative. And the country’s Net International Investment Position is also turning negative.

Hugh’s conclusion is this:

At the end of the day, only two things can be said with a fair degree of certainty: short term fiscal austerity won’t make any significant improvement and could help make things worse (this whole discourse is based on a misunderstanding about the problem) while short term stimulus won’t stimulate.

More sensible than most of what you will read on this topic.
