By squeezing credit and term spreads, the business models of banks, insurance companies and pension funds are put at risk, as is their lending.

This explanation contrasts sharply with the hypothesis of a savings glut: little more than a tautology for slow demand growth.
这种解释与储蓄过剩的假设形成了鲜明对比：那不过是需求增长缓慢的同义反复。
On the supply side, misallocations slow growth which again leads to monetary easing, more misallocation and still less growth.

This explanation seems far more convincing than secular stagnation in an era of extraordinary technological advances.
这种解释似乎远比非凡技术进步时代的长期停滞更令人信服。
Accepting the importance of these varied effects also undercuts the popular argument that central banks must reduce the financial rate of interest whenever the natural rate of interest (the expected rate of return on capital) declines.
接受这种种后果的重要意义，还削弱了这样一种流行说法：只要自然利率（预期的资本回报率）下降，央行就必须降低金融利率。
If expected profits have collapsed as a side effect of past monetary policies, this hardly seems to justify maintaining such polices.
