Blanchard & Fisher (1989) Lectures on Macroeconomics英文版229-230页
If the Diamond economy is dynamically inefficient, there is a steady state with a positively valued bubble at point E. The interest rate is then equal to n, so the bubble removes the inefficiency and the economy is at the golden rule.
问题:泡沫的出现如何消除经济动态无效,如何使得利率趋于n,特别是由于Diamond经济中虽然个人储蓄因为泡沫的产生而降低,从而使得资本存量降低,资本过度积累现象消除,但泡沫所占用的资本也并未用于个人消费,对于个人效用乃至社会福利的提高在哪里?
