Suppose the saving rate is greater than the golden rule saving rate (sG). First, explain what must happen to the saving rate in order to increase steady state consumption. Second, what are the advantages and disadvantages of this policy to increase steady state consumption

What will be an ideal response?

The saving rate must decrease. This will cause an initial increase in consumption per worker. As the economy responds to this reduction in s, K/N and Y/N will fall. In fact, C/N will rise (as long as the drop in s does not go past the golden rule rate) as well and eventually exceed its initial level. The advantage of such a policy is that it will increase C/N initially and in the long run (given the previous qualifier). The are few if any disadvantages. It is possible to cut s too much (this has not been discussed here).
