Fiscal Policy and Savings

LONG run and sustained...

It depends what the spending is for.

Boosting the short run implies a tradeoff, and a distortion in market incentives for long run efficient savings.

lower long run savings is likely to lower long run living standards regardless of source. likely, not certain.

I would give a different answer depending on whether we were talking about Brazil or China.

Important question with an answer that depends on too many factors for a flippant response on my part.

if we are talking long-run

Only an unlikely exotic economy could over come the basic principle that more now means less later.

Artificial depression of saving, which is the (unintentional) effect of many govt policies, reduces welfare unless itoffsets some distortion

Not everywhere and always, but probably here and now for most such policies.

Poorly worded and loaded question.

Unclear what is meant by a "spending policy that boosts consumption."
