From The Guardian:
"But some economists point out that more spending will not necessarily translate into a much bigger hole in the public finances. Martin Beck, from the consultancy Oxford Economics, believes increasing borrowing to fund more spending or tax cuts would help the economy grow faster, which in turn could speed up deficit reduction."
“There’s a strong case for doing more fiscal loosening,” said Beck. “It could boost demand. It might not be completely self-financing but the idea you wouldn’t get more activity from more spending and tax cuts is silly and higher activity generates tax revenues.”
