What distinguishes Keynesians from other economists is their belief in activist policy to reduce the amplitude of the business cycle.
Rather than seeing unbalanced government budgets as wrong, Keynes advocated so called that act against the direction if the business cycle.
These two paragraphs are from the economics article that I've been reading recently, and I'm not sure about the meaning of 'so called that act' in this context. From what I understood, this phrase is a paraphrasing of 'unbalanced government budgets', but I'm not sure if I'm getting it right. Can someone please explain how this phrase is used in this context?
