It depends entirely on where it's added. If it is added where it will directly translate to demand (e.g. eliminating payroll tax) then you will get more spending, which will cause businesses to hire, take on loans to meet the new demand. At some point if you keep adding, you will surpass the ability of the market to absorb the demand and you will get inflation. If it is added on top of already flush corporate balance sheets (e.g. eliminating corporate taxes), then you most likely won't see much difference in the current environment. They won't use it to hire more people because the demand isn't there. Loans in and of themselves don't add net dollars to the private sector, as they create a liability for the exact amount of the loan (plus interest). For the domestic private sector to experience a net increase in financial assets, either the sovereign government (whoever's name is on the money) or the foreign sector must increase its deficit.
