Consumer spending decreases and total demand falls during a recession, which allows the government to implement a countercyclical policy to the way the economy is moving. Such a countercyclical policy would result in the intended expansion of output (and employment), but would also raise prices because it would expand the money supply. Increased demand will put pressure on input costs, particularly labor, as an economy draws closer to operating at maximum capacity.
