After using your forecasting model for six months, you decide to test it using a tracking signal. Here are the forecast and actual demands for the six-month period: PERIOD FORECAST ACTUAL May 450 480 June 500 560 July 550 380 August 590 465 September 635 650 October 715 610 a. Find the tracking signal. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)

You are given the following information about aggregate demand at the existing price level for an economy: (1) consumption = $400 billion, (2) investment = $40 billion, (3) government purchases = $90 billion, and (4) net export = $25 billion. if the full-employment level of gdp for this economy is $600 billion, then what combination of actions would be most consistent with closing the gdp gap here?
