Full marks require graphical representation, written explanation of equations derived and well presented and explained algebra. Question A3: As equation (4) above.

2 Question A4: To calculate the long-run equilibrium level of harms, insert the level of capability output Y* = cd into the aggregate demand curve (4) and solve for P: P* = 0.50 (long-run equilibrium level of prices) (7) To calculate the rate of provoke that is consistent with this long-run equil ibrium level of output and prices, second-! stringer pitcher the long-run equilibrium values of output ( Y * ? 400 ) and prices ( P * ? 0.5 ) into the LM equation (3): r * ? 5 percent (8) At Y=310, the preservation operates below potential hence prices will gradually fall. As the aggregate price level falls, sincere money supply increases and the rate of interest declines shifting the economy along the AD curve.
