In the context of the AS/AD model, if business confidence incrases, we would expect:   Real GDP to increase and the price level to be indeterminate  Real GDP and the price level to increase for sure  Real GDP to increase and the price level to decrease for sure  Real GDP to decrease and the price level to increase for sure

MS, MS, MS, 0 $80 100 120 Amount of Money Demanded and Supplied Price Level Multiple Choice 0 Q₂ Real GDP Investment Demand $40 50 60 Investment -AD, (-$60) AD, $40) AD₂ ($50) Refer to the diagrams. The numbers in parentheses after the AD₁, AD2, and AD3 labels indicate the levels of investment spending associated with each curve. All figures are in billions. If the MPC for the economy described by the figures is 0.8. an increase in the money supply from $80 to $100 will shift the aggregate demand curve rightward by $50 billion at each price level. an increase in the money supply from $80 to $100 will shift the aggregate demand curve leftward by $40 billion at each price level.

The AD/AS graph illustrates an inflationary gap when the equilibrium level of real GDP is substantially to the left of potential GDP or the LRAS curve. substantially to the right of potential GDP or the LRAS curve. equal to full employment vertical
