21) The IS curve is Y = 20 – 1.5r, and the aggregate demand curve is Y = 15.5 – 0.3π. When the
interest rate is 7 percent, the inflation rate is ________ percent.
A) 14.6
B) 9.5
C) 3.6
D) 20
E) none of the above
22) The IS curve is Y = 20 – 1.5r, and the aggregate demand curve is Y = 15.5 – 0.3π. When the
inflation rate is 3 percent, output is ________.
A) 20
B) 14.6
C) 9.5
D) 3.6
E) none of the above
23) The aggregate demand curve is Y = 15 – 0.2π when the inflation rate falls from 6 percent to 5
percent. Then, output increases from 13.8 to 17. The response of monetary policy to the inflation
decline has been ________.
A) autonomous tightening
B) automatic adjustment
C) autonomous easing
D) to increase autonomous spending
E) none of the above
24) Suppose the monetary policy curve is r = 5 + 0.8π, and the current values for output and
inflation are 16.8 and 2 percent, respectively. An increase in global resource prices pushes the
inflation rate to 4 percent. Policy makers estimate that the monetary policy in place, responding
to 4 percent inflation, will bring output down to 13.6, a decline considered excessive. Instead,
they implement an autonomous easing of monetary policy to lower output from 16.8 to 16.
Assuming no change in the slope of the monetary policy curve, determine the new curve.
