please answer everything and correct thankyou

Answer 1

(16) (D)

An open market sale (purchase) of securities will decrease (increase) money supply, which increases (decreases) interest rate.

(17) (A)

Lower interest rate increases investment, increasing aggregate demand and shifting AD curve rightward.

(18) (B)

Open market purchase increases aggregate demand, shifting AD curve rightward, which increases price level, causing SR Philips Curve to shift downward.

(19) (A)

Monetary policy changes aggregate demand, shifting AD curve.

(20) None of the options is correct. The correct answer should be: Supply, Rightward, Falls. Explained below:

Open market sale decreases aggregate demand. AD shifts left, decreasing price level. In long run, lower price level decreases production cost which increases firm output. Aggregate supply rises, shifting SRAS curve rightward which further decreases price level.

In following graph, AD0, LRAS0 and SRAS0 are initial aggregate demand, long-run aggregate supply and short-run aggregate supply curves intersecting at point A with initial price level P0 and real GDP (potential GDP) Y0. The open market sale decreases aggregate demand, shifting AD curve leftward, decreasing both price level and real GDP in short run. In the graph, AD0 shifts left to AD1, intersecting SRAS1 at point B with lower price level P1 and lower real GDP Y1.

In long run, SRAS0 shifts right to SRAS1, intersecting AD1 at point C with further lower price level P2 and real GDP restored to Y0.
