The federal government increases taxes in an attempt to reduce a budget deficit. c. The U. S. economy experiences 4 percent inflation.

a. AD curve will shift to the right

b. AD curve will shift to the left

c. Movement along the AD curve.

b. When The federal government increases taxes in an attempt to reduce a budget deficit. This will cause a change in consumption as people will have less money to spend since disposable income has been reduced, and it will cause the aggregate demand curve to shift inwards to the left.

c. A 4 percent in US inflation will bring about a change in price level and there will be a movement along the aggregate demand curve.
