Answer to Question 1

Aggregate demand increases and the AD curve shifts rightward if: expected future income, expected future inflation, or expected future profits increase; government expenditure increases or taxes are cut; the quantity of money increases and the interest rate is cut; the exchange rate falls; or foreigners' income increases. The reverse changes decrease aggregate demand and shift the AD curve leftward.

A
