Answer to Question 1
Fiscal policy affects aggregate demand through government expenditure, transfer payments and taxes. Because government purchases are a component of total spending, a change in government expenditure directly changes aggregate demand. A change in transfer payments changes disposable income which, in turn, changes consumption expenditure and aggregate demand. Finally, taxes alter disposable income and thus impact consumption expenditure and aggregate demand.
