The Multiplier Revisited ●  government purchases of goods and services   total spending directly through the G component of C + I + G + (X - IM). ●  taxes   total spending indirectly by lowering disposable income and, thus, reducing the C component of C + I + G + (X - IM). ●  government purchases of goods and services   total spending directly through the G component of C + I + G + (X - IM). ●  taxes   total spending indirectly by lowering disposable income and, thus, reducing the C component of C + I + G + (X - IM).

The Choice Between Spending and Tax Policy ●The choice between G and T reflects a difference in opinion about the desirable size of the government sector. ♦Advocates of small government prefer: ■To lower T in order to stimulate output ■To lower G to control inflation ♦Advocates of big government prefer: ■There is nothing about an activist fiscal policy that implies a preference for big government. ●The choice between G and T reflects a difference in opinion about the desirable size of the government sector. ♦Advocates of small government prefer: ■To lower T in order to stimulate output ■To lower G to control inflation ♦Advocates of big government prefer: ■There is nothing about an activist fiscal policy that implies a preference for big government.
