    Expenditure Multipliers

    The expenditure multiplier is the measure of the change in aggregate production caused by changes in autonomous expenditure¹. It is the inverse of one minus the slope of the aggregate expenditure line. The expenditure multiplier shows how a small change in expenditure can create larger changes in aggregate output.  Expenditure multipliers can be separated into simple expenditure multipliers and complex expenditure multipliers. Only induced consumption is in the simple expenditure multiplier, while the complex expenditure multiplier includes other induced variables. The multiplier will be greater than 1.0 because a change in autonomous expenditure will change induced expenditure.

    An expedniture multiplier is a crucial part of Keynsian economics and the usefulness of fiscal policy to stimulate sustainable economic growth. Consider an individual consumer that has been given $100 to spend. When he spends it, it becomes the income of another individual. This second consumer will save a portion and spend a portion - for example he spends 40% of it. Assuming that all individuals in this economy have the same marginal propensity to consume of 40%, then this process continues. In this simple multiplier, we find that for every $100 injected into the economy, the change in GDP will end up being approximately $167. So even if the government has to eventually repay the $100 through taxation, the economy still benefits through fiscal policy. 

    Complex expenditure multipliers have different combinations of induced components. Induced consumption, investment, and government purchases all raise the value of the expenditure multiplier, while induced taxes and imports decrease the expenditure multiplier’s value¹.

    Increase In Government Taxes

    A government is currently operating with an annual budget deficit of $40 billion. The government has determined that: --The marginal propensity to consume is 0.75. --To eliminate an inflationary gap and take into account the resulting change in the price level, the government must generate a net leftward shift in the aggrega

    What is the multiplier effect?

    What is the multiplier effect? Our expenditures are always greater than what our actual dollar value is. How does that work? Is this related?

    Calculate autonomous expenditure.

    The figure illustrates the components of aggregate planned expenditure on Turtle Island. Turtle Island has no imports or exports, the people of Turtle Island pay no income taxes, and the price level is fixed. a. Calculate autonomous expenditure. b.

    Assume that a hypothetical economy with an MPC of .8 is experiencing severe recession. By how much would government spending have to increase to shift the aggregate demand curve rightward by $25 billion? How large a tax cut would be needed to achieve this same increase in aggregate demand? Why the difference? Determi

    The IS Curve and a Steep Slope

    We can expect the IS curve to get steeper as: 1)-money demand becomes less sensitive to the interest rate 2)-the marginal propensity to save increases 3)-investment becomes more sensitive to changes in the interest rate 4)-the income tax rate decreases 5)-the expenditure multiplier increases

    Economic reactions

    An increase in the marginal propensity to _____will decrese the size of the expenditure multiplier (a) and therefore the IS curve will shift to the ____and become steeper. If people save more and spend less, firms will experience an increase in unintended inventories. Firms will respond by decresing production and national incom
