Multiplier
= change in real GDP / initial change in spending = 1/MPS = 1/(1-MPC)
The crowding out effect
A reduction in private spending as a result of higher interest rates generated by budget deficits that are financed by borrowing in the private loanable funds market. Usually when government expenditures are very high
Automatic or built-in stabilizers
Built in features that tend automatically to promote a budget deficit during a recession and a budget surplus during an inflationary boom, even without a change in policy. The positive idea behind automatic or but in stabilizers is that they institute countercyclical fiscal policy without the delays associated with legislative action
Private domestic economy equation :
C + 1
Employment Act of 1946
Committed the Federal Gov't to "promote maximum employment, production, and purchasing power." It created the Council of Economic Advisers and the Joint Economic Committee of Congress.
Net Exports
Exports minus imports Xn = X - M
Investment Spending
Investment spending by the business sector does not depend on the level of income, but on the interest rate that businesses have to pay for their funds to make investment expenditures.
The Aggregate Expenditures Model
Is a model of how the level of GDP is determined. The categories include personal consumption expenditures of households, investment expenditures by the business sector, government spending and net exports. GPD = C + Ig + G + Xn
Consumption expenditures decrease by
MPC x the change in disposable income
Saving decreases by
MPS x the change in disposable income
DI =
PI - T = C + S
The standardized budget also called the full employment budget
Provides a way to tell if discretionary fiscal policy is expansionary or restrictive. The full employment budget shows what the budget deficit or surplus would be if the economy were at full employment and allows us to distinguish between the cyclical deficit or surplus which results from built in stabilizers and the surplus or deficit which results from discretionary fiscal policy.
The offsetting effects of pro-cyclical state and local government finance
State government must spend less or tax more rather than go into a deficit. Revenues must equal expenditures.
Marginal Propensity to consume
The amount by which consumption expenditures change when income increases by one addition dollar ceteris paribus. The MPC is the slope of the consumption function MPC = Change in consumption expenditures / change in income
Budget Deficit
The amount by which government expenditures exceed government revenues in a given year.
Budget Surplus
The amount by which government revenues exceed government expenditures in a given year
The Consumption and Savings Functions
The consumption function describes personal consumption expenditures as a function of household income. If there is no government or foreign sector, then GDP = NI = PI = DI As a household income increases, consumption expenditures increase and vice versa. At very low levels, households my spend more than their incomes by spending out of savings. At higher levels of income households save some of their income and consumption expenditures are less than income. DI = C + S we can also derive that S = DI - C
Public Debt
The total accumulation of the deficits minus the surpluses the federal government has incurred through time.
Net income determinants of consumption and saving include :
Wealth , expectations, taxes, household debt Changes in these determinants will cause the consumption and saving functions to shift
The main determinant of investment demand is the expected rate of return on investment which depends on :
acquisition, maintenance, and operating costs business taxes technological change stock of capital goods on hand expectations changes in these determinants of investment demand will cause the investment demand curve to shift
The multiplier process causes equilibrium GDP to
decrease by the multiplier times the change in spending
Expansionary fiscal policy
designed to stimulate the economy out of a recession involves increased government spending or reductions of taxes. Expansionary fiscal policy will increase the government budget deficit. Increased government spending or tax reductions shift the aggregate demand curve to the right. In the horizontal or upward sloping portions of the aggregate supply curve this will increase real GDP Apart of Discretionary or active fiscal policy
Restrictive fiscal policy
is designed to deal with demand pull inflation involves decreased government spending or increases in taxes. Restrictive fiscal policy will reduce the government budget deficit or create a budget surplus. Decreased government spending or tax increases shift the aggregate demand curve to the left. This reduces the aggregate price level in the upward sloping or verticle portions of the aggregate supply curve.
Saving and planned investment are only equal at the equilibrium
level of GDP
Change in GDP
multiplier x change in spending Allows for the finding of the new equilibrium point
The equilibrium level of GDP
occurs where aggregate expenditures equal GDP GDP = C + I
Inflationary gap
refers to the amount by which aggregate expenditures would have to be decreased to reach the full employment level of GDP
Recessionary gap
refers to the amount by which aggregate expenditures would have to be increased to reach the full employment level of GDP
The balanced budget multiplier
refers to the fact that if government spending and taxes both increase by an equal amount so that the government's budget remains in balance, equilibrium will increase by that same amount
Fiscal Policy
refers to the use of government spending and taxes to influence employment, output, and the price level
ONLY when aggregate expenditures are equal to GDP is:
saving equal to planned investment which is another way to think of the equilibrium condition for GDP
When aggregate expenditures are greater than GDP, from the equilibrium level of GDP from the point of view of saving and investment
saving is less than planned investment
Marginal propensity to save
the amount by which saving changes when income changes by one additional dollar, ceteris paribus. The MPS is the slope of the saving function MPS = Change in saving / change in income MPC + MPS = 1
Average propensity to save
the percent of income saved APS = S/DI APC + APS = 1
Average propensity to consume
the percent of income spent on consumption APC = C/DI
When aggregate expenditures are less than GDP
there is an unplanned decrease in inventories, and businesses increase their level of output i.e., GDP decreases . Actual investment is less than planned investment
