Econ 111 Exam 2
MPS =
change in saving/change in income
Aggregate Expenditures
consists. of the components of GDP that are measured by spending
Aggregate Demand Determinants
consumer spending, investment, government spending, net exports
When short run equilibrium is below full employment
the spending multiplier magnifies new spending (shifting AD toward long run equilibrium)
National Debt
the total accumulation of past deficits plus surplus
Aggregate demand slopes down due to
the wealth effect, export price effect, interest rate effect
short-run aggregate supply curve
the quantity of real GDP supplied and the price level.
Balanced budget multiplier is equal to
1
MPC + MPS =
1
There are four limitations to the effectiveness of discretionary fiscal policy
1.shrinking area of law-maker discretion 2.estimating potential GDP 3.economic forecasting 4.law-making time lag
Spending multiplier =
1/1-MPC
LRAS
A shift in the long run aggregate supply curve moves the economy to a new long-run equilibrium output
Example of MPC
If you spend $0.75 of each dollar you earn, your MPC is said to be equal to 0.75
The potential level of output
LRAS
mandatory spending
Medicaid, Medicare, Social Security, Income Security Programs
Discretionary spending
Military Spending, Infrastructure/Transportation, Education
0<MPC<1 is true or false
TRUE
If the cost of production increase, there is
a decrease in aggregate supply and the SRAS curve shifts leftward
Recessionary gap
a negative difference between actual GDP and the potential GDP, occurs during recessions
Cost-push inflation
a negative supply shock reduces output and raises price, increasing AD will push output back to full employment but at even higher prices alternatively decreasing AD will reduce inflation but increase unemployment
Demand-pull inflation
a positive demand shock expands the economy beyond full employment output, higher input prices shift SRAS to the left until long-run equilibrium is restored, but at higher price level
automatic stabilizer
a tool of fiscal policy that increases or decreases automatically depending on changes in GDP and personal income
If the ultimate goal of fiscal policy aimed at aggregate supply is achieved, what happens to the aggregate price level and aggregate output?
aggregate price level decreases; aggregate output increases
Public debt
amount of money held by other (US/foreign banks, US citizens, foreigners, other countries)
Marginal Propensity to Consume (MPC)
an increase in your consumption for each extra dollar income in your income
Marginal Propensity to Save (MPS)
an increase in your savings for each extra dollar increase in your income
If the economy is at full employment, increases in government spending:
are primarily absorbed by price increases.
MPC =
change in consumption/change in income
crowding-out effect, if the government sells bonds to finance spending, _____ can eventually fall.
consumption and investment
AD shift factors
consumption, investment, government spending, net exports/imports
Determinants of Investment
expected profit, interest rates, government regulations, technological change
Spending multiplier is always
greater than tax multiplier
Crowding-out Effect
higher interest rates make consumers and business less likely to borrow for purchases and investment, therefore government debt crowds out consumptions and investments leading to a less productive future economy
Paradox of thrift
if households save more, the multiplier becomes smaller, leading to reduced output and income, which then leads to less saving
Y=AE
income
Aggregate income
income of everyone in the economy
Determinants of Consumption
income, expectations about the future, taxes, wealth, household debt
Expansionary Fiscal Policy
increase in government spending, cutting taxes
Things that shift the SRAS left
increase in input prices (oil and shipping costs), expected/increase inflation, a higher market power, taxes and regulations
Stagflation =
inflation + recession, period of economic recession with rising prices
what occurs to right of LRAS (potential level of output)
inflationary gap
Mandatory spending programs
interest on national debt, Medicare, social security
Public debt owned by U.S. banks, corporations, mutual funds, pension plans, and individuals is called _____ debt.
internally held
potential gdp
is independent of the price level.
Fiscal Policy
is the set of policies undertaken by the government to influence the economy, such as discretionary spending
A higher aggregate price level causes
lower aggregate output
Government spending includes
mandatory spending, discretionary spending, net interest
Discretionary spending
military spending, education, infrastructure/transportation
Inflationary gap
occurs when spending is above the full employment level
if technology increases, then in the long run
output is higher and prices are lower
Things that shift the LRAS
population/labor force, natural resources, technological resources, international trade
what occurs to left of LRAS (potential level of output)
recessionary gap
Contractionary Fiscal Policy
reduction in government spending, raising taxes
If interest rates rise, the burden of a nation's public debt will _____ and it will be _____ difficult to service its debt.
rise, more
Cost-push inflation occurs when:
rising resource costs reduce short-run aggregate supply.
If an economy is in a recession, what would expansionary fiscal policy do?
shift AD to the right
AD shift factors any decrease
shifts left
AD shift factors any increase
shifts right
Everything that shifts the LRAS also
shifts the SRAS, however not other way around
Aggregate demand curve
shows the output of goods and services (real GDP) demanded at different price levels
The "sticky-wage" hypothesis explains the
slope of the short-run aggregate supply curve
Things that shift the SRAS to the right
technological progress
average prosperity to consume (APC)
total consumption in a given period divided by total disposable income
AE= C + I
total spending
autonomous consumption
whatever is at zero
Where does long-run equilibrium occur?
where AD and LRAS intersect
Where does short-run equilibrium occur?
where AD and SRAS intersect
