Q

Aggregate Output: GDP

A

Market value of all final goods and services produced in a country/economy.

  • Produced during the period
  • Only goods that are valued in the market
  • Final goods and services only (not intermediate)
  • Rental value for owner occupied housing (estimated)
  • Government services (at cost)-not transfers

National income =

  • employees’ wages and benefits
  • +corporate and governmen tprofits pre-tax
  • +interest income
  • +unincorporated business owners’ income
  • +rent
  • +indirect business taxes - subsidies

(taxes and subsidies included in final prices)

Q

Aggregate Output: Deriving the Fundamental Relationship

A

GDP = C + 1 +G + (X - M) Total Expenditures

GDP = C + S +T Total Income

¢ + S + T = ¢ + I + G + (X - M)

S + T = I + G + (X - M)

S = I + (G - T) + (X - M)

Q

Aggregate Output: Fundamental Relationship

A

S = I + (G - T) + (X - M)

Savings = Investment + Fiscal Balance + Trade Balance

Saving are either invested, used to finance government deficit, or used to fund a trade surplus, when both exist.

Q

Aggregate Output: Income = Savings (IS) Curve

A

**When income = planned expenditure: **

(S - I) = (G - T) + (X - M)

Increase in income increases savings more than investment → (S - I) is an increasing function of income

Increase in income decreases fiscal deficit, increases imports → (G - T) + (X - M) is a decreasing function of income.

Aggregate Output: IS Curve: Increase in real interest rate

A

When income = planned expenditure

(S- I) = (G - T) + (X - M)

Increase in real interest rate, holding (G - T) + (X - M) and (S - I) constant:

  • Investment decreases
  • Savings must also decrease
  • Decrease in savings must result from decrease in income

Q

Aggregate Output: Equilibrium in the Money Market

A

Real money supply (M/P)

Money demand = f (real rates, income)

M/P = MD (r,Y)

Real rates up → quantity demanded down

Income up → quantity demanded up

Higher real interest rates → higher income

Q

Aggregate Output: Aggregate Supply

A

In the very short run: Aggregate supply does not change (input quantities are fixed)

In the short run: input prices are fixed so businesses expand real output when (output) price increase

In the long run: Aggregate supply is fixed at full-employment or potential real GDP

Q

Business Cycles: Labor and Capital Utilization

A
  • Firms are slow to hire/lay off employess or increase/decrease physical capital because frequent adustments are costly
  • At the beginning of a contraction, sales fall and both labor and capital are used less intensively
  • At the beginning of an expansion, sales increase and both labor and captital are used more intensively
  • When sales trends persist, firms adust labor and physical capital over time
40
Q

Business Cycles: Housing Sector

A
  • Highly cyclical sector of the economy
  • Activity determined by:
    • Mortgage Rates: Rates Increase, as housing decreases
    • Income / housing costs: When income rises, housing rises
    • Speculation: Home purchases based on expected price increase
    • Demographics: Household formations, geographic shifts in population density.
41
Q

Business Cycles: External Trade Sector

A
  • Imports determined by domestic incomes - depend on domestic business cycle
  • Exports determed by foreign incomes- independent of domestic business cycle
  • Both imports and exports influenced by currency exchange rates
    • Domestic currency appreaciates: Imports Rise, Exports Fall
    • Domestic currency depreciates: Imports Fall, Exports Rise

Q

Business Cycles: Types of Unemployment

A
  • Frictional unemployment results from time it takes employers and employees to find each other
  • Structural emloyment results from long-term changes in the economy that require workers to gain new skills to fill new jobs
  • Cyclical unemployment results from changes in economic growth; = 0 at full employment.
45
Q

Business Cycles: Unemployment Rate

A

To be counted as unemployed, a person ust be available for work and actively looking for work

Labor force consists of those who are employed and those who are unemployed

46
Q

Business Cycles: Unemployment Measures

A
  • Discouraged Workers and Participation Ratio
  • Discouraged workers are those who are avaiable for work but not emplyed or seeking employment; considered not in labor force and not counted as unemolued.
47
Q

Business Cycles: Inflation, Disinflation, and Deflation

A
  • Inflation: Persistent increase in price level over time
  • Inflation rate: Percent increase in price level over a period (usually one year)
  • Disinflation: Decreae in positive inflation rate over time
  • Deflation: Persistent decrease in price level over time; negative inflation rate
  • Hyperinflation: Out-of-control high inflation
48
Q

Business Cycles: Inflation Indexes

A
  • A price index is a weighted average of goods and services prices compared to a base period used as a proxy for the overall or average price level
  • The consumer price index (CPI) measures the cost of a fixed “basket” of goods and services compared to the cost in a base period
49
Q

Business Cycles: Calculating the CPI

A
  • Find the cost of the CPI basket in the base period
  • Find the cost of the CPI basket in the current period
50
Q

Business Cycles: Other Inflation Indexes

A
  • Price index for personal consumption expenditures: Surveys businesses instead of consumers
  • GDP Deflator
  • Producer price index: Crude materials, intermediate goods, finished goods price
51
Q

Business Cycles: Headline and Core Inflation

A
  • Price indexes that include all goods and services measure headline inflation
  • Core inflation refers to prices of all goods excluding food and energy
  • Food and energy prices are subject to large short-term fluctuations that can magnify or mask the true inflation rate.
52
Q

Business Cycles: Limitations of Inflation Measures

A
  • The CPI is widely believed to overstate the true rate of inflation
  • The most significant biases in the CPI data includeL
    • Consumer substitution of lower-priced products for higher-priced products
    • New goods replace older, lower-priced products
    • Price increases due to quality improvments.
53
Q

Business Cycles: Adjustment for CPI Bias

A

CPI is calculated using basket weights from base period (laspeyres index)

A Paasche index uses basket eweights from current period and compares cost to base period

Chained price index reduces bias from substitution (e.g. Fisher index = geometric mean of Laspeyres and Paasche indexes)

54
Q

Business Cycles: Factors that Affect Price Levels

A
  • Cost-push (or wage-push) inflation: increases in wages or other producer input prices decrease short-run aggregate supply, increase price level
  • Demand-pull inflation: Increase in aggregate demand above full employent increases price level
55
Q

Business Cycles: Cost-Push Inflation (SRAS down)

A
56
Q

Business Cycles: Demand-Pull Inflation (AD up)

A
57
Q

Business Cycles: Non-Accelerating Inflation Rate of Unemployment (NAIRU)

A
  • NAIRU is the lowest unemployment rate that will not induce wage-push inflation; also called natural rate of unemployment
  • Likely varies over time and across countries
  • Not necessarily the same as “full employment” or cyclical unemployment = 0 because wage pressure may be in economic segments
58
Q

Business Cycles: Leading Indicators

A

Turning points in these tend to precede business cycle peaks and troughs

59
Q

Business Cycles: Coincident Indicators

A
  • Turning points in these tend to coincide with business cycle peaks and troughs
60
Q

Business Cycles: Lagging Indicators

A
  • Turning points in these tend to follow business cycle peaks and troughs
  • Unemployment rate is a lagging indicator

Q

Monetary/Fiscal Policy: Monetary Policy

A
  • Management of the supply of money and credit
  • Expasionary: increase the money supply, decrease interest rates, increase aggregate demand
  • Contractionary: Decrease the money supply, increase interest rates, slow economic growth and inflation
63
Q

Monetary/Fiscal Policy: Fiscal Policy

A
  • Government decisions on taxing and spending
  • Expansionary: Increase spending and/or decrease taxes; increase the budget deficit, increase aggregate demand
  • Contractionary: Decrease spending and/or increase taxes; decrease the budget deficit, reduce aggregate demand
64
Q

Monetary/Fiscal Policy: Functions of Money

A
  • Medium of exchange
  • Unit of account
  • Store of value

Much more efficient than barter economy

65
Q

Monetary/Fiscal Policy: Definitions of Money

A

Narrow Money (M1 in U.S. and Eurozone)

  • Currency in circulation
  • Checkable deposits
  • Travelers checks

Broad Money (M2 in U.S. and M3 in Eurozone)

  • Savings deposits
  • Time deposits < $100,000
  • Money market mutual funds
66
Q

Monetary/Fiscal Policy: How Banks Create Money

A

In a fractional reserve banking system, a bank is required to hold a fraction of its deposits in reserve; this fraction is the required reserve ratio

Example: Bank 1 receives $1,000 in new reserves- can loan out $800 in RR of 20%

$800 in loans deposited, $640 in new loands…

$640 deposited, 0.8 x 640 = $512 new loands…

  • Potential increase in the money supply is
  • 1/.2 or 5 x $1,000 = $5,000
  • **Maximum deposit expanision multiplier = 5 **
67
Q

Monetary/Fiscal Policy: Demand for Money

A

Transactions demand: Increases with GDP

Precautionary demand: Money held for unforeseen future needs, increases with GDP

Speculative demand: Money held to take advantage of future investment opportunities, smaller when current returns are high, greater when risk is perceived to be high

Supply of money is set by the monetary authority, central bank

68
Q

Monetary/Fiscal Policy: Equilibrium in the Money Market

A
69
Q

Monetary/Fiscal Policy: Fisher Effect

A

Riskless nominal interest rate = real interest rate + expected inflation

There is also uncertainty about future inflation rates and other economic variables, and a risk premium that increases with uncertainty

Riskless nominal interest rate = real riskless rate + expected inflation + risk premium for uncertainty

70
Q

Monetary/Fiscal Policy: Roles of Central Banks

A
  • Issue currency
  • Banker to bansk and governmet
  • Regulate banking and payment systems
  • Lender of last resort
  • Hold gold and foreign currency reserves
  • Conduct monetary policy
71
Q

Monetary/Fiscal Policy: Objectives of Central Banks

A

All central banks have price stability (low inflation rates) as an obective. Many (except U.S. and Japan) have explicit target rates, usually 2% to 3%

Some central banks also attempt to:

  • Maintain full employment
  • Promote economic growth
  • Keep exchange rates stable
  • Keep long-term interest rates moderate
72
Q

Monetary/Fiscal Policy: Expected and Unexpected Inflation

A
  • Expected inflation increases cost of holding money, adds cost of frequently changing advertised prices
  • Additional costs of unexpected inflation:
    • Shifts wealth from lenders to borrowers
    • Less reliable supply/demand information in price changes
      • Incorrect production decisions by firms
      • Less stable business cycle
73
Q

Monetary/Fiscal Policy: Monetary Policy Tools: Policy Rate

A

Policy rate: Interest rate central banks charge for borrowed reserves

  • By raising the policy rate, Fed discourages banks from borrowing reserves; thus, they reduce their lending
  • Decreasing the discount rate tends to increase the amount of lending and the money supply
  • The U.S. Fed sets a target for the fed funds rate, the rate at which banks lend short-term to each other
74
Q

Monetary/Fiscal Policy: Monetary Policy Tools: Open market operations and required reserve ratio

A

Open market operations: Most often used

  • Central bank buys government securities for cash, reserves increase, money supply increases
  • Selling securities decreases money supply

Required reserve ratio: Seldom changed

  • Reducing required reserve percentage increases excess reserves and increases the money supply
  • Increasing required reserve ratio decreases the money supply
75
Q

Monetary/Fiscal Policy: Central Bank Characteristics

A

To be effective, central banks should be:

  • Independent- free from political interference
    • Operation independence: Free to set policy rate
    • Target independence (ECB): Sets inflation target, measures inflations, determines horizon to meet target
    • Not absolute; viewed as degree of independence.
  • Credible: Banks follow through on states intentions and policies
  • Transparent: Bank discloses inflation reports, indicators they use, and how often they use them

A central bank that is independent, credible, and transparent can influence expectationsl policy changes are anticiplated and easier to implement.

76
Q

Monetary/Fiscal Policy: Monetary Policy Transmissions: CB buys securities

A

When a central bank buys securities:

  • Bank reserves increase
  • Interbank lending rates decrease
  • Short-term and long-term lending rates decrease
  • Businesses increase investment
  • Concumers increase house, auto, and durable goods purchases
  • Domestic currency depreciates, exports increase

Overall, aggregate demand increases, increasing real GDP, employment, and inflation

77
Q

Monetary/Fiscal Policy: Monetary Policy Transmissions: Expansionary Policy

A

Expansionary monetary policy affects four things:

  1. Market interest rates fall, less incentive to save
  2. Asset price increase, wealth effect, consumption spending increases
  3. Expectations for economic growth increase, may expect further decreases in interest rates
  4. Domestic currency depreciates, import prices increase, export prices decrease

Overall, aggregate demand increases, increasing real GDP, employment, and inflation

78
Q

Monetary/Fiscal Policy: Central Bank Targets: Interest and Inflation

A
  • Interest rate targeting: Increase money supply growth when interest rates are above targets, decrease money supply growth when interest rates are below target
  • Inflation targeting: Target band for inflation rate (typically 1% to 3%)
    • Increase money suppy growth when inflation is below target band, decrease money supply growth when inflation is above target band
    • Target inflatinn band >0 to prevent deflation
79
Q

Monetary/Fiscal Policy: Central Bank Targets: Exchange Rate

A
  • Exchange rate targeting: Target band for currency exchange rate with developed country
    • Sell domestic currency when above target
    • Buy domestic currency when below target (limited by available foreign reserves)
    • Central bank does not react to domestic economic conditions
    • Result of successful exchange rate targeting is same inflation rate in domestic economy as in targeted developed country.
80
Q

Monetary/Fiscal Policy: The Neutral Interest Rate

A

Neutral interest rate = trend growth rate of real GDP + target inflation rate

Policy rate > neutral rate: Contractionary

Policy rate < neutral rate: Expansionary

81
Q

Monetary/Fiscal Policy: Limitations of Monetary Policy

A
  1. Long-term rate may move oppositely to short term rates because inflation expectations change
  2. If monetary tightening is etreme, expectations of recession may make long-term bonds more attractive, decreasing long-term rates
  3. If demand for money is very elastic, people will hold currency even as money supply increases, referred to as a liquidity trap
  4. Banks may desire to increase capital and not increase lending in response to expansionary monetary policy
  5. Short-term rates cannot be below zero–limits a central bank’s ability to act against deflation

Recently, central banks have employed quantitative easing (QE), buying longer-dated government securities, mortgage securities, and risky bonds

82
Q

Monetary/Fiscal Policy: Fiscal Policy Types

A

Expansionary Fiscal Policy

Increase government spending, decrease taxes, or both–increasing aggregate demand and the budget deficit

Contractionary Fiscal Policy

Decrease government spending, increase taxes, or both–decreasing aggregate demand and budget deficit

83
Q

Monetary/Fiscal Policy: Fiscal Policy perspectives

A
  • Keynesian economists believe discretionary fiscal policy can stabilize the economy, increasing aggregate demand to combat recession and decreasing aggregate demand to combat inflation
  • Monetarists believe that such effects are temporay and that appropriate monetary policy dampen economic cycle
  • Automatic stabilizers (taxes and transfer payment) tend to increase deficitis during recessions and decrease deficits during expansions
84
Q

Monetary/Fiscal Policy: Fiscal Policy Objectives

A

Governments use fiscal policy to:

  1. Influence aggregate demand and economic growth
  2. Redistribute wealth
  3. Affect the allocation of resources to different sectors of the economy
85
Q

Monetary/Fiscal Policy: Fiscal Tools: Spending

A
  1. Transfer payments: Cash payments by government to redistribute wealth
  2. Current spending: Purchases of goods and services
  3. Capital spending: To increase future productivity; on infrastructure, or to support research on and development of new technologies
86
Q

Monetary/Fiscal Policy: Fiscal Tools: Revenue

A

Direct taxes--levied on income or wealth

Takes time to implement

Indirect taxes–levied on goods and services

Quick to implement to raise revenue or promote social goals (e.g. tobacco tax)

87
Q

Monetary/Fiscal Policy: Fiscal Multiplier

A

Note: MPC is Marginal Capacity to consume and is calculated by change in consumption divided by change in income or ^C/^I

88
Q

Monetary/Fiscal Policy: Tax Multiplier

A
  • With MPC = .8, a tax increase of $100 billion will reduce consumption by .8 x 100 = $80 billion
  • The fiscal multiplier effect will, over time, lead to a decrease in consumption spending of 2.27 x $80 billion = $182 billion

The balanced budget multiplier is positive

A $100B increase in spending + a $100 billion increase in taxes ca, over time, increase consumption spending by $227 - $182 = $45B

89
Q

Monetary/Fiscal Policy: Ricardian Equivalence

A
  • If a tax decrease causes taxpayers to increase savings in anticipation of higher future taxes, the resulting descrease in spending will reduce the expansionary impact of a tax cut
  • If the increase in saving (decrease in consumption) just offsets the tax decrease, it is termed Ricardian equivalence
  • An increase in spending funded by issuing debt will have no impact on aggregate demand
90
Q

Monetary/Fiscal Policy: Government Debt

A

If the real interest rate on government dbt is less (greater) than the real rate of growth, debt ratio will decrease (increase) over time

91
Q

Monetary/Fiscal Policy: Budget Deficits - Con

A

Reasons to be concerned about deficits

  • Higher future taxes will decrease GDP growth
  • Government borrowing can drive up interest rates and reduce (crowd out) private investment
  • At some point, debt can become risky, interest rate rises, country may default or expand money supply and cause inflation
92
Q

Monetary/Fiscal Policy: Budget Deficits - Pro

A

Arguments that deficits are not concerning

  • If the deficit is to finance capital investment, future GDP will be higher
  • Deficits don’t matter if Ricardian equivalence holds
  • If the economy is operating below capacity, government borrowing will not displace capital investment
93
Q
