Fiscal Policy

How does the government stabilizes the economy?
Fixed Policy: actions by Congress to stabilize the economy or
Fiscal Policy
·Changes in the expenditures or tax revenues of the federal government
  •   Two tools of fiscal policy
Taxes: government can increase or decrease taxes
Spending: government can increase or decrease spending
·      Fiscal policy is enacted to promote our nation’s economic goals: full employment, price stability, and economic growth
Deficits, Surpluses, and Debt
·   Balanced budget
  •  Revenues = Expenditures
·  Budget deficit
  •  Revenues < Expenditures
·      Budget surplus
  •  Revenues > Expenditures
·      Government Debt
  •  Sum of all deficits – Sum of all surpluses
·      Government must borrow money when it runs on a budget deficit
  •   Government borrows money from
  •   Individuals
  • Corporations
  •  Financial Institutions
  • Foreign Entities or foreign government
Fiscal Policy Two Options
·      Discretionary Fiscal Policy (action)
  •  Expansionary fiscal policy- think deficit
  •  Contractionary fiscal policy- think surplus
·      Non-Discretionary Fiscal Policy (no action)
Three Types of Taxes
·      Progressive Taxes: takes a larger percent of income from high income groups (takes more from rich people)
  •  Ex: current federal income tax system
·      Proportional Taxes (flat rate): takes the same percent of income from all income groups
  •  Ex: 20% flat income tax on all income groups
·      Regressive Taxes: takes a larger percentage from low income groups (takes more from poor people)
  • Ex: sales tax; any consumption taxes
·      Contractionary Fiscal Policy (The BRAKE): laws that reduce inflation, decrease GDP (close a inflationary gap)
  •   Decrease government spending
  •  Tax increases
  •  Combination of the two
·      Expansionary Fiscal Policy (The GAS): laws that reduce unemployment and increase GDP (close a recession gap)
  •  Increase government spending
  •   Decrease taxes on consumers

Classical and Keynesian Economics

Classical:

  • Trickle Down Theory 
  • Help the rich first then everyone else
  • In the long run, the economy will balance @ full employment output
  • The Invisible Hand
Keynesian 
  • AD is the key, not AS
  • In the long run, we are dead
  • Leaks cause recessions

Reasons why prices tend to be "sticky" or inflexible in a downward direction

  1. Menu Cost
  2. Wage Contracts
  3. Minimum Wage
  4. Fear of Price Wars
  5. Morale, Effort-Productivity 
Loanable Funds Market
  • Ig: Gross Private Domestic Investment
  • r: interest rate
  • Sm: supply of money

Multiplier

The Spending Multiplier Effect: An initial change in spending (C, Ig, G, Xn) causes a larger change in aggregate spending or aggregate demand

Multiplier = Change in AD / Change in Spending (C, Ig, G, Xn)

  • Why: expenditures and income flow continuously which sends off a spending increase in the economy
Spending Multiplier = 1 /1-MPC or 1 /MPS

Increase in Spending = +
Decrease in Spending = - 

Tax Multiplier: When government taxes, multiplier works in reverse

  • Why: Now money is leaving the circular flow

Tax Multiplier = -MPC / 1 - MPC or -MPC / MPS

  • Tax Cut = +
  • Now more money in the circular flow

Consumption and Saving

Disposable Income: Income after taxes or net income

DI= Gross Income - Taxes

  • With disposable income, households can either:
    • Consume (Spend Money on goods and services)
    • Save (Not spend money on goods and services)

Consumption

  • Household Spending
  • The ability to consume is controlled by:
    •  The amount of disposable income
    • The propensity to save
  • Do households consume if DI=0?
    • Autonomous Consumption
    • Dissaving
Saving
  • Household NOT spending
  • The ability to save is constrained by:
    • The amount of disposable income
    • The propensity to consume
  • Do households save if DI=0?
    • No
APC and APS
APC= Average Propensity to Consume
APS= Average Propensity to Save

APC + APS = 1
1 - APC = APS
1 - APS = APC
-APS = Dissaving
APC > 1 = Dissaving

MPS and MPS
MPC= Marginal Propensity to Consume
Change in C / Change in DI
  • % every extra dollar earned that is spent
MPS= Marginal Propensity to Save
Change in S / Change in DI
  • % of every extra dollar earned is saved
MPC + MPS = 1
1 - MPC = MPS
1 - MPS = MPC

Determinants of Consumption and Saving
  • Wealth
  • Expectations
  • Household Debt
  • Taxes

AS/AD Model

  • The equilibrium of AS and AD determines current output (GDPr) and the price level (PL)
  • Full Employment: Exists where SRAS and LRAS intersects
  • Inflationary Gap: Output is high and employment is less than NRU
  • Recessionary Gap: Output low and unemployment is more than NRU
