CHAPTER 11: Fiscal Policy
1. Keynesian Theory of Macroeconomic Instability
Key Insight: The Keynesian theory advocates for government intervention in cases of macroeconomic instability.
Foundation of Theory:
Insufficient aggregate demand leads to unemployment.
Excessive aggregate demand results in inflation.
Government's Role:
When the market fails to adjust imbalances, intervention is required to manage aggregate demand.
Government must increase aggregate demand during downturns and decrease it during booms.
2. Recent Presidential Approaches to Fiscal Policy
President Obama:
Adopted Keynesian policies to boost aggregate demand during the recession.
Developed spending and tax cut packages before taking office.
President Trump:
Implemented Keynesian strategies to foster economic growth, despite not facing a recession initially.
President Biden:
Followed similar Keynesian approaches in his fiscal policies.
3. Major Questions Regarding Fiscal Policy
Can government actions ensure full employment?
Which policies effectively combat inflation?
What are the inherent risks of government intervention?
4. Taxes and Spending
Constitutional Basis:
Article I grants Congress the authority to levy taxes and spend for public welfare.
Historical Context:
Prior to 1915, federal government taxes and expenditures were minimal.
Example: 1902 federal spending = $650 million with fewer than 350,000 federal employees.
Modern Expenditures:
Today, over 3 million employees and about $6 trillion in spending annually.
4.1 Government Revenue
Tax Collections:
Post-1913 (Sixteenth Amendment) allowed income tax, expanding revenue sources.
Current annual federal tax revenue: nearly $5 trillion.
Individual income taxes are the largest source (approx. half); followed by Social Security payroll taxes and corporate income taxes.
4.2 Government Expenditure
Shifts in Expenditure:
Historical: fed expenditures mirrored limited revenue.
Current scenario: spending exceeds revenue, necessitating borrowing.
Types of Spending:
Government Purchases: Involves real goods/services and is part of aggregate demand (e.g., defense, highways).
Transfer Payments: Income distribution (e.g., Social Security) that only affects aggregate demand when recipients spend it.
Less than half of federal spending is on goods and services; remainder is transfers or interest on debt.
5. Fiscal Policy Defined
Fiscal Policy Tools:
Government can influence aggregate demand through:
Adjusting purchases of goods and services.
Modifying tax rates.
Changing income transfer levels.
Macro Perspective:
The federal budget is a tool for shifting aggregate demand and altering macroeconomic outcomes.
6. Fiscal Stimulus
6.1 Premise and Policy Goals
Goal: Shift the AD curve to improve short-run macro equilibrium, particularly in recession scenarios.
Example Imbalance:
Macro equilibrium at $5.6 trillion vs. full-employment GDP at $6 trillion.
Resulting GDP gap of $400 billion indicates recessionary conditions.
6.2 Keynesian Strategy for Recovery
AD Adjustment: Rightward Shift
Increase government purchases or reduce taxes to stimulate spending.
Strategic questions:
How much to shift AD?
How to induce the desired shift?
6.3 AD Shortfall Analysis
GDP Gap Insight:
Addressing an initial $400 billion gap via AD shift may not restore full employment due to other market constraints.
Price Level Effects:
Shift of AD raises both output and price levels, thus creating challenges in reaching full employment targets.
6.4 Naïve Keynesian Consideration
Assumption of Constant Prices:
A horizontal AS curve would simplify achieving full employment without price impacts, but this scenario is rare.
Real-world function shows a need for adjustment beyond simple GDP shifts.
6.5 AD Shortfall Calculations
Required Fiscal Stimulus:
Strategy involves increasing aggregate demand beyond mere GDP shortfalls to account for price level changes.
Example: AD needs to reach $6.4 trillion for full employment.
7. Adjusting Aggregate Demand through Government Spending
7.1 Effective Government Spending
Impact: Government spending directly shifts AD and is pivotal for closing GDP gaps.
Multiplier Effect:
Increased spending not only adds direct demand but also stimulates further consumption as income circulates.
Formula:
Total change in spending = Multiplier × New spending injection.
7.2 Government Spending Example
Increasing AD by $800 billion through direct government spending exhibits ripple effects through the economy via multipliers, ultimately impacting total demand positively and rapidly.
8. Tax Cuts as a Tool for Economic Stimulation
Impact of Tax Cuts:
Tax cuts lead to increased disposable incomes indirectly boosting consumption directly and employing multiplier effects.
For example: A $200 billion tax cut might yield $150 billion in immediate consumption.
8.1 Multiplier Effects of Tax Cuts
Transaction Cycle:
Initial consumption vlaues determined by the MPC's effect on consumer behavior stemming from tax reductions.
Cumulative change in demand calculated similarly to spending injections through the multiplier.
9. Other Vehicles for Fiscal Policy: Transfers and Budget Adjustments
9.1 Transfer Payments
Increasing transfer payments can also boost consumption among the economically vulnerable groups leading to larger aggregate demand shifts via the multiplier.
9.2 Fiscal Restraint Approaches
In conditions of overheating, fiscal policy may require reducing AD via spending cuts or tax hikes to control inflation.
9.3 Budget Cuts
Budget cuts initiate a chain of decreased consumer spending due to reduced earnings; the multiplicative effect necessitates estimating desired fiscal restraint rigorously.
10. Practical Considerations in Implementing Fiscal Policy
10.1 Crowding Out Phenomenon
Fiscal policy can inadvertently reduce private sector activities through competition for financial resources, thereby offsetting intended fiscal stimulus.
