Inflation, Unemployment, & Stabilization Policies
Budget and Monetary Policy Basics
Budget Surplus
Occurs when government revenues exceed expenditures in a fiscal year.
Simple Budget Balance Calculation
Formula: Budget Balance = Revenues - Expenditures
Role of the Federal Reserve (Fed)
Central bank responsible for managing the U.S. money supply and maintaining financial stability.
Open Market Operations
Buying Treasury bonds/bills: Increases the money supply (expansionary).
Selling Treasury bonds/bills: Decreases the money supply (contractionary).
Monetary Policy and Economic Gaps
Expansionary vs. Contractionary Monetary Policy
Expansionary: Used during recessionary gaps to stimulate growth (lower interest rates, increase money supply).
Contractionary: Used during inflationary gaps to slow growth (raise interest rates, decrease money supply).
Inflationary Gap vs. Recessionary Gap
Inflationary Gap: Economy operates above full employment; leads to inflation.
Recessionary Gap: Economy operates below full employment; leads to unemployment.
Graphs: Be prepared to identify both gaps on Aggregate Demand (AD) and Aggregate Supply (AS) curves.
Economic Models and Theories
Monetary Neutrality
In the long run, changes in the money supply only affect prices, not real output.
Classical Economics (Adam Smith)
Economy is self-correcting with fully flexible prices and wages.
Keynesian Economics
Economy can stay below full employment; supports government intervention.
Quote: "In the long run, we’re all dead."
Short-Run Aggregate Supply (SRAS)
Upward sloping due to sticky wages and prices.
Shifts left when wages/prices adjust upward, reducing profit margins.
Inflation Expectations
Inflation expectations become "built-in" when businesses and workers anticipate ongoing inflation.
Inflation and Its Effects
Inflation Tax
The reduction in the purchasing power of money due to inflation.
Simple Calculation: InflationRate×RealMoneyHoldingsInflation Rate × Real Money HoldingsInflationRate×RealMoneyHoldings.
Effects of High/Low Inflation
High Inflation: Reduces purchasing power, harms savers.
Low Inflation: Stabilizes the economy but may signal weak demand.
Unanticipated Inflation
Benefits borrowers (repay loans with cheaper money).
Hurts lenders and savers.
Phillips Curve
Short-Run Phillips Curve
Shows inverse relationship between inflation and unemployment.
Long-Run Phillips Curve
Vertical at the Non-Accelerating Inflation Rate of Unemployment (NAIRU); inflation expectations adjust.
Shifts in the Phillips Curve
Positive Supply Shock: Shifts curve downward (reduces inflation).
Negative Supply Shock: Shifts curve upward (increases inflation).
Key Economic Concepts
Disinflation
Reduction in the inflation rate.
Can cause higher unemployment in the short term.
Monetarism
Advocates for steady, predictable increases in the money supply to support long-term economic growth.
Quantity Theory of Money
Formula: MV=PQMV = PQMV=PQ (Money Supply × Velocity = Price Level × Output).
Laffer Curve
Demonstrates how tax revenue changes with different tax rates; overtaxing or under-taxing reduces revenue.
Monetary Policy Tools
Discount Rate
The interest rate the Fed charges banks for borrowing.
Federal Funds Rate
The interest rate banks charge each other for overnight loans.
Historical Context
Pre-Great Depression
Classical economics dominated.
Keynesian Economics Emerges
FDR implemented policies influenced by Keynesian thought to address the Great Depression.
"The General Theory of Employment, Interest, and Money" is a key work.
