Demand Management: Fiscal & Monetary Policy
Demand Management and Fiscal Policy
Fiscal Policy
Definition: Fiscal policy is the government's policies on expenditure and taxation.- Fiscal matters relate to government revenue and expenditure.
Government spending includes all levels: federal, regional, and local.
Types of Government Spending:- Capital Expenditure: Adds to the capital stock (e.g., highways, schools).
Current Expenditure: Ongoing spending (e.g., public employees' wages, textbooks).
Transfer Payments: Benefits paid without goods/services produced in return (e.g., unemployment benefits, pensions).
Expansionary Fiscal Policy: Increases AD (Aggregate Demand).
Contractionary Fiscal Policy: Decreases AD.
Aims of Fiscal Policy
Maintain low, stable inflation.
Achieve low unemployment.
Ensure a stable economic environment for long-term growth.
Reduce business cycle fluctuations.
Promote equitable income distribution.
Achieve external balance between export revenue and import expenditure.
Expansionary Fiscal Policy
Keynesian Approach: Government intervention is necessary to control the economy.
Fiscal Measures:- Lower income taxes: increases disposable income, boosting consumption and AD.
Lower corporate taxes: increases after-tax profits for firms to invest, boosting AD.
Government investment projects: improves public services, boosting AD.
Effects of Expansionary Fiscal Policy
AD increases (AD1 to AD2) due to increases in (C, I, G, Xn).
Inflationary pressure: average price level rises (PL1 to PL2).
Real output increases (Y1 to Y2): national income increases, economic growth occurs, unemployment likely decreases.
Trade-off: lower unemployment vs. higher inflation.
Effectiveness of Expansionary Fiscal Policy
Historical evidence: Countries using demand management recovered faster from recessions (e.g., Great Depression, 2008 Recession).
Targeted spending: Governments can direct funds to specific sectors and provide targeted tax cuts.
Example: The American Recovery and Reinvestment Act.
Contractionary Fiscal Policy
Used to decrease AD when there's an inflationary gap.
Methods:- Decrease government spending.
Increase personal income taxes.
Increase business taxes.
A combination of the above.
Strengths of Fiscal Policy
Pulling the economy out of deep recessions (e.g., Great Depression, 2008 Recession).
Targeting specific sectors (e.g., education, healthcare).
Direct impact on AD.
Dealing with rapid inflation via contractionary policy.
Affecting potential output by creating a stable environment and investing in human/physical capital, encouraging firm investment.
Automatic Stabilizers (HL ONLY):- Progressive income taxes: taxes fall with income.
Unemployment benefits: benefits increase with unemployment.
Constraints of Fiscal Policy
Time Lags: Policy changes and implementation take time, impacting responsiveness.
Political Pressure: Political considerations may override economic needs.
Sustainable Debt: Deficits for expansionary policy can lead to unsustainable national debt.
Effect on Net Exports: Increased inflation may reduce export attractiveness and increase imports.
Crowding-Out Effect: Government borrowing increases interest rates, reducing private investment. The increase in G (government spending) is offset by a fall in I (investment).
Inability to Achieve Specific Targets: Difficult to precisely adjust policy for specific targets. Predicting accurate outcomes is nearly impossible.
Sustainable Government (National) Debt
Budget Deficit: Government expenditure exceeds tax revenue.
Budget Surplus: Tax revenue exceeds government expenditure.
Government Debt: Total money owed to creditors (domestic & foreign), accumulated from budget deficits.
Governments borrow via bonds or financial institutions.
Debt is often expressed as a percentage of GDP.
Costs of High Government (National) Debt
Short-term benefits: deficit spending can drive economic growth.
Long-term Costs:- Debt servicing: payments on principle and interest.
Increased debt service costs.
Crowding out of private investments (increased spending leading to increased borrowing).
Spending cuts in other areas to repay loans.
Higher taxes to maintain benefits/services (deflationary fiscal policy).
Decreased ability to respond to emergencies by borrowing.
The Multiplier Effect (HL ONLY)
Change in AD component leads to a multiplied effect on real GDP.
Related to leakages and injections in the circular flow of income model.
Example: Government spends 100 million on infrastructure; money is paid for labor, capital, raw materials, etc. Recipients then pay taxes, save, import, and spend the rest on domestic goods/services.
Marginal Propensities (HL ONLY)
Marginal Propensity to Consume (MPC): Fraction of additional income spent on domestic goods/services.
Marginal Propensity to Save (MPS): Fraction of additional income saved.
Marginal Rate of Taxation (MRT): Fraction of additional income taxed.
Marginal Propensity to Import (MPM): Fraction of additional income spent on imports.
Calculating the Multiplier (HL ONLY)
The multiplier effect continues as money is re-spent through the circular flow.
In the example, with 20\% taxes, 10\% savings, and 10\% imports, 60\% is spent on domestic goods/services.
Multiplier can be calculated using MPS, MPM, MRT, MPW, or MPC.
Example Calculation:
*Given: MPC = 0.75
The multiplier = \frac{1}{(1-0.75)} = \frac{1}{0.25} = 4
*Therefore, an investment of 50,000 would result in a final increase in national income of 4 \times 50,000 = 200,000.
Demand Management and Monetary Policy
Monetary Policy
Definition: Policies governing money supply and interest rates.
Expansionary Monetary Policy: Increases AD.
Contractionary Monetary Policy: Decreases AD.
Interest Rate: Price of borrowing money.- Various rates exist (mortgage, credit card).
Set by for-profit agencies, regulated by the government, and influenced by the central bank.
Base (Discount or Prime) Rate: Interest rate set by the central bank.
Central banks control money supply and are usually independent for stability.
Aims of Monetary Policy
Maintain low, stable inflation (often targeting 2%).
Achieve low unemployment.
Ensure a stable economic environment for long-term growth.
Reduce business cycle fluctuations.
Achieve external balance between export revenue and import expenditure.
Expansionary (Loose) Monetary Policy
Changes in the base interest rate affect other rates.
Lower rates reduce borrowing costs, increasing consumption/investment and closing recessionary gaps.
Increased money supply also lowers interest rates.
Leads to increased AD, real output (Y1 to Y2), and average price level (PL1 to PL2).
Likely decreases unemployment, but trade-off with higher inflation remains.
Contractionary (Tight) Monetary Policy
Used to close an inflationary gap by reducing AD.
Higher interest rates increase borrowing costs, reducing consumption and investment.
Strengths of Monetary Policy
Quick to implement.
No political intervention (usually).
No

Weaknesses of Monetary Policy
Time Lags: Takes time for changes to have impact.
Blunt Instrument: Changes affect the whole economy.
Limited During Liquidity Traps: When rates are near zero, it could be ineffective.
May Conflict with Fiscal Policy: Coordination is critical.
Quantitative Easing (QE)
Central bank purchases assets to increase money supply and lower interest rates.
Effective when interest rates are near zero.
Aimed to encourage bank lending and investment.
Exchange Rate Policies
Exchange Rate Systems:
Fixed: Rate is set and maintained by the government.
Floating: Rate is determined by market forces.
Managed Float: Government intervenes occasionally.
How Central Banks Influence Exchange Rates
Buying/Selling Currency: Increases/decreases supply.

Imposing Capital Controls: Limits foreign exchange transactions.
Appreciated Currency
Exports Expensive, Imports Cheaper:-
