Fundamentals of Economics - Fiscal and Monetary Policy Review

Economic Policy Overview

• Economic Policy is divided into two primary categories based on the governing body and the tools utilized:

  • Fiscal Policy: Refers to the government’s policies regarding spending and taxing actions to influence the economy.

  • Monetary Policy: Refers to the behavior of the Central Bank concerning the nation's money supply and interest rates.

Fiscal Policy Fundamentals

• Definition: The manipulation of government spending ($G$) and taxes ($T$) by the government to affect a country’s macroeconomic performance.

• Objectives of Fiscal Policy:

  • Price Stability: In an open market, prices are driven by supply and demand. Severe fluctuations put financial stability at risk; therefore, governments work to maintain stable price levels.

  • Full Employment: Unemployment leads to greater scarcity because resources are underutilized, resulting in lower production. Policies aim to achieve full employment to mitigate scarcity.

  • Economic Growth: Fiscal tools are employed to promote strong and sustainable growth in the economy.

• Categories of Fiscal Policy:

  • Discretionary Fiscal Policy: Deliberate, active changes made by the government to spending and taxing levels.

  • Automatic Stabilizers: These are inherent policies that fluctuate without new legislation, such as transfer payments. Examples include:

    • Unemployment compensation.

    • Social security benefits.

    • Welfare payments.

    • Subsidies.

Types of Fiscal Policy and Budgetary Impact

• Expansionary Fiscal Policy:

  • Purpose: To stimulate the economy or pull it out of a recession, often used during periods of high cyclical unemployment.

  • Methods: Increasing government spending ($\uparrow G$), decreasing taxes ($\downarrow T$), or a combination of both.

  • Impact on Aggregate Demand (AD): These actions shift the AD curve to the right.

  • Budget Deficit: Occurs if government spending exceed tax revenue (G > T). This must be financed through domestic or foreign borrowing. A primary concern is that these debts may burden future generations who must pay higher taxes to repay current debt.

• Contractionary Fiscal Policy:

  • Purpose: To slow down the economy during periods of high inflation, specifically to reduce Demand-Pull Inflation (where growing demand meets insufficient supply, driving prices up).

  • Methods: Decreasing government spending ($\downarrow G$), increasing taxes ($\uparrow T$), or a combination.

  • Impact on AD: These actions shift the AD curve to the left.

  • Budget Surplus: Occurs when tax revenue exceeds government spending (G < T). This is considered a prudent strategy as the government avoids debt and spends within its means.

Strategic Policy Options

• Large vs. Small Government Spending:

  • If current government spending is already too large or inefficient, a tax cut ($\downarrow T$) is preferred during a recession to avoid wastage on unnecessary projects.

  • If government spending is too small and there are unmet social or infrastructure needs, an increase in spending ($\uparrow G$) is recommended. Unlike tax cuts, which allow citizens to spend as they wish, government spending allows the state to direct resources to specific needs.

• Direct vs. Indirect Effects:

  • Changes in taxes or money supply affect AD indirectly through the spending decisions of firms and households.

  • Changes in government purchases of goods and services shift the AD curve directly.

The Multiplier Effect and Mathematical Calculations

• The Multiplier Effect: The additional shift in aggregate demand that results when expansionary fiscal policy increases income and thereby increases consumer spending. Each ringgit spent by the government can raise AD by more than one ringgit.

• Marginal Propensity to Consume (MPC): The fraction of extra income that a household consumes rather than saves.

• Marginal Propensity to Save (MPS): The fraction of extra income that is saved. Represented as $(1 - MPC)$.

• Spending Multiplier Formula:     $\text{Spending Multiplier} = \frac{1}{1 - MPC}$

• Example Calculation:

  • If $MPC = \frac{3}{4}$, then the Multiplier is $\frac{1}{1 - \frac{3}{4}} = \frac{1}{\frac{1}{4}} = 4$.

  • An increase of $RM\,20\,billion$ in government spending generates $RM\,80\,billion$ ($RM\,20\,billion \times 4$) of increased demand.

  • Observation: A larger $MPC$ results in a larger multiplier.

The Crowding-Out Effect

• Definition: An offset in aggregate demand that occurs when expansionary fiscal policy raises the interest rate and consequently reduces investment spending.

• Mechanism of Crowding-Out:

  1. Government spending ($\uparrow G$) increases aggregate demand and income.

  2. Increased income leads households to plan more spending and hold more money, causing money demand ($MD$) to rise.

  3. Increased money demand drives up the equilibrium interest rate ($r$).

  4. Higher interest rates reduce private investment spending, which partly offsets the initial increase in AD (shifting the curve from $AD_2$ back toward $AD_3$).

• Factors Minimizing Crowding-Out:

  • Central Bank Accommodation: If the Central Bank increases the money supply to accommodate the increased spending, interest rates will not rise, preventing crowding-out.

  • Investment Sensitivity: If planned investment is insensitive to interest rate changes (determined by factors other than $r$), it will not fall when rates rise.

Taxation Policy and the Tax Multiplier

• Mechanism: Tax changes lead to changes in disposable income, which shifts aggregate demand.

• Tax Multiplier Formula:     $\text{Tax Multiplier} = 1 - \text{Spending Multiplier}$

  • The tax multiplier is always negative and always one less in magnitude than the spending multiplier.

• Example Calculation ($MPC = 0.8$):

  • Spending Multiplier = $\frac{1}{1 - 0.8} = 5$.

  • Tax Multiplier = $1 - 5 = -4$.

  • A tax cut of $RM\,200\,billion$: $-4 \times -RM\,200\,billion = RM\,800\,billion$ increase in AD.

Comparison of Spending vs. Tax Multipliers

• Scenario: Comparing a $RM\,200\,billion$ increase in $G$ versus a $RM\,200\,billion$ decrease in $T$ ($MPC = 0.8$).

  • $\Delta AD$ from Spending: $5 \times RM\,200\,billion = RM\,1\,000\,billion$ ($RM\,1\,trillion$).

  • $\Delta AD$ from Tax Cut: $-4 \times -RM\,200\,billion = RM\,800\,billion$.

• Key Finding: A tax reduction adds less to AD than an equal increase in government spending because a tax cut injects zero new direct spending into the economy; it only affects disposable income.

• Equivalency Case: To achieve the same $RM\,1\,trillion$ shift as the spending increase, a tax cut of $RM\,250\,billion$ is required ($\frac{RM\,1,000\,billion}{-4} = -RM\,250\,billion$).

Organizational and Time Limitations of Fiscal Policy

1. Recognition Lag: The time required to realize that policy action is needed. This involves assessing the current state of the economy and forecasting the future.

2. Law-making Lag (Administrative Lag): The time taken by the government to pass necessary laws for spending or tax changes. The appropriate policy "medicine" might change by the time the law is approved.

3. Impact Lag (Operational Lag): The time between passing a change and its effects being felt in real output. This depends on the speed of government agencies and the timing of household/business spending changes.

Monetary Policy: Fundamentals and Objectives

• Definition: Manipulation of interest rates and the money supply by the Central Bank to affect macroeconomic performance.

• Objectives of Monetary Policy:

  • Price Stability.

  • Economic Growth.

  • Monetary Stability.

  • Ensuring Sufficient Credit is available.

Operational Tactics of Monetary Policy

• Expansionary (Easy) Monetary Policy:

  • Goal: Stimulate the economy or increase growth. Note: It may lead to inflation.

  • Actions by Bank Negara Malaysia (BNM):

    1. Lowering the reserve ratio.

    2. Lowering the discount rate.

    3. Buying government securities from banks and the public in the open market.

• Contractionary (Tight) Monetary Policy:

  • Goal: Slow down the economy or decrease growth. Note: It may lead to unemployment.

  • Actions by Bank Negara Malaysia (BNM):

    1. Increasing the reserve ratio.

    2. Increasing the discount rate.

    3. Selling government securities to banks and the public in the open market.

Effectiveness and Time Factors of Monetary Policy

• Lags in Monetary Policy:

  • Monetary policy is subject to recognition lag and impact lag (typically 3 to 6 months for full impact on investment/AD/output/prices).

  • Critically, it has no administrative lag because the Central Bank can act very quickly (e.g., daily open market operations).

• Effectiveness: Because it lacks the administrative lag of fiscal policy and can be adjusted precisely every day, monetary policy is viewed as a more effective tool for smoothing economic performance.
