8.2 - Monetary & Fiscal Policy
The key features of fiscal policy
Fiscal policy involves adjustments to government spending and taxation levels to influence the overall economy, including both broad macroeconomic outcomes and specific impacts on firms and individuals.
Types of fiscal policy
Fiscal policy can stimulate or reduce aggregate demand (AD) through two main approaches:
- Reflationary fiscal policy - Also known as expansionary or loose policy, this boosts AD by increasing government spending or reducing taxes, shifting the AD curve to the right. It often results in a budget deficit, where government spending exceeds revenue.
- Deflationary fiscal policy - Also known as contractionary or tight policy, this reduces AD by decreasing government spending or increasing taxes, shifting the AD curve to the left. It often leads to a budget surplus, where government spending is less than revenue.
These approaches are demand-side policies, as they directly affect AD.
When fiscal policy is used and its effects
- Reflationary policy during recessions - Applied in periods of economic downturn or negative output gaps to promote growth and lower unemployment. However, it can raise inflation and worsen the current account of the balance of payments, as higher incomes lead to increased spending on imports.
- Deflationary policy during booms - Used in times of rapid expansion or positive output gaps to slow growth and curb inflation, though it may increase unemployment. It can improve the current account, as lower incomes reduce import spending.
Fiscal policy involves trade-offs, as achieving one objective, such as higher growth, may conflict with others, like low inflation.
Government's fiscal stance
A government's fiscal stance describes the overall direction of its policy:
- Expansionary stance - Reflationary measures that increase AD.
- Contractionary stance - Deflationary measures that decrease AD.
- Neutral stance - Balanced spending and taxation with no net impact on AD.
The main aspects of monetary policy
Monetary policy focuses on managing interest rates, the money supply, and exchange rates to influence economic activity, primarily as a demand-side tool affecting AD.
Tools and types of monetary policy
- Key components - Decisions on interest rates are central, influencing borrowing, saving, spending, and investment. Interest rates also affect the money supply (e.g., high rates reduce loan demand) and exchange rates.
- Contractionary monetary policy - Tight policy reduces AD through high interest rates, restrictions on money supply, and a strong exchange rate.
- Expansionary monetary policy - Loose policy increases AD via low interest rates, relaxed money supply controls, and a weak exchange rate.
As with fiscal policy, trade-offs exist; for instance, boosting growth and employment may increase inflation and deteriorate the current account.
Aims of monetary policy in the UK
The primary goal is price stability, targeting low inflation. In the UK, this means aiming for 2% inflation as measured by the Consumer Price Index (CPI). Secondary aims include supporting economic growth and reducing unemployment.
Stable, credible low inflation prevents high inflation from becoming entrenched and promotes macroeconomic stability by reducing uncertainty, encouraging investment, and aiding future planning.
How interest rates are set and their economic effects
In the UK, interest rates are determined by the Monetary Policy Committee (MPC) of the Bank of England to achieve inflation targets.
Role of the MPC in setting interest rates
- Inflation rate targeting - The MPC sets the official interest rate (Bank Rate or Base Rate) to meet a 2% CPI inflation target. This is symmetric: deviations above 3% or below 1% require the Bank's governor to explain in a letter to the Chancellor.
- Independence and accountability - The Bank operates independently to avoid political interference, but it is accountable; significant target misses trigger public explanations of causes, actions, and timelines for correction.
- Factors considered in decisions - The MPC reviews data like house prices, output gaps, exchange rates for the pound, and changes in average earnings to inform rate changes, balancing price stability with other objectives like growth.
Effects of interest rate changes
Small adjustments in interest rates create ripple effects across the economy, though outcomes can vary.
Increase in interest rates:
- Leads to reduced borrowing and consumer spending.
- Lowers firm investment and decreases confidence.
- Increases saving, reduces exports (due to a stronger pound), and increases imports.
- Overall reduces AD.
Decrease in interest rates:
- Encourages borrowing and spending.
- Boosts investment and confidence.
- Reduces saving, increases exports (via a weaker pound), and decreases imports.
- Overall raises AD.
Additional factors affecting rates:
- The Bank Rate sets a baseline, but market rates (e.g., mortgages, loans) are also affected by factors like banks' borrowing costs from other lenders.
- High UK rates attract 'hot money' inflows, increasing demand for the pound and raising its exchange rate. This makes exports more expensive and imports cheaper, worsening the current account.
- Low rates have the opposite effect, improving the balance of payments by boosting exports and reducing imports.
Limitations including liquidity traps
In pessimistic economic conditions, people may hoard cash rather than spend or invest, making low interest rates ineffective at stimulating AD. This scenario is called a liquidity trap.
The transmission mechanism for interest rate changes
The transmission mechanism illustrates how changes in the official Bank Rate ripple through the economy, ultimately affecting inflation.
Stages of the transmission mechanism
A change in the Bank Rate influences several interconnected areas:
- Market rates - Adjustments affect borrowing and saving rates, influencing consumer and firm behaviour.
- Asset prices - Lower rates often raise prices of houses and shares, as cheaper borrowing encourages purchases.
- Expectations and confidence - Rate cuts can boost optimism, leading to more spending and investment.
- Exchange rate - Lower rates weaken the pound, increasing export demand and raising import prices.
These factors combine to alter domestic demand (internal spending) and external demand (exports/imports), resulting in changes to total demand. This creates domestic inflationary pressure, compounded by import price effects, leading to overall inflation adjustments.
For example, a Bank Rate reduction typically lowers other rates, raises asset prices, improves confidence, weakens the exchange rate, boosts total demand, increases import prices, and exerts upward pressure on inflation.
Time lags in monetary policy effects
The impacts of interest rate changes do not occur immediately due to delays in economic responses.
Reasons for and duration of time lags
- Planning delays - Firms take time to plan and implement investments, often months or years.
- Consumer behaviour - House purchases involve lengthy processes, and fixed-rate mortgage holders feel changes only after their terms end.
Maximum effects are typically seen after about one year for firms and two years for consumers. Consequently, the Bank of England must forecast up to two years ahead when setting rates to account for these lags.
