Relationships between objectives and policies

Overview

This study guide explores the critical relationships between government economic objectives and the policies used to achieve them. For GCSE Economics, examiners are not just looking for definitions; they want to see your ability to analyze trade-offs, conflicts, and synergies. When a government uses fiscal or monetary policy to hit one target (like economic growth), it often makes another target (like low inflation) harder to achieve. Understanding these dynamics—and being able to evaluate policy effectiveness using real-world examples and concepts like time lags—is the key to reaching the top mark bands.

The Core Objectives

Governments generally pursue four main macroeconomic objectives simultaneously:

1. Low and Stable Inflation: Typically targeted at around 2% (CPI) in the UK.
2. Low Unemployment: Ensuring as many people as possible who are willing and able to work have jobs.
3. Economic Growth: A steady increase in real GDP, improving living standards.
4. Favourable Balance of Payments: Ensuring the value of exports is roughly balanced with the value of imports.

Policy Instruments

To achieve these objectives, governments and central banks use two main demand-side policies:

Fiscal Policy

Controlled by the government, this involves changes to taxation and government spending.

• Expansionary Fiscal Policy: Lower taxes and/or higher spending. Aimed at boosting aggregate demand (AD), stimulating growth, and reducing unemployment.
• Contractionary Fiscal Policy: Higher taxes and/or lower spending. Aimed at reducing AD to control inflation or reduce a budget deficit.

Monetary Policy

Controlled by the central bank (e.g., the Bank of England), this involves changes to interest rates and the money supply.

• Expansionary Monetary Policy: Lower interest rates. Makes borrowing cheaper, encouraging spending and investment to boost growth.
• Contractionary Monetary Policy: Higher interest rates. Makes borrowing more expensive, reducing spending to cool down inflation.

Policy Conflicts

The central challenge in macroeconomic management is that achieving one objective often conflicts with another. Examiners frequently test your understanding of these conflicts.

1. Economic Growth vs. Low Inflation

This is the most common conflict. If the government uses expansionary policies (e.g., cutting interest rates or increasing spending) to stimulate economic growth, aggregate demand increases. If the economy is close to full capacity, this extra demand pushes up prices, leading to demand-pull inflation.

2. Low Unemployment vs. Low Inflation (The Phillips Curve)

As unemployment falls, the labour market tightens. Firms have to offer higher wages to attract workers. These higher costs are passed on to consumers as higher prices (cost-push inflation). Conversely, if the government uses contractionary policy to reduce inflation, it slows the economy down, leading to job losses and higher unemployment.

3. Economic Growth vs. Balance of Payments

When the economy grows rapidly, consumers have higher incomes. In the UK, a significant portion of this extra income is spent on imported goods. This surge in imports can worsen the current account deficit on the balance of payments.

Policy Synergies

Not all objectives conflict. Sometimes, achieving one objective helps achieve another. This is called a synergy.

1. Economic Growth and Low Unemployment

These two objectives almost always work together. As the economy grows and firms produce more output, they need to hire more workers, thus reducing unemployment.

2. The Role of Supply-Side Policies

Supply-side policies (e.g., education, training, deregulation, infrastructure investment) aim to increase the productive capacity of the economy (shifting aggregate supply to the right).

Examiner Tip: Supply-side policies are the "magic bullet" in evaluation questions because they can achieve multiple objectives simultaneously. By increasing capacity, they allow for economic growth and lower unemployment without causing inflation, resolving the classic demand-side conflicts.

Evaluating Policy Effectiveness

To secure Level 3 and Level 4 marks, you must evaluate how effective these policies are in reality. Key evaluative points include:

• Time Lags: Monetary policy changes (like interest rate cuts) can take 12-24 months to fully impact the economy. Fiscal policy takes time to legislate and implement. By the time a policy takes effect, the economic situation may have changed.
• Ceteris Paribus: The assumption that "all other things remain equal." In reality, external shocks (like a global pandemic or an energy crisis) can undermine domestic policies.
• Magnitude of the Change: A small change in interest rates (e.g., 0.25%) might not be enough to change consumer behaviour if confidence is very low.
• Consumer and Business Confidence: Expansionary policy won't work if people are too scared about the future to spend or invest.
