2.6.4 Conflicts Between Objectives and Policies

Edexcel A-Level Economics (9EC0) | Theme 2.6.4

Specification Coverage: Edexcel unit 2.6.4 - Conflicts Between Objectives and Policies. Students should be able to understand and explain why governments face trade-offs between macroeconomic objectives, analyse key conflicts such as growth versus inflation or equality, interpret the short-run Phillips Curve, and evaluate how policy choices can improve one objective while worsening another.

The Core Problem

Governments face trade-offs when trying to achieve all macroeconomic objectives at the same time.

Improving one objective often worsens another, so policy decisions usually involve prioritisation.

Key Trade-Offs Between Objectives

Trade-Off Explanation
Economic Growth vs. Low Inflation Rapid growth can cause demand-pull inflation as the economy overheats.
Economic Growth vs. Environmental Sustainability Growth often increases pollution, resource depletion, and negative externalities.
Economic Growth vs. Income Equality Growth may benefit capital owners through higher profits, potentially widening inequality.
Economic Growth vs. Current Account Balance Growth raises incomes and increases demand for imports, which can worsen the trade balance.
Low Unemployment vs. Low Inflation The Phillips Curve suggests a short-run trade-off, where lower unemployment may be associated with higher wage inflation.

The Short-Run Phillips Curve

Figure 1: Short-Run Phillips Curve - Trade-Off Between Unemployment and Inflation

What it shows: A short-run inverse relationship between unemployment and inflation.

Reason: When AD rises, output and employment increase, so unemployment falls, but wages and prices are bid up and inflation rises. The reverse is also true.

Limitation: This trade-off only applies in the short run. In the long run, the Phillips Curve is vertical at the natural rate of unemployment (NRU).

Policy Conflicts and Trade-Offs

Policy tools can also create conflicts between short-run and long-run goals.

Policy Conflict Explanation
Monetary Policy: Inflation vs. Growth Raising interest rates to control inflation is contractionary, but it also discourages investment, which can harm long-run supply-side growth.
Fiscal Policy: Short Run vs. Long Run Increased government spending on infrastructure can boost AD in the short run and increase LRAS in the long run. However, it may also cause short-run inflation and budget deficits.
Supply-Side Policy: Efficiency vs. Equity Market-based policies, such as reducing the minimum wage or weakening unions, may improve efficiency and LRAS but can also worsen income inequality.
Environmental Policy vs. Growth Strict environmental regulations can increase costs for firms, reducing short-run output and potentially LRAS in polluting industries, which may conflict with growth objectives.

Exam Preparation

  • Identify and explain the main trade-offs between macroeconomic objectives.
  • Draw and interpret the short-run Phillips Curve and explain the relationship it shows.
  • Analyse specific policy conflicts, such as using high interest rates to cut inflation while harming investment.
  • Evaluate the difficulty of achieving all objectives at once, recognising that policy choices inevitably involve prioritisation.
