2.6.4 Conflicts Between Objectives and Policies
Edexcel A-Level Economics (9EC0) | Theme 2.6.4
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
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.
