What Are Examples of Supply-Side Policy?
Examples of supply-side policy include training, infrastructure and technological support. Learn how each can raise productivity and productive capacity.
Examples of supply-side policy include training workers, improving infrastructure and supporting technological improvement. Each aims to help an economy produce more efficiently or increase the amount it can produce.
This answer covers Cambridge International AS Level Economics 9708, 5.4 Supply-side policy: its meaning and effect on long-run aggregate supply (5.4.1), its objectives (5.4.2), examples of its tools (5.4.3), and its possible effects on real output, the price level and employment (5.4.4).
How do the examples work?
- Training helps workers gain skills. A more skilled workforce may produce more output from the same resources, raising productivity.
- Infrastructure development, such as improving transport or electricity networks, can help firms move goods and operate more reliably. This can increase the economy’s productive capacity — the maximum output it can produce with its available resources.
- Support for technological improvement can help firms adopt better equipment or methods. For example, support for research or new technology may allow firms to produce more with the same inputs.
Suppose improved roads let firms deliver materials faster and spend less time waiting for supplies. They may be able to produce more at a lower cost. This shows how infrastructure can raise productivity rather than merely add to government spending.
In an aggregate demand and aggregate supply model, a successful supply-side policy shifts the long-run aggregate supply curve to the right. This represents greater productive capacity. If aggregate demand stays the same, real output may rise while the price level falls; higher output may also support employment. The effects are not guaranteed, though: training takes time, and infrastructure must meet firms’ needs to make a difference.
Common exam mistake: Do not describe any policy that increases spending as supply-side policy. The key question is whether it improves productivity or productive capacity. For example, building a useful transport link may do this; simply increasing government spending does not necessarily do so.
