Which curve does a successful supply-side policy shift, and in which direction?

It shifts long-run aggregate supply to the right, and where it lowers firms' costs it shifts short-run aggregate supply to the right as well.

Describe the AD/AS effect of a cut in employers' National Insurance contributions.

It lowers the cost of employing labour, shifting short-run aggregate supply to the right, so the price level falls and real output rises.

State two strengths of supply-side policies.

They allow output to rise without generating inflation, and they tackle the structural causes of unemployment and low productivity rather than only the symptoms.

Questions from this subtopic

Each one with the model answer underneath.

1
Which curve does a successful supply-side policy shift, and in which direction?
Model answer
It shifts long-run aggregate supply to the right, and where it lowers firms' costs it shifts short-run aggregate supply to the right as well.
2
What happens to the price level and real output when long-run aggregate supply shifts right and aggregate demand is unchanged?
Model answer
Real output rises and the price level falls, so the economy grows without inflation.
3
Why are supply-side policies said to improve the trade-off between inflation and unemployment?
Model answer
Greater capacity allows aggregate demand to grow further before bottlenecks appear, so output and employment can be higher at any given rate of inflation.
4
How can a supply-side policy shift aggregate demand as well as aggregate supply?
Model answer
Government spending on training or infrastructure is itself an injection of demand, and a tax cut intended to sharpen incentives also raises disposable income and spending.
5
Describe the AD/AS effect of a cut in employers' National Insurance contributions.
Model answer
It lowers the cost of employing labour, shifting short-run aggregate supply to the right, so the price level falls and real output rises.
6
State two strengths of supply-side policies.
Model answer
They allow output to rise without generating inflation, and they tackle the structural causes of unemployment and low productivity rather than only the symptoms.
