Questions from this subtopic
Each one with the model answer underneath.
- 1
What happens to the long-run aggregate supply curve when supply-side policies are successful?
Model answer
The LRAS curve shifts to the right, increasing potential output.
- 2
What are the effects on real GDP and price level when LRAS shifts right due to supply-side policies, ceteris paribus?
Model answer
Real GDP increases and the price level falls.
- 3
How can supply-side policies enable non-inflationary economic growth?
Model answer
By expanding productive capacity alongside aggregate demand, allowing output to increase without creating excess demand and inflation.
- 4
What is a key strength of supply-side policies regarding long-term growth?
Model answer
They can increase the economy's productive potential and trend rate of growth.
- 5
How can supply-side policies help reduce structural unemployment?
Model answer
By improving labour market flexibility and skills matching, helping workers find jobs that suit their abilities.
- 6
How can supply-side policies improve international competitiveness?
Model answer
By reducing costs and increasing productivity, making domestic goods and services more attractive in global markets.
