04 Aggregate Supply Flashcards
How does a rise in price affect aggregate supply?
An expansion of aggregate supply.
How does a fall in price affect aggregate supply?
A contraction of aggregate supply.
Why is the SRAS curve upward slopping?
Because higher prices for goods and services make output more profitable and enable businesses to expand their production by hiring less productive labour and other resources.
What are shifts in SRAS caused by?
A change in the costs of production.
How will firms expand their production when there is a rise in the price level?
- Firms will need to employ more factors of production (such as labour)
- A rise in price level will incentivise firms to increase their output (production), as firms are likely to face higher costs through employing less productive FoP
What are the factors that cause a shift in SRAS?
Employment costs: - Wages, NI, productivity Costs of other inputs: - Costs of raw materials (commodities), exchange rates (SPICED/WPIDEC) Impact of government: - Corporation tax - Pollution permits
What impact will a rise in costs of production, and a leftward shift in SRAS have?
- Fall in economic growth
- Rise in inflation
- Fall in economic growth means firms require fewer workers (labour is a derived demand for output)
What impact will a rise in the national minimum wage have on SRAS?
It will shift to the left.
What does LRAS (long-run aggregate supply) show?
The output that an economy can produce when using all its factors of production.
Why is LRAS perfectly inelastic?
There is no relation between price level and real GDP.
What does an outward shift of LRAS show?
A rise in productive potential.
The level of the LRAS is caused by a change in either…
quantity or quality of the factors of production.
Fall in quantity/quality =
Fall in LRAS.
Rise in quantity/quality =
Rise in LRAS.
Explain how an economy can increase its LRAS.
The productivity of labour and capital increases - there is a rise in output per person employed or increased efficiency of technology - or education and training.
Define a negative output gap.
When the actual output gap of an economy is less than potential output, i.e., productively inefficiency PPF.
Define aggregate supply.
All planned production by firms in the economy added together (i.e., the sum of all the industry supply curves in the economy) and it shows how much output UK forms will supply at each price level.
Why does aggregate supply slope rightwards?
Because:
- There is an incentive to produce more at a higher price level
- As the economy works towards ‘full capacity’ costs will rise, meaning that the price level must rise
