State the conflict and the conditions under which it arises.
Demand expansion can support growth and employment while adding inflation pressure near capacity. Demand restraint can lower inflation pressure but weaken output and jobs. Faster growth can strain the environment or leave some groups behind; a stronger currency can dampen imported inflation while weakening some export demand. These conflicts are conditional, not permanent laws. Supply improvements and targeted support can sometimes ease them, although they also have costs and take time.
- Objective conflicts
- A conflict arises when improving one objective worsens another. After a cost shock, demand support can protect output and jobs while adding price pressure because it does not remove the original cost increase.
- Conditions matter
- The conflict is stronger when production cannot respond easily. Successful supply improvements can instead raise output while easing price pressure, though they take resources and time; trade-offs are not permanent laws.
Worked example: Restoring output at a higher price level
An economy faces higher imported production costs and rising prices. A demand-support package would restore model output to its earlier level, but raise the price index further. Workers in exposed sectors face job losses.
- Demand support addresses the output loss but does not remove the original input-cost shock.
- Restoring output through demand alone can add price pressure, creating a short-run priority choice.
- A measured response may combine targeted protection with measures addressing costs or capacity; assess timing, funding and who bears the remaining losses.
Watch out for this
Growth and price stability can never improve together.
Favourable supply changes can raise output while easing price pressure. Even demand growth need not cause large inflation pressure when substantial capacity is idle.
Check your understanding
When is a growth-price-stability conflict from demand expansion most likely?
- An effective productivity improvement is the only change.
- The economy is close to binding capacity constraints.
- There are unlimited unemployed resources of every required type.
