| price elasticity/praɪs ɪlæˈstɪsɪti/ | elasticidad precio |
A decision you can investigate
- A tax raises the cost of a popular drink. Sellers and buyers both bear part of the burden.
- The legal taxpayer is not necessarily the person bearing the economic burden.
Build the explanation
- Demand and supply determine market equilibrium; elasticity measures responsiveness.
- A specific tax shifts supply upward by the tax per unit in the standard competitive model.

Use these definitions in the particular context of Demand, supply and policy.
Work through the evidence
- If consumers pay 12 after a tax and producers receive 9, the tax wedge is 3. Compared with an original price of 10, buyers bear 2 and sellers bear 1.
- Consumer payment equals producer receipt plus the tax: 12 = 9 + 3.
Who bears more of this tax compared with the original price?
If consumers pay 12 after a tax and producers receive 9, the tax wedge is 3. Compared with an original price of 10, buyers bear 2 and sellers bear 1. Consumer payment equals producer receipt plus the tax: 12 = 9 + 3.
Which caution belongs to this particular task?
Tax incidence depends on relative elasticities, not who sends the payment to government. Evaluate effects on output, revenue, stakeholders and equity; behavioural assumptions can change responses.
The explanation in this lesson makes a conditional claim; relevant context and evidence still matter.
Evaluate effects on output, revenue, stakeholders and equity; behavioural assumptions can change responses.
