Evaluate in IB Economics
Make an appraisal by weighing strengths and limitations against explicit criteria.
What your response needs
Set criteria → analyse benefits → analyse limitations → weigh significance → conditional judgement.
- A clear policy or theory objective
- Benefits and costs with developed mechanisms
- Conditions, evidence, stakeholders and time horizon
- A justified final judgement
A worked economics example
Question: Evaluate the effectiveness of indirect taxation in reducing demerit-good consumption.
An incomplete response: Taxes raise prices, but they are regressive. Overall, they can work.
A more complete response:
An indirect tax raises producers’ costs and shifts supply upwards. The consumer price rises, so quantity demanded decreases along the demand curve. This can reduce consumption and internalise external cost.
Its effect is larger when demand is price elastic and substitutes are available; with inelastic demand, revenue may rise while quantity changes little.
Reformulation can improve effectiveness, while regressivity may require targeted use of revenue.
Therefore, a well-calibrated tiered tax is most effective when combined with information and accessible substitutes.
Common mistakes to avoid
- Giving equal space to points without weighing them
- Making an absolute judgement unsupported by conditions
- Confusing evaluation with criticism only
Try it yourself
Read the question and its mark allocation before deciding how much detail to include. A response structure helps you organise your answer; it is not a script to memorise.
