👉 Nudge Theory
Definition: A nudge gently pushes people towards better choices WITHOUT removing freedom of choice.
Choice architecture
The way choices are presented — the order, the default, the labelling — affects what people choose. The person who designs these options is called a choice architect.
- Default options — making the desired choice the automatic one (e.g. organ donation opt-out)
- Simplification — making forms shorter or instructions clearer
- Social norms — telling people '9 out of 10 of your neighbours pay taxes on time'
- Salience — making important information more visible (e.g. calorie counts on menus)
💡 Real-World Nudge Examples
- Pension auto-enrolment — employees are automatically enrolled in pension schemes (can opt out). Participation jumps from ~50% to ~90%
- Smaller plates in cafeterias — people take less food, reducing waste
- Flies in urinals — a target to aim at reduces cleaning costs by 80%
- Plain cigarette packaging — removing brand appeal makes smoking less attractive
- Traffic light food labelling — red/amber/green makes healthier options obvious
Nudge vs traditional policies
- Tax/subsidy → changes the PRICE of a choice (traditional economics)
- Regulation/ban → REMOVES a choice (command approach)
- Nudge → changes the CONTEXT of a choice without removing options or changing prices
In exam evaluation questions, nudge theory provides excellent 'counter-argument' material. If asked 'Should governments tax sugary drinks?', you can argue that nudges (like calorie labelling) might be less distortionary.

⚖️ Evaluating Nudge Theory
Advantages
- Low cost to implement compared to taxes or subsidies
- Preserves freedom of choice (people can still choose differently)
- Can be very effective (pension enrolment jumped from 50% to 90%)
- Avoids the negative side effects of bans or taxes
Disadvantages
- Paternalism — who decides what the 'right' choice is?
- Limited effectiveness — nudges may not be strong enough for serious issues (e.g. addiction)
- Manipulation — firms can use nudges to exploit consumers (dark patterns)
- Ethical concerns — is it right for governments to 'manipulate' citizens, even for their own good?
