About AQA A Level Economics 3.1.2 Individual Economic Decision Making
Individual economic decision making is section 3.1.2 of AQA A Level Economics and is examined on Paper 1. It starts with traditional theory, where consumers are assumed to be rational and maximise utility, and introduces marginal utility and the margin. It then looks at imperfect information and asymmetric information, before covering behavioural economics: bounded rationality, bounded self-control, biases such as rules of thumb, anchoring, availability and social norms, the importance of altruism and perceptions of fairness, and how governments use choice architecture and nudges. Examiners often ask you to compare traditional and behavioural explanations and to evaluate nudge policies against regulation or taxation.
What you need to know
- Consumer behaviour Traditional theory assumes consumers act rationally to maximise utility. Marginal utility is the extra satisfaction from one more unit; the hypothesis of diminishing marginal utility helps explain the downward sloping demand curve.
- Imperfect information Decisions are distorted when information is incomplete, and especially when it is asymmetric, with one party knowing more than the other, as in second-hand car or insurance markets. This links to market failure in 3.1.8.
- Bounded rationality and self-control People have limited time, information and processing ability, so they satisfice rather than maximise. Bounded self-control means people make choices they later regret, such as undersaving or overeating.
- Biases in decision making Rules of thumb (heuristics), anchoring, availability bias and social norms all lead to predictable departures from rational choice. Altruism and perceptions of fairness also affect decisions, as seen in ultimatum-style experiments.
- Behavioural economics and policy Choice architecture shapes how options are presented. Examples include default choices such as opt-out pension enrolment, restricted choice, framing and mandated choices. Nudges influence behaviour without banning options or significantly changing incentives.
- Evaluation Nudges can be cheap and preserve freedom of choice, but effects may be small or short-lived, and some argue they are manipulative. Compare with traditional tools such as taxes, subsidies and regulation.
Common mistakes in 3.1.2 Individual Economic Decision Making
- Defining utility as usefulness. Utility means the satisfaction or welfare gained from consuming a good or service.
- Saying behavioural economics shows people are irrational in random ways. It identifies systematic, predictable biases that can be anticipated by policy makers.
- Describing any government policy as a nudge. A nudge changes the choice architecture without forbidding options or significantly changing financial incentives; a tax is not a nudge.
- Confusing imperfect information with asymmetric information. Asymmetric information is a specific case in which one side of the transaction knows more than the other.
- Giving behavioural terms without applying them. Examiners reward linking a named bias, such as anchoring, to the specific context in the data.
Try three 3.1.2 Individual Economic Decision Making exam-style questions
1. Explain the hypothesis of diminishing marginal utility. (4 marks)
Show the mark scheme answer
Marginal utility is the additional satisfaction from consuming one more unit; as more units are consumed, each extra unit adds less satisfaction; for example a third slice of pizza gives less utility than the first; this helps explain why consumers buy more only at lower prices, giving a downward sloping demand curve.
2. Explain how anchoring can affect a consumer's decision, using an example. (4 marks)
Show the mark scheme answer
Anchoring is relying too heavily on the first piece of information received; later judgements are adjusted from this starting point; for example a shop showing a high original price makes a sale price seem like a bargain; so the consumer may buy even though the sale price is not good value.
3. Evaluate the use of default choices to increase saving for retirement. (15 marks)
Show the mark scheme answer
Explain bounded self-control and inertia lead to undersaving; automatic enrolment with an opt-out uses the default to increase participation; low cost to government and preserves choice; evaluate: people may stay at a low default contribution rate; those on low incomes may opt out; effect depends on the size of the default; may need to be combined with tax incentives; reach a supported judgement.
