Individual Economic Decision Making Flashcards

1
Q

Rational behaviour

A

People try to make decisions in their self-interest or to maximise their private benefit. For a household, this would mean attempting to maximise the welfare, satisfaction or utility gained from the goods or services consumed

Q

Diminishing marginal utility

A

As a person increases consumption of a good- while keeping consumption of other products constant- there is a decline in the marginal utility derived from consuming each additional unit of the good

Q

Utility-maximising consumer

A

Consumers attempt the maximise the welfare or utility they gain from the good and services they decided to consume. They do this by comparing the costs and benefits of alternatives. A utility-maximising consumer must choose to consume or demand a good up to a point at which marginal utility = price

Q

How does scarcity restrict consumer choices

A

Limited income, a given set of prices that consumers cannot actively influence, limited time available to consume multiple products- must choose one, the budget constraints

Q

Imperfect information

A

Traditional theories assume that individuals possessing perfect information will make decisions to maximise welfare or correctly choose between alternatives. However economic agents usually don’t have perfect information and make ‘wrong’ decisions and cause market failure

Q

Asymmetric information

A

When one party to a market transaction possesses less information relevant to the exchange than the other. One ways asymmetric info can manifest itself is through adverse selection- sellers have more knowledge than buyers. Can lead to making ‘wrong’ decisions even thought it was rational

Q

Behavioural economic THEORY

A

A method of economic analysis that applies psychological insights into human behaviour to explain how individuals make choices and decisions. Challenges assumptions in traditional economics that economical agents are utility maximisers and rational. Use their insights to design policies or interventions that can encourage, support and enable people to make better choices for themselves or society

Q

Bounded rationality

A

When individuals make decisions, their rationality is limited by three unavoidable constraints: imperfect info, limited mental processing ability,time constraint. In complex choice situations, bounded rationality often leads to satisficing rather than maximising choices

Q

Bounded self-control

A

A rational individual is assumed to have total self-control however behavioural economists believe individuals lack self-control to act in what they see as their self-interest even if they have prefect knowledge

Q

Thinking fast and thinking slow

A

Manly of our economic decisions are taken by our automatic system: decisions are made quickly, and little effort is used to analyse the situation. Bigger and more important decisions tend to be taken by our reflective system: relatively slow, involving careful and logical thought, can be tiring

Q

Bias in decision making

A

Argued that quick decisions that people make when choosing are often heavily biased. This is because decisions are made based on one’s own likes, dislikes and past experiences. ‘Rule of thumbs’ are used to help make sensible decisions based on limited info

Q

Availability (Recency) bias

A

When individuals make judgements about the likelihood of future events according to how easy it is to recall examples of similar events. Often leads to decisions not based on logical reasoning. For example purchasing lottery tickets because you’ve seen winners living lavishly on tv

16
Q

Anchoring

A

The tendency when making decisions to rely too heavily on the first piece of info offered. Individuals use this initial piece of info when making subsequent judgments.

17
Q

Social norms

A

Patterns of behaviour considered acceptable by a society. By unconsciously learning and being influenced from the behaviour of others, social norms are established

18
Q

Altruism

A

When we act to promote someone else’s wellbeing even though we may suffer consequently and aren’t guaranteed to receive any benefit from it: it often results from people’s perceptions of fairness

19
Q

Loss aversion

A

The tendency to prefer avoiding losses to acquiring equivalent gains. Individuals don’t like to lose things that we own and tend to become extremely attached to goods in our possession and feel anxious to give them up even if the chance of losing the good is very low and chance of gain is much higher

20
Q

Choice architecture

A

Choice architecture is a framework setting out different ways in which choices can be presented to consumers, and the impact of the presentation on consumer decision making. This may be used to ‘nudge’ consumers to opt for choices that are deemed to be in their best interest, to achieve a socially desirable outcome.

21
Q

Default choice

A

An option that is selected automatically unless an alternative is specified. Countries that require people to opt out of a certain thing generally have a much high proportional of the population registered for that certain thing than countries that ask people to opt in, because individuals are more likely to choose the ‘default’ option

22
Q

Framing

A

How the context, in which the information is presented, influences the choices people make

23
Q

Mandated choices

A

When people are required to make a decision and not merely go ahead with default position. Most people may choose the recommended settings but still must make an active decision to do so

24
Q

Restricted choice

A

When there is a limited number of options offered so they are not overwhelmed by the complexity of the situation. With too many choices, people may make a poorly thought-out decision or not make one at all.

25
Q

Nudges

A

Factors that encourage people to think and act in particular ways. They attempt to shift group and individual behaviour in ways that comply with desirable social norms but still allow individuals to make a choice

26
Q

Negatives of decision making

A

Too paternalistic?
Very unpredictable and costly
Based on fallacies and biases that people are sensible and can make rational decisions on their own

27
Q

Habitual behaviour

A

A routine of behaviors of certain individuals. You drink coffee every morning at your local shop instead of having it at home. Although this might not be the most rational decision if you’re trying to save money, you will still make it because it’s a habit

28
Q

Herd behaviour

A

A phenomenon in which individuals act collectively as part of a group, often making decisions as a group that they would not make as an individual. They may not be rational

29
Q

Traditional economics

A

Make the assumption that people can gather all info and weigh up the positives and negatives, they argue that everyone is rational and that the rational consumer can take time to make a utility maximising decision. Assumes everyone to be infinitely rational

30
Q

Behavioural economics

A

Disputes rationality and utility maximisation, arguing bounded rationality by time, choice or info, and bounded self control as consumers follow heuristics like rule of thumbs to make satisficing decisions over utility decisions. Explains that emotional, social and psychological factors can influence decision making

31
Q

The 5 choice architectures

A

Framing, Nudges, Default choice, Restricted choice, Mandated choice

32
Q

Priming

A

Our behaviour by cues that work subconsciously and prime us to behave in certain ways —>playing certain types of music in a shopping mall
