Behavioural Economics Flashcards
Traditional economics assumes (3)
• Rational consumers: wish to maximise utility from consumption by spending income optimally
• Firms: wish to maximise profits
• Government: wish to improve social and economic welfare of it’s citizens
Behavioural economics
Insights into human behaviour to explain economic decision making
Bounded rationality
People aren’t rational when making complex decisions they opt to satisfy utility
Default bias in choices
Repetition of purchases/choices often become automatic because these choices don’t involve cognitive effort
(eg choice of razor, cereal, sandwich, political party)
Choices influenced by social norms
Social norms become accepted by the majority of a given community of people (eg wearing a seat belt and buying a round of drinks)
Availability bias
When people judge the likelihood of an event and it’s frequency if it’s occurrence by the ease with which examples and instances come easily to mind
(eg recent plane crash=more people get the train and jaws increased fear of shark attacks)
Anchoring bias
Human tendency to rely too much if the initial piece of info given (anchor), people use this unrelated info when making subsequent choices
Framing
Putting a question in a different way often generates a new response by changing the comparison it’s viewed in
For example altering what info is given, 90% fat free vs 10% fat
Altruism and fairness
• Altruism refers to our concern for the welfare of others
• Altruistic behaviour comes from people’s perception of fairness
Loss aversion
When we emphasise losses more than potential gains, losses can be twice as painful as similar gain
Choice architecture
Describes how the decisions we make are affected by the layout/ sequence and range of choices that are available
Choice architecture examples (4)
• Nudges
• Restricted choice
• Framing
• Default choice
Are nudges effective? (3)
• Might be useful in changing minor behaviours
• Unlikely to to address deep rooted issues
• Interventions such as taxes, subsidies and regulation may be as effective
Richard Thaler Pensions
Suggested a pension plan where people contribute to their pensions only when their incomes increase so they never see a result ruin in their disposable income
Why do people give in to bounded rationality? (4)
