What is rational behaviour?
Acting in pursuit of self-interest to maximise their own utility by making logical, sensible decisions.
What is utility?
Enjoyment/satisfaction derived from consumption of a good or service.
What is marginal utility?
Enjoyment/satisfaction from consuming one more unit.
When is total utility maximised?
When marginal utility = 0
What is diminishing marginal utility?
The marginal utility obtained from consuming a good or service falls as consumption increases.
What is asymmetric information?
When one party to a transaction possesses less information that is relevant to the exchange.
What is adverse selection?
When the wrong product gets chosen.
What is bounded rationality?
When your ability to behave rationally is restricted by the limited information you have or your ability to understand the information, or the amount of time you have to make a decision. You want to behave rationally but these 3 things inhibit your ability to do so, instead you satisfice.
Eg. takeaway, burger at a sports fixture, order the wrong thing a menu
What is bounded self-control?
This is when you know what the right choice to make is but you lack the will power to make the right decision.
Eg. abandoning diet plans, promising to drink less but then not
What is anchoring?
The tendency to rely too much on the first piece of information offered- using an initial piece of information when making judgements. People may not make the right decision because of the irrationality of using the anchor.
Eg. quotes for a new kitchen/extension
What is loss aversion?
People are more sensitive and responsive to losses than gains. People may make a safe decision instead of the best decision to avoid risk.
Eg. choosing the same thing at a restaurant, bring a bag to the supermarket to avoid having to pay for one, buying/selling stocks
What is thinking fast?
Intuitive, instinctive and automatic thinking
What is thinking slow?
Concentrating, taking mental effort
Examples of thinking fast
Buying a coffee, lunch order, putting the binds out
Examples of thinking slow
holidays, universities, marriage
What are heuristics?
Mental shortcuts people use in their day to day lives to simplify complex decisions aka rules of thumbs.
Examples of heuristics
drinking at the weekend, buying the cheapest option, choosing the most popular brand
Are heuristics useful?
They can save time and effort
What’s the problem with heuristics?
Lead to sub-optimal decisions.
Eg. if you always buy the cheapest option you may not be satisfied
What is availability/recency bias?
This occurs when individuals makes judgements about the likelihood of future events according to how easy it is to recall examples of similar events.
People put too much probability of an event happening because they can vividly remember it happening.
eg. lottery winners, lane travel after a recent crash, polls of best/favourite movies/actors/footballers
What is scarcity bias?
The more difficult it is to acquire an item, the more we value it, so we want it more resulting in mental impulses to buy.
EG. limited time offers, high demand, going quickly, 1 remaining.
What is cognitive bias?
A mistake in reasoning or other mental thought process occurring as a result of using rules of thumb or holding on to preferences and belief regarding contrary information.
What is status quo bias?
People prefer things to remain the same and change as little as possible as changing the status quo is likely to make things worse. ie. stick to what you know
What is memory bias?
This influences what and how easily one remembers- people process accurate memories with significant emotional events eg fish and chips by the seaside and bad memories with certain products/places.
