1 - introduction (part 1) Flashcards
what is experimental economics - used to study human behaviour
- uses controlled experiments, where researchers create decision environments and study behaviour
- uses labs
- isolates causal effects and tests economic theories in controlled environments
what is behaviour economics
- combines insights from psychology and economics to understand how individuals make decisions in real world situations
- uses more realistic psychology than standard econ to explain behaviour
what is the difference between experimental economics and research that uses observational data
experimental
- data is collected from created/controlled environments
observational
- data is collected from real-world, naturally occuring
what are pros and cons of experimental research
- pro = controlled so can generate a causal effect, specifically designed to answer the research question
- random assignment of subjects to treatment = causal when no systematic differences
- replicable - easily repeated
- con = not real-world situation
what does behavioural economics attempt to do
improve the psychological realism, predictive power and policy application of foundations of economic theory
what is orthodox economics
- is the traditional standard economics approach
- emphasises rational decision making
- assumes that people make decisions based on self interest and perfect information
expain what the basic assumption of orthodox economics is
constrained maximisers
- they choose the option that maximises an objective function that captures their objectives
- from what they can choose, they choose the option that maximises their utility
what are the 2 different interpretations of utility maximisation?
maximising…
* utility as pleasure
* utility as measure of preference satisfaction
what are the formulations used:
how does orthodox econ use utility in
risk/uncertainty
time
- risk uncertainty = maximise expected utility
- time = maximise exponentially discounted utility
what are the general assumptions of orthodox maximisation
- there is a function that captures individuals objectives and can be evaluated for each option
- individuals maximise the function
what are the 3 ways that behavioural economics tries to improve psychological assumptions embedded in orthodox economics
- what ways can we pursue more psychological realism assumptions
- maximising something else
- maximising but imperfectly - makes errors
- not maximising at all
- maximising something else
how does this improve standard econ?
- making a more realistic form of preferences
- maximising with error
- economic behaviour may be as a result of people making errors
- or people allowing for errors they expect other people to make
- BE tries to be more realistic by allowing for people making/anticipating errors
how does BE try to be more realistic than orthodox economics
- not maximising
- maybe individuals find an option that is ‘good enough’ dont strive to maximise
- maybe individuals evaluate options in other ways than just by consequences (like orthodox)
- maybe individuals objectives are not really formed until they act on them - orthodox suggests that preferences dont depend on the task just the agent
