Describe Classical Economics
Many of the forefathers of economics (i.e. Adam Smith) acknowledged the important role that psychological principles play in human behavior.
It departed from psychology because they wanted a more exact science and also because psychology was just in its early stages (late 19th Century)
What happened during the era of Neoclassical Economics
There was a departure from the young science of psychology in the turn of the 20th century
Describe Neo-Classical Economics
Describe 4 components describing people from a standard economics
People are…
Define Heuristics
Simple Rules of Thumb
Heuristics are influenced by irrelevant info
Decisions are biased (50% of managerial decisions fail, Errors do not equal biases)
Relying on heuristics and biases lead us to…
To make mistakes, because heuristics can be influenced by irrelevant info i.e. decisions are biased. (Biases also cannot be unseen and are likely to be repeated)
Describe the Heuristics and Biases Approach (Amos Tversky, Daniel Kahneman)
It states our world is too complex (too much info, not enough processing powers), people employe heuristics to evaluate info. These rules help us make sense of our complex environment, fast and effortlessly which can lead to why we employ stereotypes.
How is Behavioral Economics different than Standard Economics?
While its similar, behavioral economics is w/ out the assumption that people are rational.
When making a policy, Ariely says we should consider human behavior.
It’s descriptive, not prescriptive. Descriptive models remove the assumption of rationality, is experimental, and tries determine what factors determine human behavior.
Describe the: (Classical Economics) Expected Utility Theory (EUT) and its 4 axioms
Describe Prospect Theory (Kahneman and Tversky)
What are the two phases of the Prospect Theory?
Editing & Evaluation
Describe the Editing + Evaluation Phases of the Prospect Theory
We make a preliminary analysis of the possible prospects to simplify things to help us make a decision
A. Coding (perceiving the prospects by combining probabilities associated with identical outcomes)
B. Combination: Simplifying the prospect by combining probabilities associated w/ identical outcomes
C. Segregation - separating risky vs. safe
D. Simplification - rounding outcomes and probabilities
E. Dominance - searching for dominant alternatives
Evaluation Phases selecting the prospect w/ the (subjective) highest value
Name the 6 behavioral regularities.
Describe the Reflection Effect
Tendency for a mirror image preference btwn positive and negative prospects.
The reflection of prospects around 0 reverses the preferences.
Example problem:
Alternative A: $3000 for sure (80% of people selected this), vs. Alternative B: $4000 for 80%, otherwise.
Mirror image of that situation:
Alternative C: -$3,000 for sure vs. Alternative D -$4,000, 80% ($0 otherwise - 92% of couples chose this).
Describe the Endowment Effect (Richard Thaler)
What are the three basic Heuristics?
Describe Representativeness (Heuristics)
A. Used when making judgements about probability of events
B. Work under the rule the more of an object X is similar to class Y, the more likely is it that the object belongs to the class
C. The problem - similarity doesn’t always predict probability (i.e. toss a coin 6 times and get heads 5 times)
These all lead us to systematic mistakes.
Describe availability (heuristics)
A. Used when making judgements about frequency of events
B. When things are more frequent, we think about them more.
I.e. plane crash, people become scared so they end up driving more, bringing down plane fares and spiking gas prices.פ
Describe Anchoring + Adjustments (Heuristics)
This iPad should cost $999, but it’s going to be selling it for $499 instead - Initial value anchor and adjusts
- used when making estimations
Problem: initial value are not always relevant, adjustments are not sufficient.
What are three biases in organizations?
Describe overconfidence and the three types.
Unrealistic evaluation of one’s own abilities.
Describe Affect Heuristics
Describe Inattentional Blindness
A. Inability to see things that are just in front of us
B. Problem of attention, not perception
C. Not related to abilities (memory, cognition, expertise)
D. Radiologists only seeing what they are looking for, now what else is in the X-ray.
E. Why can’t we see things? Answer: Expectations, we see what we expect to see, the availability heuristic, cognitive load
Describe some example of Financial Motivation
Money, Status, Promotion
