1
Q

A
  • Non-Satiation assumption:
    - Never satisfied with what you have
    - –> Always a good which they prefer over their current one
  • Perfection information
  • Completeness assumption:
    - We are weighing up all the different information, we can rank up the information according to the preferences

A

Irrational assumption or belief that affects the ability to make a decision based on facts and evidence”

Referring to making decisions in a practical and approximate way without having to be exact. This makes it difficult to make rational and instantaneous decisions

Q

What is “availability bias”?

A

Availability bias occurs when people overestimate the likelihood of an event, or the frequency of its occurrence either because something similar occurred recently OR because they are very emotional about a similar event.
EG.
–> Shark attack in Australia
–> 911 Terrorist attack

Q

What is “bounded rationality”?

A

Theory states that rationality is limited (eg. due to time constraint OR asymmetric information).
Furthermore, people do not particularly like choice, especially when there are too many. So, people tend to behave automatically.
