What Does Economics Study?

3 Key Economic Assumptions
1. Society’s wants are unlimited, but ALL resources are limited (scarcity).
2. Due to scarcity, choices must be made. Every choice has a cost (a trade-off).
3. Everyone’s goal is to make choices that maximize their satisfaction. Everyone acts in their own “self- interest.”
TASK 2 : Think of a particular example/situation to illustrate the assumptions.
TASK: Given the following assumptions, make a rational choice in your own self-interest

1. You have a friend abroad and want to visit him for the weekend
2. You work every weekday earning 100LT per day
3. You have three flights to choose from:
• Thursday Night Flight = 300LT
• Friday Early Morning Flight = 345LT
• Friday Night Flight = 380LT
Which flight should you choose? Why?
