• Why?– Because our needs
and wants are insatiable and our resources are finite

Human BehaviourHuman Behaviour
• Rational and social beings therefore we are able to predict the groups behaviour but not always the individuals that make up the group.
• Knowledge of the group behaviour can be useful for decision makers.

Economic decisions need to be both effective and efficient
Efficiency means we have to realise we give up
something else to achieve our goals

TOP 10 REASONS TO STUDY ECONOMICS
1. Economists are armed and dangerous: "Watch out for our invisible hands.”
2. When you call 1-900-LUV-ECON and get Kandi Keynes, you will
have something to talk about. 3. You can talk about money without every having to make any.
