Economics
Discipline that studies how efficient decisions are made
Efficient Decisions
Choosing the most valuable alternative
Theory of Revealed Preference
Our choices reveal our values
3 Characteristics of Value
- Value depends on the situation
- Value is different for different people
- Subsequent units of some good have lesser value
Optimal Arrangement Principle
The most valued good is always our first choice, the next most valued is our second, and so on.
Value of something to an individual
What one is willing to sacrifice or exchange in order to acquire something else
Why do we value money?
We value money for what we can get in exchange with it.
Cost
Value of the best alternative that we sacrifice when an economic choices made
No Free Lunch
Decisions have at least two alternatives and one must be chosen and one must be sacrificed. The alternative that we sacrifice involves cost due to us sacrificing it.

Scarcity
When there is more wants than resources to satisfy those wants
Goods

Marginal Value
Value of an individual unit
Marginal Analysis
Relationship between economic variables (cost & value).
Marginal value is at least as great as marginal cost.
Law of Diminishing Returns
Adding more individuals to a work area decreases productivity due to the excess of people in the small work area.
Demand

Supply
Relationship between possible prices and quantities people are willing to sell
Equilibrium Price
When supply and demand is intersects (is equal). Consumers can buy all they want and producers can sell all they want.

Social Gain= Marginal Value-Marginal Cost
Consumer’s Gain
Total Value-Total Amount Paid
Producer’s Gain
Total Amount Paid-Total Cost
