Graphs:
- Straight-line:
- Horizontal Axis:
- Vertical Axis:
- Zero slope:
SL- linear line.
HA- Independent variable.
VS- Dependent variable.
ZS- variables that unrelated to each other.
Independent variable-
the source that causes problems. Things we control and manipulate to see changes in DV.
Dependent variable-
The outcome. Changes caused by IV.
Direct relationship-
Both axes increase in the same direction.
Inverse relationship-
2 axis change in opposite direction.
Slope of a straight line-
vertical/horizontal change.
Linear equation-
y=a+bx
What is a utility?
Pleasure, happiness from consuming a good.
Marginal analysis?
“Change” To have marginal benefit, we have to give up marginal cost.
Scarcity-
limited resources with unlimited want.
Opportunity cost-
To obtain more thing, we give up something else.

- Capital- fund, money, investment.
- Entrepreneurial ability- combines land, labor, and capital. Putting together to produce good and services.
Production possibility model-
Looking at possible output we have based on what we used.
Marginal Benefit-
what people are willing to give up to obtain more goods.
Marginal cost-
The value of what is given up to produce additional unit. MB=MC
Economics-
The study of how we make decisions upon scarcity.
Adam Smith’s Division of Labor-
People earn money by specialized in something.
Specialization-
Allows workers to work to their advantage. Produce more rapidly and higher quality.
Specialization allows:
Economic of scale-
Core competency-
Focus on advantages.
Economic of scale- more production= cost drops.
Core competency- business focus on fewer products is more successful.
Encourage workers to invent and learn.
Microeconomics-
Focus on individual, firms, industries w/i the economy.
Macroeconomics-
Focus on whole economy: growth of production, standard of living, unemployment…
Micro-
Make decision based on macro economy (economy is growing out or not).
Macro-
Make decision based on micro economy (individual).
Fiscal policy-
Gov’t spending and taxes.
Monetary policy-
Level of interest rates, borrowing.
Circular flow diagram
shows how the economy flows by 2 groups: household and firms.
Goods and services-
Where firms sell.
Labor market-
where households sell.
Traditional economy-
Oldest one around. Occupation stay in the family. Most people turned farmers. Little economic development.

Market economy-
Based on private enterprise. Business supply goods and services based on demand. Income based on labor.

Capital goods-
Factor of Production created by people.
Saving-
someone consumes LESS than their income.
Investment-
