Economics
Economics:

  • The study of how people seek to satisfy their needs and wants by making choices about how to use scarce resources


Needs vs wants

Needs: things NECESSARY for survival

Wants: things we desire but are NOT ESSENTIAL to survival

Needs vs. Wants


Scarcity
Scarcity

  • Limited quantities of resources to meet unlimited wants


Shortage
Shortage

  • A situation in which a good or service is unavailable temporarily


Factors of production
Factors of Production

  • Land

  • Labor

  • Capital

    • Human

    • Physical

Remember these!

You will hear them a lot this semester!


Land

Natural resources (land, coal, water, forests, etc.)


Labor
Labor

The effort people devote to a task for which they are paid


Capital
Capital

  • Physical: Human made objects used to create other

    goods and services

  • Human: The skills and knowledge gained by a worker through education and experience


Entrepreneurs
Entrepreneurs

  • Ambitious leaders who combine land, labor, and capital to create and market new goods and services.


Factors of Production Model

LAND - cotton

LABOR -seamstress

ENTREPRENEUR –designer, business owner

GOOD – t-shirt

CAPITAL – thread, sewing machine.

Production possibilities curves
Production Possibilities Curves

  • Graphs that show alternative ways to use an economy’s resources

Efficiency
Efficiency

  • Efficiency means using resources in such a way as to maximize the production of goods and services.

  • An economy producing output levels on the production possibilities frontier is operating efficiently.

Efficiency

  • Efficiency also means that in order to produce more of one good you must give up producing some of the other good.

  • This is because the line represents the limits that scarce resources place on our production possibilities.

Underutilization
Underutilization

  • Any point inside the line indicates an underutilization of resources.

  • This economy is not using all of the resources that are available.

  • This economy is not producing all the goods and services it could be producing.

Growth
Growth

  • Growth If more resources become available, or if technology improves, an economy can increase its level of output and grow. When this happens, the entire production possibilities curve “shifts to the right.”

Law of increasing costs
Law of Increasing Costs

  • As we shift resources from making one good to another, the cost of producing the second item increases.

  • In other words, we have to give up more and more of the first item for each additional unit of the second item.

  • This is because some resources are better suited for one purpose over another.
