-GDP
-CPI
-Inflation and Deflation
-Total employment and unemployment

Gross Domestic Product (GDP) - ANSWER-total output of all goods and services produced within
the boundaries of a country (tangible(food, clothing, cars) and intangible goods (haircuts, house
cleaning, doctor's visits))

Consumer Price Index (CPI) - ANSWER-The average level of prices of all consumer goods and
services

Economics - ANSWER-the study of how scarce resources are allocated among their competing uses
-it's about limited resources and unlimited wants

Factors of production (resources) - ANSWER-land, labor, capital, entrepreneurship (LLEC)

Land - ANSWER--encompasses the land that production takes place and all natural resources:
water, sheep, cows, metal, timber, minerals
-Renewable and non-renewable resources

Labor - ANSWER--the physical and mental abilities of workers
-Quantity and quality (human capital)
-Fixed wages

Capital - ANSWER--goods produced in the economy that are used to produce other goods and
services
-Machines, tools, structures (buildings, factories)

Entrepreneurs - ANSWER--An individual who organizes resources for production, might introduce
new products or techniques.
-Returns vary: reaps the rewards (profits) or bears the consequences (losses)
-Hallmark of the entrepreneur is innovation and risk taking.

Supply and Demand - ANSWER--determines how we use resources
-this also determines the market value

,Adam Smith - ANSWER--The Father of Modern Economics
-The Wealth of Nations in 1776
-Invisible hand: Households and firms interacting in markets guided by process and self-interest,
Leads to the most efficient outcomes
-Wrote about producers benefitting through specilozation in trade and Absolute advantage

Efficiency - ANSWER-getting the most that we can out of our scarce resources (maximum output)

Equity - ANSWER--distributing output in a fair manner
-Examples: progressive income tax system (equity, trying to distribute money more fairly),
unemployment benefits

opportunity cost - ANSWER--Whatever must be given to obtain some item
-Cost of the alternative
-Coming to college after high school
-Opportunity cost college: full-time current wages
-Opportunity cost work: education, higher future wages
-Could be constant resulting in a straight line PPF, or increasing resulting in a concave PPF
-The opportunity cost of a good increases as more of the good is produced.
-Why? Resources are not equally efficient in the production of both goods.
-Some resources are better suited to one task than another. The first resources to "switch" are the
one best suited to switching.

Production Possibility Frontier (PPF) - ANSWER-A graph that shows the combinations of output that
the economy can possibly produce given the available factors of production and the available
production technology

PPF Graphs - ANSWER-The company can produce any combination on or inside the line
Points outside are NOT feasible given the economy's resources
The slope measures the oppurtunity cost
Points on (rather than in) the PPF represent efficeint levels of production, once we have reached the
efficiency point in the possibilities frontier, this shows a trade off; the only way to produce more of
one good is to produce less of others

Efficient production - ANSWER-Production is said to be efficient when a country achieves maximum
output from its resources. Producing less than maximum output occurs when resources are left idle
or used ineffectively. Any points below the PPF are inefficient Only points on the PPF signify efficient
production. Thus the PPF consists of all combinations of output that are both feasible and produced
efficiently.
