scarcity
we have unlimited wants but limited resources
choices
economics is the study of choices
economics
study of how individuals and societies deal with scarcity
trade-offs
alternatives that we give up whenever we choose one course of action over others
opportunity cost
the most desirable alternative given up as a result of a decision
microeconomics
study of small economic units such as individuals, firms, and industries
macroeconomics
study of the large economy as a whole or economic aggregates
theoretical economics
the use of the scientific method to make generalizations and abstractions to develop theories
policy economics
theories that are applied to fix problems or meet economic goals
positive statements
based on facts. Avoids value judgements (what is)
normative statements
includes value judgements (what ought to be)
utility
satisfaction
marginal
additional
allocate
distribute
shortages
occur when producers will not or cannot offer goods or services at current prices. Shortages are temporary
price
amount buyer (or consumer pays)
cost
amount seller pays to produce a good
investment
the money spent by BUSINESSES to improve their production
goods
physical objects that satisfy needs and wants
consumer goods
created for direct consumption (ex: pizza)
capital goods
created for indirect consumption (ex: over, blenders, knives) - Goods used to make consumer goods
services
actions or activities that one person performs for another (teaching, cleaning, cooking)
accountants
look at only explicit costs
economists
look at explicit and implicit costs
explicit costs
the traditional "out-of pocket costs" of decision making
implicit costs
the opportunity costs such as forgone time and forgone income
Three economic questions
What goods and services should be produced?
How should these goods and services by produced?
Who consumes these goods and services?
economic system
the method used by a society to produce and distribute goods and services
4 factors of production
Land
Labor
Capital
Entrepreneurship
Land
all natural resources that are used to produce goods and services. Anything that comes from "mother nature" (Water, sun, oil)
Labor
any effort a person devotes to a task for which that person is paid (lawyers, doctors, teachers)
Two types of capitals
Physical: any human-made resource that is used to create other goods and services (tools, tractors)
Human capital: any skills or knowledge gained by a worker through education and experience (college, degrees, vocational training
entrepreneurship
ambitious leaders that combine the other factors of production to create goods and services (bill gates, henry ford)
Entrepreneurs
Take the initiative
Innovate
Act as the Risk brearers So they can obtain PROFIT
profit
revenue - costs
you will continue to consume until
Marginal Benefit = Marginal Cost
Utility maximizing rule
the consumer's money should be spent so that the marginal utility per dollar of each good equals each other. it always assumes that you always consume where MU/ for each product is equal
the product market
the "place" where goods and services produced by businesses are sold to households
the resource (factor) markey
the "place" where resources (land, labor, capital, and ent.) are sold to businesses
circular flow model
see image
scarcity means there is not enough for everyone
government must step in to help allocate resources
economic systems
Centrally-Planned (Command) Economy
Free Market Economy
Mixed Economy
Centrally-Planned of Command Economies (aka communism)
owns all the resources
answers the three economic questions NO PROFIT MEANS NO INCENTIVE TO WORK HARDER
Free Market System (aka Capitalism)
Little government involvement in the economy
Individuals OWN resources and answer the three economic questions
The opportunity to make PROFIT gives people INCENTIVE to produce quality items efficiently
Wide variety of goods available to consumers
Competition and Self-Interest work together to regulate the economy (keep prices down and quality up)
The invisible hand (adam smith)
the concept that society's goals will be met as individuals seek their own self-interest. competition and self-interest act as an INVISIBLE HAND that regulars the free market

the production possibilities curve (PPC)
a model that shows alternative ways that an economy can use its scarce resources. it graphically demonstrates scarcity, trade-offs, opportunity costs, and efficiency
4 key assumptions
Only two goods can be produced Full employment of resources Fixed Resources Fixed Technology
constant opportunity cost
resources are easily adaptable for producing either good. result is a straight line PPC (not common)
law of increasing opportunity cost
as you produce more of any good, the opportunity cost (forgone production of another good) will increase. Why? resources are NOT easily adaptable to producing both goods
how much each marginal unit costs
opportunity cost/units gained
productive efficiency
Products are being produced in the least costly way
There is any point ON the PPC
allocative efficiency
The products being produced are the ones most desired by society
This optimal point on the PPC depends on the desires of society
3 shifters of the PPC
Change in resource quantity or quality
Change in Technology
Change in Trade
capital goods and future growth
Countries that produce more capital goods will have more growth in the future.
per unit opportunity cost review
opportunity cost / units gained
absolute advantage
the producer that can produce the most output OR requires the least amount of inputs (resources)
comparative advantage
the producer with the lowest opportunity cost
output questions
other goes over
input questions
other goes under
