1
New cards

economics

how an individual in society experiences limitless wants, and chooses to allocate its limited resources to satisfy wants

2
New cards

microeconomics

study of individual decisions and markets

3
New cards

macroeconomics

study of national and global economies

4
New cards

economic resources

- means of producing goods and services
- all natural, human, and manufactured resources that go into the production of goods and services

5
New cards

utility

any good or service that gives pleasure/satisfaction/usefulness

6
New cards

fundamental economic questions

- FOR WHOM will it be produced?
- WHAT will be produced?
- HOW will it be produced?

7
New cards

market economies/capitalism

- no government regulation
- decisions of individual producers and consumers largely determine what, how, and for for whom to produce
- problem: unequal distribution of power and wealth

8
New cards

command economies/communism

- total government regulation
- industry is publicly owned and a central authority makes production and consumption decisions

9
New cards

mix economies/free enterprise

government regulation and private business control the factors of production

10
New cards

karl marx

favored government control (command economy//communism)

11
New cards

john maynard keynes

favored a mixed economy

12
New cards

adam smith

favored a market economy (lassiez-faire)

13
New cards

positive statements

- objective (non-opinionated) statements that can be tested even if not true
- economists use this

14
New cards

normative statements

subjective (opinions) statements that can't be tested

15
New cards

ceteris paribus

all things stay constant

16
New cards

factors of production

- capital: capital goods and human capital
- entrepreneurial ability: decision maker
- land: natural resources
- labor: physical and mental talents

17
New cards

circular flow diagram

- product market: firms sell, households buy
- factor/resource/labor market: firms buy, households sell

<p>- product market: firms sell, households buy<br>- factor/resource/labor market: firms buy, households sell</p>
18
New cards

households

consumers

19
New cards

firms

businesses/producers

20
New cards

powers of economic thinking

- decisions/resources cost more than you think
- all decisions are made at the margin (MC=MB)
- all decisions are rational
- the answer to most economic questions is "it depends"
- all people/businesses are maximizers

21
New cards

opportunity cost

- the second best option
- what one sacrifices in order to obtain what one wants

22
New cards

production possibility curve

- illustrates the tradeoffs facing an economy that produces only two goods
- recessions and depressions does not affect curve

<p>- illustrates the tradeoffs facing an economy that produces only two goods<br>- recessions and depressions does not affect curve</p>
23
New cards

productive efficiency

- producing goods and services for the lowest cost
- no resources unused
- on the curve

24
New cards

allocative efficiency

- more concerned with the distribution and allocation of resources among society's wants/needs
- below curve

25
New cards

shifters of the PPC

- resources (more=outward)
- technology
- change in trade
- investments

26
New cards

increasing opportunity cost

- resources are not balanced between two goods
- producing more of one good requires giving up an increasing amount of production of the other good

<p>- resources are not balanced between two goods<br>- producing more of one good requires giving up an increasing amount of production of the other good</p>
27
New cards

constant opportunity cost

- resources are balanced between two goods
- resources are easily adaptable for producing either good

<p>- resources are balanced between two goods<br>- resources are easily adaptable for producing either good</p>
28
New cards

absolute advantage

- ability to producing a good with fewer resources than another producer
- input/labor/factor market: smallest #
- output/goods/product market: largest #

29
New cards

comparative advantage

- ability to produce a good with the lowest opportunity cost
- input/labor/factor market: cross-add/smallest #
- output/goods/product market: cross-add/largest #

30
New cards

output opportunity cost

Other goes Over (OOO)

31
New cards

input opportunity cost

Other goes Under (IOU)

32
New cards

theory of consumer choice

- consumer is rational
- consumer is affected by diminishing marginal utility
- consumer faces constraints of income

33
New cards

utility maximizing rule

- should be equal to obtain greatest utility/happiness
- inequality: buy less of product with lower MUx/Px and more of product with higher MUx/Px

<p>- should be equal to obtain greatest utility/happiness<br>- inequality: buy less of product with lower MUx/Px and more of product with higher MUx/Px</p>
34
New cards

total utility

total amount of satisfaction obtained from consumption of a good or service

35
New cards

marginal utility

satisfaction or usefulness obtained from acquiring one more unit of a product

36
New cards

factor/resource market

where resources (capital and labor) are bought and sold

37
New cards

product market

goods and services are bought or sold

38
New cards

capital goods

goods that produce other goods for future use

39
New cards

consumer goods

products and services that satisfy human wants directly

40
New cards

marginal analysis

involves comparing marginal benefits and marginal costs
