Q

DIVISIONS OF ECONOMICS

A

“Every individual endeavors to employ his capital so that its produce may be of greatest value. He generally neither intends to promote the public interest, nor knows how much he is promoting it. He intends only his own security, only his own gain. And he is in this led by the invisible hand to promote an end which was no part of his intention. By pursuing his own interest, he frequently promotes that of society more effectually than when he really intends to prove it”

33
Q

who created the 10 principles of economics?

A

Nicholas Gregory Mankiw

34
Q
  • The value of the good or service foregone.
  • The value of the next best choice that you give up when you make an economic/rational decision.
A

under principle 2:

OPPORTUNITY COST

35
Q
  • Costs that we make in the past that we cannot recover.
A

under principle 2:

SUNK COST

36
Q

who systematically and purposefully do the best they can to achieve their objectives given the available opportunities.

A

under principle 3:

RATIONAL PEOPLE

37
Q

small incremental adjustments to a plan of
action.

A

under principle 3:

MARGINAL CHANGES

38
Q

something that induces a person to
act, i.e. the prospect of a reward or punishment.

A

under principle 4:

INCENTIVE

39
Q

a group of buyers and sellers (need not be in a single location)

A

under principle 6:

MARKET

40
Q

allocates resources through the decentralized decisions of many households and firms as they interact in markets.

A

under principle 6:

MARKET ECONOMY

41
Q
  • This means that we all have the freedom to buy the properties that we want, products/services that we need, and firms has right to produce, etc.
  • People have met their basic survival need and have enough/sufficient income to prosper
A

economic well-being

42
Q
  • llustrates the hidden economic factors that affect/guide the buying behavior of the
    consumers(households) and the activities of sellers/firms/etc.
  • eg. price, quality, credibility, quantity, self-interest(base on the benefits that they will get in the product),
A

under principle 6:

THE INVISIBLE HAND

43
Q
  • the amount of goods and services produced per unit of labor.
  • depends on the equipment, skills, and technology available to workers.
A

under principle 8:

PRODUCTIVITY

44
Q

increases in the general level of prices.

A

under principle 9:

INFLATION

45
Q

Examples:

Going to a party the night before your midterm
leaves less time for studying.

Having more money to buy stuff requires
working longer hours, which leaves less time
for leisure.

Protecting the environment requires resources
that could otherwise

A

PRINCIPLE 1: People Face Tradeoffs.

46
Q

Making decisions requires comparing the costs
and benefits of alternative choices.

The opportunity cost of any item is
whatever must be given up to obtain it.

It is the relevant cost for decision making.

A

PRINCIPLE 2: The Cost of Something Is What You Give Up to Get It.

47
Q

Examples:
The opportunity cost of…

…going to college for a year is not just the tuition,
books, and fees, but also the foregone wages.

…seeing a movie is not just the price of the ticket,
but the value of the time you spend in the theater.

A

PRINCIPLE 2: The Cost of Something Is What You Give Up to Get It.

48
Q

systematically and purposefully do the best they
can to achieve their objectives.

make decisions by evaluating costs and benefits
of marginal changes, incremental adjustments
to an existing plan.

A

PRINCIPLE 3: Rational People Think at the Margin

49
Q

Examples:

When a student considers whether to go to
college for an additional year, he compares the
fees & foregone wages to the extra income
he could earn with the extra year of education.

When a manager considers whether to increase
output, she compares the cost of the needed
labor and materials to the extra revenue.

A

PRINCIPLE 3: Rational People Think at the Margin

50
Q

Examples:

When gas prices rise, consumers buy more
hybrid cars and fewer gas guzzling SUVs.

When cigarette taxes increase,
teen smoking falls.

A

PRINCIPLE 4: People Respond to Incentives

51
Q

Rather than being self-sufficient,
people can specialize in producing one good or
service and exchange it for other goods.

Countries also benefit from trade and
specialization:
- Get a better price abroad for goods they produce
- Buy other goods more cheaply from abroad than
could be produced at home

A

PRINCIPLE 5
Trade Can Make Everyone Better Off

52
Q

“Organize economic activity” means determining what goods to produce, how to produce them, how much of each to produce, who gets them

A

PRINCIPLE 6: Markets Are Usually A Good Way to Organize Economic Activity

53
Q

Famous insight by Adam Smith in
The Wealth of Nations (1776):

Each of these households and firms
acts as if “led by an invisible hand”
to promote general economic well-being.

A

PRINCIPLE 6: Markets Are Usually A Good Way to Organize Economic Activity

54
Q

The invisible hand works through the price
system:

The interaction of buyers and sellers
determines prices.

Each price reflects the good’s value to buyers
and the cost of producing the good.

Prices guide self-interested households and
firms to make decisions that, in many cases,
maximize society’s economic well-being.

A

PRINCIPLE 6: Markets Are Usually A Good Way to Organize Economic Activity

55
Q

“There ain’t no such thing as a free lunch.”

To get one thing that we like, we usually have to give
up another thing that we like. Making decisions
requires trading off one goal against another.

A

PRINCIPLE 1: People Face Tradeoffs.

56
Q

Important role for govt: enforce property rights
(with police, courts)

People are less inclined to work, produce, invest,
or purchase if large risk of their property being
stolen.

A

PRINCIPLE 7: Governments Can Sometimes
Improve Market Outcomes

57
Q

Govt may alter market outcome to
promote equity.

If the market’s distribution of economic well-being
is not desirable, tax or welfare policies can
change how the economic “pie” is divided.

A

PRINCIPLE 7: Governments Can Sometimes
Improve Market Outcomes

58
Q

Huge variation in living standards across
countries and over time:

Average income in rich countries is more than
ten times average income in poor countries.

The U.S. standard of living today is about
eight times larger than 100 years ago.

A

PRINCIPLE 8: A Country’s Standard of Living Depends on Its Ability to Produce Goods & Services

59
Q

The most important determinant of living
standards: productivity, the amount of goods
and services produced per unit of labor.

Productivity depends on the equipment, skills,
and technology available to workers.

Other factors (e.g., labor unions, competition from
abroad) have far less impact on living standards.

A

PRINCIPLE 8: A Country’s Standard of Living Depends on Its Ability to Produce Goods & Services

60
Q

Inflation: increases in the general level of prices.

In the long run, inflation is almost always caused
by excessive growth in the quantity of money,
which causes the value of money to fall.

The faster the govt creates money,
the greater the inflation rate.

A

PRINCIPLE 9: Prices Rise When the Government Prints
Too Much Money

61
Q

In the short-run (1–2 years),
many economic policies push inflation and
unemployment in opposite directions.

Other factors can make this tradeoff more or less
favorable, but the tradeoff is always present.

A

PRINCIPLE 10: Society Faces a Short-run Tradeoff Between Inflation and Unemployment

62
Q

the cost of any action is measured in terms of?

A

foregone opportunities

63
Q

rational people make decisions by?

A

comparing marginal costs and marginal benefit

64
Q

it is is the ultimate source of living
standards?

A

productivity

65
Q

it is the ultimate source of inflation?

A

money growth

66
Q

what are the two roles of the government?

A
  1. alter market outcome to promote equity
  2. can change how the economic “pie” is divided.
