WHY ARE SCARCITY/CHOICE BASIS OF ECONOMICS? How does Scarcity force people to make

economic choices? Makes everyone make choices by making us

decide which options are most important to us Scarcity states there are limited goods/services

for unlimited wants. People need to make choices in order to satisfy m/i

wants People satisfy their needs/wants w/

goods/services People’s needs/wants are unlimited, goods/services are

not

WHY ARE SCARCITY/CHOICE BASIS OF ECONOMICS? Economics begins w/idea that people cannot

have everything they want/need The fact that limited amounts of goods and

services are available to meet unlimited wants is called scarcity. Scarcity forces people to make choices but it is

not the same as a shortage. Shortages are temporary while scarcity always

exists.

WHAT DO ENTREPRENEURS DO? Entrepreneurs play a key role in turning

scarce resources into goods/services Willing to take risks in order to make a profit They:….

Develop original ideas Start businesses Create new industries Fuel economic growth

1st Task is to assemble factors of production Land Labor Capital

FACTORS OF PRODUCTION: LAND Refers to all natural resources used to

produce goods/services Resources include:

Fertile land for farming Oil Coal Iron Water Forests

FACTORS OF PRODUCTION: LABOR Labor is the effort people devote to tasks for

$$ Labor includes:

Medical care provided by a doctor Instruction provided by a teacher Tightening of a bolt by an assembly-line worker Creation of painting by an artist Repair of television by technician

FACTORS OF PRODUCTION: CAPITAL Refers to any human-made resource that is

used to produce other goods/services Economy requires both human/physical

capital Physical

Buildings Equipment Tools

Human College education Training Job experience

BENEFITS OF CAPITAL Key factor for production b/c people and

companies can use it to save time/money Benefits of capital

Increased efficiency Increased knowledge Better time-management Increased productivity

SCARCE RESOURCESCheckpoint: Why are

goods/services scarce? Goods/services are scarce b/c the resources used

to produce them are scarce Only so many natural resources available to

produce goods Labor for production can be limited Physical capital can be limited for many

industries Each resource may have alternative uses

People, businesses, govt.s must choose which alternative they want most

S.2: OPPORTUNITY COST Guiding Question

How does opportunity cost affect decision making? Write at top of S.2 Notes

Objectives to learn Why every decision involves trade-offs The concept of opportunity cost How people make decisions by thinking @ the

margin Key Terms

HOW DOES OPPORTUNITY COST AFFECT DECISION MAKING? Every time we choose to do one thing, we are

giving up the opportunity to do another When we make decisions about how to spend

our scarce resources, like money/time, we give up our chance on something else

All indiv’s, businesses, and large groups make decisions that involve trade-offs

Trade-offs involve things easily/not easily measured Money, property, time, and things not easily

(enjoyment or job satisfaction)

HOW DOES OPPORTUNITY COST AFFECT DECISION MAKING? Businesses and Govt. trade-offs

Businesses make trade-offs when they decide how to use their factors of production Famer uses land to plant corn, cannot use same land

to plant soybeans Govt’s make trade-offs when they decide to

spend money on military needs instead of domestic, or vice-versa

Checkpoint: What are trade-offs? Answer economics and you from BW

WHAT IS OPPORTUNITY COST? Most trade-offs have

one of the “rejected” alternatives being more “desirable” than rest

That most desirable alternative given up by the decision is the opportunity cost

HOW DO PEOPLE MAKE DECISIONS Decision making grid

Can help you decide if you are willing to accept the opportunity cost of a choice

Read thru pg. 10 Answer 2 ?s

Thinking @ the Margin When you decide how

much/less to do you are thinking on the margin

Involves comparing opportunity costs/benefits Called cost/benefit

analysis

THINKING AT THE MARGIN Marginal Costs and Benefits

To make good decisions you must weigh the marginal costs against marginal benefits M.Cost = extra cost of adding one unit such as sleeping

or getting one more cookie M. Benefit = extra benefit from adding one unit such as

sleeping or getting one more cookie Once the marginal costs outweigh the marginal

benefit, no more units can (or will) be added Example: 1 more cookie is o.k. b/c it is only 35 more

calories but once the unit cost (calories) exceeds what the benefit (satisfaction) is you will not add anymore.

Best example is how often you tell yourself you can “sleep just ____ much longer” before there is a cost you aren’t willing to put up with

COST/BENEFIT ANALYSIS Read and answer figure 1.1 on making

decisions at the margin Answer the 2 ?s

Decision making at the margin Like opportunity cost, thinking at the margin

applies to businesses/governments as well Employers think @ margin when they decide how

many workers to hire Legislators think @ margin when they decide how

much to increase govt. spending on a project

S3: PRODUCTION POSSIBILITIES CURVES Guiding Question

“How does a nation decide what/how much to produce?” Write at top of S3 notes

Learning Objectives Interpret a PPC Explain how PPC’s show efficiency, growth, and

cost Why a country’s production possibilities depend

on its resources and technology Key Terms

http://www.pearsonsuccessnet.com/snpapp/iText/products/0-13-369833-5/Flash/Ch01/Econ_OnlineLectureNotes_ch1_s3.swf

HOW DOES A NATION DECIDE WHAT/HOW MUCH TO PRODUCE? PPC CURVES!! To help decisions, economists use PPCs as a tool

Curve helps nation’s economists determine alternative ways of using a nation’s resources

Production Possibilities Economists use graphs to analyze choices/trade-offs that

people make To draw PPC, begin by deciding which goods/services to

examine. Refer to graph, pg. 14

Production Possibilities Frontier Line that shows the maximum possible output an

economy can produce Each point reflects a trade-off

Happens b/c factors of production are scarce L, L, and C to make one product means fewer of those to make

the other

WHAT DO PPCS SHOW? Efficiency

PPF represents an economy working at its most efficient level

Economies can work inefficiently, using fewer resources than capable. Underutilization

Growth When an economy grows the curve shifts to right

Production capacity can also decrease, leading to shift left Cost: Can help show the opportunity costs of

Decisions Cost increases as production shifts from making one item to

another Law of Increasing Costs: Refer to Chart pg. 17

Explains as we move along the curve, we trade off more & more for less & less output

TECHNOLOGY AND EDUCATION Technology can increase a nation’s efficiency Govt.’s spend $$ investing in new tech.,

education and training for workforce
