WHAT ARE THE THINGS YOU LEARNED ABOUT ECONOMICS.

ECONOMICS AS A SOCIAL SCIENCE

CONCERNED WITH THE STUDY OF HUMAN BEHAVIOR AND PRACTICES TO EFFECIENTLY USE THE SCARCE RESOURCES TO ACHIEVE MAN’S SATISFACTION.

DEAL HOW PEOPLE MAKE A LIVING AND HOW SOCIETY PROVIDES ALL THE NEEDS OF MAN.

MICROECONOMICS

CENTERED IN DISCUSSING THE SMALL UNIT OF THE ECONOMY.

TACKLED THE BEHAVIOR OF THE CONSUMERS,PRODUCERS AND THE MARKET..

HOW DO INDIVIDULA MAKE ECONOMIC DECISIONS?

MACROECONOMICS

STUDY THE BEHAVIOR OF THE ENTIRE ECONOMY.

FOCUSES ON THE AGGREGATE ACTIVITIES OF THE GOVERNMENT, INDUSTRY AND HOUSEHOLD.

BIG PICTURE:GROWTH, EMPLOYMENT.CHOICES MADE BY LARGE GROUP.

FIVE ECONOMIC QUESTIONS

Society (we) must figure out

• WHAT to produce (make)• HOW MUCH to produce

(quantity)• HOW to Produce it

(manufacture)• FOR WHOM to Produce

(who gets what)• WHO gets to make these

decisions?

STUDIES THE CHOICES AND DECISION OF PEOPLE AND SOCEITY.

ECONOMISTS

SCARCITY: unlimited wants and needs but limited resources

BUT, there’s a Fundamental Problem:

THE RESOURCES ARE LIMITED

TO SATISFY THE UNLIMITED WANTS AND NEEDS OF PEOPLE.

• Because ALL resources, goods, and services are limited – WE MUST MAKE CHOICES!!!!

CHOICE..CHOICE..CHOICE….

Why Choices?

We make choices about how we spend our money, time, and energy so we can fulfill our NEEDS and WANTS.

What are NEEDS and WANTS?

VS.

• NEEDS – “stuff” we must have to survive, generally: food, shelter, clothing

• WANTS – “stuff” we would really like to have (Fancy food, shelter, clothing, big screen TVs, jewelry, conveniences . . . Also known as LUXURIES

Wants and Needs, Needs and Wants

TRADE-OFFSWHEN YOU GIVE UP OR SACRIFICE ONE PRODUCT OR ANOTHER.

You can’t have it all (SCARCITY – remember?) so

you have to choose how to spend your money, time, and

energy. These decisions involve picking one thing

over all the other possibilities – a TRADE-OFF!

• What COULD you have done instead of coming to school today?

• These are all Trade-Offs!

THE COST OF TRADE OFF IS

OPPORTUNITY COST.

OPPORTUNITY COST =

The Value of the Next Best ChoiceEx: Sleeping is the opportunity cost of studying for a test)

THE VALUE OF ALTERNATIVE GIVEN UP TO OBTAIN ANOTHER ITEM.

• This is really IMPORTANT – when you choose to do ONE thing, its value (how much it is worth) is measured by the value of the NEXT BEST CHOICE.– This can be in time, energy, or even

MONEYIf I buy a pizza…

Then I can’t afford the movies…

Q: What is the opportunity cost of buying pizza?

PEOPLE NEED TO MAKE ANINTELLIGENT DECISION BY EXAMINING THE AVAILABLE ALTERNATIVES TO SATISFY THE UNLIMITED NEEDS AND WANTS.

AS A STUDENT HAS P60.00 ALLOWANCE.HE WILL SPEND THE MONEY FOR HIS SNACK AND PLAYING COMPUTER GAMES. ASSUMING THE BISCUITS FOR SNACK COST P5.00 WHILE PLAYING COMPUTER GAMES IS P15.00 PER HOUR.

ANALYSIS

COMBINATION A3 BISCUITS X P5.00 = P15.003 COMPUTER GAMES X P15.00 = P45.00

= P60.00COMBINATION B6 BISCUITS X P5.00 = P30.002 COMPUTER GAMES X P15.00 = P30.00

= P60.00

CHOOSE THE BEST COMBINATION

1. EXPLAIN THE BEST ALTERNATIVE.2. WHAT WILL BE THE OPPORTUNITY COST AND

OPPORTUNITY BENEFIT OF THE BEST ALTERNATIVE?

1.COMB. A- because you were able to have 3 biscuits and 3 computer games.

2. My opportunity cost is 3 biscuits, the benefit is you can play computer games which you enjoy playing.
