Section 1.2 – Opportunity Cost

MAKING ECONOMIC DECISIONSMAKING ECONOMIC DECISIONS

• The most desirable of the options you pass up is called the Opportunity Cost

• Rank sleep, studying, and playing video games 1st, 2nd, and 3rd on a list for what you value the most


•Every decision we make involves trade-offs – alternatives that we must give up when we make a choice• Example – “I could stay up for 3 hours playing Halo, study, or sleep.”


•1st Place is what you would choose to do

•2nd Place is your opportunity cost (you give it up to do option 1)


• What other option do you have other than using 3 hours for one task?

• You could split your time among multiple activities!

• Thinking at the Margin – decision involving adding one unit and subtracting one unit, rather than all or nothing


OptionsOptions BenefitBenefit Opportunity CostOpportunity Cost

• There is a point at which you are paying the same increase in cost, but seeing lower benefits

• You must make the decision as to whether the cost is worth it

• This same process is used by businesses and consumers to make decisions

GRAPHS….

• WHY do graphs sometimes show information more clearly than text or tables?

Section 1.3 – Production Possibilities Curves

PRODUCTION POSSIBILITIESPRODUCTION POSSIBILITIES

•Production Possibilities Graph – shows alternatives to what an economy can produce•Let’s say we can produce 2 things: Guns and Butter


• Production Possibilities Graph – shows alternatives to what an economy can produce• The outer red line shows the maximum possible output with any given combination

• This is the Production Possibilities Frontier (or Curve)


•To move from one point to another, the economy must make trade-offs


• Any point along the line shows the economy operating at maximum efficiency

• Any point below the line is underutilization – they are not getting all that they could

• Any point above the line is presently impossible, until new resources are available


• Why does the graph curve instead of making a straight line?• Law of Increasing Costs – as production increases for one item, more and more resources are necessary to increase production of the second item! The OPPORTUNITY COST increases…


• Every resource is best suited for certain types of goods• Farmland and cows make butter• Metals and factories make guns and many times you hear about butter vs. guns due to military spending on weaponry using resources …

• To convert butter production to guns, you must sell the cows and build new factories on the land

QUIZ TIME …

• 1. The economic concept of guns or butter means that …• a. a person can spend extra money either on

sports equipment or food.• b. a company must decide whether to

manufacture guns or butter• c. a government must decide whether to

produce more or less military or consumer goods

• d. a government can buy unlimited military and civilian goods if it is rich enough

ANSWER …

• c. a government must decide whether to produce more or less military or consumer goods … trade off …. due to scarcity!

•2. A production possibilities curve shows the relationship between the production of:

• a. farm goods and factory goods• b. two types of farm goods• c. two types of factory goods• d. any two categories of goods

ANSWER

• d. any two categories of goods.

NEXT …

• 3. The line on a production possibilities curve showing the relative amounts of two types of goods produced using all resources is called the• a. production possibilities frontier• b. opportunity cost line• c. utilization of resources• d. maximum possible production line

ANSWER …

• a. production possibilities frontier

QUESTION …

• 4. The law of increasing costs means that as production shifts from one item to another,

• • a. the cost of production gets cheaper and

cheaper.• b. the cost of producing an item stays the same

no matter how many are produced.• c. more and more resources are necessary to

increase production of the second item• d. the land costs of increasing production rise

much more steeply than do the labor costs

ANSWER IS …

• c. more and more resources are necessary to increase production of the second item

AND LAST QUESTION …

• 5. The curve usually seen in a production possibilities frontier can be explained by:• a. growth in the economy• b. underutilization of resources• c. increasing an economy’s efficiency• d. the law of increasing costs

FINAL ANSWER IS …

• d. the law of increasing costs!

AN ECONOMY THAT IS EFFICIENT IS …

Producing the maximum amount of goods and

services .. now that’s efficient!
