2. Macroeconomics can best be described as the: A) analysis of how a consumer tries to spend income. B) study of the aggregates of the economy or the economy as a whole.

Why do people trade?1. Assume people didn’t trade. What things would
you have to go without? Everything you don’t produce yourself!
(Clothes, car, cell phone, bananas, heath care, etc)The Point: Everyone specializes in the production of
goods and services and trades it to others 2. What would life be like if cities couldn’t trade
with cities or states couldn’t trade with states?Limiting trade would reduce people’s choices and
make people worse off. The Point: More access to trade means more
choices and a higher standard of living. 8

Per Unit Opportunity Cost Review
Assume it costs you $50 to produce 5 t-shirts. What is your PER UNIT cost for each shirt?
$10 per shirt
Now, take money our of the equation. Instead of producing 5 shirts you could have made 10 hats.
1. What is your PER UNIT OPPORTUNITY COST for each shirt in terms of hats given up?
1 shirt costs 2 hats 2. What is your PER UNIT OPPORTUNITY COST for each hat
in terms of shirts given up? 1 hat costs a half of a shirt 10

Per Unit Opportunity Cost ReviewRonald McDonald can produce 20 pizzas or 200 burgers
Papa John can produce 100 pizzas or 200 burgers1. What is Ronald’s opportunity cost for one pizza in terms
of burgers given up?2. What is Ronald’s opportunity cost for one burger in
terms of pizza given up?3. What is Papa John’s opportunity cost for one pizza in
terms of burgers given up?4. What is Papa John’s opportunity cost for one burger in
terms of pizza given up?

Ronald has a COMPARATIVE ADVANTGE in the production of burgers
Papa John has a COMPARATIVE ADVANTAGE in the production of pizza
1 pizza cost 10 burgers
1 burger costs 1/10 pizza
1 pizza costs 2 burgers
1 burger costs 1/2 pizza
![Page 12: 1. As a consumer, you decide to go to a movie: A)if the marginal cost of the movie exceeds its marginal benefit. B)if the marginal benefit of the movie](https://reader033.vdocuments.mx/reader033/viewer/2022051001/5697bf721a28abf838c7e640/html5/thumbnails/12.jpg)
Absolute and Comparative AdvantageAbsolute Advantage• The producer that can produce the most output OR
requires the least amount of inputs (resources)• Ex: Papa John has an absolute advantage in pizzas
because he can produce 100 and Ronald can only make 20.
Comparative Advantage• The producer with the lowest opportunity cost.• Ex: Ronald has a comparative advantage in burgers
because he has a lowest PER UNIT opportunity cost.
12
Countries should trade if they have a relatively lower opportunity cost.
They should specialize in the good that is “cheaper” for them to produce.

Kenya wants RadiosIf the terms of trade for 1 radio is greater than 3 pineapples then Kenya is worse off and should make radios on their own.India wants PineapplesIf the terms of trade for 1 radio is less than 1 pineapple then India is worse off and should make pineapples on their own.
What terms of trade benefit both countries?

Trading 1 radio for 2 pineapples will benefit bothIf Kenya produces radios by themselves, they give up 3 Pineapples for each radio. If they can trade 2 pineapples for each radio they are better off. If India produces pineapples by themselves, they give up 1 pineapple for one radio. If they can get 2 pineapples for one radio they are better off.The countries trade at a lower opportunity cost than
if they made the products themselves!

Comparative Advantage PracticeCreate a chart for each of the following problems. • First- Identify if it is a output or input question • Second-Identify who has the ABSOLUTE ADVANTAGE• Third-Identify who has a COMPARATIVE ADVANTAGE• Fourth- Identify how they should specialize
1. Sara gives 2 haircuts or 1 perm and hour. Megan gives 3 haircuts or 2 perms per hour.
2. Justin fixes 4 flats or 8 brakes per day. Tim fixes 1 flats or 5 brakes per day.
3. Hannah takes 30 minutes to wash dishes and 1 hour to vacuum the house. Kevin takes 15 minutes to wash dishes and 45 minutes to vacuum.
4. Americans produce 50 computers or 50 TVs per hour. Chinese produce 30 computers or 40 TVs per hour.
