ECON midterm review: chapter 1
After graduating from high school, Ron Willis plans to go to college. The college tuition is $15,000 a year. But, instead of going to college, Ron could take a full-time job paying $20,000. If Ron decides to go to college, what is his opportunity cost for attending for one year? $5,000 $15,000 $20,000 $35,000
$35,000
Lady Gaga tickets are $60 but, you're willing to pay a maximum of $100 to see her. You got a free Ed Sheeran ticket and you're; considering seeing him on the same night. What is the OC of seeing Ed Sherran?
$40
Shift or pivot in the PPC is due to changes in
- resource quantity - resource productivity - technology improvements
Shift or pivot in budget line
Income changes Prices change Afford more/less
Oppurtunity cost
What is given up when making one choice instead of another "there is no free lunch"
The Budget line / curve
traces combinations of (two) goods that can be bought using one's entire income or budget
PPC (Production Possibilities Curve)
traces combinations of (two) goods that can be produced using one's production resources - how we represent scarcity principle for producers
Comparative advantage (2 person economy)
the ability to produce a good at a lower opportunity cost than another producer
Absolute advantage (2 person economy)
the ability to produce more of a good using the same or fewer inputs than another producer
We represent the scarcity principle for consumers is
the budget line
Molly decides to spend three hours working overtime rather than watching video with her friends. She earns $8 an hour. Her opportunity cost of working overtime is: A) the enjoyment she would have received had she watched the video. B) the $24 she earns working. C) the $24 minus the enjoyment she would have received from watching the video. D) nothing, since she would have received less than $24 of enjoyment from the video.
the enjoyment she would have received had she watched the video.
Why is the shape of a two person PPC concave?
the fact that the economy moves towards producing more of just one good, it has to give up an increasing amount of the other good
Lady Gaga tickets are $60 but, you're willing to pay a maximum of $100 to see her. An Ed Sheeran ticket is $10 and you're considering seeing him on the same night. What is the OC of seeing Ed Sherran?
40 + 10 = $50 (NB of lady gaga and OC of Ed Sheeran)

Scarcity Principle for Consumers
Because of limited incomes or budgets, in order to consume more of something, we must give up the consumption of something else
Scarcity Principle for Producers
Because of limited resources (time, manpower, machinery), in order to produce more of something, we must give up the production of something else
Suppose you have a budget of $200 which you can spend on either Washington apples ($1 a unit) or Honeycrisp apples ($2 a unit). If your budget doubles to $400, the price of Washingtons stays the same, while the price Honeycrisps also double, then your budget line _____________. A) Shifts in a parallel manner up / outward / to the right B) Shifts in a parallel manner down / inward / to the left C) Pivots outward D) Stays the same
C
Are the goods that businesses offer for "free" to consumers also free to society? A) Yes, because the individual consumer does not have to pay for them. B) Yes, because the marginal benefit is greater than the marginal cost. C) No, because scarce resources were used to produce the free goods. D) No, because society does not assign a value to free goods.
C) No, because scarce resources were used to produce the free goods.
Assume that a consumer purchases two products and the consumer's money income increases. All other things equal, the most likely effect is: A) an outward shift in the production possibilities curve because the consumer can now satisfy more wants. B) an inward shift in the budget line because the consumer can now purchase less of both products. C) an outward shift in the budget line because the consumer can now purchase more of both products.

Shape of two person PPC
In a two or many person economy, the PPC is bowed out or concave due to the principle of increasing OC
Why does the budget line have a downward sloping shape?
Represents the fact that to consume more of one good, we must give up another (due to scarcity) - individual has limited income
The marginal principle
Should pursue a choice or action up to the point where MB (additional benefit) is greater than or equal to MC (additional cost) net benefit= MB - MC (greater than or equal to zero)
Scarcity principle for consumers
The OC of consuming one more unit of a good (pizza) is the units of consumption of another good we must give up (pasta)
Scarcity principle for producers says
The OC of producing one more unit of a good (pizza) is the units of production of another good we must give up (pasta)
principle of comparative advantage
The party with the LOWER opportunity cost in producing a good should specialize in that activity - economic welfare may increase by people specializing and trading
Attainable point
any combination of goods that can be produced using currently available resources (either on our outside PPC)
Zone of Possible Agreement (ZOPA)
minimum asking price and maximum paying price
Efficient point
points that make use of all the avaliable resources in the economy to produce the maximum possible combo of goods (these points are on the PPC)
PPC downward sloping shape
represents the idea that to produce more of one good, we must give up another (due to scarcity)
