2018 AP Microeconomics FRQ #2

2018 AP Microeconomics FRQ #2

Watch me answer it here


(a) Identify the type of market failure illustrated by the graph. Explain.
The type of market failure is an Positive Consumption "Externality".

(b) Using the numbers on the graph, identify the market equilibrium price and quantity.

(c) Using the labeling on the graph, identify the area representing DWL at the quantity identified in part (b).
Part (b) is the equilibrium price of $6 and quantity of 16, the DWL at that quantity is EDF.

(d) Suppose the government is granting a subsidy to correct the market failure. What is the dollar value of the per unit subsidy to achieve the SOQ (Socially Optimal Quantity)?

(e) Suppose the government installs a price floor at $8,
(i) How many units will producers and consumers exchange? (8)
(ii) Does the Price floor correct the market failure?
NO, it actually makes it worse,, society would like 24 units consumed but after the price floor only 8 units are consumed.

Thou canst not vex me with inconsistent mind,
Since that my life on thy revolt doth lie.
O, what a happy externality do I find,
Happy to have thy love, happy to die!

Price Floors & Price Ceilings

Price Floors & Price Ceilings


Floors are High !

Say it again, Floors are High !

One more time, Floors are High !



A price floor is the lowest price that a supplier can charge for its good.

The price floor above is at $5, which mean that the $5 is the minimum price that the supplier can charge for its good. Governments often interfere in the market by passing laws that require producers (suppliers) to charge minimum prices. This price protects the suppliers in that no business can now charge less than the minimum price.
If a business decides to sell its good for less than the $5, the business owner might be fined or sent to jail.
Jacob Meged was a tailor of Polish descent who had a tailor shop at 138 Griffiths Street in Jersey City. He had a wife and four children and he needed money to feed his family.  Other tailors were charging 40 cents, but he wanted to get more business, so he put a sign in his shop window advertising that he would press suits for 35 cents. After all, this was America where you were accustomed to being free to charge what you want.  Beating the competition and being entrepreneurial was the American way, and he would be happy to press suits for 35 cents.  Unfortunately, Jacob didn’t get more business and instead, he was arrested.J. Raymon Tiffany, Special Assistant Attorney General in charge of enforcing NRA codes in New Jersey took responsibility for prosecuting the tailor. When Jacob Meged was read the charges, he told Judge Kinkead that he was only vaguely aware of the existence of a code, but he pled guilty to the charge that he had violated the New Jersey State Recovery Act.  Mr. Tiffany asked the court to impose a sentence stiff enough to warn other code violators that the law had teeth in it.
On Friday, April 20, 1934, Judge Robert V. Kinkead sentenced Jacob Meged to 30 days in the county jail, and he was ordered to pay a $100 fine.   At 40 cents a suit, Meged would have to press 250 suits to cover his fine.  That would be $100 he couldn’t use to feed his family, and in addition to this, he would lose a month’s earnings.
As The New York Times put it, “He believed that the codes were designed to help the ‘little fellow’ and could not believe that by charging 35 cents instead of 40 cents to press a suit would put him behind bars. In court yesterday he stood as if in a trance when sentence was pronounced.  He hoped that it was a joke.”
A price floor below the equilibrium point (market clearing price) is NOT  an effective or binding price floor.

Understand:
If the minimum price (price floor) is set below the equilibrium market clearing point it will have no effect as the market has already cleared.

Jung Sub: I don't get it.

Mr. Waugh: Picture this,, at the $3 price Jung Sub buys all the jars of pinto beans that I'm selling.
I'm happy and Jung Sub is happy. The market has cleared.
Then a government employee walks in the room and says that we can't sell beans for less than $1 per jar. The $1 minimum required price had no effect on the market (IT WASN'T EFFECTIVE), IT MADE NO DIFFERENCE.

2015 AP Microeconomics Exam FRQ #3

2015 AP Microeconomics Exam FRQ #3


Watch me answer it here

































(a) Calculate the total producers surplus at the market equilibrium price and quantity. 

Area of triangle   = (h * b/2)  or (1/2 height * base)

so, 20 (height) X 20 (base)/ 2 = 20*20 =400/2 = 200

Answer - 20*20 = 400/2 = 200 (total producers surplus)


AP - Answer - One point is earned for calculating the total producer surplus as (1/2 × 20 × 20) = $200.

(b) If the government imposes a price floor at $16, is there a shortage, surplus or neither?




















Remember (floors are high and ceilings are low). A price floor set below the equilibrium price will have no effect as the market will clear.

Answer - at a $16 price floor neither a surplus or a shortage will occur because the $16 is below the equilibrium price,, it is not an effective or binding price floor.

AP - Answer - One point is earned for stating that imposing a price floor at $16 is ineffective and will not create a surplus or a shortage in the market because it is set below the equilibrium price, or because it is not binding 

(c) If instead the government imposes a price ceiling at $12, is there a shortage, a surplus or neither? 

price ceiling is a government-imposed price control or limit on how high a price is charged for a product. 

So, the highest price that can be charged for the widgets is $12. At the low price of $12 suppliers will only provide 12 units of this good,, but at the low price of $12 people will demand 24 units. So there will be a shortage.
AP - Answer - One point is earned for stating that imposing a price ceiling at $12 will create a shortage because quantity demanded is greater than quantity supplied, or because the price ceiling is binding. 

(d) If instead the government restricts the market output to 10 units, calculate the deadweight loss.
Understand that a 10 unit restriction on output is represented by a perfectly inelastic supply curve at the 10 unit quantity. All the people/quantity to the right of the 10 unit limit will not be served/produced,, thus it is allocatively inefficient and therefore the efficiency is represented by deadweight loss. 

Area of Triangle = b*h/2

height = 40-10 = 30
base = 20-10 = 10

30*10 = 300/2 = 150

AP - Answer - One point is earned for calculating the deadweight loss as $150 and for showing:
(1/2 × 30 × 10) or
(1/2 × 10 × 10) + (1/2 × 20 × 10) or
$50 + $100 

(e) Assume the price decreases from $20 to $12.
(i) Calculate the PED
(ii) Is demand perfectly elastic, relatively elastic, unit elastic, perfectly inelastic or relatively inelastic?

Gonvernment Intervention 4 - Price Floors

Price Floors

Conversations welcome - Econowaugh's facebook

Remember (floors are high) - When drawing an effective price floor it must be drawn above the                                                         equilibrium.

Price floors are also known as minimum price, refers to setting a price higher than the market equilibrium by the government and no seller can sell the good at a lower price than the set minimum price.

Government reasons to set a price floor.
  • to protect the sellers and stabilize their incomes - agricultural products
  • to prevent deprivation for disadvantaged sellers - minimum wage
The graph above has a binding price floor that is set higher than the equilibrium price. This causes an excess supply of products. The high price causes the quantity demand to decrease allowing a glut or a surplus to form. The high prices help the producers (red area above) and hurts the consumer (blue area) as their surplus shrinks,,, the yellow triangle area is dead weight loss (DWL) or a loss to society in that these trades were not allowed to happen.

Impacts of a Price Floor

Conversations welcome - Econowaugh's Facebook

1.    Government measures to dispose of the surplus:

The price floor (high price) causes a surplus or excess supply. What's to be done with this excess. In some instances the government decides to buy the excess supply. The governments buying is described as actions necessary to keep the price high. The expense is financed by the taxpayer and incurs a loss to society.

Buffer stock schemes are not on the AP, (or I haven't found any examples) but the concept of the governments intervention and especially the effects are relevant.




2.     Producers gain and consumers loose:

Producers now receive a higher revenue than before, and are better off. However, consumers lose as they are forced to pay a higher price and (enjoy less of the products).

Venezuela Toilet Paper Shortage: Government To Import 50 Million Rolls 

3.      Loss of Social Welfare:

Less trade less goods and services being enjoyed. Therefore, the people are worse off.
Go back and look at the yellow triangle above.


4.      Inefficient Resource Allocation:

Since the government has started the program to buy the surplus of goods it stands to reason that producers to overproduce, causing inefficient resource allocation. (more resources, land, labor, will be used for producing the (government purchased good) and less for producing other goods.
