2. Suppose Mr. Carson has three footmen: Thomas, Alfred and Jimmy. There are two jobs that need to be done at Downton Abbey this week: (1) polishing shoes and (2) mending vests. Each footman works a total of 60 hours this week. Suppose the following information summarizes their individual production functions. Assume all values are completely divisible.
|Time it takes to |Thomas |Alfred |Jimmy |
|Polish a pair of shoes |2 hours |5 hours |15 hours |
|Mend a vest |1 hour |10 hours |3 hours |
a. Graph the individual PPFs for each of the three footmen.
b. Find each footman’s marginal opportunity cost for polishing a pair of shoes.
c. Suppose that Mr. Carson has each footman splitting his time evenly between the two tasks. Identify each footman’s production point on your graphs in part (a). How many pairs of shoes and vests is each footman doing? And how many pairs of shoes and vests, in total, are being polished and mended at Downton?
d. Mrs. Hughes comes along and suggests to Mr. Carson that he is being terribly inefficient in his allocation of tasks. Demonstrate using an efficient joint production possibility frontier that Mrs. Hughes is correct! Show us where Mr. Carson’s aggregate production point is in your efficient joint production possibilities frontier.
IN ALL GRAPHS PUT PAIRS OF SHOES ON THE HORIZONTAL AND NUMBER OF VESTS ON THE VERTICAL. Thanks!

3. Consider the very simple closed economy of HappyLand. Only four goods are produced in HappyLand: pizza pies, cheese, cars and wine. There is no government, and no international sector.
Note the following very important information:
i) Pizza pies, cars and wine are final goods and final goods only.
ii) Cheese is consumed as a final good AND it is used as an intermediate good by firms in the production of pizza pies.
iii) Each pizza pie made uses up 1/2 pound of cheese.
|Item |Price |Quantity in 2010 |Price in 2012 |Quantity in 2012| | | |
| |in 2010 | | | | | | |
|Pizzas |$20 |100 |$25 |150 | | | |
|Pies | | | | | | | |
|Cheese |$4 |600 |$3 |700 | | | |
|Cars |$10000 |45 |$12000 |50 | | | |
|Wine |$20 |400 |$25 |500 | | | |
The table provides ALL the information you need to know on prices and total output/production for the purposes of calculating national income statistics. Some work space is also provided.
SHOW YOUR WORK FOR EACH PART!
a. Calculate nominal or current GDP in year 2010.
b. Calculate nominal or current GDP in year 2012.
c. Calculate real GDP in 2012 assuming 2010 is the base year.
d. How, specifically, as an economist would you address the following questions posed to you by a TV news reporter? “Is HappyLand a strong and very happy place to live? Are the citizens of HappyLand doing better in 2012 than in 2010 and do they have a high standard of living?”
e. What is the implicit GDP deflator index in 2012, assuming 2010 is the base year?
f. Calculate how much inflation there was between 2010 and 2012 according to the implicit GDP deflator index, using 2010 as the base year.
g. Suppose Harry, who lives in HappyLand, has a brother named Charles. Charles graduated from college in 2010 and was given a gift of $10,000 from his grandmother. Harry is graduating in 2012. This same grandmother intends to give him $10,000 as well. Harry feels this is not fair. He thinks he should get more. Can you use the information from this problem to defend Harry’s position? In fact, how much would you suggest grandma give Harry so that the gifts seem more equal?

-----------------------
[i]. C. Charlie, since his MOC to make corndogs is 3 bananas, the highest of all. So use him to make corndogs last.
[ii] E. J has a positive sign, so as J increase, quantity demanded increase. This does not apply to: number of firms making jelly beans (affect supply, not demand), price of jelly beans (should be reverse relationship by LoD), nor the Easter basket (complimentary good). Price of sugar is production cost so doesn’t affect demand. So only E is correct.
[iii] E. When the cost of producing chairs increases, production cost increases drops, resulting in a decrease in supply. Answer A is wrong because a change in the price will result in a change in the quantity supplied, not the supply. Answer B is wrong because a higher income will change demand but not supply. Answer C is wrong because it results in an increase in supply. Answer D is wrong because a change in the price will result in a change in the quantity supplied, not the supply.
[iv] C. Part A is incorrect. A decrease in the price of corn (a substitute in consumption for green beans) causes people to consume more corn, and buy less green beans instead (since green beans are now relatively more pricey, compared to corn). Therefore, this event causes the demand curve for green beans to shift to the left. The supply curve remains unchanged. As a result, the equilibrium price and the equilibrium quantity will both decrease. Part B is incorrect. The new bean-eating worm causes the production costs of green beans to increase-shifting the supply curve of green beans to the left. The demand curve remains unchanged. As a result, the equilibrium quantity must decrease, and the equilibrium price must increase. Part C is correct. The fall in the price of butter causes people to buy more butter, and hence buy more green beans as well (since they are complementary goods). As a result, the demand curve of green beans shifts to the right. Furthermore, bean farms are protected from blight; hence, the supply curve shifts to the right. As a combined result, the equilibrium quantity must increase. We cannot tell what happens to the equilibrium price- this depends on the relative sizes of the shifts of the demand and the supply curves. Part D is incorrect. Wet harvest conditions shift the supply curve to the left. The new medical survey about the life benefits of green beans shifts the demand curve to the right. As a combined result, the equilibrium price must increase. We cannot tell what happens to the equilibrium quantity, without knowing the relative sizes of the shifts of the curves. The equilibrium quantity might increase or decrease, we do not know. Part E is incorrect. The expectation of lower bean prices in the future shifts the demand curve to the left. The supply curve remains unchanged. As a result, both the equilibrium quantity and the equilibrium price must decrease.
[v] E. The binding quota on Brazilian sugar means that the price in the market will be determined by the demand curve: i.e. consumers will be paying their maximum willingness to pay at the quantity determined by the quota. Because demand curves slope down, this price will be higher than what consumers were previously paying for Brazilian sugar. American and Brazilian made sugar are substitutes. An increase in the price of Brazilian sugar increases the demand for domestically made sugar. Therefore, the demand curve for American made sugar shifts out and to the right, increasing the equilibrium market price and quantity of American sugar. Altogether, the price of both Brazilian and American made sugar increases.
[vi] C.
[vii]. E. A and B are good examples of intermediate goods. C counts as GDP of China. D, the used textbook counts as GDP of the year it was made.
[viii]. C. GDP is what is produced in the country. GNP is what’s produced by your country’s people. So Francine’s work counts towards the UK’s GDP but not its GNP and her work counts toward the France’s GNP but not its GDP.
[ix]. E. Since you donated them, they did not go through a market so would not be counted in GDP.
[x]. C. CPI tends to overstate inflation as CPI computation uses base year bundle. Implicit GDP Deflator Index (IGDPDI) tends to understate inflation.
[xi]. C. Structural unemployment: the portion of unemployment that is due to changes in the structure of the economy that result in a significant loss of jobs in certain industries. An introduction of new technology in production process could be a cause of structural unemployment.
[xii]. B. Find the answer or in PowerPoint for Lecture 8.
[xiii]. A. Last week, the unemployment rate was 10,000/(10,000+90,000)*100=10%. This week, the unemployment rate is 12,000/(12,000+90,000)*100=…%. Therefore, the unemployment rate increased since last week, as a result of 2,000 people entering the labor force.
