Which of the following quantities decrease in response to a tax on a good? A. the equilibrium quantity in the market for the good, producer surplus, and the well-being of buyers of the good B. the equilibrium quantity in the market for the good, the effective price of the good paid by buyers, and consumer surplus C. the effective price received by sellers of the good, the wedge between the effective price paid by buyers and the effective price received by sellers, and consumer surplus D. None of the above is necessarily correct unless we know whether the tax is levied on buyers or on sellers.
A. the equilibrium quantity in the market for the good, producer surplus, and the well-being of buyers of the good
Suppose a country called Eutopia only produces two goods: pencils and cups. In 2014, it produces 10 pencils and 4 cups, in 2015 it produces 14 pencils and 6 cups. Prices in 2014 for pencils and cups are $2 and $2, and are $3 and $4 in 2015. Also, the consumer basket is chosen by the official in Eutopia as 2 pencils and 3 cups, while the base year is chosen to be 2014. What is the CPI for Eutopia in 2015? A. 10 B. 1.8 C. 18 D. 1.65
B. 1.8 Following the steps we discussed in class to get CPI. As can be seen the consumer basket is given to you, as well as prices for different years. Then, The CPI basket expenditure for base year 2014 is $2*2+$2*3 = $10 The CPI basket expenditure for 2015 is $3*2 + $4*3 = $ $18 Therefore, CPI for 2015 is $18/$10 = 1.8 (or 180 if multiplied by 100 but it is not provided in the question) If you get 1.65... it is probably the GDP deflator_2015 = Nominal GDP2015/Real GDP2015 = (14*$3+6*$4)/ (14*$2+6*$2) = $66/$40 = 1.65. (or 165 if multiplied by 100 using the definition from textbook). I intentionally put the information in the first paragraph to distract you... in fact if you see you need to calculate CPI, the only things you care are the consumer basket and prices, and you can definitely ignore the output information unless you are asked to calculate GDP deflator or nominal/real GDP.
Suppose that an economy produces 20,000 units of good A which sells at $3 a unit and 40,000 units of good B which sells at $1 per unit.

Which of the following is true of markets characterized by positive externalities? A. Social value exceeds private value, and market quantity exceeds the socially optimal quantity. B. Social value is less than private value, and market quantity exceeds the socially optimal quantity. C. Social value exceeds private value, and market quantity is less than the socially optimal quantity. D. Social value seldom exceeds private value; therefore, social quantity is less than private quantity.
C. Social value exceeds private value, and market quantity is less than the socially optimal quantity. With positive externality, the goods will be under-supplied, i.e. the market quantity is less than the socially optimal quantity. That is why government subsidizes the demand or supply side in the market
In a market economy, government intervention A. will always distort market outcomes. B. reduces efficiency in the presence of externalities. C. may improve market outcomes in the presence of externalities. D. is necessary to control individual greed.

C. the GDP deflator but not the CPI Explain: US army expenditure (national defense) is part of government spending, which is included in GDP calculation as well as GDP deflator. However it is not in the consumer basket (as indicated by the question) so it will not change CPI. It is a question from our textbook.
GDP is defined as the A. value of all goods and services produced within a country in a given period of time. B. value of all goods and services produced by the citizens of a country, regardless of where they are living, in a given period of time. C. value of all final goods and services produced within a country in a given period of time. D. value of all final goods and services produced by the citizens of a country, regardless of where they are living, in a given period of time.
C. value of all final goods and services produced within a country in a given period of time.

C.900 Therefore V_today = (V_1980 * CPI_today)/ CPI_1980 =$600*300/200 =$900
An American buys a pair of shoes manufactured in Italy. How do the U.S. national income accounts treat the transaction? A. Net exports and GDP both rise. B. Net exports and GDP both fall. C. Net exports are unchanged, while GDP rises. D. Net exports fall, while GDP is unchanged.
D. Net exports fall, while GDP is unchanged. Recall Y = C + I + G + NX = C + I + G + (X-M). Here import increase, M goes up, and this makes NX (net export) goes down. Also consumption C increase. These two change have exactly the same amount with opposite direction, therefore D is correct.

Which of the following does NOT add to U.S. GDP? A. Air France buys a plane from Boeing, the U.S. aircraft manufacturer. B. General Motors builds a new auto factory in North Carolina. C. The city of New York pays a salary to a policeman. D. The federal government sends a Social Security check to your grandmother.
D. The federal government sends a Social Security check to your grandmother. Explain: the last one is an example for government transfer payment, as I mentioned in class. A the air plane is manufactured in US (seems Boeing do not have oversea factories) so it is a part of US net export (actually export).
Which of the following statements is correct? A. Real GDP cannot be equal to nominal GDP because the former controls the price level change (inflation). B. GDP per capita is as good as GDP when measuring the standard of living in an economy since both measure the wealth created by this country. C. To increase standard of living in a country, the best way is to encourage people to work more by subsidizing. D. There could be some difference between income and expenditure ways calculating GDP due to statistical discrepancy.
D. There could be some difference between income and expenditure ways calculating GDP due to statistical discrepancy. So as we talked about in class, increase labor productivity is important to increase real GDP per capita, and investing on research or education is needed due to this, rather than persuade people to work more.

The supply curve and demand curve expressions in a good market is given as: 12 = Qs and P = 10 - Qd. What will the quantity sold/bought in this market? (Hint: draw a graph if you can) A. 12 B. 10 C. 0 D. -2
c. 0 This is a little tricky. You might end up wondering the result you get is Q*=12 and P* = -2 using the techniques we talked about in class. BUT always remember values for P and Q can NEVER be negative in our discussion (they can only be in the first quadrant and its boundary), so this is actually NOT a reasonable market equilibrium solution.
In a market economy, supply and demand are important because they a. play a critical role in the allocation of the economy's scarce resources. b. determine how much of each good gets produced. c. can be used to predict the impact on the economy of various events and policies. d.

Which of the following might cause the demand curve for an inferior good to shift to the right? a. an decrease in the price of a substitute b. an increase in the price of a complement c. an increase in income d. None of the above is correct.
d. None of the above This is a tricky question. The substitute/complement relationship still holds for inferior good, and notice the direction of demand curve shifting when income changes. Therefore, none of A, B or C is correct.
A price ceiling is a. often imposed on markets in which "cutthroat competition" would prevail without a price ceiling. b. a legal minimum on the price at which a good can be sold. c. often imposed when sellers of a good are successful in their attempts to convince the government that the market outcome is unfair without a price ceiling. d. None of the above is correct.
d. None of the above Government want to impose price ceiling probably because the price is too high. A market price higher than competitive equilibrium price is caused by possibly strong market force on the supply side (lack of competition, think about Microsoft), but rather what option A has said. Option B is the definition of price floor. Also, notice that seller do not want a binding price ceiling which will give them a lower price compared to scenario without a price ceiling, hence C is wrong.
