7. Which of the following is NOT one of the results of a tariff?

B. The domestic quantity demanded falls.

C. The total gains from trade rises.

D. The amount of imports falls.

8. A tariff is a tax that consumers pay to the government. What impact does the act of paying this tax have on total gains from trade?

A. It reduces total gains from trade because consumer surplus falls as a result of the tax payment.

B. It has no impact because tariffs are also paid by producers, so the two payments cancel each other out.

C. It has no impact because the gains from trade are transferred from consumers to the government.

D. It increases total gains from trade because the government earns tax revenue.

9. As a result of a tariff, domestic consumption _______, and this causes total gains from trade to _______.

Use the table and graph to answer three questions.

Using the table and graph answer the questions

a. What is the equilibrium price level?

b. What is the equilibrium output?

In what ways are tax inversions beneficial to both the United States and the host country of the inversion?

Describe the Horizontal Merger Guidelines used by the Federal Trade Commission (FTC) and the Antitrust Division of the U.S. Department of Justice (DOJ) to prevent firms from merging into a single firm.

In the case of Allergan and Pfizer, there are two sovereign powers in play - Ireland and the United States. Why was Ireland interested in letting the inversion take place, and why was the U.S. government against the inversion? IS the decision by the United States a direct affront to the sovereignty of Ireland?

3. b. What effect does the change of the exchange rate have on net exports
4. c. How do the combined changes in consumption, investment, and net exports affect the AE curve and the AD curve
5. d. Suppose that prior to the increase in the money supply, equilibrium GDP was equal to potential GDP. What type of output gap now exists? If potential GDP does not increase, what will happen to equilibrium GDP in the long run?
6. e. Based on your answers above, can expanding the money supply drive long-run growth? What is this relationship called?

The town of Cypress Creek is preparing to go to war against the American government. To do this, it is building a giant satellite laser! To build the laser, the government of the town will resort to taxation to fund its expenditure. The initial economy of Cypress Creek can be expressed by the following agents:

Consumers, C = 25 + 0.95(Y-T)

Output, Y = 5000

Government expenditures, G = 2000

Taxation, T = 2000

Investors, I = 750-125r

Markets are fully competitive and the equilibrium condition for markets are:

Goods and service market: Y =C + I + G

Financial market: I = S

When it builds the Satellite, government and taxation change to  

Government expenditures, G = 4000

Taxation, T = 4000

Hank Scorpio, the towns' founder, announces that "even by increasing government spending and taxation, we are not worst off, as production has not changed!"

1. [2 points] check to make sure output does not change.
2. [2 points] find the consumption level in both scenario's (low and high government spending).
3. [3 points] who is paying for the burden of taxation? (how is this new spending/taxation being distributed between investors and consumers)
4. [2 points] as the government increases its spending (G from 2000 to 4000) why won't output change?

Hank Scorpio makes another announcement "People of North Haverbrook! We must all work together in this to crush the American Government - I implore you to save you wages! Don't spend!"

13. [2 points] by how much would consumers need to reduce their Marginal propensity to consume (MPC) such that the market clearing interest rate does not change?  

What was the gold standard? How is monetary policy conducted under a gold standard? What are the virtues of a gold standard, according to Meltzer? What would be a shortcoming of a gold standard?

Consider the following three models that a researcher suggests might be a
reasonable model of stock market prices
yt = yt−1 + ut
yt = 0.5yt−1 + ut
yt = 0.8ut−1 + ut
(a) What classes of models are these examples of?
(b) What would the autocorrelation function for each of these processes look
like? (You do not need to calculate the acf, simply consider what shape it
might have given the class of model from which it is drawn.)
(c) Which model is more likely to represent stock market prices from a
theoretical perspective, and why? If any of the three models truly
represented the way stock market prices move, which could potentially
be used to make money by forecasting future values of the series?
(d) By making a series of successive substitutions or from your knowledge of
the behaviour of these types of processes, consider the extent of
persistence of shocks in the series in each case.
