ECON 545
EXAM VERSION 3
(TCO A) Suppose you are hired to manage a small manufacturing facility that produces Widgets.
(a.) (15 points) You know from data collected on the Widget Market that market demand has recently increased and market supply has recently decreased. As manager of the facility, what decisions should you make regarding production levels and pricing for your Widget facility?
Remember that supply and demand are about the market supply and market demand, which is bigger than your own company. You are being given data on supply and demand for the whole market and are being asked what effect that has on you as a small part of that market.

1. The supply and demand schedules for tickets to basketball games in town of Oakwood are given in the table below.

Price 		Quantity Demanded 	Quantity Supplied
$6 			5,000			 2,000
7 			4,000 			2,000
8		 	3,000 			2,000
9 			2,000 			2,000
10 			1,000 			2,000
The stadium owners need to find the optimum price for the games.
1. What are the coefficients of elasticity of supply and demand if the price is raised from $6 to $8? (8 points)
Solution:
Coefficients of elasticity of supply and demand = (2,000/2) *(6/5000)
Where as 
2000 is Quantity Supplied at price of $6
5000 is Demand at price of $6
$8-$6 = $2
Coefficients of elasticity of supply and demand = (2,000/2) *(6/5000)
Coefficients of elasticity of supply and demand = (1,000*6/5000)
Coefficients of elasticity of supply and demand = = 1.2 (elastic)
2. Characterize the demand and supply for tickets based on the calculated elasticise. (4 points)

terms of fixed costs. Answer the next questions (Parts A and B) on the basis of the following cost 
data for John- firm operating in pure competition:
OUTPUT ------ TFC ---------- TVC

0                $30.00            0.00
1                 30.00            70.00

2                 30.00           120.00

4                 30.00           200.00

6                 30.00           360.00
(a.)	(15 points) Refer to the above data. If the product price is $60, at its optimal output, will the firm realize an economic profit, break even, or incur an economic loss? How much will the profit or loss be? Show all calculations.
(b.)	(15 points) Refer to the above data. If the product price is $55 at its optimal output, will the firm realize an economic profit, break even, or incur an economic loss? How much will the profit or loss be? Show all calculations. (Points : 30)
5. (TCO D)   A software producer has fixed costs of $20,000 per month and her Total Variable Costs (TVC) as a function of output Q are given below. Complete the table (TC, MC, TR, and MR), then answer Parts A and B.

  Q                        TVC                           Price
  2,000                $5,000                          $25    
  4,000                  7,000                            22    
  6,000                18,000                            20

10,000                50,000                              1    
(a.) (15 points) If software can only be produced in the quantities above, what should be the production level if the producer operates in a monopolistic competitive market where the price of software at each possible quantity is also listed above? Why? (Show all work.)
(b.) (15 points) What should be the production level if fixed costs rose to $70,000 per month? Explain.    
Question 6. 6. (TCO F)
(a.)	(20 points) Suppose nominal GDP in 1999 was $200 billion, and in 2001, it was $270 billion. The general price index in 1999 was 100 and in 2001 it was 150. Between 1999 and 2001, the real GDP rose by what percent?
(b.) Use the following scenario to answer questions (b1) and (b2). In a given year in the United States, the total number of residents is 270 million, the number of residents under the age of 16 is 
(b1.) (5 points) Refer to the data in the above scenario. What is the size of the labor force in the United States for the given year?
Question 7. 7. (TCO G and H)
7. (TCO G and H)   

(a.) (15 points) Suppose your local Congress representative suggests that the federal government should NOT intervene in the baseball ticket market to stop runaway price increases. Would you say that this view basically supports the Keynesian or the Monetarist school of thought? Why? What position would the opposing school of thought take on this issue? (Be brief -- you can answer this in 2 or 3 brief paragraphs). 
(b.) (10 points) Any change in the economy- total expenditures would be expected to translate into a change in GDP that was larger than the initial change in spending. This phenomenon is known as the multiplier effect. Explain how the multiplier effect works.  
(10 points) Explain how the Fed manipulates this rate in order to achieve macroeconomic objectives. (Points : 40)
Question 9. 9. (TCO E and I) Let the exchange rate be defined as the number of dollars per Japanese yen. Assume that there is a decrease in U.S. interest rates relative to that of Japan.
 (a.) (10 points) Would this event cause the demand for the dollar to increase or decrease relative 
to the demand for the yen? Why? 
Higher rates in Japan will cause money to come into Japan. The demand for Yen will rise and 
that of $ will fall relatively.  

(b.) (10 points) Has the dollar appreciated or depreciated in value relative to the yen? 
Higher demand for Yen will increase the exchange rate E. This implies $ has depreciated while 
Yen has appreciated.  

(c.) (10 points) Does this change in the value of the dollar make imports cheaper or more 
expensive for Americans? Are American exports cheaper or more expensive for importers of 
U.S. goods in Japan? Illustrate by showing the price of a U.S. e-reader in Japan before and after 
the change in the exchange rate. 

(d.) (10 points) If you had a business exporting goods to Japan, and U.S. interest rates fell as they
