(Exhibit: Markets and Efficiency) In panel (a): 
Question 22 options:
the price of apples is $0.80 and   the quantity demanded is Q1.

the equilibrium price ensures that   there will be neither surpluses nor shortages. 
all of the above are   true.

Question 23 options:
less than $0.80. 
equal to $0.80. 
greater than $0.80. 
equal to the average cost of   producing apples. 
Question 24 (5 points)
(Exhibit: Markets and Efficiency) The price and marginal cost in Panel(a) are equal because of: 
Question 24 options:

Question 25 (5 points)
(Exhibit: Markets and Efficiency) What is the marginal benefit to a producer of an extra pound of apples in Panel (a)? 
Question 25 options:

It is the price the consumer   receives. 
It is the price the producer pays.   
It is all of the above. 
Question 26 (5 points)
(Exhibit: Markets and Efficiency) What is the marginal cost of an extra pound of apples to a producer in Panel(a)? 
Question 26 options:
It is greater than the price. 
It is the value that   must be given up to produce an extra pound of apples. 
It must be less than the price. 
It is the cost of the least satisfactory   apples. 
Question 27 (5 points)
(Exhibit: Markets and Efficiency) In Panel (b) demand shifted from D1 to D2, reflecting a change in consumer preferences. The price of apples will change to the new equilibrium price: 
Question 27 options:
where the marginal benefit of   apples is again equal to the marginal cost. 
of $0.70. 
where an efficient solution is   again achieved. 
that is described by   all of the above. 
Question 28 (20 points)
What effect on the price elasticity of demand for commuter rail is there likely to be from a decrease in the price of gasoline? Explain your answer.
Decrease in price of gasoline will increase use of personal vehicles as people will find it cheaper and more comfortable to use personal vehicle. Personal vehicles and commuter rails are substitutes. Increase in use of personal vehicles will reduce demand for commuter rail. Price of ticket of commuter rail does not vary with shirt-term fluctuations in the price of gasoline. So in short-term, demand for commuter rail will decrease. If price of gasoline remains low for long time, ticket price of commuter rail will fall and so demand for commuter rail will increase. 
The quantum of impact of change in price of gasoline on the demand of commuter rail is determined by cross-price elasticity of demand of commuter rail with respect to the price of gasoline. Cross-price elasticity between gasoline price and demand for commuter rail is about 0.2 (Nowak & Savage, 2013). So, change in price of gasoline will have small impact on the demand for commuter train. Positive cross-price elasticity shows that decrease in price of gasoline will lead to decline in demand for commuter train. For every 1% decrease in price of gasoline, demand for commuter train will decline by 0.2%.
