Q

About 540 million passengers took plane trips in the United States in 2012. Since the 9/11 hijackings, security screening has become more intensive, and consequently, the procedure takes one hour longer than in the past. If the average price of time for air travelers is $25 per hour, the ____________ of delay in airports is 540 million hours × 25 dollars/hour, or $13.5 billion per year.

Q

In economic decision making, sunk costs are

A

irrelevant in choosing among different options.

31
Q

When only knowing that both the demand curve and supply curve shift and nothing else, it is

A

possible to determine to what happens to either equilibrium price or the equilibrium quantity but not both.

32
Q

After widespread press reports about the dangers of contracting “mad cow disease” by consuming beef from Canada, the likely economic effect on the U.S. demand curve for beef from Canada is:an

A

an inward shift of the demand curve for beef.

33
Q

At the market equilibrium

A
  • all the market participants who are willing and able to participate at the market price either buy or sell all that they wish.
    -there is no shortage or surplus
    -quantity demanded equals quantity supplied

ALL OF THE ABOVE

34
Q

A change in price of a pretzels typically causes ___ for those pretzels.

A

a change along the supply curve

35
Q

The framing effect

A

should be avoided in economic decision making

36
Q

A fixed cost is one that

A

remains constant while output changes.

37
Q

The tendency for the quantity supplied to be higher when the price is higher is the

A

Law of Supply

38
Q

Last semester in the bookstore, no one had any trouble getting a microeconomics textbook from the bookstore when the price was $40, and the bookstore had no books unsold. This semester, even though more textbooks were ordered, the bookstore ran out of microeconomics textbooks when the price was $45. This indicates

A

the price of $45 was too low.

39
Q

When the marginal cost exceeds the marginal benefit of an extra unit

A

net benefit falls.

40
Q

A market equilibrium maximizes

A

consumer surplus plus producer surplus.

41
Q

Draw the graph showing what should happen to the equilibrium price and equilibrium quantity of downloadable classic rock music recordings when the price of CDs falls.

A

CDs are substitutes for downloadable music, so when the price of a substitute good falls, the demand for the primary good drops.

42
Q

Cell phones are a substitute for CDs,

A

so a reduction in the price of cell phones should reduce the demand for classic rock CDs.

43
Q

this reduces the equilibrium price and equilibrium quantity of classic rock CDs

A

all other things equal

44
Q

An increase in productivity in the CD industry

A

increases the supply of CDs by lowering the costs of production

45
Q

this reduces the equilibrium price and increases in the equilibrium quantity.

A

when all things equal

46
Q

Since both effects reduce the equilibrium price, it is clear the equilibrium price for classic rock CDs must

A

fall

47
Q

insufficient information to determine the actual outcome for

A

the effects have opposite influences on the equilibrium quantity

48
Q

EX = -0.74 which suggests that

A

the two goods are complements.

49
Q

An elastic response means that

A

the dependent variable changes proportionally more than the independent variable

50
Q

Along a linear demand curve, the price elasticity of demand

A

changes.

51
Q

An effective market impediment

A

causes a deadweight loss.

52
Q

An underlying precept of microeconomics is…

A

People are the best judge of their interests.

People respond to incentives.

53
Q

What is the economic surplus generated by a decision calculated?

A

It is the total benefits minus total costs arising from the decision.

54
Q

Marginal thinking refers to

A

looking at deviations from the status quo

55
Q

Cost is..

A

what is given up in obtaining something.

56
Q

Following the Rational Rule, the maximum economic surplus occurs when:

A

marginal benefits equal marginal costs.

57
Q

Opportunity Cost is

A

the value of something in its next best use.

58
Q

Ron is buying jeans online and is deciding how many to buy. Applying the Rational rule, he will buy an additional pair if the:

A

marginal benefit of the next pair is at least as high as the price of the jeans.

59
Q

The Law of Diminishing Marginal Returns States…

A

a. indicates that after a point, marginal benefits decline with each additional unit.

b. indicates that after a point, marginal costs increase with each additional unit.

c. gives assurance that marginal benefits and marginal costs usually will end up equal at a point.

60
Q

Ignoring opportunity cost in economic decision making

A

reduces net benefits.

61
Q

Marginal cost (MC) is,

A

the cost of obtaining one more unit.

62
Q

The rational rule is

A

a) act to maximize the economic surplus.

b) act to maximize the total benefits minus the total costs.

c) act so that MB = MC.

63
Q

The framing effect

A

Should be avoided in economic decision making.

64
Q

Quantity demanded (QD) is

A

the amount people are able and want to purchase

65
Q

A normal good is one that,

A

anything unless told so

66
Q

Quantity supplied is

A

the amount a producer is willing and able to sell

67
Q

the market demand curve shows

A

the amount consumers are willing and able to buy at various prices during a specific period of time

68
Q

The law of supply indicates as price falls

A

so does the quantity supplied

69
Q

At the market equilibrium,

A

a. all the market participants who are willing and able to participate at the market price either buy or sell all that they wish.

b. there is no shortage or surplus

c. quantity demanded equals quantity supplied

70
Q

A surplus

A

occurs when QS>QD

70
Q

All other things equal, an increase in price causes

A

quantity supplied to rise

71
Q

In a competitive market where the price of the product is $25, we know that marginal cost of the last unit sold is

A

equal to $25

72
Q

When only knowing that both the demand curve and supply curve shift and nothing else, it is

A

possible to determine to what happens to either equilibrium price or the equilibrium quantity but not both.

73
Q

All other things equal, a decrease in quantity demanded refers to

A

a movement down the demand curve
