Lead-inReading critically: questions for discussion

Reading critically:Every text is written on a purpose, some are supposed to make you believe. It is important to learn to read critically to get the point. One way of training critical reading is to ask yourself the following questions:

Do you agree with the author?

What is the author assuming I will agree with?

What is the author trying to prove?

Lead-in

Reading critically: questions for discussion

Does the author adequately defend their argument?

What kind of proof do they use?

Is there something they leave out that you would put in?

Does putting it in hurt their argument?

Lead-inReading critically: questions for discussion

Discuss the following questions:

How do you make the decision that you take this course?

What do you consider when you make this decision?

Text AKey terms

rational people: 理性人 Those people who systematically and purposefully do the best they can to achieve their objectives, given the available opportunities.

marginal change: 边际变化 small incremental adjustments to a plan of action

marginal benefit: 边际效益 the additional benefit from an increase in an activity

Text AKey terms

marginal cost: 边际成本 the additional cost from an increase in an activity

marginal decision-making: 边际决策 the additional cost from an increase in an activity

incentive: 激励 something that induces a person to act

How People Make Decisions

Economists’ explanation about decision making: There are rules behind people’s decision-making behaviors.

Text ACritical reading and thinking

Rational people think at the margin.

Example 1: standby ticketsWhat a rational airline can do?

Situation: Flying a 200-seat plane across the U.S. costs the airline $100,000.

Cost of each seat: $500 (That’s to say, never sell a ticket for less than $500.)

Suppose: A plane is about to take off with 10 empty seats. A standby passenger will pay $300 for a seat.

Question: should the airline sell the ticket?

Answer: Yes.Reason: If the plane has empty seat, the cost of adding one more passenger is tiny. Here the marginal cost is merely the cost of something to eat, like peanuts, coco, etc.

Conclusion: As long as the standby passenger pays more than the marginal cost, selling the ticket is profitable.

Example 2: water vs. diamond

Why is water so cheap, while diamonds are so

expensive?

water diamond

Necessary for survival

The marginal benefit of an extra cup is small because water is plentiful.

Unnecessary for survival

The marginal benefit of an extra diamond is large because diamonds are rare.

Conclusion: Rational people think at the margin. (They make decisions by comparing costs and benefits.) Are you a rational person?

Example 1: the price of an appleHow people respond to incentives?

When the price rises: It provides an incentive for buyers to consume less; It provides an incentive for sellers to produce more.

Rational people respond to incentives.

Example 2: a tax on gasoline How people respond to incentives? Encourage people to □ drive small, more fuel-efficient cars; □ carpool □ take public transportation; □ live closer to where they work; □ drive hybrid cars; □ drive electric cars.

Example 3: a seat belt law

American laws require seat belts as standard equipment on new cars.

How a seat belt law alters a driver’s cost-benefit calculation (Peltzman’s analysis):Seat belts reduce the likelihood of injury or death → make accidents less costly → drive faster and less carefully → a large number of accidents

Result: These laws produce both fewer deaths per accident and more accidents. Conclusion 1: The net result is little change in the number of driver deaths and an increase in the number of pedestrian deaths.

Conclusion 2: When analyzing any policy, consider both the direct effects and less obvious indirect effects.

If the policy changes incentives, it will cause people to alter their behavior.

→ Rational people know that when they make a decision, it is often not a yes-or-no choice, but requires deliberate consideration of the pros and cons.

Text ADifficult sentences

Rational people know that decisions in life are rarely black and white but usually involve shades of gray. (Para. 2)

→ The most important theory in economic study concerns itself with incentives. Other theories are not as important. “The rest is commentary” is a phrase used in American English to mean “the rest is trivial or less important”.

“People respond to incentives. The rest is commentary.” (Para. 6)

→ At first, this discussion of incentives and seat belts might seem like random talk not supported by evidence.

At first, this discussion of incentives and seat belts might seem like idle speculation. (Para. 12)

New Airport Landing Fees Delayed

See Page 14, and do Task 1 and Task 2

Text BCritical reading

A new federal policy: allowing airports to charge higher landing fees during peak periods

Reason for formulating this policy: encourage airlines to arrange flights more evenly throughout the day, thus reducing flight delays

Costs Benefits

Airports

Airlines

Your reflections on this policy:

It will work:

It won’t work:

…, which last month called the proposal “congestion pricing disguised as an airport fee”. (Para. 13)

Text BDifficult sentences

→ …, which claimed that the proposal was actually charging fee for congestion rather than for the airport.

“Because the central policy issue at stake here – influencing airline market decisions through airport pricing – is inherently complex and historically has been controversial, we believe that it merits additional time to fully develop comments reflecting the views of industry stakeholders,” (Para. 14)

Text BDifficult sentences

→ “The central policy issue which is how to influence airline market decisions through airport pricing has always been complex and controversial. Hence it is necessary to allow more time for the parties involved in the industry to phrase their opinions that most clearly express their views.”

message. • Structure Organize your talk in a clear way and indicating or

showing the structure to the audience is very important and helpful to make an effective presentation because that makes comprehension easier.
