Opportunity Cost (2 pts.)
Your friend is preparing for an exam and in the review session makes the following statement: "Instead of
attending microeconomics class for two hours, Kiki could have played tennis or watched a movie.
Therefore, the opportunity cost of attending class is the tennis and the movie she had to give up." Is your
friend's analysis correct or not? Explain your answer.
2. Incentives (2 pts.)
Consider the following summary of a
The number of people involuntarily bumped off flights bounced up more than 40% to 185,368 in
the second quarter, compared with the same period in 2005, according to government data.
Also, the number of passengers enticed to voluntarily give up seats on overbooked flights
rose more than 10% in the second quarter over last year." The reason for the increase in
overbooked flights: Higher fuel prices. With the increased marginal cost of flying planes,
airlines have cut back on the number of flights, thus jamming more people onto remaining
trips. Furthermore, airlines have the financial incentive to overbook flights. "The DOT requires
that airlines compensate passengers for bumping them off flights, but the maximum amount of
$400 was set in 1978 and hasn't changed. Had the maximum amount been adjusted for inflation,
it would be more than $1,200 today. And some argue that since the last tickets sold are usually
more expensive, airlines have too much incentive to sell $1,000 tickets when no seats are
available if the penalty is only $400 to bump a cheaper-fare passenger.
