SECTION 1 SCARCITY, CHOICE, OPPORTUNITY COST

SECTION 1 SCARCITY, CHOICE, OPPORTUNITY COST

-People respond to incentives blank_______.

by ignoring negative incentives and responding to positive incentives only

only when they are irrational

by calculating their individual costs and benefits and determining which is greater

when they have low incomes

-After much consideration, you have chosen Cancun over Ft. Lauderdale as your Spring Break destination this year. However, Spring Break is still months away, and you may reverse this decision. Which of the following events would prompt you to reverse this decision?

The marginal benefit of going to Cancun increases.

The marginal cost of going to Cancun decreases.

The marginal benefit of going to Ft. Lauderdale decreases.

The marginal cost of going to Ft. Lauderdale decreases.

-A tradeoff exists between a clean environment and a higher level of income in that blank_______.

studies show that individuals with higher levels of income pollute less than low-income individuals

efforts to reduce pollution typically are not completely successful

laws that reduce pollution raise costs of production and reduce incomes

Bill discovers that he needs to do an additional $2400 of work to make the car worth $5800 to potential buyers. He could also sell the car now, without completing the additional work, for $3800. What should he do?

He should sell the car now for $3800.

He should keep the car since it wouldn’t be rational to spend $6400 restoring a car and then sell it for only $5800.

He should complete the additional work and sell the car for $5800.

It does not matter which action he takes since the outcome will be the same either way.
