others, not themselves. Under the coordination definition of economics:

• there still would be an economic problem.
• there would be a political problem but not an economic problem.
• there would be a social problem but not an economic problem.

• can eliminate scarcity.
• address the questions what is produced, how it is produced, and for whom it is

produced.

• provide equal distribution of well-being among its participants.

17) Scarcity exists because:

• new wants continue to develop and willingness to meet them is limited.

20) Alexandra has determined that studying an hour for her economics quiz will improve her grade on the quiz from a 75 to a 100. She also determines that this improvement is worth $20. To study for an hour for her economics quiz, however, she will have to work one fewer

hour at her part-time job. Alexandra should:

• study for the quiz as long as her hourly wage rate is less than $20.
• study for the quiz as long as her hourly wage rate is more than $20.
• study for the quiz only if her hourly wage rate is exactly $20.
• not study for the quiz because earning a higher grade cannot have a dollar value.

21) Microsoft filed a lawsuit against people who sent spam (junk email) and a website owner who hosted spam services. A spokesman for Microsoft said that Microsoft was "trying to change the economics of spam" by increasing the cost of being a spammer. An economist most likely would agree with which statement about Microsoft's actions?

• A more effective approach would be to educate spammers about the costs they

impose on others.

• A more effective approach would be to appeal to the morals of the spammers and tell

them to follow the Golden Rule.

• Microsoft's approach of trying to change the costs of spamming is the most efficient

way to change behavior.

• Microsoft should not be involved because spamming is just part of the invisible hand

at work and should be left alone.
