Economist: A tax is effective if it raises revenue and burdens all and only those persons targeted by the tax. A tax is ineffective, however, if it does not raise revenue and it costs a significant amount of money to enforce.

Summary

If a tax raises revenue and burdens only people targeted by the tax, then then tax is effective. If a tax does not raise revenue and it costs a significant amount of money to enforce, then the tax is ineffective.

Strongly Supported Conclusions

If a tax is ineffective, then it either does not raise revenue or it does not burden all and only people targeted by the tax.

A
The tax on cigarettes burdens most, but not all, of the people targeted by it. Thus, if it raises revenue, the tax is effective.

This answer is unsupported. This answer fails one of our sufficient conditions for a tax to be considered effective. We need both of the sufficient conditions in order for a tax to be considered effective.

B
The tax on alcohol raises a modest amount of revenue, but it costs a significant amount of money to enforce. Thus, the tax is ineffective.

This answer is unsupported. This answer fails one of our sufficient conditions for a tax to be considered ineffective. We need both of the sufficient conditions in order for a tax to be considered ineffective.

C
The tax on gasoline costs a significant amount of money to enforce. Thus, if it does not raise revenue, the tax is ineffective.

This answer is strongly supported. It meets both of our sufficient conditions we are given for a tax to be considered ineffective.

D
The tax on coal burdens all of the people targeted by it, and this tax does not burden anyone who is not targeted by it. Thus, the tax is effective.

This answer is unsupported. There are two sufficient conditions to be met in order for a tax to be considered effective. This answer only satisfies one of the two sufficient conditions.

E
The tax on steel does not cost a significant amount of money to enforce, but it does not raise revenue either. Thus, the tax is ineffective.

This answer is unsupported. This answer fails one of our sufficient conditions for a tax to be considered ineffective. We need both of the sufficient conditions in order for a tax to be considered ineffective.
