Economics Discussion Questions

I need an explanation for this Economics question to help me study.

1. What is the difference between an excise tax and an ad valorem tax? Is the proposed tax on vaping products an excise or an ad valorem tax? What problem is the vaping tax aimed at addressing?

2. The article discusses the anticipated revenues from the vaping tax. If the tax is more effective than expected in addressing the problem mentioned in question 1 above, however, what implication would that have for government revenues from the tax?

3. What potential unintended consequence does the article suggest that a higher vaping tax might have? Can you imagine another distortionary effect a relatively high tax on vaping products might have specifically for people who live close to the border with another state? Explain.
