1. Given that the current gasoline excise tax is computed by applying a per-gallon tax rate to each gallon and that a future vehicular user fee would be calculated by applying a per-mile fee to each mile, is there any economic distinction between a "tax" and a "fee"? Explain.
2. Why is there always a difference between static analysis and dynamic analysis of tax changes?
3. Why might people be willing to sacrifice dollars to avoid "feeling bad" about flouting tax laws?
