Economic Questions and IssuesEconomic Questions and Issues

1. Is Powerball a “bad” investment?

2. Is it irrational to play powerball?

3. Who plays powerball?

4. What is the state’s objective?

5. As a matter of policy, is it a good idea to use lottery gambling as a major revenue source?

6. Are there “hidden” costs?

Let’s think about this…

• Government sells Powerball tickets ($1 each)

• Ordinary citizens buy tickets

• Most Citizens receive nothing from govt. directly in terms of monetary gain

• Money used in government programs (state parks, schools, etc.)

This sounds like it could be a…

a TAX!!!

Regressive tax: tax rate (%)

gets higher as income gets lower –

the poor pay relatively more

So what kind of tax could be?

Progressive tax: tax rate (%) gets

higher as income gets higher (e.g., US

personal income tax) –

the rich pay relatively more
