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
