Discussion Questions:

• Given that knowledge is non-rival--if I teach it to you, I don't have any less of it than I did before--what justification could there possibly be for charging people for access to knowledge and its uses?
• If people weren't allowed to charge others for access to knowledge and its uses, would there be any reason to think that society would be putting a properly-large share of our resources into creating and disseminating knowledge?
• Why can contests and the rule of priority be good ways to spur the creation and dissemination of knowledge?
• How well do contests and the rule of priority fit with a private-property market economy?
