Copyright protection grants creators monopolies – with their attendant harms – in order to provide incentives for continued creation. File sharing, which exploded with Napster’s appearance in 1999, effectively weakened copyright protection. Researchers have documented depressing effects of...

Scholars working on the border of economics and psychology have assembled an impressive body of evidence that consumer behavior is not fully rational. As a result some observers (see Kahneman, 1994) question whether consumer choice warrants deference. We address this question by asking whether...

Recent literature notes that when quality is produced with fixed costs, a high quality firm can undercut its rival's prices and may find it profitable to invest more in quality as market size grows large. As a result, a market can remain concentrated even as it grows large. When quality is...
