Precisely how the MPAA cooks the books on piracy losses

The Cato institute's dug deep into the MPAA's funny piracy accounting: "In IPI-land, when a movie studio makes $10 selling a DVD to a Canadian, and then gives $7 to the company that manufactured the DVD and $2 to the guy who shipped it to Canada, society has benefitted by $10+$7+$2=$19. Yet some simple math shows that this is nonsense: the studio is $1 richer, the trucker is $2, and the manufacturer is $7. Shockingly enough, that adds up to $10. What each participant cares about is his profits, not his revenues."
