Supporters of stronger intellectual property enforcement — such as those behind the proposed new Stop Online Piracy Act (SOPA) and Protect IP Act (PIPA) bills in Congress — argue that online piracy is a huge problem, one which costs the U.S. economy between $200 and $250 billion per year, and is responsible for the loss of 750,000 American jobs. 

These numbers seem truly dire: a $250 billion per year loss would be almost $800 for every man, woman, and child in America. And 750,000 jobs – that’s twice the number of those employed in the entire motion picture industry in 2010.

The good news is that the numbers are wrong — as this post by the Cato Institute’s Julian Sanchez explains. In 2010, the Government Accountability Office released a report noting that these figures “cannot be substantiated or traced back to an underlying data source or methodology,” which is polite government-speak for “these figures were made up out of thin air.”
