In today's New York Times' Economic Scene column, Hal R. Varian discusses the
lack of intellectual property in the fashion industry, and cites the outstanding work of Kal Raustiala and Chris Sprigman. They have been a two-man intellectual demolition crew on IP in fashion goods. Their work on the
piracy paradox is a must read.
He rightly notes that if lawyers called the fashion tune, fashion would become "boring, boring, boring." Not to mention more scarce and expensive.
Unfortunately, he goes off the rails a bit in claiming that the lack of copyright in America for foreign authors hurt the book trade. In fact it promoted the growth of literacy, and the development of the book industry and an American authorial class.
Hal R. Varian wrote a paper
"Copying and Copyright" in which he noted that some authors made more money from their non-copyrighted books than from those that were copyrighted.
