Challenge to Wanniski's Smoot-Hawley theory.

From Economic Principals, David Warsh claims a new book overturns Jude Wanniski’s Smoot-Hawley/Great Depression hypothesis.

From the archive, Wanniski explains his theory.

At his blog, Paul Krugman applauds Warsh.

From Econtalk last year, Thomas Rustici supports Wanniski’s view.
