Today’s Between the Covers podcast is with Douglas Irwin, author of Peddling Protectionism: Smoot-Hawley and the Great Depression. We talk about whether the Republicans Reed Smoot and Willis Hawley are responsible for the Great Depression, how the politics of trade and protectionism have changed since then, and why so many liberal economists see the benefits of goods and services moving across borders.

And while we’re on the subject, don’t forget this classic movie moment: Ben Stein in Ferris Bueller’s Day Off.
