In Paul Bairoch's Economics & World History - Myths and Paradoxes (1993), the very first myth he tackles is this:
the 1920s are generally described as being years of increasing protectionism.
I had never really heard of this "myth" before. But perhaps that is merely because Bairoch (1993) did such a good job at dismantling this myth. (My general impression had always been that it was in the 1930s that protectionism rose.)
So, is it true that before Bairoch (1993), economists "generally described" the 1920s "as being years of increasing protectionism"? Who were these economists and what exactly did they say?
