In Part I, I compared the statistical fact that non-farm employment was lower in September 2010 than it had been in December 1999 with the assertions that those who believed any such thing could occur were guilty of a lump-of-labor fallacy. In Part II, I rehearsed debating points regarding Paul Krugman's columns citing the alleged fallacy.
My intention in Part III is not to refute the fallacy claim. I believe I did that sufficiently in "Why Economists Dislike a Lump of Labor" and "The Lump-of-Labor Case Against Work-Sharing." To date, no one has brought forward a substantive rebuttal to those articles. Instead, I will explore further the evolution of the fallacy claim.
