CALL FOR PAPERS Session(s) on Lionel Robbins Essay on the Nature and Significance of Economic Science after 75 Years HES 2007 AND ESHET 2007 In 1932, Lionel Robbins published a slim (less than 200 pages) but nonetheless "dangerous revolutionary document," as William Baumol has called it--his Essay on the Nature and Significance of Economic Science. A most influential economic treatise, the Essay helped to give birth to modern economics and contributed to the development of the scientific dimension of the discipline. Robbins not only proposed a definition of economics that seems to have helped pave the way for economic imperialism, he also criticized the claims that Welfare Economics could be scientific and argued that "economics," or economic science, should not be confused with "political economy." We propose to organize one or more sessions at the 2007 meetings of the History of Economics Society and the European Society for the History of Economic Thought to commemorate the 75th anniversary of the publication of Robbins' Essay. The papers should deal with some aspect of the writing, reception, impact, and diffusion of the Essay. Papers that examine how the Essay influenced economic thinking during the second half of the twentieth century are particularly encouraged. The 2007 History of Economics Society conference will take place June 8-11 at George Mason University in Fairfax, VA. The 2007 conference of the European Society for the History of Economic Thought will take place in July 5-8 in Strasbourg, France.
