I would recommend two books--one old, one fairly new.
The first is W.H.Hutt's ECONOMISTS AND THE PUBLIC (Jonathan Cape, 1936),
especially chapter XIV "Sanctions for the Economists' Authority."
The second is Michael A. Bernstein's A PERILOUS PROGRESS:ECONOMISTS AND
PUBLIC PURPOSE IN TWENTIETH-CENTURY AMERICA (Princeton University Press,
2001). A quick summary of the main arguments is found in my review of this
book in THE QUARTERLY JOURNAL OF AUSTRIAN ECONOMICS 6:1 (Spring 2003),
75-79. This review should be available online at www.mises.org in the
journals section.
