Traces of the Veblen-Hoover "convergence" noted by Mayhew may also be found in the work of other American institutionalists such as Allyn Young.  I would go even further to suggest that the admiration for "engineering" lies at the heart of the reception and reinterpretation of Keynes by the American institutionalist Alvin Hansen, including the enthusiasm for econometric modeling a la Lawrence Klein.  Economists were to be engineers.
