----------------- HES POSTING ----------------- I didn't follow the whole discussion on economics and engineering but the swiss-german economist Walter G. Waffenschmidt (1887-1980) may be interesting in this concern: He planed to build a machine, a model of economic circular flow already in 1957. He tried to found a new discipline called "Wirtschaftsmechanik" (also the title of his 1957-book). He was an engineer as well as an economist and influenced by Wiener's cybernetics.
