Bernard C. Beaudreau is an American/Canadian economist and author of Mass Production, the Stock Market Crash and the Great Depression, The Macroeconomics of Electrification (Westport, CT: Greenwood Press, 1996), and Energy and the Rise and Fall of Political Economy (Westport, CT: Greenwood Press, 1998).
The former title maintains that the Great Depression resulted from a massive technology shock in the presence of underincome, the inability of real and nominal income to increase commensurately with productive capacity. The latter maintains that the productivity slowdown of the mid-1970s resulted from another energy shock, namely the OPEC oil embargo, whose effect on energy prices put an end to decades of energy deepening.
He is author of the energy-organization approach to material processes, an approach that combines process engineering, management and production theory.
