Post-War Businesses and Keynesianism, 12th Jan., 2011.

H. W. Arndt has an article about Keynesianism's effect on British businesses after World War II.

If there is general agreement that world prosperity is a condition of British prosperity, there is even more striking unanimity on the method of approach to that goal: all five reports accept the "under-consumption" theory--so recently rank heresy in the eyes of business men and economists--in one form or another (the London C. of C. in terms reminiscent of Major Douglas). The root of the trouble has been the gap between potential and effective consumers' demand, the deficit in our "monetary mechanism" for the distribution of purchasing power. If one may judge by these reports, British business has been more than adequately converted to "Keynesianism".
