A Book by American Economists on the "Input-Output Method"

In our country, ever greater significance attaches to investigations having to do with the application of mathematical methods in economic analysis planning, and, in particular, of contemporary computer equipment. It was noted at the 21st Congreas of the Communist Party of the Soviet Union that large scale introduction of machine mathematics into the work of planning and designing organizations would provide a colossal economy and that lagging in this field is impermissible. Economic investigations with the use of mathematical methods should be based on a profound qualitative analysis of the processes and phenomena being studied. A major role in these investigations is played by the method of balance accounts, the solution of extremum problems, etc., developed in the Soviet Union.
