Some Refinements of the Semi-Input-Output Method

The semi-input-output method has been proposed by the author as a substitute for what was formerly called the estimation of the indirect effects of investment projects. Essentially it rests on assumption I that a country must aim at an "ideal development process", meaning a growth process which at no time shows unutilized production capacity. Furthermore, the method rests on assumption II that a distinction can be made between national or domestic activities (industries in the widest sense or sectors) on the one hand and international activities on the other hand. By definition the products of the former cannot, for technological or cultural reasons, be imported or exported. Examples have been given elsewhere [1].
