Abstract

To accept that the postulate of the Economic Theory has validity in any country is to suppose the universality to the theory. The examination of the process of cost formation in the productive system and of the income sources shows that the imposition of new cost components in the economy brings movements for income accommodation, through acceleration of inflation up to a new equilibrium level. However, the new equili-brium rate will depend of three factors: the share of the new cost components in the GDP; the participation of the contractual income, like wages, in the GDP; and the periodicity of the contractual income correction. These factors are differents from country to country, refusing the validity of monetary theory supposition. This article shows that it is possible to conclude on “non universality” of the Economic Theory. At last, if is correct to admit that larger the share of contractual incomes in the GDP more stable will be the economy, then the income policy would be a strategic factor for the stabilization policy when the economy is subject to costs shocks.
