Abstract
This paper deals with the epistemologic problem of searching for experimental evidences of a particular economic model theory. The difficulties of such tasks are well-known due to the peculiarities of the economic system, mainly related to the non-repetitiousness of experiments. Thus, indirect evidence and other related parameter correlations must be looked for. In the present case, a Brazilian macroeconomic historical data set is analysed and some particular phenomena relating correlation between gross domestic production (GDP), fixed capital stock and electricity consumption (EC) and their respectives elasticities are presented. Developed countries, in general, present different behaviour of these variables, compared to emerging economies, not only from the point of view of absolute value aspect, but also from the point of view internal dynamic interaction process. The celebrated correlation between EC and GDP, easily verified in the data of developed countries, becomes actually a myth for the emerging countries. However, this "bad" result could be an evidence of a model proposed by the authors. (C) 2003 Elsevier B.V. All rights reserved.
