Structural Transformations and Important Coefficients in the North American Economies

This paper assesses a few issues related to the question of finding the so-called important coefficients in an input-output table. Further, these coefficients are located in the corresponding matrices of Canada, the USA and Mexico. Important coefficients are analysed employing graph theoretical tools as well as qualitative input-output concepts and techniques. Empirical results are discussed in terms of the possible implications for trade and regional integration which, presumably, would have deepened in the 1990s.
