Many authors stress the importance of relationships between sectors for the economic growth. Therefore the concept of linkage appears in the definition of two of the most traditional concepts in the input-output analysis: the “key sector” and cluster. In this paper, key products and...

The input-output structural analysis is a valuable tool when designing economic policies since it allows us to know which are the most important linkages and sectors of an economic system. The coefficients' sensitivity analysis is one of the major approaches of the structural analysis. With it...

The paper introduces an alternative method to determine "sensitivity' within an input-output-context and makes the most sensitive connections visible in an overall graph. The method called ECA (Elasticity Coefficient Analysis) tries—like the Important Coefficient Analysis (ICA)—to derive...

A wide range of approaches are available for classifying coefficients according to their importance to an economy. The 'tolerable limits' approach is one that has been extensively written about. Nevertheless, it seems unsuitable for assessing the overall importance of a coefficient to an...
