In this paper, two literatures that have explored the structure of economies are brought together. In the first case, the approaches to key sector identification (initially associated with Hirschman and Rasmussen) that were modified by Cella, Clements and Rossi and Guilhoto et al. to reveal what...

The identification and interpretation of regional economic structure is addressed by reference to a four region, three sector interregional input-output table for the US for 1982. Using the transactions matrix, a succession of self-influence feedback loops are identified, first at the...

This paper presents a description of some fundamental properties of networks of economic selfinfluence and transfer of economic influence within hierarchies of economic sub-systems using structural path analysis within a multiregional input-output system. In this fashion, exchange between...

The effects of structural change in all sectors of some regions in multiregional input-output systems are explored in this paper. For each region, the changes in direct inputs are decomposed into a matrix of intraregional changes and a matrix of interregional backward linkage changes. This...

In this paper we consider the matrix forms of the Sraffa-Leontief income distribution model introduced by Steenge (1995, 1997). We will explore the equivalence between these matrix forms and the set of simpler models, including the Sraffian condition of linear relations between the rate of...
