A new triple LDU-factorization (L represents a lower-triangular block matrix, D represents the diagonal block matrix and U represents an upper-triangular block matrix) of the Leontief inverse is based on the Schur block-inversion of matrices. This factorization is applied to the decomposition of...

Various authors addressed interindustry linkages in the context of input-output systems, however many focused on the identification of key sectors in the economy. Sonis et al. (1996) offered as a field of influence theory an alternative approach focusing on the analytical importance of elements...

This paper examines comparatively the impact of information technology on urban spatial structure in the Chicago and Seoul metropolitan regions in an attempt to measure the potential influence of IT on urban form and structure. We analyzed the metropolitan areas to understand ways in which the...

In this paper, the behavior of the simple logistic map, May (1976), in the real space (R) is analyzed. Interest in the global behavior of the map, and in particular when the environmental parameter and the state variable obtain negative values, is warranted because actual, relative and negative...

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 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...

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...
