Economic Interdependence Within the Chicago Metropolitan Area: A Miyazawa Analysis

The present study explores the nature and strength of economic interdependence between inner-city communities and suburbs within the Chicago metropolitan area. Employing Miyazawa's extended input-output framework, a multiregional model is used to investigate the interdependence of income formation and output generation. The metropolitan area is divided into four regions and particular attention is directed to predominantly minority areas on the south and west sides of the city of Chicago. The region-to-region impacts of trade flows and their associated multipliers proved to be far less important in determining the strength of interregional interdependence in contrast to income flows derived from journey-to-work movements. The interrelational income multiplier revealed considerable interdependence between regions although the strength of this interdependence was asymmetric.     

An Economic Analysis of Biproportional Properties in an Input-Output System

Various methods, such as biproportional adjustment and econometric estimating have been used to generate time series for input-output tables. In this paper, temporal changes of input-output coefficients are examined in order to analyze their behavior. Within the Chicago Region Econometric Input-Output Model, a set of input- output relationships has been extracted analytically for the period 1980–1997. Using the empirical evidence for Chicago, this paper conducts econometric time series analysis to determine whether or not certain coefficients or sets of coefficients exhibit tendencies toward stability or predictable change or whether others require more extensive econometric estimation.     

Feedback loops analysis of Japanese interregional trade, 1980-85-90

This paper examines the hierarchy of intra- and inter-regionaltrade flows within the Japanese economy over the period 1980–85–90.The methodology provides an opportunity to explore links betweenfeedback loops analysis and the extraction of a hierarchy offlows using ideas from superposition principles. The resultinganalysis of trade feedbacks may be seen to reflect the economicphenomena of horizontal and vertical trade specifications. Whilethe process is explored analytically, the results are presentedusing visualization to help identity the different permutationmatrices presenting the hierarchy of trade feedback loops.
