Input-Output Analysis contains new contributions to inter-industry economics by a set of internationally respected authors. The first part sketches the current state-of-the-art, ands explores the frontiers for traditional topics in input-output analysis such as interindustry linkages, feedback effects, and the composition of economic changes. The second part crosses the borders of traditional input-output analysis, covering issues that change the visualization of economic structures, the application of generalized cost functions, and the adoption of alternative modelling frameworks.Forewords; W.Isard & R.E.Kuenne Preface; M.L.Lahr & E.Dietzenbacher Introduction; E.Dietzenbacher & M.L.Lahr FRONTIERS Interindustry Linkages: The Flow Network of a Physical Input-Output Tables (PIOT): Theory and Application for Germany; G.Strassert Feedback Effects in Interregional Input-Output Models: What Have We Learned?; J.I.Round Feedbacks in Input-Output Systems: Impacts, Loops and Hierarchies; M.Sonis & G.J.D.Hewings Changes in the Structure of the Washington State Economy: 1963-1987, An Investigation of the Patterns of Inputs and the Mix of Outputs; W.B.Beyers An Intercountry Decomposition of Output Growth in EC Countries; E.Dietzenbacher Interaction Terms and Structural Decomposition: An Application to the Defense Cost of Oil; S.D.Casler Interregional Trade, the Heckscher-Ohlin-Vanek Theorem, and Leontief's Paradox; S.He & K.Polenske Perfect Aggregation of Industries in Input-Output Models; J.A.Olsen Export Base Theory and Input-Output Systems: Some Formal Results; A.Guccoine & W.J.Gillen A Strategy for Producing Hybrid Regional Input-Output Tables; M.L.Lahr EXTENSIONS Structural Development of Germany, Japan and US, 1980-1990: A Qualitative Analysis Using MFA (Minimal Flow Analysis); H.Schnabl On Boolean Topological Methods of Analysis; L.de Mesnard The Question of Finding Industrial Clusters Revisited: A Qualitative Perspective; F.Aroche-Reyes Influencel£P
