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.
