Extended Input-Output Models: Progress and Potential

This article presents a critical survey of research on extended input-output models, emphasizing recent developments in demographic-economic and socio-economic analysis. Basic principles of model design and construction are reviewed, by reference to a representative selection of extended models. Two research themes—labor market analysis and income distribution—are pursued in greater detail as examples of the directions of current work. A comparison is made between extended models and social accounting matrices. The closing section contains a discussion of the prospects for future research.
