This survey of regional input-output models and their use in impact analysis evolved from over twenty years of experience in constructing regional economic models and in teaching about them. Its objectives are to present this family of models in an easily understood format, to show that the models we use in economics are well-structured, and to provide a basis for understanding applications of these models in impact analysis. The models are presented in such a way that understanding the logic and algebra of the simplest economic-base model leads to an understanding of the only slightly more complex regional and interregional input-output models in common use today. The advanced models become matrix-algebra extensions of the simple models.
