Linkages Impact Feedback In Light Of Linear Similarity Presentation

This document summarizes key concepts from a presentation on linear similarity between input-output matrices. It discusses how direct purchase and direct sales matrices have the same structure, with matching traces, determinants, and characteristic values, despite different appearances. It also shows that traditional multipliers and linkage indices are linearly related. The document questions some traditional assumptions around multipliers and proposes alternative approaches like considering final demand distributions and avoiding "procrustean" actions when analyzing linkages between sectors.
