Webbapproach and constitutes the basis of input-output analyses based on input coefficients. However, note that this approach is based on the premise of stable input coefficients, as … WebbThe Causal Inference Approach uses the same basic causal structure (see diagram) as the SEM approach, albeit usually with different symbols for variables and paths. The two key differences are that the relationships between variables need not be linear and the …
