Path Diagrams to Illustrate Causality
An early use of "Path analysis" was by Peter Blau and Otis Dudley Duncanin The American Occupational Structure (1978). They analyzed data collected from a sample of adult male children and their families and proposed a simple model of the occupational attainment process:
Note: the lower case eE and eO stand for other factors that effect outcomes.
"Each … direct effect … needs to have a theoretical statement about the mechanism that … generat[es] the observable association. Higher father's education may affect son's education by providing the child with higher expectations, and support for attainment. …One of the key insights of the Blau-Duncan model is that the effects of ascriptive characteristics on the son's success may be both direct and indirect" (Hanneman).
