สรุป	The status attainment model, introduced by Peter Blau and Otis Dudley Duncan in The American Occupational Structure (1967), is a recursive path model that explains an individual's occupational status from their social origins and intervening achievements. In its basic form, father's education and father's occupation influence the respondent's education and first job, which in turn shape current occupational status. By decomposing the link between origins and destinations into direct and education-mediated indirect paths, it established that education is the principal channel through which advantage is transmitted across generations.	The intergenerational elasticity of income (IGE) is the workhorse measure of economic mobility: the regression coefficient from regressing a child's adult log income on the parent's log income. It expresses the percentage by which a child's expected income rises for each one-percent increase in parental income, so a higher IGE means income advantages and disadvantages are more strongly transmitted across generations and society is less mobile.
