خلاصه	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.	Sequence analysis is a holistic method for studying ordered categorical trajectories — such as month-by-month employment states, family life-course events, or daily activity patterns — by treating each individual's whole sequence as a unit, measuring how dissimilar pairs of sequences are, and grouping them into a typology of characteristic pathways. Introduced to sociology by Andrew Abbott, it shifts attention from isolated transitions to the shape of entire life courses.
