Intergenerational Elasticity
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.
