I argue that the empirical strategies for estimation of the intergenerational elasticity of lifetime earnings that are currently employed in the literature might not eliminate bias arising from lifecycle effects. Specifically, I demonstrate that procedures based on the generalized errors-invariables model suggested by Haider and Solon (2006) or the consideration of differential earnings growth rates across subpopulations may not yield unbiased or consistent estimates. I further argue that instrumental variable estimators will not identify an upper bound for the true population parameter.
