The Importance of Sample Attrition in Life Cycle Labor Supply Estimation
检验了非随机样本流失对生命周期劳动供给模型的影响，发现对于壮年男性，流失效应被固定效应吸收，其影响小于工资测量或工具变量选择。
We examine the importance of possible non-random attrition to an econometric model of life cycle labor supply including joint nonlinear taxation of wage and interest incomes and latent heterogeneity.We use a Wald test comparing attriters to nonattriters and variable addition testing based on formal models of attrition.Results from the Panel Study of Income Dynamics are that non-random panel attrition is of little concern for prime-aged male labor supply estimation because the effect of attrition is absorbed into the fixed effects.Attrition is less econometrically influential than research design decisions typically taken for granted; the wage measure or instrument set has a much greater impact on the estimated labor supply function of prime-aged men than how one includes panel attrition.
