Measurement Error and Earnings Dynamics: Some Estimates from the PSID Validation Study
利用PSID验证研究数据，提出一个测量误差模型，发现收入变化的自相关在存在测量误差时仍可较准确估计，对研究收入动态的学者有参考价值。
Previous empirical work on measurement error in survey earnings data has shown that the variance of the measurement error is roughly constant over time, it is negatively correlated with true earnings, and it is autocorrelated with previous measurement errors. This paper proposes a simple model where the measurement error stems from underreporting of transitory earnings fluctuations and a white noise component. The model fits well to data from the PSID Validation Study. The results imply that autocorrelations in the changes of earnings can be estimated relatively accurately despite the presence of measurement error.
