Evidence on the Validity of Cross-Sectional and Longitudinal Labor Market Data
利用PSID验证研究，通过对比工人调查数据与公司工资记录，评估了劳动力市场变量（如年收入、时薪）的报告误差性质，发现年收入报告较准确，但误差与真实收入负相关，且收入变化和时薪的误差更大。
This article investigates error properties of survey reports of labor market variables. We use the Panel Study of Income Dynamics (PSID) Validation Study, a two-wave panel survey of workers employed by a large firm that shared its detailed payroll records. Individuals' reports of annual earnings are fairly accurate. Errors are negatively related to true earnings, reducing bias due to measurement error when earnings are used as an Independent variable. Biases are moderately larger for changes in earnings. Earnings per hour are less reliably reported than annual earnings. Biases in estimating earnings functions are relatively small, but those in labor supply functions may be important. Copyright 1994 by University of Chicago Press.
