Attrition in Panel Survey Data and the Estimation of Multi-State Labor Market Models
分析面板调查中样本流失对劳动力市场状态转换估计的影响，通过联合建模两个随机过程来纠正因未观测因素相关性导致的估计偏误。
In the analysis of labor market transitions, spells that are incomplete due to panel survey attrition are treated as spells that are subject to independent right-censoring. It is likely, however, that the unobserved characteristics affecting individual transitions on the labor market are related to those affecting the attitude toward survey participation. In that case, the transition rate estimates are inconsistent. In this paper we analyze the relation between durations spent in labor market states and the duration of panel survey participation, by explicitly modeling and estimating both stochastic processes. We use multi-state multi-spell models which allow for stochastically related unobserved determinants.
