The Determinants of Occupational Success in Britain
利用纵向数据，测量培训、学历、生病和失业经历对个人职业地位的真正影响，通过固定效应模型控制个体固定特征，避免横截面数据的估计偏差。
This paper is concerned with measuring the true impact of certain human capital variables on an individual's occupational position. The particular variables which are analysed are training, qualifications and spells of sickness and unemployment. The longitudinal nature of the data enables us to control for all relevant individual attributes which remain fixed over the period of the sample. This is vitally important because these attributes are strongly correlated with the variables of interest and would seriously corrupt estimates derived from a single cross-section. A method of generating consistent estimates (as N → ∞, T fixed) for a dynamic model with fixed effects is also illustrated.
