Earnings and Capability Requirements
利用美国1950和1960年人口普查及职业名称词典数据，通过因子分析提取基本能力并估计隐性能力价格，研究收入与职业能力要求的关系。
This paper empirically investigates the relationship between earnings and capability requirements in the United States.Emphasis is on the need to use data on the capability requirements of an individual's job rather than on an individual's capability endowments.Data are taken from the 1950 and 1960 Censuses and from the Dictionary of Occupational Titles (DOT).Using factor analysis, the DOT data are searched for some underlying basic capabilities; next, implicit capability prices are estimated.Non-:-linearity in the earnings function is analyzed, and price changes over time are studied as well.
