JOURNAL OF ECONOMIC INEQUALITY 2023年 第1期21卷 25-45页
作者: Bavaro, Michele Tullio, Federico Univ Oxford INET Oxford England Univ Oxford Dept Social Policy & Intervent Oxford England Bank Italy DG Econ Stat & Res Rome Italy
We propose a multivariate approach for the estimation of intergenerational transition matrices. Our methodology is grounded on the assumption that individuals' social status is unobservable and must be estimated. ... 详细信息
