Множественная линейная модель регрессии в условиях мультиколлинеарности
In this paper we compare age-earnings profiles between generations. Our empirical estimates are based on the Russia Longitudinal Monitoring Survey of HSE (RLMS-HSE), 1994–2015. Using intrinsic estimator, we overcome age-period-cohort problem inherent in Mincer-type earnings functions. Comparison presented in the work revealed that some male generations’ income is less than that of the young cohorts and the opposite effect for some generations of women.
Multicollinearity prevents to indentify marginal effects of cohort, age, and period regressors including them all together in Mincerian type earnings function. This is well-known age-period-cohort (APC) problem. Intrinsic estimator helps us to compare age-earnings profiles of several generations in Russia, 1994–2016. Comparison presented in this paper revealed that some male generations’ income is less than that of the young cohorts and the opposite effect for some generations of women.
In this article, we present the results of the development of the “Political Atlas of the Modern World” (“Atlas 1.0”) project. “Atlas-1.0” was implemented more than ten years ago by scholars of the MGIMO University with the support of the Institute of Public Projects and the “Expert” magazine. Development of five complex indices – of stateness, external and internal threats, the potential of international influence, the quality of life and the institutional foundations of democracy – was one of the major results of the “Atlas-1.0” project. The method of discriminant analysis was used to calculate the ratings of 191 UN member states (as well as Taiwan) as of 2005. The results obtained, reflecting various aspects of the existence of modern states, were compressed into four principal components. The four of them in the complex were interpreted as an analytical model of the modern world structure. In the project implemented ten years later at the Higher School of Economics with the support of a grant from the Russian Science Foundation (“Atlas 2.0”), the results obtained in the earlier atlas were tested for durability, corrections were made for the emergence of new UN member states, the components of the indices were refined, new statistical databases were used and advanced methods of multivariate statistical analysis were employed. The performed operations fit into the tradition of “revisited” which is part of the modern social sciences. A number of meaningful conclusions about the dynamics of the world structure have been made. The results obtained (configurations of the principal components) indicate the significant stability of the basic parameters of the world structure. At the same time, important elements of dynamics have also been revealed.
